ISO 20816-8 Pistonli Kompressorlar uchun Tebranish Chegaralari
ISO 20816-8 nima va u qaytma kompressorlar uchun nima uchun muhim?
ISO 20816-8 — qaytma kompressorlar uchun, jumladan, texnologik gaz, havo va sovutgich turlari uchun tebranish darajasini baholash mezonlarini belgilovchi xalqaro standart. U mm/s RMS da o'lchanadigan tezlik asosida to'rtta tebranish zonasini (A, B, C, D) belgilaydi va muhandislarga kompressor ruxsat etilgan chegaralar doirasida ishlayotganini yoki tuzatuvchi chora talab qilinishini aniqlashga yordam beradi.
Qaytma kompressorlar markazdan qochma yoki o'qli kompressorlar kabi aylanuvchi mashinalardan tubdan farq qiladi. Qaytma konstruksiyalarga xos bo'lgan porshen-krank mexanizmi va pulsatsiyalovchi gaz kuchlari normal ishlash jarayonida sezilarli darajada yuqori tebranish darajalarini hosil qiladi. Shu sababli ISO 20816-8 ISO 20816 oilasining alohida qismi sifatida mavjud — aylanuvchi mashinalar standartlaridagi (masalan, ISO 20816-3) chegaralarni qaytma kompressorlarga qo'llash noto'g'ri va haddan tashqari konservativ baholarga olib keladi.
The scope of ISO 20816-8 is specific: it applies to reciprocating compressor systems mounted on rigid foundations, with typical operating speeds from 120 r/min to 1800 r/min. Rotating and torsional shaft vibration, as well as the vibration of drivers (electric motors, engines) and driven auxiliary equipment, are outside its scope and must be evaluated using the other applicable standards for those machine types.
The Tebranish chegaralari — qaytma kompressorlar Ushbu muhandislik to'plamidagi bepul onlayn vosita brauzer asosidagi kalkulyatorda ISO 20816-8 zona tasnifini amalga oshiradi. Muhandislar o'lchangan tebranish tezligini kiritishi, kompressor turi va poydevor turini tanlashi va darhol tegishli tebranish zonasini hamda operatsion tavsiyalarni olishi mumkin — elektron jadvallar yoki qo'lda jadval izlash talab etilmaydi.
Qattiq poydevorlar uchun ISO 20816-8 tebranish zona chegaralari qanday?
Bino konstruksiyasiga to'g'ridan-to'g'ri ulangan qattiq beton yoki po'lat blok poydevordagi qaytma kompressorlar uchun ISO 20816-8 uchta zona chegarasini belgilaydi: A/B — 7,1 mm/s RMS, B/C — 14,0 mm/s RMS va C/D — 28,0 mm/s RMS. A zonasi yangi ishga tushirilgan yoki a'lo holatni, D zonasi esa shikast yetkazishi mumkin bo'lgan darajada yuqori tebranishni bildiradi.
| Zone Boundary | Tezlik chegarasi (mm/s RMS) | Operatsion talqin |
|---|---|---|
| A/B | 7.1 | Yangi ishga tushirilgan (a'lo) holatdan uzoq muddatli ishlash uchun qabul qilinadigan holatga o'tish |
| B/C | 14.0 | Qabul qilinadigan holatdan cheklangan ishlatishga o'tish — tergov tavsiya etiladi |
| C/D | 28.0 | Cheklangan ishlatishdan xavfli holatga o'tish — ishlashni davom ettirishda shikast yetkazish xavfi |
Qattiq poydevorlar yirik texnologik gaz kompressorlari uchun neftni qayta ishlash va kimyo zavodlarida eng keng tarqalgan o'rnatish usuli hisoblanadi. Poydevor massasi va qattiqligi rama harakatini cheklaydi, shu sababli zona chegaralari moslashuvchan (yay izolyatsiyali) o'rnatishlarga nisbatan pastroq. Masalan, qattiq poydevordagi texnologik gaz kompressorida 12 mm/s RMS ko'rsatmasi B zonasiga — cheklovsiz uzoq muddatli ishlash uchun qabul qilinadigan holatga to'g'ri keladi.
Does ISO 20816-8 Cover Flexible (Spring-Isolated) Foundations?
No — ISO 20816-8 applies to reciprocating compressors mounted on rigid foundations and does not define a separate zone table for flexible (spring-isolated) installations. For spring-isolated machines, the tool offers optional engineering guidance boundaries — A/B at 9.0 mm/s RMS, B/C at 18.0 mm/s RMS, and C/D at 36.0 mm/s RMS — extrapolated from the rigid-foundation values to reflect the additional frame motion that spring isolation permits. These guidance values are not part of ISO 20816-8, and an assessment based on them should not be reported as an ISO 20816-8 zone classification.
| Zone Boundary | Rigid Foundation — ISO 20816-8 (mm/s RMS) | Flexible Foundation — extrapolated guidance, not in ISO 20816-8 (mm/s RMS) | Oshish koeffitsienti |
|---|---|---|---|
| A/B | 7.1 | 9.0 | ×1.27 |
| B/C | 14.0 | 18.0 | ×1.29 |
| C/D | 28.0 | 36.0 | ×1.29 |
Yay izolyatsiyali o'rnatishlar bino ichidagi havo kompressorlari va sovutgich kompressorlari uchun keng tarqalgan bo'lib, bu holatlarda konstruksiyaga uzatiladigan tebranishni minimallashtirish zarur. Moslashuvchan poydevor kompressor ramasiga past chastotalarda erkinroq harakatlanish imkonini beradi va inersiya kuchlarini uzatish o'rniga yutadi. Muhandislar kalkulyatorda foydalanishdan oldin poydevor turini to'g'ri aniqlashlari kerak Tebranish chegaralari — qaytma kompressorlar tool; selecting the wrong foundation type can shift the zone classification by one full zone and lead to incorrect maintenance decisions. Keep in mind that only the rigid-foundation assessment is a true ISO 20816-8 classification — the flexible-foundation option applies the extrapolated guidance values described above, which lie outside the scope of the standard.
Porshenli kompressorlarning tebranish chegaralari aylanuvchi mashinalar chegaralaridan qanday farq qiladi?
Reciprocating compressors have significantly higher acceptable vibration levels than rotating machines. The Zone A upper limit for reciprocating compressors on rigid foundations is 7.1 mm/s RMS — roughly five times the 1.4 mm/s RMS Zone A/B boundary for a medium-size rotating machine (ISO 20816-3, formerly ISO 10816-3, Group 2 on rigid support). This difference exists because the reciprocating mechanism inherently generates higher vibration that is considered normal operation.
| Parameter | Porshenli kompressorlar (ISO 20816-8, qattiq poydevor) | Rotating Machines (ISO 20816-3, Group 2, Rigid Support) | Ratio |
|---|---|---|---|
| A/B zonasi chegarasi | 7.1 mm/s RMS | 1.4 mm/s RMS | 5.1× |
| B/C zonasi chegarasi | 14.0 mm/s RMS | 2.8 mm/s RMS | 5.0× |
| C/D zonasi chegarasi | 28.0 mm/s RMS | 4.5 mm/s RMS | 6.2× |
| Asosiy tebranish manbai | Piston-krank inersiya kuchlari, gaz pulsatsiyasi | Rotor muvozanatsizligi, vallarning noto'g'ri birikishi | — |
| Dominant chastota tarkibi | 1×, 2×, and higher orders of running speed | Asosan 1× aylanish tezligi | — |
Ushbu taqqoslash muhim muhandislik tamoyilini ko'rsatib beradi: tebranish chegaralari mashina turiga xos bo'ladi. Porshenli kompressorga aylanuvchi mashina chegaralarini qo'llash deyarli har bir agregatni haddan ortiq tebranish bo'yicha belgilashga, keraksiz to'xtashlarga va texnik xizmat resurslarining behuda sarflanishiga olib keladi. Aksincha, markazdan qochma kompressorga porshenli kompressor chegaralarini qo'llash chinakam xavfli tebranishning aniqlanmasdan qolishiga sabab bo'lishi mumkin. Ushbu Tebranish chegaralari — qaytma kompressorlar asbob foydalanuvchining mashina tanloviga asosan to'g'ri standartning avtomatik ravishda qo'llanilishini ta'minlaydi.
ISO 20816-8 dagi to'rtta tebranish zonasi (A, B, C, D) nimani anglatadi?
ISO 20816-8 dagi to'rtta zona tebranish shiddatini amaliy toifalarga ajratadi: A zonasi yangi ishga tushirilgan mashinalar uchun odatiy a'lo holatni ifodalaydi; B zonasi uzoq muddatli ruxsat etilgan ishni bildiradi; C zonasi tebranish tekshirishni va cheklangan ishlashni talab qiladigan darajaga yetganini anglatadi; D zonasi esa zudlik bilan choralar ko'rishni talab qiluvchi shikast yetkazilish xavfining yaqinlashganidan dalolat beradi.
- Zone A — Yangi ishga tushirilgan yoki yaqinda kapital ta'mirdan o'tgan porshenli kompressorlar uchun odatiy tebranish darajalari. Hech qanday chora talab etilmaydi. Bu qabul sinovi uchun asosiy maqsadli ko'rsatkich hisoblanadi.
- Zone B — Uzluksiz uzoq muddatli ishlash uchun ruxsat etilgan tebranish darajalari. Odatdagi xizmatdagi kompressorlarning aksariyati ushbu zona ichida ishlaydi. Monitoring odatdagi oraliqda davom ettirilishi kerak.
- Zone C — Uzluksiz ishlash uchun qabul qilib bo'lmaydigan tebranish darajalari. Kompressor tuzatuvchi choralar rejalashtirilayotgan vaqt davomida cheklangan muddatga ishlashda davom ettirishi mumkin, ammo ildiz sababini tekshirish zudlik bilan boshlanishi kerak. Keng tarqalgan sabablar orasida krestgolova yo'naltiruvchilarining eskirishi, poydevor boltlarining bo'shashi yoki gaz pulsatsiyasi rezonansi kiradi.
- Zone D — Kompressor, quvurlar yoki poydevorga tezkor zarar yetkazish uchun yetarlicha kuchli tebranish darajalari. Zudlik bilan to'xtatib qo'yish yoki yukni kamaytirish tavsiya etiladi. D zonasida ishlashni davom ettirish podshipniklar, tirsakli val yoki bosim ostidagi komponentlarning halokatli ishdan chiqishiga olib kelishi mumkin.
Zona tizimi operatsion, texnik xizmat ko'rsatish va ishonchlilik muhandisligi jamoalari o'rtasida universal muloqot tizimini ta'minlaydi. Muayyan tebranish qiymatining “yuqori” yoki “past” ekanligini muhokama qilish o'rniga, jamoalar turli kompressor turlari va o'rnatmalar bo'yicha izchil qarorlar qabul qilish uchun ISO 20816-8 zona tasnifiga murojaat qilishlari mumkin.
ISO 20816-8 qanday kompressor turlarini qamrab oladi?
ISO 20816-8 covers all major categories of reciprocating compressors: process gas compressors used in refineries and chemical plants, industrial air compressors for plant utilities, and refrigeration compressors used in HVAC and industrial cooling systems. The same ISO 20816-8 zone boundary structure applies to all three types when they are mounted on rigid foundations; for spring-isolated installations the tool applies the extrapolated non-ISO guidance values described above.
- Jarayon gazi kompressorlari — Vodorod, tabiiy gaz, etilen va boshqa jarayon gazlarini qayta ishlaydigan odatda katta, ko'p bosqichli, sekin aylanadigan (300–600 RPM) mashinalar. Odatda qattiq temir-beton poydevorlarga o'rnatiladi. Bu mashinalar yonuvchan yoki zaharli xizmat tufayli eng yuqori oqibatli qo'llashni ifodalaydi.
- Havo kompressorlari — Korxonaga havo ta'minoti uchun ishlatiladigan o'rta va katta porshenli havo kompressorlari (odatda 500–1800 RPM). O'rnatish talablariga qarab qattiq yoki moslashuvchan poydevorlarga o'rnatiladi. Havo kompressori tebranish muammolari ko'pincha klapan eskirishi yoki razgruzchik nosozligidan kelib chiqadi.
- Sovutgich kompressorlari — Ammiak sovutish tizimlarida, sanoat sovutgich qurilmalarida va sovuq saqlash omborlarida ishlatiladigan ochiq yoki yarim germetik porshenli kompressorlar. Ular yuqoriroq tezliklarda (900–1750 RPM) ishlashi mumkin va odatda band joylarga shovqin va tebranish uzatilishini kamaytirish uchun yay izolyatsiyasiga ega bo'ladi.
The Tebranish chegaralari — qaytma kompressorlar tool supports all three compressor types with appropriate quick-preset values. For example, the tool includes presets of 12 mm/s for a process compressor on a rigid foundation (Zone B), 20 mm/s for an air compressor (Zone C on rigid; also Zone C under the flexible-foundation guidance values), and 8 mm/s for a refrigeration compressor (Zone B on rigid; Zone A under the flexible-foundation guidance values).
Nima uchun pulsatsiya natijasida yuzaga keladigan quvur tebranishi ISO 20816-8 tomonidan qamrab olinmagan?
ISO 20816-8 faqat kompressorda ramka va podshipnik korpusining tebranishini ko'rib chiqadi. Pulsatsiya natijasida yuzaga keladigan quvur tebranishi — ko'pincha porshenli kompressor o'rnatmalarida tebranishning eng muhim muammosi — Energy Institute Guidelines for the Avoidance of Vibration Induced Fatigue Failure in Process Pipework yoki API 618 pulsatsiya tadqiqoti talablari kabi standartlardan foydalangan holda alohida baholanishi kerak.
Porshenli kompressorlar ish tezligi va silindrlar sonining ko'paytmalari bo'yicha gaz bosimi pulsatsiyalarini hosil qiladi. Bu pulsatsiyalar ulangan quvur tizimi orqali tarqaladi va quvur bo'laklari, kichik o'lchamli ulanishlar va asbob naylarining mexanik rezonans chastotalarini qo'zg'atishi mumkin. 2019 yilgi Energy Institute tadqiqotiga ko'ra, quvur tebranishidan kelib chiqadigan charchoq sinishi yoqilg'i-energetika sanoatining yuqori oqimli qismidagi barcha uglevodorod chiqishlarining taxminan 20% ini tashkil qiladi va bu uni tarkib yo'qotish hodisalarining asosiy sababiga aylantiradi.
Bu farq muhimdir: kompressor ISO 20816-8 ga ko'ra ramka tebranishi butunlay maqbul (A yoki B zonasi) bo'lishi bilan bir vaqtda, haftalar ichida charchoq sinishiga olib kelish uchun yetarlicha kuchli quvur tebranishiga ega bo'lishi mumkin. Porshenli kompressor o'rnatmalarida tebranishni baholashni amalga oshirayotgan muhandislar har doim ham ISO 20816-8 ga muvofiq kompressor ramkasi tebranishini, ham tegishli quvur tebranishi standartlariga muvofiq bog'liq quvur tebranishini baholashlari kerak.
Bepul onlayn ISO 20816-8 tebranishni baholash vositasidan qanday foydalaniladi?
The Tebranish chegaralari — qaytma kompressorlar free online tool requires three inputs: compressor type (process gas, air, or refrigeration), foundation type (rigid or flexible), and the measured vibration velocity in mm/s RMS. The tool instantly returns the applicable vibration zone, the zone boundary values, and an operational recommendation — based on ISO 20816-8 criteria for rigid foundations, or on the tool’s extrapolated guidance values for flexible foundations.
- Kompressor turini tanlang — Jarayon gazi kompressori, havo kompressori yoki sovutgich kompressoridan birini tanlang. Zona chegaralari hozirda uchta tur uchun bir xil bo'lsa ham, bu tanlov tavsiya matni uchun tegishli kontekstni ta'minlaydi va kompressor turiga ko'ra farqlashi mumkin bo'lgan kelajakdagi standart tahririyatlarini qo'llab-quvvatlaydi.
- Poydevor turini tanlang — Choose Rigid Foundation or Flexible (Spring-Isolated). This selection determines which set of zone boundaries applies; note that only the rigid-foundation boundaries come from ISO 20816-8, while the flexible option uses the tool’s extrapolated non-ISO guidance values. If uncertain, inspect the compressor mounting: rigid foundations have the frame bolted directly to concrete or steel; flexible foundations have visible spring or rubber isolation elements between the frame and the support structure.
- O'lchangan tezlikni kiriting — Kompressor ramasi yoki podshipnik korpusida o'lchangan umumiy tebranish tezligini mm/s RMS birligida kiriting. O'lchovlar maksimal tebranish yo'nalishida, odatda tirsakli valga perpendikulyar gorizontal yo'nalishda olinishi kerak.
- Review results — The tool displays a color-coded zone indicator (A = green, B = yellow, C = orange, D = red), the measured value relative to zone boundaries, and a specific operational recommendation.
Keng tarqalgan stsenariylar uchun tezkor oldindan sozlamalar mavjud: qattiq poydevorda jarayon kompressori uchun 12 mm/s, havo kompressori uchun 20 mm/s va sovutish kompressori uchun 8 mm/s. Ushbu oldindan sozlamalar muhandislarga o'z o'lchov ma'lumotlarini kiritishdan oldin asbobning funksionalligini tezda o'rganish va zona tasniflari qanday ishlashini tushunish imkonini beradi.
ISO 20816-8 baholashlari uchun qanday o'lchov amaliyotlari tavsiya etiladi?
ISO 20816-8 assessments require vibration velocity measurements in mm/s RMS taken on the compressor frame or main bearing housings. Measurements should be taken at steady-state operating conditions in all three axes (horizontal, vertical, axial), with the highest value used for zone classification. Broadband measurements covering at least 2–1000 Hz are recommended.
- O'lchov parametri: Tezlik, mm/s RMS (o'rtacha kvadratik qiymat). Cho'qqi yoki cho'qqi-cho'qqi qiymatlarini ishlatmang — ular to'lqin shaklining xususiyatlariga qarab og'irlik darajasini 40–100% ga oshirib ko'rsatadi.
- O'lchov joylari: Asosiy podshipnik korpuslari, krutsshtopar yo'naltiruvchi korpuslari va tirsakli val o'qi yaqinidagi rama yuzalari. Yupqa qopqoqlar, klapan qopqoqlari yoki quvurlarda o'lchov olmang — bu joylar rama tebranishini ifodalamagan holda mahalliy rezonans kuchayishini ko'rsatadi.
- Chastota diapazoni: Broadband measurement covering at least 2 Hz to 1000 Hz. Reciprocating compressors generate significant energy at low frequencies (1× and 2× running speed), so instruments with adequate low-frequency response are essential. Standard accelerometers with high-pass filters set above 10 Hz may miss critical low-frequency content.
- Ish sharoitlari: O'lchovlar normal, barqaror ish yuklamasi sharoitida olinishi kerak. Ishga tushirish, to'xtatish yoki yuklamasiz ishlash vaqtidagi tebranish vakillik qilmaydi va zona tasniflash uchun ishlatilmasligi kerak.
- O'qishlar soni: Takrorlanishni tekshirish uchun har bir nuqtada kamida uchta ketma-ket o'lchov oling. Qayta-qayta harakatlanadigan kompressorlarning tebranishi gaz yuklamasi, klapan holati va issiqlik holatiga qarab o'zgarishi mumkin.
ISO 20816-8 ISO 20816 standartlar oilasiga qanday bog'liq?
ISO 20816-8 tebranishni baholash standartlarining ISO 20816 oilasidagi bir necha mashinaga xos bo'limlardan biridir. Har bir bo'lim o'sha muayyan uskunaning tebranish xususiyatlariga moslashtirilgan zona chegaralari bilan turli mashina toifasini ko'rib chiqadi. Ushbu oila eski ISO 10816 va ISO 7919 seriyalarini almashtirgan va birlashtirgan.
| Standard Part | Machine Type | ISO 20816-8 dan asosiy farq |
|---|---|---|
| ISO 20816-1 | Umumiy ko'rsatmalar | Doiraviy standart; muayyan zona chegaralarini belgilamaydi |
| ISO 20816-3 | Sanoat mashinalari (nasoslar, motorlar, ventilyatorlar, kompressorlar > 15 kW) | Faqat aylanuvchi mashinalar uchun; sezilarli darajada pastroq tebranish chegaralari |
| ISO 20816-5 | Gidravlik turbinalar va nasos-turbinalar | Gidrogeneratorlarda val va konstruktiv tebranishlarni qamrab oladi |
| ISO 20816-8 | Qaytma kompressorlar | Qaytma mexanizm kuchlari ta'sirini aks ettiruvchi eng yuqori zona chegaralari |
| ISO 20816-9 | Gear units | Tishli uzatma chastotalarini va tish ilashishidagi kuchlarni hisobga oladi |
| ISO 20816-21 | Wind turbines | O'zgaruvchan shamol yuklamalari ostida gondola va minora tebranishlarini ko'rib chiqadi |
ISO 20816-8 ning ushbu standartlar oilasidagi o'rnini tushunish muhandislarga keng tarqalgan xatoni — o'z mashinalari uchun standartning noto'g'ri qismini qo'llashni — oldini olishga yordam beradi. Masalan, neftni qayta ishlash zavodida ishlaydigan ishonchlilik muhandisiga markazdan qochma nasoslar va motorlar uchun ISO 20816-3, qaytma kompressorlar uchun ISO 20816-8, hamda tishli uzatmalar uchun ISO 20816-9 kerak bo'lishi mumkin — bularning barchasi bitta zavodda qo'llaniladi.
Ko'p beriladigan savollar
Qaytma kompressor uchun qanday tebranish darajasi maqbul hisoblanadi?
For reciprocating compressors on rigid foundations, vibration velocity up to 7.1 mm/s RMS is considered excellent (Zone A), and up to 14.0 mm/s RMS is acceptable for unrestricted long-term operation (Zone B) per ISO 20816-8. For flexible (spring-isolated) foundations ISO 20816-8 does not define limits; the tool’s extrapolated engineering guidance uses 9.0 and 18.0 mm/s RMS respectively.
Qaytma kompressor uchun ISO 20816-3 chegaralaridan foydalanish mumkinmi?
No. ISO 20816-3 applies exclusively to rotating machines. Reciprocating compressors generate inherently higher vibration due to the piston-crank mechanism, and their acceptable levels are several times higher than typical rotating machine limits. Always use ISO 20816-8 for reciprocating compressors to avoid false alarms and unnecessary shutdowns.
Does ISO 20816-8 define limits for flexible (spring-isolated) foundations?
No. ISO 20816-8 applies to reciprocating compressors on rigid foundations and defines zone boundaries for rigid installations only. The flexible-foundation values offered by the tool (for example, 9.0 mm/s at the A/B boundary versus 7.1 mm/s for rigid) are extrapolated engineering guidance — approximately 27–29% above the rigid boundaries, reflecting the additional frame motion allowed by the isolation system — and are not ISO 20816-8 limits.
ISO 20816-8 qaytma kompressorlardagi quvur tebranishlarini qamrab oladimi?
Yo'q. ISO 20816-8 faqat kompressor ramasi va podshipnik qutisi tebranishlarini qamrab oladi. Ko'pincha eng muhim muammo hisoblangan pulsatsiyadan kelib chiquvchi quvur tebranishlari — Energy Institute ko'rsatmalari yoki loyihalash bosqichida API 618 pulsatsiya va mexanik reaksiya tadqiqotini amalga oshirish kabi alohida standartlar yordamida baholanishi kerak.
ISO 20816-8 uchun tebranishni siljish, tezlik yoki tezlanish orqali o'lchash kerakmi?
ISO 20816-8 zone boundaries are defined in velocity, specifically mm/s RMS. Use broadband velocity measurements covering at least 2–1000 Hz. If your instrument measures acceleration, ensure it has software-based integration to convert to velocity with adequate low-frequency response, as reciprocating compressors produce significant energy at 1× and 2× running speed (often below 20 Hz).
Qaytma kompressorlarda tebranishni qanchalik tez-tez o'lchash kerak?
ISO 20816-8 muayyan monitoring intervalini belgilamaganligi bilan birga, sanoat amaliyoti muhim bo'lmagan kompressorlar uchun marshrutga asoslangan oylik o'lchashlarni, kritik texnologik gaz kompressorlari uchun esa uzluksiz onlayn monitoringni tavsiya etadi. C zonasida ishlaydigan mashinalar tuzatuvchi chora ko'rilmaguncha yuqori chastotada (haftalik yoki uzluksiz) kuzatilishi lozim.
Qaytma kompressorlarda tebranishning yuqori bo'lishining umumiy sabablari qanday?
Keng tarqalgan sabablar quyidagilarni o'z ichiga oladi: krosshead yoki piston shtoki zichlagichining eskirishi, poydevordagi mahkamlash vintlarining bo'shashi, qarama-qarshi silindrlarning muvozanatsizligi, kompressor klapanlarining yeyilib ketishi yoki o'tkazib yuborishi, quvur tizimidagi gaz pulsatsiyasining rezonansi, kompressor va haydovchi o'rtasidagi nosozlik, shuningdek, krank vali yoki podshipniklarning eskirishi. Tebranishning chastota tarkibi (spektral tahlil) ushbu asosiy sabablarni bir-biridan ajratishga yordam beradi.
«Tebranish chegaralari — Qaytma kompressorlar» vositasidan foydalanish bepulmi?
Ha. «Tebranish chegaralari — Qaytma kompressorlar» vositasi — ISO 20816-8 zona tasnifini amalga oshiruvchi bepul brauzerga asoslangan muhandislik kalkulyatori (Bepul muhandislik vositasi №024). U ro'yxatdan o'tishni, dasturiy ta'minotni o'rnatishni yoki to'lovni talab qilmaydi. Muhandislar o'lchangan tebranish qiymatlarini kiritib, operatsion tavsiyalar bilan birga zona tasnifini darhol olishlari mumkin.
