Stendi ya Kusawazisha Rotori kwa Kasi ya Juu kwa Pampu za Utupu<\/h1>\n

Utangulizi<\/h2>\n

Balancing of high-speed rotors in vacuum pumps requires specialized equipment capable of maintaining accuracy under extreme operational conditions. To meet these requirements, dedicated balancing stands were developed in 2002 and 2009. These systems are designed for dynamic balancing of assembled turbine rotors at actual operational speeds ranging from 42,000 to 60,000 rpm, directly in their own bearing supports. The design objective was to achieve residual imbalance values in accordance with Class 1 accuracy as per GOST 22061-76, the Soviet balance quality standard (its modern international counterpart is ISO 21940-11, formerly ISO 1940-1).<\/p>\n

Muundo na Mpangilio wa Kimuundo<\/h2>\n

Kielelezo cha 1 kinaonyesha mpango wa muundo wa stendi ya kusawazisha kwa kasi ya juu inayotumika kwa rotori za pampu za utupu.<\/p>\n

Kielelezo cha 1 \u2013 Mpango wa kimuundo wa stendi ya kusawazisha pampu za utupu kwa kasi ya juu:<\/strong>
1 \u2013 Jukwaa imara
2 \u2013 Manyunyizi ya silinda ya kuzuia mtetemo
3 \u2013 Msingi wa usakinishaji wa silinda
4 \u2013 Pampu ya utupu iliyosawazishwa
5 \u2013 Kifuniko cha kinga
6 \u2013 Kipimo cha pembe ya awamu
7 \u2013 Kipimo cha mtetemo kwenye kifuniko
8 \u2013 Kipimo cha mtetemo kwenye msingi
9 \u2013 Kitengo cha kupima na kuhesabu<\/p>\n

Stendi imejengwa kwenye jukwaa la mstatili (1), linalosaidiwa na chemchemi nne za silinda (2), ambazo zinazuia mtetemo. Jukwaa limeimarishwa kwa viunzi vya longitudinal na transverse, vinavyofikia ugumu wa juu huku kupunguza uzito. Suluhisho hili la kimuundo linahakikisha unyeti wa juu kwa nguvu za kutosawazika na kuzuia mtetemo wa resonance katika mzunguko wote wa kasi wa pampu wakati wa usawazishaji.<\/p>\n

Msingi wa usakinishaji (3) umefungwa kwa nguvu kwenye jukwaa na hutumika kuweka pampu (4) kwa usahihi. Pampu imefunikwa na kifuniko maalum (5), ambacho pia kinabeba kipimo cha pembe ya awamu (6). Vipimo viwili vya mtetemo (7 na 8) vimewekwa kwenye kifuniko na msingi, mtawalia. Vipimo vyote vimeunganishwa na kitengo cha kupima na kuhesabu (9), ambacho hufanya uchambuzi wa wakati halisi na kuhesabu uzito wa urekebishaji.<\/p>\n

Utaratibu wa Kusawazisha<\/h2>\n

Usawazishaji unafanywa katika hatua mbili zinazofuatana ili kuhakikisha usahihi chini ya hali za rotori ngumu na zinazonyumbulika.<\/p>\n

Hatua ya 1 \u2013 Usawazishaji wa Rotori Ngumu<\/h3>\n

In the initial stage, the pump rotor is balanced at rotational speeds up to 8,000 rpm, where it behaves as a rigid body. The objective here is to compensate for both static and couple imbalances. In tests on this vibration-isolated stand, the system achieves residual vibration levels below 0.01 mm\/s RMS in the 3,500\u20138,000 rpm frequency range. This ultra-low reading is a stand-test result obtained under controlled conditions, not a typical field-measurement figure.<\/p>\n

Hatua ya 2 \u2013 Usawazishaji wa Rotori Nyumbuliku kwa Kasi ya Juu<\/h3>\n

Katika hatua ya pili, usawazishaji unafanywa kwa kasi ya uendeshaji ya rotori\u2014iwe rpm 42,000 au 60,000, kulingana na muundo wa pampu. Kwa kasi hii, rotori inaingia katika hali nyumbuliku na hupitia upotoshaji, ambao husababisha kutosawazika kwa dynamic zaidi. Urekebishaji wa mwisho huhesabiwa na kutumika kupunguza athari hizi. Kiwango cha mtetemo uliobaki baada ya usawazishaji wa kasi ya juu hakizidi 0.3 mm\/s RMS, kuhakikisha uendeshaji thabiti wa muda mrefu wa pampu.<\/p>\n

    Hitimisho<\/h2>\n

    Stendi ya usawazishaji wa kasi ya juu kwa rotori za pampu ya utupu inachanganya ugumu wa kimuundo, upimaji sahihi, na hesabu za hali ya juu. Inawezesha usawazishaji sahihi chini ya hali halisi za uendeshaji, iklipa fidia kwa kutosawazika kwa static na dynamic. Suluhisho hili linakidhi viwango vikali vya mtetemo na kuboresha kwa kiasi kikubwa uaminifu na maisha ya huduma ya mifumo ya pampu ya utupu ya kasi ya juu.<\/p>\n<\/div>\n<\/div><\/div><\/div><\/div><\/div>","protected":false},"excerpt":{"rendered":"
