Echilibrarea rotoarelor pompelor de vid asamblate<\/h3>\n

Introducere<\/h4>\n

La fabric\u0103, cu asisten\u021ba noastr\u0103, au fost dezvoltate \u0219i implementate standuri pentru echilibrarea rotoarelor asamblate din pompe de vid de mare vitez\u0103. Aceste rotoare trebuie s\u0103 \u00eendeplineasc\u0103 cerin\u021be stricte de calitate pentru echilibrare, respect\u00e2nd clasa 1 de precizie a echilibr\u0103rii conform GOST 22061-76, standardul sovietic privind calitatea echilibr\u0103rii (corespondentul s\u0103u interna\u021bional modern este ISO 21940-11, fostul ISO 1940-1), av\u00e2nd \u00een vedere c\u0103 frecven\u021ba lor de func\u021bionare este cuprins\u0103 \u00eentre 42,000 \u0219i 60,000 RPM.<\/p>\n

Proces tehnologic<\/h4>\n
    \n
  1. Prima etap\u0103<\/strong>: \u00cen aceast\u0103 etap\u0103, c\u00e2nd viteza de rota\u021bie a rotorului nu dep\u0103\u0219e\u0219te 8,000 RPM \u0219i rotorul r\u0103m\u00e2ne rigid, componentele principale ale dezechilibrelor de for\u021b\u0103 \u0219i de cuplu sunt compensate. Cu dispozitivele noastre, se ob\u021bine \u00een mod constant un nivel stabil al vibra\u021biilor reziduale sub 0.01 mm\/s \u00eentr-un interval de frecven\u021b\u0103 de 3,500 p\u00e2n\u0103 la 8,000 RPM (un rezultat al testului pe stand ob\u021binut pe acest stand dedicat, izolat la vibra\u021bii, nu o valoare tipic\u0103 de m\u0103surare \u00een teren).<\/li>\n
  2. A doua etap\u0103<\/strong>: Echilibrarea ulterioar\u0103 a rotorului se realizeaz\u0103 la frecven\u021ba de lucru, care poate ajunge la 42 000 sau 60 000 RPM, \u00een func\u021bie de designul pompei. La aceast\u0103 frecven\u021b\u0103, care dep\u0103\u0219e\u0219te viteza critic\u0103 de rota\u021bie, rotorul devine flexibil \u0219i se deformeaz\u0103, necesit\u00e2nd m\u0103suri suplimentare de echilibrare.<\/li>\n<\/ol>\n

    Rezultate<\/h4>\n

    Vibra\u021bia rezidual\u0103 a rotorului, ob\u021binut\u0103 \u00een cele din urm\u0103 \u00een etapa a doua, nu dep\u0103\u0219e\u0219te 0,3 mm\/s. Acest lucru asigur\u0103 o perioad\u0103 lung\u0103 de func\u021bionare f\u0103r\u0103 probleme pentru aceast\u0103 component\u0103 critic\u0103. Timpul total pentru procesul de echilibrare a acestui produs unic nu dep\u0103\u0219e\u0219te, de obicei, 30 de minute.<\/p>\n

    Eficien\u021ba economic\u0103<\/h4>\n

    Costul pentru unul dintre standurile de echilibrare, echipat cu dispozitivul nostru de echilibrare, a fost de numai 3 000 USD pentru client. Aceasta reprezint\u0103 de aproximativ 10 ori mai pu\u021bin dec\u00e2t costul unei alternative importate propuse.<\/p>\n<\/div>\n<\/div><\/div><\/div><\/div><\/div>","protected":false},"excerpt":{"rendered":"

    Introduction At the factory, with our assistance, stands have been developed and implemented for the balancing of assembled rotors in high-speed vacuum pumps. These rotors must meet stringent quality requirements for balancing, adhering to Class 1 balancing accuracy as per GOST 22061-76, the Soviet balance quality standard (its modern international […]<\/p>\n","protected":false},"author":2,"featured_media":1117,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"ai_generated_summary":"","footnotes":""},"categories":[4,5],"tags":[],"class_list":["post-1120","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-example","category-solutions"],"_links":{"self":[{"href":"https:\/\/vibromera.eu\/ro\/wp-json\/wp\/v2\/posts\/1120","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/vibromera.eu\/ro\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/vibromera.eu\/ro\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/vibromera.eu\/ro\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/vibromera.eu\/ro\/wp-json\/wp\/v2\/comments?post=1120"}],"version-history":[{"count":0,"href":"https:\/\/vibromera.eu\/ro\/wp-json\/wp\/v2\/posts\/1120\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/vibromera.eu\/ro\/wp-json\/wp\/v2\/media\/1117"}],"wp:attachment":[{"href":"https:\/\/vibromera.eu\/ro\/wp-json\/wp\/v2\/media?parent=1120"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/vibromera.eu\/ro\/wp-json\/wp\/v2\/categories?post=1120"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/vibromera.eu\/ro\/wp-json\/wp\/v2\/tags?post=1120"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
