S\u016bk\u0146a vibr\u0101cijas kontrole:<\/p>\n

1. Atsperu izolatoru uzst\u0101d\u012b\u0161ana:<\/p>\n

a. S\u016bk\u0146a atsperes izolatora stila izv\u0113le:<\/p>\n

Parasti tiek izv\u0113l\u0113ti br\u012bvi st\u0101vo\u0161i atsperu izolatori. To priek\u0161roc\u012bba ir vienk\u0101r\u0161a konstrukcija un zemas izmaksas. Atkl\u0101tas atsperes atvieglo past\u0101v\u012bgu to st\u0101vok\u013ca uzraudz\u012bbu un \u013cauj savlaic\u012bgi nomain\u012bt atsperes, lai nov\u0113rstu p\u0101rm\u0113r\u012bgu r\u016bs\u0113\u0161anu un boj\u0101jumus, kas var\u0113tu izrais\u012bt p\u0113k\u0161\u0146u s\u016bk\u0146a iegrim\u0161anu, potenci\u0101li boj\u0101jot iek\u0101rtu un p\u0101rraujot caurules.<\/p>\n

b. Pavasara izv\u0113le:<\/p>\n

Vibr\u0101cijas sl\u0101p\u0113t\u0101ju ra\u017eot\u0101ji parasti izv\u0113las atsperes, kas atbilst \u0161\u0101d\u0101m pras\u012bb\u0101m: Lai nodro\u0161in\u0101tu amortizatora stabilit\u0101ti, atsperes diametram j\u0101b\u016bt ne maz\u0101kam par 0,8 reiz\u0113m no t\u0101s augstuma pie nomin\u0101l\u0101s slodzes; atsperei j\u0101b\u016bt ar zin\u0101mu lieko g\u0101jienu, vismaz 50% no nomin\u0101l\u0101s statisk\u0101s deform\u0101cijas; un atsperes horizont\u0101lajai stingr\u012bbai j\u0101b\u016bt vismaz 100% no t\u0101s vertik\u0101l\u0101s stingr\u012bbas.<\/p>\n

c. Atsperes amortizatora novirzes izv\u0113le;<\/p>\n

Atsperes amortizatora nomin\u0101l\u0101 deform\u0101cija (nomin\u0101lais atsperes saspiede), ko parasti nodro\u0161ina amortizatoru ra\u017eot\u0101ji, ir 25 mm (no frekvences aptuveni 3-4 Hz). \u0160\u012b novirze ir pietiekama, lai izol\u0113tu 650 apgriezienu min\u016bt\u0113 str\u0101d\u0101jo\u0161a \u016bdens s\u016bk\u0146a vibr\u0101cijas. \u0100trumiem, kas ir maz\u0101ki par 650 apgr.\/min, ieteicams izmantot atsperu amortizatoru ar 40 mm vai maz\u0101ku deform\u0101ciju.<\/p>\n

2. Gumijas izolatoru uzst\u0101d\u012b\u0161ana:<\/p>\n

Gumijas izolatori parasti ir izgatavoti no hlorpr\u0113na kau\u010duka (CR) vai dabisk\u0101 kau\u010duka (NR). Parasti izmanto kompresijas tipa gumijas izolatorus, bet viegl\u0101kiem s\u016bk\u0146iem var izmantot b\u012bdes tipa gumijas izolatorus.<\/p>\n

Sal\u012bdzinot ar atsperu izolatoriem, gumijas izolatori nodro\u0161ina nedaudz zem\u0101ku vibr\u0101ciju izol\u0101cijas veiktsp\u0113ju.<\/p>\n

3. Uzst\u0101diet elast\u012bgu pamatni:<\/p>\n

Lai izpild\u012btu stingr\u0101kus vibr\u0101cijas kontroles standartus, lab\u0101kais risin\u0101jums neap\u0161aub\u0101mi ir elast\u012bga pamata uzst\u0101d\u012b\u0161ana kop\u0101 ar atsperu izolatoriem. Elast\u012bg\u0101 pamata specifik\u0101cijas: Pamatnes svaram j\u0101b\u016bt aptuveni 1-2 reizes liel\u0101kam par s\u016bk\u0146a svaru. R\u0101mim j\u0101b\u016bt konstru\u0113tam no sl\u0113gta kan\u0101ldzelzs, ar augstumu vismaz 1\/12 no pamatnes garuma, bet ne maz\u0101ku par 150 mm un ne liel\u0101ku par 300 mm. Garumam un platumam j\u0101b\u016bt pietiekamam, lai aptvertu visu s\u016bkni, ar 10-15 cm rezervi katr\u0101 pus\u0113. Ide\u0101l\u0101 gad\u012bjum\u0101 taj\u0101 b\u016btu j\u0101iek\u013cauj ar\u012b elkonis. Iek\u0161pus\u0113 j\u0101ielej betons, un tre\u0161da\u013c\u0101 augstuma j\u0101ievieto t\u0113rauda sieta sl\u0101nis. J\u0101uzst\u0101da atsperu izolatori, lai starp pamatu un pamatni b\u016btu 3-5 cm atstarpe.<\/p>\n

Abnormal pump vibration directly impacts safe operation. Severe vibration can cause certain components to deform or even break, severely shortening the pump’s service life. Vibration can also loosen bolts on rotating parts, potentially throwing mechanical components and endangering personnel. Pump vibration also generates noise, severely impacting the work environment.
