Ma hydraulic balance valve Excavator hydraulic cylinder spool CXHA-XBN

Kapangidwe ka valve ndi mfundo yogwirira ntchito

Valve ya hydraulic balance valve imalola kuti mafuta aziyenda momasuka kuchokera ku doko 2 kupita ku doko 1. Titha kuwona kuchokera pazithunzi zomwe zili pamwamba pa chithunzi chomwe chili pansipa kuti pamene mphamvu ya mafuta ya doko 2 ili pamwamba kuposa ya doko 1, spool ya gawo lobiriwira limasunthira ku doko 1 pansi pa kuthamanga kwamadzimadzi, ndipo valavu yowunikira imatsegulidwa, ndipo mafuta amatha kuyenda momasuka kuchokera ku doko 2 kupita ku doko 1.

Kuthamanga kuchokera ku doko 1 kupita ku doko la 2 kumatsekedwa mpaka kukakamizidwa kwa doko loyendetsa ndege kufika pamtengo wina ndipo buluu la buluu limasunthidwa kumanzere kuti litsegule khomo la valve kuti mafuta aziyenda kuchokera ku doko 1 kupita ku doko 2.

Doko limatseka pamene kuthamanga kwa woyendetsa sikukwanira kutsegula spool ya buluu. Kuthamanga kuchokera ku doko 1 kupita ku doko 2 kwadulidwa.
Mfundo yogwira ntchito ya hydraulic balance valve:
Kusanja kuzungulira ndi valavu yotsatizana ya unidirectional. Sinthani valavu yotsatizana kuti chotulukapo cha kuthamanga kwake kotsegulira ndi malo ochitirako chipinda chapansi pa silinda ya hydraulic cylinder ndi yayikulu pang'ono kuposa mphamvu yokoka ya magawo osunthika. Pamene pisitoni imatsikira pansi, chifukwa pali kukakamizidwa kwina kwa kumbuyo kwa kayendedwe ka mafuta kuti athandizire mphamvu yokoka, pisitoni idzagwa bwino pokhapokha pamene kumtunda kwa pistoni kuli ndi mphamvu inayake; Pamene valavu yobwerera ili pakati, pisitoni imasiya kusuntha ndipo sichipitirira pansi. Valve yotsatizana pano imatchedwanso valve balance. Muzitsulo zotsatizanazi, valavu yotsatizana imasinthidwa pambuyo pa kupanikizika. Ngati ntchitoyo ikucheperachepera. Kuthamanga kwa pampu kuyenera kuwonjezereka, zomwe zidzawonjezera kutaya mphamvu kwa dongosolo. Chifukwa cha kutayikira kwamkati kwa valve yotsatizana ndi valavu yobwerera kumbuyo kwa mawonekedwe a slide valve, zimakhala zovuta kuti pisitoni iyime mokhazikika pamalo aliwonse kwa nthawi yayitali, zomwe zingapangitse kuti chipangizo cha mphamvu yokoka chiwonongeke. Chifukwa chake, derali ndiloyenera kuti ntchitoyo ikhale yokhazikika ndipo zofunikira za hydraulic cylinder piston locking sizili zapamwamba.
