Kuba John Deere ivelufa solenoid AL177192 Ukwakhiwa koomatshini izincedisi Excavator

Ivalve ye-solenoid elinganayo luhlobo olukhethekileyo lwevalve ye-solenoid ebonelela ngokugudileyo

kunye notshintsho oluqhubekayo lokuhamba okanye uxinzelelo kuxhomekeke kwigalelo lombane. Olu hlobo lunako

zihlelwe njengevalve yokulawula. Ukuze ivalve ye-solenoid ilingane, i-plunger

indawo kufuneka ilawulwe. Iphunyezwa ngokulinganisa iplunger ngamandla angaphandle

ngokuqhelekileyo kwenziwa yintwasahlobo. Intwasahlobo iya kucinezela de amandla angaphandle alingane ne-electromagnetic

amandla e-solenoid. Ukuba indawo yeplunger kufuneka ilawulwe, okwangoku kufuneka kutshintshwe,

okubangela ukungalingani kwamandla entwasahlobo. Intwasahlobo iya kucinezela okanye yolule kude kube namandla

bi-alance imiselwe.

             Enye ingxaki yolu hlobo yimpembelelo ye-friction. I-friction iphazamisa ibhalansi egudileyo

phakathi kwe-electromagnetic and spring forces. Ukuphelisa esi siphumo, ulawulo olukhethekileyo lwe-elektroniki

zisetyenziswa. Indlela eqhelekileyo esetyenziselwa iimpawu zokulawula ngokulinganayo iivalvu ze-solenoid

kukumodareyitha kobubanzi be-pulse okanye i-PWM. Ukusebenzisa isignali ye-PWM njengoko igalelo lolawulo libangela i-solenoid

ukuvula nokuvala ngokuqhubekayo ngesantya esikhawulezayo. Oku kubeka i-plunger kwindawo ejikelezayo kwaye

ukuze ibe kwindawo ezinzileyo. Ukutshintsha indawo yeplunger. Imeko yokuvula nangaphandle kwe-solenoid,

okwaziwa ngokuba ngumjikelo womsebenzi, uyalawulwa.

              Ngokungafaniyo neevalvu eziqhelekileyo zokuvula/ukuvala i-solenoid, iivalvu ze-solenoid ezilinganayo zisetyenziswa kwizicelo

ezifuna ulawulo lokuqukuqela oluzenzekelayo, njengee-proportional pneumatic actuators, ivalve yokuthomalalisa, isitshisi

ulawulo, njl.
