Iingongoma zokuqwalaselwa
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.
