I-excavator hydraulic pump solenoid valve proportional solenoid valve TM68301

Ivalve elinganayo, ulawulo lokuhamba kwevalve lunokwahlulwa lube ziindidi ezimbini. Enye i-switch control, enye ilawula ngokuqhubekayo, i-valve ye-servo kunye nezinye iivalve zihluke, ilahleko yayo yamandla inkulu, kuba idinga ukuhamba okuthile ukuze kugcinwe umsebenzi wesiphaluka sokulawula i-oyile yangaphambili. Olunye lulawulo lokutshintsha: nokuba luvuleke ngokupheleleyo okanye luvalwe ngokupheleleyo, umlinganiselo wokuhamba ungowona uphezulu okanye ubuncinci, akukho mbuso uphakathi, njengombane oqhelekileyo we-electromagnetic ngokusebenzisa ivalve, ivalve yokubuyisela umbane ye-electromagnetic, ivalve ye-electro-hydraulic reversing valve. Olunye lulawulo oluqhubekayo: i-valve port inokuvulwa ngokwesidingo salo naliphi na iqondo lokuvula, ngaloo ndlela ilawula ubungakanani bokuqukuqela, iivalvu ezinjalo zinolawulo lwezandla, olufana ne-throttle valves, kodwa zilawulwa nge-elektroniki, ezifana nokulinganisa. iivalve, iivalve zeservo.

Ulawulo oluzenzekelayo lunokwahlulwa lube lulawulo lwethutyana kunye nolawulo oluqhubekayo. Ulawulo lwethutyana lulawulo lokutshintsha. Kwinkqubo yokulawula i-pneumatic, i-valve yokubuyisela i-ON-OFF ene-frequency ephantsi yokusebenza isetyenziselwa ukulawula ukuphuma kwendlela yegesi. Thembela kwi-valve yokunciphisa uxinzelelo ukulungelelanisa uxinzelelo olufunekayo, uthembele kwi-valve ye-throttle ukulungelelanisa ukuhamba okufunekayo. Le nkqubo yokulawula umoya wendabuko ifuna ukuba nezixhobo ezininzi zokukhupha kunye nezantya zokushukuma ezininzi, idinga iivalve zokunciphisa uxinzelelo oluninzi, i-throttle valves kunye ne-valve yokubuyisela umva. Ngale ndlela, kungekhona kuphela amacandelo adinga ngaphezulu, ixabiso liphezulu, ukubunjwa kwenkqubo kuyinkimbinkimbi, kwaye amaninzi amacandelo kufuneka alungiswe ngesandla kwangaphambili. Ulawulo lwevalvu elinganayo yombane lololawulo oluqhubekayo, oluphawulwa lutshintsho lwesixa semveliso kunye nobungakanani begalelo, kwaye kukho unxulumano oluthile lolungelelwaniso phakathi kobuninzi bemveliso kunye nobungakanani begalelo. Ulawulo olulinganayo lune-loop evulekileyo Umahluko phakathi kolawulo kunye nolawulo oluvaliweyo.
