I-Excavator i-Hydraulic Pomp ye-Ocenoid Valve Expreliid Valve Iveli

I-Valveve yePhila yePhepha, uLawulo lweValve lunokwahlulwa kuba ziindidi ezimbini. Inye i-switch lolawulo, enye ilawulwa ngokuqhubekayo, i-servo ye-valve kunye nezinye iivalve zahlukile, ilahleko yamandla yamandla ingaphezulu, kuba ifuna ukuhamba okuthile ukugcina umsebenzi wesekethe yeoyile ye-oyile yangaphambi kokulawula. Inye i-switch yolawulo: nokuba ivulekile ngokupheleleyo okanye ivaliwe ngokupheleleyo, ireyithi yokuhamba iphezulu okanye ubuncinci, akukho veli ye-Electromagnetic, i-Electromagnetic Palve, i-electro-hydraulic reverve palve. Olunye lulawulo oluqhubekayo: I-Voveve Port inokuvulwa ngokweemfuno zawo nawuphi na umgangatho wokuvula, ngaloo ndlela ilawula ubungakanani bokuhamba, njengamantshontsho, njengamantshontsho alinganayo, i-valves.

Ulawulo oluzenzekelayo lunokwahlulwa kulawulo lwangaphakathi nolawulo oluqhubekayo. Ulawulo lwangaphakathi lutshintsho lokutshintsha. Kwinkqubo yolawulo lwe-pneumatic, ivalve evalelweyo ye-reverve ene-frequed esezantsi isetyenziselwa ukulawula indlela yegesi. Thentelela kwi-valve yokunciphisa ivalve yokulungisa uxinzelelo olufunekayo, exhomekeke kwivali yenkunkuma ukuze ihlengahlengise ukuhamba okufunekayo. Le nkqubo yolawulo lwe-pneumatic yemveli ifuna ukuba namandla amaninzi okuphumeza kunye nesantya esininzi sokunciphisa uxinzelelo, ifuna uxinzelelo oluninzi, ivumba leentsini kunye neevalves eziguqukayo. Ngale ndlela, hayi kuphela izinto ezifuna ngaphezulu, iindleko ziphezulu, ukwakhiwa kwenkqubo kubalulekile, kwaye uninzi lwamacandelo kufuneka luhlengahlengiswe kwangaphambili. Ulawulo lombane lwelvelo lombane lolawulo oluqhubekayo, olubonakaliswa lumanani obume bemveliso kunye nobungakanani bokufakelwa, kwaye kukho ubudlelwane obuthile bezinto eziphakathi kunye nobungakanani bokufakwa phakathi kunye nobungakanani bokufakelwa. Ulawulo olulinganayo luneloop evulekileyo umahluko phakathi kolawulo kunye nokuvalwa kwe-loop.
