Ivalve yeekhatriji zemisonto XYF10-06 kumatshini wokwakha wecrane

Oonobangela abasisiseko bengxolo kunye nokungcangcazela

1 Ingxolo eyenziwa yimingxuma

Xa umoya ufunxwa kwi-oyile ngezizathu ezahlukahlukeneyo, okanye xa uxinzelelo lwe-oyile lungaphantsi kunoxinzelelo lwe-atmospheric, umoya othile onyityilisiweyo kwi-oyile uya kunyuka wenze amaqamza. La maqamza makhulu kwindawo yoxinzelelo oluphantsi, kwaye xa ehamba ngeoyile ukuya kwindawo yoxinzelelo oluphezulu, axinzelelwe, kwaye ivolumu ngokukhawuleza iba yincinci okanye amaqamza ayanyamalala. Ngokuchasene noko, ukuba ivolumu ekuqaleni yayincinci kwindawo yoxinzelelo oluphezulu, kodwa ngokukhawuleza inyuka xa igeleza kwindawo yoxinzelelo oluphantsi, umthamo we-bubbles kwioli utshintsha ngokukhawuleza. Ukutshintsha ngokukhawuleza umthamo we-bubble kuya kuvelisa ingxolo, kwaye ngenxa yokuba le nkqubo yenzeka ngephanyazo, iya kubangela impembelelo ye-hydraulic yendawo kunye nokungcangcazela. Isantya kunye noxinzelelo lwe-valve ye-pilot port kunye ne-valve ye-valve enkulu ye-valve yokukhulula i-pilot iyahluka kakhulu, kwaye i-cavitation kulula ukwenzeka, okubangela ingxolo kunye nokungcangcazela.

2 Ingxolo eyenziwa yimpembelelo yehydraulic

Xa i-valve yokunceda i-pilot ithotywa, ingxolo yempembelelo yoxinzelelo iya kwenzeka ngenxa yokuhla ngokukhawuleza koxinzelelo kwisekethe ye-hydraulic. Uxinzelelo oluphezulu kunye neemeko zokusebenza ezinkulu, ingxolo enkulu yempembelelo, ebangelwa ixesha elifutshane lokukhulula i-valve yokuphuphuma kunye nefuthe le-hydraulic. Ngethuba lokukhulula, uxinzelelo lutshintsha ngokukhawuleza ngenxa yokutshintsha ngokukhawuleza kwesantya seoli, okubangelwa yimpembelelo yamaza oxinzelelo. I-Pressure Wave yi-wave shock encinci, eyenza ingxolo encinci, kodwa xa idluliselwe kwisistim ngeoyile, ukuba ihambelana nayo nayiphi na indawo yomatshini, inokunyusa ukungcangcazela kunye nengxolo. Ngoko ke, xa ingxolo yempembelelo ye-hydraulic isenzeka, idla ngokukhatshwa yinkqubo yokungcangcazela.

Iimfuno eziphambili zevalve yokukhulula zezi: uluhlu olukhulu lokulawula uxinzelelo, ukutenxa kokulawula uxinzelelo oluncinci, ukujika koxinzelelo oluncinci, isenzo esibuthathaka, umthamo omkhulu wokulayisha kunye nengxolo ephantsi.
