I-Hydraulic pilot yohlobo lwevalve yendlela enye yokukhulula i-FN15-01 ye-crane

1) Ukusebenza ngokuvulwa okukhulu ukwandisa ubomi.

Vumela ivalve elawulayo ivuleke ibe nkulu kangangoko ukususela ekuqaleni, yithi i-90%. Ngaloo ndlela, i-cavitation, i-abrasion kunye nezinye iziphumo ziveliswa phezulu kwi-core valve. Ngokutshatyalaliswa kwesiseko se-valve kunye nokunyuka kokuhamba okupheleleyo, i-valve ehambelanayo kufuneka ivalwe kancinci, eya kuqhubeka ichithwa kwaye ivalwe ngokuthe ngcembe, ukwenzela ukuba zonke ii-valve cores zingasetyenziswa ngokuguquguqukayo. Ngelo xesha, i-gap ye-valve ye-throttle inkulu kwaye i-abrasion ibuthathaka xa isebenza kunye nokuvuleka okukhulu, okungaphezulu kwe-1 ~ 5 ixesha elide kunoko xa i-valve iqhutywe ngokuvula okuphakathi kunye nokuvulwa okuncinci. Isiqalo.

2) Kumsebenzi wokwandisa

ukuhla koxinzelelo kudliwe ngokubeka i-valve yokupakisha i-valve emva kokuvula i-valve ukuphucula kakhulu ubomi benkonzo; Cima ivalve yesandla eqhagamshelwe kuthotho kumbhobho de ivalve elawulayo ifumane idigri yokuvula esebenzayo. Kulula kakhulu, kulula kwaye kunengqiqo kubavelisi bevalve yoncedo lomqhubi ukukhetha le ndlela xa ivalve ivula kancinci ekuqaleni.

3) indlela yokuphucula kakhulu ubomi benkonzo ngokunciphisa ukucaciswa kunye nokwandisa umsebenzi

Ngokweenkcukacha zokunciphisa i-valve yokulawula, ukuvulwa komsebenzi kwandiswa. Amanyathelo athile alandelayo: buyisela ivalve encinci kunye nobukhulu obunye, ukuba i-DN25 isetyenziselwa ukutshintsha i-DN32; Umzimba wevalve awutshintshanga, kwaye isitulo sevalve esinendawo yesitulo esincinci siyatshintshwa.

4) indlela yokuhambisa iindawo ezonakalisiweyo ukuphucula ubomi benkonzo

Hambisa indawo eyonakele kakhulu kwindawo yokuqala kunye neyesibini ukugcina umphezulu wokutywina kunye nomphezulu we-throttle yesihlalo esingundoqo sevalve.
