Izixhobo zoomatshini be-excavator PC200-7 hydraulic pump solenoid valve 702-21-57400

Xa ipompo ye-hydraulic ye-excavator igugile kakhulu, inempembelelo ebulalayo kwi-excavator, ngoko ke iingxaki ezinjalo kufuneka zisonjululwe ngexesha. Ukugcinwa kwempompo ye-hydraulic ye-excavator ukusuka kula manqaku mathathu alandelayo ukufumana unobangela wokusilela:

(1) Jonga ukuvuza kwangaphakathi kwe-boom cylinder

Eyona ndlela ilula yokulungisa impompo ye-hydraulic ye-excavator kukunyusa i-boom kwaye ubone ukuba inokuwa okukhulu kwamahhala. Ukuba ukuhla kuyabonakala, susa isilinda ukuze ujonge, kwaye ubeke endaweni yesitywina ukuba igugile.

(2) Khangela ivalve yokulawula

Okokuqala ucoce ivalve yokhuseleko, khangela ukuba i-spool igugile, njengokunxiba kufuneka kutshintshwe. Ukuba akukho tshintsho emva kokufakwa kwevalve yokhuseleko, ke jonga ukunxiba kwe-spool yevalve yokulawula, umda wokucocwa ngokubanzi ngu-0.06MM, kwaye ukunxiba kufuneka kuthathelwe indawo.

(3) Ukulinganisa uxinzelelo lwempompo ye-hydraulic

Ukuba uxinzelelo luphantsi, luhlengahlengiswa, kwaye uxinzelelo alukalungiswanga, lubonisa ukuba ipompo ye-hydraulic igugile kakhulu.

Ngokubanzi, ezona zizathu ziphambili zokuba kutheni umthwalo webhanti le-boom ungaphakanyiswa zezi:

1. Impompo ye-hydraulic ye-excavator igugile kakhulu
Ukuvuza kwimpompo kunzulu ngesantya esiphantsi. Ngesantya esiphezulu, uxinzelelo lwempompo lunyuka kancane, kodwa ngenxa yokugqoka kunye nokuvuza kwangaphakathi kwempompo, ukusebenza kwe-volumetric kuncitshiswe kakhulu, kwaye kunzima ukufikelela kuxinzelelo olulinganisiweyo. Ipompo ye-hydraulic isebenza ixesha elide kwaye iqinisa ukunxiba, ubushushu be-oyile bukhuphuka, okukhokelela ekunxibeni kwamacandelo e-hydraulic kunye nokuguga kunye nomonakalo wamatywina, ukulahleka kobuchule bokutywina, ukuwohloka kweoyile ye-hydraulic, kwaye ekugqibeleni ukusilela.

I-2, ukukhethwa kwamacandelo e-hydraulic kungenangqiqo

Inkcazo ye-boom cylinder yi-70/40 i-non-standard series, kwaye izitywina nazo ziyinxalenye engeyiyo i-standard, ephezulu kwiindleko zokuvelisa kunye nokungahambi kakuhle ukubuyisela amatywina. I-diameter encinci ye-boom cylinder ibotshelelwe ukwenza inkqubo yokubeka uxinzelelo phezulu.
