Isebenza kwi-excavator EX200-5 hydraulic relief valve 9134147

Xa uxinzelelo luguquguquka, amanyathelo ahambelanayo kufuneka athathwe ngokwezi zizathu zilandelayo:

I-1) Ulawulo loxinzelelo lwe-spool spring luthambile kakhulu okanye lugobile, alukwazi ukugcina uxinzelelo oluzinzileyo, lutshintshe intwasahlobo;

2) I-valve ye-cone okanye ibhola yensimbi enesihlalo se-valve ayihambelani kakuhle, ukuvuza kwangaphakathi kukhulu kwaye kuncinci, okubangelwa uxinzelelo oluphezulu kunye oluphantsi, kufuneka lulungiswe okanye lutshintshwe ukuze kuqinisekiswe ukutywinwa okulungileyo;

I-3) Ungcoliseko lwe-oyile lukhokelela ekudakaleni okukhulu kunye nokuncinci kwi-valve engundoqo, okubangelwa ukuguquguquka koxinzelelo, umngxuma ongundoqo wokudambisa i-valve kufuneka ucocwe ngexesha, kwaye ioli kufuneka itshintshwe xa kuyimfuneko;

4) Ivalve yesilayidi ayisebenzi, kufuneka ilungise okanye ibuyisele ivalve yesilayidi;

5) Ivalve yokubuyisela umva edityaniswe kude nevalve yokukhulula ayilawuleki okanye ukuvuza kukhulu okanye kuncinci, kwaye ivalve yokubuyisela umva kufuneka ilungiswe okanye itshintshwe ukuze kuqinisekiswe ukuba inkqubo ivalwe kakuhle;

6. Ukuba ukuvuza kuyingozi kakhulu, amanyathelo ahambelanayo kufuneka athathwe ngokwezi zizathu zilandelayo:

I-1) Ukuvuza kwangaphakathi, kubonakaliswe njengokuguquguquka koxinzelelo kunye nokunyuka kwengxolo;

2) Ngenxa yokugqoka okanye ukungcola, i-valve ye-cone okanye ibhola yensimbi kunye nesihlalo se-valve asihambelani, kufuneka sicocwe okanye sitshintshwe;

3) Umsantsa phakathi kwevalve yesilayidi kunye nomzimba wevalve mkhulu kakhulu, kwaye i-spool yevalve yesilayidi kufuneka itshintshwe;

4) Ukuvuza kwangaphandle. Ukuba umdibaniso wombhobho ukhululekile okanye uvalwe kakubi, qinisa isitalato sombhobho kwaye ubeke endaweni yomsesane wokutywina;

5) Ukuba isitywina kwindawo edibeneyo ihlwempuzekileyo okanye ayivumelekile, indawo edibeneyo kufuneka ilungiswe kwaye isitywina kufuneka sitshintshwe.
