Isebenza ku-excavator EX200-5 hydraulic relief valve 9134147

Lapho ingcindezi iguquguquka, izinyathelo ezihambisanayo kufanele zithathwe ngokuya ngezizathu ezilandelayo:

I-1) I-spool yokulawula ingcindezi entwasahlobo ithambile kakhulu noma igobile, ayikwazi ukugcina ingcindezi ezinzile, esikhundleni sentwasahlobo;

2) I-valve ye-cone noma ibhola lensimbi elinesihlalo se-valve alihambisani kahle, ukuvuza kwangaphakathi kukhulu futhi kuncane, okuholela ekucindezelweni okuphezulu nokuphansi, kufanele kulungiswe noma kushintshwe ukuze kuqinisekiswe uphawu oluhle;

I-3) Ukungcoliswa kwamafutha kuholela ekudakaleni okukhulu nokuncane ku-valve eyinhloko, okuholela ekushintshashintsheni kwengcindezi, imbobo eyinhloko yokuqeda i-valve kufanele ihlanzwe ngesikhathi, futhi uwoyela kufanele ushintshwe uma kunesidingo;

4) I-valve yesilayidi ayisebenzi, kufanele ilungise noma ishintshe i-valve yesilayidi;

5) Ivalvu ehlehlayo exhunywe ukude ivalvu yokukhulula ayilawuleki noma ukuvuza kukhulu noma kuncane, futhi ivalvu yokuhlehla kufanele ilungiswe noma ishintshwe ukuze kuqinisekiswe ukuthi uhlelo luvalwe kahle;

6. Uma ukuvuza kubi kakhulu, izinyathelo ezihambisanayo kufanele zithathwe ngokwalezi zizathu ezilandelayo:

1) Ukuvuza kwangaphakathi, okubonakala njengokuguquguquka kwengcindezi nokwanda komsindo;

2) Ngenxa yokugqoka noma ukungcola okubhajwe, i-valve yesigaxa noma ibhola lensimbi kanye nesihlalo se-valve akuhambisani, kufanele kuhlanzwe noma kushintshwe;

3) Igebe phakathi kwevalve yesilayidi nomzimba we-valve likhulu kakhulu, futhi i-spool ye-slide valve kufanele ishintshwe;

4) Ukuvuza kwangaphandle. Uma ipayipi elihlangene lixega noma livalwe kahle, qinisa isitaladi sepayipi bese ushintsha iringi yokuvala;

I-5) Uma uphawu endaweni ehlangene lumpofu noma lungavumelekile, indawo ehlangene kufanele ilungiswe futhi uphawu kufanele lushintshwe.
