Koj yuav ua li cas yog tias koj lub excavator tsis tig? Qee cov neeg ua haujlwm tsim kho tau nug kuv cov lus nug no, yog li kuv tsis siv sijhawm los txheeb xyuas cov kev daws teeb meem no thiab suav nrog 10 yam hauv qab no:
Tshawb xyuas lub excavator accessory siab sensor, uas nyob ib sab ntawm lub rotary valve core ntawm ntau txoj kev valve. Hloov nws ncaj qha yog tias puas.
Khaws lub excavator nyob rau hauv tag nrho rotary stroke thiab high-throttle mob, ces ntsuas yog hais tias lub rotary tsav siab nyob rau hauv 3.0MPa. Yog tias tsis yog, xyuas seb tus tsav valve tseem ceeb ntawm cov khoom siv excavator puas hnav lossis puas.
Tshawb xyuas seb lub ntsuas hluav taws xob teb thiab lub teb P / B solenoid valve puas ua haujlwm zoo.
Tshawb xyuas qhov luv luv ib feem ntawm lub shuttle valve core ntawm anti-reversal valve thiab lub qhov throttle rau impurities. Tshawb xyuas qhov ntev shuttle ntawm lub valve core cover rau qhov txawv txav; ntxuav lossis hloov cov khoom yog tias tsim nyog.
Paub meej tias lub siab ntawm P2 twj tso kua mis siab sensor yog nyob rau hauv 10.0-15.0MPa thaum lub excavator nyob rau hauv tag nrho rotary stroke thiab thaum lub sij hawm ua hauj lwm.
Xyuas seb qhov tseem ceeb tam sim no thiab cov kev kub ntxhov siab ntawm P2 unloading proportional valve thiab P2 twj proportional valve (excavator accessories) yog qhov qub.
Tshawb xyuas tus nqi tam sim no thiab theem nrab siab ntawm kev mus los ncaj proportional valve. Thaum lub throttle siab (tsis hais qhov nruab nrab / kev ua haujlwm),
ua ib tug standalone rotary tsab ntawv tsa suab los xyuas kom meej tias qhov thib ob siab ntawm kev mus los ncaj proportional valve yog qis dua 0.8MPa. Yog tias tsis yog, hloov lub valve proportional (excavator accessory).
Txheeb xyuas qhov ncaj nraim valve core thiab rotary valve core ntawm ntau txoj kev valve rau hnav, thiab tshuaj xyuas seb lawv cov springs puas lawm.
Thaum lub excavator nyob rau hauv tag nrho cov kab mob stroke thiab nyob rau hauv cov dej ntws, xyuas seb lub siab ntawm lub rotary nyem valve yog 3MPa.
Tshem tawm ib qho me me ntawm cov roj iav los ntawm cov roj ntws qhov chaw nres nkoj ntawm lub rotary reducer thiab xyuas cov khoom hlau. Tshawb xyuas cov khoom siv sab hauv ntawm lub tshuab hluav taws xob (excavator accessories) rau hnav, thiab xyuas cov iav reducer rau qhov txawv txav thiab cov chips.
