Tes nres valve yog dab tsi?

1.Dab tsi yog tes nres valve
Lub tes tswj valve yog cov cuab yeej tseem ceeb ntawm chaw nres tsheb, nres nres thiab nres nres hauv cov txheej txheem ntawm kev pabcuam tsheb nres.
Lub nres nres ntawm lub tsheb tau tso tawm tag nrho thiab lub tsheb khiav hauv lub xeev;Thaum tus kov nyob rau hauv qhov chaw xauv, lub tsheb ciav hlau nyob rau hauv tag nrho lub xeev braking;Thaum tus kov nyob rau hauv qhov chaw kuaj xyuas, qhov nres nres ntawm lub tsheb laij teb yog nyob rau hauv lub xeev braking, tab sis lub trailer yog nyob rau hauv tag nrho tso tawm braking xeev.
Thaum tus kov txav, tus kov lub cam thawb lub piston loj downwards, nias lub caij nplooj ntoos hlav tshuav, thawb lub piston downwards, kaw lub tso pa valve, qhib tag nrho lub inlet valve ntawm lub valve ntxiv, thiab cov cua compressed nyob rau hauv cov kab noj hniav nkag mus rau hauv cov kab noj hniav. , thiab ces muab faib ua ob txoj kev.Ib txoj kev nkag mus rau lub caij nplooj ntoos hlav nres chamber los ntawm lub qhov ncauj kom tso lub nres nres ntawm lub tsheb laij teb;Nkag mus rau lub trailer nres valve los ntawm qhov chaw nres nkoj kom tso lub trailer nres nres.Thaum tus kov nyob hauv qhov ntau, qhov nres nres ntawm lub tsheb tau tso tawm tag nrho.
2.Function ntawm phau ntawv tswj valve
Lub cav braking yog nres nres.Rau cov tsheb hnyav, braking feem ntau suav nrog kev pabcuam braking;Chaw nres tsheb, nres nres, nres nres.Qhov kev pabcuam nres tau pom tau los ntawm ob chav chamber nres tus tswv valve, nres nres nres thiab nres nres nres tau pom los ntawm phau ntawv tswj lub valve, thiab cov pa nres nres tau pom los ntawm qhov tso pa tawm npauj npaim valve.Lub qhov hluav taws xob nres npauj npaim valve yog ntsia tom qab lub qhov tso pa ntawm lub cav.Thaum lub laub khawm valve ua haujlwm, cov cua siab dhau los ntawm lub tog raj kheej ua haujlwm ntawm lub tog raj kheej lub tog raj kheej kom ua rau lub tshuab cua piston hauv lub tog raj kheej ua haujlwm, yog li tsav tus pas nrig tig lub npauj npaim valve disc 90 degrees, kaw qhov tso pa tawm. hose, ua rau lub cav tso tawm thaiv.Thaum lub cav tso tawm yog thaiv, lub piston hauv lub tog raj kheej tsis tuaj yeem taug kev ib txwm, thiab nws yuav tsum tiv thaiv qhov kev tiv thaiv no, nyob rau hauv txoj kev no, nyob rau hauv cov nyhuv ntawm huab cua tsis kam, qhov kev txiav txim ntawm lub cav piston yuav raug txo.Vim yog lub zog traction, lub tsheb ceev yuav qeeb.
3.Common faults ntawm nws pib phau ntawv tswj valve
3-1 Thaum tus kov txav, lub piston loj, sib npaug lub caij nplooj ntoos hlav thiab tshuav piston txav mus rau sab saud, lub qhov tso pa tawm qhib thiab lub valve kaw;Lub inlet valve ntawm qhov ntxiv valve raug kaw.Qhov tso zis cua siab P, I “22 txo qis linearly mus rau xoom thaum lub kaum sab xis nce.
3-2 Thaum tus kov yog los ntawm 730 mus rau 820, cua inlet valve 6 ntawm lub valve ntxiv yog qhib, thiab cov nyhuv braking ntawm lub trailer raug tso tawm.
3-3 Xyuas seb lub tsheb puas tuaj yeem nres ntawm qhov chaw nres tsheb tsuas yog nyob rau hauv qhov nres nres ntawm lub tsheb laij teb.Thaum tus kov raug tso tawm, tus kov yeej rov qab mus rau qhov chaw nres tsheb nres nres.
3-4 Cov khoom puas tuaj yeem kuaj xyuas thiab hloov los ntawm lub cev qis thiab nruab nrab lub cev.
3-4 Yog hais tias muaj sundries nyob rau hauv lub phau ntawv tswj valve, lub O-ring puas lawm, lub piston yog hnav, lub puab kab noj hniav los yog ib feem yog jammed los yog jammed, lub zoo braking nyhuv yuav ua tsis tau.
3-5 Kev daws teeb meem:
1.(1) Tshem tawm cov bolts ntawm qis kawg npog ntawm phau ntawv tswj valve, tshem tawm lub piston nyob rau hauv lub chamber sab hauv, xyuas, ntxuav thiab ua ib tug tsim nyog los ua ke.
2.(2) Qhov kev txwv siv ntawm phau ntawv tswj valve yog li 50000 km.Nws yuav tsum tau disassembled rau "kev tshuaj ntsuam xyuas" thiab nruab nrog cov khoom siv kho tshwj xeeb los muab cov xwm txheej yooj yim rau kev saib xyuas
4. Muaj nuj nqi ntawm phau ntawv tswj valve
Cov phau ntawv tswj valve txuas nrog lub qhov rooj hloov hauv lub cab.Lub zog ntawm lub spool valve nyob rau hauv lub valve lub cev yog tswj manually tswj kev hloov dua siab tshiab ntawm hydraulic roj.Lub ntsiab roj siab yog nkag mus rau hauv phau ntawv tswj valve, thiab cov roj siab ntawm cov roj hluav taws xob tseem ceeb yog nkag mus rau cov roj hluav taws xob sib txuas hauv kev ua haujlwm sib txawv los ntawm kev txav ntawm lub swb valve.
5. Kev ceev valve interface
Kev tswj ib feem ntawm lub lifting valve rau lub hnab plua plav tshem tawm yog tsim los ntawm huab cua lub tog raj kheej, electromagnetic reversing valve, valve phaj thiab lifting pas nrig.
Thaum qhov kev txwv hloov pauv yuav tsum tau, qhov kev hloov pauv tuaj yeem raug ntxiv, thiab cov hlau nplaum hloov ntawm lub tog raj kheej tuaj yeem siv rau kev txwv tsis pub.General bypass valve muaj kev tshawb nrhiav kev mus ncig.
Ntawm kev tswj hluav taws xob, tsuas yog ib qho kev tswj xyuas kab yog siv los tswj lub solenoid reversing valve.Tus naj npawb ntawm cov kab yog txiav txim siab raws li qhov xaiv rov qab valve.
teeb meem xav tau kev saib xyuas:
Hauv qee qhov chaw, vim qhov ntsuas kub, lub poppet valve tuaj yeem xaiv lub valve tsis siv lub tog raj kheej.Feem ntau poppet li qub yog tswj los ntawm lub tog raj kheej cua.
Peb muaj tus lej Valve raws li hauv qab no:
