Diesel engine self-priming pumps can be divided into two types: one is the diesel engine self-priming pump set based on the ZW self-priming sewage pump, and the other is the diesel engine pump set system based on the new type strong self-priming pump and the added vacuum assistance device. Qhov sib txawv ntawm ob lub diesel cav tus kheej- Presing twj tau nyiaj muaj qhov siab yuav tus kheej, tus kheej}}}}}. Cov hom tshiab diesel cav tshuab tus kheej- Prosed twj muaj qhov kom zoo dua {13} Pab tus kheej qhov siab. Lub valve qia tuaj yeem ncav cuag 8-9 meters, lub sijhawm hluav taws xob nrawm, qhov khiav txaus yog dav, thiab tus nqi Flow Flow tau ncav cuag 2600 cubic meters ib teev.
Lub tshuab nqus tsev kev pab ntawm cov diesel cav tus kheej - Presing twj siv lub tshuab nqus plua plav raws lub zog ntawm lub zog ntawm cov ncej roj diesel. Cov PULLEY tsav lub tshuab nqus tsev thiab ua haujlwm ua ke nrog tus diesel cav tus kheej- Presh} Presh prement twj tso kua mis, thiab tag nrho cov kab ke ib txwm nyob hauv lub tsev nqus nqus lub xeev. Kev ua yeeb yam ntawm tus kheej- Prosed twj yog ruaj khov, thiab lub tshuab nqus} {nres tus kheej {}} pre} priming twj.
Lwm hom diesel cav tus kheej - Preading twj yog lub tshuab nqus tsev {{} pab tau cov txheej txheem uas tuaj yeem nres. Thaum lub tshuab nqus plua plav dej, lub tshuab nqus tsev cia nres nres ntawm lub clutch. Tus nqi ntawm diesel cav tus kheej- prease nyuj yog tus kheej. Ob lub tshuab nqus tsev {-} pab tau diesel tshuab yog tus kheej- priming hom. Nqus twj tso kua mis muaj tib tus kheej - Pre} Priming kev ua tau zoo.
Diesel cav tus kheej - Presing twj muaj peev xwm nqus tau rau hauv thiab cov kua dej loj thiab cov roj muaj fiber ntau. Tshwj xeeb tshaj yog cov impeller ntawm hom tshiab diesel cav nqus dag zog, thiab tus kheej} Pronic} Presh priming twj tso kua mis muaj lub peev xwm tseem ceeb dua rau hauv cov lus.
Diesel tus kheej - Presing twj tuaj yeem yog cov qauv dej phwj tuaj,}}}}}}}}}} kev txuag dej siab, thiab yooj yim siv thiab tswj hwm. Lawv tuaj yeem tsim qauv nrog cov qauv sib dhos.
Diesel cav tus kheej - Presing twj yog raws li lub ntsiab lus uas lub cav diesel muab lub zog rau lub twj tso ua haujlwm. Tam sim no, lawv tau siv dav hauv kev tiv thaiv hluav taws, kev tiv thaiv ib puag ncig, kev lag luam tshuaj, kev lag luam hluav taws xob, kev tsim kho kev ua liajctse, tsim kho, thiab lwm yam.
1. Taw qhia rau Diesel Cav Self - Pre preem twj tso kua mis
Ua ntej pib lub diesel cav tus kheej - Presing twj tso kua mis, tsis tas yuav sau nws nrog dej (nws tseem yuav tau sau tom qab thawj zaug). Tom qab luv - kev ua haujlwm, raws li txoj haujlwm ntawm diesel cav tus kheej- Preading thiab muab tso rau hauv kev ua haujlwm ib txwm muaj.
Lub cav diesel lub cav - Preading twj tso kua zaub muaj cov qauv kev tshawb fawb txuj ci zoo. Lub twj tso kua mis chamber ntawm diesel cav tus kheej- Prosed chamber yog cov kua tshuaj kos duab, ib qho kua rov qab kos duab, ib lub roj sib cais chav thiab lub qhov rov qab. Tsuas yog yuav tsum tau sau nws ua ntej thawj zaug pib, thiab tsis tas yuav rov qab ua qhov txhaws tom qab ntawd.
2. Pib thiab kev ua haujlwm ntawm Diesel Cav Self - pre} prease twj tso kua mis
(1) Thaum pib tus diesel cav tus kheej- Pre} Pronice} Presh prement twj tso kua mis, xyuam xim rau seb qhov kev sib hloov ntawm kev sib hloov ntawm lub twj tso kua mis yog qhov tseeb.
(2) Thaum lub sijhawm sib hloov, xyuam xim rau cov suab tsis zoo thiab kev co ntawm cov diesel cav tus kheej- pre} priming twj tso kua mis.
(3) Ua tib zoo mloog rau kev nyeem ntawm lub siab ntawm lub siab thiab lub tshuab nqus tsev. Tom qab pib, thaum kev nyeem ntawm lub siab ntsuas thiab nqus nqus hluav taws xob rau lub sijhawm thiab tom qab ntawd ruaj khov, nws qhia tau tias cov twj siv roj thiab tau nkag mus rau lub sijhawm ua haujlwm ua haujlwm.
(4) Ua ntej Diesel Cav Self- Preading twj ua haujlwm tau ua lag luam, tshwj xeeb saib xyuas tus txheej txheem ua haujlwm Yog tias cov txheej txheem ntev dhau thiab cov dej kub nyob rau hauv lub twj tso kua mis tau siab dhau,}} Prosed twj tso kua mis {4 hauv cov yeeb nkab paug tuaj yeem thim rov qab. Cov kua muaj peev xwm txuas tau ncaj qha ntxiv rau lub twj tso kua mis. Txias cov kua hauv lub twj tso kua mis thiab tom qab ntawd pib.
(5) Yog hais tias cov kua kub hauv lub tshuab diesel lub tshuab tus kheej {1} Tam sim no yog qhov nyuaj, thiab cov kua hauv cov yeeb nkab paug tuaj yeem thim rov qab. Cov kua muaj peev xwm txuas tau ncaj qha ntxiv rau lub twj tso kua mis. Txias cov kua hauv lub twj tso kua mis thiab tom qab ntawd pib.
(6) Yog tias muaj lub zog ua kom muaj zog thiab suab nrov thaum lub sijhawm Diesel cav tus kheej- Presh} Pre}} Preading twj tso kua mis, nws yuav tshwm sim los ntawm cavitation ntawm lub twj tso kua mis. Cov teeb meem ntawm cavitation yog ob: ib yog tus nqi ntws ntau ntawm cov inlet yeeb, thiab lwm yam yog lub nqus dej deb. Thaum tus nqi txaus siab dhau lawm, qhov Overlet Regulating valve tuaj yeem hloov kho kom tau kev ntsuas siab nyeem, thiab cov blockage nyob rau hauv lub inlet raj xa dej tuaj yeem tshem tawm sai sai; Thaum lub hau kev deb yog dhau lawm, kev teeb tsa qhov siab ntawm lub twj tso kua mis tuaj yeem raug txo kom zoo.
(7) Thaum cov twj tso kua mis nres rau qee qhov laj thawj thaum lub sijhawm tsis muaj kev tawm tsam, tab sis kuj ua kom pom tseeb tias cov lus qhia thiab lub luag haujlwm rau kev pib.
(8) Ua tib zoo saib xyuas seb puas muaj to tsis muaj kev to taub hauv lub raj hluav taws xob ntawm lub roj diesel {}} pre} Presh priming twj tso kua mis.
