Wet Compression Test . Lub tog raj kheej compression xeem yog ua los txheeb xyuas cov thooj voos kheej kheej uas tsis zoo compression . Yog tias lub tog raj kheej muaj qis compression , ua a ntub compression test los qhia seb nws puas yog lub valve tsis zoo, lub taub hau gasket, lossis hnav piston rings ua rau muaj teeb meem.

Ib yam li ntawd, qhov txawv ntawm qhov kev ntsuam xyuas ntub thiab qhuav compression yog dab tsi?

A ntub compression test yog zoo ib yam li a kev sib tw qhuav qhuav tshwj tsis yog nws tau ntxiv cov roj tso nyob rau hauv txhua lub tog raj kheej. Ib lossis ntau lub tog raj kheej muaj kev nyeem ntawv tsawg dua 100 psi ntawm lub kev sib tw qhuav qhuav . • Ib lub tog raj kheej los yog ntau tshaj 20% txawv los ntawm lwm lub tog raj kheej ntawm a qhuav compression xeem.

Kuj Paub, yuav qhov kev ntsuas compression qhia lub taub hau tsis zoo? Koj ua tau kuj sim ua a compression xeem ntawm koj lub cav los nrhiav a taub hau gasket xau. Yog koj taub hau gasket ua blu, it yuav tso cai rau cov cua compressed hauv 1 lossis ntau lub tog raj kheej kom los ntshav tawm mus rau hauv qhov txias txias kom txo qis compression hauv lub tog raj kheej ntawd.

Thiaj li, dab tsi yog qhov ntsuas kev ntsuas zoo nyeem?

Raws li txoj cai dav dav a compression ntawm 135 PSI lossis zoo dua yog qhov zoo heev. Ib yam li ntawd, A compression ntawm 85 PSI lossis qis dua yog qhov phem heev. Qhov xwm txheej xav tau tshaj plaws yog txhua lub tog raj kheej muab tib yam lossis ze rau ib yam nyeem ntawv . Ntxiv mus, Tias nyeem ntawv yuav tsum siab dua 135 PSI.

Koj yuav kuaj xyuas lub nplhaib piston tsis zoo li cas?

Kos npe rau koj piston rings yuav tsum tau hloov

  1. Cov pa luam yeeb ntau dhau. Yog tias cov pa luam yeeb tawm ntawm koj lub cav yog xim grey thiab tshwj xeeb yog tuab, ces nws tuaj yeem txhais tau tias koj lub nplhaib piston yuav tsum tau hloov.
  2. Siv roj ntau dua li ib txwm. Yog tias koj cov roj noj zoo li tau nce tag nrho, tom qab ntawd cov piston qub qub tuaj yeem yog tus neeg ua txhaum.
  3. Tsis muaj zog.
  4. Txo kev ua haujlwm.
