Common Faults Ntawm Ntsia Hlau Compressors

1. Qhov txawv txav Compression Ratio: Compression ratio yog ib lub tswv yim paub rau cov neeg paub txog kev ua haujlwm compressor. Qhov txawv ntawm cov ntsia hlau compressors thiab piston compressors yog tias piston compressors tsuas yog nyob rau hauv - compressors, thaum ntsia hlau compressors tau dhau - compression.

** Screw Compressor Ratio Siab dhau:** Lub kaw lus yuav txawv ntawm nws tus nqi tsim. Cov tsos mob tseem ceeb muaj xws li qhov kub thiab txias siab heev, thiab qhov nqus nqus siab thiab kub siab heev.

** Screw Compressor Ratio Tsawg dhau:** Qhov no feem ntau cuam tshuam rau cov hlab ntsha ntub dej. Qhov tseeb, ntsia hlau compressors muaj kev cuam tshuam ntau dua rau cov hlab ntsha ntub. Yog hais tias ib tug loj npaum li cas ntawm cov kua rov qab mus rau lub compressor, nws yuav dilute cov roj lubricating, uas ua rau cov nyhuv tib yam li qhov kub thiab txias heev.

2. Tsawg Condenser Efficiency: Tsawg condenser efficiency feem ntau cuam tshuam rau cov kua dej kub thiab seb cov kua tuaj yeem tsim. Ntau dhau condensation kuj muaj teeb meem. Piv txwv li, yog tias qhov ntsuas kub ntawm qhov nruab nrab qis thiab cov txiaj ntsig condensation zoo dhau lawm, cov kua yuav nkag mus rau hauv lub evaporator zoo dua, uas ua rau lub tshuab nqus tsev qis heev thiab qis expansion valve rhiab heev, uas tuaj yeem ua rau cov kua slugging thaum pib.

3. Tsawg los yog High evaporator Efficiency: Tsawg evaporator efficiency feem ntau cuam tshuam rau qhov txias ntawm cov khoom raug txias, thaum nws cov nyhuv ntawm compressor muaj feem xyuam rau cov hlab ntsha ntub. Kev ua haujlwm siab tuaj yeem ua rau kev nqus dej ntau dhau, uas ua rau muaj kev cuam tshuam rau lub compressor qhov kub thiab txias. Cov mob stroke ntub dej tuaj yeem txiav txim siab siv lub siab -enthalpy daim duab lossis los ntawm kev rho tawm qhov kub thiab txias ntawm qhov tso tawm.

4. Cov teeb meem roj hluav taws xob: Cov no feem ntau cuam tshuam txog roj zoo, huv si, thiab rov qab roj kub. Lub luag haujlwm tseem ceeb ntawm cov roj lubricating hauv cov ntsia hlau compressor tub yees yog lubrication, txias, thiab sealing. Cov roj rov qab kub tau cuam tshuam rau cov ntsia hlau compressor lub neej; Qhov kev pom zoo ua haujlwm kub feem ntau yog 40-60 degree, txawm hais tias qee lub tuam txhab hais qhia 70℃lossis 80 degree. Cov roj kub ntau dhau tuaj yeem ua rau roj coking, cuam tshuam cov roj zaj duab xis tsim. Roj kub kuj tseem cuam tshuam rau qhov kub thiab txias, yog li cuam tshuam qhov sib piv compression.

5. Roj boiling thaum pib lossis ua haujlwm: Qhov kev ua txhaum no qhia tias cov kua nkag mus rau hauv lub compressor, los yog cov tub yees ntau dhau hauv cov roj lubricating. Thov kho lub throttling mechanism thiab xyuas rau overcharging ntawm refrigerant.

6. Cov roj tsis txaus lossis ntau dhau: Cov roj tsis txaus: Xav txog seb cov roj cais tawm puas yog, cov roj ntxiv tsis txaus, lossis muaj teeb meem ntawm cov roj rov qab los ntawm cov evaporator. Thaum lub sij hawm tu, xyuas seb puas muaj cov kua theem hauv lub receiver; xav txog ib tug faulty throttling mechanism los yog tsis tsim nyog installation. Cov roj ntau dhau: Xav txog cov roj lim lim, lossis cov tub yees sib xyaw rau hauv cov roj.

7. Kev Kub Ntxhov Siab Tshaj: Kev kub tawm siab ntau ntau yam ua rau, feem ntau yog xav txog cov tub yees ntau dhau, siab nqus dej ntau dhau, tsis muaj cua sov dissipation, tsis ruaj khov, thiab lwm yam.

8. Tsawg los yog Fluctuating Suction Pressure: Tsawg suction siab: Qhov tseem ceeb muaj xws li cov tub yees tsis muaj peev xwm, throttling mechanism malfunction, siab condensing kub heev, kua slugging, thiab lwm yam.
