Hanyar magance matsalar al’amarin da ruwan kwampreta ya bugi silinda a cikin masana’antu chiller tsarin

1. Abubuwan da ke haifar da ciwon bugun jini

① Lokacin amfani da kulawar hannu, bawul ɗin magudanar an daidaita shi ba daidai ba, buɗewar ya yi girma sosai, ko bawul ɗin iyo ba a rufe tam;

②Bawul ɗin faɗaɗawar thermal ya kasa, ko kuma an shigar da kwan fitila mai gano zafin jiki ba daidai ba, kuma tuntuɓar ba ta gaske ba ce, yana haifar da buɗewa da yawa;

③Maɗaɗɗen ƙanƙara mai ƙanƙara yana da kauri kuma kayan ya yi ƙanƙanta;

④ Yawan tara mai a cikin tsarin;

⑤Irin sanyaya na kwampreso ya yi girma da yawa, ko nauyin zafi na ɗakunan ajiya yana da ƙananan;

⑥ Daidaita daidaitaccen aikin bawul;

⑦Cikin refrigerant a cikin tsarin firiji yana cike da na’ura mai yawa;

⑧The ruwa wadata solenoid bawul ba a rufe tam;

⑨ A cikin sake zagayowar matsawa na matakai biyu, lokacin da bawul ɗin tsotsa na matakin ƙananan matsa lamba ba zato ba tsammani ya rufe ko buɗe (ko adadin na’urorin aiki ba zato ba tsammani ya ragu kuma yana ƙaruwa), kuma a cikin intercooler. Ƙwaƙwalwar maciji ta shiga cikin ruwa ba zato ba tsammani, wanda zai iya haifar da rigar bugun jini na matsa lamba mai girma.

A takaice dai, akwai abubuwa da yawa da ke haifar da jikawar bugun jini na kwampreso, kuma ya kamata a gano dalilan kuma a kawar da su daidai da takamaiman yanayi.

2. Kayan aiki, kayan aiki da kayan aiki da aka yi amfani da su don gano gazawar rigar bugun jini na compressor refrigeration

①Instrument: matsa lamba ma’auni, multimeter, matsa mita, ma’aunin zafi da sanyio, biyu qi mita.

②Kayan aiki: wrenches, kayan aikin faɗaɗa bututu, cika bawuloli, filaye mai nuni, filawa, fitilu, kayan aiki na musamman.

③Kayan aiki: kwalban ruwa mai aiki, kwalban nitrogen, famfon injin, cikakken saitin walda na gas.

3. Hanyar aiki gabaɗaya don gano raunin bugun jini na kwampreshin firiji

Tunda tsarin na’urar sanyaya na’urorin chillers na masana’antu wani tsari ne mai rikitarwa wanda ya hada da na’urori masu auna sigina, evaporators, bawul na fadadawa, da na’urorin kayan aiki da yawa waɗanda ke da alaƙa da tasiri da juna, da zarar na’urar ta gaza, ba kawai a mai da hankali kan wasu A matakin gida ba. wajibi ne a gudanar da bincike mai zurfi da cikakken bincike game da dukkanin tsarin. A taƙaice, hanyar gano gabaɗaya ita ce:

“Saurara ɗaya, taɓawa biyu, kallo uku, bincike huɗu” saitin hanyoyin asali.

Kallo ɗaya: kalli matsin tsotsa da matsa lamba na kwampreso; dubi yanayin sanyaya na ɗakin sanyaya; dubi yanayin sanyi na mai fitar da ruwa; dubi yanayin sanyi na bawul ɗin fadada thermal.

Saurari na biyu: sauraron sautin kwampreso yana gudana, yakamata a sami motsin bawul kawai. Lokacin da akwai sautin “ta-ta”, shine tasirin sautin guduma na ruwa; sauraron sautin firiji da ke gudana a cikin bawul ɗin fadadawa; sauraron sautin mai sanyaya; sauraron sautin bawul ɗin solenoid; saurare ko akwai rawar jiki a fili a cikin bututun.

Taɓawa uku: taɓa yanayin zafin gaba da na baya na compressor; taɓa yanayin zafi na kwampreso Silinda liner da Silinda kai; taba yanayin zafi na tsotsa da bututun shaye-shaye. Bincike guda hudu: Yi amfani da ka’idodin da suka dace na na’urar sanyaya don tantancewa da yin hukunci game da lamarin, gano dalilin gazawar, da kuma kawar da shi ta hanyar da aka yi niyya. Hukuncin gazawar guduma na ruwa ba wai kawai ya dogara ne akan sanyin bututun tsotsa ba, amma galibi daga digo mai kaifi a cikin yawan zafin jiki. A wannan lokacin, matsi na shaye-shaye ba zai canza da yawa ba, amma silinda, crankcase, da ɗakin shaye-shaye duk sun shafi. Sanyi ko sanyi. A cikin yanayin girgiza na’ura mai aiki da karfin ruwa, yana iya lalata tsarin lubrication, yana dagula aikin famfo mai, da raguwar bangon Silinda sosai, kuma ya huda kan Silinda a lokuta masu tsanani.

4. Hanyar warware matsalar da kuma maido da aiki na yau da kullun na injin kwampreso rigar bugun bugun jini

Magance hadurran girgizar ruwa ya kamata a yi cikin gaggawa, kuma a lokuta masu tsanani, ya kamata a gudanar da aikin motar gaggawa. Lokacin da ɗan ƙaramin jika ya faru a cikin kwampreso mai mataki-ɗaya, kawai bututun tsotsawa ya kamata a rufe, a rufe bawul ɗin samar da ruwa na tsarin ƙawance, ko kuma a rage ruwan da ke cikin akwati. noodle. Kuma kula da matsa lamba mai da yawan zafin jiki. Lokacin da zafin jiki ya tashi zuwa 50 ℃, gwada buɗe bawul ɗin tsotsa. Idan yawan zafin jiki ya ci gaba da tashi, za ku iya ci gaba da buɗe shi, kuma idan yanayin zafi ya ragu, sake rufe shi.

Don “rigar bugun jini” na kwampreso-mataki-mataki biyu, hanyar jiyya na ƙananan matakan rigar bugun jini daidai yake da na kwampreso-mataki ɗaya. Amma lokacin da akwai adadin ammonia mai yawa da ke gaggawar shiga cikin silinda, ana iya amfani da compressor mai matsa lamba don rage damuwa da fitar da su ta hanyar intercooler. Kafin a sauke, ruwan da ke cikin intercooler ya kamata a zubar da shi a cikin bokitin magudanar ruwa, sannan ya kamata a rage matsa lamba. Ya kamata a sanyaya jaket ɗin ruwa mai sanyaya silinda da mai kafin rage matsa lamba: zubar da ruwan sanyi a cikin na’urar ko buɗe babban bawul ɗin ruwa.

Lokacin da matakin ruwa na intercooler ya yi yawa, babban matsa lamba yana nuna “rigar bugun jini”. Hanyar magani yakamata ta fara kashe bawul ɗin tsotsa na ƙananan matsa lamba, sannan a kashe bawul ɗin tsotsa na babban matsa lamba da bawul ɗin samar da ruwa na intercooler. Idan ya cancanta, fitar da ruwan ammoniya a cikin na’urar sanyaya a cikin ganga mai fitarwa. Idan babban matsa lamba yana da sanyi sosai, dakatar da compressor mai ƙarancin ƙarfi. Hanyar jiyya ta gaba ɗaya ce da ta mataki ɗaya.
