Kodi ntchito ya valavu yowongolera kuthamanga kwa crankcase ndi yotani?
1, valavu yolamulira kuthamanga kwa crankcase ya gawo losungunula mpweya, kusungunula mpweya pambuyo posankha ndi mphamvu yoziziritsira yoyesedwa nthawi zambiri imatsekedwa panthawi ndi pambuyo pa gawolo kuti ichepetse kuthamanga kwa crankcase mu nthawi yayitali yomwe idakhazikitsidwa kale kuti ipewe kudzaza kwa injini ya compressor;
2. Mtundu uwu wa valavu Kuchuluka kwa valavu yamtunduwu kumagwirizana ndi zinthu zitatu izi: kapangidwe ka mphamvu yokoka pambuyo pozimitsa. Kupanikizika kudzasintha zokha firiji yomwe imatuluka mu evaporator mpaka compressor itatha kupirira mphamvu yokoka yovomerezeka yomwe compressor kapena wopanga chipangizocho amalangiza (ndiko kuti, mtengo wokhazikika wa valavu);
3, ndi kutsika kwa mphamvu ya valavu. Kusiyana pakati pa mphamvu ya kapangidwe kake ndi mtengo wa valavu kumatsimikiza kuchuluka kwa valavu yoti igwiritsidwe ntchito. Chifukwa chake, mtengo wa valavu uyenera kukhala wokwera momwe mungathere, koma musapitirire mtengo womwe wopanga compressor kapena unit amalangiza.
