Ukushaywa kwe-compressor ngamanzi kwenzeka ngoba i-refrigerant ewuketshezi ingena kwisilinda. Lapho inani loketshezi lingena enanini elincane lesilinda ngaphandle kwesiqandisi, inani elingaphezulu hhayi nje kuphela lesiqandisi, kodwa futhi lizolimaza isilinda, umonakalo omkhulu emshinini.
Ukulungiswa kokusebenza kwe-compressor yesigaba esisodwa esimanzi
I-compressor wet stroke kufanele ivale ngokushesha i-compressor suction valve, ngenkathi ivala i-throttle valve ukuze imise uketshezi. Uma izinga lokushisa lokumunca lisaqhubeka nokwehla, kufanele ucime i-suction valve, bese uqala idivayisi yokukhulula, kuze kube yilapho izinga lokushisa likhuphuka, uvule i-suction valve kancane, bese ukhuphula umthwalo kancane kancane, kuze kube yilapho umshini ubuyela ekusebenzeni okuvamile. Uma ubhekene ne-wet stroke, kufanele unake ukulungisa ingcindezi kawoyela, uma ingcindezi kawoyela iphansi kakhulu kufanele ivalwe. Uma kwenzeka i-wet stroke enkulu, umshini kufanele umiswe kuqala bese uqhutshwa futhi lapho i-liquid refrigerant icutshungulwa, okwamanje, amanzi afakwe ku-cooler kanye ne-water jacket kufanele akhuliswe ukuze kuvinjelwe ukubanda nokuqhekeka. Ukuze kuqalwe kabusha ukusebenza komshini ngokushesha okukhulu, i-liquid refrigerant emzimbeni ingakhishwa nge-venting valve.
Ukulungiswa kokusebenza kwe-compressor enezigaba ezimbili ye-wet stroke
I-compressor enengcindezi ephansi ivame ukubangelwa ukushisa okubangelwa ukuhwamuka noma imishini enengcindezi ephansi ebangelwa ukusebenza okungafanele, indlela yokwelapha nge-compressor yesigaba esisodwa.
Ukucindezeleka okuphezulu kwe-compressor kuvame ukubangelwa ukuthi izinga loketshezi olupholile eliphakathi nendawo liphezulu kakhulu. Ukwelashwa, kufanele kuqala kuvaliwe isigaba sokucindezela okuphansi kwe-valve yokumunca, kulayishwe umthwalo omncane, bese kuvalwa i-valve yokumunca okuphakathi nendawo, kuvaliwe isigaba sokucindezela okuphezulu kwe-valve yokumunca bese kulayishwa ngesikhathi esifanele. Lapho isigaba sokucindezela okuphezulu sibuyela ekusebenzeni okuvamile, bese kuvulwa isigaba esikhulu sokucindezela okuphansi kwe-valve yokumunca, kubuyiselwe ekusebenzeni okuvamile, kanye nokunikezwa koketshezi olupholile oluphakathi nendawo. Uma iqhwa lesigaba sokucindezela okuphezulu libi kakhulu, i-compressor kufanele imiswe ngokushesha.
Uma isigaba sokucindezela okuphezulu siqandisiwe kakhulu, i-compressor kufanele imiswe ngokushesha bese i-intercooler ikhishwa amanzi, kanti eminye imisebenzi kufanele ifane neyemishini yesigaba esisodwa.3 Izinyathelo zokuvimbela kufanele zithathwe ukuze kubhekwe izinga lokushisa lokumunca, kulungiswe kahle izinga loketshezi lezitsha, futhi kulawulwe ngokucophelela i-valve yokumunca. Kutholakale ukuthi umshini ubonakala izimpawu zokushaywa ezimanzi ezifana nalezi: amazinga okushisa okumunca nokukhipha awe ngokushesha, igumbi lokumunca lomshini, umzimba womoya obandayo, umsindo ogijima kakhulu, umsindo we-valve awucacile, njll. kufanele kubhekwene nawo ngesikhathi esifanele.
