Canjin Matsi Don Tsarin Refrigeration
Ana amfani da maɓallin matsa lamba mafi yawa a cikin tsarin firiji, a cikin tsarin bututun bututun matsa lamba da ƙananan matsa lamba, don kare mummunan matsa lamba na tsarin don hana lalacewa ga compressor.
Bayan an cika, na'urar tana kwarara cikin harsashi na aluminium (wato, a cikin maɗaurin) ta cikin ƙaramin rami da ke ƙarƙashin harsashin aluminum. Kogon ciki yana amfani da zobe na rectangular da diaphragm don raba na'urar sanyaya daga bangaren lantarki kuma a rufe shi a lokaci guda.
Lokacin da matsa lamba ya kai ƙananan matsi mai ƙima 0.225 + 0.025-0.03MPa, ƙananan diaphragm (1 yanki) yana jujjuya shi, wurin zama na diaphragm yana motsawa sama, kuma wurin zama na diaphragm yana tura babban reed don matsawa sama, kuma lambobin sadarwa a kan babban reshe suna kan farantin rawaya na kasa. Ana tuntuɓar lamba na compressor, wato, an haɗa ƙananan matsa lamba, kuma compressor ya fara gudu.
Matsin ya ci gaba da tashi. Lokacin da ya kai darajar cire haɗin 3.14 ± 0.2 MPa, diaphragm mai girma (3 guda) yana jujjuyawa, yana tura sandar fitarwa zuwa sama, kuma sandar ejector yana dogara a kan ƙananan reshe, don haka ƙananan reed yana motsawa zuwa sama. da lamba a kan ƙananan farantin rawaya An raba wurin da lambar sadarwa a kan babban redu, wato, babban matsa lamba yana katse, kuma compressor ya daina aiki.
Matsin lamba a hankali yana daidaitawa (watau raguwa). Lokacin da matsa lamba ya sauko zuwa ƙimar maɗaukakin matsi mai ƙarfi ya rage 0.6 ± 0.2 MPa, diaphragm mai girma ya dawo, sandar ejector yana motsawa ƙasa, kuma ƙananan reed ya dawo. Lambobin da ke kan ƙananan farantin rawaya da lambobin sadarwa a kan sandar sama an dawo dasu. Alamar lamba, wato, an haɗa babban matsa lamba, compressor yana aiki.
Lokacin da matsa lamba ya sauko zuwa ƙimar yanke-ƙananan matsa lamba na 0.196 ± 0.02 MPa, diaphragm mai ƙarancin ƙarfi ya dawo, wurin zama na diaphragm yana motsawa ƙasa, reed na sama ya sake saita ƙasa, kuma lambar sadarwa akan babban ganyen rawaya ya rabu da lambar sadarwa. a kan ƙananan reed, wato, ƙananan matsa lamba cire haɗin , Compressor ya daina aiki.
A ainihin amfani, ana katse maɓalli lokacin da babu matsi. An shigar da shi a cikin tsarin na'urar kwandishan mota. Bayan an cika refrigerant (yawanci 0.6-0.8MPa), matsa lamba yana cikin yanayin kunnawa. Idan refrigerant bai zubo ba, Tsarin yana aiki kullum (1.2-1.8 MPa);Tyana kunnawa kullum.
when zafin jiki yana sama da digiri bakwai ko takwas, Lokacin da tsarin ba ya aiki akai-akai, irin su rashin zafi mai zafi na na'ura ko datti / ƙanƙara na tsarin, kuma tsarin tsarin ya wuce 3.14 ± 0.2 MPa, za a juya canji. kashe; Idan refrigerant yayyo ko zafin jiki yana ƙasa da digiri bakwai ko takwas, kuma tsarin tsarin yana ƙasa da 0.196 ± 0.02 MPa, za a kashe maɓallin. A takaice, mai kunnawa yana kare kwampreso.
