Ngokulawula ukubambezeleka, ukulawula okuphambene, ukushintsha kweyunithi yokucindezela, ukusula amaphutha, ukuvikelwa kwephasiwedi neminye imisebenzi.
Inezici zokumelana nokushaqeka okuhle, impilo ende, ukumelana nomfutho wokushaya, njll. Ifaneleka kakhulu ekucindezelweni kwe-hydraulic, kuma-compressor omoya anomfutho ophezulu, abahlanzi abanomfutho ophezulu kanye nemishini ehlukahlukene yokulawula okuzenzakalelayo.
Kunezinhlobo ezintathu eziyisisekelo zama-air compressor: uhlobo lokujika, uhlobo olujikelezayo kanye nohlobo lwe-centrifugal. Ngokuvamile ingahlukaniswa ngale ndlela. Ingcindezi kuma-air compressor ajwayelekile ezimboni incane njenge-2hp kuya ku-10,000hp. Ama-air compressor asetshenziswa kakhulu ekulawuleni umoya, ekusebenzeni, emishinini yokujova, kumathuluzi omoya, ekusebenzeni kokukhipha umoya kanye nakwezinye izinhlelo zokusebenza. I-air compressor evame kakhulu ngokuvamile inomfutho osebenzayo ongu-125pis (cishe ama-atmospheres angu-8.6) kanye nesilinganiso sokugeleza kwegesi esingu-1CFM kuya ku-15000CFM.
Ngokuvamile, isimiso sokulawula se-air compressor ukusebenzisa ingcindezi yomoya ocindezelwe (isilinda) ukuze isebenze ku-pressure switch. Uma ingcindezi inkulu kune-pressure value ye-pressure switch, i-switch izonqamula amandla okulawula e-contactor bese iyeka. Uma ingcindezi iphansi kune-pressure value ye-pressure switch Cishe u-60%, i-switch ivula ukunikezwa kwamandla okulawula e-contactor bese isebenza. Ukuze kuqinisekiswe ukuthi ingcindezi igcinwa ngaphakathi kwebanga elihleliwe, futhi kufezwe umphumela wokusetshenziswa kwe-air outlet yangemuva. Ngokuvamile, kusetshenziswa ama-pressure switch omshini, anokunemba okuphansi kokulawula kanye nemikhawulo emincane elungisekayo ephezulu nephansi, engafaneleki ukulawula okunembile.
I-Shanghai MeokonIsilawuli sengcindezi yesibonisi sedijithali sochungechunge lwe-MD-Sisebenzisa isekethe ehlanganisiwe yakamuva eqondene nohlelo lokusebenza kanye nomklamo wenzwa yokucindezela onembile kakhulu. Lo mkhiqizo ulula kakhulu ekusethweni kokucindezela, ububanzi obulungisekayo obubanzi, ukunemba okuphezulu, kanye nokunemba okuphezulu kanye nokuzinza.
Isilawuli sokucindezela kokubonisa kwedijithali sochungechunge lwe-MD-S siyiswishi esihlakaniphile esisebenza ngezindlela eziningi esihlanganisa ukulinganisa ingcindezi, ukubonisa nokulawula. Lapho ingcindezi ifinyelela inani elinqunyiwe, isignali yokulawula iyaphuma, bese imishini elawulwayo ivuliwe noma ivaliwe ukuze kufezwe injongo yokulawula okuzenzakalelayo. Lolu chungechunge lwabalawuli lunezinzuzo zokunemba okuphezulu, i-hysteresis ephansi, impendulo esheshayo, ukusebenza okuzinzile nokuthembekile, ukusebenza okulula kanye nokufakwa okulula nokuguquguqukayo. Ungumkhiqizo wobuchwepheshe obuphezulu wokulawula ingcindezi okuzenzakalelayo kusetshenziswa ubuchwepheshe be-microcomputer. Unezici zokunemba okuphezulu, i-hysteresis ephansi, impendulo esheshayo, ukusebenza okuzinzile nokuthembekile, ukusebenza okulula nokufakwa okulula.
