Kodi Zisindikizo za Makina a Pampu Zimatenga Nthawi Yaitali Bwanji?
Nthawi yogwira ntchito ya zisindikizo zamakina a pampu ndi gawo lofunika kwambiri pakukonza ndi kugwiritsa ntchito bwino ntchito m'mafakitale osiyanasiyana. Nthawi zambiri, pansi pa mikhalidwe yabwino, chisindikizo chamakina chosamalidwa bwino chingakhalepo kwa chaka chimodzi mpaka zitatu chisanayambe kufunikira kusinthidwa kapena kukonzedwa. Komabe, ndikofunikira kudziwa kuti nthawi yeniyeni yogwirira ntchito imatha kusiyana kwambiri kutengera zinthu zingapo.

Zinthu zazikulu zomwe zimakhudza kulimba kwa zisindikizo zamakina a pampu ndi monga momwe zimagwiritsidwira ntchito m'mafakitale, momwe zimagwirira ntchito monga kutentha ndi kupanikizika, mtundu wa madzi omwe akupopedwa, komanso kupezeka kwa zinthu zowononga kapena zowononga mkati mwa madziwo. Kuphatikiza apo, kapangidwe ka chisindikizocho ndi kapangidwe kake (koyenerana ndi kosalinganika, katiriji motsutsana ndi bellow, ndi zina zotero) zimagwira ntchito yofunika kwambiri pakutsimikiza kutalika kwake.

Kusamalira nthawi zonse ndi kukhazikitsa bwino ndikofunikira kwambiri kuti zisindikizo izi zizikhala ndi moyo wautali. Kuonetsetsa kuti nkhope za zisindikizozo zikhale zoyera komanso zosawonongeka, kuyang'anira zizindikiro zakuwonongeka, komanso kutsatira zomwe wopanga akufuna kuti zigwiritsidwe ntchito kungathandize kuti zigwire ntchito bwino kwambiri.

Kodi Chisindikizo cha Makina Chingawonjezeke Bwanji?
Kutalikitsa nthawi yogwira ntchito ya makina osindikizira m'mapampu amadzi kumafuna kukonza mosamala, kuyika bwino, ndikugwiritsa ntchito mkati mwa magawo omwe atchulidwa.

Kusankha bwino kutengera zomwe pulogalamuyo ikufuna kumatsimikizira kuti ikugwirizana ndi momwe ntchito ikuyendera. Kuyang'anira ndi kukonza nthawi zonse kumachepetsa kuwonongeka ndi kupewa kulephera kusanayambe kukhala kofunikira. Kuonetsetsa kuti madzi oyera ndi oyeretsedwa n'kofunika kwambiri chifukwa zinthu zodetsa zimatha kufulumizitsa kuwonongeka. Kukhazikitsa zowongolera zachilengedwe, monga mapulani otsekera, kusamalira kutentha bwino ndikuchotsa tinthu tomwe tingawononge nkhope za chisindikizo.

Kulinganiza magawo ogwirira ntchito kuti mupewe kupsinjika kwambiri kapena kutentha komwe kumapitirira zomwe chisindikizocho chikufuna n'kofunika kwambiri kuti mukhale ndi moyo wautali. Kugwiritsa ntchito mafuta odzola ndi makina ozizira ngati pakufunika kumathandiza kuti chisindikizo chigwire ntchito bwino. Kupewa kuuma kwa chisindikizo kumasunga umphumphu wa chisindikizo pakapita nthawi.

Kuphunzitsa ogwira ntchito njira zabwino zoyambira ndi kuzimitsa makina kumathandiza kupewa kupsinjika kosafunikira pa zisindikizo zamakina. Kutsatira ndondomeko yokonza nthawi ndi nthawi kuti muwone zinthu monga ma spring, bellows, ndi lock collars kuti muwone ngati pali zizindikiro za kuwonongeka kapena kuwonongeka kumachita gawo lofunika kwambiri pakuwonjezera nthawi ya ntchito.

Mwa kuyang'ana kwambiri pa kusankha koyenera, kulondola kwa kukhazikitsa, njira zodzitetezera ku kulowa kwa zinthu zodetsa, komanso kutsatira malangizo ogwirira ntchito, moyo wa zisindikizo zamakina a pampu yamadzi ukhoza kukulitsidwa kwambiri. Njira imeneyi sikuti imangoteteza kudalirika kwa makina a pampu komanso imawongolera magwiridwe antchito onse mwa kuchepetsa nthawi yogwira ntchito komanso ndalama zokonzera.

Pomaliza
Mwachidule, chisindikizo cha makina a pampu yamadzi ndi chinthu chofunikira kwambiri chomwe chimapangidwa kuti chiteteze kutuluka kwa madzi ndikuwonetsetsa kuti mapampu a centrifugal akuyenda bwino mwa kusunga chotchinga pakati pa madzi omwe akupopedwa ndi malo akunja.
