Kugawana chidziwitso choyambirira cha coil valavu ya solenoid

1. mfundo ya ntchito

Tikudziwa kuti ma valve a solenoid amatha kugawidwa m'mitundu yambiri malinga ndi momwe amachitira komanso momwe amapangidwira. Ena amagwira ntchito zamadzimadzi ndipo ena amagwiritsa ntchito mpweya, koma ma valve ambiri a solenoid amapangidwa ndi ma valve, kotero kuti awiriwo akhoza kupatukana. Nthawi zambiri, valavu yake imapangidwa ndi zida za ferromagnetic. Pamene koyiloyo ipatsidwa mphamvu, mphamvu ya maginito imakopa pakati pa valve, ndipo valavu imakankhira valavu kuti amalize kutsegula ndi kutseka.

2. Chifukwa cha kutentha thupi

Pamene coil ya solenoid valve ikugwira ntchito, chitsulo chachitsulo chidzakopeka, zomwe zidzapangitsa kuti apange maginito otsekedwa. Inductance ikakhala yayikulu, mwachilengedwe imatsogolera kutentha. Kutentha kwakukulu, chitsulo chachitsulo sichingakopeke bwino chikapatsidwa mphamvu, kotero kuti inductance ndi impedance ya coil idzachepetsedwa ndipo panopa idzawonjezeka, zomwe zidzachititsa kuti coil panopa ikhale yaikulu kwambiri. Pakalipano, kuwonongeka kwa mafuta, zonyansa ndi mapindikidwe zidzakhudza ntchito yachitsulo pakati. Ikangopatsidwa mphamvu, imagwira ntchito pang'onopang'ono ndipo sichingakopeke.

3.Kodi mphamvu ya maginito ikukhudzana bwanji ndi kukula?

Nthawi zambiri, kukula kwa mphamvu ya maginito ya koyilo ya valavu ya solenoid kumagwirizana kwambiri ndi kuchuluka kwa matembenuzidwe, ma waya awiri ndi gawo la maginito achitsulo. Zamakono zitha kugawidwa mu DC ndi kulumikizana, pomwe coil ya DC solenoid valve imatha kuchotsedwa pachimake chachitsulo, koma batire yolumikizirana siyingachite izi. Batire yolumikizirana ikapeza kuti koyilo imachita izi, zomwe zili mu koyiloyo zimawonjezeka, chifukwa zimakhala ndi mphete yayifupi mkati.

4.Kusankhana bwino kapena koyipa

Ngati tikufuna kuweruza ngati solenoid valve coil ndi yabwino kapena yoipa, tingagwiritse ntchito multimeter kuti tiyese kukana kwa valve solenoid. Kwa koyilo yabwino, kukana kuyenera kukhala kozungulira 1K ohms. Ngati iyesedwa, imapezeka kuti kukana kulibe malire kapena pafupi ndi zero, kusonyeza kuti ndi yochepa-yozungulira tsopano ndipo sangathe kugwiritsidwa ntchito.
