Bawul Relief PC220-6 Excavator aminci bawul 708-2L-04740

Akwai nau'ikan bawul ɗin solenoid da yawa akan ƙananan haƙa. Da farko, dole ne mu san ka'idar aiki na solenoid bawul. Solenoid bawul na injin hakowa yana amfani da na'urar lantarki don tura bawul core don sarrafa alkiblar matsewar iska, ta yadda za a sarrafa alkiblar mai kunna huhu. Bawul ɗin shugabanci na lantarki bisa ga buƙatu daban-daban na iya cimma hanyoyi biyu uku, biyu biyar da sauransu
Na farko, tsarin na solenoid bawul: nada, magnet, ejector sanda.

Ka'idar aiki na bawul ɗin solenoid na ƙaramin excavator shine cewa lokacin da aka haɗa na'urar tare da na yanzu, yana haifar da magnetism, yana jan hankalin juna tare da maganadisu, magnet yana jan sandar fitarwa, kashe wutar lantarki, maganadisu da sandar fitarwa. an sake saitawa, kuma an kammala aikin aiki.

Na biyu, electromagnet da ake amfani da shi don aiki da bawul ɗin solenoid akan ƙaramin excavator ya kasu zuwa AC da DC.

Wutar lantarki na AC electromagnet gabaɗaya 220V, wanda ke da alaƙa da babban ƙarfin farawa, gajeriyar juyawa da ƙarancin farashi. Duk da haka, lokacin da bawul din ba ya makale sosai kuma ba a tsotse baƙin ƙarfe ba, electromagnet yana da sauƙi don ƙonewa saboda matsanancin halin yanzu, don haka yiwuwar aiki ba shi da kyau, aikin yana da tasiri, kuma rayuwa ta takaice. Wutar lantarki na DC electromagnet gabaɗaya 24V ne, kuma fa'idarsa shine yana aiki da dogaro, ba zai ƙone ba saboda mannewar spore, kuma yana da tsawon rai.

Na uku, da rarrabuwa na solenoid bawuloli

1, bawul ɗin solenoid kai tsaye
Lokacin da wutar ke kunne, ƙarfin lantarki da ke haifar da na'urar lantarki ta ɗaga gunkin rufewa daga wurin zama, kuma ana kiran bawul ɗin. Lokacin da aka kashe wutar lantarki, bawul ɗin solenoid ya ɓace, bazara yana danna ɓangaren rufewa akan wurin zama, kuma bawul ɗin yana rufe. Yana da alaƙa da aiki na yau da kullun a cikin injin, matsa lamba mara kyau da matsa lamba sifili, amma diamita gabaɗaya bai wuce 25mm ba.

2, matukin jirgi solenoid bawul
(Pilot solenoid bawul aiki ka'idar)

Lokacin da aka kunna wutar lantarki, ƙarfin lantarki yana buɗe rami na matukin jirgi, matsa lamba na sama yana faɗuwa da sauri, yana haifar da ƙarancin matsa lamba da babban bambanci a kusa da ɓangaren rufewa, matsa lamba na ruwa yana tura ɓangaren rufewa don matsawa sama, bawul ɗin yana buɗewa. Lokacin da aka kashe wutar lantarki, ƙarfin bazara yana rufe ramin matukin, kuma matsa lamba mai shiga yana haifar da ƙananan ƙarancin matsa lamba a kusa da sashin rufe bawul ta ramin kewayawa da sauri, kuma matsa lamba na ruwa yana tura ɓangaren rufewa don matsawa ƙasa da rufe. bawul. Ana siffanta shi da babban babba na kewayon matsi na ruwa kuma ana iya shigar da shi ba bisa ka'ida ba (don a keɓance shi) amma dole ne ya dace da yanayin bambancin matsa lamba na ruwa.
