Sanin tsarin zaɓi na solenoid valves a cikin tsarin huhu yana da mahimmanci don koyan ƙirar ƙira mara kyau!
Thesolenoid bawula cikin tsarin pneumatic shine ainihin abin da ke sarrafa jagorancin, matsa lamba, da yawan kwararar iskar gas. Zaɓin sa kai tsaye yana rinjayar aiki da amincin tsarin. Don ƙirar ƙira marasa daidaituwa, zaɓi na bawul ɗin solenoid yana buƙatar yin la'akari da ƙima da yawa kamar yanayin aiki, sigogin aiki, da dacewa. Mai zuwa shine taƙaitaccen tsarin ilimin zaɓi:
I. Ma'auni na Mahimmanci da Tushen Zaɓin Solenoid Valves
1. Matsakaici halaye
Shin iskan da aka matse ya ƙunshi mai, damshi, ko ɓarna? Kayan jikin bawul (irin su aluminum gami, bakin karfe, filastik injiniya) da kayan rufewa (NBR, FKM, PTFE) suna buƙatar daidaitawa.
Idan matsakaiciyar iskar iskar gas ce, ya kamata a zaɓi jikin bawul ɗin bakin ƙarfe cikakke tare da hatimin fluororubber.
2. Kewayon matsin aiki
Matsakaicin farawa: Kai tsaye - bawuloli masu aiki yawanci suna buƙatar Mafi girma ko daidai da 0.15MPa, yayin da matukin jirgi - bawuloli masu aiki na iya zama ƙasa da 0.01MPa.
Iyakar juriya na sama: Jikin bawul na al'ada na iya jure matsi na 1.0MPa. Don yanayin yanayi mai girma -, ya kamata a zaɓi takamaiman 1.6MPa ko sama.

3. Bukatar gudana (ƙimar CV / ƙimar Kv)
Yi ƙididdige ƙimar kwarara da ake buƙata dangane da saurin silinda kuma zaɓi bawul mai madaidaicin ƙimar Cv.
Q: Yawan kwarara L/min, D: Silinda diamita cm, L: Buga cm, P: MPa matsa lamba, t: lokaci s
Diamita na tashar bawul ɗin ya kamata ya zama mafi girma ko daidai da girman mahaɗar silinda don guje wa tasirin maƙarƙashiya.
4. Wutar Lantarki da Amfani da Wuta
DC (DC24V) ya dace da ƙarancin amfani da wutar lantarki da fashewa{2}} yanayin hujja. AC220V yana da arha a farashi amma yana da saurin zafi.
Ƙarƙashin wutar lantarki - ( ƙasa da ko daidai da 1.5W) na iya rage haɓakar zafi da tsawaita rayuwa.
5. Yanayin motsi
