Pneumatic solenoid valve hi kan siam chhuahnaah hian hman a ni nasa hle.A tlangpuiin pneumatic solenoid valve chu: 3 port 2 position, 4 port 2, 5 port 2 position, etc.Pneumatic solenoid valve failure hi a hnuaia thil atang hian enfiah tur a ni:
(1) Pneumatic solenoid valve wiring loose emaw off emaw a nih chuan pneumatic solenoid valve hi energized a ni lo.Hetiang a thlen chuan solenoid valve line kha check la, wiring kha i tichak leh ang.

(2) Solenoid valve coil chu a kang chhuak a, solenoid valve wiring chu lakchhuah theih a ni a, multimeter hmangin teh theih a ni bawk. Circuit chu a inhawng a nih chuan solenoid valve coil chu a kang chhuak ta a ni.A chhan chu coil chu a hnim a, insulation tha lo leh magnetic leakage a thlen a, chu chuan coil current chu a lian lutuk a, a hal chhuak a, chuvangin solenoid valve-a tui awm loh nan, spring chu a chak a, reaction force chu a lian lutuk a, coil turns pawh a tlem lutuk a, chu chu a manual a ni lo, a manual chu a kang thei a ni. Pneumatic solenoid valve hmangin pneumatic solenoid valve hawn theih a ni.
(3) Solenoid valve is stuck.Solenoid valve sleeve leh spool clearance te tak te (0.008mm aia tlem) nei, a tlangpuiin assembly pakhat a ni a, mechanical impurities into too light lubricating oil a awm chuan a stuck a awlsam a, treatment method chu head hole atanga steel wire chhunga hman theih a ni a, chutiang chuan a bulpui ber chu solen valve nen a bounce a, solen spool leh spool te chu a chhuak thei a ni. Cleaning, so that the spool in the valve sleeve action flexible.A chhe tawh chuan a then chu assembly sequence leh a part tinte pawn lam wiring position-ah ngaihven tur a ni a, chutiang chuan reassemble leh connect dik takin, oil spray hole chu a block em tih leh lubricating oil a tawk em tih enfiah tur a ni.
(4) Air leakage.Air leakage hian air pressure tling lo a thlen ang a, pneumatic solenoid valve hawn leh khar a harsa ang, he dinhmun hi sealing gasket tihchhiat emaw pneumatic solenoid valve piston wear emaw avanga lo awm a ni.Hetiang a thlen chuan a chhe lai te chu thlak tur a ni.
