Pneimatisko solenoīda vārstu plaši izmanto mūsu ražošanā . Parasti pneimatiskais solenoīda vārsts ir: 3 2. ports, 4 ports 2 pozīcija, 5 portu 2. pozīcija {. Pneimatiskā solenoīda vārsta kļūme jāpārbauda no šādiem aspektiem:
(1) Pneumatic solenoid valve wiring loose or off, pneumatic solenoid valve is not energized.When this happens, you should check the solenoid valve line and reinforce the wiring.

(2) Solenoīda vārsta spole ir izdedzināta, solenoīda vārsta vadu var noņemt un izmērīt ar multimetru ., ja ķēde ir atvērta, solenoīda vārsta spole ir izdedzināta . Iemesls ir tas, ka spole ir mitra, un tā ir pārāk liela izolācija un magnētiska noplūde, kas izraisa to, kā tas ir izveidots. solenoid valve.In addition, the spring is strong, the reaction force is too large, the coil turns are too few, the suction is not enough can also make the coil burned.In case of emergency, the manual button on the pneumatic solenoid valve can be operated to open the pneumatic solenoid valve.
(3) Solenoīda vārsts ir iestrēdzis {. Solenoīda vārsta piedurkne un spole ar ļoti nelielu klīrensu (mazāk nekā 0 . 008mm), parasti ir viens komplekts, kad ir mehāniski piemaisījumi, kas ir pārāk mazi eļļā, kas ir viegli iestrēdzis. back.The fundamental solution is to remove the solenoid valve, remove the spool and spool sleeve, with CCI4 cleaning, so that the spool in the valve sleeve action flexible.When disassembling, attention should be paid to the assembly sequence and external wiring position of each part, so as to reassemble and connect correctly, and check whether the oil spray hole is blocked and whether Pietiek ar smēreļļas.
(4) Air leakage.Air leakage will cause insufficient air pressure, making it difficult to open and close the pneumatic solenoid valve, this situation is caused by damage to the sealing gasket or wear of the pneumatic solenoid valve piston.When this happens, the damaged parts should be replaced.
