Solenoid valve not unusual faults and solutions particular
Solenoid valves play a essential function in business pneumatic systems, permitting them to power the cylinders for reciprocating movement, enabling diverse automation capabilities. but, there may be a few commonplace disasters all through using solenoid valves, and information the causes and solutions of these screw ups is important to maintaining the ordinary operation of the gadget.
🔧 The coil is brief-circuited or disconnected
Detection technique: Use a multimeter to degree the on-off of the coil. If the resistance fee is near zero or infinity, it shows that the coil has a brief circuit or open circuit problem. If the measured resistance is regular (normally tens of ohms), a final take a look at is also required. area a small screwdriver close to the metallic rod threaded through the solenoid coil and energize the solenoid. If it feels magnetic, the coil is ordinary, in any other case it is horrific.
solution: If a hassle is detected within the coil, replace the solenoid coil.
🔌 Plug/socket problem
Symptom: when the solenoid valve is equipped with a plug/socket, the metallic spring of the socket may be broken, and the plug connection is incorrect (as an instance, the strength cable is mistakenly linked to the floor cable), ensuing within the energy cannot be transmitted to the coil. To keep away from those problems, it's far advocated to tighten the fixing screw after the plug is inserted into the socket and tighten the fixing nut after the coil is mounted on the spool rod.
treatment: check and accurate wiring errors, restore or replace damaged plugs and sockets.
🧠 The valve center is defective
Fault phenomenon: inside the case of normal stress of the medium thru the solenoid valve, press the crimson manual button of the solenoid valve, and the solenoid valve does no longer have any response (the pressure medium does now not change on or off), indicating that the spool ought to be bad.
treatment approach: to start with, test whether or not there are issues within the medium, along with whether there is lots of water in the compressed air (from time to time the oil-water separator does now not play a completely big position, specifically while the pipeline is poorly designed, the compressed air through the solenoid valve can be
