Solenoid Valve Common Faults and Solutions
- DELCO Valve
Solenoid valve is a kind of valve to control the flow of gas and liquid through the action of electromagnetic force, which is widely used in the field of industrial fluid control. Timely detection of solenoid valve failure and maintenance to ensure the stability and safety of the production process has an important role. This article by DELCO Valve with you to discuss common solenoid valve faults and solutions.
How to determine whether the solenoid valve is open?
- Listen to the sound method: use your ears to listen to the solenoid valve whether the sound, if there is a sound is that the solenoid valve is open.
- Observe the light method: some solenoid valves are equipped with indicator lights, when the solenoid valve is on, the light will come on. Therefore, by observing whether the light is on, you can determine whether the solenoid valve is on.
- Detection of air flow method: for hydraulic or pneumatic solenoid valve, you can detect whether the air flow to determine whether the solenoid valve is open. In general, the use of fingers blocking the output port, if the hand feels the air flow, it means that the solenoid valve is open.
- The use of voltmeter method: for wired control of the solenoid valve, you can measure the voltage of the solenoid valve coil to determine whether the solenoid valve is open.
Solenoid valve common faults and solutions
Solenoid valve coil short circuit
Solenoid valve coil short circuit may be the unit heat exchange, due to short-circuit caused by excessive current burned coil. Detection of the fault method is to use a multimeter to measure the open circuit, is open, then the solenoid valve coil burned, the solution is to replace the solenoid valve coil.
Solenoid valve does not work
Solenoid valve power does not work may be loose or fall off the wiring, detection of this failure is to disassemble to see. The solution is to rewire, loose wire fastening wire.
Solenoid valve can not be closed
General solenoid valve valve sleeve and spool clearance is very small, when the solenoid valve internal foreign objects or insufficient lubricant, may lead to the solenoid valve can not be closed. Detection of this fault is to remove the solenoid valve, remove the valve sleeve and spool to see if there are foreign objects. Solution to clean with carbon tetrachloride, after cleaning the spool into the valve sleeve, so that the spool in the valve sleeve to run efficiently, there are throttle holes balance holes clogged should also be cleaned in a timely manner, such as the solenoid valve valve sleeve and spool or spring damage needs to be replaced with brand new parts.
Spool stuck
Spool in the process of use, due to improper use or other reasons, may be stuck, resulting in the solenoid valve can not be opened or closed. The solution is to disassemble the solenoid valve to clean or replace the spool.
