How to Detect the Quality of the Solenoid Valve Ⅰ?

The quality of the solenoid valve mainly depends on two aspects, one is the coil and the other is the valve body, so the test is mainly to test these two aspects. You should find a 24V power supply and connect it to the coil. , Indicating that the solenoid valve and valve core are normal, can be sucked normally, and then check for leaks if there is an air source, it is best to directly connect the air source, you can determine whether the air leaks, if not Source, you just plug the air outlet and blow it down. In addition, the coil can be checked with a universal meter. Pulse Valve Supplier shares with you.

1. Unplug the solenoid when it is energized, and measure whether there is electricity with a multimeter. 2. Use a thin steel wire to close the coil to energize the solenoid valve to see if there is suction. 3. Power on - the power of a reverse retest of the solenoid valve, poke the brass "small pit" on the solenoid valve axis with a very thin Allen wrench to see if it can be sucked in and popped out.

Method to detect the quality of the solenoid valve:

First apply the controlled medium to the solenoid valve (liquid, gas <air> with pressure, the pressure value is the middle value of the pressure range of the solenoid valve), and then energize the solenoid valve coil. Or the change from off to on state, then the solenoid valve is good, otherwise, it is problematic.

Common faults of solenoid valve:

1. Coil short circuit or open circuit:

Detection method: first measure the on-off with a multimeter, the resistance value approaches zero or infinity, which means the coil is short-circuited or open-circuited. If the measured resistance is normal (about tens of ohms), it cannot be said that the coil must be good. Everything is normal after replacing the coil. Please perform the following final test: find a small screwdriver near the metal rod worn in the solenoid valve coil, and then energize the solenoid valve. If you feel magnetic, the solenoid valve coil is good, otherwise, it is bad.

Solution: Replace the solenoid valve coil.
