READ MOREWhat are the faults of single-head solenoid reversing valve?
Common faults of single-head electromagnetic reversing valves mainly include unreliable commutation, coil failure, leakage problems, shock and vibration, and installation and assembly problems, as follows: Unreliable commutation or inability to commutate: Electromagnet problems: Burned out electromagnet coil, insufficient electromagnet driving force or magnetic leakage, electrical circuit failure, etc., may cause the electromagnet to fail to work properly, thereby affecting commutation. For example, a coil short circuit or open circuit may be caused by coil quality problems, excessive power supply voltage, repeated shocks, or excessive mechanical vibration. Pilot solenoid valve failure: the valve core and valve body hole are stuck, the spring is bent sideways, etc., which may also lead to unreliable commutation. This is usually caused by poor geometric accuracy of the parts, tight fit between the valve core and the valve hole, or excessively dirty oil. The main valve core is stuck: The geometric accuracy of the valve core and the valve body is poor, the valve core and the valve hole are too tight, there are burrs on the valve core surface, or there is no oil in the control oil line, etc., which may cause the main valve core to be stuck, thus affecting the direction change. Other factors: if
