First, the solenoid valve coil burned out The phenomenon is that the low-voltage negative-value electromagnetic coil case has no thermal sensation, and is measured as a short circuit by the multimeter RX10. The solution is to replace the coil of the same type separately. Second, the spool is dead Third, oil plug, dirty block The phenomenon is cold feeling or frosting in the micro-blocking state until the full plugging and low pressure are low, which affects the refrigeration cycle. Fourth, the pressure controller does not produce action The phenomenon is (1) the electrical circuit is faulty or wrongly connected, (2) the electrical contact is pulled or stuck, (3) the mechanical action component of the cold storage engineering fails, (4) the oil plugging of the connecting pipeline, (5) no signal input, (6) ) There is a leak (11) The phenomenon is that the low-voltage negative-value electromagnetic coil case has no thermal sensation, and is measured as a short circuit by the multimeter RX10. To solve the cold storage maintenance method, the same type of coil can be replaced separately. Six, the closure is not strict The phenomenon is that the high and low pressures are quickly balanced during a period of parking. In the case of a world situation, there is sometimes a liquid appearing. The solution is to exchange the iron core.

The phenomenon is no opening and closing action, a. The low pressure is negative when the cold storage is installed in the closed position, and there is no refrigeration cycle. b. When it is in the open position, the high and low pressures are quickly balanced after parking, and it is easy to cause liquid when driving. The solution is to clean.
The phenomenon is not strict. The phenomenon is that the high and low pressures are quickly balanced during the parking period. In the world situation, sometimes there is liquid, and the solution is to exchange the iron core.
Out of control: The phenomenon is (1) the setting value is wrong, (2) the positioning is off, (3) the deformation of the mechanical component and the spring force variable value, (4) the high and low voltage signals are connected incorrectly, and the signal tube is deformed or bent to generate internal resistance, ( 5) Pressure controller remote cold storage refrigeration control system common fault analysis and treatment
Fifth, the solenoid valve coil burned out
The valve core is dead and there is no opening and closing action, a. The low pressure is negative when resting in the closed position and there is no refrigeration cycle. b. When it is in the open position, the high and low pressures are quickly balanced after parking, and it is easy to cause liquid when driving. The solution is to clean.
