1 a, failure phenomenon. Solenoid valve if not the reversing solenoid valve heart or slider not consciously, actively and fixed in one place, the air conditioner cooling or heating can not change each other. 8. on the capillarity is congestion or disconnect; Actuating the slider is not serious leak action or system. Common one of the most common fault is only more refrigeration, no heating, and actuating air-conditioner coolly said try our best to take care of, outdoor, indoor machine don't blow hot air, showing trouble light after downtime. 3. Electromagnetic valve slide block variant if the slider variant, even if the solenoid coil has electricity, pilot valve Industrial Valves core will not action, therefore causing the slider directional control does not reach the designated position, make the collusion inside the body, out compressor high pressure within the body into a short cycle, over the high temperature and high pressure, until more hot try our best to take care of, finally burn out compressor insulation. 5. System of high temperature, high pressure and machine contains impurities, moved the slider variant, jammed. 9. is memory is dirt, needle valve seat or valve is damaged and the spring force is too small, lead to solenoid valve closing is lax. In tightly sealed gasket and tighten screw. If refrigeration system pressure difference is too big, can't make the reversing valve reversing, is seizing refrigeration system pressure or search leaking points, and fill the refrigerant. Often expressed as not refrigeration, heating, or the effect not beautiful. For the whole system, by the high pressure to low pressure side leakage, reduce high/low pressure difference. 6. Remanence absorb heart valve or valve core is jammed, solenoid valve can not be closed when the power is cut off. Is in addition to the compressor in air conditioner refrigeration system process the most complex and most accurate devices, and seizing up more trouble and maintenance, difficult to judge, not easy to dispense with a device failure. In addition to curb the circuit fault common faults of valve core not action, congestion, leak from the slider movement or action does not reach the designated position, etc. Cleaning debugging, such as loss effect change. 4. Solenoid valve to install, actuating valve core is not action. 。 Should change as well. In addition, if the reversing valve inner leak, resulting in high suppress cooling gas leaked, to low voltage side can not make the reversing valve set up normal pressure on both ends of the piston, should change the reversing valve. Cleaning capillarity or USES a bit thick to disconnect capillarity of copper pipe welding. Cleaning and debugging or change the spring. If the four-way valve block is not action or action does not reach the designated position, seizing judgment may deem appropriate and use the screwdriver with wooden handle, tapped on the body, and keeps on or off the end flow 220 v power supply, repeated several times, heard a armature chorus and body gas reversing sound absorption, can distinguish the basic restore normal office concluded that reversing valve. Second, the fault comprised and dispense with 1. Coil of electromagnetic directional valve open circuit and short circuit or burn, valve core can not suck, moved the slider not action. The main valve, pilot valve and electromagnetic coil of three local. 3. Power supply voltage is lower than Marine solenoid valve fixed value, the electromagnetic valve of inlet pressure differential experienced more than open valve, the valve inside occasionally send out 'a little' noise, actuating valve core and can't do it. Should improve the power supply. 2. Solenoid coil short-circuit air conditioner change operation of the heating, electromagnetic Industrial Valves coil due to the short circuit current is too large, serious burn out on the main control board when the power wire or led brake before jumping movement, cause the machine can't normal office. Q: air conditioner electromagnetic directional valve common faults and dispense a: electromagnetic directional valve is a heat pump air conditioner refrigeration and heating office to change the magnetic control switch valve, belong to two four-way valve. 7. Solenoid valve tightly sealed gasket damaged or tighten screw relaxation, actuating refrigerant leakage. Should debug flow. Should be change. 2. Electromagnetic valve armature stuck, valve heart not consciously and actively moved the slider movement. Can open the valve cleaning debugging. Notes to the order: The national standard) A, A: B: product name, model, nominal size medium and temperature, pressure range C: whether there is attachment, delivery time, and special requirements so that we can correct selection for you.
