Hot and hot temperatures gradually began to happen every day. Vehicles can better ensure the normal operation of their air-conditioning systems. Only in this way can the drivers of bulk feed trucks work in a relatively cool environment. What should happen if the air-conditioner of the vehicle is broken? What? We first carefully examined and implemented the corresponding solution. I. Insufficient output of air conditioning in air conditioners for bulk feed trucks First of all, we should first check if the air intake is closed. Heat sink and condenser coil need to be cleaned. Whether the air-conditioning refrigerant needs to be added and whether the operation of the blower motor is checked for malfunction. Evaporator, filter element and air duct are not blocked by dirt. If the pressure value displayed by the high-Pressure Gauge is normal, but the low-pressure gauge value is the displayed high pressure, then the adjustment of the evaporator pressure regulator, the air intake throttle valve and the hot gas bypass valve is proved to be improper or there is malfunction. If the temperature of the air discharged by the air conditioner is relatively high, but the pressure value of the pressure gauge is low, high, or normal, then the expansion valve strainer is blocked. If the value of the high-pressure meter is greater than the normal pressure value, the low-pressure meter is lower than the normal pressure value, but the pipeline and the date dryer appear frozen, then the filter of the date dryer is blocked. . Second, bulk feed truck air-conditioning air conditioning intermittent. First of all, you should check the switches and circuits of the lower fan to see if the fan's motor has failed. Solenoid valve and compressor coil have bad grounding or open circuit, or loose connection. Check for loose connections in the compressor connection. There is no blockage in the evaporator. If the low pressure value of the low pressure gauge is too low and too high, the thermostat does not work properly, then the thermostat has a malfunction. If both the high pressure gauge and the low gauge gauge show low pressure values, then there is moisture in the system, which blocks the suction throttle valve or the hot gas bypass valve. Third, the bulk feed truck air conditioning without cooling air. Check if the connecting wire is disconnected and the fuse is blown. The compressor's drive belt has not broken or loosened. The thermostat's electrical contacts and temperature sensing elements have failed. Compressor coupling coils and solenoids are in the normal field. Whether the original air conditioning system components and refrigerant piping and compressor seals have leaked. If there is hot water in the heater and the evaporator is releasing hot air, then the operation of the heating valve has failed. If the engine is at any speed, and the value of the high pressure gauge and the low pressure gauge only slightly change, then the compressor's tongue valve has failed.
