Fault 1. Insufficient flow of frozen water pump:
The main cause of insufficient flow is a. impeller or water pipe blockage b. impeller damage is mainly solved by the following two methods a. cleaning the impeller or water pump b. replacing the impeller
Fault 2. When the cryostat is running, the low pressure is too low:
The occurrence of low pressure is mainly caused by the following reasons: a. The refrigerant is insufficient to only need to make up the leak, supplement the refrigerant or adjust the expansion valve, b. The filter is blocked and the filter needs to be cleaned or replaced. c. The expansion valve is too small. , properly adjust the opening degree of the expansion valve d. Capillary plugging of the cryostat as long as the capillary is cleaned or replaced;
Fault 3. The high pressure is too high during the operation of the cryostat:
The high pressure is too high during operation. Usually, the flow rate of a cooling water is too small or the water temperature is too high. Just increase the cooling water flow rate or lower the water temperature. b. Condenser copper tube/fin fins have more fouling and poor heat transfer effect. When the heat exchanger of the cryostat needs to be cleaned, there is too much refrigerant. When the refrigerant is too much, it is necessary to discharge the refrigerant. The expansion of the refrigerant d is too small, and only the expansion degree of the expansion valve needs to be properly adjusted;
Fault 4. Frosting of the return air pipe and compressor casing:
The frosting of the low temperature thermostat return pipe and the compressor casing is mainly caused by three reasons: a. The expansion valve opening degree is too large, b. The refrigerant is too much c. The heat load is too small. The solution is: a adjust the expansion valve b discharge Part of the refrigerant c increases the heat load or opens the bypass circuit of the frozen water circuit;
Fault 5. The low temperature bath can not be started or stopped immediately after starting:
The fault is usually caused by power failure or low voltage of the power supply. As long as the circuit fault is eliminated, the power supply can be supplied according to the low temperature thermostat. b. The thermostat is improperly set, so that the contacts are normally open, and only the temperature control set value needs to be re-adjusted. ; c cooling water is not open, the interlock circuit is disconnected, then only need to open the cooling system, turn on the interlock circuit can be protected after the protection device is not reset, press the stop button and then boot
Fault 6. The frozen water pump does not produce water:
The low temperature constant temperature tank freezing water pump does not discharge water mainly because a. water pump steering reverse b. impeller blockage mainly solves a. correct pump motor steering b. cleaning pump impeller;
