Cryogenic Cooler For Sale

The protective device of the cryogenic cooler has the following four points:

1. Oil pressure difference protection: It is used for compressors with oil pump to prevent the oil pump from not oiling, affecting the lubrication of the compressor and causing the cylinder unloading mechanism to not work normally. Protection method: Use the oil pressure difference controller to detect the oil pressure difference between the inlet and outlet of the oil pump. If the oil pressure difference lasts for about 60g and fails to reach the normal value (about 0.15MPa), stop the compressor.

2. Suction and exhaust pressure protection: mainly to prevent the suction pressure of the compressor from being too low and the exhaust pressure from being too high. With the pressure controller, when the suction pressure and exhaust pressure reach the warning pressure value, the compressor will stop running.

3. Cooling water jacket cut-off protection: The cylinder head of the ammonia compressor is equipped with a cooling water jacket to apply external cooling to the compression process. The cooling water cut-off protection control of the water flow relay seat, if the continuous cut-off reaches the specified time, the compressor will be controlled to stop. In the refrigeration system that uses the refrigerant liquid pump to force the liquid supply cycle to the evaporator, if the pump does not run overnight, it will cause cavitation damage to the refrigerant liquid pump and burn the motor. Use a differential pressure controller to detect the fluid pressure difference between the front and back of the pump. If the pressure difference continues for 8-15 seconds and cannot reach the normal value, the pump will be controlled to stop running.

4. Compressor exhaust temperature and oil temperature protection: prevent the exhaust temperature from being too high, and the oil temperature from being too low or too high. Use a temperature controller to stop the compressor when the above temperature reaches the warning value.
