Low temperature coolant circulation pump is one of the equipment that provides low-temperature coolant for experiments and other work under low temperature conditions. It has the characteristics of small volume, high work efficiency, and easy operation. In order to ensure the stable operation of the low-temperature coolant circulation pump, the editor will introduce the operating procedures of the low-temperature coolant circulation pump.
1、 Preparation before use
1. Before use, it is necessary to clean the oil stains on the low-temperature coolant circulation pump to prevent impurities, oil stains, and other substances from entering the interior of the low-temperature coolant circulation pump and affecting its service life.
2. Before use, it is necessary to check whether the various fastening parts of the low-temperature coolant circulation pump are firm to prevent loosening during use.
3. Before use, it is necessary to fill the water tank of the low-temperature coolant circulation pump with water because the less air in the tank, the more stable the operation of the low-temperature coolant circulation pump.
2、 Start and Stop
1. Start up: First, plug in the power plug and turn on the power switch. Then, press the opening button to turn on the motor switch, allowing the low-temperature coolant circulation pump to start running. When there is stable low-temperature liquid flowing out of the pump outlet, it indicates that the pump has started.
2. Stop: Press the drain button to turn off the motor switch, then turn off the power switch, wait for the motor to stop running, and then unplug the power plug.
3、 Precautions during operation
1. Do not open the action scale of the low-temperature coolant circulation pump during operation to prevent the inlet from being blocked.
2. If the pump is stopped, immediately cut off the power and release the valve.
3. Do not attempt to loosen fasteners when the low-temperature coolant circulation pump has not completely stopped running.
4. If there is noise or other abnormal situation during the operation of the low-temperature coolant circulation pump, it should be stopped in time and the fault should be eliminated.
