In laboratories, pumps are one of the commonly used devices to transport liquids, gases, or other substances. Whether the pump is in normal working condition directly affects the conduct and results of the experiment. It is very important to determine whether the laboratory pump is working properly.
1. Observe the appearance of the pump.
First, observe that the appearance of the pump is intact and that there is no visible damage or wear. Check that the connecting pipes of the pump are firm and that there is no loosening or air leakage.
2. Listen to the sound of the pump.
A properly functioning pump should emit a smooth, noise-free sound. Abnormal sounds emitted by the pump, such as sharp friction sounds, shrill whistling sounds, etc., are damage or loosening of the internal parts of the pump.
3. Check the vibration of the pump.
The pump should remain smooth and free of noticeable vibrations during operation. Pump vibration is due to loose or damaged internal parts of the pump, or poor pipe connections, etc.
4. Check the inlet and outlet pressure of the pump.
The inlet and outlet pressures of the pump should remain stable without significant fluctuations in normal operation. Abnormal fluctuations in inlet and outlet pressures may be due to damage or blockage of the pump's internal components, for example.
5. Check the flow rate and head of the pump.
The normal operation of the pump flow and head should meet the design requirements. Insufficient flow or head can be due to damage or blockage of the pump's internal components, etc.
6. Check the temperature and humidity of the pump.
The temperature and humidity of the pump for normal operation should be kept within a reasonable range. If the temperature is too high or too low, it is due to damage or blockage of the internal parts of the pump, etc.
Judging whether a laboratory pump is working properly requires inspection and evaluation from several aspects. If any abnormalities are found, measures should be taken to deal with them in time to ensure the smooth progress of the experiment and the accuracy of the results.
