The deep well pump is a kind of pump that is immersed in a groundwater well for pumping and transporting water, and is widely used in farmland drainage and irrigation, industrial and mining enterprises, urban water supply and drainage and sewage treatment. Because the motor is submerged in the water at the same time, the structural requirements for the motor are special than those of the general motor. The structure of the motor is generally divided into four types: dry, semi-dry, oil-filled and wet. This time, Shanghai Shenquan wants to explain to you the knowledge of the use of deep well pumps and precautions, so please follow and take a look.
Deep well pumps. 1. Before the installation and use of the deep well pump, the deep well submersible pump must be filled with clean water on the ground and then put into the deep well, and the pump should also be completely erected when irrigating, otherwise it will lead to the phenomenon of not being filled with clean water, which is one of the precautions for the use of the deep well pump, and it is also more likely to be used incorrectly.
2. After the deep well pump is placed in the deep well, the resistance of the deep well pump to the ground should be measured, and the resistance value should not be less than 5 trillion ohms.
3. The power supply voltage must reach the voltage specified by the deep well pump, otherwise it will lead to the phenomenon that the flow head parameters of the deep well pump cannot be reached, and the phenomenon of burning out the motor will occur in serious cases.
4. When the deep well pump is installed in the pool, the deep well pump must be kept upright, and cannot be tilted or used flatly, which is also the focus of the precautions for the use of the deep well pump.
5. The valve should be closed before the deep well pump starts, and then slowly open the outlet pipeline valve of the deep well pump after the deep well pump is started, and pay attention to the current to control the valve opening near the rated current of the deep well pump.
6. In the operation of the deep well pump, it is necessary to check whether the current, voltage and flow head are normal. If any indicator exceeds the rated value, it should be shut down immediately, and the cause can be found and solved before starting operation.
7. After the newly purchased deep well pump product is installed and put into operation for 4 hours for the first time, it should be stopped to measure the thermal resistance.
8. After stopping the operation of the deep well pump halfway, the next start, the interval between the two needs to be started after an interval of 5 minutes, mainly because the current is larger when the deep well pump starts, the motor is still hotter after the first shutdown, and the second starting current is large, and the temperature will rise more in order to prevent the temperature of the motor from being too high and the heavy water in the outlet pipeline.
9. Before stopping the pump, the outlet valve should be closed, the power supply should be cut off, and the switch box should be locked. When it is out of service in winter, the water in the pump should be discharged.
Well, the above content is provided by Shanghai Shenquan for you, I hope it can be helpful to you.
