Submersible pump pumping process should be noted that several points

Submersible pumping sand pump (sand pump) is a convenient operation, high efficiency, easy to damage, can work long hours pumping equipment. However, improper use will result in shortened pump life, the correct use and maintenance of the pump can greatly improve the working life. In use, should pay attention to the following points: 1, equipped with electrical starter protection High-power pumps need to start the device is generally divided into direct start, auto buck start, soft start, and frequency start, the customer should choose the right Start the way to start. Starters usually have over-voltage, over-current overload protection, poor power supply environment, or improper use caused by over-voltage, under-voltage, over-current, blocking pump, cut off the power and protect the motor. 2, should not be frequently turned off When the motor starts, the grid will cause a greater impact, while the pump itself is also damaged, should be used to avoid frequent start. 3, shut down the front row Although the road sand pump in the shutdown, please lift the pump slightly, with water pump and pipeline sand row row to prevent the backflow of sand by pairs of pump operation. 4, try to avoid the use of flat Because of the force structure, there is no description before ordering, the pump should be avoided using flat. 5, to prevent plugging Pumping pump is the most unpolluted pump in Shanghai, the normal use will not cause plugging pump, but some other external causes may also cause blocking pump, for example: landslide buried pump, long pipeline conveying high concentrated sand 6, the correct installation and installation Please follow the instructions required to install. 7, pump maintenance Check the consumable parts of the pump regularly, such as impeller, and add oil.
