there is also a disadvantage of using the auxiliary impeller sealing system, which is generally about %. However it takes some energy on the auxiliary impeller of the submersible slurry pump, as long as the planning is reasonable, this part of the lost flow can be reduced. The slurry pump is mainly applicable to electric power, the pump and motor operate in a coaxial whole. When it runs, the motor shaft will drive the impeller of the pump to rotate, and then at this time, the rotating force can be brought to the medium, so thatKangjiqi,　　 Determination of lift　　Some impurities will entangle the impeller, so generally the open impeller will be used, so there is no need to worry about getting stuck in the process of transporting sewage.Maple-Ridge,　　Moreover, the leaked flammable, explosive and toxic liquid will cause fire, explosion and poisoning, and the consequences will be unimaginable.　　Generally, the diving depth of the submersible slurry pump is not more than meters, and the operation is reliable. Why not more than meters? This is the crucial technical point of the submersible slurry pump, because the current sealing technology in China is more than meters, not because the slurry pump has a problem, but because　　 Protective packing of shaft seal the shaft seal pump shall regularly check the sealing water pressure and water volume, keep a small amount of cleaning water flowing along the shaft, regularly adjust the packing gland, check the packing and regularly replace the packing. The shaft seal water pressure and water volume shall meet the above (shaft seal inspection) requirements.

　　Submersible slurry pumps generally need to use some composite materials for manufacturing when they are used,KangjiqiSingle stage slurry pump, so that they can have good wear and corrosion resistance when they are used, and can be used to transport most of the media when they are used. Phreatic slurry　　The working principle of the self-priming pump is to fill the pump casing with water (or there is water in the pump casing itself) before the pump is started. After startup, the impeller rotates at a high speed to make the water in the impeller channel flow to the volute. At this time, a vacuum is formed at the inlet to open the water inlet check valve. The air in the suction pipe enters the pump and　　 important parts shall be marked in advance to avoid errors during resetting. The joint surface and vulnerable parts shall be properly kept to prevent damage.Safety production,　　The vertical sand pump is generally a submersible slurry pump. Its main application method is that the motor and water pump can pump up the materials that need to be escorted when they are put into underwater mining.　　The production department has to spend a lot of money to maintain and update the pump every year. The pumps made of cast iron, bronze, rubber lining, stainless steel,KangjiqiCirculating hot water pipeline pump, titanium alloy and other materials used in China&#;s mining, chemical and water conservancy projects on the Yellow River are prone to wear, short service life and many faults　　The installation of submersible slurry pump is a step that needs to be concerned. Since we all care about it, it is mainly because the installation will directly affect the use effect. The installation work should be seamless. Some key operating points can be seen when installing the slurry pump.

　　Only in this way can its service life be extended to a large extent.plan,　　 important parts shall be marked in advance to avoid errors during resetting. The joint surface and vulnerable parts shall be properly kept to prevent damage.　　When it rises, the outlet pipe of the submersible sewage pump does not flow or does not flow. After relevant research and ysis, we believe that there are many reasons for the following abnormalities of the sewage pump.　　 The bus voltage where the motor is located is V. Due to the uneven cable voltage drop and load distribution, it is also possible that the temperature is too high due to the low voltage of the water pump.Kangjiqi,　　; In practical application, the submersible slurry pump is developing rapidly with its unique advantages. The vertical slurry pump needs to be fixed and installed in use, while the submersible slurry pump can be used directly without immersion, which is convenient and flexible.　　To repair the equipment. Submersible slurry pump is a machine used to transport liquid. It can be divided into many types according to different transport media. Then, when transporting some media with special properties the equipment will be treated with corrosion-resistant and wear-resistant process. Only in this way can the equipment be improved　　 When adding lubricating oil to the pump at ordinary times, the metering must be controlled, and the excess lubricating oil in the pump must be discharged and replaced regularly.
