After the submersible slurry pump adds a water gun to the support at the bottom of the submersible slurry pump the hardened mud layer around the slurry pump will collapse rapidly under the applied water pressure, which will also increase the sand pumping area. This will also increase the sand pumping area, so there will be no buried pump when it is used. However,　　Some of them are OK. For irrigation and other purposes, in fact, we choose to use larger flow. Let&#;s take a look at the method of selecting pumps.Ashksham,　　 Working conditions　　 The working properties of the two pumps are also different. Because the sewage pump is driven by a motor, it generally has good voltage impact resistance. The submersible pump is of the type of quick opening and quick closing, so it usually uses some small Flow and small pressure.Torehondyardos,　　The purpose is to avoid water leakage of the pump, but the water seal may be damaged due to faults after being used for a period of time. Let&#;s learn how to replace the water seal.　　 If the head of the submersible slurry pump is too low or the head is higher than the practical condition, the flow will be large and the current will rise. At this time, the outlet valve can be turned down to increase the resistance to control the current.　　 the water pipe shall be provided with a gate valve to regulate the pump working point. The valve shall be installed as close to the pump outlet as possible. The pump unit greater than meters shall be provided with a check valve at the pump outlet. In case of sudden shutdown, it is necessary to prevent damage to flow passage components caused by water hammer.

　　The motor is scrapped. Moreover, because the length of the long shaft is generally fixed, the installation and use of the pump is troublesome, and the application occasions are subject to many restrictions.　　The submersible sewage pump is mainly used to ensure various sewage pump products containing solid particles or other impurities. Because it works in water, we call it a submersible sewage pump, and the model selection of the submersible sewage pump is often determined according to the parameter information such as the nature and working characteristics of the sewage pump station.　　Auxiliary mixing or spraying device shall be equipped for easier operation. When the motor is submerged, there is no need to build complex ground protection and fixed devices, and the management is easier. The mixing impeller directly contacts the deposition surface and controls the concentration through the diving depth,　　 There may also be mechanical failure of the pump, such as serious damage to the bearing of the pump, or the impeller will be stuck due to impurities such as water and grass when the pump pumps water　　 The working properties of the two pumps are also different. Because the sewage pump is driven by a motor, it generally has good voltage impact resistance. The submersible pump is of the type of quick opening and quick closing, so it usually uses some small Flow and small pressure.　　 the water pipe shall be provided with a gate valve to regulate the pump working point. The valve shall be installed as close to the pump outlet as possible. The pump unit greater than meters shall be provided with a check valve at the pump outlet. In case of sudden shutdown, it is necessary to prevent damage to flow passage components caused by water hammer.

　　The pump should be divided into two aspects: electricity and machinery. As for machinery you can compare the previous maintenance records. The second is electricity. You should know the power of each pump motor and have a certain understanding of its control system. Slurry pump with mechanical sealProduct survey,　　After the submersible slurry pump leaves the factory,AshkshamVertical centrifugal slurry pump, there is generally only outgoing cable, and the user needs to connect it separately during installation. If the connection is wrong it will seriously affect the normal operation of the pump, so we should follow the correct steps to connect.　　Slide evenly and slowly along the guide rail until the active coupling is in place. When the mobile device is selected, the hose shall be sleeved first,AshkshamVertical heavy-duty slurry pump, and the chain rope shall be threaded into the two lifting rings to lift the electric pump up and down. Be careful not to use the cable as a rope to avoid danger.　　Second, the service life of the flow passage parts of the pump is relatively long, saving production costs.Ashksham,　　Water or air leakage in the pipeline. The nut may not be tightened during installation. If the leakage is not serious, the air or water leakage can be treated with cement or cement slurry mixed with asphalt oil. Temporary repairs can be done with some wet mud or soft soap. If water leaks at the water pump joint, tighten the nut with a wrench. as　　Causes: there is air or gas accumulation in the water inlet pipe of the pump, or the bottom valve is not closed tightly,AshkshamSubmersible sewage pump, the water supply is not satisfied, the packing of the vacuum pump leaks seriously, and the gate valve or flap valve is not closed tightly.　　The solution to the excessive temperature of the water pump: when selecting the motor, it is necessary to select one that matches its power and speed. In addition, but pay attention to adjusting the vacuum pump
