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　　 In addition, the use of ° and S-shaped bends should be reduced as much as possible during the installation and design of pipelines.Komitanchilo,　　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　　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, the cooling fan should be installed on the main shaft. It is also possible to appropriately increase the number of fan blades,KomitanchiloSubmersible slurry pump,　　Strong strength and other advantages. It is widely used as a sealing device for various pumps. Place a water seal ring at the bottom of the packing box, and then place the filler.　　When using the sand pump, be sure to pay attention to the steering divergence between the motor and the pump. The sand pump has an arrow on the pump to mark the main steering. After the power supply is connected, run the pump without load. Check whether the motor operates normally. During operation, forming an impact force. The metal surface of the pump was fatigued and damaged by these impacts. Cavitation is caused by air bubble rupture and material stamping due to the difference in air temperature and pressure

　　Let the medium containing some solid particles generate a certain flow rate so that the equipment can drive the solid to flow when it is in use, so that the slurry can be transported. In terms of the principle of the submersible slurry pump, there are many cases of sudden abnormal failures of submersible pumps. Among them, there are some common obstacles,KomitanchiloSmall deep well pump, such as the submersible pump cannot be started after it is powered on, or the motor speed cannot be started after the submersible pump is started. A very small wait　　 Before starting the submersible slurry pump, the rotor of the rotating pump shall be smooth and even, the outlet sluice valve shall be closed, and water shall be injected into the pump to ensure that the pump is full of water without air.Quality improvement,　　 If there is abnormal sound inside the slurry pump and there is no water, it is likely that the equipment may have air infiltrating into it when absorbing water, which will cause abnormal sound inside the pump, and then at the same time, the impeller is damaged or the impeller is damaged　　Discount. In order to meet the needs of industrial production and make the submersible pump to achieve the ideal use effect, accurate and reasonable selection is very important. In order to select the pump reasonably and correctly, the following aspects need to be considered: Selection of shaft seal form: shaft seal of submersible slurry pump　　Head refers to the energy obtained from the pump by the unit weight of liquid output by the pump, so head refers to the effective energy obtained from the liquid output by the pump in unit time - that is, the effective power of the pump: the equation is PE= ρ GQH (W)= γ QH (W)

　　 The secondary pump shaft seal of the two-stage series pump is (packing seal), and the startup of the series pump also follows the above method. Only after the first stage pump is started the submersible slurry pump can open the outlet valve of the last stage pump (the opening size is based on the motor current of the first stage pump as the rated powerassets,　　 drainage and water injection with vacuum equipment: the self exhaust of centrifugal pump is the same as the negative pressure exhaust of vacuum pump, so the water ring vacuum pump is used for exhaust to achieve the of water inlet.　　Secondly, let&#;s talk about the difference between WQ and QW sewage pumps.　　Balance of.Komitanchilo,　　Different process requirements: the motor used in the vertical slurry pump is an ordinary vertical motor, which has no waterproof . The motor of the submersible slurry pump and the pump shaft are coaxial. The motor shall be waterproof and sealed. The motor and the pump body can invade underwater at the same time.　　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,　　Many people do not know much about the packing and sealing of equipment because of the equipment of mass and energy. Next, let&#;s learn about the packaging and sealing method of the equipment: packing sealing is very common in submersible slurry pumps. This method has good sealing performance, is easy to use, and effectively reduces the wear of the host and anti vibration kinetic energy
