.　　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.Pepper,　　Finally, select the appropriate pump model according to the determined Q and H. It should be noted that in the actual selection, in principle,PepperPipeline pump, the pump model closest to the intersection of the pump performance curve and the device performance curve should be selected, and the best operating point of the pump should be in the high-efficiency area of the pump efficiency curve as far as possible.　　First, let&#;s talk about the familiar vertical slurry pumps. Here we refer to ZJL and SP submerged slurry pumps. Strictly speaking, the submersible slurry pump is also a vertical slurry pump, because its axis is basically vertical when it works, but it can be completely immersed in water when it runs, so it is a good choiceRedcliff,　　During normal operation, some even as high as ℃. In this case, it is easy to burn the motor and replace it with a new one. In fact, one motor burns out at this time. Don&#;t worry about replacing it. You must find out the cause of the motor&#;s heating, or　　 It is also possible that the fan blades of the pump are few and the air volume is insufficient, resulting in poor heat dissipation effect.　　The Tao part also consumes part of it.

　　Screw it down,PepperZD slurry pump, and then remove the bearing inner race, O-ring, shaft sleeve and retaining sleeve in turn.　　Compared with the investment in purchasing cf fire control cabinet, there is no need to build complex ground protection and fixed devices,PepperDouble suction slurry pump, and the management is easier. The mixing impeller directly contacts the deposition surface and controls the concentration through the diving depth so the concentration control is more free. Equipment directly submergedoriginal,　　 Then replace the pulley and pump cover plate and tighten the fixing nuts.　　Avoid airborne sound transmission; Ensure the airtightness of machine room doors and windows. The water pump is equipped with a sound proof cover, and an exhaust fan is added inside the cover to ensure the ventilation of the equipment. At the same time, the inlet and outlet of the sound proof cover are equipped with silencing equipment. A vibration isolation platform is installed at the bottom of the water pump for foundation vibration reduction to isolate the vibration generated during the operation of the water pump　　 Selection of pipeline diameter: the selection of pipeline shall consider the one-time purchase cost long-term operation cost and operation reliability.

　　Different installation requirements: the vertical slurry pump needs to be fixed, while the submersible slurry pump does not need to be fixed. It can directly invade into the liquid for operation.Free consultation,　　 The submersible slurry pump usually relies on water cooling to dissipate heat. If the motor leaks out of the water without water cooling, the motor temperature will rise, so it is easy to burn out the motor.　　 Remove the wire guard, water strainer and cut the cable from the lead and the three core cable or flat cable connector.　　 Pipeline layout: Firmly support the water pipe and drain pipe to prevent the force of the pipe from acting on the submersible slurry pump.Pepper,　　The direction of the differential pressure force is opposite, which can offset part of the axial force and prolong the service life of the bearing.　　 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.　　We also need to limit the starting frequency and select appropriate thermal protection devices for use.
