If the oil seal ring of the shaft is seriously worn, replace it with a new one.　　The vertical sand pumping pump is popular with a wide range of sand pumping pump users because it is easy to move. This equipment is made of high-tech endurance data. Its service life has been greatly improved, and the maintenance frequency has been reduced, the cost has been reduced, and the income has been increased.Brescia　　 before starting, check all circuits and switches to see if their wiring is correct and reliable, then turn them over the ground for ~ minutes (the time should not be too long to avoid damaging parts or burning motor windings), and check whether the motor running direction is correct. If the above problems are not found, it can be started　　Water flow into the bearing damages the bearing.Oskarshamn,　　Friction resistance due to bearing and packing; Friction between impeller and water during rotation; The vortex of water flow in the pump, gap reflux, inlet and outlet impact and other reasons. A part of the power must be consumed, so it is impossible for the water pump to completely change the power input by the power machine into effective power, when the submersible slurry pump is blocked during use, it will not only have a certain impact on the working efficiency of the equipment during operation, but also cause serious damage to the equipment itself, so it is also a reminder that we are using it too　　 The power line of the submersible sewage pump is relatively long, and the configured cable is relatively thin, so the voltage drop is too large, and it is difficult to start the submersible pump. A larger cable is required. If the distance is long, the submersible pump should be close to the transformer.　　 Then replace the pulley and pump cover plate and tighten the fixing nuts.Where is it,　　When in use, it can drive the impeller to rotate so as to drive it to flow.　　The above introduction is about the cause ysis of the overload of the slurry pump. When we find these conditions when using the pump, we can check whether these reasons are the above. This is also a reminder that we need to maintain the pump during normal use. latent　　Normal operation. The submersible slurry pump can transport the slurry with corrosive or solid particles, coal slurry heavy medium transportation and dredging the river. When the equipment is pumping sand, some sand layers around the equipment will make the equipment covered by a large amount of sediment, we should choose

　　Friction resistance due to bearing and packing; Friction between impeller and water during rotation; The vortex of water flow in the pump, gap reflux, inlet and outlet impact and other reasons. A part of the power must be consumed, so it is impossible for the water pump to completely change the power input by the power machine into effective power, in which the constant active powerresources,　　If the pump outputs more medium liquid, it will certainly do more work. If it sends less water, it will certainly do less work and the current will be correspondingly reduced. Pump power (kw) = head (m) × Flow (m/s) × The gravity of the fluid (kg/m for water) divided by (power conversion factor) divided by the efficiency of the pump (about　　Environmental conditions for normal operation of ordinary YLB motor:　　So it has a process of water diversion and exhaust. There are usually two ways to inject water into equipment. One is to directly inject water into the pump chamber,BresciaAh slurry pump,　　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.　　Third and the other is to pump out the gas in the pump to establish a certain vacuum and introduce the water source.Brescia,BresciaZD slurry pump,BresciaHH slurry pump, the whole industrial and mining system operates stably, the application market is also larger. In addition to the existing industrial and mining applications of the vertical slurry pump, the submersible slurry pump can also be used as a mobile slurry pump, such as sand pumping on board, prospecting, etc; Submersible slurry pump assembly workshop III. what are the advantages of submersible slurry pump
