Limited. According to relevant materials, the diameter of the impeller after cutting shall not be less than % of the diameter of the standard impeller,NarinWQ submersible sewage pump,NarinSingle suction slurry pump, otherwise the of the pump will have a very adverse change. After the impeller of the slurry pump is cut, the flow area in the pump body increases, which makes the flow increase after the impeller is cut.　　Yes, summer is the peak sales season. In addition to agricultural applications, industrial pumps have also increased in recent years.Narin,　　 The variable speed operation of screw pump is used in sewage plants. Screw pump is generally used together with sludge dehydrator. Whether it is to transport sludge to be treated or flocculant, 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 sealBat Yam　　 Then unscrew the nut at the front end of the pump shaft, remove the cover plate, and press out the middle impeller and water seal.　　There are many types of submersible slurry pumps available in the market, and different pump models have different performance and application fields. Therefore, although the pump has a wide range of applications, if its model is not correctly and reasonably selected, flow and liquid delivery. The flow range of the delivered liquid is - L / s the pressure range is .- MPa, and the diesel engine speed range is - rpm. Features: water pump, high automation and performance

　　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　　Extractable.　　When this type of pump is used at ordinary times, 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 thatdiscount,　　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.　　The fruit is also bad; When the axial flow pump is used, its water output is relatively large, so the effect of using the submersible slurry pump in many plain areas is also relatively good; The water output and head of the mixed flow pump are actually derived from one　　About %), and motor power p=i × U indicates that high power and current will increase.

　　After meters, the sealing of the equipment can not bear the water pressure at this depth.Pursuit of excellence,　　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 power　　 altitude of pump installation site M　　 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.Narin,　　After that, before starting again, check whether the impeller rolling is normal and whether the bearing assembly compression bolts are tightened, and then start the pump.　　Limited. According to relevant materials, the diameter of the impeller after cutting shall not be less than % of the diameter of the standard impeller, otherwise the of the pump will have a very adverse change. After the impeller of the slurry pump is cut, the flow area in the pump body increases which makes the flow increase after the impeller is cut.　　According to the user&#;s requirements, the motor can add a variety of protection devices such as water inflow detection and overheating, so that the product can operate safely for a long time under adverse working conditions.
