In the application of pumps, even the polluted water in cities needs to be purified. All these require its equipment to provide services for us. Without pumps, our basic survival is a problem.　　Do not exceed the rated current.Kuchowe,　　In order to improve the effect of the fire pump and achieve the purpose of timely guarantee. Control the operation, startup and shutdown of all fire pumps through the fire control cabinet, which can greatly improve the efficiency of fire pumps.　　Work, no noise and vibration,KuchoweCirculating hot water pipeline pump, and the site is cleaner.Jacobabad,　　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 seal　　The packing seal auxiliary impeller seal and mechanical seal are mainly used. Among them, the packing seal needs small leakage and is not suitable for transporting toxic, corrosive and precious liquids; The sealing of the auxiliary impeller relies on the reverse pressure of the two sealing impellers during rotation to prevent the leakage of the medium, and can also play a role in　　The seal cannot bear the water pressure at this depth. Once the water leaks,KuchoweAh slurry pump, the motor will not work normally, resulting in damage to the submersible slurry pump. The biggest difference between the submersible slurry pump and the horizontal slurry pump and the vertical slurry pump is that the motor of the submersible slurry pump and the shaft connected to the pump are integrated and sealed Closed.

　　Promote the continuous expansion of the sales network group.　　 Determine the head h. After the flow is determined, determine the inlet and outlet pipe diameters of the pump, complete the layout of the whole pipeline, and determine the head. In the actual selection, the resistance coefficient of the pipeline is often too large. In addition, when selecting the pump model,KuchoweScrew deep well pump, a head margin is added, 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.where,　　 strip the outer layer of the cable to expose the copper wire for to mm, gradually thin the rubber near the wire core, grind it to the oxide layer on the wire core, wipe the wire core with alcohol (or hydrochloric acid), wrap the insulation layer and sheath layer, and dry it naturally.　　 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.　　With water, you can start working.

　　 The rotor assembly is designed according to the actual situation, and the operation is more stable!Analysis project,　　 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.　　 Pressure control: external electric contact pressure gauge or pressure controller can automatically turn on and off the pump according to the change of pipe network pressure. This type is widely used in domestic water supply and fire pressurization systems.　　; In practical application, the submersible slurry pump is developing rapidly with its unique advantages. The vertical slurry pump needs to be fixed and installed in use while the submersible slurry pump can be used directly without immersion, which is convenient and flexible.Kuchowe,　　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, so the concentration control is more free. Equipment directly submerged　　 We also need to make choices according to local conditions when we make purchases at ordinary times. For example, the head of the centrifugal pump itself is relatively high, but its water output is not very large when it is used, so it is effective when it is used in many mountainous areas　　 First of all, multiple pumps need to be used in parallel or standby pumps need to be prepared.
