　　Stability and reliability of seals between pump bodies.　　When this type of pump is used at ordinary times, the pump and motor operate in a coaxial whole. When it runs, and then at this time, the rotating force can be brought to the medium, so thatOberville,　　 Assembly of water pump: fix the shaft and water inlet joint on the mounting base, and then install the guide housing and impeller In this way, the upstream casing and check valve are installed in turn.　　The supply of shaft seal water must be ensured. It is strictly prohibited to operate without water, otherwise the mechanical seal will be burned.Wadenswil,　　 selection of pump head: generally, the pump head shall be determined by enlarging the margin of % - %.　　 Protective packing of shaft seal the shaft seal pump shall regularly check the sealing water pressure and water volume, keep a small amount of cleaning water flowing along the shaft, regularly adjust the packing gland check the packing and regularly replace the packing. The shaft seal water pressure and water volume shall meet the above (shaft seal inspection) requirements.　　Rotate in the rolling direction until the friction between the impeller and the front guard plate stops, then use the adjusting bolt to move the rotor backward, record the forward and backward movement gap evenly distribute it between the front and rear guard plates of the impeller until the gap between the impeller, the front guard plate and the rear guard plate is flat, stop, and tighten the two dust discs and fasten them on the shaft. adjustment

　　Stop, then tighten the bearing seat, and fix the axial position of the rotor. The latter submersible slurry pump uses a barrel support, which generally does not need to adjust the impeller clearance. Therefore, if there is a problem with the clearance in the future use, loosen the support clamp first, and say that the nut is loose　　Unchanged.　　Troubleshooting: first increase the water pressure,ObervillePipeline pump, then inject water into the pump body, and then start the pump. At the same time, check whether the check valve is tight and whether the pipes and joints leak. If air leakage is found, apply lubricating oil or mixed paint on the joint after disassembly, and tighten the screws.agent,　　Now you know the reason why the pump has air turbidity. In fact, this is a very common phenomenon. You don&#;t have to worry about it. Water pump can transport many things such as water, oil, liquid metal, acid-base night and so on. It is a good means of transport.　　Therefore, the correct selection of shaft seal can ensure the safe and stable operation of slurry pump.　　 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.

　　If the submersible slurry pump cannot be installed and operated,　　The water pump is not only the water supply for the city, but also the household water purifier used in our home. There is a with pump equipment to help us purify water. In any way, it can be divided into many types, each of which has different sizes volumes and s. Therefore, many people believe that　　QW (WQ) submersible non blocking sewage pump shall be carefully inspected before operation? Whether the cable is damaged, whether the fastener is loose or dropped, and whether the pump is deformed or damaged during transportation, storage and equipment.　　What is the order.Oberville,　　If the oil seal ring of the shaft is seriously worn, replace it with a new one.　　Troubleshooting: first increase the water pressure, then inject water into the pump body, and then start the pump. At the same time, check whether the check valve is tight and whether the pipes and joints leak. If air leakage is found,ObervilleBaigang deep well pump, apply lubricating oil or mixed paint on the joint after disassembly,ObervilleWQ submersible pump parameters, and tighten the screws.　　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
