The solution to the excessive temperature of the water pump: when selecting the motor, it is necessary to select one that matches its power and speed. In addition, the cooling fan should be installed on the main shaft. It is also possible to appropriately increase the number of fan blades, but pay attention to adjusting the vacuum pump　　Superior, complete protection s, reasonable structure, convenient installation and high cost performance. In case of sudden power failure of the plant and emergency, the water pump will automatically start to supplement the pipe network pressure.St. Louis ,　　The deep well pump works underwater. Taking Hengsheng deep well pump as an example, it has compact structure and light weight. It does not need too long transmission shaft to pump water from the underground. Deep well pump adopts waterproof measures such as mechanical seal or gas seal to keep the interior of the motor dry and free from water intrusion. Hengsheng pump today　　 Then replace the pulley and pump cover plate and tighten the fixing nuts.Toke ,　　 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.　　The purpose is to inject liquid higher than . MPa from the water seal ring to prevent gas leakage into the pump when the suction inlet of the submersible slurry pump is in a vacuum state. When the water pressure in the pump is higher than . MPa, the sealing fluid .-. MPa higher than the pressure in the pump can be injected to seal and reduce leakage　　 Structural features and working principle qsz submersible slurry pump is a coaxial integration of water pump and motor. During operation, the motor shaft drives the water pump impeller to rotate, and transmits energy to the slurry medium to generate a certain flow rate, drive the solid flow and realize the transportation of slurry.

　　 selection of flow: single suction pump or double suction pump shall be selected according to the flow; single suction pump or multi suction pump shall be selected according to the lift.　　 WQ series submersible sewage pump has fixed and mobile devices, as shown in the figure. When the fixed driving device is selected the chain cable shall be separately threaded into (away from the pump outlet, and its connecting line shall be parallel to the axis of the pump outlet) two lifting eye screws or lifting plates to lift the electric pump up and down,　　It should be /-/ between. When the packing is worn, the packing gland can be properly pressed. If it is worn too much, which are mainly to pay attention to the details and the phenomena occurred during the operation, and timely deal with the problems in time to avoid being on duty Accidents during operation cause losses.middleman,　　The other mechanical seal is a split seal, which can be replaced without disassembling the slurry pump.　　Rate.　　Superior, complete protection s, reasonable structure convenient installation and high cost performance. In case of sudden power failure of the plant and emergency, the water pump will automatically start to supplement the pipe network pressure.

　　 The fan speed of the water pump is too low, and the air pressure and air volume are relatively small, so the heat cannot be dissipated.quality index,St. Louis Deep well pump,　　If there is a standby pump, it is better to use two pumps in turn. If the pump is stuck, the pump can only be repaired. A net can be added at the water inlet to prevent too many impurities from entering the pump. In this way, the probability of pump sticking will be much smaller!　　The discharge side of the pump must be equipped with a valve (ball valve or stop valve, etc.) and a check valve. The valve is used to regulate the operating point of the pump. The check valve can prevent the pump from reversing when the liquid flows back (the long shaft deep well pumps produced by our company are equipped with anti reversing check devices) and prevent the pump from being hit by water hammer　　Then it can enter into the volute pump housing. Then in the volute pump casing,　　The non service life of the equipment is not as long as possible. If it is not used for a long time, it will not only easily corrode the parts, but also reduce the service life of the parts.　　 bind the exposed copper wire to the cable core evenly, heat it with an electric iron,St. Louis Submersible slurry pump, and infiltrate tin evenly.　　The water pump is not only the water supply for the city,St. Louis Submersible pump can pump sewage, 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, many people believe that
