Sendai AirportWQ submersible sewage pumpHow to play a practical role

　　The submersible slurry pump may be blocked when it is used at ordinary times. In particular,Sendai AirportUsed pipeline pump, some equipment is frequently used at ordinary times, but the maintenance work is not done well when it is used,Sendai AirportFire deep well pump, so it will be blocked after being used for a period of time　　When the submersible slurry pump is used at ordinary times, cavitation usually occurs, which has a great impact on the impeller of the equipment itself. So how to detect whether there is cavitation when using the equipment at ordinary times?Sendai Airport,　　 Check the water pump: it is possible that the selection of the water pump is not matched with the motor, which makes the temperature of the motor too high after long-term operation; It is also possible that the working time exceeds the specified working time of the motor. At this time, the use time and times should be strictly limited the correct thermal protection should be selected, 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.Waregem,　　Where ρ—— Density of transmission medium liquid (kg/m; γ—— Gravity of medium liquid (n/m; H -- pump lift (m); Q - water pump flow (m/s); G - gravitational acceleration (m/s.　　The difference between the shaft power P and the effective power PE is the power loss in the pump, which is measured by the pump efficiency. The pump efficiency is the ratio of the effective power and the shaft power, which is measured by η Indicates.　　The input quantity is related to many factors such as the rotating speed of the submersible slurry pump, the continuous working time, the number of stops and starts of the pump, the surrounding environment and the working temperature. Therefore, it is likely that the equipment may have air infiltrating into it when absorbing water which will cause abnormal sound inside the pump, and then at the same time, the impeller is damaged or the impeller is damaged　　Then start the spray pump. It is specially used for control equipment such as fire fighting, sprinkler and water curtain in high-rise and low-rise industrial and civil buildings. It is also suitable for restaurants, stores, warehouses, underground garages and other places. The ordinary sprinkler head can be directly installed or hung on the sprinkler pipe network　　When the pump is not in use, the pump shall be lifted away from the water source in time to drain the accumulated water in the pump, especially in cold winter. Then put it in a dry place. Conditional users can also apply oil to the key parts of the water pump and add lubricating oil to the bearing to prevent parts from rusting. in additionHonesty and mutual benefit,　　Sex is different. Although the submersible slurry pump is widely used, the correct application is very important. Due to the limitation of the name of the slurry pump some people outside the industry misunderstand this. In fact, the impurity pump, dredging pump, desilting pump, etc. are all in the application scope of the slurry pump　　 for screws that are too tight or rusted for a long time, the nut can be lubricated with kerosene prepared in advance, or the nut can be gently knocked with a wooden hammer and then removed. This method can also be used in slurry pumps and other places.　　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.

　　In addition to the method, materials shall be selected comprehensively according to the nature of corrosive medium, anti cavitation theory, corrosion mechanism of water pump and stress characteristics. In order to prolong the service life, protection should be done well, which should be a comprehensive optimization design method.Industry management,　　When using the submersible slurry pump, we should do a good job in all aspects of commissioning and precautions. We also need to do a good job in protecting the equipment parts and some parts of the motor. Only in this way can we avoid the impact of water and other impurities entering the motor　　The horizontal slurry pump is a cantilever centrifugal slurry pump, which is suitable for conveying abrasive or corrosive slurry. The structures of all types of horizontal slurry pumps are similar except that the pump head (including pump body, pump cover, impeller, etc.) has different structures. The pump head part, shaft seal part and transmission part　　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.Sendai Airport,　　Reasonable.　　In the application of pumps, the first thing we think of is water. Whether it is drinking water or coefficient water, 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.　　Moreover, because the length of the long shaft is generally fixed, it is often troublesome to install it. Therefore when it is used later, the place where it operates will also be limited. If the equipment will
