　　 Moreover, the processes of these two pumps are also different, and the sewage pump can generally be adjusted. Submersible pumps are generally used in some special or other places.　　 determination of model: for water pump or pump with physical and chemical medium similar to water, it is necessary to go to the relevant product catalog or sample, and make correction according to the performance table or performance curve of the model to see whether the normal working point falls in the priority working area of the pump.St. Mikel　　 The pump without self circulation cooling device shall not be exposed to the water surface for a long time to prevent the electric pump from overheating and damage.　　The water pump can be used to transport and pressurize clean water without impurities, residence, factory water supply, water supply system, drinking water system and water treatment. In short, there are many uses.Huambo,　　If the submersible slurry pump cannot be installed and operated, the whole machine intrudes into the water to extract water from the underground to the surface. It is commonly used for domestic water, mine rescue, industrial cooling, farmland irrigation, seawater lifting, ship load adjustment, landscape fountains, etc. Submersible pump is generally divided into clean water submersible　　Cavitation of the pump is caused by water evaporation of the pump. The main cause of water evaporation is related to temperature and pressure. Under a certain pressure, when the temperature rises to a certain value, the water begins to vaporize and change from liquid to gas. On the contrary, at a certain temperature, the pressure drops to

　　 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.　　Or the liquid contains fibers. For the medium with solid particles such as paper scraps, the temperature of the medium to be transported is usually not greater than ℃.　　Generally speaking, the above two cases are the case that the slurry pump does not absorb water. The solutions are also introduced. I believe that people can deal with this problem in time. However, if the problem is serious, you must not adjust it at will. At this time, you should find a professionalproduction,　　If the submersible slurry pump cannot be installed and operated, the blank operation point can be supplemented.　　 If the pump is equipped with a vacuum gauge or pressure gauge, close the cock connected with the submersible slurry pump before starting the motor open it after the speed is normal, and then gradually open the outlet sluice valve. If the flow is too large, you can properly turn down the gate valve for adjustment. Otherwise, if the flow is too small,Open the gate valve.　　In order to ensure the demand for water and electricity for production and living, many units, hotels and residential areas in various provinces and cities in China have purchased it and generators. Many enterprises have also purchased generators out of their own pockets in order not to delay production. Driven by this, it and the generator naturally become popular

　　The impeller of the submersible slurry pump may need to be disassembled for maintenance or repair during use. However, when we do not know the pump structure,St. MikelSelf priming non clogging sewage pump, we may make mistakes during disassembly. Let&#;s take a look at the correct disassembly of the impellerTest results,　　 Another possibility is that the gas is sucked in when the pump is in use.　　It can be that there is water leakage in the pipe gasket, pipe or pump body. If the current is greater than usual, we should look for problems from the wear of vulnerable parts.　　To repair the equipment. Submersible slurry pump is a machine used to transport liquid. It can be divided into many types according to different transport media. Then, when transporting some media with special properties, the equipment will be treated with corrosion-resistant and wear-resistant process. Only in this way can the equipment be improvedSt. Mikel,　　In addition to the method, materials shall be selected comprehensively according to the nature of corrosive medium,St. MikelVertical slurry pump, 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.　　After that the secondary and tertiary pumps can be started successively until the final stage pump. After all the series pumps are started, the power used is not matched, so the motor temperature will be too high after long-term overload operation; In addition, frequent startup during use will also lead to fever, so I
