selection of pump head: generally, the pump head shall be determined by enlarging the margin of % - %.　　The supply of shaft seal water must be ensured. It is strictly prohibited to operate without water, otherwise the mechanical seal will be burned.Francois,　　The fire control cabinet adopts centralized management and one key operation. The startup procedure is simple and convenient. It can control multiple fire pumps at the same time, greatly providing work efficiency.　　At the same time, the supporting pipelines in the pump room shall be provided with vibration isolation elasticity.Troyan　　Circumference. In the application of slurry pump, we must pay attention to reasonable design, correct calculation and appropriate type selection, which are very important. In addition to the main wheel, a set of stirring impeller is added at the bottom of the product, which can spray the precipitated slag into a mixture of water and solid particles　　This phenomenon shows that the failure of the pump is not only a material problem, but also reminds the pump designers and producers that in addition to good working conditions, the pump should also have good corrosion resistance, high reliability and long service life. The pump shall be designed in addition to the conventional design method of fluid mechanics　　Through the introduction we learned that the submersible slurry pump can be used to transport slurry when it is used at ordinary times. The relationship between its special structure is very close, but in fact, it also needs to be used in a correct way when it is used at ordinary times. Only in this way can

　　It needs to be replaced in case of damage, insufficient spring pressure, breakage, etc.　　 Pipeline booster pump: in fact, any pump that can pressurize the liquid delivered in the pipeline can be called a pipeline booster pump. Not limited to one type of pump, such as centrifugal pump, pipeline　　In addition to the main impeller inside the equipment, a set of impeller for mixing will be added at the bottom of the equipment, so that some mortar slowly settled inside the equipment can be mixed with water to become a flowing medium, so that the equipment can be used without itsQuality inspection report,　　Work, no noise and vibration, and the site is cleaner.　　 It may be that the motor power of the water pump is too large,FrancoisWear resistant slurry pump, the working current is too large, and the heat generation is too large,FrancoisSmall deep well pump, resulting in the high temperature of the vacuum pump.　　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,FrancoisBooster pipeline pump, many people believe that

　　 First remove the pump from the engine.Inspection items,　　The Tao part also consumes part of it.　　 After one year of use, check the corrosion of the pump, remove the rust and paint. If the submersible pump is not used for a long time, it should be carefully checked and put dry.　　Carbon, building materials, chemical industry and other industrial industries are mainly used to transport abrasive pastes containing solid particles.Francois,　　With water, it will not only require frequent maintenance during operation, but also leak a large amount of transmitted liquid.　　Water flow into the bearing damages the bearing.
