DongjiSubmersible sewage pumpOn the working mechanism of

　　 If the impeller of the pump is damaged after a long time of use, it will also lead to insufficient liquid supply for the pump.　　Ensure that the service time will be extended when it is used. We all know that the submersible slurry pump needs to optimize its structure to meet the requirements of use because the medium it transports is relatively special. The structure has been optimized toDongji,　　At this time, 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 pumpKashmar　　Rate loss, so shaft power = effective power + lost power.　　Moreover, the leaked flammable, explosive and toxic liquid will cause fire, explosion and poisoning,DongjiPipeline pump body, and the consequences will be unimaginable.　　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 addition

　　 After each use of the equipment, high-pressure water should be used to wash the pump and pipes. The washing can be stopped until the water has no impurities.　　Requirements. Then install the pressure regulating film, pressure regulating spring and cover.　　 Precautions for disassembly of submersible slurry pump Before disassembling the filter press, make sure that the liquid in the submersible slurry pump is completely discharged. If the rotor is disassembled drain the lubricating oil in the rotor bearing housing. If the newly added oil is stored, it should continue to be used after maintenance. Do not dump it directlyFocus on Development,　　Submersible pump is a common water lifting equipment for deep wells. During operation, 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,DongjiVertical multistage centrifugal pipeline pump, seawater lifting, ship load adjustment, landscape fountains, etc. Submersible pump is generally divided into clean water submersible　　 The working properties of the two pumps are also different. Because the sewage pump is driven by a motor, it generally has good voltage impact resistance. The submersible pump is of the type of quick opening and quick closing, so it usually uses some small Flow and small pressure.　　 Dust and oil stains on the motor reduce the heat dissipation capacity of the equipment and cause the equipment temperature to rise.

　　Auxiliary mixing or spraying device shall be equipped for easier operation. When the motor is submerged, and the management is easier. The mixing impeller directly contacts the deposition surface and controls the concentration through the diving depth, so the concentration control is more free. Equipment directly submergedEquipment maintenance,　　Head refers to the energy obtained from the pump by the unit weight of liquid output by the pump, so head refers to the effective energy obtained from the liquid output by the pump in unit time - that is,DongjiCirculating hot water pipeline pump, the effective power of the pump: the equation is PE= ρ GQH (W)= γ QH (W)　　Submersible sewage pumps are divided into xwq (cutting submersible sewage pump), wq/qw (non clogging sewage pump), jywq (automatic mixing sewage pump) and other series according to their s. One of the most commonly used is wq/qw (non clogging sewage pump), which adopts runner type impeller and generally has the features of energy saving, anti winding non clogging and automatic　　Rate loss, so shaft power = effective power + lost power.Dongji,　　In fact, when the submersible slurry pump is blocked during use, but also cause serious damage to the equipment itself, so it is also a reminder that we are using it too　　Yes, summer is the peak sales season. In addition to agricultural applications, industrial pumps have also increased in recent years.　　 It may be that the motor power of the water pump is too large, the working current is too large, and the heat generation is too large, resulting in the high temperature of the vacuum pump.
