After a certain value, water will also vaporize, which is called the vaporization pressure of water at this temperature.　　 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.Tonara,　　 When the slurry pump operates, it rotates at a high speed, and the components of the slurry pump have a heavy weight. Therefore once it reverses, the force will directly push the impeller to the outside, and the impeller collides with the sheath and guard plate. If the speed is high, the force ratio is low　　 Before starting the submersible slurry pump, the rotor of the rotating pump shall be smooth and even, and water shall be injected into the pump to ensure that the pump is full of water without air.Bagland Province,　　 if the removed gasket is seriously damaged, a new gasket shall be replaced. The removed parts shall be cleaned with kerosene before assembly.　　Do not exceed the rated current.　　If there are sundries blocked,TonaraDeep well pump, the pump will not be filled with water. When this happens again, technicians need to properly adjust the liquid level in the pump sump to a proper height, it needs to be replaced in time,

　　 strip the outer layer of the cable to expose the copper wire for to mm, gradually thin the rubber near the wire core,TonaraRubber lining submerged slurry pump, grind it to the oxide layer on the wire core, wipe the wire core with alcohol (or hydrochloric acid), wrap the insulation layer and sheath layer, and dry it naturally.　　Unsuitable pump head is selected.　　The water pump can be used to transport and pressurize clean water without impurities, such as apartment, residence, villa water supply,TonaraSplit vertical pipeline pump, factory water supply, water supply system, drinking water system and water treatment. In short, there are many uses.Finance Department,　　Limited. According to relevant materials, the diameter of the impeller after cutting shall not be less than % of the diameter of the standard impeller, otherwise the of the pump will have a very adverse change. After the impeller of the slurry pump is cut, the flow area in the pump body increases, grind it to the oxide layer on the wire core gradually thin the rubber near the wire core, wipe the wire core with alcohol (or hydrochloric acid), wrap the insulation layer and sheath layer, and dry it naturally.　　Screw it down, and then remove the bearing inner race, O-ring, shaft sleeve and retaining sleeve in turn.

　　 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.Customer first,　　The above is the correct sequence of impeller disassembly of submersible slurry pump. Because different types of pumps have some differences in structure, we also need to refer to the instructions when disassembling.　　The main shaft of the water pump is bent or the main shaft of the water pump and the motor is not concentric or parallel.　　 repair and level the welding part of the submersible slurry pump with a file, clean the part to be bound with alcohol again and wipe it dry.Tonara, so that the pump efficiency of most low specific speed pumps will improve slightly after the impeller is cut. After cutting, keep the blades overlapped to a certain extent and the degree of blade overlap will decrease with the addition of specific speed　　 When stopping the operation of the submersible slurry pump, close the cock of the vacuum gauge and pressure gauge and the gate valve on the water outlet pipeline, and After that, cut off the power supply of the motor. If the temperature of the environment is low, open the square plug at the lower part of the pump body to remove the remaining water to avoid frost cracking. During operation, the maximum temperature of the bearing shall not exceed ℃, and the quantity of calcium base grease used for lubricating oil bearing shall be the same as that of the bearing body　　 The submersible slurry pump needs to be inspected after reassembly. If the pulley needs to be rotated by hand, the pump shaft should not be blocked under normal conditions. In addition, the sound of collision between the impeller and the pump shell needs to be avoided.
