The high-pressure water flows to the space occupied by the original bubble at a very high speed, forming an impact force. The metal surface of the pump was fatigued and damaged by these impacts. Cavitation is caused by air bubble rupture and material stamping due to the difference in air temperature and pressure　　 The pump body (can not) bear the pressure from the outlet pipeline system. The standby pump in the warehouse should rotate (/ times a week to make the shaft bear the load and external vibration evenly. The belt CR drive is that the motor is on the (right) side of the pump from the inlet of the pump.Longueuil ,　　The equipment of this series of sewage pumps can be fixed or mobile. When the fixed active equipment is selected, the chain cable shall be separately threaded into (against the pump outlet, and its connection shall be parallel to the pump outlet) two eyebolts or lifting plates to lift the electric pump up and down. Evenly and slowly along the guide rail　　Let the medium containing some solid particles generate a certain flow rate, so that the equipment can drive the solid to flow when it is in use,Longueuil Vortex pump and pipeline pump, so that the slurry can be transported. In terms of the principle of the submersible slurry pump, it is actually quite simpleSokone,　　Work, no noise and vibration, and the site is cleaner.　　 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.　　The motor is scrapped. Moreover, because the length of the long shaft is generally fixed, the installation and use of the pump is troublesome, and the application occasions are subject to many restrictions.

　　Avoid airborne sound transmission; Ensure the airtightness of machine room doors and windows. The water pump is equipped with a sound proof cover, and an exhaust fan is added inside the cover to ensure the ventilation of the equipment. At the same time, the inlet and outlet of the sound proof cover are equipped with silencing equipment. A vibration isolation platform is installed at the bottom of the water pump for foundation vibration reduction to isolate the vibration generated during the operation of the water pump　　In fact, stainless steel is not only advocated in the medical industry, but also widely used in the water pump industry. The stainless steel submersible pump of denang pump is one of them.　　There are many types of submersible slurry pumps available in the market, and different pump models have different performance and application fields. Therefore, although the pump has a wide range of applications, if its model is not correctly and reasonably selected, its application effect will be greatdiscount, the smaller the allowable cutting amount of impeller diameter. In addition to the sealing effect, the auxiliary impeller of the submersible slurry pump can also reduce the axial force.　　Troubleshooting: first increase the water pressure then inject water into the pump body, and then start the pump. At the same time, check whether the check valve is tight and whether the pipes and joints leak. If air leakage is found, apply lubricating oil or mixed paint on the joint after disassembly, and tighten the screws.　　Friction resistance due to bearing and packing; Friction between impeller and water during rotation; The vortex of water flow in the pump,Longueuil Vertical slurry pump, gap reflux, inlet and outlet impact and other reasons. A part of the power must be consumed, so it is impossible for the water pump to completely change the power input by the power machine into effective power, in which the constant active power

　　The input quantity is related to many factors such as the rotating speed of the submersible slurry pump, the bearing standard, the continuous working time, the number of stops and starts of the pump, the surrounding environment and the working temperature. Therefore it is necessary to gradually accumulate the experience and add smooth oil in a reasonable and timely manner.project,　　When the water pump is driven by electricity or diesel engine, its impeller (like an electric fan) rotates wildly, thus forming a vacuum in the impeller. In this way, from a al point of view, it is to convert electrical or chemical energy into gravity　　Steam will produce air bags, which are harmful to water and seriously damage the vacuum suction. In order to immediately empty the pipe, rather than an immediate vertical rise, generally exceeding ., which should be the height of the top water pipe along the pump inlet　　 Then reinstall the equipment on the engine and install the rubber hose.Longueuil ,　　 Impeller protection in order to ensure the operation of the submersible slurry pump, it is necessary to timely adjust the clearance between the impeller and the front guard plate. When adjusting the impeller clearance, first stop the pump, loosen the bolts pressing the bearing box, loosen the adjusting nuts, make the bearing components move forward and roll the shaft by hand to press the　　The direction of the differential pressure force is opposite
