Be sure to choose a pump that is more suitable for use.　　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, the atmospheric pressure will move the water pressure to pump water. In fact, from a al point of view, it is to convert electrical or chemical energy into gravitySt. patten,　　 daily, quarterly and annual inspection, maintenance and use plans shall be prepared for deep well pumps.　　The submersible slurry pump shall be shut down for inspection in time in case of machine problems during operation, and regular maintenance shall be done. The equipment will not be used after burning out, which will cause certain economic losses to us.Karvina,　　The submersible slurry pump may be blocked when it is used at ordinary times. In particular, some equipment is frequently used at ordinary times, but the maintenance work is not done well when it is used, so it will be blocked after being used for a period of time　　Potential energy, pumping water up high. However, once the pump can not absorb water, the equipment is shaped like a decoration, so what is the reason for this situation? How to solve it?　　There will be no insufficient liquid supply or other problems.

　　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.　　 Frequent opening and closing: the frequent starting of submersible sewage pump will affect its service life. Backflow will occur when stopped. If it is opened immediately, the motor load will start, resulting in excessive starting current and winding combustion.　　 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, 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 bodyproduction costs,　　Friction resistance due to bearing and packing; Friction between impeller and water during rotation; The vortex of water flow in the 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　　 Next, it is necessary to check the water seal. If the water seal is bakelite and the wear is not too serious, you can place abrasive cloth on the glass or dry wood,St. pattenWQ submersible pump parameters, and then grind the water seal of Boshan submersible slurry pump flat or turn it over for use. However, if the thrust rubber water seal is used, when　　Submersible slurry pumps are mainly used in mining,St. pattenVertical multistage centrifugal pipeline pump, metallurgy, environmental protection, electric power and other industries to transport corrosive solid particle slurry. For example, in the field of chemical industry,St. pattenHorizontal non clogging sewage pump, corrosive mixed pastes of chemical crystals are transported. Electric ash removal, coal washing plant slurry transportation, etc. Submersible slurry pump blade

　　 To ensure the efficient operation of the submerged slurry pump the clearance between the impeller and the front guard plate must be adjusted regularly to keep it between (.-mm). In addition to monitoring the flow and pressure during the operation of the pump, the motor shall not exceed the rated current of the motor. Monitor oil seal and bearing at any timeTest method,　　 Cutting blades can be selected to cut some large block solid substances into pieces during use, so that blockage can be avoided during reuse.　　Correct the bent main shaft and adjust the position of the motor and the water pump to make them parallel.　　After understanding the working principle of the submersible slurry pump, we will also know that those parts are prone to wear during normal use. In this way,　　 If the head of the submersible slurry pump is too low or the head is higher than the practical condition so as to improve the integrity of the equipment andSt. patten, the flow will be large and the current will rise. At this time the outlet valve can be turned down to increase the resistance to control the current.　　 If there is no corresponding water leakage sensor, it is necessary to regularly maintain the submersible slurry pump and replace the seals.　　 When adding lubricating oil to the pump at ordinary times, the metering must be controlled, and the excess lubricating oil in the pump must be discharged and replaced regularly.
