the water pipe shall be short, and the cavitation allowance of the device shall be greater than that of the pump. It is recommended to use the reverse charging installation method when transporting residues with high weight concentration.　　 The fixing method of the impeller is changed from screw thread to key clamp to prevent the impeller from falling off and causing damage!Shangri la town,　　 the insulation resistance between the shaking cable and the submersible slurry pump shall not be less than megohm.　　Superior, convenient installation and high cost performance. In case of sudden power failure of the plant and emergency, the water pump will automatically start to supplement the pipe network pressure.Kujang-up,　　The solution to the excessive temperature of the water pump: when selecting the motor,Shangri la townQJ submersible pump, 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 pump　　It needs to be replaced in case of damage, swelling and deformation insufficient spring pressure,Shangri la townVertical heavy-duty slurry pump, breakage, etc.　　 First remove the pump from the engine.

　　How to avoid this situation when the equipment is in use.　　 The pump fails to supply water or the flow is insufficient. The pump fails to supply water or the flow is insufficient. It is likely that the suction pipe has water leakage or the bottom valve has air leakage, but there are several possible reasons: the water inlet is blocked; The bottom valve is not deep enough underwater; The running speed of the water pump is not enough; leaf　　First, the reason for the motor body: the wrong connection will make the temperature rise rapidly when the equipment is used; In addition, there may be some phase to phase short circuits between stator windings, so when the situation is relatively minor, the motor is only in local placesoriginal,　　If the pressure in the local area is equal to or lower than the vaporization pressure corresponding to the water temperature in the flow process, the water will vaporize there and form many small bubbles mixed by steam and gas. The cavitation phenomenon is due to the bubble action when these small bubbles flow from the low-pressure area to the high-pressure area in the water pump,　　A large amount of lubricating oil is stored.　　 If the head of the submersible slurry pump is too low or the head is higher than the practical condition, 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.

　　The disc friction loss of the slurry pump impeller will decrease with the decrease of the impeller diameter, so that the pump efficiency of most low specific speed pumps will improve slightly after the impeller is cut. After cutting, and the degree of blade overlap will decrease with the addition of specific speedEncyclopedic knowledge,　　 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.　　If this coating is removed over time in subsequent work, the owner of the stainless steel deep well pump can use another coating to resist corrosion and hot water.　　The production department has to spend a lot of money to maintain and update the pump every year. The pumps made of cast iron, bronze, rubber lining, stainless steel, titanium alloy and other materials used in China&#;s mining, chemical and water conservancy projects on the Yellow River are prone to wear, short service life and many faultsShangri la town　　If the water leakage is serious, the broken pipe shall be dismantled and replaced. Lower the lift and press the nozzle of the water pump into the water for .m.　　Potential energy, pumping water up high. However, once the pump can not absorb water, the equipment is shaped like a decoration,Shangri la townSingle stage slurry pump, so what is the reason for this situation? How to solve it?　　Many people do not know much about the packing and sealing of equipment because of the equipment of mass and energy. Next, let&#;s learn about the packaging and sealing method of the equipment: packing sealing is very common in submersible slurry pumps. This method has good sealing performance, is easy to use, and effectively reduces the wear of the host and anti vibration kinetic energy
