it can pump liquid from low to high or far away to serve production.　　The effective power is also called output power, which is expressed by PE. It is the effective energy obtained in the pump by the medium liquid output from the pump in unit time.San Francisco El Alto,　　In order to make it convenient for you to know this excellent submersible sewage pump, we will give you a simple explanation with the QW submersible non clogging sewage pump, which is often used. Please look at the following content.　　Under the action of auxiliary devices, it can transport the slurry, and because the sealing device itself is special, it can also ensure the internal and external balance of the submersible slurry pump during transportation, so that the pressure at both ends of the equipment can be balanced during normal useMars,San Francisco El AltoWQ submersible sewage pump,　　 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.　　 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, 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　　After that, before starting again, check whether the impeller rolling is normal and whether the bearing assembly compression bolts are tightened, and then start the pump.

　　 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.　　Motor heating: cause: A. whether it is overloaded; b. Pump motor failure; c. Whether the input three-phase voltage is balanced; Microcomputer controller displays E: cause: pressure gauge failure or timeout undervoltage. In this state press the key to eliminate the alarm.　　Rate loss, so shaft power = effective power + lost power.A complete range of products,　　 It is also possible that the fan blades of the pump are few and the air volume is insufficient, resulting in poor heat dissipation effect.　　The structure of the submersible slurry pump will be more intuitive. First, the equipment will use centrifugal force to drive the liquid from the impeller to the outer edge and obtain energy, and then leave the edge of the impeller at a higher speed　　 First, screw down the bolts on the side bearing pressure cap, stuffing box body and bearing body; Then screw off the round nut on the shaft, and successively install the bearing inner race, bearing gland and retaining sleeve

　　The whole packing body, including the packing gland, packing ring and packing, needs to be disassembled; Submersible slurry pump Disassemble the o-seal ring, shaft sleeve, balance disc and key on the shaft in turn, and then the discharge section includes the last stage guide vaneConvenient and efficient,　　Although the shaft seal occupies a small position in the pump, the normal operation of the pump is closely related to the shaft seal.　　 use a volt megger to check the insulation resistance,San Francisco El AltoVortex pump and pipeline pump, which should not be less than . megohm. If it is lower than this value, open the drain hole and vent hole for drying or drying.　　 There may also be mechanical failure of the pump, such as serious damage to the bearing of the pump, so that the bore will be 'swept' when the stator and rotor rub against each other or the impeller will be stuck due to impurities such as water and grass when the pump pumps waterSan Francisco El Alto,　　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　　With the continuous development of slurry pump technology, and of course it can be more than. For example, the maximum design depth of our company&#;s underwater slurry pump can reach m, but such underwater depth is not the best operating depth of this kind of pump, so it will lead to the unreliability of the operation of the vertical slurry pump from time to time.　　What is the solution to this situation?
