YavneVertical slurry pumpReasons for the problem of sense of value

　　 Dust and oil stains on the motor reduce the heat dissipation capacity of the equipment and cause the equipment temperature to rise.　　The submersible slurry pump is a kind of submersible pump which is connected with the motor and works underwater at the same time. In addition, compared with horizontal slurry pump and vertical slurry pump, submersible slurry pump has the great advantage of flexibility and convenience, and is more suitable for various working conditions. The important technical points of submersible slurry pump are its motor andYavne,　　The working principle of the self-priming pump is to fill the pump casing with water (or there is water in the pump casing itself) before the pump is started. After startup, the impeller rotates at a high speed to make the water in the impeller channel flow to the volute. At this time, a vacuum is formed at the inlet to open the water inlet check valve. The air in the suction pipe enters the pump and　　Therefore, the correct selection of shaft seal can ensure the safe and stable operation of slurry pump.Ananindeua,YavneHorizontal slurry pump,　　The packing seal, auxiliary impeller seal and mechanical seal are mainly used. Among them, the packing seal needs small leakage and is not suitable for transporting toxic, corrosive and precious liquids; The sealing of the auxiliary impeller relies on the reverse pressure of the two sealing impellers during rotation to prevent the leakage of the medium, and can also play a role in　　Where ρ—— Density of transmission medium liquid (kg/m; γ—— Gravity of medium liquid (n/m; H -- pump lift (m); Q - water pump flow (m/s); G - gravitational acceleration (m/s.　　The difference between the shaft power P and the effective power PE is the power loss in the pump, which is measured by the pump efficiency. The pump efficiency is the ratio of the effective power and the shaft power which is measured by η Indicates.　　 selection of pump head: generally, the pump head shall be determined by enlarging the margin of % - %.

　　The fruit is also bad; When the axial flow pump is used, its water output is relatively large, but the head is not too high so the effect of using the submersible slurry pump in many plain areas is also relatively good; The water output and head of the mixed flow pump are actually derived from one　　Whether there is any fault.　　Third,YavneHorizontal non clogging sewage pump, the whole industrial and mining system operates stably,　　Different installation requirements: the vertical slurry pump needs to be fixed, while the submersible slurry pump does not need to be fixed. It can directly invade into the liquid for operation.　　Start the priming pump. Moreover, due to the structural limitations of the submersible slurry pump, the motor needs to be placed on the water surface for use during operation, and then the pump needs to be placed in the water for use. Therefore, you can refer to the following reasons.

　　 There may also be mechanical failure of the pump, such as serious damage to the bearing of the pump,YavneWQ submersible pump parameters, 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 waterMeticulous workmanship,　　 The standby submersible slurry pump shall roll the shaft / turn every week to make the bearing uniformly accept the static load and external oscillation. The building structure in the water pump room shall be reconstructed. Sound absorbing and isolating plates shall be installed around the wall and on the top of the machine room and fixed with light steel keel; The connecting holes between the machine room and other rooms are tightly blocked,　　 the water treatment equipment shall be selected according to times of the relatively large water consumption per hour.　　So it has a process of water diversion and exhaust. There are usually two ways to inject water into equipment. One is to directly inject water into the pump chamber, and the other is to pump out the gas in the pump to establish a certain vacuum and introduce the water source.Yavne　　Friction resistance due to bearing and packing; Friction between impeller and water during rotation; The vortex of water flow in the pump, gap reflux, 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　　Analysis of installation problems of slurry pump For bearings lubricated with thin oil, oil shall be added according to the oil level line of the oil standard before start-up. Add (HL hydraulic oil in winter and (hl hydraulic oil in summer. The bearing lubricating oil of the slurry pump shall be replaced once after continuous operation ( hours.　　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.
