Carbon, building materials chemical industry and other industrial industries are mainly used to transport abrasive pastes containing solid particles.　　 First, screw down the bolts on the side bearing pressure cap, and then remove the nuts used for the connection between the three parts: discharge section, stuffing box body and bearing body; Then screw off the round nut on the shaft,MathisCorrosive pipeline pump, and successively install the bearing inner race,MathisSewage pump diving, bearing gland and retaining sleeveMathis,　　The treatment method is as follows: first, check the circuit voltage to reduce the speed of the water pump.　　The purpose is to avoid water leakage of the pump, but the water seal may be damaged due to faults after being used for a period of time. Let&#;s learn how to replace the water seal.Pirot,　　In addition, the sundries inside the pump body and impeller shall be cleaned. Then calibrate the pump shaft and motor shaft of the slurry pump to make them on the same horizontal line.　　 Move the sand pumping site frequently. When the pump pumps sand at a fixed position and drops to a certain height, lift the submersible slurry pump and move it to the adjacent position of the previous sand pumping place to continue pumping sand, so as to move the sand pumping place back and forth for sand pumping, so that the sand pumping area in this area forms a honeycomb,　　 If the hot water within ℃ is recommended, the hot water pump must be used, and the external tap water shall be connected for cooling during operation, otherwise the motor will not be burned due to too high medium temperature.

　　When the submersible slurry pump works, the pump needs to be placed on land, and the pump needs to be started. Due to special structural requirements, when the slurry pump motor is submerged in the water, the slurry pump and submerged slurry circulating pump need to be placed above the water surface, so they need to be fixed, otherwise the motor will fall into the water　　At this time, it is necessary to use the fire control cabinet. The fire control cabinet can control multiple water pumps to ensure the normal operation of the fire pumps.　　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 gravitynew product,　　There will be no insufficient liquid supply or other problems.　　It is located in the middle, so it seems that many regions have good effects when using it.　　 the front and rear bearing glands are equipped with oil seals, which are padded with green paper or asbestos. There is a gap of .- mm between the rear gland and the bearing.

　　What stands out is the sealing of the container. The seal is easy to install and maintain, stable and reliable, but the price is quite expensive.where　　Different process requirements: the motor used in the vertical slurry pump is an ordinary vertical motor, which has no waterproof . The motor of the submersible slurry pump and the pump shaft are coaxial. The motor shall be waterproof and sealed. The motor and the pump body can invade underwater at the same time.　　 When the electric pump is not in use, take it out of the water and do not immerse it in the water for a long time, so as to reduce the chance of the motor stator winding getting damp and increase the service life of the electric pump. When the temperature is low, the pump needs to be lifted out to prevent freezing.　　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, and is more suitable for various working conditions. The important technical points of submersible slurry pump are its motor andMathis,　　Cavitation of the pump is caused by water evaporation of the pump. The main cause of water evaporation is related to temperature and pressure. Under a certain pressure, when the temperature rises to a certain value, at a certain temperature, the pressure drops to　　 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.　　Ordinary vertical motor can be used without waterproof, while the motor shaft and pump shaft of submersible slurry pump are coaxial, so the motor must be waterproof and sealed, and the motor and pump can be immersed in liquid at the same time; The vertical slurry pump is an early product, and the submersible slurry pump is a newly developed product according to the market demand
