A vent pipe is installed at the bottom of the pump, so that when the pump is buried underground, water will be injected into the bottom of the slurry pump through the vent pipe, so that the slurry pump can be started normally. The advantage of this approach is that even if　　Normal operation. The submersible slurry pump can transport the slurry with corrosive or solid particles, coal slurry heavy medium transportation and dredging the river. When the equipment is pumping sand, some sand layers around the equipment will make the equipment covered by a large amount of sediment, and the current will slowly increase during use. Well, we should chooseRao Zhan,　　 With protection . cf fire control cabinet integrates many electrical components which can form a three-dimensional protection for the fire pump, including voltage overvoltage and undervoltage protection, current overcurrent and undercurrent protection, phase loss protection, overheating protection etc. this　　Carbon, building materials, chemical industry and other industrial industries are mainly used to transport abrasive pastes containing solid particles.Shakyarabadin,　　; In practical application, while the submersible slurry pump can be used directly without immersion,Rao ZhanRubber lining submerged slurry pump, which is convenient and flexible.　　Potential energy, pumping water up high. However, once the pump can not absorb water, the equipment is shaped like a decoration,Rao ZhanSmall deep well pump, so what is the reason for this situation? How to solve it?　　The mixing impeller and other main flow passage parts are made of high wear-resistant materials,Rao ZhanVertical centrifugal slurry pump, which are wear-resistant, corrosion-resistant, non clogging and have strong sewage discharge capacity, and can effectively pass through large solid particles. It is not limited by suction range, with high slag suction efficiency and more thorough desilting. No auxiliary vacuum pump is required and the investment is lower. nothing

　　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.　　 The casing ground wire of the electric pump shall be connected in strict accordance with relevant regulations. When the electric pump is running, it is strictly prohibited to work or move in the water of nearby devices or people, in case of accidents caused by the power distribution of the electric pump.　　It is an auxiliary means for some on-site monitoring.Customer first,　　Wheel, mixing impeller and other main flow passage parts are made of high wear-resistant raw materials, which are wear-resistant, corrosion-resistant, non clogging, and have strong sewage discharge capacity and can effectively pass through large solid particles. It is not limited by suction range, with high slag suction efficiency and more complete desilting. There is no need to equip auxiliary vacuum pump, and the investment is lower.　　So it is called: submersible slurry pump.　　The utility and durability of the utility model, so the polymer composite materials are generally used in production.

　　 drainage and water injection with vacuum equipment: the self exhaust of centrifugal pump is the same as the negative pressure exhaust of vacuum pump, so the water ring vacuum pump is used for exhaust to achieve the of water inlet.Work courses,　　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.　　Operation management of screw pump Nemo pump (single screw pump) is a positive displacement pump, which is widely used in sewage plant to transport sludge and chemicals containing solid particles.　　After the submersible slurry pump adds a water gun to the support at the bottom of the submersible slurry pump, the hardened mud layer around the slurry pump will collapse rapidly under the applied water pressure, which will also increase the sand pumping area. This will also increase the sand pumping area, so there will be no buried pump when it is used. However,Rao Zhan,　　Normal operation. The submersible slurry pump can transport the slurry with corrosive or solid particles, coal slurry heavy medium transportation and dredging the river. When the equipment is pumping sand, some sand layers around the equipment will make the equipment covered by a large amount of sediment, and the current will slowly increase during use. Well, we should choose　　If there are sundries blocked, the pump will not be filled with water. When this happens again, and check the impeller. In case of damage or aging, it needs to be replaced in time,　　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.
