Description
Technical Field

Background
The vertical submersible electric pump has the advantages of compact structure, simplicity and rapidness in installation, simple civil construction of pump stations, small influence on the surrounding environment during operation and the like, so that more and more pump stations adopt a scheme for installing the submersible electric pump. When the vertical submerged electric pump unit loses power and enters a braking working condition, water flow in the pump body rapidly flows back to the water inlet tank under the action of gravity to form vacuum in the pump body, so that the gravity of the rotor of the unit is smaller than lifting force, a lifting phenomenon is generated, and the unit is greatly damaged.
At present, in order to avoid the damage of a lifting machine to a unit in engineering, a rigid supporting rod is mainly arranged between a vertical submerged pump and a sealing cover plate of the vertical submerged pump. The conical lower end of the rigid supporting rod is tightly pressed on the upper part of the pump body, the upper end of the rigid supporting rod is fixedly connected with the sealing cover plate of the submerged pump through bolts, and the sealing cover plate is fixed on a concrete foundation through an embedded part. At this time, the lift-preventing device can prevent the submerged electric pump from lifting by generating a downward force on the pump body through the sealing cover plate and the rigid supporting rod. The lifting-preventing device has a simple structure, but the rigid support rod can cause turbulence of water flow in the flow channel, so that the unit vibrates, and great potential safety hazard is brought to stable operation of the unit; in addition, if the submersible electric pump sealing cover plate is far away from the pump body, the rigidity of the rigid support rod needs to be greatly improved to meet the functional requirements, and the engineering investment is increased.
Therefore, it is highly desirable to find a quick-dismantling type vertical submerged pump anti-lifting machine base, so that a pump body can be stably fixed on the base, and the damage to the pump body caused by lifting of the submerged pump is effectively prevented, so that long-term safe and stable operation of a unit is ensured.
