Description

The method for installing the submersible (sewage) pump in the prior art in the industry is as follows: the expansion bolts or other fasteners are adopted, the coupling base is fixedly arranged at the bottom of the water tank, the upper end of the coupling base is provided with an inclined plane, the water pump and the coupling plate are fixedly connected into a whole, then the coupling plate descends along one or two circular guide rods, and when the coupling plate reaches the lowest point, the coupling plate is hung on the inclined plane at the upper end of the coupling base, and the coupling surface is tightly pressed by the gravity of the water pump, so that sealing is realized.

The prior art CN211692966U discloses an automatic coupling installation base structure with shock attenuation effect for pump station, the on-line screen storage device comprises a base, the water pump is installed to one side on the base, the pipeline under pressure is installed to the opposite side on the base, be provided with the guide rail that vertically runs through on the base, the lower bottom surface of base is provided with the mount pad, the mount pad divide into pedestal one, pedestal two and pedestal three, the pedestal three side terminal surface is connected with the guide rail lower part side terminal surface that runs through the base, the shock attenuation fixed block is installed to the lower bottom surface of mount pad and guide rail, the shock attenuation fixed block passes through the fixed locking of bolt and lower bottom surface fixed object, the pedestal three passes through dead lever fixed connection with the guide rail lower part that runs through the base, the dead lever of pedestal three inside passes through screw and lower bottom surface fixed object fixed locking. Through mount pad and shock attenuation fixed block and bolt, improve greatly and fixed article firmly fixed locking state of bottom surface down, improved the absorbing effect greatly.

In practice, it is found that the existing coupling installation base structure has more problems, personnel enter a pump pit of a closed space to install or overhaul a water pump base, great potential safety hazards exist, a large amount of flammable and explosive biogas and toxic gas exist in the tank, and the gas emitted from the sludge cannot be eradicated even if ventilation is performed. Therefore, accidents such as casualties, property loss and the like of the maintenance personnel are reported in a tired way.

The suspension coupling installation mode has the following fatal defects that the future maintenance, installation, updating and substitution are not considered at all in the foundation design and the newly-built construction installation, and negative effects and losses are brought to users.

(1) The coupling base must be installed in the empty pool, and the installation with water cannot be realized. The installation method is only suitable for new engineering application, but when the installation method is used in reconstruction and expansion engineering, the pool needs to be emptied and the bottom of the pool needs to be cleaned, so that the normal operation of the established project is affected, and even the production is stopped. Particularly in sewage treatment engineering, the waste water treatment device can only exceed discharge when in production stopping, so that serious environmental accidents are caused, and bad influence is caused on sewage plants and governments. In addition, many front-end gates are found to be lost in practice over time, and these gates are operated underwater and at the forefront of the entire system, with no service conditions at all. Once the front-end gate is damaged, the pump pit cannot be emptied at all, the coupling seat cannot be overhauled after being damaged, the newly-added water pump also does not have installation conditions, so that project construction cannot normally pass water, and inspection and acceptance cannot be passed.

(2) The coupling plate is limited left and right by means of the guide rod, so that the gap is large in order to ensure the upper and lower smoothness, and the phenomenon of left and right deviation frequently occurs during final coupling. The left-right deviation causes the overcurrent area to be reduced and the local resistance to be increased to be lost, thereby increasing the operation energy consumption. Particularly, when the water pump is applied to a small-caliber water pump, the influence is great.

(3) The coupling plate is hung on the inclined plane of coupling base upper end, relies on the gravity of water pump to compress tightly the coupling face, and when the water pump bore increases or the outlet pressure is great, the rivers reaction force of pump during operation will promote the lower extreme slotting of coupling plate, keep away from the coupling base formation can't seal. These fatal defects can lead to water leakage of the coupling surface, so that flow loss, energy utilization rate reduction and energy consumption increase are caused; and the working state can cause the vibration of the pump and the coupling base to be increased, so that the damage of the pump and the coupling base is accelerated.

The above problems are all the problems that the technicians in the industry have not solved.
