Description

[ background Art ]
Currently, there are relatively limited solutions for irrigation in the market, and most commonly, water supply pump sets on the ground use suction to suck water from a reservoir below the ground for irrigation, or use deep well pumps to supply water under pressure below the ground.

The disadvantages of this solution are mainly manifested in: (1) The scheme has limited application range, because the equipped water pumps are mostly multistage pumps, the self-priming capability is lacking, if the water level at the front end is too low, the effective work cannot be performed, and if the ground water tank is independently equipped, the cost can be obviously increased; (2) Meanwhile, the occupied ground of certain areas needing water supply is relatively tense, and the occupied ground pump rooms can lead to unreasonable post construction arrangement.
Another solution is to use glass fiber reinforced plastic as a cylinder body of the most common dry pump station in the market, assemble the water supply pump inside, dig a pit inside, and place a small submersible pump in the pit for protecting the dry water supply pump set. The disadvantages of this solution are mainly manifested in: (1) Although the water supply pump set can be built in, the actual use state of the water supply pump set is not considered due to the connection between pipelines, impurities possibly enter the water supply pump set when the water is taken in, and the impeller and the motor are damaged; (2) The method adopts an internal pit digging mode, only single-side water seepage is possible to be useful, and once a water seepage point is at other positions, the submersible pump can not effectively prevent water flow, so that the dry pump set is damaged; (3) Because the design of the scheme can lead to unbalanced grouting in the later stage, the whole pump station is in an unbalanced state, and the pump station can be inclined after long time, so that the pump station is damaged; (4) Most pump stations are made of glass fiber reinforced plastic, and once damaged, the pump stations cannot be maintained in the later stage.
