A High Efficiency Pumping and Irrigation Automatic Converter

Abstract

The invention discloses an automatic efficient pumping and recharging convertor which comprises a pipeline, wherein two ends of the pipeline retract radially; at least one pair of open pores are formed in the pipe wall; a rod object is assembled in the pipeline; the rod object is fixedly connected with a cylinder; the cylinder is in sliding fit with the inner wall; the height of the cylinder is larger than the diameter of each horizontal open pore; the lower end of the rod object is fixedly connected with a cylindrical piston; and the diameter of the cylindrical piston is larger than the inner diameter of a lower opening of the pipeline. Head pressure in a pumping and irrigation process is used for pushing the cylindrical piston to move, and bi-directional purposes of pumping and recharging can be realized by one pipeline. The head loss is small, the efficiency is high, the defect that a pump pipe loosens due to the fact that two pipes collide during recharging or re-spreading is avoided, a small diameter well can meet the recharging or pump lifting requirement, the well completion cost is reduced, attachments on the filter pipe wall can be effectively washed away under the condition that the stable state of the pump pipe is guaranteed, recharge well blocking is reduced, and the service life of a recharge well is prolonged. The automatic efficient pumping and recharging convertor can be widely applied to submerged pump connection, rain flood groundwater recharge, ground source heat pump water cyclic utilization, well repair, groundwater recharge and water supply diversion.

Description

technical field [0001] The invention relates to a pumping and irrigation device, in particular to a pumping and irrigation converter. Background technique [0002] The water source heat pump centralized central air-conditioning system is an energy-saving and environmentally friendly green air-conditioning system that has been promoted in my country in recent years. In order to prevent the waste of groundwater, both the pumping pipe and the refilling water pipe are installed in the same well, resulting in a waste of materials; since there are two sets of pipes in the well pipe, in order to ensure the water supply, the well pipe with a larger inner diameter must be used. Due to the complicated process of running the pipe, the cost of drilling and running the pipe is increased, resulting in an increase in cost. Not only is the physical labor of lifting the pipe down is heavy, but the safety of the well is not guaranteed. Contents of the invention [0003] The invention provi...

In order to prevent the waste of groundwater, both the pumping pipe and the refilling water pipe are installed in the same well, resulting in a waste of materials; since there are two sets of pipes in the well pipe, in order to ensure the water supply, the well pipe with a larger inner diameter must be used. Due to the complicated process of running the pipe, the cost of drilling and running the pipe is increased, resulting in an increase in cost. Not only is the physical labor of lifting the pipe down the pipe is heavy, but the safety of the water well is not guaranteed.
