Abstract
The utility model relates to a novel self-sucking pump which comprises a pump body and a piston. The utility model is characterized in that an upper sealing cover is arranged on the upper end of the pump body, and a lower sealing cover is arranged on the lower end of the pump body; one side of the pump body is respectively communicated with the upper and the lower parts of one side of a piston cavity of the pump body by an upper and a lower water inlet pipes of a three-way pipe, and the corresponding other side of the pump body is respectively communicated with the upper and the lower parts of the other side of piston cavity of the pump body by an upper and a lower water outlet pipes of the three-way pipe; the piston is arranged in the piston cavity of the pump body, and a connecting rod passes through the upper sealing cover, and a seal fixed on the upper sealing cover is connected with the piston by a rocking handle. The self-sucking pump can pump and discharge water at any depth which is lower than a water outlet, and particularly can directly pump out water below 14 meters of the water outlet. The utility model has the advantages of reasonable design, simple structure and convenient use.
Description
Technical field
The utility model relates to a kind of water plug, exactly is a kind of self-priming pump.
Technical background
Suction pump is a kind of water plug commonly used, and the self-priming pump that generally is used to draw water at present can not directly be extracted out being lower than the water of water outlet below 14 meters mostly, and using has limitation, very inconvenient.
The utility model content
The purpose of this utility model is to provide a kind of reasonable in design, simple in structure, easy to use at the defective that has self-priming pump now to people, can directly extract the novel sucking pump that is lower than any degree of depth water of water outlet out.
The utility model comprises the pump housing and piston, it is characterized in that:
Upper cover is equipped with in a, pump housing upper end portion, capping is equipped with down in the underpart, the pump housing is communicated with the upper and lower part with the piston cavity of the pump housing respectively on one side by upper and lower two intake pipes of three-way pipe on one side, and the relative another side of the pump housing is communicated with the piston cavity another side upper and lower part of the pump housing respectively by upper and lower two outlet pipes of three-way pipe.
B, piston are loaded in the piston cavity of the pump housing, and envelope that connecting rod passes upper cover, be fixed on the upper cover is connected with piston by rocking handle.
In addition, sealing plug, ball valve, filter screen are equipped with in the upper and lower two intake pipe ends that are communicated with the piston cavity left side.With the upper and lower two outlet pipe ends that piston cavity the right is communicated with filter screen, ball valve, sealing plug are housed.
During use, the connecting rod top is connected a motor, ato unit, move on the moving piston of shipper pole on the connecting rod, water enters piston cavity by the following intake pipe on the pump housing left side, the ball valve of the lower discharging tube port on the right of the effect lower pump body of hydraulic pressure is closed, water in the piston cavity is discharged by the upper water-out pipe on pump housing the right, when piston moves down, the ball valve of the upper water-out tube opening on pump housing the right closes valve, the last intake pipe water inlet on the left side, the lower discharging tube water outlet on the right, the ball valve of the following intake pipe port on the left side is closed, and is moved up and down repeatedly by piston and finishes the operation of pump drainage water.This self-priming pump also can be used for the operation of pump drainage gas.
Effect of the present utility model
The utility model not only can be lower than the water that exports any degree of depth by pump drainage, and can directly will be lower than the water of water outlet below 14 meters especially and extract out, and also reasonable in design, simple in structure, easy to use, be widely used.
