Description

A kind of suction pump

Technical field

The utility model relates to a kind of water pump, particularly a kind of suction pump with self-absorption function.

Background technique

Rural area, city or the employed suction pump of building site part domestic water generally all are to adopt hand-operating pressure pump at present, are single pump housing piston reciprocating types.In use, must add the starting diversion in advance, just can draw water, piston stroking upward is mentioned underground deep water in the pump housing when drawing water, water when descending in the pump housing is opened valve by the piston duct and is flushed to piston top, naturally flow out from pumping hole, this pressure pump has only the suction journey, and does not have lift, flow is little, pressure is little, can make general domestic water, can not be used for sprinkling irrigation and a large amount of water.

Summary of the invention

The purpose of this utility model is that proposition is a kind of simple in structure, only needs to inject the start cycles diversion in the forward direction pump that draws water first, draws water once more and need not repeat to add the self-priming suction pump that water can draw water, in addition, improved also and can be increased the flowing pressure that draws water, raising lift, the purposes of expansion suction pump.

The utility model take technological scheme be:

This suction pump, comprise pump bracket with. place the pump housing and setting-out mechanism on the pump bracket, also comprise the water-storing device that is installed on the pump bracket, this water-storing device contains water tank, the water tank side wall upper part is established suction valve, the bottom has that set safety check is communicated with bottom aqueduct and the pump housing, and water tank inside or outer installment have intake pipe, and intake pipe is suitable for reading to be lower than the water tank top.

Described setting-out mechanism comprises piston, connecting rod and depression bar, and piston and connecting rod place in the pump housing, and depression bar is connected with connecting rod outer end hinge, and the fulcrum of depression bar places pump housing top.

The safety check that described pump housing bottom is provided with is in the water inlet that is communicated with the aqueduct of water tank.

This suction pump is provided with water tank, when drawing water first, can inject the starting diversion to water tank, close suction valve then by suction valve, the starting diversion that adds water tank enters the pump housing by aqueduct, and the pump housing water surface and the water tank water surface maintain an equal level owing to siphonage and be lower than the suitable for reading of intake pipe.In the process of setting-out mechanism extracting water, the negative pressure that underground flow overcomes the formation of water tank water surface top enters water tank from intake pipe, is pumped to then in the pump housing and discharges thereafter.Draw water after the end, must open suction valve air is entered, the water of intake pipe falls into underground, and the water in the water tank and the pump housing is retained, and when drawing water once more, suction valve cuts out, and just can draw water.Thereby reach the purpose of " diversion is drawn water all the life ".

The utility model improves on the basis of above technological scheme and sets up corresponding establishment and also can improve pumping lift.Can the sealing pump cover be set on the pump housing top of aforementioned suction pump specifically, this pump cover sidewall sets out the mouth of a river; Setting-out mechanism improves and is set to piston, connecting rod, fork and depression bar, fork one end is connected with connecting rod link, the fork the other end is established coupling shaft and is fixedlyed connected with fork, this coupling shaft two end supports is on the end cover of described sealing pump cover left and right side wall, this coupling shaft one end end cap sealing, its other end stretches out the fixedly connected depression bar of end cover.Because the excellent sealing of sealing pump cover and fork and the sealed at both ends end cap of depression bar coupling shaft, when this suction pump drew water, the stream that draws water was full of the sealing pump cover from its sidewall water outlet ejection, and the current lift is greatly improved.

This pump also can be used wind-force, waterpower, electromechanics or animal power and be used as power to drive and draw water except that manpower drives.

The utility model is to design on the basis of traditional water pump, the tradition water pump is all must add diversion earlier when drawing water at every turn, and the utility model is only need inject the start cycles diversion first, re-use later on and need not add diversion again and can draw water, realized the purpose that " diversion is drawn water all the life " self-priming draws water.Modified model also can improve pumping lift, has enlarged using scope, and available this pump carries out extracting vacuum to container, obtains purposes widely, and application value is arranged.
