Description

The multifunctional solution press pump

The utility model belongs to the improvement technology of hydraulic hand-pump.

At present, do not have the place of tap water in some factories and city suburbs, generally use a kind of hydraulic hand-pump, the water lifts of using as the rural area; The perhaps oil extractor that uses of factory, its structure is in the tube of the garden of a sealing piston to be housed, and one-way on-off valve is housed on the piston, utilizes vacuum pressure to reach the purpose of suction or oil suction.Advantage is simple in structure, produces easily, and cost is low, and is easy to use; Its deficiency is, poor sealing performance at the bottom of the degree of vacuum, uses effort, and the life-span is short, needs frequent maintenance just can use.When water lifts used in winter, because there is water inside, the bursting by freezing phenomenon often takes place, so that can't use.

For solving the deficiency that above hand-hydraulic is adopted, the purpose of this utility model provides a kind of manual multifunctional oil hydraulic pump, utilizes mechanical structures such as accurate piston and change power thrusts to reach the efficient height, to use the labour-saving purpose.

Structural design of the present utility model is achieved in that this oil hydraulic pump main structure constitutes (as shown in Figure 1) by cylinder body and piston, be characterized in that cylinder body adopts horizontal type structure, it is the cylinder body of a garden shape, horizontal positioned, below cylinder body, be placed with inlet and outlet pipe, with the cylinder body cast solid, mechanical piston is equipped with at the cylinder body center, at the one end piston rod is housed, it is rubber " O " RunddichtringO that piston ring is housed on the piston, piston rod one end is connected with rotating shaft with vertical connecting rod is middle, the connecting rod the other end is connected with the square rotating shaft of fixing, be with in the square rotating shaft and manually remove handle, the termination of cylinder body is fixed with cylinder end caps, parallel turnover water pipe is connected with the cylinder body two ends respectively and forms path below the cylinder body, not connected between two pipelines (as shown in Figure 2), in outlet pipe, two-way outlet valve is housed between the cylinder body two ends, outlet valve is the middle steel ball ball that connects with spring, but move left and right in the valve port of closed at both ends, between water inlet pipe mouth and cylinder body two ends, unidirectional inlet valve is housed respectively, inlet valve is single steel ball ball, with the inlet end is valve port, the other end is connected with the cylinder body water intake, two turnover water pipe belows is the cylinder body base, can be to be bolted to below the ground level on any one horizontal position.

The utility model has following advantage compared with the prior art: simple in structure, adopt accurate piston, good seal performance, use the mechanical linkage transmission, the efficient height, laborsaving, the pump housing can be placed on the following use of ground level, prevents bursting by freezing, is adapted at the north or factory and proposes oil, water lift use.

Detailed structure of the present utility model is provided by following examples and accompanying drawing.

Fig. 1 is a multifunction hydraulic pump structure schematic diagram;

Fig. 1 is a multifunctional solution press pump turnover water pipe structural drawing;

Fig. 1 is a multifunction hydraulic pump cylinder sectional view.

Its structure is by shown in Fig. 1～3, and the outside is a cylinder body 1, and the cast iron casting of making a living becomes, 2 is piston, 3 is the rubber piston ring, but piston move left and right in cylinder body, and 4 is piston rod, 5 is connecting rod, 11 for manually removing handle, middle with square shaft 13 connections, removes moving back and forth, drive the piston move left and right, 6 is intake pipe, and 7 is outlet pipe, and two-way valve alive 8 is housed between outlet pipe 7 and cylinder body 1, two of two-way valves are valve port, communicate with cylinder body 1 two ends respectively, which side piston 2 pushes to, and that valve port is opened, the other end sealing, between intake pipe 7 and cylinder body 1 one-way valve 9 and 10 are housed respectively, piston is pushed the sealing of beyond beyond inlet valve to, and another side is opened, otherwise also same, cylinder body 1 termination with end cap 12 with bolton.
