Abstract
The utility model relates to a two-way hydraulic hand-operated pump, which mainly arranges an oil inlet one way valve and an oil outlet one way valve respectively at both ends of a pump and connect these two one way valves with an oil chamber based on a one way hand-operated pump composed of a pump with an oil chamber, an oil inlet one way valve, an oil outlet one way valve, a piston, a one way piston valve, a piston rod and a pull rod. Wherein, the piston is arranged into the oil chamber between the oil inlet one way valve and the oil outlet one way valve through the piston rod. The one way piston valve is positioned between the piston and the piston rod. Cross section of the piston rod is equal to one third to two thirds of cross section of the oil chamber. During operation, the pull rod drives the piston rod to realize reciprocating type moving and ensure two-way, high-speed and easy pump oil and high efficiency, thus having the advantages of simple structure and technique of production and assembling, etc.
Description
Technical field
The utility model relates to a kind of hydraulic manual pump, particularly a kind of bidirectional hydraulic hand pump.
Background technique
Existing hydraulic manual pump mostly is a shot, both when reciprocating motion of the pistons one time, can only export one time pressure oil, be shot, make the hand pump operating time long, inefficiency, and pump body structure complexity, auxiliary hole is many, and pressure oil easily leaks, its job insecurity, poor reliability, and manufacturing, assembling difficulty are big.
Summary of the invention
The purpose of this utility model is in order to overcome above-mentioned deficiency of the prior art, to design a kind of little, high bidirectional hydraulic hand pump of province's force efficiency of volume with bidirectional reciprocating pump oil.
The purpose of this utility model is achieved in that a kind of bidirectional hydraulic hand pump, comprise the pump housing that is provided with oil pocket, in line check valve, fuel-displaced one-way valve, piston, the piston one-way valve, piston rod and pull bar, the filler opening of in line check valve is connected with fuel tank through oil inlet pipe, the oil outlet of fuel-displaced one-way valve is communicated with oil cylinder through oil outlet tube, described in line check valve and fuel-displaced one-way valve are contained in pump housing two respectively and communicate with oil pocket, piston is in piston rod is contained in oil pocket between in line check valve and the fuel-displaced one-way valve, the piston one-way valve is contained between piston and the piston rod, the piston rod the other end stretches out oil pocket and is connected with pull bar through connecting rod, and the sectional area of piston rod equals the 1/3-2/3 of oil pocket sectional area.
The upper end of described fuel-displaced one-way valve is provided with safety check and is communicated with the filler opening of in line check valve through return tube.
Advantage of the present utility model is:
1. drive by pull bar in using that motion bar can guarantee to come and go two-way fuel feeding when reciprocating, delivery rate is not only fast but also laborsaving.
2. this product can also be assembled with safety check, so just can control the speed of draining the oil according to the specific requirement adjustment.
Description of drawings
Structural representation when Fig. 1 outwards spurs for pull bar;
Structural representation when Fig. 2 inwardly promotes for pull bar.
Among the figure: 1, the pump housing; 2, pull bar; 3, oil pocket; 4, in line check valve; 5, fuel-displaced one-way valve; 6, piston; 7, piston rod; 8, piston one-way valve; 9, filler opening; 10, oil outlet; 11, safety check; 12, return tube.
Embodiment
Accompanying drawing is non-limiting to disclose a specific embodiment of the present utility model, and the utility model will be further described below in conjunction with accompanying drawing.
By Fig. 1, Fig. 2 as seen, bidirectional hydraulic hand pump of the present utility model, its structure comprises the pump housing 1, in line check valve 4, fuel-displaced one-way valve 5, piston 6, piston one-way valve 8, piston rod 7 and the pull bar 2 that is provided with oil pocket 3, the filler opening 9 of in line check valve 4 wherein is connected with fuel tank through oil inlet pipe, the oil outlet 10 of fuel-displaced one-way valve 5 is communicated with oil cylinder through oil outlet tube, it is characterized in that; Described in line check valve 4 and fuel-displaced one-way valve 5 are contained in two of the pump housing 1 respectively and communicate with oil pocket 3, piston 6 is in piston rod 7 is contained in oil pocket 3 between in line check valve 4 and the fuel-displaced one-way valve 5, piston one-way valve 8 is contained between piston 6 and the piston rod 7, piston rod 7 the other ends stretch out oil pocket 3 and are connected with pull bar 2 through connecting rod, in order to ensure bidirectional hydraulic pump oil, need the external diameter design of piston rod is thicker, the 1/3-2/3 that the sectional area of general optional piston rod equals the oil pocket sectional area gets final product.As the sectional area that selects piston rod be about the oil pocket sectional area 1/2 for best.For the ease of adjusting the control speed of draining the oil, can be provided with safety check 11 in the upper end of fuel-displaced one-way valve 5 and be communicated with the filler opening 9 of in line check valve through return tube 12.
During work, pull bar 2 outwards spurs, vacuumize and make the oily oil suction chamber that enters in the oil pocket 3 of in line check valve 4 unlatchings, pull bar 2 inwardly promotes again, and oil is through the oil pocket that goes out of piston one-way valve 8 inflow oil pockets 3, fuel-displaced one-way valve 5 is opened oil and is entered oil cylinder through oil outlet tube, pull bar 2 is outwards pulling again, and in line check valve is opened oil-feed, is same as 8 sealings of piston one-way valve simultaneously, in line check valve is opened fuel-displaced, repeats pull bar 2 inside pushing courses again.
In sum, this Bidirectional hydraulic hand operated pump reaches pull bar and drives piston rod and all go out when reciprocating The purpose of oil has simple in structurely, makes, assembly technology is simple, delivery rate is not only fast but also laborsaving, The advantages such as operating efficiency height.
