Abstract
The utility model relates to a two-stage superhigh pressure hand-operated oil pump, which belongs to the field of hand-operated tools. The utility model mainly comprises a pump body 2, an oil storing chamber 1, a hand-operated plunger pump, and a pressure oil output end P, wherein the hand-operated plunger pump is a high and low pressure two-stage plunger pump 6. The oil storing chamber 1 is divided into three paths, path A, path B, and path C after passing through a one-way oil inlet valve 3, wherein the path A is connected with a low pressure chamber 61 of the plunger pump 6, the path B comes back to the oil storing chamber 1 through a low pressure oil return valve 4, and the path C is divided into two paths, path D and path E after passing through a high pressure oil inlet valve 5. The path D is connected with a high pressure chamber 62 of the plunger pump 6, and the path E is connected with the pressure oil output end P through a high pressure one-way oil outlet valve 9 and is connected with the oil storing chamber 1 through a one-way oil outlet valve 10. The utility model has compact structure and proper size, can be conveniently carried and used, can put out 200 MPa pressure and more than 200 MPa pressure, and can be widely used for naval construction, heavy machinery construction, mining, road construction, material testing and other field operation occasions.
Description
Technical field
The utility model relates to Hydraulic power tools, refers to a kind of high pressure hand-operated oil pump especially.
Background technique
Present high pressure oil pump is generally single-stage pump, and its delivery pressure is about 63Mpa.This pressure as industries such as shipbuilding, heavy-duty machine, mine, road construction, the testings of materials, just seems not enough to some occasion.
Summary of the invention
The purpose of this utility model is to propose a kind of secondary ultrahigh pressure hand oil pump, and its two-stage supercharging oil pump structure of mat can be exported＞the ultrahigh pressure pressure oil of 200MPa.
A kind of secondary ultrahigh pressure hand oil pump of the present utility model, mainly comprise a pump housing 2, one reservoir compartment 1, one manual plunger pump, one pressure oil output terminal P, described hand piston pump is a high low pressure two-stage plunger pump 6, described reservoir compartment 1 is divided into A after by a unidirectional oiling valve 3, B, C three tunnel: wherein the A road links to each other with the low-pressure cavity 61 of plunger pump 6, accumulator 1 is got back to by a low pressure scavenger valve 4 in the B road, the C road is divided into D again after by a high pressure oiling valve 5, E two tunnel, wherein the D road links to each other with the hyperbaric chamber 62 of plunger pump 6, and the E road links to each other with reservoir compartment 1 by the fuel-displaced one-way valve 9 of a high pressure and pressure oil output terminal P and by the one-way valve 10 of draining the oil.
Advantage of the present utility model is: owing to adopt high low pressure secondary plunger pump that delivery pressure is improved greatly, satisfied the demand of the hand-operated tools of ask for something high workload pressure.The utility model compact structure, volume is moderate, carries and uses all very conveniently, can be widely used in the occasion of shipbuilding, heavy-duty machine, mine, road construction, the testing of materials or other field works.
Description of drawings
Now the utility model is described in further detail in conjunction with an embodiment and accompanying drawing thereof.

Fig. 2 is an an embodiment's of the present utility model structural drawing
Fig. 3 is the A-A sectional drawing of Fig. 2.
Among the figure: 1 accumulator, 2 pump housings, 3 in line check valves, 4 low pressure relief valves, 5 high pressure in line check valves, 6 high low pressure plunger pumps, 8 hand levers, the fuel-displaced one-way valve of 9 high pressure, 10 fuel outlet valves, 11 fuel outlet valve handles, 12 lands, 13 cylinder lever connecting rods, P pressure oil output terminal, O return opening.
Embodiment
An embodiment's of the present utility model structure such as Fig. 2, shown in Figure 3.Among the figure, the pump housing 2 one sides are provided with an accumulator 1, and this accumulator 1 is fixed on the pump housing 2 by cylinder lever connecting rod 13 and land 12.One plunger cavity is arranged at the described pump housing 2 tops, this plunger cavity upper half part is the bigger low-pressure cavity of diameter 61, lower half portion is the less hyperbaric chamber of diameter 62, in low-pressure cavity 61, be provided with cylindrical low-pressure plunger, being provided with high-pressure plunger in hyperbaric chamber 62, floats and is located in the chamber of low-pressure plunger bottom in the upper end of this high-pressure plunger.Described low-pressure plunger 61 upper ends link to each other with a manual lever 8.
By Fig. 1, described reservoir compartment 1 is divided into A, B, C three tunnel after by a unidirectional oiling valve 3: path A links to each other with the low-pressure cavity of plunger pump 6, path B gets back to accumulator 1 by a low pressure scavenger valve 4, path C is divided into D, E two tunnel again after by a high pressure oiling valve 5, wherein the D road links to each other with the hyperbaric chamber of plunger pump 6, and the E road is back to reservoir compartment 1 and links to each other by the fuel-displaced one-way valve 9 of a high pressure and pressure oil output terminal P and by the one-way valve 10 of draining the oil.
During work, press hand lever 8, the oil of reservoir compartment 1 flows into respectively in low-pressure plunger chamber and the high-pressure plunger chamber by path A and C, D, after plunger pump 6 superchargings, by path E and fuel-displaced one-way valve 9 pressure oil output.When load, after idle stroke finished, the pressure of output terminal raise, and the pressure of plunger pump output at this moment increases, and reaches working pressure.
