Abstract
The invention provides a high-low pressure manual power source. According to the high-low pressure manual power source, an operating rod is mounted on a pump body of a high-low pressure combination pump, an oil tank is connected with the pump body, an integrated plunger is mounted inside the pump body, the integrated plunger is connected with the operating rod, an outlet one-way valve and an overflow valve are arranged in a cavity of the integrated plunger, and the high-low pressure combination pump is connected with an unloading valve. According to the high-low pressure manual power source, the integrated plunger is adopted, only one public operation rod is needed, operation processes are simplified, the high-low pressure combination pump and the pressure-limiting overflow valve are independent of each other and are both of a direct-acting steel ball sealing type, the lower pressure pump overflow valve can be controlled automatically and can also be controlled by a high pressure pump to serve as an unloading valve, operation is steady and reliable, and impact is small; due to the fact that the oil tank is directly connected with the pump body, the size is reduced, and the application range is wider; the unloading valve with an external handle is easier to operate.
Description
Technical field
The present invention relates to high low pressure combination hand-hydraulic power source technical field.
Background technique
Hand-hydraulic power source is of a great variety, and discharge capacity, working pressure, structural type are different.Enter in needs F.F.-work, when fine setting heavy duty, need multiple hand-hydraulic power sources to be used in combination, not easy to operate, how assorted pipeline is, installation volume is large.
Summary of the invention
In order to overcome traditional gyropilot function singleness, to use the problems such as inconvenience, poor stability, the invention provides a kind of Ship GPS gyropilot.
The technological scheme that the present invention adopted is for achieving the above object: high low pressure manual power source, fitting operation bar on the pump housing of high low pressure unipump, fuel tank is connected with the pump housing, pump body is installed integral type plunger, integral type plunger attended operation bar, in integral type plunger chamber, be respectively provided with outlet one-way valve and relief valve, high low pressure unipump connects unloading valve.
Described relief valve is straight moving steel ball sealing formula.
Described unloading valve is external handle type unloading valve.
High low pressure manual power of the present invention source, adopt integral type plunger, only need a common operation bar, simplify the operation course, high low pressure unipump pressure limiting relief valve is independent separately, is straight moving steel ball sealing formula, low pressure pump relief valve can automatic control, also can be used as unloading valve by high-pressure service pump control, stable working is reliable, impacts little.Fuel tank is directly connected with the pump housing, reduces volume, apply more extensively, and external handle type unloading valve operates simpler.
Accompanying drawing explanation
Fig. 1 is high low pressure manual power of the present invention source unipump schematic diagram.
Fig. 2 is high low pressure manual power of the present invention source external structure.
Fig. 3 is high low pressure manual power of the present invention source sectional structure chart.
Fig. 4 is high low pressure manual power of the present invention source piston structure figure.
Embodiment
High low pressure manual power source principle of the present invention and structure are as Figure 1-4, fitting operation bar 8 on the pump housing 5 of high low pressure unipump, fuel tank 7 is connected with the pump housing 5, the inner integral type plunger 2 of installing of the pump housing 5, integral type plunger 2 attended operation bars 8, in integral type plunger 2 chambeies, be respectively provided with outlet one-way valve 3 and relief valve 4, high low pressure unipump connects unloading valve.
High low pressure combination of the present invention manual power source adopts integral type plunger 2, plunger diameter is respectively ∮ 9 and ∮ 20, working stroke is 20mm, only needs a common operation bar 8, simplifies the operation course, high low pressure unipump pressure limiting relief valve 4 is independent separately, be straight moving steel ball sealing formula, low pressure pump relief valve 4 can automatic control, also can be used as unloading valve by high-pressure service pump control, stable working is reliable, impacts little.Fuel tank actual volume is 160ml, is directly connected with the pump housing, reduces volume, applies more extensive.For unloading way easy and simple to handle adopts external handle type unloading valve 6.Important technological parameters is: high-low pump discharge capacity is respectively: 1.25 ml and 6.25 ml; High low pressure unipump rated pressure is respectively: 55Mpa and 5Mpa.Operating stem length 600, steering force 18KG.Import and export one-way valve cracking pressure and be 0.5Mpa.Overall weight 3.5KG(is not containing hydraulic oil).
Sectional drawing is high pressure conditions working principle, and low-pressure state principle is identical.When use, mention operating stem 9, plunger 2 chamber inner volumes increase, pressure diminishes, hydraulic oil backs down suction inlet one-way valve 9 under atmospheric pressure, enter second channel 11 plunger cavities by first passage 10, complete oil-absorbing process, depress operating stem 9 plunger cavity inner volumes and diminish, hydraulic oil is squeezed, suction inlet one-way valve 9 is closed, plunger 2 intraluminal fluid force feed pressure are more and more higher, back down outlet one-way valve 3 and realize pressure oil output, and relief valve 4 limits delivery pressure, open off-load higher than set pressure, complete one-off circulation.In the time of low year, 2 pumps are exported simultaneously and are realized rapid movement, (pressure exceedes 5 Mpa) low pressure pump off-load in the time of heavy duty, and high-pressure service pump works independently.
The present invention is described by embodiment, and those skilled in the art know, without departing from the spirit and scope of the present invention, can carry out various changes or equivalence replacement to these features and embodiment.In addition, under instruction of the present invention, can modify to adapt to concrete situation and material and can not depart from the spirit and scope of the present invention these features and embodiment.Therefore, the present invention is not subject to the restriction of specific embodiment disclosed herein, and the embodiment within the scope of all the application's of falling into claim belongs to protection scope of the present invention.
