Abstract

The utility model discloses a kind of oil hydraulic pump, it comprises cam, piston, cylinder body, spring, the first pipeline, second pipe, the first one-way valve, oil cylinder, described piston one end is connected with described cam, the described piston the other end is connected with cylinder body, arranges spring between piston and cylinder body, the cavity at spring place, cavity is connected with the first pipeline, described first pipeline is connected with second pipe, described second pipe is arranged the first one-way valve, and described second pipe is connected with oil cylinder.A kind of oil hydraulic pump of the present utility model, fuel tank communicates with air, opens the power of one-way valve on in-line when this is oil suction, and this cyclically-varying by sealed volume cavity volume, the oil hydraulic pump realizing oil suction and force feed is called displacement pump, pressure good stability.

Description

A kind of oil hydraulic pump
Technical field
The utility model relates to mechanical-hydraulic technical field, is specifically related to a kind of oil hydraulic pump.
Background technique
In prior art, oil hydraulic pump is the dynamical element of hydraulic system, is by motor or motoring, from hydraulic oil container, sucks fluid, and mineralization pressure oil is discharged, and delivers to a kind of element of executive component.Oil hydraulic pump is divided into gear pump, plunger pump, vane pump and screw pump by structure.For hydraulic transmission provides a kind of hydraulic element of pressurized liquid, it is the one of pump.Its function is the pressure energy mechanical energy of power engine (as motor and internal-combustion engine etc.) being converted to liquid.The factor in working life affecting oil hydraulic pump is a lot, to use with some and pump the operation in the selecting of relevant first (as coupling, oil purifier etc.), trial run and run process etc. also relevant except pump design itself, the factor that manufactures are outer.The working principle of oil hydraulic pump is the change that motion brings pump chamber, thus compressed fluid makes fluid have pressure energy.
Summary of the invention
For the deficiency that prior art exists, the utility model provides a kind of oil hydraulic pump of pressure good stability.
To achieve these goals, the utility model realizes by the following technical solutions:
A kind of oil hydraulic pump, it comprises cam, piston, cylinder body, spring, the first pipeline, second pipe, the first one-way valve, oil cylinder, described piston one end is connected with described cam, the described piston the other end is connected with cylinder body, arranges spring between piston and cylinder body, the cavity at spring place, cavity is connected with the first pipeline, described first pipeline is connected with second pipe, described second pipe is arranged the first one-way valve, and described second pipe is connected with oil cylinder.
Further, described first pipeline arranges the second one-way valve.
The beneficial effects of the utility model:
A kind of oil hydraulic pump of the present utility model, fuel tank communicates with air, opens the power of one-way valve on in-line when this is oil suction, and this cyclically-varying by sealed volume cavity volume, the oil hydraulic pump realizing oil suction and force feed is called displacement pump, pressure good stability.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model oil hydraulic pump.
Embodiment
The technological means realized for making the utility model, creation characteristic, reaching object and effect is easy to understand, below in conjunction with embodiment, setting forth the utility model further.
As shown in Figure 1, a kind of oil hydraulic pump, it comprises cam 1, piston 2, cylinder body 3, spring 4, first pipeline 6, second pipe 7, first one-way valve 8, oil cylinder 9, described piston 2 one end is connected with described cam 1, described piston 2 the other end is connected with cylinder body 3, spring 4 is set between piston 2 and cylinder body 3, the cavity 5 at spring 4 place, cavity 5 is connected with the first pipeline 6, described first pipeline 6 is connected with second pipe 7, described second pipe 7 is arranged the first one-way valve 8, described second pipe 7 is connected with oil cylinder 9.
Described first pipeline 6 arranges the second one-way valve 9.
More than show and describe basic principle of the present utility model and major character and advantage of the present utility model.The technician of the industry should understand; the utility model is not restricted to the described embodiments; what describe in above-described embodiment and specification just illustrates principle of the present utility model; under the prerequisite not departing from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
