The adopted technical scheme is as follows: the compact hydraulic pump with the regulating function comprises a hydraulic pump and a regulating valve, wherein the hydraulic pump is provided with a first oil inlet and a first oil outlet, a cheese block is simultaneously closely arranged above the first oil inlet and the first oil outlet, the regulating valve is closely arranged above the cheese block, a second oil inlet and a second oil outlet which are matched with the first oil inlet and the first oil outlet are arranged at the lower end of the cheese block, a third oil inlet and a third oil outlet which are matched with an oil inlet of the regulating valve and an oil outlet of the regulating valve are arranged at the upper end of the cheese block, the second oil inlet is communicated with the third oil inlet, and the second oil outlet is communicated with the third oil outlet.
Description
Technical field
The utility model belongs to the oil hydraulic pump technical field, relates generally to a kind of compact hydraulic pump with regulatory function.
Background technique
Oil hydraulic pump is the dynamical element of hydraulic system, its effect is the pressure energy that the mechanical energy of prime mover is converted to liquid, refer to the oil pump in the hydraulic system, it provides power to whole hydraulic system, the structural type of oil hydraulic pump generally has gear pump, vane pump and plunger pump, a kind of hydraulic element of pressurized liquid are provided for hydraulic transmission, are a kind of of pump, and its function is the pressure energy that the mechanical energy of power engine (such as motor and internal-combustion engine etc.) is converted to liquid.
Oil hydraulic pump generally all needs to arrange the pipeline oil circuit that adapts with use occasion in use, when especially needing to use the pressure energy of variable, it must arrange the oil line pipe that adapts, and at oil line pipe modulating valve is set, reach regulating action, progress with regard to generation present tense, each parts is being kept on improving, structurally reach small, and can realize corresponding function, and when using oil hydraulic pump, reduce the laying of oil line pipe in order to simplify equipment out of the ordinary, reduce the cost of company, and the structure of integral device is reduced, must reduce the oil circuit between oil hydraulic pump and the modulating valve.
The model utility content
In order to overcome the deficiencies in the prior art, the utility model provides a kind of compact structure, with regulatory function, saves the oil hydraulic pump that oil line pipe is laid.
For solving the problems of the technologies described above, the technological scheme that the utility model is taked is: a kind of compact hydraulic pump with regulatory function, it comprises oil hydraulic pump and modulating valve, described oil hydraulic pump is provided with the first filler opening and the first oil outlet, above the first filler opening and the first oil outlet, closely be provided with simultaneously and carve piece, carve the piece top and closely be provided with modulating valve.
The described piece lower end of carving is provided with second filler opening and second oil outlet suitable with the first filler opening and the first oil outlet, carve piece upper end and be provided with three filler opening and three oil outlet suitable with modulating valve filler opening and modulating valve oil outlet, the second filler opening communicates with the 3rd filler opening, and the second oil outlet communicates with the 3rd oil outlet.
The beneficial effect that the utility model compared with prior art has is:
Oil hydraulic pump is provided with the first filler opening and the first oil outlet, above the first filler opening and the first oil outlet, closely be provided with simultaneously and carve piece, carve the piece top and closely be provided with modulating valve, arrange at the oil inlet and outlet of oil hydraulic pump and closely to carve piece, make and carve piece and oil hydraulic pump is equivalent to linking together of one, and be provided with second filler opening and second oil outlet suitable with the first filler opening and the first oil outlet carving the piece lower end, carve piece upper end and be provided with three filler opening and three oil outlet suitable with modulating valve filler opening and modulating valve oil outlet, the second filler opening communicates with the 3rd filler opening, the second oil outlet communicates with the 3rd oil outlet, with carving piece modulating valve is communicated with oil hydraulic pump like this, oil hydraulic pump has reached regulating action, when using oil hydraulic pump, also no longer need to lay simultaneously oil line pipe, relatively saved the expenditure of part, reduce departmental cost, and can reduce the structure of equipment component.
