Abstract

The utility model discloses a novel external control variable control improved valve body of a large-scale radial variable plunger pump, which is mainly formed by arranging an embedded control plunger hole in a valve body and designing an external control valve oil channel at the outer end of the valve body. The design has the largest bright spots that a control plunger is embedded in a large positive stop body in an external control variable control mode, and the radial size of a pump body is reduced to be suitable for driving in common by double pumps. The preset external control valve oil channel can form multiple variable control modes by matching with different control valves, and the variable control modes can be respectively regulated to lead two pumps to be connected and use one drive motor in common for installation. The valve body respectively regulates the pressure, the flow and the variable modes according to different needs of the system, saves the installation space and can save the power to the maximum according to different needs.

Description

The novel external control type Variable Control of large-scale radially Variable plunger pump modified model valve body
Affiliated technical field
The utility model relates to a kind of constitutional detail-valve body of hydraulicdriven dynamical element, the novel external control type Variable Control of particularly a kind of large-scale radially Variable plunger pump modified model valve body.
Background technique
At present, traditional radial plunger pump complicated integral structure, processing difficulties is subjected to the restriction of processing conditions, promotes difficulty, unstable properties, easy to leak, the valve body flow operating mode demand that can not adapt to big flow system less than normal, and can not external control.
Summary of the invention
Problem to be solved in the utility model is, overcomes the deficiencies in the prior art, and the novel external control type Variable Control of large-scale radially Variable plunger pump modified model valve body is provided, and can realize external control type Variable Control mode.This part is that main material is made by HT300, and through special heat treatment, has stronger wear resistance, and simple in structure, high pressure resistant.
The technological scheme that its technical problem that solves the utility model adopts is: the valve body body that is made into one, and design has built-in control plunger hole in it, and its outer end design has external control valve to cross oily passage and constitute.
This external control type Variable Control mode cooperate transmission shaft and the pump housing, pump cover, big or small limit body, improvement realize that double pump drives altogether.
The novel external control type Variable Control of the large-scale radially Variable plunger pump valve body of a kind of macrotype oilgear pump that the utility model provides, can realize external control type Variable Control mode, comprise that the big limit body of external control type designs and reserves attachment face and takes over oil passage structure outward for split, be fit to connect different external control valves, form multiple Variable Control mode.
The novel external control type Variable Control mode of macrotype oilgear pump designs, and is to utilize the external valve of reservation attachment face of whole structure and side and inner complete pre-pressure of the spring to regulate good stability.
External control valve control hydraulic oil enters external control type Variable Control mode from inlet during work, variable piston overcomes the spring force work done, open external control type Variable Control mode restriction, produce a pressure drop, make spool move sealing restriction by spring force this moment, act on repeatedly until reaching balance, make pump play the variable effect.
The beneficial effects of the utility model are, realize that in conjunction with the improvement of the pump cover that drives flange altogether, pintle double pump (three pumps) drives altogether, helps energy saving.
Whole external control type Variable Control mode structure increases sealing effect, and pre-pressure of the spring is regulated completely, good stability.Limit body need not change, and helps generalization.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 has external control valve to cross oily channel plane structural representation for design of the present utility model.
Fig. 2 is a cross-sectional view of the present utility model.
Accompanying drawing number is: 1. valve body body, and 2. built-in control plunger hole, 3. external control valve is crossed oily passage.
Embodiment
Referring to Fig. 1, Fig. 2, the valve body body (1) that is made into one, design has built-in control plunger hole (2) in it, and its outer end design has external control valve to cross oily passage (3) and constitute.
This modified model valve body external control type Variable Control mode cooperate transmission shaft and the pump housing, pump cover, big or small limit body, improvement realize that double pump drives altogether.
The novel external control type Variable Control of the large-scale radially Variable plunger pump modified model valve body of a kind of macrotype oilgear pump that the utility model provides, can realize external control type Variable Control mode, comprise that the big limit body of external control type designs and reserves attachment face and takes over oil passage structure outward for split, be fit to connect different external control valves, form multiple Variable Control mode.
The utility model compared with prior art has significant advantage and beneficial effect:
The utility model has increased intensity through Overheating Treatment and has reduced cost, and it is simple in structure, and easy processing is high pressure resistant, and assembling is easier to, and is non-leakage.
Owing to do not change the relevant size of other related parts, but tolerance fit optimized, help standardization and unitized work, for the end user, can improve original performance and system optimization with less reforming cost.
Improvement in conjunction with the pump cover that drives flange altogether, pintle realizes that double pump (three pumps) drives altogether, helps energy saving.
Whole external control type Variable Control mode structure increases sealing effect, and pre-pressure of the spring is regulated completely, good stability.Limit body need not change, and helps generalization.
