Abstract
The utility model discloses a displacement control mechanism for a plunger pump. A double-section type servo cylinder is arranged at the rocking bottom of the displacement control mechanism, a mechanical displacement control mechanism for the plunger pump in the prior art is modified into a hydraulic servo control mechanism. The displacement control mechanism is convenient to mount, low in abrasion and small in occupied space, space is effectively saved, and controlling performance of the plunger pump is optimized.
Description
Technical field
The utility model relates to a kind of displacement control mechanism that is used for plunger pump, relates to a kind of stroking mechanism of swash plate plunger pump in particular, is mainly used in the swash plate plunger pump field.
Background technique
What the utility model technology was mainly used is Machining Technology, former project organization is the control of mechanical mechanism discharge capacity, done by Vickers company, in long-term using process, oil hydraulic pump mechanical controller structure in the real work weares and teares especially easily or tightens, and mechanical mechanism is installed very inconvenient.
Summary of the invention
The utility model mainly is intended to solve existing hydraulic plunger pump delivery control mechanical mechanism and easily causes servomechanism that inconvenient and the big shortcoming of wearing and tearing in the course of the work are installed, and a kind of displacement control mechanism that is used for plunger pump is provided.
The servo-cylinder that the position of inventor's use servo-cylinder in the past and the bottom of plunger pump swash plate are provided with two section type has promptly used the two section of single-acting oil cylinders, the design of telescopic cover cylinder.Adopt the two section type oil cylinder, the length after stretching out is enough high, and the height after the withdrawal is lower, and profile takes up room little, has effectively utilized the space of enclosure interior.
The purpose of this utility model realizes in the following manner:
A kind of displacement control mechanism that is used for plunger pump, this control mechanism mainly by variable wave, servo-cylinder, servocontrol hydraulic fluid port constitute, and in the bottom that variable waves the two section type servo-cylinder is set.The inwall of lining as servo-cylinder is set in the cavity of servo-cylinder, is convenient to guarantee the quality of fit of oil cylinder and piston.The top of two section type servo-cylinder connects the servocontrol hydraulic fluid port.
Compared with the prior art, the utility model is modified into Hydraulic Servo Control mechanism with the mechanical displacement control mechanism of the plunger pump of prior art, and used the two section type servo-cylinder in the bottom of waving, have the following advantages: on the one hand, original machinery is controlled the plunger pump that plunger pump has made hydraulic control into, and easy for installation, it is little to wear and tear, improve the class of plunger pump, optimized the control performance of plunger pump; On the other hand, used the two section type servo-cylinder in the bottom of waving, it is little to take up room, effectively conserve space.
Description of drawings
Fig. 1 is the hydraulic control plunger pump.
Fig. 2 is the displacement control mechanism of plunger pump.
Among the figure, 1 is servo-cylinder, and 2 for variable waves, and 3 is lining, and 4 is the servocontrol hydraulic fluid port.
Embodiment
Below in conjunction with accompanying drawing the utility model mode of execution is described further:
As Figure 1-3, the utility model is a kind of displacement control mechanism of plunger pump, this control mechanism mainly by variable wave, servo-cylinder, servocontrol hydraulic fluid port constitute, wave 2 bottom at variable two section type servo-cylinder 1 be set.The inwall of a lining 3 as servo-cylinder 1 is set in the cavity of servo-cylinder 1.The top of two section type servo-cylinder 1 connects servocontrol hydraulic fluid port 4.
In use, from the outward appearance of oil hydraulic pump and on the whole, the original complicated mechanical control mechanism of oil hydraulic pump is substituted by an oil pipe, externally usage ratio or disproportional solenoid valve can the telecontrol oil hydraulic pumps, because the utility model has used the two section type oil cylinder, do not increase the volume of oil hydraulic pump, improved the performance of control mechanism, promptly change machinery and be controlled to be hydraulic control, control more accurately, sensitive, light, and can realize telecontrol.
The foregoing description should not be considered as restriction of the present utility model, but any improvement of doing based on spirit of the present utility model, all should be within protection domain of the present utility model.
Claims (3)
1. displacement control mechanism that is used for plunger pump, this control mechanism mainly by variable wave, servo-cylinder, servocontrol hydraulic fluid port constitute, and it is characterized in that the bottom of waving (2) at variable is provided with two section type servo-cylinder (1).
