Abstract

The utility model discloses a plunger pump of a single-cylinder plug cylinder for an experiment. The plunger pump comprises an oil draining valve, a spring, a cylinder body, an oil suction valve, an oil tank, a plunger, an eccentric shaft and a sealed oil cavity. The eccentric shaft is a cam mechanism, the cylinder body is provided with a horizontal channel and a vertical channel, the intersection portion of the horizontal channel and the vertical channel forms the sealed cavity, the plunger is placed inside the horizontal channel, one outer circle end of the plunger abuts against the cam surface of a cam, the other end of the plunger is connected with one end of the spring, the other end of the spring is connected with the inner portion of the cylinder body, one end of the vertical channel is connected with the oil draining valve, the other end of the vertical channel is connected with the oil suction valve, and the oil suction valve is connected with the oil tank. According to the plunger pump of the single-cylinder plug cylinder for the experiment, one cylinder body of the plunger pump is retained, the structure of the plunger pump can be simplified, and a good experiment result can be guaranteed.

Description

The plunger pump that is used for the single cylinder plug cylinder of experiment
Technical field:
The utility model relates to the hydraudynamic drive research field, is specifically related to a kind of plunger pump for the single cylinder plug cylinder of testing.
Background technique:
At present, in present hydraulic transmission element, plunger pump is to use one of the widest dynamical element.Plunger pump is the indispensable vitals of most of fluid machines, and its performance has directly determined performance and the quality of whole equipment.Along with the raising of Machine Design manufacture level, more and more higher to the requirement of plunger pump radially, it is little to have proposed volume, in light weight, the efficient height, bearing capacity is strong, life-span is long waits requirement, certainly plunger pump when having above advantage, also have shortcoming as: part is more, complex structure, the manufacture process requirement height, for working environment and medium turbidity test requirement is arranged, cost is higher relatively, therefore makes a plunger pump, make a search for the laboratory, very inconvenient and uneconomical.
How under this background, the efficient of elevator pump and the power loss that reduces pump become the design production engineer's of whole world pump research center.Relation for the rotating speed of studying plunger pump actual displacement and Theoretical flowing capacity and plunger main shaft need carry out analog study to plunger pump, but reciprocating pump has four cylinder body symmetric arrangement, and research is got up very inconvenient.
The model utility content:
In order to overcome above shortcomings part in the prior art, the purpose of this utility model is to provide a kind of plunger pump for the single cylinder plug cylinder of testing, and can simplify the plunger pump structure, and can guarantee good experimental result.
The utility model is achieved by the following technical programs: the plunger pump that is used for the single cylinder plug cylinder of experiment, comprise draining valve, spring, cylinder body, oil sucting valve, fuel tank, plunger, eccentric shaft, seal oil chamber, described eccentric shaft is cam mechanism, described cylinder body is provided with crosspassage and vertical passageway, and described crosspassage and intersection, vertical passageway form sealed cavity, and described plunger is placed in the crosspassage, described plunger one outer nose circle and cam wheel face offset, the described plunger the other end connects spring one end, and the spring the other end links to each other with cylinder interior, and described vertical passageway one end is connected with draining valve, the other end is connected with oil sucting valve, and oil sucting valve links to each other with fuel tank.
Wherein eccentric shaft replaces with cam, and slide block drives plunger motion and replaces with spring.The suction expulsion valve of plunger pump is that plate valve and stem valve all are one-way valves, can be that two one-way valves replace with draining valve and oil sucting valve.In the rotation of eccentric shaft and thrust lower plunger to-and-fro motion in cylinder body of spring.Oil extraction from the draining valve of one-way valve in drive-in step, oil suction from the oil sucting valve of one-way valve in fallback procedures.So just simulated the movement process of plunger pump.
The utility model advantage compared with prior art is: the plunger pump for the single cylinder plug cylinder of testing of the present utility model, having kept plunger pump has a cylinder body, can simplify the plunger pump structure, and can guarantee good experimental result.
Description of drawings:
Fig. 1 is structural representation of the present utility model;
The utility model is described in further detail below in conjunction with accompanying drawing.
Embodiment:
In order further to explain the technical solution of the utility model, the utility model is elaborated below by specific embodiment.
With reference to shown in Figure 1, be used for the plunger pump of the single cylinder plug cylinder of experiment, comprise draining valve 1, spring 2, cylinder body 3, oil sucting valve 4, fuel tank 5, plunger 6, eccentric shaft 7, seal oil chamber 8, described eccentric shaft 7 is cam mechanism, described cylinder body 3 is provided with crosspassage and vertical passageway, described crosspassage and intersection, vertical passageway form sealed cavity 8, described plunger 6 is placed in the crosspassage, and described plunger 6 one outer nose circles and cam wheel face offset, and described plunger 6 the other ends connect spring 2 one ends, spring 2 the other ends and 3 inner linking to each other of cylinder body, described vertical passageway one end is connected with draining valve 1, and the other end is connected with oil sucting valve 4, and oil sucting valve 4 links to each other with fuel tank 5.
Wherein eccentric shaft 7 usefulness cams replace, and slide block drives plunger motion and replaces with spring 2.The suction expulsion valve of plunger pump is that plate valve and stem valve all are one-way valves, can be that two one-way valves replace with draining valve 1 and oil sucting valve 4.At the thrust lower plunger 6 of the rotation of eccentric shaft 7 and spring 2 in 3 li to-and-fro motion of cylinder body.Oil extraction from the draining valve 1 of one-way valve in drive-in step, oil suction from the oil sucting valve 4 of one-way valve in fallback procedures.So just simulated the movement process of plunger pump.
But above-mentioned embodiment is exemplary, is to be the restriction that this patent is comprised scope in order better to make those skilled in the art can understand this patent, can not to be interpreted as; So long as according to spirit that this patent discloses do anyly be equal to change or modify, all fall into the scope that this patent comprises.
