Description
Technical field
The present invention relates to a kind of parts of axial piston pump, especially relate to a kind of cylinder body that is used for microscopic performance test of plunger pair.
Background technique
The axial piston pump motor is one of of paramount importance dynamical element in the Hydraulic Field, and its plunger cavity is that the plunger to-and-fro motion produces oil suction and presses oily working area.The plunger cavity of common axial piston pump motor processes in cylinder body.Cylinder body as seven common plunger pumps is exactly thereon to process seven cylindrical plunger cavitys being circle distribution according to the design distribution radius by a cylindrical bar on its interface.Therefore the cylinder body of common axial piston pump motor is the structure of integral type, as shown in Figure 1, owing to there is not rational space mounting sensing equipment, is difficult to any single plunger cavity in it is carried out omnibearing testing property.Therefore traditional experimental technique mainly is following several method:
1, static single plunger structure.Be exactly to process a single plunger cavity separately, static is installed on the experimental stand, and the plunger state that fluid passes through under a certain state in plunger cavity can detect to be studied.The Missouri Columbia University of the Zhejiang Polytechnical University and the U.S. all builds such experimental setup.Such device and the actual interior structure of plunger pump differ greatly, and can not realize the function of plunger pump basically, just single parts are studied qualitatively.Narrow limitation is bigger.
2, half dynamic single plunger structure.Still process a plunger cavity separately and be fixed on the frame, driving plunger by mechanisms such as crank-connecting rods can slide in the plunger cavity, thus the situation when plunger work is simulated in the to-and-fro motion that realizes plunger.The RWTH of Germany developed so a kind of experimental setup.But owing to be the work of single plunger, and do not have the turning effect of plunger, therefore the work with actual plunger pump motor still has a certain distance.
3, approximate dynamic single plunger structure based on the thought of model pump, adopts single plunger, single plunger is fixed, thereby the swash plate rotation drives plunger and slides in the plunger cavity, and by the frictional force of swash plate the turning effect of plunger is added, so operating mode is more near reality.The Purdue University of the U.S. has developed such Laboratory Furniture.But this experimental setup is still considered mutual disturbance and the distributing construction between the plunger and is had certain narrow limitation owing to failing.
Development along with the microsensor technology, thought based on model pump, under the situation that does not change the plunger pump structure substantially, the plunger cavity inside of plunger pump is carried out the technical development of testing property, press for a kind of novel cylinder body of exploitation, make it possible to carry out testing property for plunger cavity comprehensive.
Summary of the invention
The object of the present invention is to provide a kind of cylinder body that is used for microscopic performance test of plunger pair, around can making the plunger cavity circumference certain test space is arranged, sensing equipment can be installed its internal performance is tested, and guarantee the function that it can realize original cylinder body.
The technical solution adopted for the present invention to solve the technical problems is:
Comprise several rod assemblies, flow end dunnage, flow panel, several plunger cavity tubes, plunger end dunnage with the identical seal ring of plunger cavity tube number; With several plunger cavity tubes that branches such as circumference are arranged, the shaft shoulder that has an end of seal groove is pressed on the flow end dunnage, and shaft shoulder seal groove and thrust plate pressing plate seal by seal ring simultaneously, and flow panel and flow end dunnage are consolidated.Plunger cavity tube lower end straight cutting is in the circular hole of plunger end dunnage, and plunger end dunnage and flow end dunnage combine by rod assembly.The plunger cavity tube is owing to adopt tubular construction, makes in the whole cylinder body for forming the space that sensing equipment can be installed around any two plunger cavity tubes.
The useful effect that the present invention has is: by cylinder body of the present invention, realized the thought based on model pump, comprehensive testing property is carried out in the plunger cavity inside to plunger pump under the situation that does not change the plunger pump structure substantially.The present invention is along with people's deeply producing the research of plunger pump motor, make the people can be further to the research in the plunger pump motor plunger cavity, the present invention has realized the exchange test of sphere flow and plane flow, realized plunger cavity circumference 360 degree pressure, temperature, oil slick thickness, frictional force is isoparametric surveys, make and can simulate the testing property that actual working conditions is carried out plunger cavity at the plunger pump motor.The present invention all adopts Der Grundsatz der Maschinen design, reliable performance; The ingenious design and the application of integral mechanical structure make compact structure, volume-diminished.

Embodiment
The invention will be further described below in conjunction with accompanying drawing.
As shown in Figure 2, this new-type housing assembly is mainly by rod assembly 1, flow end dunnage 2, and flow panel 3, plunger cavity tube 4, plunger end dunnage 5, seal ring 6 constitutes.Rod assembly 1 is made of bolt, nuts and washers.Flow end dunnage 2 and flow panel 3 are connected by bolt, and plunger cavity tube 4 links together by shaft shoulder structure and flow panel, and seals by seal ring between the two, prevents that unexpected the leakage from producing.Plunger cavity tube 4 and plunger end dunnage 2 directly cooperate and get final product.Flow end dunnage 2 and plunger end dunnage are by the rod assembly pretension.
Described flow panel 3 outer surfaces are plane or concave spherical surface.Described several rod assemblies 1 are screw, nuts and washers is formed.Described several plunger cavity tubes 4 are 5～9.
Adopt split-type structural, plunger cavity is relatively independent, plunger end and flow end are relatively independent, the plunger cavity barrel structure is separated each plunger cavity, the distance of each plunger cavity tube is exactly the installing space of sensing equipment, adopt rod assembly to realize each assembly of cylinder body is fixed up, can realize certain intensity and rigidity.
This device is coupled together by rod assembly by flow end assembly and plunger end assembly: the flow end modular construction of being made of cylinder body flow panel, flow end dunnage, plunger cavity tube and seal ring; Constitute the plunger end modular construction of cylinder body by plunger cavity tube and plunger end dunnage.The plunger end modular construction of this cylinder body and flow end modular construction couple together by the rod assembly that is made of bolt, nuts and washers.Each plunger cavity tube adopts tubular construction to be installed on the flow end assembly, and isolates certain installing space mutually.Plunger cavity tube and flow end assembly have static seal to ensure can not produce leakage.
As shown in Figure 2, the flow panel 3 among the design can be dismantled, thereby this housing assembly can change the structure of flow panel 3 very easily, mainly is plane structure and concave spherical surface structure, therefore provides convenience for repeatedly improving test, has saved cost; The isolation design of the design's plunger cavity tube 4 makes it that sensing equipment installing space and cabling space arranged each other, and plunger cavity tube 4 also is conveniently to exchange, can realize other Special-Shaped Column such as cydariform plunger are filled in capable experimental study, kill two birds with one stone, very convenient.
