Abstract
The utility model relates to a hydraulic plunger, in particular to a single plunger ring structure for a hydraulic plunger pump, and belongs to the technical field of plunger pumps. The single plunger ring structure for the hydraulic plunger pump comprises a plunger, an annular plunger groove is formed in the plunger in the peripheral direction, a plunger ring is arranged inside the plunger groove in a sleeved mode, and one end of the plunger ring is provided with a gap which is completely opened. The outer side face of the plunger ring is an arc surface. The sphere centre of a sphere surface where the arc surface of the plunger ring is located deviates from the center of the plunger ring. The single plunger ring structure for the hydraulic plunger pump is simple, compact and reasonable in structure, the good sealing effect and high volume efficiency are obtained on the basis of motion of an original plunger and a cylinder body piston and on the premise that only one plunger ring is installed on one plunger, and therefore the plunger pump has the advantages of being small in leakage amount, easy to assemble, low in cost, high in efficiency, high in rotating speed, low in noise and small in abrasion.
Description
Technical field
The utility model relates to a kind of hydraulic plunger, and a kind of hydraulic planger pump single plunger ring structure, belongs to plunger pump technique field specifically.
Background technique
In modern hydraulic transmission, hydraulic clino-axial piston pump, because its volume is little, lightweight, specific power is large, is easy to the advantages such as control, is widely used at present in various hydraulic systems.
In prior art, plunger in clino-axis type axial hydraulic planger pump and plunger ring structure are as shown in Figure 4, that three plunger ring 2a are housed in the plunger slot on plunger 1a, it is not very desirable that such plunger ring structure is analyzed from processing, assembling use and the input cost of plunger ring, its difficulty of processing is large, complex process, assembling difficulty, cost is higher.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, thereby provide a kind of hydraulic planger pump single plunger ring structure, by the design improvement to plunger ring, the sealing and the high volumetric efficiency that under the prerequisite of a plunger ring, have obtained are only installed at single plunger, thus can make plunger pump have advantages of leakage less, assembling is simple, cost is low, efficiency is high, rotating speed is high, noise is little, it is little to wear and tear.
The technological scheme providing according to the utility model, hydraulic planger pump comprises plunger with single plunger ring structure, it is characterized in that: on plunger, be along the circumferential direction provided with a circle plunger slot, be set with a plunger ring in plunger slot, plunger ring one end is provided with the fracture disconnecting completely.Described plunger ring outer side surface is arc-shaped surface, and the centre of sphere of the arc-shaped surface place sphere of plunger ring departs from plunger ring center.
Further, fracture inner side is provided with leg-of-mutton gap.
Compared with the prior art the utility model has the following advantages:
The utility model is simple in structure, compact, reasonable, on the basis of original plunger and cylinder piston motion, the sealing and the high volumetric efficiency that under the prerequisite of a plunger ring, have obtained are only installed at single plunger, thus can make plunger pump have advantages of leakage less, assembling is simple, cost is low, efficiency is high, rotating speed is high, noise is little, it is little to wear and tear.

Fig. 2 is plunger ring plan view.
Fig. 3 is plunger ring side view.
Fig. 4 is piston structure schematic diagram in prior art.
Description of reference numerals: 1-plunger, 2-plunger ring, 3-plunger slot, 4-fracture, 5-gap, 1a-plunger of the prior art, 2a-plunger ring of the prior art.
Embodiment
The utility model is further described in connection with the embodiment in accompanying drawing below:
As shown in Figure 1, the utility model mainly comprises plunger 1, is along the circumferential direction provided with a circle plunger slot 3 on plunger 1, is set with a plunger ring 2 for sealing in plunger slot 3.
As shown in Fig. 2 ~ 3, described plunger ring 2 one end are provided with the fracture 4 disconnecting completely, in the time of in plunger ring 2 covers are installed to plunger slot 3, from fracture 4, pull open plunger ring 2, thereby plunger ring 2 covers are installed in plunger slot 3.
Described fracture 4 inner sides are provided with leg-of-mutton gap 5, and the setting of gap 5 is convenient to people and is found fracture 4 to complete installation.
Described plunger ring 2 outer side surfaces are arc-shaped surface, and the centre of sphere of the arc-shaped surface place sphere of plunger ring 2 departs from plunger ring 2 centers, its good airproof performance, and volumetric efficiency is high.
The arc-shaped surface of described plunger ring 2 has higher circularity, and internal leakage, the noise of plunger pump are less.
The utility model is simple in structure, compact, reasonable, on the basis of original plunger and cylinder piston motion, the sealing and the high volumetric efficiency that under the prerequisite of a plunger ring, have obtained are only installed at single plunger, thus can make plunger pump have advantages of leakage less, assembling is simple, cost is low, efficiency is high, rotating speed is high, noise is little, it is little to wear and tear.
