Abstract

The utility model relates to a plunger pump part, particularly discloses a high-airtightness double hydraulic plunger pump piston, and belongs to the technical field of plunger pumps. The piston comprises a piston rod, a piston barrel and a piston cylinder, wherein a first piston ring is fixedly arranged at one end of the piston barrel; the piston rod is fixedly arranged on an inner circle of the piston barrel through a fixing ring; the end part of the piston rod penetrates through the first piston ring, and is connected with a second piston ring through a screw; the first and second piston rings are arranged in the piston cylinder in a sliding way. The high-airtightness double hydraulic plunger pump piston is simple, compact and reasonable in structure; double piston rings are adopted, and 45-degree inclined planes are arranged on the peripheries of the piston rings, so that a sealing effect can be effectively achieved, the power consumption can be lowered, noise can be reduced, the working efficiency can be improved, and the high-airtightness double hydraulic plunger pump piston has a good using effect, and is favorable for popularization.

Description

Two formula high-air-tightness hydraulic plunger pump pistons
Technical field
The utility model relates to a kind of plunger pump parts, and a kind of two formula high-air-tightness hydraulic plunger pump piston, belongs to plunger pump technique field specifically.
Background technique
Hydraulic piston pump or solid pump, drive hydraulic jack by hydraulic power bag, and hydraulic jack advances carries cylinder, will carry the material in cylinder to export pipeline to.The piston of hydraulic piston pump is generally divided into single plunger and double-plunger, is specially adapted to high solid content, the long-distance transportation through pipeline of sticky material, its advantage is that operation is highly stable, reliable, but noise is larger, discharge pressure can be up to 130Bar, and discharge capacity can reach 0.5 ~ 500 cubic meter/hour.Be widely used in sewage treatment, Solid Waste Treatment, mine metallurgy, desilting, dredging, petrochemical industry, power plant, the fields such as cement industry.And in prior art, the piston tightness of hydraulic planger pump is also not enough, thereby cause that transmission power is large, high, the inefficient problem that consumes energy, be necessary to improve.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, thereby a kind of two formula high-air-tightness hydraulic plunger pump piston is provided, and sealability is better, has reduced consumed power and noise.
The technological scheme providing according to the utility model, two formula high-air-tightness hydraulic plunger pump pistons comprise piston rod, piston cylinder and piston cylinder, it is characterized in that: first piston ring is fixed in piston cylinder one end; Piston cylinder inner ring is by retaining ring fixed piston rod, and piston rod end is through first piston ring and be connected by screw the second piston ring; First piston ring and the second piston ring are slidably mounted in piston cylinder.
Further, be provided with the first sealing inclined-plane of 45 ° in first piston ring one side circumference, be provided with the second sealing inclined-plane of 45 ° in the second piston ring one side circumference, the first sealing inclined-plane and the second sealing inclined-plane are established dorsad.
Further, piston rod end diameter is greater than piston rod bar portion diameter.
Further, piston cylinder one end connects sealing cover, and piston cylinder one end passes sealing cover.
Further, sealing cover and piston cylinder joint are provided with seal ring.
Compared with the prior art the utility model has the following advantages:
The utility model is simple in structure, compact, reasonable, adopts dual-active plug ring, and the inclined-plane of 45 ° is set at the excircle of piston ring, thereby more can effectively play the effect of sealing, and can reduce power consumption, reduce noise and increase work efficiency, using effect is good, be conducive to promote.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Description of reference numerals: 1-retaining ring, 2-piston rod, 3-piston cylinder, 4-seal ring, 5-sealing cover, 6-piston cylinder, 7-first piston ring, 8-the second piston ring, 9-screw.
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 piston rod 2, piston cylinder 3 and piston cylinder 6, and first piston ring 7 is fixed in piston cylinder 3 one end.Piston cylinder 3 inner rings are by retaining ring 1 fixed piston rod 2, and piston rod 2 ends are through first piston ring 7 and connect the second piston ring 8 by screw 9.
In first piston ring 7 one side circumference, be provided with the first sealing inclined-plane of 45 °, be provided with the second sealing inclined-plane of 45 ° in the second piston ring 8 one side circumference, the first sealing inclined-plane and the second sealing inclined-plane are established dorsad.The first sealing inclined-plane and the second sealing inclined-plane can effectively play the effect of sealing.
Described piston rod 2 end diameter are greater than piston rod 2 bar portion diameters.
First piston ring 7 and the second piston ring 8 are slidably mounted in piston cylinder 6, and piston cylinder 6 one end connect sealing cover 5, and piston cylinder 3 one end pass sealing cover 5.Described sealing cover 5 is provided with seal ring 4 with piston cylinder 3 joints, and seal ring 4 has further been strengthened sealing.
The utility model adopts dual-active plug ring, and the sealing inclined-plane of 45 ° is set at a side circumference of piston ring, thereby more can effectively play the effect of sealing, and can reduce power consumption, reduce noise and increase work efficiency, simple in structure, using effect is good, is conducive to promote.
