Description
Technical Field
The utility model relates to a plunger, concretely relates to plunger for variable high pressure plunger pump.
Background
The existing inclined shaft pump (motor) is driven by a cylinder body through a plunger driving shaft or a shaft through a plunger driving cylinder body, so that radial force is completely born by the plunger, and when the plunger moves in a cylinder body hole, the radial force of the plunger in the moving direction of the cylinder body is large, and the plunger is easy to wear on one side, so that the phenomena of cylinder pulling, easy breakage of the plunger and the like are generated. Driven by the plunger, the rigidity requirement on the plunger is very dependent, and the plunger design of all the inclined shaft pumps is heavier, so that the rotating speed of the pump (motor) is improved, noise pollution is caused, and the overall efficiency of the pump is influenced.
In addition, the existing connecting mode of the plunger of the inclined shaft pump and the main shaft mostly adopts screw pressure for a return disc, the processing difficulty is large, the distance of a ball center is difficult to control, the abrasion is fast, the gap is enlarged, the noise is increased, the high-pressure oil passes through the small hole in the middle of the plunger to lubricate the ball socket, the gap is leaked greatly, and the dry friction damage is faster if the small hole is not arranged.
Disclosure of Invention
The purpose of the invention is as follows: the utility model aims at overcoming the not enough among the prior art, provide a working gap is little, and lubricated effect is better, reduces the processing cost, improves life's slide inclined axis variable high pressure plunger pump plunger.
The technical scheme is as follows: in order to solve the technical problem, a slide inclined axis variable high pressure plunger pump plunger, it includes the plunger main part one end is equipped with the bulb, the other end is equipped with the sealing ring connector, bulb, plunger main part and sealing ring connector integrated into one piece be equipped with two helicla flutes on the bulb, they divide into helicla flute I and helicla flute II, helicla flute I and helicla flute II set up relatively, the width one end of helicla flute is established to the bulb in upper portion, the junction of establishing to bulb and plunger main part to the other end be equipped with the sealing ring spread groove on the sealing ring connector be equipped with the sealing ring in the sealing ring spread groove.
Further, the sealing ring is a rigid sealing ring.
Furthermore, an included angle is formed between the length side edge of the spiral groove and the center line of the ball head on the same side of the spiral groove.
Has the advantages that: compared with the prior art, the utility model, it is showing the advantage and is: the utility model discloses overall structure sets up rationally, it includes the bulb, plunger main part and sealing ring connector, be equipped with the helicla flute on the bulb, upper portion in the bulb is established to width one end of helicla flute, the junction to bulb and plunger main part is established to the other end, there is the contained angle between the length side of helicla flute and its bulb central line with one side, this groove can let the abundant lubrication of plunger bulb in the main shaft ball socket, can be no more than main shaft plane and plunger central line contained angle 25 with the plunger again, put into the main shaft ball socket with the plunger, the working gap is little, use reliably, this product processing cost is low, accord with the in-service use requirement.
