Description
Technical field
The present invention relates to super-pressure pump technical field, more particularly to a kind of gas boosting pump super-pressure piston.
Background technology
Pneumatic gas booster pump is widest field in industry, it combines shirtsleeve operation principle and firm knot
Structure is suitable for most harsh commercial Application, pneumatic gas booster pump is very suitable for increase gas pressure, high pressure gas conveys,
Cylinder charge and scavenging.Super-pressure pump is mainly used for the performance of simulation manufacture ultra-high voltage environment monitoring special material, compressive property.
In super-pressure pump, super-pressure piston plays the role of vital, the sealing means of the super-pressure piston of the prior art in
To seal firmly or soft seal, structure and its simple, super-pressure piston needs move back and forth in high pressure cylinder body, and hard sealing is easy
High pressure cylinder body abrasion is caused to increase, the service life of soft seal is short, and super-pressure leakage is serious, higher to lubricating requirement.
Invention content
The main purpose of the present invention is to provide a kind of gas boosting pump super-pressure piston, the present invention can be solved effectively
The problem of super-pressure piston service life is short at present, super-pressure leakage is serious, lubricating requirement is high and high pressure cylinder body serious wear.
To achieve the above object, the technical solution that the present invention takes is：
A kind of gas boosting pump super-pressure piston, including low-pressure piston and high-pressure piston rod, low-pressure piston middle part have recessed
Slot sets high-pressure bolt rod set in the middle part of groove, and high-pressure piston rod one end connects high-pressure bolt rod set, and the high-pressure piston rod other end is set
Level-one concave station and two level concave station, level-one concave station are socketed sealing copper washer a, guide ring, sealing copper washer from Inside To Outside successively
B, Pneumatic sealing ring, O-ring a and washer set butterfly spring on two level concave station, and high-pressure piston rod top sets locking nut.
Preferably, locking nut and high-pressure piston rod are installed with split pin a, for fixing locking nut, prevent locking locknut
There is stripped thread, loosens.
Preferably, for high-pressure bolt rod set with high-pressure piston rod by pin connection with holes, the both ends of pin with split pin hole are installed with split pin
B, pin with split pin hole fix high-pressure bolt rod set and high-pressure piston rod, split pin b fixed belt hole pins.
Preferably, pin with split pin hole and split pin a in the same plane, ensure high pressure piston when moving back and forth, stress
Uniformly.
Preferably, low-pressure piston outer ring sets O-ring b, and O-ring b reduces the mill that low-pressure piston is subject to low-pressure cylinder friction
Damage.
Compared with traditional technology, the beneficial effect comprise that：The present invention passes through each seal combination is close
It is arranged together, so that high-pressure piston seals effect is enhanced, extend service life, prevent high pressure from divulging a secret, lubricating requirement is low, simultaneously
The present invention is safe and reliable, simple in structure, easy to process, when carrying out high pressure piston reciprocating motion, to the mill of high pressure cylinder body inner wall
Damage is reduced.
