Abstract
The utility model relates to an air chamber cylinder for an air booster pump and belongs to the technical field of engineering machinery air chamber cylinder. The air chamber cylinder for the air booster pump is characterized in that the air chamber cylinder is cylindrical, a piston ring is arranged in the air chamber cylinder, a contact face of an air chamber cylinder inner wall and the piston ring has a taper, the center of the piston ring is connected with a push rod, and the push rod penetrates out through the other side of the air chamber cylinder. Compared with the prior art, the air chamber cylinder for the air booster pump has the advantages that the air chamber cylinder is made of high-strength aluminum alloy instead of original HT200 pig iron castings, failures caused by retardation, blockage and sealing element abrasion which are caused by corrosion are avoided, and the service life of the air chamber cylinder is greatly prolonged; and rigid cone seal is adopted on the end face of the piston ring, sealing effect becomes good along with pressure increase of the air chamber cylinder, and reliability and durability are effectively improved.
Description
Technical field
The utility model relates to a kind of air booster pump air chamber cylinder body, belongs to engineering machinery air booster pump technical field.
Background technique
The air booster pump is to introduce the production of domesticizing of the U.S.'s Caterpillar engineering machinery eighties in 20th century, and in actual use, because the bad working environments environment of loader, frequent braking requires high to this reliability of products.
To the air chamber cylinder body, original HT200 iron casting that is designed to is prone to situation such as corrosion in the process in long-term.Simultaneously, the sealing between piston ring and the air chamber cylinder body is inaccurate, is prone to gas leakage, thereby causes braking failure.
Summary of the invention
To the problems referred to above that exist in the existing technology, the utility model provides a kind of air booster pump air chamber cylinder body of novel structure.
The technological scheme that the utility model adopts is following:
Air booster pump air chamber cylinder body is characterized in that said air chamber cylinder body is cylindric; Be provided with piston ring in the said air chamber cylinder body; Said piston ring and air chamber inboard wall of cylinder block surface of contact have a tapering, and said piston ring center is connected with push rod, and said push rod is passed by air chamber cylinder body opposite side.
Further, be provided with the spring ring that is cone between said piston ring and the air chamber cylinder side wall.
Further, the material of said air chamber cylinder body is an aluminum alloy.
The utility model air booster pump air chamber cylinder body and is compared in the existing technology, and its beneficial effect shows:
1, air chamber cylinder body material is improved to high tensile aluminium alloy by former HT200 iron casting, has avoided because of retardance that corrosion causes, stuck, and sealing part abrasion and losing efficacy has greatly improved working life.
2, the piston ring end face adopts the sealing of rigidity awl, and along with the pressure increase of air chamber cavity, sealing effect is good more, and reliability and durability are all effectively promoted.
Description of drawings
For the ease of it will be appreciated by those skilled in the art that model utility is further described below in conjunction with accompanying drawing.
Fig. 1 is the structural representation of the utility model.
Embodiment
See also Fig. 1, air booster pump air chamber cylinder body 3, material is an aluminum alloy, is cylindric.
Be provided with piston ring 4 in the air chamber cylinder body 3, piston ring 4 has a tapering 2 with air chamber cylinder body 3 inwall surface of contact, and piston ring 4 centers are connected with push rod 5, and push rod 5 is passed by air chamber cylinder body 3 opposite sides.
Be provided with the spring ring 6 that is cone between piston ring 4 and air chamber cylinder body 3 sidewalls.
Air booster pump, its form are pneumatic jack oil, are applicable to engineering vehicle braking system such as loader, excavator, road roller, and its effect is to change lowpressure into high hydraulic pressure to guarantee brake request.
Above content only is to be given an example and explanation to what the utility model structure did; Under the technician in present technique field described specific embodiment is made various modifications or replenish or adopt similar mode to substitute; Only otherwise depart from the design of model utility or surmount the defined scope of these claims, all should belong to the protection domain of the utility model.
