Description
Technical Field
The utility model relates to the technical field of compressor pistons, in particular to a high-speed reciprocating compressor piston.
Background
Along with the increase of global energy consumption and the development of energy science and technology, the reciprocating compression requirements are higher and higher, the structure is compact, and the space arrangement is convenient. If the whole equipment of the compressor is large, the material cost and the transportation cost are increased, and the arrangement space is also larger. The efficiency of the equipment is improved, the cost is reduced, and the method is the best value target for improvement of all contemporary mechanical equipment industries.
The traditional reciprocating compressor piston component adopts a mode of combining a supporting ring and a piston ring, the supporting ring is used for supporting the weight of the piston component, and the piston ring is used for sealing. If the reciprocating compressor is under the high-speed condition, the piston speed is high, higher requirements are put on the weight of the piston, the weight of the piston is high, the piston speed is limited, and if the weight of the piston is reduced, the piston speed can be correspondingly improved, so that development of a piston capable of meeting the high-speed movement is needed.
Disclosure of utility model
Aiming at the defects of the prior art, the utility model provides a high-speed reciprocating compressor piston, which solves the problem of large quality of a piston component when the reciprocating compressor runs at high speed.
In order to achieve the above purpose, the utility model is realized by the following technical scheme: a piston of a high-speed reciprocating compressor comprises a piston body, wherein a piston rod is inserted into the piston body, a plurality of annular grooves are formed in the outer side of the piston body, piston rings are embedded in the annular grooves, an axial gap is formed between one side wall of each piston ring and the inner side wall of each annular groove, and a radial gap is formed between the inner wall of each piston ring and the inner wall of each annular groove.
Preferably, one side of the piston body is provided with a nut connected with the piston rod, and the other side of the piston body is provided with a pressure-bearing block sleeved on the outer side of the piston rod.
Advantageous effects
The utility model discloses a high-speed reciprocating compressor piston, which has the following beneficial effects:
1. The piston part does not use the traditional supporting ring, only uses the piston ring, has solved the reciprocating compressor under the high-speed condition, the requirement to the weight of the piston part, improve the stress condition of the piston part.
2. The piston part does not use the traditional supporting ring, so that more piston rings can be arranged to compress gas with higher pressure, and the application range of the piston part is widened.
Drawings
Fig.1 is a schematic structural view of the present utility model.
Fig. 2 is an enlarged partial schematic view of the present utility model.
In the figure: 1. a nut; 2. a piston body; 3. piston rings; 4. a pressure block; 5. a piston rod; 6. an axial gap; 7. radial clearance.
Detailed Description
The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.
Referring to fig. 1-2, the present utility model provides a technical solution: a piston of a high-speed reciprocating compressor comprises a piston body, wherein a piston rod is inserted into the piston body, a plurality of annular grooves are formed in the outer side of the piston body, piston rings are embedded in the annular grooves, an axial gap is formed between one side wall of each piston ring and the inner side wall of each annular groove, and a radial gap is formed between the inner wall of each piston ring and the inner wall of each annular groove.
The embodiment is further characterized in that one side of the piston body is provided with a nut connected with the piston rod, and the other side of the piston body is provided with a pressure bearing block sleeved on the outer side of the piston rod.
The components in this case are connected in sequence by a person skilled in the art, and specific connection and operation sequence should be referred to the following working principle, and the detailed connection means are known in the art, and the following working principle and process are mainly described.
Examples: the weight of the piston part is hard to be reduced continuously by the traditional method, the function of the supporting ring is transferred to the piston ring, so that the distance of the supporting ring can be saved by the piston part, the weight of the supporting ring and the piston body is reduced, and the weight of the whole piston part is reduced.
Specifically: the radial clearance at the bottom of the piston ring is reduced to a proper distance, so that each piston ring plays a role in supporting the weight of a piston component, the piston ring has no function, the axial clearance and the radial clearance are filled with gas, the piston ring is tightly abutted against the side surface of the annular groove and the inner wall of a cylinder to play a role in sealing, and the sealing effect of the piston ring is reserved.
It is noted that relational terms such as first and second, and the like are used solely to distinguish one entity or action from another entity or action without necessarily requiring or implying any actual such relationship or order between such entities or actions. Moreover, the terms "comprises," "comprising," or any other variation thereof, are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements does not include only those elements but may include other elements not expressly listed or inherent to such process, method, article, or apparatus. Without further limitation. The term "comprising" an element defined by the term "comprising" does not exclude the presence of other identical elements in a process, method, article or apparatus that comprises the element.
Although embodiments of the present utility model have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made therein without departing from the principles and spirit of the utility model, the scope of which is defined in the appended claims and their equivalents.
