Abstract
The invention relates to a middle-pressure compressor differential piston element, wherein the piston is formed by upper and lower parts, while the upper part is smaller than the lower part, the upper part is disposed with two-stage or three-stage piston ring and a guiding ring, and the lower part is disposed with a first-stage piston ring and a scraping ring. The invention has compact structure, low cost and small volume which can avoid oil being splashed on the upper piston ring and reduce the lubricant consumption, to reduce the oil in compressed air and pollution. And the compressed air with lubricant from the first stage in second or third compression can improve the condition on the piston ring in the second or third stage to improve the service life and function of the piston ring.
Description
Technical field
The invention belongs to a kind of gas-pressure component, refer in particular to a kind of intermediate pressure compressor stage differential style piston assembly.
Background technique
Piston is the critical component in the compressor, the good and bad working efficiency that directly influences compressor of this modular construction performance.Existing intermediate pressure compressor normally adopts the piston body of single diameter, and piston ring and scraper ring are set on piston body.The compressor piston body of this structure, volume is big, the energy consumption height, the manufacture cost height, consumption of lubricating oil is big when work, and oil content is higher in the air after the compression, befouling environment.
Summary of the invention
The objective of the invention is to overcome the deficiencies in the prior art, thereby a kind of intermediate pressure compressor stage differential style piston assembly is provided,, reduce cost, cut down the consumption of energy, the pressurized air of high-quality, cleaning is provided with reduced volume.
Main solution of the present invention is achieved in that
Piston body of the present invention is made up of upper and lower two-part, and the upper diameter of piston body is less than the lower diameter of piston body; Secondary or three grades of piston rings and guide ring are set on piston body top, first stage piston ring and scraper ring are set in the piston body bottom.
Described first stage piston is equipped with two, and scraper ring is provided with one.
Described secondary or three grades of piston rings are provided with three, and guide ring is provided with one.
Compared with the prior art the present invention has the following advantages:
Because piston body adopts stage differential style, compact structure, the compressor of same pressure and air displacement, it is little to have a volume, low cost of manufacture, energy consumption is low, has so both solved splash system lubrication oil and can't arrive stage differential style piston body upper piston ring position, and this pays a problem that is lubricated to friction to piston ring and cylinder, can make the consumption of lubricant oil drop to minimum again, thereby compressed-air actuated oil content is lowered greatly, reduce pollution, the pressurized air of high-quality, cleaning is provided for the user environment; The pressurized air that has certain lubricant oil of coming from one-level is when carrying out two or three grades of compressions, and the lubricant oil of trace has improved the working environment of two or three grades of self lubricating material piston rings, the performance and the working life of having improved two or three grades of piston rings.
Description of drawings
Fig. 1 is a structural drawing of the present invention.
Embodiment
As shown in Figure 1: piston body 3 is made up of upper and lower two-part, and the upper diameter of piston body 3 is less than the lower diameter of piston body 3.On piston body 3 tops two or three grades of piston rings 5 and guide ring 4 are set.Described two or three grades of piston rings 5 adopt the filled polytetrafluoroethylene material to make respectively with guide ring 4, and wherein two or three grades of piston rings 5 are provided with three, and guide ring 4 is provided with one.Described piston body 3 bottoms are provided with first stage piston ring 2 and scraper ring 1, and first stage piston ring 2 adopts the HT250 material to make with scraper ring 1, and wherein first stage piston ring 2 is provided with two, and scraper ring 1 is provided with one.
Top of the present invention is second piston or three grades of pistons, and the bottom is a first stage piston.Its one-level adopts oily splash lubrication, two or three grades are adopted the little oil lubrication of self lubricating material, after the first stage piston compression, the pressurized air that has certain lubricant oil of coming from one-level is when carrying out two or three grades of compressions, the lubricant oil of trace can improve the working environment of two or three grades of self lubricating material piston rings 5 and guide ring 4, and can improve its performance and working life.
