Abstract
The invention discloses a method for arranging a piston ring of a piston component. The piston component comprises a piston, wherein a supporting ring is arranged on the piston, two piston circular grooves are respectively formed in the two sides of the supporting ring of the piston. The operating method includes: a piston ring is cut with an opening and machined, and the four piston rings are machined to two straight-placing piston rings and two inclined-placing piston rings; each straight-placing piston ring is provided with a straight-placing ring body with an opening and a first straight-placing opening portion and a second straight-placing opening portion which are arranged on the two sides of the opening; each inclined-placing piston ring is provided with an inclined-placing ring body and a first inclined-placing opening portion and a second inclined-placing opening portion which are arranged on the two sides of the opening; and one finished straight-placing piston ring and one finished inclined-placing piston ring are formed into a set, installed in each piston circular groove of the piston and enabled to stagger the openings of the two piston rings, wherein the straight-placing piston ring is placed on one side close to the end of the piston, and the inclined-placing piston ring is placed on one side close to the supporting ring. Comparing with the prior art, the piston component can solve the problem of the service life of the piston ring of the piston component.
Description
Technical field
The present invention relates to Compressor Manufacturing technical field, especially a kind of collocation method of piston ring of piston assembly of the piston assembly for unlubricated air compressor.
Background technique
Non-lubricated air compressor be by piston assembly in cylinder reciprocating carry out compressed-air actuated, there is a kind of piston assembly, this piston assembly has piston, described piston is provided with supporting ring, twice piston ring groove is respectively equipped with in the both sides of described supporting ring, per pass piston ring groove is all provided with two and has vertical opening piston ring, the opening of two described piston rings staggers installation mutually.In use there are the following problems for the piston ring of such installation: the opening due to piston ring exists the axial leakage path of piston ring and radial leakage path; and continue along with holding of compressor operating time; its piston ring can deform; leakage path can increase gradually and causes Leakage Gas; affect the output tolerance of compressor; need often to shut down more rering, Service Life of Piston Ring is short.
Summary of the invention
Problem solved by the invention is to provide a kind of collocation method of piston ring of piston assembly, to solve the problem of the Service Life of Piston Ring of existing piston assembly.
In order to solve the problem, the technical solution used in the present invention is: the collocation method of the piston ring of this piston assembly, and piston assembly includes piston, and described piston is provided with supporting ring, described piston is respectively equipped with twice piston ring groove in the both sides of described supporting ring
Its configuration operation step comprises:
A, piston ring cutting opening are processed, and respectively four piston rings are processed into two pieces and directly take piston ring and two pieces oblique piston ring,
Described piston ring of directly taking has the straight staple body that is provided with opening and is located at first of its opening both sides and directly takes oral area and second and directly take oral area, and the end face on these two mating faces and described straight staple body two ends of directly taking oral area is set in parallel;
Described oblique piston ring has oblique ring body and is located at the first oblique oral area and the second oblique oral area of its opening both sides, and the mating face of these two oblique oral areas and the end face at described oblique ring body two ends are that oblique angle a is arranged, and the angle of oblique angle a is 20 ° ~ 23 °.
B, describedly directly take piston ring and a described oblique piston ring is a per pass piston ring groove being assembled into described piston by one that completes processing, and the opening of this two pieces piston ring is staggered, wherein said piston ring of directly taking is held in place the nearly first side of described piston end, and described oblique piston ring is held in place nearly described supporting ring side.
Owing to have employed technique scheme, the present invention compared with prior art has following beneficial effect: respectively two pieces is directly taken piston ring and be contained in in piston ring groove with oblique piston ring, directly taking the outside that piston ring is positioned at nearly pressurized gas, making the more smooth and easy axial leakage path with reducing piston ring of the to-and-fro motion of piston; Oblique piston ring is positioned at the inner side of nearly supporting ring, because the mating face of oblique oral area and the end face at described oblique ring body two ends are that oblique angle is arranged, reduce the radial leakage path of piston ring, the Kou Kaichu of piston ring is not affected or less affected by the effect of pressurized gas, extend the time that piston ring deforms, improve the working life of piston ring.
