Embodiment Construction

[0021] It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and examples.

[0022] like figure 1 As shown, the present invention provides an embodiment of the sealing ring. The sealing ring of this embodiment includes a body 10, the body 10 has a first end face 11 and a second end face 12, and the first end face 11 and the second end face 12 are along the axis of the sealing ring. Located opposite to each other in the direction, the first end surface 11 and / or the second end surface 12 of the body 10 is provided with an annular concave portion 20 extending along the circumferential direction of the sealing ring.

[0023] During the use of the seal ring, the seal ring is installed between the piston assembly and the cylinder of the screw compressor. During the loading ...

Abstract

The invention provides a sealing ring and a screw compressor with the same. The sealing ring comprises a body (10), wherein the body (10) is provided with a first end face (11) and a second end face (12), the first end face (11) and the second end face (12) are oppositely arranged in the axial direction of the sealing ring, and the first end face (11) and / or the second end face (12) of the body (10) are / is provided with an annular concave portion (20) extending in the circumferential direction of the sealing ring. The sealing ring and the screw compressor with the same solve the problems that in the prior art, a screw compressor is unstable in operation process and high in fault rate.

Description

technical field [0001] The invention relates to the technical field of compressors, in particular to a sealing ring and a screw compressor with the sealing ring. Background technique [0002] In the screw compressor, a cylinder block is provided at one end of the slide valve, and a piston assembly for adjusting the capacity is provided in the cylinder block. In the current technology, a structure of a sealing ring and an O-ring is used to control the piston assembly and the cylinder block. The gap between, so as to achieve the intended purpose of sealing. [0003] Due to the single structure of the O-ring itself, if the O-ring is installed on the piston assembly, the preload between the piston assembly and the inner wall of the cylinder is too large, and the piston assembly will not run smoothly and be stuck; the O-ring Wear and tear will occur after long-term use, and the gap between the piston assembly and the inner wall of the cylinder body will be too large, which will ...
