Problems solved by technology

[0007] However, the defect of the traditional penetrating slide vane expander is that since the length of the slide vane has been determined during design and processing, after the expander has been running for a period of time, the end of the slide vane will be worn, so that there is a gap between the slide vane and the inner wall of the cylinder. There will be gaps, which will cause internal leakage of the expander, resulting in reduced machine performance

Embodiment Construction

[0018] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0019] see figure 1 , 3. The present invention includes a cylinder 5 provided with an air inlet 8 and an exhaust port 7, a rotor 2 is arranged in the cylinder 5, a slide plate 1 is arranged on the rotor 2, end covers 41 and protruding parts are arranged on both sides of the cylinder 5 Shaft end cover 42, a sealing end cover 43 is also arranged on the extended shaft end cover 42, two sets of slides 1 installed on the rotor 2, and two sets of slides 1 are installed vertically, the angle between the two sets of slides The working chamber 6 of the expander is formed together with the cylinder and the end cover. The slide 1 is composed of a first small slide 11 with a length of L1 and a second small slide 12 with a length of L2. The leaf spring or cylindrical spring 3 placed between the sheet 11 and the second small sliding sheet 12 has a pre-compressed spring le...

Abstract

The invention discloses a penetration slipping sheet expander with automatic compensation function, belonging to the technical field of refrigeration. The expander comprises a cylinder, a rotor eccentrically collocated with the cylinder, a slipping sheet inlaid in a rotor groove, a bearing block and an end cover, wherein, the slipping sheet is composed of a first small slipping sheet with the length of L1 and a second small slipping sheet with the length of L2; a compression spring is arranged between the first small slipping sheet and the second small slipping sheet; the length of a pre-compressed spring is L2; the total length of a slipping sheet 1 arranged in the cylinder is L1+L2+L3, and the length is the same with the two-point connection of the cylinder passing through the center of gyration, which ensures that two ends of the slipping sheet contact with the inner wall of the cylinder all the time. The invention is characterized in that the expander leakage is lowered and the expander efficiency is improved due to the special structural design.

Description

technical field [0001] The invention belongs to the technical field of refrigeration, in particular to a sliding vane expander, in particular to a through sliding vane expander with automatic compensation function used as a throttling device in a refrigeration system. Background technique [0002] In the current traditional refrigeration device, the refrigerant completes the process of compression, condensation, expansion and evaporation in the refrigeration system. The refrigerant is first compressed into high-pressure vapor in the compressor, released heat in the condenser and cooled into a subcooled (saturated) liquid, expands through the throttle valve, absorbs heat in the evaporator and evaporates into vapor, and then returns to the compressor. In the above cycle process, replacing the throttling valve with an expander is a way to reduce the energy loss in the throttling process. [0003] In the sliding vane rotary machine, a closed volume is formed on the sliding vane...
