A compressor includes a housing, in which a compression chamber is provided; an injection pipeline installed in the housing and configured to inject a fluid into the compression chamber; and a solenoid valve installed on the injection pipeline in the housing and configured to allow or block off the injection of the fluid through the injection pipeline.

Compressor and method of controlling the compressor

A method and an apparatus for environmentally-friendly batch hot-dip coating of high-performance alloy are provided. The method is that workpiece is heated to the process temperature in the heating box with inner gas before galvanizing. The heating box body consist of two or three zones, which are waiting zone, heating zone and post-plating turnover zone (the post-plating turnover zone can be omitted). A zinc pot is arranged in the heating zone, and the zinc pot is configured for hot-dip coating. Workpieces can be processed with zinc or zinc-based alloys. A transporting device is configured to successively transport in a sealed state the workpiece to be processed to the waiting zone, the heating zone, the zinc pot, and the post-plating turnover zone (the post-plating turnover zone can be omitted). The new method realizes hot-dip coating with zinc and other zinc-based alloys without the use of the flux.

Method and apparatus for environmentally-friendly batch hot-dip coating of high-performance alloy

The present invention discloses a scroll compressor. At least two shrink belts (') are provided around the outer periphery of said fixed scroll between the outer periphery of said fixed scroll () and the inner wall surface of the upper cap () of the scroll compressor. The at least two shrink belts are annular, and are in interference fit between the outer periphery of said fixed scroll and the inner wall surface of the upper cap. The at least two shrink belts include a main shrink belt () and an assistant shrink belt (&#x2032;). The main shrink belt and the assistant shrink belt are arranged side by side in the axial direction, that is, in the vertical direction of the fixed scroll, and the main shrink belt and the assistant shrink belt are spaced apart from each other by a distance. In this way, it is allowed to add other special structure (e.g., an additional fluid passage) to the fixed scroll, reduce the deformation of the fixed scroll, and improve the performance and the reliability of the scroll compressor.

Scroll compressor

A scroll compressor is disclosed. The scroll compressor includes an shell, a fixed scroll, a housing and an orbiting scroll. The fixed scroll and the housing are disposed in the shell and fixed relative to each other. An outer peripheral surface of the housing and an inner peripheral surface of the shell are fitted to each other. The orbiting scroll is disposed between the fixed scroll and the housing. The fixed scroll is formed therein with a first injection passage, the housing is formed therein with a second injection passage, a port of the first injection passage and a port of the second injection passage face each other, so that the first injection passage and the second injection passage communicate with each other. The scroll compressor further includes an injection tube assembly, the injection tube assembly is disposed in the shell. The injection tube assembly includes: a tube, and a first tube joint and a second tube joint respectively disposed at two ends of the tube, the first tube joint passes through the shell to communicate with the outside, and the second tube joint is inserted and fitted in the second injection passage.
