Energy indicator used in screw bolt refrigerant compressor

Abstract

The invention relates to an energy instructor of screw refrigerating compressor, wherein the outer end of a screw rod 1 is fixed with a first micro-motion switch cam 2 fixed with a second micro-motion switch cam 4, the rod of a potentiometer 9 is fixed with the first micro-motion switch cam, the rod is also fixed with a first taper gear 8, one end of a second taper gear axle 14 is fixed with a second taper gear meshed with the first taper gear 8 while another end is fixed with a point 13, an instructing base 15 is fixed with a first micro-motion switch 3 and a second micro-motion switch 5, whose rollers are respectively connected with the circumferences of the first and second micro-motion switch cams 2, 4. The invention moves the axle of the sliding valve to be vertical and forward, therefore, user can watch the instructing disc flexibly.

Description

technical field [0001] The invention relates to an energy indicator used as a part of a screw refrigeration compressor, which is installed at the suction end or discharge end of the screw refrigeration compressor. Background technique [0002] During the use of the screw refrigeration compressor, it is often necessary to change the position of the energy adjustment slide valve according to the load change, so that the volume flow of the compressor can adapt to the gas consumption of the actual working condition. In order to accurately indicate the moving position of the slide valve, an energy adjustment indicator component is arranged at the suction end or the discharge end of the screw refrigeration compressor. However, most of the energy indicator panels of conventional screw refrigeration compressors are on the side of the suction end of the screw compressor, and users cannot directly observe them in front of the console, but need to stand on the side of the suction end o...

Problems solved by technology

However, most of the energy indicator panels of conventional screw refrigeration compressors are on the side of the suction end of the screw compressor, and users cannot directly observe them in front of the console, but need to stand on the side of the suction end of the compressor to observe them. It brings great inconvenience to the operation

There are also energy indicators of some screw refrigeration compressors (such as single-unit two-stage screw refrigeration compressors) that need to be set under the coupling between the compressor and the motor, and can only be observed when operating close to the bottom of the coupling, which poses a threat to personal safety. Possesses a great threat, while the observation angle is more restricted
