Abstract
In order to realize measurement and the data capture of scroll machine axial clearance, devise a kind of scroll machine axial clearance detection scroll.This scroll, comprises 8 sensor mounting hole, dynamic vortex tooth, static vortex tooth, Moving plate base plate, quiet plate of trying to get to the heart of a matter, sensor.Major character is: according to dynamic and static scroll wrap engagement situation, formulated the technological scheme of quiet plate sensor aperture of trying to get to the heart of a matter, offered 4 sensor mounting hole respectively in level and vertical radial direction.In order to prevent dynamic vortex tooth to the fretting wear of sensor probe, at sensor mounting hole position processing counterbore.8 sensors through verification are arranged in hole, for detecting the axial clearance of scroll wrap between different compression chamber and the axial clearance along dynamic vortex tooth molded line involute direction diverse location.
Description
Technical field
The utility model relates to a kind of for scroll machine axial clearance detection scroll, realizes the detection of multistage compression chamber inside vortex tooth top axial clearance, is mainly used in the axial clearance test experience of various scroll machine.
Background technique
In scroll compressor working procedure, can be compressed heat, frictional heat, the unequal many factors of pressure, make to form axial clearance between scroll wrap top and scroll bottom plane, scroll wrap engagement place forms radial clearance.The leakage in gap causes compressor air-discharging amount to reduce, and volumetric efficiency reduces, and has had a strong impact on compressor operating performance.At present, all radial clearance and axial clearance are reduced to fixed value when analyzing scroll wrap and leaking and process, also can adopt the margin of error of the compressor performance curves determination axial clearance by actual measurement.There is certain limitation in these two kinds of methods, need to design the scroll directly measuring real-time axial clearance in a kind of energy scroll machine running in accuracy.
Summary of the invention
The purpose of this utility model is to provide a kind of scroll machine axial clearance detection scroll.
The utility model is by realizing with under type: this scroll mainly comprises scroll wrap, quiet plate of trying to get to the heart of a matter, multiple sensor mounting hole, sensor probe composition, it is characterized in that: when different crank angles, according to the engagement situation of dynamic and static scroll wrap, determine that the axial clearance of scroll detects position.Along Moving plate scroll wrap molded line involute direction, fixed scroll has been offered multiple sensor mounting hole, mounting hole processing counterbore near dynamic vortex tooth side, is arranged in mounting hole by the probe of sensor, realizes measurement and the data capture of scroll machine axial clearance.
Of the present utility modelly to have the following advantages: have multiple sensor mounting hole, scroll wrap is avoided to contact and friction with the direct of sensor probe by counter bore structure, the axial clearance of scroll machine different compression chamber inside vortex tooth can be measured simultaneously, the measurement of Moving plate scroll wrap diverse location axial clearance can also be realized.
