Description
Technical field
The present invention relates to Compressor Technology fields, in particular to a kind of pump housing and with its compressor.
Background technique
The compression chamber of sliding-vane compressor is being separated by slide plate and cylinder inner wall, so in traditional sliding-vane compressor
In, the relative velocity between slide plate head and cylinder inner wall face is very big, excessive so as to cause friction between the two, influence power consumption with
Performance rubs excessive for a long time, can generate the reliability worn and then influence compressor complete machine.
In order to reduce friction and promote reliability, some schemes optimize the cylinder portion of traditional sliding-vane compressor
Transformation substitutes original air cylinder structure using a bearing.Since the inner ring of rolling bearing can rotate, not compared to fixation
For dynamic cylinder, the relative velocity between slide plate head and bearing inner race be will be greatly reduced, and then friction between the two
Also will sharp fall, thus achieve the purpose that reduce rub and improve reliability.
But such scheme can bring new friction pair, i.e. friction between the end face and flange of bearing inner race.In the slow-speed of revolution
Friction is not obvious when operation, once the excessive situation that rubs will occur in speed of service raising, and aforementioned similar, this may also
It will appear power consumption increase or integrity problem.
