Description
Technical field
The utility model is related to help the structure of stretching, specially a kind of rotary-vane type air conditioning compressor to help the bivalve that blade stretches out
Structure.
Background technology
In rotary blade type compressor usually used at present, the centrifugation generated after rotor rotation is mainly leaned in the stretching of blade
Power and the collective effect of blade groove bottom high-pressure oil are realized.At compressor start initial stage, the foundation not yet in effect of high pressure oil pressure, blade is only
It can stretch out under the action of the centrifugal force.During stretching, the resistance to sliding of blade groove and the inertia force of blade etc. can hinder blade,
So that blade is stretched out slow, flutter, cacophonia are generated in blade notch, thus the pressure of compressor is not built up slowly,
Client's requirement cannot be met.Under extreme case, the time that blade stretches out can reach 30s.During this period of time, Spiralism type pressure
The operating pressure of contracting machine is unstable, and half blade stretched out generates chatter noise.Therefore the blade of rotary blade type compressor how to be allowed quickly to be stretched
Go out, rotary blade type compressor is made steadily to work normally, is always the manufacturing problem of puzzlement.
Utility model content
For the defects in the prior art, the utility model provides a kind of pair that rotary-vane type air conditioning compressor helps blade to stretch out
