The elastic membrane is connected with damping device ontology by retaining ring.
Preferably, the exhausting end base is connected with nested type orifice module by positioning bolt.
Preferably, there are four the damping device ontology is arranged altogether, and damping device ontology is uniformly mounted on exhausting end base
Two sides up and down.
Preferably, the positioning bolt is provided with 20 altogether, and positioning bolt is uniformly mounted on male rotor hole and yin turns
The surrounding of sub-aperture.
Compared with prior art, the beneficial effects of the present invention are: the equipment be equipped with by the inside in exhausting end base it is embedding
Shell type orifice module adjusts the shape of axial exhaust port in nested type orifice module, as far as possible according to required interior compression ratio
Energy loss caused by inside and outside pressure ratio difference is eliminated, it is energy saving；By being equipped with positioning spiral shell in nested type orifice module
Bolt, the neither original size of influence exhausting end base, and mechanical seal and the installation of bearing are not influenced, adjustment is convenient and fast, uses
Simply；By being equipped with limit cutting ferrule in the inside of damping device ontology, guarantee that the installation of damping device ontology is not shaken accurately；It is logical
The lower originating party crossed in limit cutting ferrule is equipped with elastic element, damping processing is carried out to exhausting end base, caused by reducing because of vibration
Injury；By being equipped with elastic membrane below block, Flexible change is realized to block and retaining ring, reduces wear damage, is extended
Use the time.
