In the shell, turned back again to the first half of the drive end bearing bracket in the rear end that the shell is extended in the shell；The copper
The internal face of pipe is smooth, and outside wall surface is screw thread；The excircle of the drive end bearing bracket is described by being bolted in the shell
Drive end bearing bracket is provided with medium inlet and media outlet, and the medium inlet is located at lower half, and the media outlet is located at the first half；
The medium inlet and media outlet are welded with casing, which is provided with sinking step, the sinking step welding
Medium channel pipe；Venting plug is provided at the top of the media outlet；The rear end cap is welded in the rear end of the shell, described
Rear end cap is welded by cylindrical shell and spherical calotte, and the cylindrical shell is connected with the rear end of the shell；The spoiler
To be more than the discount vibram outlet of semicircle, arrangement is that part is arranged along the enclosure proportional spacing, adjacent spoiler
Discount vibram outlet is located at vertical both sides up and down respectively, and the runner in the shell is made to form the passage for the turbulent flow that teeters.
Shell of the present invention is relatively thin housing, can not employ the form installation front-end and back-end of bolt or flange
Component, therefore after first welded and installed noseplate and rear bottom plate, it is possible to opened up on noseplate and rear bottom plate bolt hole or
Flange hole is easily installed other component.
