Half portion enters in the shell, is turned back again to the upper half of the drive end bearing bracket in the rear end that the shell is extended in the shell
Portion；The internal face of the copper pipe is smooth, and outside wall surface is screw thread；The excircle of the drive end bearing bracket is connected to the shell
Front end, the drive end bearing bracket are provided with medium inlet and media outlet, and the medium inlet is located at lower half, the media outlet position
In the first half；The middle of the inside of the drive end bearing bracket is provided with lagging, and the lagging is empty by the inside of the drive end bearing bracket
Between be divided into the first half and lower half；The first half is in the middle part of the collection of the medium inlet of the copper pipe, and the lower half is
In the middle part of the collection of the media outlet of the copper pipe；The excircle of the rear end cap is plugged in the rear end of the shell by bolt installation,
Gasket is provided between end cap and shell in the rear；The spoiler is the discount vibram outlet more than semicircle, and arrangement is part edge
It arranges with the enclosure proportional spacing, the discount vibram outlet of adjacent spoiler is located at vertical both sides up and down respectively, makes described outer
Runner in shell forms 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.
