Annular groove is offered along its circumference on the side wall of shape cock body, sealing ring is inlaid in annular groove and seals manhole, draws
Ring is fixed on the bottom surface of disc-shaped base.
Further, multiple lead columns are uniformly arranged along the circumference of the first circular groove.
This utility model is sealed manhole with sealing-plug by opening up manhole on the side wall of motor cover,
When needing to dismantle front motor cover, sealing-plug is extracted from manhole first with draw ring, make extraneous air by manhole
Into in electric machine casing, the negative pressure in electric machine casing is eliminated, after electric machine casing external and internal pressure is equal, you can back out bolt light
Remove front motor cover；By arranging lead column in the rear end of front motor cover, open up on electric machine casing and coordinate with lead column gap
Gathering sill, when install front motor cover when, be directed to post and be directed at and insert gathering sill, the first screw and motor on front motor cover
The second screw on housing can be naturally to it, and fast and easy greatly improves efficiency of assembling.
