Description
Technical field
The utility model relates to a kind of motor, particularly about a kind of water cooling motor.The utility model is applicable to the water pump auxiliary motor.
Background technology
The water cooling motor is to utilize aqueous medium in the water pump passage to the motor cooling that circulates, water-cooled machine as publication number CN201001069, on motor housing, be fixed with the stainless steel sleeve, form sealed cavity between motor housing and the stainless steel sleeve, have inlet opening and backwater hole on the cavity; Inlet opening and backwater hole are opened on the bottom end cover between motor housing and the stainless steel sleeve, and the cooling water return-flow catheter is installed on the backwater hole; It is affixed to pass through flange between motor housing and the stainless steel sleeve, and at motor housing and stainless steel sleeve junction the O RunddichtringO is installed.Cooling circulating water is then by in the cavity between cooling water inlet opening inflow motor housing and the stainless steel sleeve, cooling circulating water flows in the outer circulating water device of motor by return port, in motor, remove radiator fan, reduced the operation noise of motor, improved cooling effect.Its major defect is: motor housing generally adopts pig iron material, and motor stator magnetic field is not had shielding action, magnetic field is entered between motor housing and the stainless steel sleeve form sealed cavity, the production electromagnetic sound; And the pig iron easily gets rusty in aqueous medium, and iron rust produces pumped (conveying) medium and pollutes, and this pollution is unallowed to the demanding operating mode of medium degree of purity.
Summary of the invention
The purpose of this utility model is the shortcoming that exists at prior art, provides that a kind of operation noise is low, efficient is high, to the free of contamination water pump of medium low noise water-cooled machine.
The technical solution of the utility model comprises rotor, stator, rotating shaft, bonnet and adpting flange, rotor is inlaid in the rotating shaft, one end of rotating shaft is inlaid in the bearing of bonnet, the bearing that the other end passes in the adpting flange is fixedlyed connected with pump shaft, mainly be that stator is inlaid in formation motor housing in the stainless steel cylinder, these stainless steel cylinder two ends are fixedly welded on respectively on the inner round wall of stator flange, welding one stainless steel sleeve between the cylindrical wall of two stator flanges, form annular seal space between the stator flange at this stainless steel sleeve and stainless steel cylinder and two ends thereof, the stator flange at stainless steel cylinder two ends is connected by screw with adpting flange with the bonnet flange respectively, two stator flanges are enclosed planar towards the end face of annular seal space one side, and the stainless steel sleeve is provided with water inlet and delivery port.
The beneficial effects of the utility model are that motor housing is made up of the stainless steel cylinder, be connected by welded seal between the stator flange at stainless steel cylinder, stainless steel sleeve and two ends, can effectively shield electromagnetism, reduce electromagnetic sound, have that the operation noise is low, efficient is high, to advantages such as medium are pollution-free.
