Technical field
The utility model relates to the integrated composite structure of a kind of efficient constant current fire water pump and motor.
Background technique
Fire water pump adopts motor as drive unit.The live axle of motor generally is connected with the transmission shaft of fire water pump through shaft joint and drives, and not only cost of production is high, and cooperates compactly inadequately, and the intermediate loss is arranged in the usefulness transmittance process.
Summary of the invention
The purpose of the utility model is to provide the integrated composite structure of a kind of efficient constant current fire water pump and motor, and it is compact structure not only, saves production cost, and volume is little, and is in light weight, and the usefulness transmission do not have intermediate loss, and usefulness improves greatly.
The purpose of the utility model realizes through following technological scheme: the integrated composite structure of a kind of efficient constant current fire water pump and motor; It comprises motor case, is located at rotating shaft, the pump body in the motor case and is located at the impeller in the pump body; It is characterized in that: it also comprises the motor front cover between motor case and pump body, and said rotating shaft is passed the motor front cover and extended forward to insert in the pump body and with impeller and be fixedly connected; The rear end of said motor front cover is fixedly connected with motor case, and the front end of motor front cover is fixedly connected with pump body.
The utility model has also carried out following improvement:
The cooperation place of said motor front cover and motor case is provided with the O RunddichtringO.
The cooperation place of said motor front cover and rotating shaft is provided with axle and uses seal ring.
Through O RunddichtringO and the setting of axle with seal ring, improve the water-proof performance of motor greatly, prevent the motor water inlet, make coil short cause damage.
Be connected through a pair of duplex bearing rotational support of arranging vertically between said rotating shaft and the motor front cover, the rear side of motor front cover is provided with the bearing saddle bore that is used for installing duplex bearing.
The motor case rear end also is provided with rear end cover, is connected transmission through bearing between rear end cover and the rotating shaft, is provided with between the ear end face of bearing and the rear end cover to be sheathed on the outer elastic washer of rotating shaft.
Compared to prior art, the advantage of the utility model is:
(1) through integral type design, it is compact structure not only, saves production cost, and volume is little, and is in light weight, and the usefulness transmission do not have the intermediate loss, and usefulness improves greatly;
(2) through duplex bearing is set, increase the area of contact of bearing and machine shaft, the problem that machine shaft ruptures easily when having solved fire water pump pump chamber high pressure has in the past prolonged working life of motor;
(3) setting through resilient pad realizes the automatic adjusting in gap, effectively prevents axial float, has both improved the working life of motor, the proper functioning of the fire water pump that guarantees again to link to each other with rotating shaft.
