Abstract
The utility model relates to a motor for a high-efficiency constant-current fire-fighting water pump, which comprises a motor shell, a motor rotating shaft, a front end cover and a rear end cover, wherein the output end of the motor rotating shaft extends out of the front end cover to connect and drive a fire-fighting pump. The motor for the high-efficiency constant-current fire-fighting water pump is characterized in that: the motor rotating shaft and the front end cover are connected in a rotating-supporting mode through a pair of double bearings which are arranged along an axial direction, and the rear side of the front end cover is provided with bearing-seat holes for installing the double bearings. The utility model aims to provide the motor for the high-efficiency constant-current fire-fighting water pump, the problem that the motor rotating shaft is easily broken when the voltage of the pump cavity of the previous fire-fighting pump is high is solved by increasing the contact area of the bearings and the motor rotating shaft, and the service life of the motor is prolonged.
Description
Technical field
The utility model relates to a kind of efficient constant current fire water pump motor.
Background technology
Because fire pump usually need pump to very high distance with water when work; Therefore often is in high pressure conditions in the pump chamber and acts on the machine shaft that is connected driving with fire pump, and the existing machine shaft output that is used to drive the motor of fire pump all is to hold with electric motor end cap through single shaft to be connected that the contact-making surface between bearing and the machine shaft is little; The frictional force that unit are is born is big; Not only frictional dissipation is big, and machine shaft ruptures easily, has had a strong impact on the useful life of motor.
Summary of the invention
The purpose of the utility model is to provide a kind of efficient constant current fire water pump motor, and it is through increasing the contact area of bearing and machine shaft, and the problem that machine shaft ruptures easily when having solved fire pump pump chamber high pressure has in the past prolonged useful life of motor.
The purpose of the utility model realizes through following technical scheme: a kind of efficient constant current fire water pump motor; It comprises electric machine casing, machine shaft, front end housing and rear end cap; The output of machine shaft stretches out front end housing and is connected driving with fire pump; It is characterized in that: be connected through a pair of duplex bearing rotational support of arranging vertically between machine shaft and the front end housing, the rear side of front end housing is provided with the bearing saddle bore that is used for installing duplex bearing.
Compared to prior art, the advantage of the utility model is: the utility model is through increasing the contact area of bearing and machine shaft, and the problem that machine shaft ruptures easily when having solved fire pump pump chamber high pressure has in the past prolonged useful life of motor.
