The purpose of the utility model realizes through following technical scheme: a kind of efficient constant current fire pump is used deluge proof motor; It comprises casing and is fixedly arranged on the outer terminal box of casing that it is characterized in that: said terminal box comprises box body that is provided with nipple orifice and the cable waterproof joint that is connected with nipple orifice; Said cable waterproof joint comprises track bolt, collar nut and the seal cartridge that is provided with coaxial through-hole; Said track bolt comprise the front end spiral shell head that is connected with the internal thread hole of being located at the collar nut rear end, coaxial be fixedly arranged on front end spiral shell head rear end and and the rear end spiral shell head that is connected of nipple orifice and be located at front end spiral shell head and rear end spiral shell head between flange; The rear end of said seal cartridge is placed in the through hole in the front end spiral shell head body, and the front end periphery wall of seal cartridge is pre-small post-large conical butt; The front end of said front end spiral shell head also is fixedly connected with the flexible locking piece that multi-disc is posted by the front end periphery wall of seal cartridge, and the front end internal perisporium of said collar nut is provided with and is used for cooperating with flexible locking piece the locking roof pressure portion of collapsed seal lining leading section.
The method for using of the utility model is following: the releasable joint nut; With cable pass the cable waterproof joint get into carry out corresponding wiring in the terminal box and connect after, lock-on connection nut, locking roof pressure portion roof pressure flexible locking piece; Make seal cartridge hold cable tightly, thereby play sealing function.
The utility model has also carried out improving:
Said casing front and back end portion is provided with the end cap that is fixedly connected with casing respectively, and the cooperation place between said end cap and the casing is provided with the O RunddichtringO.Fire-fighting also comprises with waterproof machine to be located in the casing and the front and back end is arranged in the rotating shaft on the front and rear cover respectively, and the outside portion of each end cap and the cooperation place of rotating shaft are arranged with axle and use sealing ring.Improve the integral waterproofing performance of motor so greatly.
Compared to prior art, the advantage of the utility model is:
(1) through the utilization of cable waterproof joint, can guarantee the sealing of cable joint, anti-sealing gets into motor internal via cable joint and causes damage.
(2), improve the integral waterproofing performance of motor greatly through O RunddichtringO and the setting of axle with sealing ring.
