Abstract
The utility model discloses an industrial sewing machine oil pump which comprises a pump body. A sleeve is arranged in a first cavity of the pump body in a clamped mode, an impeller pillar of an impeller is arranged in the sleeve in a clamped mode, an impeller disc of the impeller is arranged in a second cavity of the pump body, and an end portion of the impeller disc of the impeller is sealed and covered by an impeller pressing plate and a net cover in sequence. A plunger hole is formed in the side face of the first cavity of the pump body, a plunger and a spring are arranged in the plunger hole, the spring is sleeved with the plunger, and the plunger and the spring are fixed through a plunger screw. An installation plate is arranged on an end portion of the pump body, the impeller pressing plate and the net cover are formed through integral injection molding, a groove is formed in the impeller pressing plate, and the groove is meshed with the impeller disc of the impeller in size. Due to the fact that the impeller pressing plate and the net cover are made through integral injection molding, the fastness of the impeller pressing plate which is made of engineering plastic materials can be improved. The impeller pressing plate and the net cover are made through integral injection molding, and the groove of the impeller pressing plate provides enough space for the rotation of the impeller disc of the impeller.
