Abstract

The invention relates to a small single-stage water-ring vacuum pump, which includes a pump cover, a pump body, an impeller, a mechanical seal, a bearing support and a motor member. One end of the bearing support is firm-jointed with the motor by a bolt and the other end of the bearing support is firm-jointed with the pump body by a bolt. On the bearing support is mounted a bearing, which is sleeved on the mainshaft of the motor. The impeller and the mechanical seal in the pump body are direct mounted on the mainshaft of the motor.

Description

[technical field] [0001] The invention relates to the technical field of water ring vacuum pumps, in particular to a small horizontal single-stage single-suction ring vacuum pump. [Background technique] [0002] Existing single-stage single-suction ring vacuum pumps are generally water ring vacuum pumps in which the pump and the motor main shaft are connected together through a shaft coupling. This kind of water ring vacuum pump has many disadvantages: since the pump and the motor are connected through a coupling, its structure is not compact, the floor space is large, and it is difficult to ensure that the pump shaft is completely concentric. In addition, there are disadvantages such as unreliable operation, short service life, large vibration amplitude, and large noise. [Content of the invention] [0003] The purpose of the present invention is to solve the above-mentioned deficiencies and provide a small single-stage single-suction ring vacuum pump. The machine-pump c...
