Description
Technical field
The utility model relates to a kind of liquid sewage pump, belongs to field of mechanical technique.
Background technology
Dredge pump is a kind of Pump and Electromotor disjunctor, and slips into the pump series products of working under liquid simultaneously, and compared with general horizontal pump or vertical sump pump, dredge pump compact conformation, floor space are little. Installation and maintenance are convenient, and large-scale dredge pump is typically equipped with automatic lotus root locking device can carry out Auto-mounting, and it is quite convenient to install and keep in repair. Continuous operation time is long. Dredge pump is due to pump and motor coaxle, and axle is short, and rotatable parts are lightweight, and the load (radially) of therefore bearing on bearing is relatively little, and the life-span is more much longer than general pump. There is not the problem such as cavitation damage and water. Particularly, a bit bring very large convenience to operating personnel. Vibration noise is little, and electric machine temperature rise is low, environmentally safe.
Existing dredge pump has following weak point: 1) flow is little, affects transfer efficiency; 2) after axle uses a period of time, easily damage.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art part, and a kind of liquid sewage pump is provided.
Liquid sewage pump of the present utility model, comprise the threephase asynchronous machine (1) that is located at top, be located at the motor cabinet (6) of threephase asynchronous machine (1) below, be located at the shaft coupling (5) in motor cabinet (6), be connected in the upper axle bed (7) of shaft coupling (5) below, the upper bearing (metal) (13) being connected with upper axle bed (7), be connected in the pump shaft (15) of upper bearing (metal) (13) below, be connected in the lower bearing (16) of pump shaft (15) below, the lower axle bed (20) being connected with lower bearing (16), the pump cover (22) being connected with lower axle bed (20) and spiral case (26), be located at the impeller (27) in pump cover (22) below and spiral case (26) and be located at the base (33) below impeller (27), described upper axle bed (7) one sides are connected with drain pipe (37), outside described pump shaft (15), be provided with connecting tube (14), described threephase asynchronous (1) and upper bearing (metal) (13), pump shaft (15) and lower bearing (16) are coaxial.
Liquid sewage pump of the present utility model, has following technique effect: bearing and motor coaxle, to stablize, and long service life, reduces energy consumption.
