Abstract

The invention discloses a high-power sewage pump impeller structure, and relates to the field of sewage pumps. The high-power sewage pump impeller structure comprises an outer shell. An oil seal shellis arranged at the top end in the outer shell, a rotary shaft is arranged at the top end of the oil seal shell, the rotary shaft penetrates through the oil seal shell and stretches into the outer shell, and a sealing mechanism is arranged at the position, on the outer side of the rotary shaft, in the oil seal shell. Through the arrangement of a filter net, a first fixing ring, a second fixing ring, the oil seal shell and fixing bolts, when a sewage pump needs to be cleaned, firstly, the sewage pump is taken out of sewage, the sewage pump is flushed with clean water, the filter net is detachedfrom the device, then the filter net is flushed, impurities attached to the filter net are flushed away, after flushing is completed, the filter net is mounted at the original position again, then lubricating oil in the oil seal shell is extracted, the multiple groups of fixing bolts are rotated, the oil seal shell is taken down from a water seal plate, and the sealing mechanism sleeving the outer side of the rotary shaft is washed and dried.

Description

technical field [0001] The invention relates to the field of sewage pumps, in particular to a high-power sewage pump impeller structure. Background technique [0002] The sewage pump is a kind of pump product that is connected with the pump and the motor, and submerges into the liquid to work at the same time. Compared with the general horizontal pump or vertical sewage pump, the sewage pump has a compact structure, a small footprint, convenient installation and maintenance, and large Sewage pumps are generally equipped with automatic coupling devices that can be installed automatically. Installation and maintenance are quite convenient. Sewage pumps are widely used in various fields. With the characteristics of slippery liquid, the sewage pump is widely used in mining, papermaking, printing and dyeing, environmental protection, oil refining, petroleum, chemical industry, farm, dyeing, wine making, food, fertilizer, coking plant, construction, marble factory, mud , quicksan...
