Balanced and stable high-flow single-stage double-suction centrifugal ash flushing pump

Abstract

The invention discloses a balanced and stable high-flow single-stage double-suction centrifugal ash flushing pump. The pump comprises a pump body, a pump shaft and a coupling. A pump cover is connected to the pump body through double-end bolts. An impeller is arranged in the pump body. The impeller is connected to the middle portion of the pump shaft through an impeller key. A first bearing and asecond bearing are arranged in the positions, on the two sides of the outer portion of the pump body, of the pump shaft correspondingly. The coupling is connected to one end of the pump shaft througha key. The pump body is of a double-volute structure. The impeller is composed of six curved impeller blades which are spaced in a staggered mode. The defection angle of the impeller blades is 9 degrees to 12 degrees. Through the balanced and stable high-flow single-stage double-suction centrifugal ash flushing pump, the problems that an ash flushing pump of a single-volute structure is poor in stability and balance and the service life of the pump is affected in the prior art are solved.

Description

technical field [0001] The invention belongs to the technical field of ash washing pumps, and relates to a balanced and stable large-flow single-stage double-suction centrifugal ash washing pump. Background technique [0002] The ash flushing pump is a liquid pump that provides pressure water for ash or slag flushing to flush the ash and slag along the ash ditch to the ash slag pool. Generally, a single-stage centrifugal pump is used. As a kind of hydraulic slag removal equipment, the ash flushing pump is used to remove the slag discharged from the furnace cold ash hopper after fuel combustion, the fly ash falling from the flue ash hopper and the fine ash collected by the dust collector, and transport the ash to the gray yard. Environmental protection equipment has become an indispensable infrastructure in contemporary China's industrial development, and plays a vital role in protecting the environment and removing haze. Especially for thermal power plants, iron and steel...
