Embodiment Construction

[0022] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0023] The present invention is a large-flow single-stage double-suction centrifugal slag flushing pump, the structure of which is as follows: figure 1 and figure 2 As shown, it includes an impeller 12, a pump shaft 13, and a pump casing 18. The pump shaft 13 passes through both sides of the pump casing 18. The impeller 12 is located in the pump casing 18 and is sleeved on the pump shaft 13 through the impeller key 11. The pump casing 18 It is a double volute structure, and the impeller 12 is provided with eight impeller blades 20 arranged symmetrically in the center, and a pointed impeller water outlet 21 is arranged between the two impeller blades 20 .

[0024] A shaft sleeve 7 is provided at the connection between the pump shaft 13 and the pump casing 18, and the outer circumference of the shaft sleeve 7 is sealed by an oil-stained asbes...

Abstract

The invention discloses a high-flow single-stage double-suction centrifugal slag flushing pump. The high-flow single-stage double-suction centrifugal slag flushing pump comprises an impeller, a pump shaft and a pump case. The pump shaft penetrates through the two sides of the pump case. The impeller is located in the pump case and connected to the pump shaft through an impeller key in a sleeving mode. The pump case is of a double-volute structure. The impeller is provided with eight impeller blades arranged in central symmetry, and a sharp-crested impeller water outlet is formed between the two of the impeller blades. Through the high-flow single-stage double-suction centrifugal slag flushing pump, the problems that a single-stage centrifugal slag flushing pump is large in size and small in flow and big-size and big-weight waste slag are not flushed cleanly in the prior art are solved.

Description

technical field [0001] The invention belongs to the technical field of double-suction pumps, and relates to a large-flow single-stage double-suction centrifugal slag flushing pump. Background technique [0002] Single-stage double-suction centrifugal slag flushing pumps are mostly used in thermal power plants and chemical industries. Most of the transported media are seawater and circulating water, and the outlet pressure is relatively high. [0003] The slag flushing pump is a liquid pump that provides pressure water for slag flushing to flush the waste 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 slag 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 eq...
