Abstract
The utility model relates to the technical field of water pumps, particularly to a novel high-speed multistage pump rotor, which is characterized by including a rear cover plate, blades, a front cover plate, an impeller ring, a shaft sleeve, a shaft shoulder, a coupler, a wheel hub, a flat key, an impeller and a shaft 1, wherein as the flat key is arranged on the shaft and clamped in the impeller, the novel high-speed multistage pump rotor does not require welding and can be formed once for all; the shaft sleeve on the shaft can prevent the shaft from being heated; and as the novel high-speed multistage pump rotor adopts stainless steel materials, the pump body has the effects of vibration reduction and water quality polluting avoidance.
Description
Technical field
The utility model relates to the pump technology field, especially a kind of novel high speed multistage pump rotor.
Background technique
Traditional water supply equipment is based on MODEL VERTICAL MULTISTAGE PUMP, and the multistage pump rotor is the cast member of gray cast iron material substantially, and this gray iron class cast member very easily gets rusty, and pollutes resident's water quality,
Summary of the invention
For addressing the above problem, the utility model provides a kind of novel high speed multistage pump rotor, overcome the problem that exists in production of splined shaft type stainless steel punching press pump and the use, the utility model combines prototype with existing punching press pump, learn from other's strong points to offset one's weaknesses, the flat key transmission is adopted in the transmission of cancellation splined shaft, innovates on the basis of succession.Described a kind of novel high speed multistage pump rotor, it is characterized in that, comprise: back shroud 1, blade 2, front shroud 3, choma 4, axle sleeve 5, the shaft shoulder 6, coupling 7, wheel hub 8, flat key 9, impeller 10, axle 11, described a kind of novel high speed multistage pump rotor, on axle 11, be provided with flat key 9, be used to be stuck in impeller 10, need not weld, can once-through.Described a kind of novel high speed multistage pump rotor is provided with axle sleeve 5 on axle 11, avoid axle 11 heatings, and described a kind of novel high speed multistage pump rotor all adopts stainless steel material.
The beneficial effects of the utility model are: 1. reduce the pump housing and shake, cause the damage of parts, prolong the service time of pump; 2. change pump performance, improved the efficient and the stability of pump; 3. owing to adopt stainless steel material, not polluted water.
