Abstract
The utility model discloses a pump shaft of a sewage pump. An anti-corrosion shaft sleeve is arranged between a pump shaft body and a bearing. The shaft sleeve is welded with the pump shaft body. The thickness of the anti-corrosion shaft sleeve is 1-3mm. The pump shaft of the sewage pump is simple in structure. When the pump shaft is used, only a stainless steel welding rod needs to be laid flat on a carbon steel pump shaft which is 2mm deep after being turned, a lathe is used for turning and polishing the carbon steel pump shaft, so that the thickness of the carbon steel pump shaft is kept consistent with that of an original carbon steel pump shaft, as a result, the stainless steel welding rod forms the anti-corrosion shaft sleeve on the carbon steel pump shaft. Therefore, the phenomena that the pump shaft is not sealed tightly by a seal ring and the pump shaft is fractured due to the fact that the carbon steel pump shaft is corroded by acid materials in water and sludge are avoided.
Description
Technical field
The utility model relates to a kind of pump shaft, relates in particular to a kind of sewage pump pump shaft.
Background technique
Sewage pump is for the control sludge back flow quantity in the sewage treatment process, to guarantee the quality of activated sludge.The pump shaft of sewage pump is used for rotary blade, and mostly being is to be made by carbon steel.Because contain the more mordant acidic materials of being with in water and the mud, Long contact time easily causes the surface etching of carbon steel pump shaft serious, even carbon steel pump shaft phenomenon of rupture occurs.Carbon steel pump shaft after the corrosion is in operation and wear phenomenon can occur, thereby causes the damage of seal ring, has affected the normal operation of the pump housing, has increased repair density and maintenance expenses.
The model utility content
The purpose of this utility model provides a kind of a kind of sewage pump pump shaft that can prevent that the sewage pump pump shaft is corroded.
The utility model adopts following technical proposals:
A kind of sewage pump pump shaft, described pump shaft surface is provided with an anticorrosion axle sleeve, and described axle sleeve and pump shaft are welding.
The thickness of described anticorrosion axle sleeve is 1-3mm.
Described anticorrosion axle sleeve is that stainless steel electrode is welded.
The utility model is simple in structure, only need tile with the dark carbon steel pump shaft of the 2mm of stainless steel electrode after turning during use; With lathe the carbon steel pump shaft is carried out the turning polishing, carbon steel pump shaft thickness and former carbon steel pump shaft are consistent, so just form an anticorrosion axle sleeve by stainless steel electrode at the carbon steel pump shaft, thereby avoided the carbon steel pump shaft because the seal ring that the acidic materials corrosion in water quality and the mud causes is poorly sealed and the pump shaft phenomenon of rupture.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
As shown in Figure 1, a kind of sewage pump pump shaft is provided with anticorrosion axle sleeve 2 between described carbon steel pump shaft 4 and the bearing 1, and described anticorrosion axle sleeve 2 is welding with carbon steel pump shaft 4.The thickness of described anticorrosion axle sleeve 2 is 1-3mm.The carbon steel pump shaft 4 of sewage pump is that carbon steel is made, and tiles with stainless steel on carbon steel pump shaft 4 surfaces, can prevent that acidic materials in sealing and the mud are to the corrosion of carbon steel pump shaft, the generation of stopping wear phenomenon.The described anticorrosion axle sleeve 2 of the present embodiment is for stainless steel electrode is welded, with dark carbon steel pump shaft 4 tilings of the 2mm of stainless steel electrode after turning; With lathe carbon steel pump shaft 4 is carried out the turning polishing, carbon steel pump shaft 4 diameters and former carbon steel pump shaft are consistent, make so simple and easy, with low cost.Also can use other anticorrosion axle sleeve directly to be nested on the sewage pump pump shaft 4 and realize anticorrosion ability.
The utility model makes the antiseptic property of the carbon steel pump shaft of sewage pump obtain very large reinforcement, has avoided carbon steel pump shaft 4 because seal ring 3 poorly sealed and carbon steel pump shaft 4 phenomenon of ruptures that the acidic materials corrosion in water quality and the mud causes.
After the utility model carries out preservative treatment by the carbon steel pump shaft to sewage pump, the acid resistance corrosion of pump shaft strengthens, and behind the sewage pump long-play, the surface does not have corrosion phenomenon, the harmless phenomenon of seal ring, guarantee the normal operation of sewage treatment operation, reduced maintenance cost.
