Centrifugal water pump formed through spinning-stamping welding of steel plates

Abstract

The invention discloses a centrifugal water pump formed through spinning-stamping welding of steel plates. According to one assembling method, the steel plates are welded after being spun and stamped,so that the simple centrifugal water pump is formed. According to the other assembling method, the steel plates are welded after being spun and stamped, so that the centrifugal water pump provided with a well killing head is formed. By adoption of the centrifugal water pump based on the novel process, the defects of the prior art are overcome. The centrifugal water pump is formed by the steel plates which are spun and stamped and are then welded, so that all parts of the whole water pump do not need to be machined through a traditional casting process which can cause severe pollution; all thesteel plates forming the centrifugal water pump are welded after being spun and stamped, so that all the parts of the water pump are more durable and lighter; and the production speed is high, the quality is high, and the time, cost, strength and labor are saved at the same time.

Description

technical field [0001] The invention relates to a steel plate spinning, stamping and welding centrifugal water pump. Background technique [0002] At present, there are two types of centrifugal water pumps on the market. One is simple: it consists of a water inlet tap (including a check valve), a water delivery pipe, and a pump head. A centrifugal water pump. The other is to add a tee on the water inlet on a simple basis, and a centrifugal water pump with a kill head on the tee. [0003] Existing techniques are all foundry foundry pouring techniques, which require a large space and a large amount of labor when foundry. Melt iron needs to be melted during pouring, which will generate a lot of pollution. At the same time, the products produced not only have a high scrap rate but also semi-finished products, which require secondary processing. [0004] The current pump casing, bearing body casing, water inlet, water outlet, tee, and kill head are all cast and foundry casting...

AI Technical Summary

Problems solved by technology

[0003] The existing technology is foundry foundry pouring technology, this kind of technology needs a lot of space and a lot of labor when foundry

Molten iron is needed during pouring, which will generate a lot of pollution. At the same time, the products produced not only have a high scrap rate but also semi-finished products, which require secondary processing.

[0004] The current pump casing, bearing body casing, water inlet, water outlet, tee, and kill head are all cast and sand casting processes. The products produced are not only rough, but the casting process will also cause great pollution to the environment.

[0005] The impeller is the core of the centrifugal water pump. At present, the casting casting process is also used. This process is difficult to overcome the arc required by the blades on the impeller. The centrifugal force of the impeller rotation can only be used to pump water.
