Problems solved by technology

The cast iron casing has a single rotation angle, the cost of the casting model is high, and the machining volume of the casting is large
The installation angle of the blades of the impeller is small, and the blade profile is curved back and conical arc, which is easy to adhere and bond, causing the rotor to be unbalanced, requiring frequent maintenance, and affecting the user's process flow

Embodiment Construction

[0006] In the following, the present invention will be further described in conjunction with the embodiments.

[0007] Both the casing and the air intake chamber adopt the steel plate welding structure. The inlet of the casing is 270 degrees to the left and the outlet is 180 degrees to the left. Other angles can also be made as needed to meet the pipeline layout under various working conditions. Annealing for one time, roughing, and then annealing for the second time for the casing for finishing; when the facet of the casing is not bolted, check with a 0.04mm feeler gauge and make an airtight test; the blade is made of high-temperature alloy steel plate Material, and planed at the welding place, the blade surface is sprayed with alloy powder, the spraying thickness is 1mm, and the surface hardness reaches HRC58-62; the main shaft is made of high-strength alloy steel for integral forging.

Abstract

The invention relates to the field of single-suction wear-resistant anti-corrosion gas-blowing engines, in particular to a new process for preparing a single-suction wear-resistant anti-corrosion gas-blowing engine. The technical scheme of the invention is as follows: a shell and an intake chamber are respectively in a steel plate welding structure; the inlet of the shell is 270 degrees on the left, and the outlet is 180 degrees on the left; after the shell is welded, primary annealing is carried out on the shell for rough machining, and secondary annealing is carried out on the shell for finish machining; blades are made of high-temperature alloy steel plates, the welding is polished, alloy powder is sprayed on the faces of the blades, and the spraying thickness is 1mm; and the main shaft is integrally forged from high-strength alloy steel. Due to the adoption of the technical scheme, under the driving action of a prime motor, the pressure, speed and temperature of the gas after passing through an impeller are raised, thereby lowering the cost of the complete machine and enhancing the quality of the product.

Description

Technical field [0001] The invention relates to the field of single-suction wear-resistant and anticorrosive gas blowers, and is a new process for preparing single-suction wear-resistant and anticorrosive gas blowers. Background technique [0002] At present, domestic wear-resistant and anticorrosive gas blowers are mainly used for less than 50 tons, and the working conditions are narrow. The cast iron casing has a single rotation angle, the cost of the casting model is high, and the machining volume of the casting is large. The blades of the impeller have a small installation angle, and the blade profile is in a back-bent cone arc, which is easy to adhere to and cause the rotor to be unbalanced, requiring frequent maintenance, and affecting the user's process flow. Summary of the invention [0003] The purpose of the present invention is that both the casing and the air inlet chamber adopt the steel plate welding structure, the blade adopts high-temperature alloy steel plate mat...
