The core purpose of this type of equipment is to produce acetylene gas on-site and on demand, providing fuel gas for gas welding and gas cutting operations.
Below is a detailed explanation of its specific purpose, working scenario, and characteristics:
1、 Core application: Provide acetylene gas for metal processing
Acetylene (C ₂ H ₂) can produce high-temperature flames of up to 3100 ° C when burned in oxygen, making it a very suitable fuel for metal welding and cutting. The main purpose of ASP-10 acetylene generator is to produce this gas, specifically for:
1） Gas welding:
Using acetylene flame to melt the base material and welding wire at high temperature to achieve the connection of metal components. Commonly used for welding thinner steel plates, non-ferrous metals (such as copper and aluminum) and their alloys, as well as welding repairs on cast iron.
2） Gas cutting:
This is the most important and common use. The acetylene flame first preheats the metal to its ignition point, and then introduces a high-pressure oxygen flow to cause the metal to burn vigorously (oxidize) in oxygen and blow away the slag, thereby cutting thick steel plates, steel ingots, etc. into the desired shape. It is widely used in shipbuilding, steel structure, mechanical maintenance and other fields.
3）Local heating:
Using a welding torch to locally heat metal workpieces for correction, heat treatment, or preheating to prevent welding cracks.
2、 Main application scenarios
The characteristic of this generator is “mobile” or “semi fixed” production, so it is suitable for:
1) In situations where there is no pipeline acetylene gas source, such as construction sites, field construction sites, equipment installation sites, ship repair plants, and outdoor areas of large factories.
2) In situations where gas consumption is high but it is inconvenient to use acetylene cylinders: for example, in some large workshops or projects, using multiple generators for centralized gas supply may be more economical and convenient than managing a large number of acetylene cylinders.
3) Emergency maintenance: It can be quickly deployed in case of sudden equipment failure requiring on-site cutting or welding.
3、 Introduction to Working Principle
The ASP-10 type belongs to the “calcium carbide water inlet” medium voltage generator. The workflow is as follows:
1. Feeding: Load calcium carbide (CaC ₂) into the calcium carbide basket of the generator.
2. Reaction: Calcium carbide comes into contact with water in the generator water tank and undergoes a chemical reaction: CaC ₂+2H ₂ O → C ₂ H ₂ ↑+Ca (OH) ₂
3. Storage and output: The generated acetylene gas is stored in the gas chamber of the generator and automatically maintained at a certain pressure (usually medium pressure, such as 0.045-0.1 MPa), and then transported through pipelines to the welding and cutting torch for use.
4. Slag discharge: The reaction byproduct calcium hydroxide (hydrated lime) slurry needs to be cleaned regularly.
Summary
The ASP-10 acetylene generator (or domestically produced 10m ³/h medium pressure acetylene generator) is an industrial equipment used for on-site production of acetylene gas. Its main purpose is to provide stable and economical fuel gas for metal gas welding, gas cutting, and heating processes. It is suitable for industrial applications that lack pipeline gas sources, require mobile operations, or require large quantities.
