What are the precautions for the use of wet sand blasting machine?
Casting cleaning is a necessary process in any foundry. Therefore, casting cleaning machine is particularly important in industrial production. The type of casting, such as size, shape, weight, production speed and production capacity requirements, will affect the choice of shot blasting machine. In addition, downstream production, such as the opinions of casting users, will also affect the foundry's choice of shot blasting machine. Here are some problems that should be paid attention to in the processing of wet sand blasting machine.
1. Precautions for wet sandblasting machine processing
In the process of processing and construction of wet sand blasting machine, the pressure of air compressor in the construction process shall not be less than 8Mpa to ensure the sand blasting adhesion. When the wet sandblasting machine is working, the air pressure in the working area shall not exceed the allowable pressure of the sandblasting machine accessories (usually within 6 atmospheres).
2. Dust pollution has become a major problem of air pollution in the 21st century
It is a direct threat to people's lives, especially in the dust polluted environment, will cause a variety of cardiovascular and respiratory diseases. Due to the needs of production and processing, the application of wet sand blasting machine has become the product of enterprise processing. Now, more and more enterprises buy the accessories of sand blasting machine. The accessories of sand blasting machine are used in more and more industries. The enterprise should consider all factors comprehensively and find a reasonable solution for the asset loss which can not be ignored.
3, sand blasting technology is mainly used in the need of plastering and brickwork. It is not only a kind of interface material with excellent performance, but also a kind of beautiful and generous reserved decorative surface.
Temperature is a factor to be considered when choosing casting cleaners. The ideal temperature for casting shot blasting is close to the ambient temperature, however, cooling times vary from foundry to foundry, so the temperature at which casting enters the shot blasting chamber varies greatly. Therefore, in the design of the cleaning machine, the user should consider the possible temperature required for production. It is assumed that the customer needs to clean high temperature castings, and the cleaner designed by the sandblaster meets these requirements to reduce future maintenance, downtime and other problems, including operational safety hazards. High temperature operation also requires special maintenance of the cleaning machine. High temperature components, high temperature machines and high temperature abrasives pose challenges to the maintenance and operation safety of cleaning machines. In this production condition, the lubrication of the bearing of the cleaning machine, the design of the conveyor belt, the composition of the wearing parts, the ventilation and control system often need to be replaced. Chains and other non-combustible materials replace rubber seals, curtains and tracks.
Some precautions should be avoided with sandblasters. Users can choose a wet sand blaster. Wet sand blasters have become very popular in recent years. The principle is to mix sand and water so that no dust is generated during operation. This is an environmentally friendly sand blasting machine.
