Liquid sandblasting machine process principle, application direction and environmental protection features
1. Principle of liquid sandblasting processThe liquid sandblasting machine has completely changed the traditional dry sandblasting method. It places the sand (abrasive) in water and uses a grinding fluid pump and compressed to spray the grinding fluid at high speed onto the workpiece to be processed, achieving the purpose of cleaning and polishing the surface of the parts. The liquid sandblasting process a high efficiency, low consumption of abrasive, can improve the surface finish of the workpiece, improve the surface strength, and fundamentally change the pollution to the environment. The is easy to install and does not need a separate workshop. It can be directly installed on the production line. Therefore, liquid sandblasting is superior to dry sandblasting.
2. Application of liquid sandblasting process
(1) Cleaning the rough surface of precision castings
(2) Removing oxide skin
(3) Removing smallrs from machining
(4) Cleaning dirt and rust
(5) Preparing for other surface treatment processes
(6) Polishing processing
(7) To obtain decorative surface without reflected light
(8) To improve the service performance of mechanical parts
After liquid sandblasting (shot peening), especially liquid shot peening, mechanical can significantly improve the fatigue strength and corrosion resistance of parts, such as springs, turbine blades, etc. After liquid sandblasting, surface defects on mechanical parts are easy to expose which helps in the inspection and flaw detection of part cracks.
3. Environmental protection features of liquid sandblasting
(1) It greatly improves the pollution of dust to the and the harm to the health of workers.
(2) It can be directly installed on the production line, saving production area and facilitating the turnover of workpieces.
(3)The working method is flexible, the process parameters are variable, and it can meet the requirements of polishing processing for parts with different materials and different precision.
(4 )During the working process, the abrasive is recycled and used, with low consumption.
(5) The main parts have a long service life and are easy to maintain
