Introduction to the Main Structure and Working Principle of the Sandblasting Machine

The Main Structure of the Sand Blasting Machine: 1. General Composition A well-functioning dry sand blasting machine typically consists of six systems: the structural system, medium power system, pipeline system, dust removal system, control system, and auxiliary system. 2. Operating Principle The dry sand blasting machine with suction operates using compressed air as the power source. The high-speed airflow creates a negative pressure inside the nozzle, which draws the abrasive material through the sand pipeline. The abrasive is then inhaled and ejected through the nozzle to the surface being processed, achieving the desired finishing effect. In the suction-type dry sand blasting machine, compressed air serves as both the power source and the abrasive medium. Pressure Feed Dry Sand Blasting Machine 1. General Composition A complete pressure feed dry sand blasting unit generally consists of four systems: the pressure tank, medium power system, pipeline system, and control system. 2. Operating Principle The pressure feed dry sand blasting machine uses compressed air as the power source, and the working pressure is established within the pressure tank. This pressure pushes the abrasive material through the sand valve, into the pipeline, and then ejected through the nozzle to the surface being processed, achieving the desired finishing effect. In the pressure feed dry sand blasting machine, compressed air serves as both the power source and the abrasive medium. Liquid Sand Blasting Machine Compared to dry sand blasting machines, the liquid sand blasting machine's major feature is its excellent control over dust pollution during the sandblasting process, improving the working environment for sandblasting operations. 1. General Composition A complete liquid sand blasting machine typically consists of five systems: the structural system, medium power system, pipeline system, control system, and auxiliary system. 2. Operating Principle The liquid sand blasting machine uses a磨液 pump as the power source for supplying the abrasive medium. The pump sends a well-mixed abrasive slurry (a mixture of abrasive material and water) into the nozzle. Compressed air acts as the acceleration power for the abrasive medium, entering the nozzle through the pipeline. Inside the nozzle, the compressed air accelerates the abrasive medium and is ejected through the nozzle to the surface being processed, achieving the desired finishing effect. In the liquid sand blasting machine, the abrasive pump is the feeding power source, and the compressed air is the acceleration power source.
