Analysis of complete system structure of pressure blasting machine
Pressure sand blasting machine A complete suction dry blasting machine is generally composed of six systems, namely the structural system, medium power system, piping system, dust removal system, control system and auxiliary system.
Working principle The suction dry blasting machine is driven by compressed air, and the negative pressure formed in the spray gun through the high-speed movement of the airflow. The abrasive is sucked into the spray gun through the sand conveying pipe and ejected through the nozzle. Processing purpose. In the suction-type dry blasting machine, compressed air is both the supply power and the acceleration power of the jet.
1. High efficiency: A frozen blasting machine can process the blasting amount equivalent to 80-100 skilled workers every day.
2. Low cost: The use of frozen blasting machines can greatly reduce production costs, such as saving blasting, management, raw material, mold costs, and plant floor space.
3. High quality: The frozen blasting machine can perfectly remove the burr of the product according to the production requirements, and can handle some special structures that cannot be processed manually. It does not save energy for the pressure blasting machine. At present, the environmentally-friendly sand blasting machine consumes 0.8 cubic meters of flow per minute per gun. The previous sand blasting machine used 1 cubic meter of flow per minute per gas source.
Pressure sand blasting machine sealing system The environmental protection type sand blasting machine has also greatly improved the sealing effect. Previous sand blasting machines generally used some beading and rubber strips to improve the sealing of some door seams of sand blasting equipment. The environmental protection type sand blasting machine now uses an imported rubber to increase the sealing performance. The sealing performance of the film is 5 times that of the rubber strip.
