1. Working principle:
This machine adopts pressure-feeding sand blasting (shot blasting) structure, which uses compressed air to flow at high speed in the high-pressure tank to form a high-pressure effect, and the sand in the high-pressure tank is sprayed out through the sand pipe, and then sprayed to the workpiece at high speed with the compressed airflow Surface, to achieve the purpose of sandblasting.1.1The advantages of sandblasting are:
It can replace the pickling and phosphating process, without the problem of sewage charges. Quick sandblasting and rust removal can remove welding slag, burrs and flash while changing the surface roughness. High efficiency, low cost, and good quality are unmatched by traditional chemistry and manual rust removal. After sandblasting, the paint quality is good and the coating life is long, which is the universal process method currently used internationally.
1.2 In order to adopt sandblasting and rust removal technology, the following three problems should be solved:
1.21 Sand can be automatically recycled many times to reduce costs.
1.22The sandblasted dust should be collected to meet the emission requirements and not cause pollution.
1.23Low energy consumption, low-cost operation, with good economy.
Therefore, any factory will consider these issues when choosing to build a sandblasting workshop or choose a sandblasting process.
2. Product features：
2.1Press-in working mode, high working pressure (0.5-0.8MPa), strong jetting force and high efficiency.2.2Fast and sensitive start-up.
2.3Wheel structure, easy to move.
2.4Small size, easy to add sand, suitable for single operation.
2.5Adopt American advanced sand valve structure, which can accurately adjust the size of sand and air pressure.
2.6Adopt standardized pressure vessel manufacturing standards, comply with industry standards, and be safe and reliable.
2.7 Equipped with wear-resistant sandblasting pipe and nozzle to ensure normal operation for a long time.
2.8Simple operation, easy to repair and maintain, and low cost.
A. Used for cleaning leather, molds, glass, stone carvings, ship building, bridges, mines, machinery, petroleum pipelines, water conservancy projects, port construction, etc. Rust removal, spray processing, rough surfaces of workpieces, oxide scales, and burrs. It can be used for spraying and electroplating pretreatment procedures to improve the adhesion of the coating (plating) layer and all surface treatments.
