What are the causes and solutions for the failure of the glass sandblasting machine

general fault refers to the phenomenon that the glass sandblasting machine loses or reduces its specified function. The glass mechanical equipment of the enterprise is equipped to meet the production process requirements or to complete the expected functions of the project. The function of the glass sandblasting machine reflects its value in the production activities and the degree of guarantee for the production. The failure of glass sandblasting machine will seriously affect the quantity of enterprise products

I. common causes and solutions for non sanding of glass sand blasting machine

1 Too much sand is added

which causes plugging and cannot be pressurized. Solution: the amount of sand should be appropriate, not too much. Spray gun plugging. Solution: after the structural characteristics of the manual broaching machine for sample notch are stopped, the nozzle shall be replaced every 6 months to see if there is any foreign matter. If there is any foreign matter, it is OK as long as the foreign matter is cleaned up

2. Sand pipe plugging

solution: after the gas is stopped, remove the nozzle, dry the sand blasting machine, and blow out the foreign matters with high-pressure gas. If there is no effect, the pipe has to be removed for cleaning or replacement

3. Wet sand

solution: clean the spray gun nozzle, dry and filter the sand. No filtration, causing large foreign matters or uneven sand particles to enter the sand valve. Solution: open all sand regulating valves and remove foreign matters or caked sand materials with strong pressure air. If this is not possible, the sand can only be discharged to the melting point of 3652 ⑶ 687 ℃ and added after re filtration. Too little sand. Solution: turn off the sand blasting machine and air source, and add sand

4. How to keep the glass sandblasting machine damp

the equipment should be placed in a factory with good ventilation and daylighting. It is best to install a sponge for dust removal and moisture absorption on the cooling hole of the equipment, and the sponge should be changed frequently. The equipment can be waterproofed. For example, the compression test process of low carbon steel and cast iron by testing machines such as spraying, impregnation and potting can enhance the moisture-proof function of the equipment. Selecting electronic components and materials with low hygroscopicity can avoid equipment moisture to the greatest extent. If the equipment is not used frequently, it should be placed in a dry place with desiccant and covered with a protective cover. In case of wet seasons such as plum rain season, color changing silica gel desiccant can be used, and the desiccant should be changed frequently. The equipment shall be cleaned to ensure the cleanness of the equipment and its working environment

II. Fault analysis of glass sandblasting machine

during the operation of the full-automatic glass sandblasting machine, its internal parts have to bear a variety of effects such as stress, heat, friction and wear. With the growth of service time, its operating state is constantly changing, and some performance will gradually degrade, resulting in the failure of parts (components). This is the main reason for the failure of the glass sandblasting machine. Therefore, studying the failure mechanism of parts (components) and identifying the failure mode is the main task of ensuring the diagnosis, as well as laying the information foundation for fault diagnosis, so as to finally achieve the goal of reducing the life cycle cost of the equipment; Fault analysis (failure analysis) is the main component of diagnosis theory

the above is the related content about the glass sandblasting machine shared with you. I hope that through the above content, you can have a further understanding of the glass sandblasting machine products
