Sandblasting hose Strict requirements for processing and production

Sand blasting hose is also a common kind of hose for transportation. The following section will introduce the specific precautions for sand blasting hose processing and production:

1. Wear protective equipment before processing sand blasting hose, and do not work with bare arms.

2. The air receiver, pressure gauge and safety valve shall be calibrated regularly. Dust is discharged from the air tank once every two weeks, and the filter in the sand tank is checked once a month.

3. Check whether the ventilation pipe and sandblasting machine door are sealed. The ventilation and dust removal equipment must be started five minutes before work. When the ventilation and dust removal equipment fails, the sandblasting machine is forbidden to work.

4. The compressed air valve shall be opened slowly, and the air pressure shall not exceed 0.8MPa.

5. The sand blasting particle size of the sand blasting hose shall be consistent with the work requirements, generally between No. 10 and No. 20, and the sand shall be kept dry.

6. When the sandblasting machine is working, irrelevant personnel are prohibited from approaching. When cleaning and adjusting the running parts, the machine should be stopped.

7. Do not use compressed air to blow dust on your body or make jokes.

8. After the work is completed, the ventilation and dust removal equipment should continue to run for five minutes and then be closed to discharge indoor dust and keep the site clean.

The sandblasting hose adopts high-quality rubberized cloth as the reinforcement layer, which has good flexibility and strong pressure bearing capacity; Sand blasting hose is made of special steel wire braid for copper plated hose, which bears 3-4 times of the working pressure of cloth clamping hose. It has the characteristics of high pressure resistance and excellent bending resistance. Sand blasting rubber hose is generally divided into light sand blasting rubber hose and heavy sand blasting rubber hose according to the working conditions and the loss of material particles to the conveying medium. The spiral steel wire will make it suitable for negative pressure environment.

Light sand blasting hose is usually used in the use environment such as ship sand blasting and quicksand operation; The common inner rubber is made of wear-resistant NBR (natural rubber) material, and the outer rubber is wrapped with composite rubber.

Heavy sandblasting hose is used for equipment sandblasting sand gravel, fine pebble, mud and other use environments, and sandblasting vacuum pipe.

    Sand blasting vacuum hose Spiral steel wire is embedded, and the general vacuum negative pressure can reach 0.9.
