Water blasting equipment Sand pipe It is a vulnerable part of the sandblasting machine. In order not to affect the work, general users need to purchase more sand pipes as spare parts. How can the spare sand pipes and the sand pipes being used on the sandblasting machine be maintained to extend the service life of the sand pipes to a greater extent?

1、 Maintenance of spare sand pipe:

1. In order to prevent the sand pipe of water sandblasting equipment from being compressed and deformed during storage, the stack height of hoses should not be too high, and generally should not exceed 1.5m; It is also required that the hoses are often "inverted stack" during storage, generally at least once a quarter

2. The warehouse for storing sand pipes of water sandblasting equipment and accessories of sandblasting machine shall be kept clean and ventilated, Sandblasting pipe When the relative temperature is below 80%, the temperature in the warehouse should be kept between - 15~+40 ° C, and the hose should be protected from direct sunlight, rain and snow

3. The sand pipe shall be stored in a loose state as far as possible. Generally, the sand blasting hose with an inner diameter of less than 76mm can be coiled for storage, but the inner diameter of the reel shall not be less than 15 times of the inner diameter of the sand blasting hose

4. When the sand pipe is stored, it shall not contact with acid, alkali, oil, organic solvent or other corrosive liquids and gases; And should be 1m away from the heat source

5. During the storage of the sand pipe of the water sandblasting equipment, it is strictly prohibited to stack heavy objects on the sandblasting pipe body to prevent external extrusion and damage

6. Generally, the storage period of sand pipe shall not exceed two years, and the sand pipe shall be put into storage first and used first to prevent the quality of sand blasting hose from being affected by too long storage

2、 Maintenance of sand pipe being used by sand blasting machine:

1、 Sand blasting machine It should be placed in a place away from sunlight to prevent the sand pipe and other accessories of the sand blasting machine from being damaged by the sun, which will accelerate the aging of the sand pipe

2. The pressure of the water sandblasting equipment should not be too high when it is working. Excessive pressure of the sandblasting machine will not only affect the sandblasting quality of the workpiece, but also accelerate the flow rate of the sand material when the pressure is too high, which will increase the impact force on the sand pipe and accelerate the wear of the sand pipe,

3. The sand pipe shall be hung as far as possible to avoid lying on the ground and being trampled by passers-by,

4. Do a good job of driving rats in the workshop to prevent the sand pipe from being broken by rats.
