Chemical mixer corrosion repair process, how to deal with cylinder failure?

In the chemical industry, some raw materials are used by mixing, and the mixing effect will directly affect the use of chemical raw materials. Now many places choose to use chemical mixers to mix chemical raw materials, but sometimes we find that the equipment is affected by raw materials and corrosion occurs. How should we repair it? Today, Xiaobian will introduce in detail "chemical mixer corrosion repair process, how to deal with cylinder failure? "

1、 Chemical mixer corrosion repair process

1. Sandblasting

Degreasing and derusting the parts of the treatment equipment, surface roughness, sandblasting above grade Sa2.5, surface roughness 40-50 μ M2. Clean the surface with anhydrous ethanol, keep it clean and dry without water or other media3. Before mixing treatment, roll to the bottom of the barrel without precipitation or mix evenly without precipitation;4. The anti-corrosion nano composite ceramic material is sprayed at the spraying place for several times to reach the required thickness5. The post curing coating was placed at room temperature for 1 week after coating;2、 Troubleshooting steps of chemical mixer cylinder1. The leakage inside and outside the cylinder is caused by eccentric installation of piston rod, insufficient lubricating oil, wear and damage of sealing ring and sealing ring, impurities in the cylinder and scar of piston rod. The middle position of the piston rod should be adjusted, the stability of the injector should be checked regularly, and the impurities in the cylinder should be eliminated in time.

2. The output force of the cylinder is not enough and the action is not smooth. The piston or piston rod is stuck, the lubrication is not good, the air supply is insufficient, or the cylinder has condensate and impurities. The middle position of the piston rod should be adjusted to check the stability of the oil spray nozzle and whether the air supply pipeline is blocked. The condensate and impurities in the cylinder should be removed in time.

3. The cushion effect of the cylinder is not good. Due to the damage of buffer ring or adjusting screw, the sealing ring and adjusting screw should be replaced.

4. The damage of piston rod and cylinder head is usually due to the eccentric installation of piston rod or the non working buffer mechanism. The middle position of piston rod should be adjusted in time, and the buffer seal ring or adjusting screw should be replaced.
