Analysis on the Wear of Concrete Piston of truck mounted wet concrete spraying machine

Issue Time:2021-08-04
Concrete piston overall wear, partial wear, ablation wear, strain, and later maintenance methods.

Partial overall wear

1. Main features of overall wear

The radial wear of the lip part of the concrete piston of the concrete pump accessories is basically the same, and the wear marks are relatively uniform.

Second, the cause of the overall wear failure

Improper maintenance, poor lubrication, excessive load, quality problems of the concrete piston of the concrete pump accessories, such as excessive size or poor wear resistance of the material.

Three, overall wear and tear fault handling

1. Through the identification of the wear traces, it is confirmed that it is the overall wear of the concrete piston of the concrete pump accessories;

2. Check the washing room and cooling water to ensure that the washing room is clean;

3. Remove the dust ring to improve the lubrication and cooling of the concrete piston of the concrete pump accessories. You can add an appropriate amount of hydraulic oil for the concrete pump accessories to the washing room, and you can also replace the new guide ring to improve the lubrication;

4. Check the size of the concrete piston of the concrete pump fittings. Under normal circumstances, the lip of the concrete piston of the concrete pump fittings should be 4-5 mm larger than the diameter of the conveying cylinder;

5. Replace the concrete piston of the concrete pump parts made of other materials.
