Any machine can’t be used without good maintenance, and the straw briquetting machine is no exception. In the process of using the straw briquetting machine, we often encounter the problem of parts rusting, which is mainly duo to the material of parts. Most parts are made of metal, so it is inevitable that they will rust. So, rust removal is very important when this problem occurs. Rust removal methods include:

First, dehydration. Use 95% industrial vaseline and 5% industrial paraffin to heat it. When there is no foam on the surface, put the wearing parts in and take them out after cooling.

Second, waxing. Put the dehydrated parts into a wax pot to be dipped in wax, and put the parts into continuously heated wax liquid to be dipped in wax, and then take them out quickly.

Third, packaging. Put the waxed parts in pre-cut wrapping paper, which should be made of tough paper, kraft paper for large gears and shafts, white paper or plastic paper for shaft sleeves and springs, etc.

Fourth, rust removal. Parts with low precision can be derusted with sandpaper and steel ball, and shafts or gears with high precision can be gently wiped with No. 00 fine sandpaper. Be careful not to leave scratches and reduce the precision of parts. For bearings with high precision, 15% anhydrous chromic acid, 8.5% acid and 76.5% water can be used to prepare acid solution, which is heated to about 90℃. The parts can be soaked in it for 40 minutes, then cleaned with clean water after being taken out, dipped in 10% sodium nitrite solution at room temperature for 15 minutes, and then cleaned with clean water. For general gears and shafts, soak them in 10% sulfuric acid solution at room temperature for 30 minutes, and then clean them with clean water until they are not red by blue test paper.

The maintenance of the accessories of straw briquetting machine is related to the service life of the briquetting machine. Regular maintenance of the accessories can also avoid the drastic increase of production cost caused by frequent replacement of the accessories, and improve the production efficiency. Besides the rust of the accessories, any other faults or problems of straw briquetting machine should be checked and repaired in time, so as to ensure the smooth progress of production and the stability of production benefits.
