The leakage at the bottom of the feed mixer is a common problem in the mixer. How to solve the problem in the face of the mixer failure?
1. Check if the seal is damaged;
2. Check if the cylinder linkage device is suitable;
3. Check if the compressed air pressure is stable, especially when the temperature is low;
4. Check if the discharge door is deformed.
Sometimes the leakage of the valve at the bottom of the mixer is not necessarily a problem with the seal? I don't know if you noticed the capacity of the compressed air buffer tank? When they visited some domestic enterprises, they also encountered such problems. After the "diagnosis", it was found that the capacity of the buffer tank was too small. Since the compressed air system is shared, when the other equipment is in use, the air pressure is instantaneously lowered, and the air pressure at the bottom valve of the mixer is lowered to cause the shutdown to be unsatisfactory and the leakage is caused. Later, the capacity of the buffer gas tank was enlarged, and the phenomenon of leakage of the material disappeared.
In addition to this, there is a fault that the mixer door cannot be closed in place, and an external force must be artificially applied to the cylinder push rod to close the position. Many of the reasons are that the four-bar linkage of the hybrid door does not reach the self-locking position, and the closed state of the entire discharge door is completely maintained by the thrust of the cylinder. The paddle of the mixer always has a pressing effect on the discharge door during the operation. Since the compressed air itself has a certain compressibility, the discharge door is slightly closed, and the discharge door and the casing are During the formation of material backlog and continuous compaction, the discharge door is not closed tightly and leaks.
