How long is the abnormal treatment and service life of hard alloy glasses and cutting rings?
Concrete pump trucks can easily cause pipe blockage during transportation. When the hard alloy glasses and cutting ring are worn out for a certain period of time, there will be a certain gap, causing water, cement slurry, etc. in the concrete to spray out from the middle of the gap between the glasses and cutting ring during pumping. When the gap is large, it is easy to cause pipe blockage. When pumping water, water will spray out of the hopper from the gap between the eyeglass plate and the cutting ring, resembling a fountain.
The service life of hard alloy glasses is about 50000 cubic meters, and under normal cubic meters, the service life is about half a year. The cutting ring is about 25000 cubic meters, and under normal cubic meters, the service life is about three months.
Therefore, after the concrete pump has been working for a period of time, the direction of the cutting ring should be adjusted in a timely manner, the irregular nut should be tightened, and the gap between the eyeglass plate and the cutting ring should be reduced, which is beneficial for extending the service life of the eyeglass plate and the cutting ring.
