Weighing coal feeder is used in circulating boiler pulverizing device of thermal power plant. It has the characteristics of pressure resistance, energy saving and environmental protection. It can realize the continuous and uniform coal transport in the fully closed, and can also be measured by furnace, which is the ideal coal consumption measuring equipment. Cleaning system is one of the important systems. How to clean the broken chain at work?

Weighing coal feeder cleaning chain broken chain first of all to clear the cause of the fault, only to "suit the case". There are three main reasons for this:

1. The force of the cleaning scraper on the chain is not uniform, and the material conveying size of the coal feeder equipment is relatively large. Due to the high adjustment of the material shaping door of the feed port, the thickness of the weighing material of the belt is too high.

2, the tensioner is improperly adjusted, the deviation on both sides is too large, the drive shaft and the driven shaft are not parallel, the drive sprocket can not be in the same plane, resulting in broken chain.

3, weighing coal feeder is likely to be active chain wheel bearings and driven sprocket of bow | bearing damage. The main and driven sprocket bearings of the cleaning chain in a general coal feeder cleaning system are spherical bearings with a seat. This bearing can be automatically aligning and changing the distance between the axes of the sprocket. The main and driven sprocket are in the same plane under the condition of good tensioner adjustment.
