How to judge the quality of conveyor idler in 30 seconds?

Belt conveyor system play an increasingly important role in modern industries, such as coal mines, power plants, ports, and automated packaging lines. All industrial areas have their presence, whether it is dusty factories and mines, or spotless modern pharmaceutical packaging production lines, or The chemical industry with harsh and corrosive environments is the environment that it has to face. The pressure of the core component of the conveyor idler must be conceivable. Therefore, the choice of high-quality conveyor idler will not affect the safety of the conveyor in the future. Failure and rotation are important, so how to judge high-quality conveyor idlers? You may foucs on following points:

1. Pay attention to the quality of the conveyor idler tube. A good conveyor idler special welded straight seam tube should have uniform wall thickness, no decorative pits on the inside and outside, no groove marks or convex marks on the rear welding seam, and no defects such as misaligned cracks on the welding surface. .

2. Sealing system. The seal must be assembled strictly. The seal cover outside the seal should not be out of concentricity with the bearing seat, and there will be a larger gap on one side, so that external dust and water can easily enter the inside of the conveyor idler seal.

3. The rotation resistance of the conveyor idler, the bearing and seal of the high-quality conveyor idler are put into a certain amount of lithium-based grease when assembling, so all the rotation resistance of the conveyor idler during the experimental rotation comes from the adhesion of the lithium-based grease in the bearing When the idler is in normal use, there will be more grease to lubricate the bearing to extend its life, while inferior idler is assembled to reduce its cost, and less or no lithium-based grease is placed in the process of using the idler. When it is fully lubricated, the life of the conveyor idler is greatly reduced.

4. radial runout (TIR)

Let the conveyor idler rotate in place. Observe the radial runout (TIR) of the idler. Excessive radial runout will cause the conveyor belt to vibrate, increase the running resistance of the conveyor belt, and consume more power. Therefore, this is an important technical indicator of the roller.

5. Welding quanlity

Observe whether the welding track of the conveyor idler is complete and smooth. If the welding of low quality will cause the idler to crack during operation, it will seriously affect the sealing performance of the idler and reduce the operating life of the conveyor idler.
