The most important part of the decanter centrifuge is the transmission part, and the bearing is an important part of the transmission part. Generally, experienced centrifuge purchasers will ask the manufacturer a series of questions about the bearing when purchasing the centrifuge.
Here we discuss the issue of bear
- It may be due to overload or overload;
- It may be due to heat generated by mechanical friction;
But the main problem is whether the bearing is authentic or not. Some users buy low-priced bearings for low prices, which will cause the bearings to become hot and hot, causing the bearings to burn out.
Therefore, first emphasize the need to purchase authentic bearings.
The decanter centrifuge is a high-speed chemical and pharmaceutical equipment. High-speed bearings require good bearings. High-quality and authentic bearings can ensure the long-term normal operation of the centrifuge, and the service life can reach more than 10 years.
Second, we must pay attention to adhere to the mechanical lubrication and choose high-quality high-temperature lithium-based grease. The quality of the lithium-based grease is another main reason for bearing heat.
In addition, you must check with your detailed situation. Assuming that mechanical friction will be accompanied by noise, mechanical parts will have obvious wear, and the bearing will be loose, then it should be a bearing problem, and the bearing needs to be replaced.
Third, whether the concentricity of the centrifuge spindle and the bearing seat is accurate during the machining process. Under normal circumstances, people do not pay much attention to the concentricity. The high concentricity of the spindle tends to cause bearing generating heat.
Fourth, in the machining process of the spindle and the bearing seat, t tolerance is not in place, and the clearance between the bearing inner ring (outer ring) and the ball (column) is too small.
