022020-01Can square diffuser be used as return air port? There are peAs for the horizontal supply of air supply diffusers, it should be arranged symmetrically or in quincunx shape. The distance between the center of the diffusers and the side wall should not be less than 1000mm. When the circular or square diffusers are arranged, the length width ratio of the corresponding air supply range (area) should not be greater than 1:1.5.

022020-01How to make the bearing clearance very small, but does not aThe clearance of rolling bearing is generally divided into original clearance, installation clearance and use clearance. The original clearance, also known as manufacturing clearance, is produced by the bearing manufacturer according to the requirements of national or industrial standards and different bearing types. The bearing clearance finally selected by the mechanism designer is also this clearance.

022020-01Introduction to cylindrical roller bearingThe cylindrical roller and raceway are linear contact bearings. The load capacity is large, mainly bearing radial load. The friction between the rolling body and the retaining edge of the ferrule is small, which is suitable for high-speed rotation. According to whether the ferrule has a flange, it can be divided into Nu, NJ, NUP, N, NF and other single row cylindrical roller bearings, NNU, NN and other double row cylindrical roler bearings. The bearing is a separable structure of inner ring and outer ring.

022020-01Some misunderstandings in judging the quality of rolling beaIn the process of selling rolling bearings, many customers said that as long as the surface of rolling bearings is bright, the quality is good, which is wrong. The surface of rolling bearing should be dark bright, which is caused by whether the steel used for rolling bearing is up to the standard and the grinding process and cutting fluid used, among which the former two are the main ones.

First, consider to solveOverheating is the biggest culprit of bearing failure, mainly because bearing heating is generally an alarm signal of abnormal operation of the machine, and failure to deal with it as soon as possible will cause chain reaction such as damage to the machine. Common causes of bearing heating include:
