Problems solved by technology

In actual use, it is found that the oil seal on the side of the end cover of the bearing box often leaks lubricating oil, which on the one hand pollutes the environment on the device site; on the other hand, if the inspection is not timely, the gap between the oil seal and the shaft is due to wear The increase will cause more leakage of lubricating oil. When the oil level is lower than the rolling element at the bottom of the bearing, it will lead to poor lubrication of the bearing, so that the oil film cannot be formed between the relative moving parts in the bearing, and the parts in the bearing will contact each other and rub against each other. The heat of the bearing cannot be taken away quickly, the rolling elements of the bearing, the inner and outer rings and other parts are partially heated and expanded, and the gap is reduced, and the rolling elements of the bearing cannot perform relative motion between the inner and outer rings of the bearing, which will cause the bearing to lock up, burn out, and even cause the pump shaft, etc. Severe damage to vital components

The lubricant has excellent high-speed resistance, water resistance and corrosion resistance, can be used for high-speed and high-load sliding of a corrosion-resistant sliding bearing for a magnetic drive pump in contact with corrosive substances at high temperature and lubrication of a rolling bearing, and has excellent ageing resistance, water and steam resistance, acid and alkaline liquid resistance and the like.

Description

technical field [0001] The invention belongs to the technical field of lubricants, in particular to a preparation method of a corrosion-resistant sliding bearing lubricant for a magnetic pump. Background technique [0002] At present, the bearing lubrication of magnetic pump mainly adopts the method of lubricating oil bath lubrication. This method is simple to use and easy to maintain. The lubricating oil in the bearing box is brought up by the rotating bearing part or the oil ring hanging on the shaft, splashes it to various parts of the bearing for sufficient lubrication, and finally falls back into the oil tank to be taken up again. In this way, attention should be paid to the control of the oil quantity. Too little oil will cause insufficient lubrication of the bearing and premature wear and failure; too much oil will cause the bearing temperature to be too high. Generally, it is advisable that the lubricating oil level in the bearing box is slightly lower than the cen...
