Common questions about water-based extreme pressure lubricants?
August 06, 2022
Water-based extreme pressure lubricants are also one of the petroleum products, commonly known as butter. It is a kind of solid or semi-fluid lubricant made from lubricating oil (including synthetic lubricating oil) by adding thickener and petroleum product additives. It has good lubricity, plasticity and certain adhesion. Many friends have encountered a lot of questions in the use of water-based extreme pressure lubricants. The following explains the common questions about these water-based extreme pressure lubricants.
Water based extreme pressure lubricant Question 1: What is the appropriate filling amount of water-based extreme pressure lubricant in the bearing? The filling amount of the water-based extreme pressure lubricant has a great influence on the bearing operation and the consumption of the water-based extreme pressure lubricant. Excessive filling of the water-based extreme pressure lubricant in the bearing will increase the bearing friction torque, cause the bearing temperature to rise too high, and lead to the leakage of the water-based extreme pressure lubricant. On the contrary, insufficient or too little filling may cause bearing dry friction. and damage the bearing. Excessive filling of grease will also cause excess water-based extreme pressure lubricant to leak from lubricating parts, which will have adverse effects on mechanical operation. There are various empirical formulas for calculating the appropriate filling amount of water-based extreme pressure lubricant. Generally speaking, the filling amount of sealed bearings and water-based extreme pressure lubricants is 1/3-2/3 of the inner cavity of the bearing. The temperature rises when the bearing is filled with water-based extreme pressure lubricant. Question 2: Why should water-based extreme pressure lubricants be supplemented and replaced in use? Water-based extreme pressure lubricants will be oxidized and deteriorated during use, the Base Oil will be reduced, and sometimes the lubricating effect will be lost due to the mixing of external impurities, or it will be gradually consumed during the working process. Therefore, water-based extreme pressure lubricants must be regularly replenished and replaced to meet the lubrication requirements of components. The period of bearing relubrication varies according to the size of the bearing, relative speed of motion, load, operating temperature and the sealing effect of the bearing. Most of the bearing manufacturers use the dn value as the calculation standard.
