2. The bearing is a component that is sleeved on the pump shaft of the multistage pump to support the pump shaft. There are two types of rolling bearings and sliding bearings. Rolling bearings use tallow as a lubricant to refuel properly. Generally 2/3～3/4 of the volume is too much to generate heat, too little and there is noise and heat! The sliding bearing uses transparent oil as lubricant, add oil to the oil level line. Too much oil will seep out along the pump shaft and drift low, and too little bearing will overheat and burn out causing accidents! During the operation of the water pump, the temperature of the bearing is up to 85 degrees and generally runs at about 60 degrees. If it is high, find the cause (whether there are impurities, whether the oil is black, whether water has entered) and deal with it in time!
