Background
The rotating parts of the equipment are all provided with bearings, and lubrication of the bearings is an optimal choice for reducing wear and friction power consumption. More than 90% of rolling bearings are lubricated with grease. During the operation of the equipment, the lubricating grease in the bearing can cause the lubricating performance of the lubricating grease to be reduced due to extrusion, abrasion, oxidation, pollution and the like. Therefore, the grease must be replenished periodically to improve the lubricating performance of the grease and meet the lubricating requirements of the equipment. When the lubricating grease is replenished, not only new lubricating grease needs to be filled, but also the lubricating grease with part of lubricating performance reduced needs to be discharged, so that the performance of the lubricating grease is ensured to be improved, and the lubricating requirement of the bearing is met.
After a rotating part of the equipment runs for a long time, most of the waste oil removing devices are ineffective in working, waste oil cannot be collected according to an ideal state, and a small part of the waste oil only collects basic thin oil separated out by a small amount of oil. If the lubricating system forcibly supplements lubricating grease, the waste grease in the bearing cannot be reasonably discharged through the waste oil device and can only be discharged through breaking the oil seal. Along with the rotation of equipment, waste oil is got rid of and is got rid of in the environment, causes serious pollution, has brought very big inconvenience for maintenance and repair work at ordinary times. In addition, because old lubricating grease cannot be discharged and occupies an effective lubricating part, additional new lubricating grease cannot be injected, most of the lubricating grease overflows from an oil seal, and poor lubrication of the bearing is caused.
