Grease lubrication is a lubricating device, developed in recent years with the grease mist lubrication is similar, but different from the grease mist lubrication. Grease lubrication and grease mist lubrication, are thin grease transported to the bearing compressed air as power, grease lubrication is not grease hit a fine mist, but the use of compressed air flow to the grease along the pipeline transportation bearings, eliminating the need for condensation. Who can the flow of liquid can be transported, without the restrictions of viscosity.
The higher the pressure of air transportation, 3 × 105Pa about, the bearings inside the pressure is also higher, 0.3 × 105Pa about. Normal operation, the bearings inside to maintain some level of lubricating grease, to grease based on actual consumption, so the lubricant gap supply, is the continuous supply of air. Should grease and gas mixture due to lubrication points are more evenly were transported to the various bearings, or a problem in a few years ago, invented Elliott grease distributor, to solve this problem, thus making the grease lubrication to the development and application, and to obtain satisfactory results.
Grease lubrication has the following advantages:
1. Are environmentally friendly, because there is no grease mist, the surrounding environment from pollution.
2. Precision measurement, the grease and air two components can be measured accurately, according to the different needs of transportation to each lubrication point, this is a very economical system.
3. Nothing to do with the grease viscosity. Who can the flow of grease can be transported. It does not exist the problem of high viscosity atomization difficult, because it does not require atomization.
4. The system can be monitored, the working conditions of the system very easy to implement electronic monitoring.
5. Particularly suitable for rolling bearings, especially heavy-duty rolling mill roll neck bearings, air-cooled effect, can reduce the bearing operating temperature, thus extending bearing life.
6. Fuel consumption is minimal. Only consume the amount of fat, 1/10 to 1/20.
