Vibrating screen is the equipment for screening materials through the rotation of eccentric shaft with connecting rod forcing the machine do reciprocating motion along a certain direction. In the process of using, maintain the screen regularly, especially eccentric shaft. So how to select lubricating oil in the maintenance of eccentric shaft?
When lubricate the eccentric shaft of vibrating screen, we should select lubricating oil and grease suitable for the machine. Due to different varieties, there is a big difference in performance, so must pay attention to the selection of lubricating oil or grease. Common lubricating greases of vibrating screen are albany grease, sodium soap grease, calcium-sodium base grease, lithium lubricating grease, aluminium base grease, molybdenum disulfide lithium-based grease and so on. Lubricating grease consists of base oil, thickener and additive, and has the lubrication effect on eccentric axis for a long time. Sealing device of vibrating screen has good enclosed simple structure and is widely used. Volume of addition of lubricating grease in eccentric axis of vibrating screen should be one half or one third of inner space of eccentric axis, and reduce to one third at least when axis high-speed running to avoid machine damage.
When eccentric axis is running with high-speed and high-temperature, we need use lubricating oil instead of grease. Common lubricating oil is machine oil, cylinder oil, high-speed machine oil, compressor oil, transformer oil, steam turbine oil and so on. Lubricating oil can take a lot of heat away from the screen and reduce the noise and vibration. When select lubricating oil, viscosity is a important feature which should be controlled in 12cst—15cst. The higher speed of eccentric axis, the lower viscosity of lubricating oil, and it is better to use lubricating oil with high viscosity when heavy load.
