碎石机对于润滑油有何要求?
网址:http://www.dhfjx.cn    发布时间:2021-06-04
所有的机械设备保养都需要润滑油,当然矿山机械设备也不例外。但是,由于设备运行环境的不同,对润滑油的性能和质量的要求也不同。制砂机、移动碎石机等设备是矿山机械中常常用的设备,尤其是大型砂石工程,而这些设备都是露天生产。该制砂机具有可靠性高、使用安装维护方便、运行维护成本低、经济性好、节能环保、无需附加装置等优点。但是他们的工作环境比较差,所以我们应该多注意日常保养和定期保养。
All machinery and equipment maintenance need lubricating oil, of course, mining machinery and equipment is no exception. However, due to the different operating environment of the equipment, the requirements for the performance and quality of lubricating oil are also different. Sand making machine, mobile gravel machine and other equipment are often used in mining machinery, especially in large-scale sand engineering, and these equipment are open-air production. The sand making machine has the advantages of high reliability, convenient use, installation and maintenance, low operation and maintenance cost, good economy, energy saving and environmental protection, and no additional device. But their working environment is poor, so we should pay more attention to daily maintenance and regular maintenance.
根据制砂机、移动碎石机等矿山机械的特点,对润滑油提出以下要求
According to the characteristics of sand making machine, mobile gravel machine and other mining machinery, the following requirements for lubricating oil are put forward
1. 矿山机械和油罐体积小,润滑油用量小,工作时油温高,这就要求润滑油具有良好的热稳定性和抗氧化性。
1. The volume of mining machinery and oil tank is small, the amount of lubricating oil is small, and the oil temperature is high when working, which requires the lubricating oil to have good thermal stability and oxidation resistance.
2. 由于矿山环境恶劣,煤尘、岩尘、水较多,润滑油很难不受这些杂质的污染,因此要求润滑油具有较好的防锈、防腐、抗乳化性能;当润滑油被污染时,其性能变化不会太大,即对污染的敏感性较小。
2. Due to the bad mine environment, there are many coal dust, rock dust and water, it is difficult for the lubricating oil not to be polluted by these impurities, so the lubricating oil is required to have good anti rust, anti-corrosion and anti emulsification performance; When the lubricating oil is polluted, its performance will not change much, that is, it is less sensitive to pollution.

3.露天矿机械设备冬、夏季温度变化较大,部分地区昼夜温差较大。因此,要求润滑油的粘度随温度的变化要小。温度高时,润滑油粘度不宜过低,以免形成润滑膜,发挥不了润滑作用。当温度较低时,粘度应过高,使启动和操作困难。
3. The temperature of mechanical equipment in open-pit mine varies greatly in winter and summer, and the temperature difference between day and night is large in some areas. Therefore, it is required that the viscosity of lubricating oil should be small with the change of temperature. When the temperature is high, the viscosity of lubricating oil should not be too low, so as to avoid the formation of lubricating film, which can not play the role of lubrication. When the temperature is low, the viscosity should be too high, which makes it difficult to start and operate.
4. 对于一些矿山机械设备,特别是在易发生火灾、爆炸事故的矿山中使用的机械设备,要求使用具有良好阻燃性的润滑剂(耐火液体),代替可燃性矿物油。
4. For some mining machinery and equipment, especially those used in mines prone to fire and explosion accidents, it is required to use lubricants (fire-resistant liquid) with good flame retardancy to replace combustible mineral oil.
5. 润滑剂对密封的适应性要好,避免损坏密封。希望移动碎石机、砂机等所有机械设备用户可以根据自己的设备运行环境选择合适的润滑油,并对设备进行各方面的维护。
5. The lubricant has good adaptability to the seal to avoid damaging the seal. It is hoped that all mechanical equipment users, such as mobile gravel machine and sand machine, can choose suitable lubricating oil according to their own equipment operation environment, and maintain the equipment in all aspects.
