万能试验机合理选择和使用油脂


  万能试验机合理选择和使用油脂,光学仪器上用的各种防尘脂、润油油脂必须是挥发度极低和化学稳定性好的材料,在光学仪器的金属零件上涂油脂时,首先要把零件清洗干净,让汽油挥发完后再涂油脂,并且要涂均匀而不能过多,距光学件10-15mm的范围内,禁止涂润滑油脂和防尘脂,防止油脂扩散引起油性雾。
如今万能试验机还越来越多的出现在塑料模塑和挤塑实验室中。一方面是因为它们越来越多的参与到新产品和新工艺的开发过程。另外一方面是因为它们在原材料以及成品质量控制上的精确性。在一些社会责任感很强的领域,如医用器械或汽车行业,需要塑料加工设备对他们的产品进行试验,也需要万能试验机的发挥更大的作用。同时,内部试验可以提高工艺控制的质量,减少废料率,从而也实现了真正的收益。仪器设备的高负荷使用,往往容易发生意外故障,特别是光学仪器若因维护和使用不当而起雾,就不能发挥仪器的正常作用,而带来工作上的障碍。所以高效的维护管理仪器设备已成为当今企事业单位有效降低成本,提高劳动生产率的有效手段。
