按照选用油脂机械工作条件的依据是怎么来判断

　

　　按照选用油脂机械工作条件的依据是怎么来判断的;

　　According to the selection of the basis of the work conditions of oil machinery is how to determine the;

　　一、负荷

　　One, load

　　负荷大，应选用粘度大或油性、极压性好的润滑油。反之，负荷小，应选用粘度小的润滑油。间歇性的或冲击力较大的机械运动，简略损坏油膜，应选用粘度较大或极压性较好的润滑油，或用这种润滑油制成的锥入度较小(较硬)的润滑脂。

　　The load is big, should choose the viscosity big or the oil, the extreme pressure good lubricating oil. On the contrary, the load is small, should use small viscosity of lubricating oil. Intermittent or impact force larger mechanical movement briefly damage of oil film, viscosity larger or better lubrication oil extreme pressure, or with the lubricating oil made from cone penetration small (harder) shall be used in grease.

　　二、速度

　　Two, speed

　　速度高，需选用粘度较小的润滑油或用粘度娇小的润滑油制成的润滑脂;反之，则用粘度较大的润滑油或用粘度较大的润滑油制成的润滑脂。

　　High speed, the need to use low viscosity lubricating oil or lubricating grease made of lubricating oil viscosity Petite; on the contrary, with high viscosity lubricating oil or made of high viscosity lubricating oil grease.

　　对于高速滚动轴承的选脂，为了补足全部脂的机械安定性和成渠性，以及战胜离心力的效果，选用稠度较大的3号润滑脂;对通常转速不太高的轴承来说，为了降低轴承的转矩，特别是发起转矩，则尽可能选用低稠度的润滑脂。

　　For high speed rolling bearings of the fat, in order to make up all of the mechanical stability and drainage, as well as the effect of the centrifugal force, the best selection of the large number of grease 3, the general speed is not too high, in order to reduce the torque of the bearing, in particular, the launch torque, it is possible to use a low consistency grease.

　　三、温度

　　Three, temperature

　　在高温条件下，应选用粘度较大、闪点较高、油性好以及氧化安定性好的润滑油或用热安定性好的基础油和稠化剂(锂皂、负荷钙皂、负荷铝皂等)制成的滴点较高的润滑脂。

　　In high temperature conditions, should choose viscosity, high flash point, good for oily and good oxidation stability of lubricating oil or thermal stability of base oils and thickeners (lithium soap, load calcium soap, load aluminum soap, etc.) made the drop point high grease.

　　在低温条件下，应选用粘度较小，凝点低的润滑油或用这种油制成的低温功用较好的润滑脂。温度改变大的抵触部位，应选用粘温功用较好的润滑油或运用温度规模较宽的润滑脂(如通用锂基脂)。

　　Under the low temperature condition, should choose the smaller viscosity, low solidifying point of lubricating oil or using the oil made from low temperature function better grease. Temperature changes large conflict parts, should use viscosity temperature function better lubricating oil or using a temperature scale wide grease (such as general lithium grease).

　　四、湿润

　　Four, wet

　　在湿润的作业环境里，或许与水触摸较多的作业条件下，应选用抗乳化才干较强的油性、防锈功用较好的润滑油、脂，不能选用钠基脂。

　　In the wet operating environment, and perhaps with water to touch more operating conditions, should choose to have a strong anti - emulsification ability of oil, anti - rust function of good lubricating oil, grease, can not choose sodium base grease.

　　五、抵触表面精度

　　Five, inconsistent with the surface accuracy

　　表面粗糙，需要运用粘度较大或锥入度较小的润滑油、脂。反之，应选用粘度较小或锥入度较大的润滑油、脂。

　　The surface roughness, lubricating oil, grease required by viscosity larger or smaller cone penetration. On the other hand, should choose low viscosity or large cone penetration of lubricating oil, grease.

　　六、抵触表面方位

　　Six, resistance to surface orientation

　　在笔直导轨、丝杠上，润滑油简略丢掉，应选用粘度较大的润滑油。立式轴承宜选用润滑脂，这样能够减少丢掉，坚持润滑。

　　In the straight guide, lead screw, lubricating oil is briefly lost, should choose the larger viscosity of lubricating oil. Vertical bearing appropriate selection of grease, so that can reduce the lost, adhere to the lubrication.

　　七、润滑办法

　　Seven, lubrication method

　　在循环润滑系统中，需要换油周期长、散热快，应选用粘度较小，抗泡沫性较好的润滑油。

　　In the circulating lubrication system and need to oil change cycle is long, fast heat dissipation, should choose the smaller viscosity, anti foam and anti - oxidation stability better lubricating oil.

　　在飞溅及油雾润滑系统中，为减轻润滑油的氧化效果，应选用加有抗氧、抗泡添加剂的润滑油。在会集润滑系统中，为便于运送，应选用低绸度的1号或1号润滑脂。

　　In the splash and oil mist lubrication system, in order to reduce the oxidation effect of lubricating oil, we should select the lubricating oil with anti oxygen and anti foam additive. In the convergence of the lubricating system, for the convenience of transportation, should use low degree of silk No. 1 or No. 1 grease.郑州企鹅可靠的设计，制造，安装经济，有质量保证的榨油行客户世界各地，如果您有任何问题，请与我们联系.0371-86661079
