The influence of condensation point of hydraulic oil filter on the operation of hydraulic system.
2018/5/15 Viewers:
1. freezing point can be used to estimate wax content in waxy oil products to some extent. The more the paraffin content in the oil, the more easily solidified. If 0.1% paraffin is added to the oil, the freezing point will increase about 9.5~13C.. If the paraffin wax is removed from the oil, the solidifying point of the oil can be reduced.
2. used to indicate the grades of insulating oil and light diesel. If the freezing point of No. 10 insulating oil is not higher than -10C, the freezing point of insulating oil No. 25 is not higher than -25C, and the freezing point of insulating oil No. 45 is not higher than -45C. The condensation point of No. 0 diesel is not higher than 0C, and the point of No. 10 diesel is not higher than -10C. in actual work. The suitable grade of oil can be selected according to the requirements of operating conditions.
3. according to the climate of our country, 10 insulation oil is used in the south area of the Yangtze River basin generally for electrical equipment, and 25 insulation oil is used in the north of the Yangtze River to Shanhaiguan, and the temperature of the northeast is low. The transformer can use No. 25 insulating oil, but it also uses No. 45 insulating oil; the oil switch uses number 45. Insulating oil. If the transformer oil is too low and discontinued, the transformer can not run immediately, otherwise the transformer will be overheated and the heat can not go out, which threatens the safe operation of the equipment. If the oil switch oil loses liquidity, it will cause the switch tripping to be slow and the arc can not be extinguished in time. The contact point melts, causing damage to the equipment.
4. the freezing point of oil is mainly applied to the hydraulic oil pump of the steel steel friction pair. When the hydraulic pump is used for other material friction pairs, an oil pump manufacturer or an oil supply unit must recommend the oil pump load limits for this product.
5. the hydraulic oil solidifying point is the hydraulic oil used in the medium low pressure hydraulic system with large environmental temperature changes. The oil has good anti rust and anti oxygen properties, and on the basis of which added viscosity index improver, the oil has better viscosity temperature characteristics. This kind of oil has not been vigorously developed due to its low dosage.
6. hydraulic oil condensation point is original 32G and 68G in ordinary hydraulic oil. It was used as hydraulic guide oil. This product is a kind of hydraulic oil which is made up of oil agent or antiwear agent on the basis of HM hydraulic oil. The oil not only has excellent rust resistance, oxygen resistance and abrasion resistance, but also has excellent anti stick slip property. The product is mainly used for lubrication systems of various machine tools for hydraulic and guide rail or lubrication system of machine tool guide and hydraulic system of machine tools. In low speed conditions, the anti creeping effect is good. Hydraulic pressure guide oil belongs to this kind of product.
