The reasons for the use of vacuum oil immersion machines for powder metallurgical oil-bearing:
1, because of the conditions necessary for the process of small bearings, when producing small bearings, they are all sintered by powder metallurgy. Then during the sintering process, after sintering them through a high temperature furnace, there will be a lot of small hair gaps. hole. To make up for this shortcoming, we need to use our vacuum impregnator to place the impregnated product in the impregnated tank and fill its impregnated liquid into the sintered small bearing gap hole through vacuum action.
2) Because the powder metallurgical product is insulated(vacuum oil immersion machine) under vacuum negative pressure, the insulating oil can penetrate quickly, evenly and completely into each fine pores and voids of the coil, and the surface is smooth. Through the vacuum insulation treatment of products, its insulation can greatly improve, reduce the power consumption of products, vibration noise and low temperature rise and other significant effects, to improve the quality of products, prolong the life of products has a good effect. Therefore, the use of vacuum oil immersion is the traditional oil immersion incomparable process choice and improve market competitiveness equipment.
The advantages of a vacuum oil immersion machine:
Through the vacuum osmosis treatment of products, its oil content is sufficient, performance can be greatly improved, lubrication performance improved, vibration noise and temperature rise and other significant effects, to improve the quality of the product, the extension of the product life has a good effect. Vacuum oil immersion time is reduced by several times compared with the traditional oil immersion process, and the time and loss of the material in the oil drip process are also shortened, which directly reduces the production cost and improves the product quality and market competitiveness. Vacuum oil immersion machine has a good and significant effect on the parts of powder metallurgical structure such as metal oil bearing.
The above is the reason and advantage of the use of vacuum oil immersion machine for powder metallurgical oil bearing. The powder metallurgical oil bearing performs oil seepage treatment under vacuum negative pressure, and the lubricant can penetrate quickly, evenly, and completely into each fine pores and voids of the powder metallurgical oil bearing., and the surface is smooth.
