At this stage, there are two major types of key conditions to replace imported vegetable oil with domestic vegetable oil: first, the price of imported vegetable oil is relatively expensive，The application cost is too high，Domestic production of such vegetable oils;Second, some imported product type vegetable oils and fats，However, there are some problems such as the long-term application of lubricating oil tone black，Pipe clogging，There is no domestic vegetable oil replacement，This kind of vegetable oil is also produced domestically。On the other hand, the domestic production of imported vegetable oils also has its rights and interests, and the immediate economic benefits are to save costs for the company.Lubricating oilNot only the cost of vegetable oil itself, but also a lot of costs can be saved in transportation costs due to the application of domestic production of vegetable oil and oil。

      Lubricating oil is国内生产制造的，要考虑到下列标准： (1)确保机器设备正常润化，生产制造正常运作; (2)成本费小于進口油; (3)克服一些進口油在应用上存在的不足; (4)需类似或特性相仿; (5)是质量稍高于進口Lubricating oil。 The whole process of domestic production of imported vegetable oil and fats is a whole process of experiment, use and application，Some basic methods are summarized as follows: (1) Analysis of the natural environment and working conditions on the spot of production and manufacturing: In order to achieve the requirements of machine and equipment polishing，兰州Lubricating oilIt is necessary to analyze the working condition wetting standard and wetting position, such as the machine speed ratio, impact load, temperature and water solubility, etc., so as to clarify the characteristics of domestic grease。

     Model selection of domestic vegetable oil: According to the analysis of the above working status, the domestic grease model specifications are used to ensure that the various performance parameters of domestic production of lubricating oil are many than that of imported fat, and the current machinery and equipment can not be modified。 Test: The application of technical professional way to test various performance parameters of vegetable oil。 Use on the spot: formulate application plans, and send professional and technical personnel to track and check the application status of vegetable oil on the spot。 Announce applications:Lubricating oilAfter the use of time, under the standard of achieving various performance parameters and ensuring the normal refinement of the machine and equipment, the application can be announced after the evaluation of its economic benefits。
