The invention provides an edible-oil processing technology for decreasing the content of trans-fatty acid and removing a plasticizer. The edible-oil processing technology includes the steps of bleaching oil filtering, deacidifying and deodorizing, primary plastic removing, secondary plastic removing, fatty acid and plasticizer collecting, product oil cooling and filtering and the like, the plasticizer index of the produced product oil is lower than the national standard, wherein DBP is smaller than or equal to 0.04 ppm, DEHP is smaller than or equal to 0.4 ppm, and the rising value of the trans-fatty acid is smaller than 0.5%. By means of the processing technology, the plasticizer is removed; meanwhile, forming of the trans-fatty acid is inhibited, and the content of the trans-fatty acid is decreased. The plasticizer in grease is effectively removed through the pure physical technology, and the problem that plasticizers of product oil in domestic grease processing plants is seriously exceeded the standard at present is solved.

A lubricating oil cooling and filtering integrated device for a single-stage high-speed centrifugal blower is characterized in that a main oil pump 5, an oil cooler 6 and an oil filter 7 are all fixedly mounted on a base 3, the oil inlet of the main oil pump 5 is communicated with an oil inlet pipe connector 8, the oil outlet of the main oil pump 5 is communicated with the oil inlet of the oil cooler 6 through a first pipeline 10, the oil outlet of the oil cooler 6 is communicated with the oil inlet of the oil filter 7 through a second pipeline 11, the oil outlet of the oil filter 7 is communicated with an oil outlet pipe connector 9 through a third pipeline 12, and the first pipeline 10 is communicated with the second pipeline 11 through a fourth pipeline 13. The lubricating oil cooling and filtering integrated device for the single-stage high-speed centrifugal blower has the benefits that the cooling and filtering device and the pipelines are integrally arranged on the independent base, and can be separated from the blower and communicated with an oil station and a blower body of the blower through hoses, so that the oil pipelines are less affected by the vibrations produced during the operation of the blower body, the service life of an oil system is prolonged, and convenient and rapid mounting and overhauling are achieved.

The invention discloses a segmented heating and cooling quenching process for a wheel body of a thrust wheel. The process comprises the following steps of 1, placing and positioning the thrust wheel, wherein the thrust wheel is grabbed through a mechanical arm and placed on a support platform in a quenching device; 2, sequentially conducting intermediate frequency, high frequency and intermediate frequency induction heating on the thrust wheel through induction coil bodies; 3, cooling the thrust wheel obtained after induction heating, wherein spray cooling implemented through water, saline water and oil is sequentially conducted on the thrust wheel obtained after induction heating. According to the thrust wheel quenching process, the water-saline water-quenching oil cooling process is adopted, so that the problems that in the prior art, the quenching speed of a thrust wheel is low, the thrust wheel is deformed and cracked, and the thrust wheel is inconsistent in hardness after being quenched; the quenching process has the advantages of being uniform in thrust wheel hardness and high in quenching efficiency.

The invention discloses a 5CrNiMo tempering process. The process includes: 1) determination of the tempering heating temperature of 5CrNiMo at 490DEG C-530DEG C; 2) determination of the tempering time: the tempering heat preservation time of steel with effective thickness of 300mm is 6h, and the heat preservation time of alloy steel can be increased by 1/3, therefore the hammer forging die 5CrNiMo tempering time is 7h; 3) determination of the tempering cooling mode: oil cooling is carried out after furnace discharge to prevent temper brittleness, in order to eliminate the stress generated by oil cooling, retempering can be performed at 160DEG C-180DEG C, and after tempering, the product cannot be cooled to room temperature in oil, otherwise cracking is likely to occur; 4) determination of the tempering hardness: the tempering hardness is within a required range of 32-35HRC; and 5) guarantee of sufficient forging die tempering time to avoid cracking caused by excessive high hardness at the core of the die; and prevention of second class brittleness in cooling after forging die tempering, and at the same time implementation of second tempering with a temperature about 10DEG C lower than the first tempering temperature and a holding time shortened by 20%-25%.

The invention discloses an automobile oil cooler. The automobile oil cooler comprises an oil cooler pipe body, wherein the oil cooler pipe body has inner and outer layer pipe walls; the pipe ends of the inner and outer layer pipe walls are sealed; an oil passing cavity is defined between the inner and outer layer pipe walls; an oil inlet is formed in one end of the outer layer pipe wall, and an oil outlet is formed in the other end of the outer layer pipe wall; and the oil inlet and the oil outlet communicate with the oil passing cavity. The automobile oil cooler is characterized in that irregularly distributed first pits are densely arranged on the outer layer pipe wall; irregularly distributed second pits are densely arranged on the inner layer pipe wall; some of the first pits and the second pits align to each other, and some of the first pits and the second pits are staggered; and the depth of the first pits and the second pits is equal to a half of the distance between the inner layer pipe wall and the outer layer pipe wall. According to the automobile oil cooler, the structure is simple, the cooling area is increased, a better engine oil cooling effect can be achieved, and the production cost is effectively reduced.
