Embodiment Construction

[0028] The present invention will be described in further detail below according to the accompanying drawings.

[0029] As shown in the figure, the liquid nitrogen thermos is filled with liquid nitrogen, the electric heating core is fixed in the liquid nitrogen thermos, and the electric heating core is connected with the contact voltage regulator through wires. The oil supply pump is fixed on the oil tank, and is connected to the device to be lubricated through the oil supply copper pipe for lubrication. The amount of oil supply can be realized by controlling the rotation angle of the oil outlet valve. A plate radiator is installed on the oil return road, and the cooled lubricating oil is returned to normal temperature through the circulation of tap water in the plate radiator. The oil pump is connected to the oil outlet of the plate radiator through an oil return copper pipe, and the oil pump pumps the lubricating oil back into the oil tank to realize recycling.

Abstract

A small circulating lubrication system cooled by using liquid nitrogen comprises a liquid nitrogen refrigerating system and a lubrication oil circulating system. The cooling speed of lubricating oil in an oil supply pipe of the lubrication system is increased; and moreover, the lubrication oil which is heated by using a plate radiator is recycled. The whole small circulating lubrication system is simple in structure and convenient to operate, and is economical and practical.

Description

technical field [0001] The invention relates to the field of mechanical engineering lubrication, in particular to a lubrication system cooled by liquid nitrogen, which can be applied to laboratory friction and lubrication research. Background technique [0002] The function of the lubrication system is to deliver a certain amount of clean lubricating oil to the surface of the parts in relative motion to achieve liquid friction, reduce frictional resistance, and reduce wear of parts. And clean and cool the surface of the parts. [0003] The laboratory lubrication system usually consists of lubricating oil channels, oil pumps, and some valves. In the laboratory, the lubricating oil needs to be heated or cooled to different temperatures to simulate tests under different working conditions. [0004] Patent No. 200910065411.8 "Lubricating Oil Cooling System", this device uses cooling cages to cool lubricating oil, belongs to the field of cooling systems in wire production equipm...
