Abstract

The invention discloses an alternate adsorption dehydration method for hydraulic fluid, and belongs to the technical field of hydraulic fluid. According to the invention, the hydraulic fluid can be dehydrated through an adsorption column, water in the hydraulic fluid is absorbed by utilizing a water absorption alternation ball on a dehydration path, and internal expansion action is triggered after the water is absorbed to a certain degree, so that the magnetic field shielding state is changed from the original complete magnetic shielding or strong magnetic shielding state to the weak magnetic shielding state, active migration can be achieved under the adsorption effect of the fixed iron block, then the other water absorption rotation balls are squeezed for position complementing and water is continuously absorbed, then rotation type dehydration treatment of the water absorption rotation balls is achieved, good water-absorbing capacity is always kept, the situation that water is desorbed and enters the hydraulic fluid for the second time due to long-time water absorption is not easy to occur, excellent dehydration effect and efficiency can be ensured, then the use effect of the hydraulic fluid is improved, and the service life of the hydraulic fluid is prolonged.

Description

technical field [0001] The invention relates to the technical field of hydraulic fluid, and more specifically, relates to a hydraulic fluid rotation adsorption and dehydration method. Background technique [0002] Hydraulic fluid is the working medium for transmitting power and signals in the hydraulic system. Some hydraulic fluids also play the role of lubrication, cooling and rust prevention. Whether a hydraulic system can transmit work reliably and efficiently depends to a large extent on the hydraulic fluid used in the system. [0003] Hydraulic equipment mainly uses petroleum-based hydraulic fluid, and some use seawater mixed with fresh water as hydraulic fluid. In order to improve the performance of hydraulic fluid to meet the different requirements of hydraulic equipment, various additives are often added to the base oil. [0004] Common hydraulic fluids on the market include: high water-based fire-resistant hydraulic fluid (HFA), water-glycol hydraulic fluid (HFC)...
