[0082] Example 2: as Figure 5 As shown, a method for realizing viscosity-temperature performance compensation by utilizing the nano-magnetic fluid hydraulic pump station, the specific steps are:

[0083] Step1: Monitor the temperature of the magnetic nanofluid 9 and collect its temperature data;

[0084] Step2: Pass the direct current into the electromagnetic coil to generate a constant magnetic field, so that the magnetic field covers the nano-magnetic fluid 9, and at the same time, convert the direct current into a digital signal and input it into the temperature control module;

[0085] Step3: Judge the temperature of the nano-magnetic fluid 9 through the temperature control module, and judge whether it reaches the rated minimum working temperature;

[0086] Step4: If the temperature of the nano-magnetic fluid 9 is lower than the rated minimum operating temperature, connect the AC power supply to the electromagnetic coil to generate an alternating magnetic field, so that ...

[0090] Embodiment 3: a kind of method that utilizes described nanometer magnetic fluid hydraulic pump station to realize medium dispersion stability detection and redispersion, and concrete steps are:

[0091] Step1: Turn on the force sensor 8-5, perform calibration and zero adjustment, and set the glass window 8-1 at the position where the dispersion detector 8 is installed on the mailbox wall.

[0092] Step2: Adjust the distance between the upper and lower dispersity detectors 8 and the tested medium, so that the distance between the permanent magnets 8-2 of the two dispersity detectors 8 and the glass window 8-1 is both 0.1 mm.

[0093] The attractive force between the permanent magnet and the nanomagnetic fluid is very weak. It needs to be close to collect, and the wall of the fuel tank is thick due to the support function and the installation of other devices.

[0094] Therefore, arranging a glass window structure on the wall of the fuel tank can make the permanent magnet ...

Description

technical field [0001] The invention relates to a nano-magnetic fluid hydraulic pump station and a using method thereof, belonging to the technical field of hydraulic transmission. Background technique [0002] The hydraulic pump is the power element of the hydraulic system. The existing hydraulic system mostly uses mineral hydraulic oil as the working medium, but the viscosity changes greatly with temperature: (1) The viscosity of the hydraulic oil increases in the low temperature environment, which leads to the increase of the oil suction resistance of the hydraulic pump, the difficulty of oil absorption, and the vacuum degree of oil absorption. large, the probability of cavitation increases, the volumetric efficiency is low, and the working noise is large. (2) Under the high temperature environment, the viscosity of the hydraulic oil decreases, the sealing performance of the hydraulic pump decreases, the leakage increases, and the volumetric efficiency decreases. In add...
