Description

【Technical field】 [0001] The invention relates to an oil tank in a hydraulic system, in particular to a system for treating hydraulic oil with magnetization, centrifugation, electric hammer adsorption and rotating magnetic field, and belongs to the technical field of hydraulic oil tanks. 【Background technique】 [0002] Statistics at home and abroad show that about 70% to 85% of hydraulic system failures are caused by oil pollution. Therefore, the pollution control of the hydraulic system has become a common concern of the hydraulic industry and various industrial sectors at home and abroad. Solid pollution and gas pollution are the two main forms of hydraulic pollution. [0003] Under the conditions of atmospheric pressure and room temperature, the oil contains about 9% of the volume of air, and a part of the air dissolves into the oil. This dissolved air will not affect the mechanical properties of the hydraulic system, the volume elastic coefficient and the viscosity of...

AI Technical Summary

Problems solved by technology

[0008] 1. It is necessary to add a whole set of centrifugal device, the equipment is complicated, the cost is high, and it will bring secondary pollution to the oil at the same time

[0009] 2. The volume of the oil tank is large, and the oil has poor magnetic permeability. The strong magnetic magnet has a small force on the micron-sized particles in the oil, resulting in long adsorption time and poor adsorption effect.

[0010] 3. Some magnetized particles enter the hydraulic circuit and are adsorbed on the hydraulic components, causing component failure and difficult to clean and remove

However, since the air bubbles mixed into the return oil are small and the viscosity of the oil is relatively high, there is a problem that it takes a long time for the air bubbles to rise to the oil surface and disperse into the air, during which time the hydraulic device cannot work

However, the defoaming mechanism of the above-mentioned oil tank is natural defoaming, and there are still problems such as long defoaming time and low efficiency, especially for the working conditions with drastic flow changes.
