Description
Technical Field
The utility model belongs to the technical field of hydraulic oil vacuum filling, and is used for filling hydraulic oil into a hydraulic suspension system, in particular to a liquid storage tank assembly capable of vacuum dehydration and filling of hydraulic oil.
Background
At present, when hydraulic oil is filled in a vehicle hydraulic suspension system, a general oil tank is generally used and is directly filled through a filling pump assembly (each overflow pipeline and a fluid supplementing assembly of a filling machine are directly connected with the oil tank).
The common hydraulic oil generally contains partial moisture which is used as a pollutant in the lubricating oil, and has serious influence on the quality, performance and service equipment of the lubricating oil, and even causes huge economic loss of liquid. The oil tank with the original structure is used for direct filling, so that oil products are deteriorated, the use safety of mechanical equipment is jeopardized, and economic loss is caused.
The harm caused by mixing water into the hydraulic oil is as follows:
1. hydraulic oil can dissolve part of the air and sometimes also suck in air bubbles. Air mixed in the hydraulic oil can accelerate the oxidative deterioration of the hydraulic oil, and also can cause noise, cavitation, vibration and the like.
2. After water is mixed into the hydraulic oil, the viscosity of the hydraulic oil cylinder is reduced, the hydraulic oil is oxidized and deteriorated, water bubbles are formed, the lubricating performance of the hydraulic oil is deteriorated, and cavitation is generated. After a certain amount of water is mixed, the hydraulic oil is emulsified to a cloudy state. The cloudy emulsified oil enters the hydraulic system, so that the inside of the hydraulic element is rusted, the lubricating performance of the hydraulic element is reduced, the abrasion of parts is increased, and the efficiency of the system is reduced.
3. After the iron-based metal in the hydraulic system is rusted, the peeled iron rust flows in the hydraulic system pipeline and the hydraulic element, and spreads, so that the whole system is rusted, and more peeled iron rust and oxide are generated.
4. The water mixed into the oil also reacts with certain additives in the oil to produce contaminants such as sediment and gum, which accelerate the deterioration of the oil.
5. The action of sulfur and chlorine in water and oil produces sulfuric acid and hydrochloric acid, which aggravates the abrasion wear of the components, accelerates the oxidative deterioration of the oil, and even produces a lot of sludge.
6. These water contaminants and oxidation products, which then become catalysts for further oxidation, eventually lead to hydraulic component plugging or seizing, causing a series of failures such as hydraulic system malfunction, piping plugging, cooler efficiency degradation, and oil filter plugging.
In the prior art, vacuum oil filtering equipment is already available, the specific structure can refer to the utility model patent with the patent number of CN201711338482.1, the publication number of CN107930242A and the patent name of a novel energy-saving environment-friendly vacuum oil filtering equipment, but the equipment cannot be directly used for filling hydraulic oil in a hydraulic suspension system.
