Problems solved by technology
If the air circulation in the fuel tank is obstructed, the air pressure in the fuel tank will be too high or too low. If the air pressure is too high, it will hinder the oil return of the system and increase the system pressure, which is not conducive to structural safety; if the air pressure is too low, it will hinder the oil pump. Oil absorption will increase the load of the oil pump, reduce the life of the oil pump, and even cause insufficient oil supply to the system, and the phenomenon that the action of the actuator will not be in place.

The invention relates to an oil spillage preventing air filtering device and belongs to the field of hydraulic control. The air filtering device comprises a tank. Two air channels with the same structure are formed in the tank and connected through a vent pipeline. The vent pipeline is provided with an air filter. A pipeline of each air channel is provided with a one-way valve and a prepressing type one-way valve. The air channels are connected with the oil tank through the vent pipeline. When air pressure in the oil tank is higher than outside atmospheric pressure, the prepressing type one-way valves are opened, and surplus gas in the oil tank is released to atmosphere; when the air pressure in the oil tank is lower than the outside atmospheric pressure, the one-way valves are opened, and negative pressure is utilized for sucking air into the oil tank, so that ventilation in the oil tank is achieved; the two one-way valves are arranged in a left and right mode, the air filter is arranged between the two one-way valves, and the purpose is to ensure ventilation in the oil tank and avoid oil leakage when the oil tank is inclined by any angle. The air filtering device can be applied to oil tanks of engineering vehicles and equipment and has wide application prospects.
Description
technical field [0001] The invention relates to an oil spill prevention air filter device, which belongs to the field of hydraulic control. technical background [0002] At present, the climbing ability of most construction vehicles is limited by the fuel tank. The air filter is placed in the middle of the upper part of the fuel tank. Because the fuel tank is adapted to a small inclination angle, the internal air is required to circulate normally and the oil will not enter the air filter. inside the cleaner. When the engineering vehicle is climbing a slope, the fuel tank is tilted. Due to the excessive inclination of the ordinary fuel tank, the oil will enter the air filter, resulting in the air filter not working normally and losing its function, hindering the air circulation in the fuel tank, causing Fuel tank leaks. During normal operation, the height of the liquid level in the fuel tank is constantly changing, the temperature of the oil is gradually rising, and the int...
