When the elastic oil tank according to the embodiment is installed, an oil inlet of the oil tank is firstly connected to an oil outlet of a pump, an oil inlet of the pump enters an open oil tank or an oil storage tank through a pipeline, an exhaust device of an upper end cover 11 of the oil tank is connected to an oil receiving device through a rubber pipe, the exhaust device of the upper end cover 11 of the oil tank is opened, and a motor and the pump are started. Along with the continuous rotation of pump fills oil into the oil tank, the exhaust apparatus of oil tank is the exhaust gas constantly, can observe inside fluid filling state through transparent upper end cover 11. When a little air is left in the oil tank, the exhaust valve is closed, and the pump continues to fill the oil until the oil tank reaches 75% of the maximum height of the oil tank. The tank is then connected to the hydraulic system, in which case the actuators of the hydraulic system must be retracted. And starting the pump and the motor to enable the hydraulic system to operate circularly, and if the height of the oil tank is reduced to 25%, the oil tank needs to be filled with oil again to 75%, and then the oil tank is connected back to the hydraulic system. With the continuous circulation of the hydraulic system, the air inside the oil tank begins to accumulate on the upper end cover 11 inside the oil tank, and at the moment, the exhaust valve is opened to exhaust the air, so that the air hardly exists inside the oil tank. And then, continuously circulating the hydraulic system until the gas in the oil tank is not increased any more, and finishing the installation work of the elastic oil tank.
In the elastic fuel tank according to the present embodiment, in the initial state, the inner surface of the upper end cap 11 of the fuel tank is in contact with the upper end opening of the elastic means supporting tube 2. The force exerted by the spring 21 on the guide rod 3 and transmitted to the upper end cap 11 is minimal and the pressure inside the tank is minimal. When more oil in the hydraulic system enters the interior of the elastic body 1 through the lower port of the lower end cover 12, the elastic body 1 expands due to the increase of the oil. At this time, the upper end cap 11 moves upward against the elastic force of the spring 21 under the action of the hydraulic pressure, and the upper end cap 11 continuously moves upward until the limit ring 25 on the limit rod 24 contacts the second boss on the elastic device support cylinder 2, at which time the upper end cap 11 reaches the limit position.
When the hydraulic system needs more oil, the oil flows to the hydraulic system from the inlet and the outlet, the oil in the elastic main body 1 is reduced, and the elastic main body starts to contract. The upper end cap 11 is moved downward and the spring 21 starts to recover until the upper end opening of the elastic means support cylinder 2 contacts the inner surface of the upper end cap 11 and the first boss contacts the stopper ring 25.
Of course, the working state of the oil tank is related to the type of the actuator, for example, when the actuator is a single-acting piston cylinder, the upper end cover 11 of the oil tank will move up and down continuously, and when the actuator is a double-acting cylinder, the upper end cover 11 of the oil tank will remain substantially stationary.
