The main function of the hydraulic oil tank in the hydraulic system is to store oil, dissipate heat, separate the air contained in the oil and eliminate bubbles. The capacity of the fuel tank must be considered firstly.
Generally, mobile equipment takes 2 to 3 times the maximum flow rate of the pump, and fixed equipment takes 3 to 4 times; secondly, consider the oil level of the fuel tank. When all the hydraulic cylinders of the system are extended, the oil level of the fuel tank should not be low. At the lowest oil level, the oil level should not be higher than the highest oil level when the oil cylinder is retracted; finally, considering the structure of the oil tank, the partition in the traditional fuel tank cannot serve as a deposit for dirt.
A vertical partition should be installed along the longitudinal axis of the fuel tank. There is a space between one end of this partition and the end plate of the fuel tank to connect the spaces on both sides of the partition. The oil inlet and outlet of the hydraulic pump are arranged on both sides of the partition at the unconnected end, so that the distance between the oil inlet and the oil return is the farthest. The hydraulic oil tank plays a more role in heat dissipation.
