Today, I will introduce the selection and installation of a hydraulic pump oil tank.
1. Selection of hydraulic oil tank
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 foam. When selecting a fuel tank, first consider its capacity. 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 oil tank. When all the hydraulic cylinders of the system are extended, the oil level of the oil 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 diaphragm in the traditional oil tank cannot play the role of depositing dirt, and a vertical diaphragm should be installed along the longitudinal axis of the oil tank. There is a space between one end of the diaphragm and the end plate of the fuel tank so that the space on both sides of the diaphragm is connected, and the oil inlet and outlet of the hydraulic pump are arranged on both sides of the non-connected end of the diaphragm so that the distance between the oil inlet and the oil return is the farthest. The hydraulic oil tank has a more cooling effect.

2. Installation of the hydraulic oil tank
The different installation positions can be divided into top-mounted, side-mounted, and bottom-mounted.
The top-mounted fuel tank installs the hydraulic pump and other devices on the upper cover plate with good rigidity has a compact structure, and is the most widely used. In addition, heat dissipation fins can be cast on the fuel tank shell to enhance the heat dissipation effect, that is, to improve the service life of the hydraulic pump.
The side-mounted fuel tank is to install the hydraulic pump and other devices next to the fuel tank. Although the floor space is large, the installation and maintenance are very convenient. It is usually used when the system flow and fuel tank capacity are large, especially when one fuel tank supplies multiple hydraulic pumps. Used when fueling. Because the oil level of the side-mounted fuel tank is higher than the oil suction port of the hydraulic pump, it has a better oil suction effect.
The under-mounted fuel tank places the hydraulic pump under the fuel tank, which is not only easy to install and maintain but also greatly improves the suction capacity of the hydraulic pump.
