Selection of hydraulic oil tank: The effect of the hydraulic oil tank in the hydraulic system is oil storage, heat dissipation, separation of air contained in the oil and elimination of foam. When selecting a fuel tank,hydraulic pump take into account the capacity of mobile equipment to take 2~3 times the pump flow,hydraulic pump and fixed equipment to take 3~4 times; secondly, consider the oil level of the fuel tank. When all the hydraulic cylinders of the system are extended,hydraulic pump the oil level of the fuel tank shall not be lower than low oil. When the oil cylinder is retracted, the oil level shall not be higher than the high oil level; after all,hydraulic pump considering the structure of the oil tank,hydraulic pump the partition in the traditional oil tank cannot play the role of accumulating dirt. A vertical partition should be installed along the longitudinal axis of the oil tank. There is a space between one end of this partition and the end plate of the oil tank to make the space between the two ends of the partition communicate. The oil inlet and outlet of the hydraulic pump are arranged at the two ends of the partition that is not connected,hydraulic pump so that the distance between the oil inlet and the oil return is long. More heat dissipation effect.
The equipment of hydraulic oil tank can be divided into upper type, side type and lower type according to the different equipment orientation. The upper-mounted oil tank puts hydraulic pumps and other equipment on the upper cover plate with better rigidity,hydraulic pump and its structure is compact and widely used. In addition,hydraulic pump heat dissipation fins can be cast on the oil tank shell to enhance the heat dissipation effect, that is, increase the service life of the hydraulic pump.
The side-mounted fuel tank is to place hydraulic pumps and other equipment around the fuel tank. Although it occupies a large area,hydraulic pump the equipment and repairs are very convenient. It is usually selected when the system flow and fuel tank capacity are large, especially when one fuel tank is used for multiple hydraulic pumps. Use when supplying oil. Because the oil level of the side-mounted oil tank is higher than the suction port of the hydraulic pump, it has a better oil suction effect. The bottom-mounted oil tank is to place the hydraulic pump under the oil tank,hydraulic pump which is not only convenient for equipment and repair, but also the suction of the hydraulic pump can be adjusted to improve.
