hydraulic oil tank

A hydraulic oil tank refers to a container used to store the oil required to ensure the operation of a hydraulic system. According to whether the fuel tank level is connected to the atmosphere, the fuel tank can be divided into two types: open and closed

The main function of a hydraulic oil tank is to store oil, as well as to dissipate heat, precipitate impurities, and allow air in the oil to escape. According to whether the fuel tank level is connected to the atmosphere, the fuel tank can be divided into two types: open and closed. Open type oil tanks are used in general hydraulic systems; Closed oil tanks are used underwater and in hydraulic systems with strict requirements for working stability and noise.

The volume of the oil tank must ensure that when the equipment stops running, all the oil in the system can return to the hydraulic oil tank under its own weight. The effective volume of the oil tank (the volume of the tank when the liquid level occupies only 80% of the height of the hydraulic oil tank) is generally greater than 3 times the flow rate per minute of the pump (1.5 to 2 times for the walking device). In low-pressure systems, the effective volume of the fuel tank is usually taken as 2-4 times the flow rate per minute, while in medium and high-pressure systems it is 5-7 times the flow rate per minute; If it is a high-pressure closed-loop system, the effective volume of its oil tank should be determined by the amount of external circulation oil or supplementary oil required; For hydraulic systems with heavy workloads and long-term continuous operation, the capacity of the oil tank needs to be determined by calculation based on the heat generation of the hydraulic system.
