Abstract

Disclosed is a hydraulic safety oil tank. The hydraulic safety oil tank comprises a tank body (1). An oil outlet pipe (2) and an oil inlet pipe (3) are arranged in the tank body (1), and communicated with an oil cylinder (6) through a reversing valve (5). The hydraulic safety oil tank further comprises an overflowing tank (31). The oil inlet pipe (3) is inserted into the overflowing tank (31), an annular overflowing disk (32) is fixedly arranged at the top end of the overflowing tank (31), and the height of the longitudinal position on the external circumference of the overflowing disk (32) is larger than the liquid level formed when the quantity of oil in the tank body (1) is largest. An exhaust device (33) is arranged on the bottom surface of the overflowing tank (31), the bottom end of the exhaust device (33) and the bottom surface of the overflowing tank (31) are connected in a sealed mode, the bottom end of the exhaust device (33) is communicated with an exhaust tank (36), and the exhaust tank (36) is communicated with a vacuum pump (4) located outside the tank body (1). The hydraulic safety oil tank can achieve rapid exhaust to guarantee the running safety of a hydraulic system.

Description

technical field [0001] The invention relates to an oil cylinder, in particular to an oil tank used in a hydraulic system that can improve the safety performance of the system operation. Background technique [0002] The hydraulic oil tank is a container used to store the oil required to ensure the operation of the hydraulic system. The main functions of the oil tank in the hydraulic system are: [0003] 1. Store the oil required for system circulation. [0004] 2. Dissipate the heat generated when the system works. [0005] 3. Release the gas mixed in the oil. [0006] 4. Provide a location for the installation of components in the system [0007] Among them, the release of gas mixed with oil is particularly important. The reason is that the presence of air bubbles in the oil can lead to cavitation, and what is more, the pressure of the air bubbles can cause damage to the system. [0008] The entry of air bubbles is caused by the air mixed in when the oil enters the po...
