Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of hydraulic oil tanks, and particularly relates to a hydraulic oil tank which is beneficial to heat dissipation. Background Art
[0002] In a hydraulic system, an oil tank is an essential oil storage device. Currently, the vast majority of hydraulic systems use open-type oil tanks. An open-type oil tank means that the liquid level in the oil tank is in direct contact with the air. Its working principle is that when the oil level in the oil tank rises, the air above the oil level is discharged into the atmosphere through the vent; when the oil level drops, the atmosphere enters the oil tank through the vent. However, since the oil level of the open-type oil tank is in direct contact with the gas mixed with dust and water vapor, it not only accelerates the oxidation and deterioration rate of the hydraulic oil, but also increases the failure rate caused by excessive oil contamination.
[0003] For the existing hydraulic oil tank devices on the market, on the premise of ensuring the normal functions of taking and discharging hydraulic oil, their positions are not specifically set. In the existing technology, during the process of repeatedly taking the internal hydraulic oil, heat may accumulate inside. When the internal heat exceeds the threshold, there is a high probability of serious safety hazards. For this reason, we propose a hydraulic oil tank which is beneficial to heat dissipation.
