The traditional instrument for measuring liquid level, oil temperature, oil pressure and flow is changed into a sensor, and a liquid crystal display screen is added, so that the working state parameters of the hydraulic station are clear at a glance, but the working environment of part of hydraulic systems is very bad. For example, a hydraulic system for a solar sun tracking device is often installed in areas such as gobi deserts and deserts with harsh natural environments. The day and night temperature difference of the areas is large (can reach 50 ℃), and much dust is generated; hydraulic systems for comminution for environmental protection devices are often installed in dusty places. In addition, some hydraulic systems operate in environments that contain gases that can deteriorate the hydraulic oil. Meanwhile, since the volume of hydraulic oil increases or decreases with a change in temperature, the entire apparatus must be equipped with a buffer tank capable of accommodating the change in volume of hydraulic oil. Conventional surge tanks employ a fixed volume vessel. In order to ensure stable pressure in the buffer tank, the hydraulic oil needs to be communicated with the atmosphere when the volume is increased or reduced. When the environment is stably raised, the volume of hydraulic oil is increased, and partial gas in the buffer tank needs to be discharged; when the ambient temperature decreases, the volume of the hydraulic oil increases, and a certain amount of gas needs to be sucked into the buffer tank. The buffer tank sucks in gas and inevitably contains dust, moisture or impurities which deteriorate hydraulic oil, so that the operation of a hydraulic oil circulating system is seriously damaged.
The conventional hydraulic system adopts a filter additionally arranged at the suction/exhaust port of the buffer tank, but the filter has limited service life and can only filter dust, so that harmful gas and water vapor cannot be isolated. If the adsorbent such as active carbon is adopted, the cost is high, and the change of the content of harmful components in the environment is large, the replacement period is not fixed, the maintenance is difficult, and the failure is easy.
