Abstract

The invention relates to a totally closed hydraulic oil tank applied in a hydraulic circulatory system and taking hydraulic oil as circulatory hydraulic oil for use in a matching manner. The totally closed hydraulic oil tank includes an oil storage tank, an oil-gas separation device, an air filter, a return oil filter, a fuel charger, an oil level indicator, an oil outlet pipe and a flow guide device, wherein the volume of the oil-gas separation device is compacted and expanded to provide the space required for oil storage or oil supply of the hydraulic system, so that the hydraulic oil and air are in respective containers, pollution sources brought when air is breathed can be eliminated, the entire hydraulic system operates in a totally closed state, the hydraulic oil is controlled and prevented from pollution radically, the reliability and service lives of components can be effectively improved and prolonged, and further, the maintenance-free hydraulic system can be realized. The totally closed hydraulic oil tank is particularly suitable for dump trucks and loading trucks, and can be matched for use on various hydraulic systems under harsh environment.

Description

【Technical field】 [0001] The invention relates to a fully enclosed hydraulic oil tank for thoroughly controlling the contamination of hydraulic oil in a hydraulic system, in particular to a fully enclosed hydraulic oil tank used in conjunction with a dump truck, a loader and a hydraulic system in severe environmental pollution. 【Background technique】 [0002] The hydraulic oil tank is an oil supply and oil storage device for the hydraulic system. It needs to inhale air when supplying oil, and squeeze out air when storing oil. The breathing air and hydraulic oil are in the same container, resulting in pollution from the circulating air. Substances become the main source of pollution in the hydraulic system, especially in hydraulic systems that work in heavily polluted environments. The pollution of hydraulic oil is more serious. Due to the mixing of oil and gas, air bubbles are easily generated in the container to increase the volume, and overflow from the air filter after the...
