Abstract
The utility model relates to a totally closed hydraulic oil tank matched with circulating hydraulic oil in use. The oil tank comprises an oil storage tank, an oil-gas separating device, an air filter, an oil return filter, an oil filler, an oil outlet pipe and a guide device. The oil storage tank stores or supplies oil to a hydraulic system through air bag compression and expanded volume. One end of the guide tube is connected with the oil filter, while the other end of the guide tube is connected with the guide device. The oil filler is an independent oil filling device, and an oiling cylinder is blocked by a large plug and is welded with the oil storage tank. When the volume of hydraulic oil in the oil storage tank is increased during oil storage or the volume of hydraulic oil is decreased during oil supply, the air bag discharges air to reduce the volume or inflates to expand the volume through the air filter. The oil tank provided by the utility model can avoid pollution caused by hydraulic oil inflating air, so that the whole hydraulic system operates in a totally closed state and the hydraulic oil is thoroughly prevented from being polluted so as to improve the service life and reliability of hydraulic components, therefore, the hydraulic system is free from maintenance. The oil tank is in particular suitable for dumpers, carriers and various hydraulic systems in severe environments.
