Description

TECHNICAL FIELD

[0001] The utility model belongs to alcohol ester production technical field, more particularly in oil tank for engineering machinery with protection structure. BACKGROUND

[0002] The oil tank for engineering machinery is a special container for storing hydraulic oil or hydraulic fluid in a hydraulic system.

It is one of the important components to ensure the normal operation of the engineering machinery vehicle.

[0003] The material of the oil tank is various, including metal (such as aluminum alloy, stainless steel, iron, etc.) and plastic (such as PE, rotational molding, etc.). Different materials of the oil tank have advantages and disadvantages in terms of corrosion resistance, weight, cost, etc. The volume of the oil tank should be large enough to meet the driving range and heat dissipation requirements of the engineering machinery. At the same time, the volume of the oil tank should be reasonably matched according to the model and power of the engineering machinery. The oil tank cover and the oil tank body of the engineering machinery on the market are generally connected by threads. Although this connection method is convenient for quick opening and closing in daily operation, it also has safety hazards: because it makes the oil tank cover relatively easy to be opened by unauthorized personnel. Once a criminal intends to steal the fuel inside the oil tank, this simple connection method will provide convenience for them, thereby greatly increasing the risk of oil tank theft, not only bringing inconvenience to the normal operation of the engineering machinery, but also possibly causing economic losses and adversely affecting the overall structure and service life of the oil tank.
