Description

Technical Field

[0001] The utility model relates to the technical field of fixed limiting devices, in particular to a fixed limiting device for a metal oil tank. Background Art

[0002] Fuel tanks can be divided into open and closed types. The tank must have a sufficiently large capacity. The suction and return lines should be inserted below the minimum liquid level to prevent air bubbles from cavitation and return oil splashing. The suction and return lines should be as far apart as possible, with a partition between them. To keep the oil clean, the tank should have a sealed cover with an air filter installed. The bottom of the tank should be at least 150 mm above the ground. Pay close attention to the anti-corrosion treatment of the inner surface of the tank.
