Abstract

The invention discloses an adjusting method for an opening diameter of an oil tank recirculation pipe. The adjusting method comprises the following steps that under the condition that oil can be induced at an opening of an oiling gun, an adjusting valve arranged in a recirculation pipe is adjusted for enlarging the opening diameter of the recirculation pipe, and adjustment for the adjusting valve for increasing the opening diameter is stopped until no oil can be induced at an opening of an oiling pipe to obtain the opening diameter of a ventilation hole of the recirculation pipe; or under the condition that no oil is induced at the opening of the oiling gun, the adjusting valve arranged in the recirculation pipe is adjusted for reducing the opening diameter of the recirculation pipe, the adjusting valve arranged in the recirculation pipe is adjusted again for enlarging the opening diameter of the recirculation pipe until oil can be induced at the opening of the oiling pipe, and adjustment for the adjusting valve for increasing the opening diameter is stopped until no oil can be induced at the opening of the oiling pipe to obtain the opening diameter of the ventilation hole of the recirculation pipe. The adjusting method solves the problem of different demands of the opening diameter of the recirculation pipe in the prior art, and realizes optimal adjustment of the opening diameter.

Description

technical field [0001] The invention relates to the automatic adjustment of the hole diameter of the recirculation pipe of the fuel tank, in particular, to a method for adjusting the hole diameter of the recirculation pipe of the fuel tank. Background technique [0002] The fuel tank is a fuel container on an airplane or a car, and it is a special container for storing hydraulic oil or hydraulic fluid in a hydraulic system. Fuel tanks can be divided into open fuel tanks and closed fuel tanks. The oil tank must have a large enough volume; the oil suction pipe and the oil return pipe should be inserted below the minimum liquid level to prevent air suction and return oil splashing to produce air bubbles; the distance between the oil suction pipe and the oil return pipe should be as far as possible, and the distance between them should be Set up partitions; in order to keep the oil clean, the oil tank should have a peripherally sealed cover plate with an air filter installed on...
