Description

Technical Field

[0001] The invention relates to the technical field of oil tank oil circuit heating devices, in particular to an oil tank oil circuit heating device and a heating method. Background Art

[0002] The fuel container on an airplane or a car is a special container for storing hydraulic oil or hydraulic fluid in a hydraulic system. The oil tank can be divided into two types: open oil tank and closed oil tank. 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 bubbles from being generated by suction and oil return splashing; the distance between the oil suction pipe and the oil return pipe should be as far as possible, and a partition should be set between them; in order to keep the oil clean, the oil tank should have a peripheral sealed cover with an air filter installed on the cover; the bottom of the oil tank should be more than 150mm from the ground; full attention should be paid to the anti-corrosion treatment of the inner surface of the oil tank;

[0003] Through the connection between the fuel injection nozzle and the fuel inlet pipe, when the electromagnetic coil is energized, suction is generated, the needle valve is sucked up, the spray hole is opened, and the fuel is sprayed out at high speed through the annular gap between the needle at the head of the needle valve and the spray hole, forming a mist, which is conducive to full combustion. In the past, the fuel injection nozzle used in diesel engines was mechanically controlled. The mechanical diesel nozzle works by controlling precision parts (needle valve, needle valve body).

[0004] The existing oil inlet pipe does not use a preheating mechanism. When gasoline enters the oil pipe, the oil inlet pipe needs to be heated by the heated gasoline, which consumes a lot of time in the preheating process, resulting in a technical problem of too long preheating time.
