Aircraft ground lubricating oil pressure refueling device

Abstract

An aircraft ground lubricating oil pressure refueling device relates to ground equipment structure design in the technical field of aviation. The device is used for aircraft refueling. The device comprises a hand pump provided with two duct interfaces, and the two duct interfaces are respectively communicated with a ground oil tank and an oil distributing valve through ducts. A first oil filter, a one-way valve, a second oil filter and a ground oil path mouth are sequentially arranged downstream of the duct of the path of the oil distributing valve. The second oil filter and the ground oil path mouth are connected by a hose. According to the aircraft ground lubricating oil pressure refueling device provided by the invention, the refueling efficiency is improved, the oil quality of aircraft refueling is ensured, and guarantee is provided for improving the working reliability and security of the system, prolonging the service life of the accessories and ensuring the flight safety.

Description

technical field [0001] The invention relates to the structural design of ground equipment in the field of aviation technology, in particular to an aircraft ground lubricating oil pressure refueling device. Background technique [0002] Aircraft refueling methods are divided into two types: gravity refueling and pressure refueling. Gravity refueling is to use the oil's own gravity to refuel. The refueling cap is generally opened on the fuselage. When refueling, the cap needs to be opened. The refueling equipment is simple, but there are the following deficiencies : [0003] (1) The refueling time is long, the efficiency is low, and the labor intensity of the maintenance personnel is high; [0004] (2) The mouth cover is opened on the upper part of the aircraft. When refueling, a ladder is required to climb up the aircraft to refuel. The maneuverability is poor, and it is easy to cause unsafe factors and other deficiencies, and the reliability is low; [0005] (3) In the ope...
