Oil conveying hose with signal transmission function and preparing method of oil conveying hose

Abstract

The invention discloses an oil conveying hose with the signal transmission function and a preparing method of the oil conveying hose. The hose is used for conveying of coal oil in aviation and signaltransmission. The oil conveying hose comprises an inner protection layer used for oil conveying, a framework layer, a signal line and an outer protection layer are sequentially arranged outside the inner protection layer, the framework layer is used for supporting the signal line, the signal line is used for signal transmission. The oil conveying hose has the beneficial effects that the structureis simple, the hose is small in weight, the oil conveying hose is drawn out, springback is avoided, the service life is long, the oil adding amount signal can be transmitted in time, manpower calculation is not needed, and use is more convenient.

Description

technical field [0001] The invention belongs to the capability of transporting aviation kerosene and the function of transmitting data information, and further relates to an oil delivery hose with signal transmission function and a preparation method thereof. Background technique [0002] At present, the hose used for aircraft refueling is Ф63mm and the unit weight is 3.5kg / m. When unfolding and withdrawing this hose, it needs to be operated manually, which is labor-intensive. At the same time, it is not possible to transmit signals, and the fuel is used for metering pumps. Metering, unable to accurately and quickly refuel. [0003] The refueling hose in the prior art is placed on the reel. When refueling, 2-3 people are required to pull out the hose, and at the same time, 1 person is required to control the amount of refueling; such a hose is relatively heavy and inconvenient to use. The signal cannot be transmitted, and the amount of refueling cannot be accurately counted...

[0002] At present, the hose used for aircraft refueling is Ф63mm and the unit weight is 3.5kg / m. When unfolding and withdrawing this hose, it needs to be operated manually, which is labor-intensive.

[0003] The refueling hose in the prior art is placed on the reel. When refueling, 2-3 people are required to pull out the hose, and at the same time, 1 person is required to control the amount of refueling; such a hose is relatively heavy and inconvenient to use. It cannot transmit signals, and cannot accurately count the amount of refueling, which makes it very inconvenient to use

[0004] At the same time, in the prior art, the hose is affected by the tensile stress during the stretching process, and elastic deformation will occur, resulting in elongation of the hose, and after the tensile stress is eliminated, the hose will rebound due to the characteristics of rubber , causing the hose to be easily stretched and broken
