Problems solved by technology

[0002] There are a large number of hydraulic components on the aircraft. These hydraulic components must be tested for the performance of the hydraulic components before they are installed. Some of them require high-temperature oil to pass through the hydraulic components, so the oil entering the hydraulic components needs to be heated. There are three hydraulic oil heating methods: overflow heating, oil tank heating, pipeline aluminum ingot heating, etc. The existing oil heating methods have disadvantages such as difficult control of temperature accuracy, unstable heating rate, carbonization of the oil, and easy deterioration of the oil.

Abstract

The invention relates to a method for providing a heated hydraulic fluid for a hydraulic component test. A hydraulic pipeline connected with a hydraulic component and a hydraulic oil tank are involved, a liquid heating device is involved, the body of the liquid heating device is an aluminum ingot, electric heating pipes are arranged in the aluminum ingot, a curved liquid passage is also formed inthe aluminum ingot, and a first temperature sensor is arranged on the surface of the aluminum ingot body of the liquid heating device; the liquid heating device is circularly communicated with the hydraulic component and the hydraulic oil tank through the hydraulic pipeline, the hydraulic pipeline between the liquid heating device and the hydraulic component is divided into a first branch and a second branch through a reversing valve, the first branch passes through the hydraulic component and then enters the hydraulic oil tank, and the second branch is directly communicated with the hydraulicoil tank. A second temperature sensor is disposed between the liquid heating device and the reversing valve.
