Problems solved by technology
[0002] The Aircraft Spoiler Power Control Unit (PCU) is an electro-hydraulic servo-actuated component. After the repair work is completed, the entire component needs to be tested for function, although most of the tests are for its mechanical properties, such as travel, internal leakage , withstand voltage, hysteresis and other tests, but these tests require the input of various control electrical signals, and demodulate the feedback signal of the sensor of the component. These tests are inseparable from the special test equipment that is matched with the component. , the existing test equipment is the equipment provided by the PCU manufacturer. This equipment is expensive and not sold externally. It is only provided to major airline customers as incidental equipment and is only used for their internal maintenance, or it is only provided to the manufacturer. Self-established maintenance units, ordinary maintenance companies may not be able to obtain this equipment because it may cause competition in the industry. At the same time, this equipment is a special equipment with limited functions. Different types of test equipment need to be purchased for different types of components. For domestic maintenance companies It is said that the cost is too high to afford; current aircraft spoiler power control components generally have a relatively uniform test socket for testing
