Embodiment Construction

[0018] The present invention will be further described below in conjunction with drawings and embodiments.

[0019] Such as figure 1 , The main hydraulic pump of the electrical system adopts the YZB-23C aviation hydraulic pump with a small size and a rated speed of 4200r / min. The speed of ordinary motors is generally around 3000r / min, which requires a speed regulating device to regulate the speed. The general methods of speed regulation include gear speed regulation, frequency conversion speed regulation and coupling speed regulation. Gear speed regulation, due to the mechanical structure, cannot be changed; the cost of the coupling is high, and the speed regulation process is complicated; the frequency converter can realize smooth stepless speed regulation, high speed regulation efficiency, and is convenient for computer control. Therefore, the speed regulating device adopts the FRN45G1lS-4CX frequency converter with dynamic torque vector control, and the motor adopts a hig...

Abstract

The invention discloses a high-pressure hydraulic pump truck control system for aircrafts. The control system is composed of an electrical system and a computer control system. The control system with the functions of real-time monitoring, self-protecting, automatic alarming and the like is designed by adopting the variable-frequency speed regulation and computer control technology, the functions of a hydraulic pump truck are enriched, and the guarantee efficiency and the automatic level of the hydraulic pump truck are improved. The control system works well, the operation difficulty of the hydraulic pump truck is lowered, the performance, the functions and the automation degree of the hydraulic pump truck are improved, and the guarantee efficiency is improved.

Description

[0001] Technical field [0002] The invention relates to a control system of an aircraft high-pressure hydraulic pump vehicle, which is suitable for the mechanical field. Background technique [0003] The aviation hydraulic hydraulic pump truck is an important aviation ground support equipment, which is responsible for the inspection and debugging of the aircraft hydraulic system on the ground. The control system is the core of the hydraulic pump truck, and its technical level determines the quality and efficiency of the hydraulic pump truck to complete the task, and affects the level of aircraft maintenance. In the past, hydraulic pump trucks were mostly operated manually, with single functions and low automation level. In order to improve the support capability of the hydraulic pump truck, a control system with real-time status monitoring, self-protection, automatic alarm and other functions was designed, which greatly improved the support efficiency and maintenance level o...
