In recent years, with the development of the domestic aviation industry and changes in the international environment, the demand for testing domestic aviation power has become increasingly high. Based on the characteristics of the industry, Liance Technology has developed a series of high-speed and ultra high speed hydraulic dynamometer products on the basis of professional production of hydraulic dynamometers. Through a series of scientific research and development processes such as 3D design, simulation analysis, and product testing verification, the developed high-speed hydraulic dynamometer products are compared with international brands.
Main technical features:
Compact structure, high rigidity of the whole machine, strong seismic resistance;
Strengthening heat treatment and surface flame spraying treatment of special materials for stator and rotor, with strong resistance to gas corrosion;
High stiffness support for tilting pad bearings;
The spindle rotor undergoes high-precision dynamic balancing, with low inertia and high-speed operation characteristics;
The whole machine has high machining accuracy, meeting the high-speed operation requirements of aviation precision bearings;
Adopting oil spray lubrication to meet the lubrication requirements of aviation high-speed bearings;
Adopting tight sealing and carbon sealing technology, there is no oil-water crossover or leakage under high-speed and high-pressure working conditions;
High speed response servo control for inlet and outlet water;
High speed data acquisition, multi parameter security monitoring and alarm unit
