CAMA (Luoyang) Electromechanic Co., Ltd (Original named Nanfeng), affiliated with China Airborne Missile Academy, is the biggest and leading engine test bench manufacturer in China.
CAMA exclusively introduced eddy current dynamometer technology from Germany ZOLLNER GMBH in 1988. With military manufacturing history of fifty-year, advantage of quality control system in airborne enterprise, CAMA successfully sold about 5000 engine test benches to more than 800 customers all over the world.
Series CW eddy current dynamometers, which produced by our company and manufactured according to the proprietary techniques of ZOLLNER GMBH in Germany, have advantages of low inertia, high accuracy and stability, simple structure, convenient maintenance, complete series, wide use, automation in operation and control etc.
The dynamometers are not only used for testing and performance test of engine but also in the fields of performance test, survivability test, model test of other prime mover, dynamo, rotational system and some components and parts like oil pump, oil nozzle, speed governor and so on. They are widely used in production, scientific research, education, maintenance and other fields.
CAMA develops constantly, not only serializes of types, but also designs, produces and installs complete test-bed of dynamometer for customers. With high technology, integrated engineering strength and rich experience, NF company can produce high-level testing equipments to serve customers sincerely.
Nowadays CAMA eddy current dynamometers hold over 85% market share in China, products are exported to America, Australia, Russia, Turkey, Malaysia, Vietnam, Laos, etc. About 5, 000 sets of CAMA eddy current dynos are running in CAMA's more than 800 customers' company.
Key technical indexes of the eddy current dynamometer:
Measurement accuracy of the torque of the system is better than ± 0.2%FSR
Measurement Sensitivity of the torque is better than ± 0.1%FSR
Measurement error of the rotation speed is less than± 0.1%FSR ± 1 digit
Structure Features and Safety Protection Function:
A. Indirect dry cooling gap structure: To prevent rotors from being corroded by water and negative influence on measurement accuracy caused by friction between cooling water and rotor.
B. Unique drum type rotor disk: Effectively lower rotor rotating inertia.
C. Reliable thin oil lubrication system: To guarantee sufficient lubrication and cooling of high-speed bearings and prolong dynamometer service life.
D. Perfect safety alarm devices: Including speed alarm, emergency stop alarm, inlet water pressure alarm, outlet water temperature alarm, ring over-temperature alarm, insufficient lubrication oil alarm, over-speed alarm, etc, which adequately protect dynamometer.
