3. Application

Aerospace field

During the R&D and testing phases of aircraft engines, the Bently Nevada 330180-91-00 is used to monitor vibration, displacement, and speed of the engine rotor shaft. Aircraft engines are pieces of highly complex and highly precise equipment and various parameters need to be accurately measured during the test process. The sensor can accurately obtain the vibration data of the shaft when the engine runs at a high speed, which assists engineers in analyzing rotor engine balance, bearing working condition, etc., thus providing key data support for optimization design and performance improvement, assuring reliability and safety of aircraft engines in flight.

Bently Nevada 330180-91-00 monitors the operating condition of the turbine shaft system, whereas the actual work will be done only when the engine is Mathured and dispatched after maintenance. It helps the engines to compare against some standard data, indicating whether or not the repaired engines developed comply with design attribute requests, and whether the shaft systems are fitted rightly. Thus, ensuring that the repaired engine is in good condition to be used normally and reduce the risk of flight accidents resulting from maintenance-related quality failures.

Automobile manufacturing industry

Bently Nevada 330180-91-00 is used for random checks on shaft vibration and speed of the finished engine that complete the inspection link of the automobile engine assembly period. The quality of automobile engines directly reflects on the performance and reliability of the entire vehicle. Bently Nevada 330180-91-00 assesses the shaft vibrations and speed to determine any assembly quality problems, such as clearance discrepancies between the piston and the cylinder or crankshaft imbalance. If any abnormal site detected, it is probable to adjust or repair such engine  timely in order to avoid the poor-quality ones on the market, thereby improving car overall quality, as also their brand images.

Bently 330180-91-00 is used in automobile transmission endurance test equipment to monitor the transmission shaft vibration and displacement. From the data of long-term durability tests of the transmission, Bently 330180-91-00 can analyze vibrations and displacements of the shaft. It will know the status of wear of the internal gears of the transmission, the longevity of the bearings, and so forth. Therefore, it offers a reference for transmission design optimization and quality enhancement, assurance of reliability and durability of vehicles under actual usage, and upgrading users' quality satisfaction with automobile products.
