Product Description

High speed balancing and overspeed test facility  (PHW-2000)

 

Production Description

1) Special designed brackets can effectively transmit mechanical force
2) The durable and reliable sensor possesses high sensitivity
3) The permanent calibration brings high accuracy
4) Driven by universal coupling,transmit the power steadily
5) Applicable to rotors which can't be driven by belt or need large power
6) Advanced electrical measuring system and friendly man-machine interface

 

Range of Application

 

Jp has been engaged in the development and design of High speed balancing and overspeed test facility for heavy turbine and generator rotors as well as for high-speed compressors of steam and gas turbines .Use special bearing pedestals equipped with isotropically supported bearings, providing equal stiffness in all bearing plane radial directions, and are suitable for use at extremely high balancing and test speeds 

 

 

Explosion proof enclosure

 

To protect the surroundings from the dangers resulting from a total or partial explosion of the rotor, a variety of different solutions can be recommended

Longstanding experience has shown that a walk-in tunnel design is most suitable, especially for medium or large facilitiesFor rotors weighing up to 8 t, with outer diameters up to 1.7 m, an axially sliding vacuum chamber with integrated burst protection can be used

 

Drive system

 

For high-speed balancing, overspeed testing and dynamic straightening of flexible rotors, either a  motor with frequency converter or an infinitely variable motor with thyristor control can be used .

Depending on the required speed range, a suitable transmission gear has to be installed. A so-called intermediate shaft constitutes the connection between the gear and the over-speed testing chamber. Rotors are coupled to this intermediate shaft by means of precision drive shafts.

Measuring system
 

 The measuring unit employs JP-580 Electrical Measuring unit is a system of top function and precision. It can be applied in all kinds of single/double plate and hard/soft bearing machines, and can be connected with different velocity and pressure sensors easily. The unit adopts industrial computer made in Yanxiang Industry Co, which equiped with 17-inch LCD screen and Windows XP Operating System. Featuring with high running speed and reliabilitystrong dustproof and shakeproof ability, it is applicable to various industrial environments.
