Vibration Analysis and Field Dynamic Balance KMbalancer II is a full-featured, high-performance dual channel FFT vibration analysis and field dynamic balance. It can be applied in the field of equipment condition monitoring in many industries, such as paper industry, petrochemical industry, machinery manufacturing, etc. KMbalancer II can collect various field data, such as vibration values, bearing status, spectral graphs and time domain waveforms, and can further integrate and analyze equipment faults through KMVS Pro data acquisition and analysis software.
There are several thrust tiles on the working face and non-working face on both sides of the thrust disk installed on the main shaft. There is a pin hole on the back of the tile of the field dynamic balance instrument. The tile is placed on the pin of the mounting ring by this hole, and the tile can rotate slightly around the pin.
The pin hole on the tile is set at a deviation of 7.54mm, and the field dynamic balancer therefore forms a wedge gap between the working face of the tile and the thrust disk. When the thrust disk rotates, the oil is squeezed in the wedge clearance, and the pressure is increased, so the oil film has the ability to withstand the axial thrust of the rotor. The mounting ring is arranged on the spherical seat, and the oil is connected to the thrust bearing oil inlet chamber through the throttle hole, which is divided into two ways and enters the annular oil chamber around the spindle through the oil inlet hole on the spherical seat of the thrust bearing, and flows radially between the tiles.
There is a spacious hole between the tile and the tile to facilitate the circulation of oil in the tile. The thrust bearing spherical seat is equipped with an oil return ring, and the oil ring of the dynamic balance instrument is enclosed in the outer circle of the thrust disk to form a ring oil return chamber. Two oil return holes are arranged on the top of the oil return stop ring of the working face and the non-working face respectively, and the amount of oil return can be adjusted by a needle valve.
An oil retaining ring is also arranged between the mounting ring of the thrust pad and the thrust disc. The oil retaining ring encloses the thrust pad and forms the annular oil inlet chamber of the thrust bearing.
