Is balance of rotor on the use of hydrostatic bearing pedestal, under the support embedded with a mirror. When there is no amount of unbalance rotor, by the light of beam after the mirror reflection, origin of the polar coordinates are projected into the unbalance indicator. If the rotor unbalance, rotor bearing in unbalance of heavy torque under the action of tilt, under the support of reflector is tilted and reflected light beam deflection, the beam into the origin of the polar point of light left indicator. According to the coordinates of points of light deflection, can get a rough measure of the size and location.
main performance of the use of residual unbalance, and unbalance decrement said two comprehensive indexes. The former is the balance function of residual unbalance rotor reached the minimum, it is one measure of this balancing machine the highest balance ability; The latter is the ratio of the amount of unbalance measured and the initial unbalance measured after a correction, which is a measure of the balance efficiency, generally expressed as a percentage.
In modern machinery, a flexible rotor balancing machine is developed due to the wide application of flexible rotor. This kind of balancing machine must be stepless speed adjustment within the rotor working speed range. Besides can measure the vibration of the bearing or vibration, also can measure the rotor deflection. Flexible rotor balancing machine
installed in a vacuum protective indoor, sometimes in order to suit the balance of such as steam turbine rotor, it is equipped with vacuum system, lubricating system, lubricating oil degassing system and data processing by computer system and other large auxiliary equipment.
With the use of microcomputer technology, the balance machine have brought in a new era, balancing machine in performance, accuracy and operability are improved significantly. And the fan, motor, electric tools, machinery manufacturing, paper making, textiles, household electrical appliances, metallurgy and other fields to get more and more widely used. The following will introduce you how to clean the Vertical Balancing Machines
Photoelectric head shots of the Vertical Balancing Machines
1. The glass should be used to clean lens paper or the outer surface of the clean cloth to wipe clean the mirror lens, keep clean, do not use cotton with oil or wiping the dirty cloth mirror. Balancing machine is a sophisticated detection equipment, there should be a special person is responsible for the warehousing and operation.
2. Often maintain the cleanness of balancing machine, Vertical Balancing Machines
guide surface should be clean, and should often besmear antirust oil. Vertical Balancing Machines bearing block or roller surface should be clean, no adhesion iron filings and dust sundry, before each work should be wiped clean bearing block or roller and rotor shaft neck, add a little oil.
3. Vertical Balancing Machines
supporting frame should be at the same time when the rotor rotation or move around supporting frame with speed at the same time, in order to avoid the shaft neck and wear of roller surface scratch is not allowed to put the rotor wheel rack to knock or hit. An imbalance of the rotor in the process of the rotation of the supporting structure and the rotor itself produces a stress, leading to vibration. Therefore, the rotor dynamic balance is a must.
