LUBRICATION OF RING FRAME MOTORS IN TEXTILE SPINNING

Given the fact that ring frame motors contribute around 45% to power consumption in spinning mills, an incremental efficiency of the motor performance would imply huge savings for the users. As such, Klüber Lubrication’s new product offers excellent benefits

The optimal operation of bearings in a ring frame motor is very critical for the successful operation of any textile spinning mill. Poor lubrication of these bearings would not only result in the stoppage of the ring frames but could also reduce the efficiency of the ring frames during continuous operation. As the ring frame motors contribute to around 45% power consumption in spinning mills, an incremental efficiency of the motor performance would imply huge savings for the users.

Optimal lubrication of 4th generation machines with spindlage of more than 1,632 (1,632-1,824 spindles) has also been a challenge for the industry in the past. Improper lubrication of the ring frame motor can add various other challenges for users such as:

  • Re-lubrication without removal of machine would lead to grease entering the motor armature, resulting in high probability of motor failure. Resulting rewinding of coils could also cause reduction in motor efficiency by 4.5% to 5.0%.
  • Due to the location of the main motor, removal of the ring frame main motor would result in machine stoppage for more than five hours, resulting in huge production loss.
  • Poor lubrication would result in additional noise from the motor.
  • Frequent re-lubrication also adds to higher manpower costs and operating costs.

Commonly used lubricants in the past were supposed to be re-lubricated once every 3-4 months. During this period, users faced issues like grease oxidation and grease blackening.

The Klüberquiet BQH 72-102 Solution

With more than 90 years of experience in developing and manufacturing specialty lubricants, experts at Klüber Lubrication set out to find a permanent solution for this growing challenge from the Indian market. The solution was attained with the product Klüberquiet BQH 72-102. This low-noise and high-performance grease was also developed to solve challenges related to the lubrication of ring frame motors. A key advantage of Klüberquiet BQH 72-102 is that it does not degenerate with electrical discharge, which is a common occurrence in motor bearings.

The high-speed and temperature resistance property of the grease also ensures that phenomena like oxidation and blackening of the grease are completely eliminated. Extensive tests which lasted for more than two years were initially carried out at three different spinning mills in India. At these user locations, the product Klüberquiet BQH 72-102 showed reduction in temperature of more than 10 degrees Celsius which  directly co-relates to increased efficiency of the ring frame motor operation.

Another huge benefit for the user was the increased re-lubrication interval attained by Klüberquiet BQH 72-102. The lubricant was able to increase the re-lubrication interval from 3-4 months’ interval to an astounding 1.5 years’ re-lubrication interval. But naturally, users were very happy with the results achieved as problems like production stoppage for re-lubrication, probability of the grease seeping into the armature coil and reduced efficiency were completely eliminated. The high-speed ‘quiet’ operation property of the lubricant is also an additional feature which was well-appreciated by users during the extensive trials.

Excellent condition of motor bearings after 1.5 years of operation with Klüberquiet BQH 72-102

Commenting on the advantages of Klüberquiet BQH 72-102, Pramod Almore, Head (Textiles), Klüber Lubrication India (P) Ltd., says, “It really gives great satisfaction to see a delighted customer who has come out from the perennial problem of motor-bearing lubrication. The continuous increase in the number of companies opting for Klüberquiet BQH 72-102 is irrefutable evidence of the success of this unprecedented revolutionary solution. The customer not only gets higher performance but also saves more than Rs 1 million in operating costs.”

Benefits at a Glance

  • Longer re-lubrication interval of about 1.5 years.
  • Higher efficiency of operation due to reduction in operating temperatures of the ring frames’ motor bearings.
  • Lesser initial torque and lower noise.
  • Cleaner motor armature due to lesser re-lubrication.
  • No electrical erosion in the bearings.
  • Lesser operating and manpower costs.
  • Improved electrical conductivity for motors equipped with inverters.
