Centralised Lubrication systems by using progressive distributor block is a self-monitoring and reliable method against severe operating conditions. The Oil / Grease is metered and uniform irrespective of piping lengths. The progressive block consists of plunger moving to and fro in precision bore. The movement of the piston is governed by the oil flow. The lubrication point gets dosages of oil / grease in progressive manner. Indicator pin moves forward and backward after completion of one cycle. Any failure in the system can be sensed with the help of proximity switch.
The safety switch is either electrically connected in the series with the main motor starter or to a buzzer or Lub fault signal can be obtained and damages to the machine can be avoided by taking corrective action The system can be used as intermittent as well as continuous lubricating system by connecting return line to the reservoir.
The standard (One Piece) progressive blocks are available in 6, 8, 10, 12, 14 & 16 outlets. Special combined blocks are made available in 14,16,18,22 &24 outlets. The modular type progressive blocks is assembly of number of blocks. They are in two sizes 60 x 80 called Primary / Master Block second is 45 x 55 size called secondary progressive blocks. For each progressive block there is an indicator pin which operates once after completion of a cycle. And it helps to pin point from which block the oil supply has failed. The system can be restarted after taking corrective action.
