Leading Manufacturer, Supplier & Retailer of Metering Cartridges and Metering Cartridge.
in single shot centralised lubrication system, amount of oil at each lubrication point is controlled by using the element known as metering cartridge.
for each lubrication point at least one metering cartridge shall be used.
the metering cartridge is a kind of mini-cylinder with a check valve, where stroke of piston determines the amount of ejected oil. It is designed such that every time when pump is operated, it ejects out predetermined amount of oil. When pressure is released, the cartridge gets recharged. For proper recharging of metering cartridges there shall be a small time gap in between subsequent operations of pumps (min. 1 minute).
maximum permissible pressure for metering cartridge is 40 kg/cm2. Minimum working pressure is 8 kg/cm2and pressure shall drop to less than 1 kg/cm2in between successive operations.
guide lines for dose selection
1) dose of metering cartridge to a particular point shall be determined as per following procedure.
calculate equivalent area as per below :
a) plain bearings :
a = d l
d = shaft diameter
l = length of bearing
b) gears :
a = d x w
d = pitch diameter of gear
w = width of gear
c) large bull gears :
a = 2 d x w
d = pitch diameter of pinion
w = width of pinion gear
d) worm gears :
a = (d1 + d2) w
d1 = pitch diameter of worm
d2 = pitch diameter of worm gear
w = width of worm gear
2) select metering cartridge as per the following table:
common applications
metering cartridges are used in single shot oil lubrication system on various machines such as machine tools, textile machines, die casting machines, sheet metal working machines, shearing and press brakes, metal forming machines, rubber mixing machines, printing machines, injection/blow moulding machines, presses and hammers, packaging equipment, pharmaceuticals machines, food processing equipment etc.
