Constant Level Oiler

In many oil lubricated machines it is essential to maintain a constant level of oil to properly lubricate machine elements in motion. Excessive oil level increases resistance resulting in higher oil temperature. This causes faster ageing and breakage of oil seals, which means frequent oil leakages. Low oil level is a sure recipe for equipment failure.


Generally a constant level of oil is required wherever 'SPLASH' Lubrication is used. Splashing would occur if part of rotating element is in oil and part is above the oil. Generally it is 1/3 to 1/2 the bottom rolling aliment Ref. Fig. 1


Lubex JOINTLESS DESIGN CLO with view glass has the advantage of zero leakage since there are no joints. THE VIEW GLASS PROVIDES ON LINE VISUAL INDICATION OF OIL LEVEL IN THE SUMP AND ALLOWS TO VISUALLY INSPECT QUALITY OF OIL.


The PC/GLASS dome is threaded and can be cleaned periodically if required. The entire design is totally modular, thus any individual component of the oiler can be replaced at any point of time.


The working principle of 'LUBEX' constant level oiler is extremely simple. As and when oil level falls below level 'x' air passage is opened, you will notice bubbling taking place within PC dome. Oil flows from PC/GLASS dome in to the machine causing oil level to rise within the machine. The moment oil level in the equipment reaches level 'x' air passage is blocked bubbling stops and oil from PC / GLASS dome stops going into the machine. Ref. fig .2


Thus oil in PC/GLASS dome goes on decreasing, but oil within the machine is maintained at a constant level. Oil can be recharged in PC/GLASS dome at any point of time by simply unscrewing base and refilling PC/GLASS dome with an oil can. Ref. fig.3. The product is designed and manufactured to last for several years, an excellent investment for oil lubricated machines requiring a constant level of oil.

Lubex Adjustable Height Oil Cup With Pc Dome

In this design of constant level oiler the height of the cup can be adjusted upward /downward depending on the level of oil required in the bearing housing.

The oil level to be adjusted is generally 1/3 to ½ the bottom rolling element of the bearing. Ref. Fig. 1. The level can be adjusted by opening the cup & taking wing nuts up-down, once height is adjusted the wing nuts are locked. Each time you fill oil in the cup and slide it on the holder wing nuts act like a stopper, moreover the base is secured to the holder by tightening thimble, this ensures that the oil cup does not move up during operation. Old oil can be drained out periodically by opening drain plug.

The advantage of Lubex oil cups is that dome is made of Polycarbonate and threaded. Polycarbonate has excellent impact strength (Virtually unbreakable) good temp stability – i.e. 120°C. Moreover since dome is threaded to base it can be replaced. These oilers are available with glass dome metal cage also.

Constant Level Oiler in Closed Loop System

BREATHER PLUGS
SIMPLE VENT

SHIELDED BREATHER PLUGS

In any pump wherein a constant level oiler (CLO) is installed there is a vent plug (breather plug) either with a vent on the side or bottom. Ref fig.1(a). 1(b). When the pump rotates there is splashing within the oil chamber (ref. Fig 2). This constant Churning of oil at high speed causes an oil/AIR MIST within the oil chamber , which is released trough the vent. However there is always a risk that external contaminants like MOISTURE, FINE SUSPENDED PARTICLES IN THE AIR, FINE DUST etc. could enter in the oil chamber through the vent, THUS CONTAMINATING THE OIL.

There is always a higher risk of this happening in STAND- BY PUMPS since there is NO INTERNAL PRESSURE WITHIN THE OIL CHAMBER CONTAMINATED OIL REDUCES THE LIFE OF BEARINGS SUBSTANTIALLY. Lubex CLO in closed Loop solves this problem considerably. The vent is replaced by a bushing (generally ½” X ¼”BSP). A PU COMPRESSION fitting with 6mm O.D. PU Tube is fitted in place of the vent plug. The other end of the PU tubing is fixed to the PU COMPRESSION fitting in holder of oiler. This forms a closed loop, wherein the oil AIR MIST comes back to the oiler ref. fig. 3. There is very little chance of external contaminants entering into the oil chamber. This system decreases the FREQUENCY OF OIL CHANGE, REDUCES CONTAMINATION OF OIL AND THUS SIGNIFICANTLY INCREASES LIFE OF BEARINGS. Major Refineries and Petrochemicals plants internationally already have introduced these kinds of devices on their pumps.

In a few Refineries /Petrochemicals plants they now have an AIR HEADER through which low pressure DRY Lubricated compressed Air is provided to the pump. This totally eliminates Ingress of any contaminant entering through the air passage slots in the oiler. Ref. Fig. 4(a) & Fig. 4(b). This arrangement is not in our scope of supply. THE GOAL IS TO HAVE ENHANCED LIFE OF BEARINGS AND REDUCED FREQUENCY OF OIL CHANGE. SKF and other leading bearing manufacturers are guaranteeing 7-8 years of LIFE. Where are you?

Constant Level Oiler

In many oil lubricated machines it is essential to maintain a constant level of oil to properly lubricate machine elements in motion. Excessive oil level increases resistance resulting in higher oil temperatur This causes faster ageing and breakage of oil seals, which means frequent oil leakages. Low oil level is a sure recipe for equipment failure.


Generally a constant level of oil is required wherever 'SPLASH' lubrication technique is employed. In this system of lubrication rotating element causes a 'splash' due to its rotation and this splashed lubricant in turn lubricates all other machine elements within the system. Splashing would occur if part of rotating element is in oil and part is above the oil. Rf. Fig.1


The right answer is to install an efficient, reliable constant level oiler. 'LUBEX' constant level oiler consists of a polycarbonate (PC) dome with suitable aluminium alloy base and elbow to fit your equipment. PC has the advantage of extraordinary impact strength (virtually unbreakable), excellent clarity, and good temperature range (110 ° c). A lock nut facilitates keeping the oiler upright without overtightening elbow.


The PC dome is threaded and can be cleaned periodically if required. The entire design is totally modular, thus any individual component of the oiler can be replaced at any point of time.


The working principle of 'LUBEX' constant level oiler is extremely simple. As and when oil level falls below level 'x' air passage is opened, you will notice bubbling taking place within PC dome. Oil flows from PC dome into the machine causing oil level to rise within the machine. The moment oil level in the equipment reaches level 'x' air passage is blocked bubbling stops and oil from PC dome stops going into the machine. Ref. fig.2


Thus oil in PC dome goes on decreasing, but oil within the machine is maintained at a constant level. Oil can be recharged in PC dome at any point of time by simply unscrewing base and refilling PC dome with an oil can. The product is designed and manufactured to last for several years, an excellent investment for oil lubricated machines requiring a constant level of oil.

Tech. Comparison (CLO)

The importance of reliable (CLO)

  • Any of Lubricated machine especially centrifugal has a CLO.
  • The oil level in the Sump should be 1/3rd to 1/2 the bottom ball Ref Fig. 1
  • If oil level in not 1/2 to 1/3rd splashing will not take place Ref. Fig. 2 (a) 2(b)
  • Assume ball diameter is 6mm, this means if oil level goes below or up by 2mm splashing will not take place.
  • If splaashing does not take place upper balls do not get lubricated, hence bearing fails prematurely Ref. Fig. 2(a), 2(b).
  • Conventional hinge type oilers have the follwing problems Ref. Fig. 4 (a), (b), (c)

  • Leakages from elbow From slit Ref. Fig. 3(a)
  • Breakage from ear of elbow while tilting to fill oil Ref. Fig. 4(a)
  • Breakage of elbow while tilting CLO in pump Ref. Fig. 4 (b)
  • Difficulty in filling oil, the cup turns only 100 to 110 °C oil spillage Ref. Fig. (5)

  • Threaded polycarbonate (PC) dome. PC has excellent clarity, high impact strength. Dome is replaceble.
  • breakage are almost NIL.
  • Lock Nut facility in elbow to prevent overtightening
  • Filling oil is easy Ref. Fig 6(A). No spillage of oil.
  • Breathing is through slots in base, No chance of leakage from holder. Ref. Fig 6.
  • Lubex CLO solves all problems of conventional CLO. Once installed expected LIFE is 4/5 years.
