Here we are going to discuss on lubrication of vacuum pump and the topics we are going to cover here is:
1) Why lubrication
2) Factors that affect Lube oil
3) Selecting the right oil
4) Challenges faced
Whether your Company is producing simple bolts, complex Gears or high precision Valves, keeping your machinery running efficiently is the Key to your profitability.
The same logic applies to your Vacuum Pumps. After all in any machine the active physical interrelationship taking place in the equipment requires that your Lubricant works together effectively your slide-way oil must work seamlessly.
A good Vacuum Pump Oil must have good and stable viscosity over a wide temperature range stable Vapour Pressure even at High Temperature and excellent slide-way Lubricating properties. The oils must also be resistive to Moisture or other Aggressive Vapours.
In any Machine or Vacuum Pump, mixing oil or solvents with the Lubricant is unavoidable. In some case the oil may not separate and thus get contaminated. This contaminated oil will compromise the effectiveness of the working fluid by shortening the life and poor performance. Excessive contamination can also lead to foul odour and potential employees' health and safety concerns,
To avoid these issues and help ensures that your equipment runs smoothly over a long haul, choose a high performance Lubricant that is specifically designed to deliver excellent frictional properties across a wide range of applications.
Oxidation: Caused when churning oil foams exposing more oil to surface air causing oxidation that lowers viscosity.
Dilution: Caused when the Lubricant oil is diluted with gases, dropping viscosity.
Contamination: Vapours from Hydrocarbons being processed can mix with oils, changing viscosity.
Temperature changes: Typically at start up, significant changes in temperature can occur that affect the viscosity along with contaminants, aggravating the change in viscosity.
Poor lubricant can result to loss of Vacuum, bearing failure which in turn 'cause wear on the Rotor assembly.
To avoid any unpredictable failure and loss of revenue more often than monthly Lubricating Oil checks is needed to prevent plant downtime. Preventative approach is an ideal way to ensure unscheduled downtime.
Effective Lubrication should always begin with the specifications of the best product for the job. Operators should select a Lubricant that is not only of the highest quality, but one that has been formulated to enhance equipment performance for the specific application.
Without a clear focus on the essential role played by effective Lubrication in maximizing uptime, operators may opt for a lower quality grade Lubricant which will ultimately prove costly. This in turn has a detrimental impact on the Brand reputation and customer relationship, as production deadlines are missed.
Component wear and reduced component life can quickly occur if the Lubricant is not performing properly, because it is not of sufficient quality for this specialist application, is not being applied properly or has been contaminated.
Oil and Grease analysis plays a vital role in minimizing component wear and down time.
What are the challenges that effective Lubrication need to address to ensure smooth running. The challenge are Two fold, combining issues relating to operation requirements, including load. The Lubricant need to be able to resist contamination and remain equally effective under varied operating conditions.
The core purpose of the Lubricant is to keep metal surfaces apart and its ability to do this effectively is dependent on the film thickness between components.
'This can alter according to the different variables such as:
Effect on film thickness
Film thickness increases as viscosity increases.
Viscosity decreases (film as thickness) temperature Increases
Film thickness decreases as load increases.
Film thickness decreases as speed increases.
