What is the need of Oil Analysis ?

Oil is the lifeline for machines & equipment’s. Just like routine blood check up for humans gives an idea about the health of a person, analysis of oil at regular intervals gives an idea about the health of the equipment or machine from time to time.

We cannot really look into our equipment’s, a very successful & proven way of looking what has been happening inside our Equipments is through Oil analysis. Oil analysis gives appropriate information about what has been happening inside the equipment’s.

Chem-TechTM Laboratories Oil analysis programs monitors Equipments for Mechanical, Operational, Environmental and other Factors which are bound to affect lubricants health and condition. Degradation of Oil properties might result in heavy losses due to maintenance and costly down time.

Benefits of Oil Analysis

Oil analysis for a number of years has been used as an integral tool for monitoring the condition of the Equipment’s & Machines.

Following are few of the benefits:

  • Provides accurate information of the condition of the equipment and machines.
  • Gives information and idea of what has been exactly happening inside your Machines and Equipments.
  • Very useful in Predictive maintenance Programs of the Equipments.
  • Reduces costly downtime by giving alarms regarding Malfunctioning of Equipments.
  • Reduces Millions of Rupees in Maintenance and Downtime Costs.
  • Monitoring failure of the instrument.
  • Extend Oil Drain Levels.
  • Increase functionality of the Equipment and maximize reliability.
What Oil Analysis can tell ?
  • Condition of the Oil & further serviceability of oil
  • Machine Condition
  • Amount & Type of Wearing of components
  • Amount of External contaminants in Oil like Water, Dirt, Dust, Debris Etc.
  • Amount of physical & chemical degradation of oil
  • Overall Machine and Equipment performance

Note: Other Tests may included in the Oil Analysis Program depending on the need of the oil analysis program for the customer.

Designing an Oil Condition Monitoring or Predictive Maintenance Program
  • Chem-TechTM assists in designing an oil condition monitoring program that will suit the customer and the equipment depending upon its application and use.
  • Once the tests and interval of the oil sampling are decided the customer can send the samples directly to the laboratory for analysis. Typical turnaround time for Testing of the oil samples is usually 48- 72 hrs.
  • Once the results are obtained from the laboratory, the condition and the wearing pattern of the equipment’s can be analysed from the trend analysis report.
Important Factors to be considered for implementing oil analysis Programs
  • Tests to beconduced are samples are decided initially which might depend on the Industry and environmental factors.
  • Sampling Point should be decided and each time sample should be drawn from the same point to ensure repetitive results and draw appropriate conclusions from the oil analysis data.
  • Deciding the sampling frequency of the Equipments depending on the application, its criticality and surrounding environmental conditions.
  • Using clean sampling bottles for oil sampling.
  • Drawing representative samples.
