Who Is Progressive Maintenance Technologies?

PMT is an engineering and technical services company that specializes in plant reliability and maintenance improvement programs


Our mission
Our Mission

To assist companies in moving from a Cost Centered maintenance operation to a Profit Centered maintenance operation


A step in the right direction involves lubrication management
A Step In The Right DirectionInvolves Lubrication Management

“You Cannot Maintain Or Manage Equipment Without Maintaining And Managing Lubricants”


What is lubrication management
What Is Lubrication Management

Evaluation Process:

  • Review manufacturers lubrication recommendations/specifications

  • Evaluate each piece of equipment for both existing specifications and recommended performance specifications

  • Establish generic lubrication specifications based on equipment performance requirements

  • Establish lubrication PM program

  • Consolidate plant lubrication chemistries

  • Review equipment for proper filtration and breather applications

  • Establish oil analysis and contamination control program for applicable pieces of equipment

  • Evaluate storage and handling

  • Trouble shooting



Lubrication knowledge is important
Lubrication Knowledge Is Important

  • Understand Equipment Performance requirements

  • Understand Performance Characteristics Of Lubricants

  • Put them together


Easier said than done
Easier Said Than Done

OEM

Recommendations

Are Either Wrong, Inadequate

Or Outdated


Ashless anti wear additives
Ashless Anti-wear Additives

  • Are hydrolytically stable and resist degradation caused by water

  • Are ashless and therefore reduce deposits caused by additives

  • Provide protection against coast down wear and permit use in gas turbines

  • Make consolidation of lubricants easier

    • Turbine Oils

    • Hydraulic Oils (AW & R&O)

    • AGMA

    • AGMA EP (Meets FZG Specifications)

    • Compressor Oils

    • Meets “Non-Detergent” Recommendations



New raw materials and manufacturing techniques provide additional performance
New Raw Materials and Manufacturing Techniques Provide Additional Performance

  • Group II basestocks

  • Ashless anti-wear additive package

  • R & O only packages


Group ii basestocks
Group II Basestocks

  • Have inherently better oxidation resistance

  • Have better viscosity indexes

  • Have lower sulfur content


Synergistic anti oxidant blends
Synergistic Anti-oxidant Blends

  • Provide initial PVOT (RBOT) values for new turbine oils which are four to five times higher than older turbine oils or Group I turbine oils

  • Resists degradation – service life can easily quadruple compared to older turbine oils


Requires high cleanliness standards
Requires high cleanliness standards

  • Bulk loads should be manufactured and delivered at ISO 15/13/11 cleanliness levels

  • Dirty oil oxidizes more easily and produces more wear


Usage
USAGE

  • These chemistries are being field tested and have demonstrated excellent performance in both steam and gas turbines

  • Field data confirms that oxidation based degradation of the oil is significantly slower than older generation oils.


Lubrication concerns
Lubrication Concerns

  • Oil companies have made drastic formulation changes over the last 10 years

  • Oil historically used in hydro units no longer available

  • Additive technologies may be incompatible

  • Sludge formation when new oil added

  • Operational difficulties


Oil analysis concerns
Oil Analysis Concerns

  • Oil samples seldom show wear debris prior to failures

  • Bulk oil sample looks good , but sludge formation occurs

  • Unreliable or different sampling methods exist

  • No current method to ensure compatibility of new oil on top of old oil

  • Lack central database for trends and condition based maintenance

Deposit and Sludge Formation

Four Possible Reasons

  • Group II base oils do not hold varnish precursors in suspension as old generation group I base oils. These insolubles may form deposits.

  • The antioxidant precipitate as they are preferentially oxides causing the varnish.

  • The new generation antifoam additives have less effective short time domain air release characteristics and these small air bubble are adiabatically compressed causing the varnish

  • Cross-Contamination with Hydraulic Oil (AW)
