Why You Should Include Oil Analysis in Your Preventative Maintenance Program

Posted by Dustin Flynn on Thu, Jan. 04, 2018

Accessing a System that is Currently in Place

Preventative maintenance is a program put in place in most manufacturing or production industries to ensure quality scheduled maintenance is provided. Maintenance professionals implement these routine inspections before, during and after the operation of machinery. Parts of this routine can include areas that can only be inspected by touch, not sight, to determine what is happening under the surface. 

Oil analysis can be added to this routine maintenance to give a fuller picture of whats happening inside machinery and equipment. By including oil analysis in a preventative maintenance program, maintenance professionals are provided with detailed inside information that could prevent issues in the future, like unexpected downtime.

Paper Mill Lube Filter Element Upgrade

Posted by Jim Harlan on Tue, Jul. 25, 2017

 

The Application

Large paper mills rely on continuous production to be profitable, thus unplanned down time is a huge financial burden. When unplanned downtime does occur and equipment must also be either repaired or replaced, the damages can feel exponential.

DFE Rated Filter Doubles Element Life, Cuts Contamination Levels in Half

Posted by Jim Harlan on Wed, Jun. 07, 2017

The Problem

A paper machine was experiencing excessive down time as maintenance personnel was frequently servicing a Brand X filter element installed on the lube system. The element would reach terminal ∆P and require replacement every 8.5 days on average.

When a Pump Fails, the Whole System Fails: Hydraulic Pump Reliability

Posted by Jim Harlan on Tue, Feb. 21, 2017

The Problem: Hydraulic Pump Failure 

Pumps are the heart of hydraulic systems. When the pump fails, the entire system is down until the pump is operational again. This poses a serious threat to any operation relying on hydraulic systems for productivity.

Recently, a hydraulic valve manufacturer was losing 25 pumps a year on their centralized hydraulic system at a cost of $2,440 each -- and that’s only the pump cost. When you account for maintenance resources, lost oil and lost production, each failure costs ~$25,320.

Hy-Pro vs. Brand X Filters in a Single-Pass Fluid Transfer

Posted by Jim Harlan on Tue, Feb. 07, 2017

The Problem

Today’s oil suppliers are often required to provide fluid at or below a specified ISO Cleanliness Code. One such supplier was experiencing short filter element life (15 days) on the system (7 element multi-round housing) used to achieve the required ISO Cleanliness Code of 18/16/13 in a single pass as 15W-40 oil is transferred from their bulk storage tanks to tanker trucks for delivery.

High Surface Finish Defects at an Automotive Stamping Plant

Posted by Jim Harlan on Tue, Jan. 03, 2017

The Application

An automotive stamping plant operating large presses to produce body panels was experiencing high surface finish defect scrap. Lubricating oil contamination was causing surface imperfections that would be visible after painting.

The Problem

The uncoiler/washer lube oil system was protected by an off-line filtration system fitted with CJC stacked disc cellulose media filter inserts (elements). Oil analysis revealed an operating ISO code of 23/19/11. Patch analysis showed cellulose fibers were shedding into the oil from the filter inserts downstream of the filtration system.

An Aluminum Refinery Faces Premature Gearbox Oil Changes

Posted by Jim Harlan on Wed, Dec. 14, 2016

The Application

An Australian aluminum refinery was consistently performing premature gearbox lube oil changes on seven base drive units due to oil and particulate contamination.

With an average operating ISO code of 20/18/16 and average water levels of 4742ppm, the 360 liters / 90 gallons of ISO VG320 gear oil was being changed far too often. Cost per gearbox oil change (excluding crane, lost production, labor) is $17,962.60 which adds up to $125,738.20 for all seven units.

Hydraulic Valve Performance Test Stands and Clean Oil

Posted by Jim Harlan on Tue, Nov. 29, 2016

The Application

A hydraulic valve manufacturer required pristine fluid (< 14/12/9) to test flow across an 80-micron orifice on their test stand. Gross amounts of contamination in the fluid would skew the test results, invalidating any data collected.

The system held 100 l (26.4 gal ) of ISO VG 32 fluid with a flow rate of 25 lpm (6.6 gpm ).Through observing the manufacturer’s sampling practices, discussing fluid handling best practices and interpreting their lab reports, three independent problems were identified:

[Video] Your Lab Reports Are Probably Wrong -- Here's How To Save Them

Posted by Scott Howard on Tue, Aug. 16, 2016
When looking at a lab report, it is assumed the information on the report is accurate. A certified lab will not usually make an error in the report, but if so, it is obvious and easily fixed. Ever hear the saying "By the time the lab gets the report the error has already been made"? For the most part, this is true. Where people are led off course is believing the particle count on the lab report is the gospel. This is natural, but unfortunately not always the case with a bottle sample unless you already employ the techniques listed in the video below.

Vacuum Dehydrator Called On to Save Fishing Season

Posted by Jim Harlan on Fri, Apr. 15, 2016

One of our V1S vacuum dehydrators was recently put to the test in a marine application with hydraulic oil contaminated by more than 2500 ppm of water. Did it sink or swim? Find out below.

The Problem: Failed Hydraulics Seal and Lost Productivity

When a seal fails on a net hauler hydraulics system out at sea, the costs and lost profits stack up quickly. In this instance, salt water began entering the hydraulic fluid on a 245 ft (75 m) purse seine through a seal leak, rendering the net hauler out of commission.

Faced with frequent fluid exchanges at a cost of $9,300 plus disposal, or worse, substantially larger lost profits from downtime for replacement of the seal, the vessel owner was in desperate need for a solution to allow him to continue operating without fear of malfunctioning equipment.
