VUD Prevents Bearing Failure & Unplanned Outage

Posted by Jim Harlan on Tue, May. 16, 2017

Saves >$15,000,000 by removing water and particulate from common reservoir lube oil.

The Application

In boiler water feed pump applications, water often finds its way into the oil lubricating the pump’s bearings. This was the scenario at a paper manufacturing facility that turned to Hy-Pro for help.

The Problem

In this application, the boiler water feed pump bearing lube system was combined with the facility’s steam turbine lube oil system. The water, and the particulate contamination it was bringing with it, were decreasing the fluid’s ability to lubricate the bearings and causing premature wear on the bearings. The facility was attempting to remove free water with water absorbing filters (changed weekly) but the rate of ingression was too high for the filters to be as effective as needed. And since absorbents only remove free water, the filter elements were unable to address the dissolved and emulsified water present in the oil.If the situation were to continue much longer, a premature replacement of the steam turbine and boiler feed pump bearings would be necessary outside of the scheduled maintenance periods. While possible, this solution would cost millions of dollars without addressing the root of the problem.

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. Sink or swim? Find out below.

The Problem- When a seal fails on your net hauler hydraulics 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 seiner through a seal leak, rendering the net hauler out of commission. Faced with frequent fluid exchanges at a cost of $9300 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.

Conditioning New Oil

Posted by Jim Harlan on Fri, Feb. 19, 2016

Subpar fluid handling practices and inadequate filtration are the leading cause behind system reliability issues today. Contaminated hydraulic fluids foul valves and other components causing them to eventually fail and bring your production process to a screeching halt. This also happens when contamination within lube oils damages the system components the fluid is meant to protect. Your hydraulic fluids and lube oils are the lifeblood of your systems, and on a larger scale your entire operation, so they should be cared for as a precious resource from reception to disposal. One of the best ways to reduce contamination in your system is to prevent it from ever entering it in the first place so let’s discuss the best practices for receiving and storing new fluids.

Phosphate Ester Acid Remediation

Posted by Scott Howard on Mon, Jan. 20, 2014

Phosphate ester hydraulic fluid has the tendency to become very acidic. As we’ve discussed previously, this acid can cause damage to seals throughout out the system and lead to electrokinetic wear (and failure) in valves.

What is a Vacuum Dehydrator?

Posted by Scott Howard on Mon, Sep. 30, 2013

If the hydraulic, lubricating, compressor, or gear oil you use is not water base in formulation, then water is considered a contaminant and must be recognized and managed.  There are three types of water in a typical system; free water, emulsified water, and dissolved water.  Most oils' water saturation point, that point above which water is in a free form, is 200-400ppm, depending on age and condition. Using 100ppm for an upper water limit for most systems using mineral base oils, this means all free & emulsified water and a significant portion of dissolved water must be removed.  A vacuum dehydrator is one of the very few methods to remove dissolved water from oil.  Let's take a look at these three types of water in your system. It will give you a solid foundation for how the vacuum dehydrator works in the end.

The Ins and Outs of Water Contamination

Posted by Jim Harlan on Mon, Aug. 19, 2013

Moisture contamination is inherent in the world we live in. In fact, it's all around us. Humidity is the level of water vapor in the atmosphere. If there is 80% humidity, the air contains 80% of the total amount of water vapor it can hold at the given temperature. Thus, there's always an amount of water in the air.
