Hydraulic Valve Performance Test Stands & 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; 3 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.

Fluid Analysis Reference Guide

Posted by Jim Harlan on Tue, May. 10, 2016

Do you have trouble translating your fluid analysis reports into useful information you can act upon? If you were to notice high levels of Ba on your report would you know what it is and where its likely coming from? If you could use a hand we’ve got the perfect tool in our new Fluid Analysis Reference Guide.

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.

Contamination Tool - Mobile App

Posted by Jim Harlan on Thu, Feb. 04, 2016

Have you downloaded our mobile app?

The Hy-Pro Filtration Contamination Tool is now available for download on your iPhone or Android.

What can you do with the app?

  1. Calculate the amount of contamination passing through system components annually by specifying current flow rate, daily hours of operation and ISO fluid cleanliness code.

Filter Sizing: Calculating Clean Element Dp

Posted by Jim Harlan on Wed, Nov. 19, 2014

Choosing the best filter element size and media for a specific application can be tricky. You want media that is tight enough to help you reach your target ISO code. However, if you choose a media that is too tight for your application; the element Dp will rise too quickly and you will be replacing elements far too frequently. To prevent these situations you should always calculate clean element Dp whenever changing filter media or manufacturer.
