Magnetic Filter Scrubber

Dzyanis May 4, 2020 1 Blogs filter

Just impressed how efficient can be Magnetic Filter Scrubber. I use it at all applications and photos below can explain why.

I mount these filters at the bottom of the tank downstream the butterfly shuttle valves (tank outlet ports). In case of service, these valves closing and checking/cleaning of scrubbers can be done without full oil drain from the tank. For that, each scrubber is provided with -04 orb port which lets to drain small qty of the hydraulic oil from the scrubber itself.

I’m not showing the brand of the scrubbers at the photo, this is not an advertisement of the specific brand, just wanna share the idea to use scrubbers, especially in the mobile applications, where the size of tanks usually not big enough to sedimentation of particles to the bottom of the tank.

How to select a hydraulic cooler

Dzyanis February 19, 2020 1 Blogs cooler, losses, pressure drop

At this article, I show my vision on how to:

determine the value of the heat needs to be rejected from the system;
calculate and select the right cooler size.

…and will provide an example of cooler calculation and selection.

What is a cooler and what is a heat exchanger?

The hydraulic cooler is one of the heat exchangers type. But, what is a heat exchanger? The best definition of the heat exchanger is:

Heat exchanger is a device that transfers heat between two fluids.

The simple sentence but a very good description, because fluids can be either oil, air, water, etc., and because transferred heat can be for either cooling or heating target.

There are two most popular types of heat exchangers in hydraulic systems:

Plate heat exchangers

Plate heat exchanger

This type has the best value of efficiency/reliability and designed for both cooling and heating applications and a very good for low-viscosity fluids. Pairs of plates can be removed individually for maintenance, cleaning, or replacement. Another advantage of the plate is exchangers is their low initial cost, as well as easy and inexpensive operation.

Fan radiators (air-cooled)

This type is the only option where water is unavailable or expensive for a delivery. From benefits: low maintenance and operating costs and the only option for oil cooling in mobile applications.

Fluid Power Reference Handbook review

Fluid Power Reference Handbook

This weekend I have received the first edition of the Fluid Power Reference Handbook from Fluid Power Society and in this article I would like to share my first impression about (my potential) ref-book for $75 USD.

Yes, I have paid $74.95 USD + 27.75 USD for delivery to Canada. If you are not a member of IFPS, the price for this handbook to be $99.95 USD. But if be honest, even $75 is pretty expensive for me. But I was assumed this book will be my table book for everyday usage and decided to spend so much money.

The book was delivered in a simple soft paper envelope and was damaged in its way, thanks to USPS and Canada Post. Actually, IFPS could send this book in a safe envelope with bubbles, but they didn’t do that, unfortunately. So, pages were crumpled and the back cover is with a scratch (the book has a softcover binding).

Anyways, it is what it is. Let’s take a look at what is inside of the book. And I’m going to compare this issue with my existing “Lightning Reference Handbook” (Eight Edition, 2001) that I was gotten from the vendor for FREE 6 years ago.

Fluid Power Reference Handbook consists of 20 chapters, 360 pages. Each chapter has own color with bookmarks at the side and it is really comfortable to search a targeted chapter. The paper is of pretty good quality and thickness what is good for everyday usage:

Danfoss to Acquire Eaton’s Hydraulics Business for $3.3 Billion

The poster of the week.

This is an important event that can change the balance of power in the hydraulics market.

The Danfoss Group announced today that it had reached an agreement with Eaton to acquire Eaton Hydraulics for $3.3 billion. Eaton Hydraulics serves agricultural, construction, and industrial markets and will be transferred into Danfoss Power Solutions. The transfer will add 11,000 employees to Danfoss, which currently employs 28,000 people. The deal is expected to close before the end of the year.
