Riverhawk Going Green with Hydraulic Oil

Over the past several months, Riverhawk has been performing some extensive testing with a new environmentally safe hydraulic fluid. This potential new fluid is biodegradable and therefore much more environmentally friendly. We have undergone numerous test with this oil to make sure it is compatible with the components we use it in. To date, Riverhawk has completed testing evaluating the oils coefficient of friction, compatibility of being mixed with existing oil, effects on the different seal materials and different coatings. We have also tested its ability to mix with water. All the completed testing has gone well and we intend to replace our existing oil with this new environmentally safe oil in the coming months. We believe this change will be a welcomed improvement by many customers as environmental safety becomes a much more important topic in today’s world. More importantly, there is no cost impact to do this. If you have any thoughts or concerns with this change, please be sure to contact Riverhawk.

Riverhawk Product Spotlight – Hydraulic Torque Coupler (HTC)

The Riverhawk Hydraulic Torque Coupler (HTC) provides high integrity keyless fit joints for coupling hubs on shaft ends using convenient, low cost slip-fit designs. Our design eliminates heat at assembly as well as keys, splines, tapered shafts, plug/ring gauges and hydraulic maintenance equipment. Shaft ends are simplified therefore reducing design, manufacturing and maintenance costs. A coupling hub with an HTC can be easily repositioned anywhere on the shaft end during installation.

In addition to providing for new machinery designs, Riverhawk has also supplied HTC’s for retrofit and repair situations. If a standard interference fit hub slips often, damaging the rotor, or is very difficult to remove, or has to be cut off the shaft end, Riverhawk can offer a repair or upgrade using an HTC. We can provide higher slip torque by increasing interference, but at the same time making removal of the hub from the shaft easier. If you have any further questions about our Hydraulic Torque Coupler or think it would be useful in any of your applications, please feel free to contact our Engineering Department for any technical inquires or our Sales Department for a quote.

Product Overview: The Riverhawk Torque Blocker

The Riverhawk Torque Blocker is a mechanical fuse that can be installed in a drive train. When a torque overload occurs, the Torque Blocker will release and allow the driver and load equipment to coast down separately without damaging downstream equipment. A torque overload might be caused by short circuit conditions in an electric generator, running restart of electric motors, jams in rolling mills, or liquid slugs in compressors. Either way, the Torque Blocker will release at a preset torque value to protect your equipment. After a release occurs, the Torque Blocker can be reset quickly. An operator pumps up the hydraulic clamp, resets the mechanical pins, drains the oil, and the reset is complete. Although hydraulic pressure is used to set the unit, no hydraulic pressure is used during operation so there is no oil spray upon release.

Riverhawk Torque Blockers are well suited for applications that range from 14,000 to 5 million inch-pounds of torque. We are able to adapt to all kinds of shaft connections. Riverhawk can also provide a turnkey coupling and Torque Blocker combination by connecting our Torque Blocker to most any manufacturers flexible, rigid, or gear coupling.

Please take a moment to check out the animation on our website at the link below to see how a Torque Blocker works and contact Riverhawk Engineering with any questions you might have.

500N Series Vibration Monitoring Systems Development

Riverhawk has a large installed customer base of 500 Series Vibration Monitoring Systems. To better provide continued support to that base and address new opportunities, Riverhawk is developing a new vibration monitoring system designated as the 500N Series.

The updated racks will be 100% compatible with existing modules, while providing more efficient and modular power supplies and relay assemblies. The new modules will be 100% compatible with existing racks while providing improved performance and functionality. The new modules will include color LCD touch screens instead of the analog meters and switches. The LCDs will present more information and the touch screen will provide password protection for the set points and configuration information.

Like the older 500 Series, the new systems will be available in a panel mounted version with three 2” slots for two measuring modules and one control module. 19” rack mounted systems will accommodate six measuring modules and one control module. Each module can provide one or two channels for vibration or axial position monitoring. A variety of other modules will later be available.

Contact Riverhawk to discuss requirements to new applications, upgrading of existing systems, or spares.
