Technical Paper: How to – Vibration Analysis

Wednesday, August 1st, 2018 von admin

Fig. 1 Analyzing vibration measurements on Omnitrend Center taken by Vibscanner 2.

It’s not a secret, that vibration on machines causes severe issues – not only on a long term perspective. Vibration, caused by any issue is the natural enemy of any rotating machine such as a pump. Due to the latest handheld high-speed data collector Vibscanner by Pruftechnik vibration of all kind on all kind of machine can be detected during the maintenance routine.

With the special software Omnitrend Center the measurement results of Vibscanner 2 (Fig. 1) can be analyzed deeply and used for an entire machine health program. But what measurements does the new high-speed data collector Vibscanner 2 deliver, how do you interpret these and how can you react on these measurements? Let us give you a quick kick-start into vibration analysis to help keep your pumps alive.

Technical Paper: High-performance carbon – the service life extender for pumps

Thursday, July 19th, 2018 von admin

Slides assume the main job of generating the vacuum – more than 30,000 hours of durability were achieved using a new material

Whether slide bearings, sliders or mechanical seals – all these components are exposed to high loads on a daily basis and, therefore, wear out. With innovative materials, however, maintenance intervals and the service life of pumps and seals can be extended considerably, as evidenced by developments in carbon materials.

Selecting the right material determines the service life of machines, units, and systems. Conventional materials often reach their load capacity limits, especially in pumps and mechanical seals. Schunk Carbon Technology develops and produces materials for seal rings, slide bearings, and pump components made of carbon and silicon carbide. These innovative materials particularly excel in the areas of abrasion resistance, sliding capability, media resistance, and temperature resistance. Carbon in the form of graphite also has the characteristic property of self-lubrication. All in all, exactly the features required in demanding industrial environments. “In practice, their use leads to a significant increase in service life and extended service intervals,” says Thomas Kräuter, Sales Director of the Mechanical Carbon Industry at Schunk. It is not enough to simply replace a material; many years of expertise are required. Three current development projects demonstrate the path from material to functioning components, leading to new materials that considerably extend the service life of pumps, seals and the like.

The generation of maintainers who check the condition of pumps on a daily basis by listening and touching the equipment is dying out. Nevertheless, pumps must operate reliably. To solve this problem, BestSens has developed the Bearing Monitoring System, BeMoS for short (Figure 1).

BeMoS monitors roller bearings in machinery and plants from the very first second of operation. What is so special about it is the underlying technology:

Inpro: Bearing Isolator for Pumps

Tuesday, March 7th, 2017 von admin

The Bearing Isolator extends bearing life by increasing protection against contamination ingress and lubrication loss. The original Bearing Isolator, a simple two-piece design, consisted of a rotor and stator interface to keep contaminants from entering the bearing housing. Now, the next generation of Bearing Isolators has been presented.

The VB45-S Bearing Isolator utilizes a patented XX Interface coupled with an enlarged contamination chamber to achieve an IP66 rating, the standard for ingress protection against both harmful dust particulates and powerful water jets from all directions. For superior protection against lubrication loss, the VB45-S utilizes an enlarged D-Groove to capture oil and return it back to the bearing housing or a grease band to block grease from traveling down the shaft and escaping from the bearing housing.

Durit: Increasing wear protection, reducing maintenance costs

Thursday, June 25th, 2015 von admin

DuritImage_2015_04Pumping of abrasive slurry or chemical reagents demand for maximum efficiency and work pace increasing wear of the applied components and thus all associated maintenance costs in pump technology as well. More and more frequently, seal and packing rings of pumps are made of ttungsten carbide – a sinter material. Additional fields of application for tungsten carbide components in pump engineering include

  • rotors,
  • control elements,
  • bearing sleeves,
  • plain bearings,
  • and hubs,

which are exposed to abrasive media.

Waukesha: Tilt pad thrust bearings for up to 300 °C

Tuesday, October 14th, 2014 von admin

WB_HidraxHTThe new Hidrax™ HT thrust bearings are developed for high-temperature applications in electric submersible pumps. These pad bearings can sustain unit loads of 8 MPa (1160 psi) at oil bath temperatures up to 300°C (572°F).

Technological advances in steam-assisted gravity drainage are increasing operating temperatures and placing increased demands on the thrust bearings located in the motor seal/protector section of the electric submersible pumps string.
