Metal seated ball valves for up to 420 bar and 450 °C

Monday, July 2nd, 2018 von admin

The patented design of the so-called ‘Dissolution’ ball valve offers optimized distribution of forces and loads in the ball valve, so that they only occur where they are actually needed. This means that the ball valve made by AS-Schneider can be actuated easily even under high pressures up to 420 bar.

The forces needed to maintain the tightness between ball seat and valve body are only directed onto the corresponding graphite seal rings (see figure).

Plug & Play sensor enables predictive gear unit maintenance

Monday, June 4th, 2018 von admin

Gear unit manufacturer Flender will be launching its new DX500 product with associated DX Assist app at the Achema show in Frankfurt am Main. The new smart sensor in the Diagnostex product series is a plug & play solution for measurement of vibrations and temperatures on the gear unit and notifies the system operator of irregularities by app straight to his smartphone or tablet. It enables the planning of predictive service work before unscheduled interruptions or stoppages of the production process can occur.

KSB puts pumps into the Internet of Things

Thursday, March 15th, 2018 von admin

At this year’s Achema, KSB is presenting a new pump monitoring system called KSB Guard. Networked vibration and temperature sensors fitted directly to the pump make availability at plant level transparent. The system ensures that changes in the operating behaviour of the machine are detected at an early stage, and maintenance work can be better planned, without having to be on site with the pump. Unlike previous systems, KSB Guard is ideally suited for retrofitting. The sensor unit is attached to the bearing bracket or the drive lantern of the pump using a magnet and adhesive, and can be mounted during operation, with no need for changes to the machine. A battery unit, which is also supplied, provides self-sufficient power supply.

Grundfos: Direct Sensors – the sense organs of the pump

Saturday, August 22nd, 2015 von admin

grundfos DirectYou can only change what is accessible by measurement – whoever wants to control a process flow of a pump needs reliable current data on the one hand, and on the other, possible intelligent linking and interpretation of this data: Sensors deliver data, microchips have stored software to interpret this and actuators implement the commands. To also offer technical benchmarks, the pump manufacturer Grundfos maintains well-equipped own research and development departments, finance and personnel dealing with motors, frequency converters, sensors, microchips and their programming.

The ‘Direct Sensor’ development is a micro-mechanical semiconductor sensor (MEMS, Micro-Electro-Mechanical System), which is produced in its own wafer fabrication facility of purity grade 10.
