Vibration analysis on optical laser

The Good the Bad and the Wrong One of our clients was experiencing trouble with unacceptable levels of vibration seen at optical laser used for laser interferometer. This problem was confounded by the additional requirement of a more stringent specification requirement on entering a new market. DC White were brought on board as design partners to develop a solution which would work in the new market [...]

SPP Pumps – Vibration Analysis

Vibration Analysis For SPP Industrial Water Pumps SPP Pumps produce industrial water pumps for use all over the world. Systems may use diesel engines or electric motors, and can be long vertical turbine "water-lift" pumps or conventional horizontal centrifugal pumps. We provide lateral or torsional critical speed analysis to mitigate pump vibration along with substantiation for structural steel-work such as base-plates and enclosures. We have experience meeting the [...]

Failure Analysis

Heat Exchanger failure

Heat Exchanger failure - DC White were called in to investigate a calorifier (heat exchanger) in a cheese factory which had exploded during use. Fortunately there had been no injuries. The calorifier supplied hot water for cleaning dairy equipment but had exploded taking out the wall of the building in which it was sited. The unit had been recently checked and signed off by the licensing authorities. [...]

Bespoke Modelling on a Re-boiler – Chemical Plant

Thermal analysis – bespoke modelling This case study describes an analysis performed earlier this year on a Heavy-End re-boiler, which was identified with a potential thermal transient problem. The heat exchanger is normally used for heating a flow of hazardous liquor with a pressurised steam flow. The vessel is a horizontal cylinder with 2 dished ends which create end plenums, capped by 2 tube-sheets 9m apart. [...]

Impact Study: Vibration Station

Impact Analysis of Plaster & Glass Fibre Tamper Machine DC White have a wealth of experience from many impact analysis projects across a number of industries. These have included Power Stations, Nuclear Fuel Rods and the manufacturing project detailed below. We were asked to investigate the mysterious failures occurring repeatedly in a machine which tamped a mix of plaster and glass fibre into a mould used to [...]
