PRODUCTS & SERVICES 25 The damaged rotor was sent


to Sulzer’s service centre in Rotterdam, which is equipped with specialist facilities for remanufacturing rotors. Here, a new stage-two impeller was manufactured along with new labyrinth seals and sleeves, while the remaining impellers were refurbished. Meanwhile, a new diaphragm for stage two was manufactured and installed in the Leeds facility. Dale Jarvis, business development


engineer for turbomachinery at Leeds, comments: “During the communications with the client, our engineers recommended that the bearings in the gearbox should also be checked for damage following the original failure. Since this drivetrain was already out of operation, the client agreed and the subsequent inspection highlighted a need to replace the bearings. By looking at the bigger picture we were able to deliver a more reliable solution without


adding to the overall downtime of the project.” Having completed the rebuild of the compressor, the field services team together with the client’s maintenance team reinstalled it, which completed the commissioning. In all, the repair was completed in eight weeks, a time frame that had been agreed with the client at the start of the project; the refurbished compressor now has a significantly increased service life.


As a result of this project, further


work will be carried out on similar compressor drivetrains in the same area, with special attention being paid to the gearbox bearings which may be reaching the end of their service lives.

New testing product launches for Emtech at PaperCon


New product launches and a number of well-known testing systems aimed at the wet and dry ends of paper, board and tissue production lines are being showcased by Emtec Electronic at PaperCon, being held in the US from 23-26 April at Minneapolis. Systems for measuring materials


throughout the manufacturing process, from pulp to the final product, will be exhibited on the booth of Technidyne, which is


Germany-based Emtec’s US sales partner. In the wet end, the new AFG


touch! units are said to help to optimise the dosage of chemicals and stabilise the production process, thus controlling the quality of the final product. In particular, says Emtech, the new FPA touch! Fiber Potential Analyzer and CAS touch! Charge Analyzing System for measurement of the zeta


potential of fibres and the particle charge in pulp suspensions are first-time introductions to the visitors of the PaperCon. Also on show will be the TSA Tissue Softness Analyzer that determines the three single parameters of the softness (real softness, smoothness, stiffness) and the automatically computes Hand Feel value.


When issues such as glueability,


printability and coatability occur in the converting of paper and board, and their origin is


unknown, the EST12 Surface & Sizing Tester or the modular system PDA.C02 Penetration Dynamics Analyzer can help to solve these issues by the determination of the surface parameters – surface sizing and surface porosity. These are of real importance for the converting process, says Emtech. More information from Emtec Electronic GmbH, Gorkistrasse 31, 04347 Leipzig, Germany.
