Allweiler Supplies Heaviest Lubricating Modules for Hitachi

11.09.2006

Babcock-Hitachi Europe GmbH (BHE) is expanding its two Hungarian brown-coal and gas power stations, Matra and Nyiregyhaza, with a total of three Hitachi gas turbine systems. The Plant Construction Division of Allweiler AG is to supply the lubricating oil plants for all of the turbines.

Allweiler Supplies Heaviest Lubricating Modules for Hitachi

Allweiler will install these modules ready-for-use, complete with gearbox, torque converter and starter motor. Allweiler centrifugal pumps will be used to pump the lubricating oil. With an empty weight of around 85 t, the plants are the heaviest that Allweiler has built to date.

The lubricating oil plants, as gearbox package, connect the gas turbines to the generators. They are completely constructed and assembled by Allweiler. In addition to the gearboxes supplied by Hitachi, the complete electrical and control systems are also included. In each module, three centrifugal pumps in the NSSV series pump the lubricating oil from the 10,000 l tank. The pump capacity of each of these pumps is up to 1,000 l/min.

"We won this order for two fundamental reasons," says Stefan Kleinmann, Plant Construction Director at Allweiler. "Firstly, because we have already supplied many similar plants for other turbine manufacturers, the second decisive factor was that we have already worked with Hitachi on the development of the new H-25AX turbine in Situ in Japan." The order value is around one million Euro. The last module left the factory in August 2006, around six months after order placement.

Lubricating oil plants are part of the core business of the Plant Construction Division of Allweiler AG. Johann Engelmann, Plant Sales and Service Director: "Optimal coordination of components and many years of experience are very important. With our specialists and manufacturing techniques, we can guarantee both of these factors."

The lubricating oil modules supply the turbines, gearbox and generators with lubricating oil, which filters, ventilates and cools the plant continuously and automatically. Lubricating oil modules are VIC components ("very important components") in power stations, as their reliable operation is essential for safe and continuous power generation. A breakdown would result in damages running into millions.

Installation of 320 Ovarro remote correlating loggers has taken place in Davao City in the Philippines, with a major leak detected just days later. The volume of water saved means a large-scale project to construct a new production well can be put on hold. Davao is the largest city on the island of Mindanao and the third largest in the Philippines. With a rapidly increasing population, the city is considered one of the country’s fastest economic growth areas.

EMW Pump Reduces Maintenance Needs by Three Quarters

12.02.2024 -

After years of changing new casings and propellers every three months to their process pump, a metal industry operator switched their worn-out pump to one of Sulzer’s EMW slurry pumps at their melt shop. The client considered the change a leap forward in their slurry pumping technology since the maintenance interval grew significantly, pump efficiency improved, and the change reduced power consumption.

Condensate Pumps Retrofitted by Sulzer Offer Fourfold Improvement in MTBF

05.02.2024 -

Operators of offshore platforms are very focused on the reliability of their equipment. Working in such a remote location means that major repairs, if not carefully planned, can result in extended downtime and loss of production. For one platform in Malaysia, a change in output was shortly followed by an increased rate of seal failures on the condensate pumps – an issue that was effectively resolved with a Sulzer retrofit, through their OEM-X line service.
