  • Winter maintenance tips of vibratory pile driver

    The gear oil is replaced for the first time for about 10 hours, and for 100 hours at second time. If the weather is hot, you can replace gear oil 90 hours in advance. If the weather is cold, you can extend it to 130 hours to replace it.       The concentration of the gear oil should not be too high, it should be reduced as much as possible. ...

  • UNIPER Maasvlakte power plants - Case study

    Project Facts The UNIPER power plant, Maasvlakte (MPP3) is located adjacent to Rotterdam harbour on the North Sea coast and has a capacity of 1100 MW netto.

  • Flow Rate Measurement in Full Pipes Using the Transit Time Method

    Particularly in large diameters the relevance of water volume measurement is growing. The challenge with cooling water or fresh water processes is to generate accurate flow recordings or to document and to control individual consumptions and withdrawal quantities. Flow detection, however, particularly in large diameters is highly demanding. In such cases the transit time measurement thanks to its ...

  • Common Causes of Fish Kills in Your Pond

    What Killed My Fish? The first question everyone has when they notice fish floating in open water or washed up along the bank is: what killed my fish? The most common causes of fish kills are oxygen depletion, algal blooms (could deplete oxygen or be toxic), pesticide toxicity and disease. By far, the most common cause of fish kills is oxygen depletion in lakes or ...

  • The Power of the Moon

    The influence the moon has on life on earth is disputed. However, during an assignment in Southeast Asia, vibration experts from Sulzer were able to clearly confirm that the moon can even affect pumps. With its broad expertise, the Sulzer team was able to solve an unusual case of vibration. Southeast Asia is a key exporter of LNG (liquefied natural gas) to global markets, and it is ...

  • Ozone in Cooling Water Treatment

    When commercial ozone generators were first introduced for cooling water treatment, they were marketed as a stand-alone treatment, a cure-all or panacea. We now know this is not the case. Because there have been many misconceptions regarding ozone, this article is intended to review the basics of ozone, its true capabilities and limitations, and its potential benefits in cooling water treatment ...

  • Mild cleaning: removal of 900 kg iron from a cooling water system - within 7 hrs - Case Study

    A professional cooling water treatment prevents the plant from corrosion damages. But in case corrosion should occur, severe damages can be the consequence. The cooling system needs to be cleaned. In contrast to a conventional cleaning with aggressive acids, Kurita suggests an innovative cleaning method: mild, material-protective and effective.   With the mild Kurita cleaning method amazing ...
