Special Design For You
For the newly built hulls, the propeller most fit to the aim special to you is designed through computer supported engineering calculations, following the filling of the form covering the measurements of the hull and the features of the machinery by the customer or our representative equipped with the required technical knowledge. It is either cast with a mold from our stock of about one thousand models or by the preparation of a new model of mold.
Modification
Modification is holding your propeller subject to a process according to the measurements found following the calculation of the physical measurements of your present propeller. This can be lowering the cycle, reducing the pitch for the propellers producing black smoke, reducing the diameter or reducing the proportion of the propeller area.
The pitch has to be raised for the high cycled propellers which cannot produce the expected and calculated speed. Further, it is possible for the problems of the propellers producing noise to be solved. Following the processes, the propellers are dynamically balanced.
Maintenance & Repair
In GÜRMARÄ°N PERVANE repairs at an unrecognizable level for the propeller to appear as original are realized by the application of the TÄ°G and MÄ°G welding techniques where the proper filling wires fit to the original material of the propeller are used. Following the repairs, a report is issued about the condition of the propeller.
Dynamic Balance of Propellers
In the manufacture and maintenance of propellers, the removal of imbalance bears as much importance as physical precision. Although the final static balances of the propellers are provided prior to their final polishing, this is not usually sufficient at high cycles and for the hulls where sensitivity is expected.
In case the imbalance of the propellers are attempted to be removed by the firms dealing with dynamic balance, the derangement of the geometrical measurements is in subject due to their lack of information about the geometry of the propellers. Thus, this would lead to the imbalance of the water forces when the propeller is used in water. Therefore, bigger problems would arise while a single defect is tried to be removed.
