Rota Deniz Üssü’nde jet türbinlerinin maksimum hassasiyetle pozisyonlandırılması

İspanya’da endüstriyel proseslerin otomasyonu alanında faaliyet gösteren Fluidmec-anica Sur şirketi, Omron Electronics Spain ile işbirliği yaparak, İspanya’nın Rota şehrindeki deniz üssünde Harrier jet türbinlerini tersanenin girişinden atölyeye taşıyan vinç için ileri seviyeli bir kontrol sistemi geliştirmiştir.

Omron inverters have been successfully implemented in this precision positioning application

Traditionally, a start/stop command system was used to move the load. However, because of the roughness of the electromechanical brake used to stop the crane, this method involved a serious lack of precision, mainly in vertical movement and in the positioning of the turbines on the bed.

The first stage of the newly developed system controls the crane's speed. Omron Sysdrive inverters (3G3XV and 3G3EV) have been installed on the horizontal and transverse axes (the length and breadth of the bay), making it possible to reduce crane speed gradually, to prevent sudden stops and consequent load swing. Furthermore, speed on the vertical axis, which requires even greater precision is controlled by a Sysdrive 3G3FV inverter, capable of providing 150% nominal torque from a frequency of 0Hz.

The entire operation of the crane is controlled from a central pushbutton station, enabling the operator to track load movement at all times. This system has not only achieved the accuracy Base staff hoped for, but has also enhanced safety and user friendliness.
