Hengxingda delivered the first set of ship side thrust capping device

On June 14, Nanjing Hengxingda Electromechanical Equipment Co., Ltd. independently developed China's first set of ship side thrust reduction and noise reduction and capping devices for shipment and delivery to a shipyard in Anhui.

The device is used for a ship equipped with a side thrust device, which is composed of four major systems: mechanical structure, hydraulic control, electrical control and monitoring alarm. The main body is a circular double-gate structure, the door leaf is semi-circular, and the device gate is divided into For the left and right, the opening direction is outward facing. The gate and the connecting cylinder of the device are installed at the inlet and outlet of the side push channel of the ship, the hydraulic control system and the mechanical transmission component are arranged in the engine room, the electrical control system is arranged in the electro-hydraulic control center of the device; the bridge is provided with device control The panel can be electrically controlled or controlled by an accumulator or manually. The device has a design life of more than 20 years and can withstand seawater immersion and marine life without damage. The entire capping device does not affect the normal operation of the ship's thrusting device when it is opened. It can basically maintain the original linearity of the hull when it is closed, and ensure that the ship is not affected when sailing at full speed. For ships equipped with thrusters, if the side thrust reduction and noise reduction and capping device is not installed, the original hull linearity is easily affected, and during the voyage, the hull linearity is incomplete and additional The resistance and air bubbles affect the speed and also interfere with the operation of the sonar equipment.

It is reported that Nanjing Hengxingda Electromechanical Equipment Co., Ltd. began research on drag reduction and noise reduction devices three years ago, and filed seven invention patents with the National Patent Office last year. At present, these seven patents are in the stage of acceptance of inventions.
