NGC Marine is a highly recognized international large adjustable paddle propulsion system supplier for the past six years has produced more than 700 sets of adjustable paddle, and a large number of exports to overseas markets, and its quality to meet international standards, to win customers and partners. Can be based on different types of ships and the requirements of the shafting arrangement of the machine - paddle - boat matching to optimize the design, in order to achieve high efficiency of the propulsion system, low-power requirements of environmental protection.
The Company may from 1120mm to 6700mm the various specifications tone of pitch propeller blade diameter, the maximum transmission power can reach 17000kW. Tone pitch propeller system is packaged capability and have the design and production of controllable pitch propeller propulsion system, such as stand-alone single-propeller shafting arrangement, the dual sculls and double machine and car. In addition, the tone pitch propeller system has a wealth of PTO configuration, can drive one or more of the load (shaft generator or fire pump) meet the needs of different types of ships and the function of supporting.
Performance characteristics detailed parameters of the hydraulic system control system applications
Is adapted to the harsh marine environment, the developers of NGC hydrodynamic calculation, structural design, material selection, give full consideration to the the adjustable paddle reliability requirements, the NCP series of controllable pitch propeller has good reliability, simple structure and ease of operation and maintenance, and other characteristics. The hub uses the large-diameter structure of the servo piston, the piston formed on the diameter of the fluid pressure acting on the guide rack, thereby reducing the hydraulic system required to provide the working oil pressure.
Highly skewed propeller propeller design process and optimize disk ratio measures, combined with experiments, effectively reducing the vacuoles and vibration of the propeller, not only to meet the speed, the drag force performance, but also to improve the use of the whole ship performance and economy.
The shafting design fully consider the changes with the load of the ship, the propeller the force, the gear load force produce and host crankshaft bending stress and other unfavorable factors in the the shafting strength, vibration and school, so that the calculated results with the actual conditions closer to or consistent.
Ship is sailing adjustable paddle if not at work, the blades can be adjusted to sailing status, effectively lowering its resistance.

NCP Series adjustable paddle hydraulic system with oil and hydraulic pump station. Hydraulic pump station has two types of single-pump and dual pump hydraulic pump station. Single pump hydraulic pump station to use as a spare pump, pump-driven machine with the main pump for the gearbox. There are two sets of two-pump hydraulic pump station electric pump, the standby switch automatically
The two structures with oil TYPE installed on the front of the gearbox or shafting, reliable, flexible features through a lot of the real ship inspection, both with oil.
The control valve European proportional valve
Pump import variable pump
valve block design simple, easy installation and maintenance, pipeline
The ODG-type with oil
ODG with oil installation in the output shaft of the gearbox, small size, reliable and easy installation and maintenance.
ODS with oil
The ODS with oil installed in the propulsion shafting, commonly used in low-speed diesel propulsion system and the long axis of the Department of Systems.
