KAMOME CPP have developed in 1961 by our original techniques. Since then, for over 40 years, as we listened to our customers needs and we continued improving and developing the products, and installed for all varieties of ships from small to large-sized twenty thousands hp (about sixteen thousands kW) ships. This has made it possible for us to supply over 4,600 sets of CPP. CPC-B type series are mainly applied for medium and large ships and propeller hub is solid type. Propeller blade is assembled one each base. In addition, assembled with reduction gear such as (CPR-BVH type , CR type ) are available.

Structure

Propeller group is consisted with Propeller blades, Solid type hub and Crank mechanism which is assembled into the inside of hub, and Propeller blades are fitted to guide block by bolts. Pitch control is made by rotating crank pin by guide blocks which are connected to Push-pull rod. Lubricating oil is filled to the inside of hub (Grease is sealed into hub of medium type), and O-rings are fitted to each sliding part and joined part. Replaceable sliding plates are inserted to sliding surface of propeller blades and hub where the most big pressure are given.

Oil distribution box is divided into two parts and supported by plane metal on the circular surface of Oil supply shaft and it does not rotate. At the inside, metal seal rings divided into two parts are fitted and supply high pressure hydraulic oil to the inside of rotating Oil supply shaft for the movement of piston. For checking of Oil distribution box, overhauling of Oil supply shaft is not necessary, and the replacement of parts is not necessary as no abrasive parts are existed.

3

For giving pressure to hydraulic oil stated in the above, standard Hydraulic unit is arranged. Standard unit is consisted with main pumpStand-by pumpElectric motorSolenoid controlled valveCooleretc. Hydraulic oil tank is to be arranged at ships bottom. Hydraulic circuit is consisted with circuits for hydraulic oil, lubricating oil plus cooling and high pressure hydraulic oil is circulated at the time of controlling propeller pitch only. During underway with steady pitch, lubricating oil only is circulated as the desired pitch is kept by Pilot check valve mechanism which is assembled to the inside of cylinder.

4

For pitch control system, in addition to standard type Electric remote control system various control functions such as ALC, OLP, PGM, ASC and combination control with main engine can be arranged by option. In addition, Joystick control (MACSMK) can be arranged for combination with Thruster and High performance rudder.

5

Cylinder group is located between propeller shaft coupling and oil supply shaft, and piston is directly connected to Push-pull rod as a part of shafting component. The movement of piston is transmitted to Push-pull rod and proceed pitch control of propeller blades. At the same time, pitch angle is transmitted from pitch detecting shaft which is fitted at bow side of piston to Follow-up transmitter. This pitch detecting mechanism is also acting as fixing the pitch of propeller blades at inboard adjustment as emergency pitch fixing tool.
