Concrete Pump Deck Pipe Introduction To The Classification

May 27, 2017

  Concrete Pump Deck Pipe Deck machinery is the ship deck machinery, is installed on the ship deck of the machinery and equipment, is an important part of the ship. Deck machinery is to ensure that the ship is normally sailing and the ship docked dock, loading and unloading cargo, the upper and lower passengers need the mechanical equipment and equipment. Ship deck machinery can be divided into large deck machinery and small deck machinery. Mainly include steering gear, windlass and winch, cable guide, with cable pile (supporting the piles), cable roller and so on.

Ship deck machinery can be divided into large deck machinery and small deck machinery.

Ship deck machinery can be divided into large deck machinery and small deck machinery.

Large deck machinery mainly include: steering gear, windlass and winch, hydraulic hatch cover, bow thruster, Small deck machinery mainly includes cable guide, with cable pile (the Department of embrace the pile), cable roller and so on.

  Concrete Pump Deck Pipe The size of the steering gear from the outfitting in accordance with the norms of classification societies decided to select the main consideration when the torque (kN / m), in the design work there are two assessment points:

1. Host in the MCR (maximum sustained and stable conditions) state, the rudder angle from 35 ° to the other side of the 30o need to be completed within 28sec.

2. The calculation of the rudder stock, ie its diameter.

The steering gear (about 125kg) is currently electrohydraulic, that is, hydraulic equipment by the electric equipment for remote control operation. Product form divided into two categories:

1. Reciprocating plunger (74000DWT bulk carrier), the principle is through the conversion of high and low pressure oil and work to produce a linear motion, and through the tiller into a rotary motion.

2. Rotary steering gear (chemical ship), the principle is the role of high and low pressure oil directly on the rotor, small size and efficient, but the cost is higher.

Concrete Pump Deck Pipe Manufacturers: reciprocating plunger steering gear (domestic production) abroad mainly by Japan Kawasaki, Germany HATLAPA provided by the domestic by Taixing Ke Pan Pan Ship Equipment Co., Ltd.. Rotary-type steering gear (full import) is mainly produced by Rolls-Royce small, Frydenbo production of large.

Differences between two types of steering gears:

Reciprocating plunger steering gear above the rudder bearing the weight of the rudder system, the next rudder bearing to locate, the tiller into the amount of only a few millimeters; and the rotor-type steering gear does not need on the rudder, directly by the steering gear load, but in the The steering gear platform needs to be considered watertight, and the tiller should be tens of millimeters. Reciprocating plunger steering gear on the size of the larger requirements. Reciprocal plunger can be deflected to less than 40o to a side, turning the steering gear up to 70 o.

The role of the hydraulic system is high and low voltage conversion, the pressure loss into mechanical movement. Including 1. High pressure pump (with pressure oil) 2. Control, operating equipment 3. Actuator (oil motor, cylinder plunger, etc.).
