How to choose the type of marine winch
When choosing the type of marine winch, we need to know the specific functions of different types of equipment and the specific usage methods. These are especially important for all of us. When you can better understand the situation, know some corresponding usage methods, determine the relevant usage places, and some functions in the process of use, these aspects are understood before making a choice. There are many types of marine winches, and the main ones are manual and electric. Among the two types, they basically have their own characteristics. Correctly do a good job in understanding the corresponding and pay attention to the specific use methods before they can have good results. You can realize these aspects in the process of selection. Carefully understand the situation of these models, and be able to know some related matters, and then make a good choice, then the whole result will be better in the future.

Introduction and characteristics of marine hydraulic windlass
According to the anchor chain diameter, the anchor machine can be divided into 12mm-120mm and other models. The windlass can be divided into one side and two sides in China according to the wire rope. The key of the hoisting machine is composed of the base, support frame, sprocket, brake pedal, sprocket chain, transmission device, electronic control system (except manual hoisting machine), etc. The electric hoist has a motor, and the hydraulic hoist has a hydraulic oil pump and a hydraulic motor. Introduction and characteristics of marine hydraulic windlass The key technical performance analysis indicators of the windlass mainly include the diameter of the anchor chain, the rate of change of the nominal pressure of the anchor, the rated load, the application of different loads, the number of levels of speed control, electrical system, etc. The windlass installed on the ship shall ensure that the winding edge of the anchor chain and sprocket chain is 117-120 degrees. Characteristics of marine hydraulic windlass Marine hydraulic windlass is driven by high-pressure oil motor, and then the transmission gear of the transmission system is pushed by the reducer (no reducer is set), so that the windlass runs smoothly and the power device is stable in work, which is conducive to maintenance. The foundation of large-ton ships is hydraulic.

Design principle of hydraulic steering gear
Hydraulic steering gear is the core equipment of ship navigation, known as "sea navigation depends on the helmsman", hydraulic steering gear hydraulic steering smooth, fast, rudder position maintenance and steering switching smooth, is the priority of large and medium-sized ships to determine the equipment. Therefore, we introduce some points of attention in the selection of hydraulic steering gear. Nominal maximum torque: 10-500kN · m Steering time: ≤ 20s/65 ° (from one side 35 ° to the other side 30 °, single pump) Angle of rudder turning mechanism: ± 35 ° (limit theoretical angle: ± 36.5 °) tiller radius: 200-350mm Number of rudders: double rudders Rudder pushing device form: fork type Working pressure 8.5Mpa Safety valve adjustment pressure: 10.6Mpa Control form: electric control Oil pump unit: two sets of oil pump units, each for standby. Hydraulic oil grade and recommended for N32 thickened low-set hydraulic oil. Every ship shall be provided with such a main steering gear and a major auxiliary steering gear. The arrangement of the main and auxiliary steering gears shall be such that when one fails, the other does not fail. The main contents of the research on the structure information system of hydraulic steering gear include pump group, push rudder device and steering device, human emergency management system and fuel tank, etc. The steering wheel of the hydraulic steering gear is composed of three parts: steering mechanism, hydraulic system and steering control system. The function of the rudder pushing mechanism is to convert hydraulic energy into mechanical energy to push the rudder blade to deflect. The function of the hydraulic system is to provide sufficient hydraulic energy for the steering gear. The development of the main steering system device has its own sufficient strength problem and can carry out automatic steering when the operating capacity is advanced, so that the rudder can be transferred from 35 ° on either side to 35 ° on the other side, and the working time required for transferring from 35 ° on one side to 30 ° on the other side under the influence of the same environmental conditions shall not exceed 28s. The steering speed of the auxiliary steering gear can reach half of the forward speed of the operation, but not less than 7 kN, and the time required to turn the rudder from 15 degrees on one side to 15 degrees on the other side does not exceed 60 seconds. There are two functions of the steering control management system: one is to transmit information to the steering order, and the other is to control the steering accuracy.
