The reason why hydraulic winch produces pulsation

The reason why hydraulic winch produces pulsation
Hydraulic winch as a novel commodity to further improve, widely used in Marine technology, engineering construction, water conservancy and hydropower engineering and other levels, we carry out the improvement of the winch, the rope will have a certain beat, this is because of what? Here is a brief introduction to the causes of jumping:
First, the reason for jumping:
1. When the winch is raised, the friction resistance of the operating load is large or small, it will lead to the rope jumping up and down.
2. The destruction of the wire rope drum guide rope, the rope is blocked, causing the coil skew to vibrate, which will lead to the rope jumping up and down.
3, improve the electrical control system touch is not very good or gear transmission part of the common failure caused by unstable operation, will also lead to wire rope jumping up and down.
Two, how to prevent beating
1, in order to prevent beating, we need to consider from the source, from the choice to prevent beating.
How does the hydraulic winch jump when it is raised
2, choose quality to ensure:
In order to choose the suitable random winch, in its selection also need to choose to ensure the quality of the winch, after all, only the quality of the machinery and equipment can be ensured in the specific use of customers satisfactory application of the actual effect.
3, look at the high cost performance:
Whether you want to choose the right random winch, or choose other suitable industrial equipment, in the whole process of selection can be carried out according to the cost-effective choice, generally cost-effective machinery and equipment it is more suitable at all levels.
In engineering construction, water conservancy and hydropower engineering, forestry and fruit industry, mining, port and other raw materials lift or flat tow we can use hydraulic winch, resulting in a lot of reasons for the winch to beat, we should be based on their own specific situation to distinguish.

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 speed, rudder position maintenance and steering smooth, is the priority equipment of large and medium-sized ships. So, we introduce some attention points of hydraulic steering gear selection.
Nominal maximum torque: 10-500kN·m
Steering time: ≤20s/65°(turn from 35° on one side to 30° on the other side, single pump)
Steering mechanism Angle: ±35° (limit theoretical Angle: ±36.5°)
Tiller radius: 200-350mm
Rudder number: Two rudders
Rudder pushing device form: fork type
Working pressure 8.5Mpa
Adjusting pressure of safety valve: 10.6Mpa
Control form: electric control
Oil pump set: Two sets of oil pump set, each as backup.
Hydraulic oil brand and recommended as N32 gelled low point hydraulic oil. Each ship shall be provided with such a main steering gear and an important auxiliary steering gear. The main steering gear and auxiliary steering gear should be arranged so that when one fails, the other will not fail.
The research of hydraulic steering gear structure information system mainly includes pump group, steering gear and steering gear, human emergency management system and oil tank.
The steering wheel of hydraulic steering gear is composed of steering mechanism, hydraulic system and steering control system. The role of the rudder pushing mechanism is to convert hydraulic energy into a mechanical energy that pushes the rudder blades to deflect. The function of the hydraulic system is to provide enough hydraulic energy for the steering gear. The main steering system device is developed with sufficient strength problems of its own and is capable of steering automatically at operational forward speed so that the rudder can be shifted from 35° on one side to 35° on the other and the operating time from 35° on one side to 30° on the other side is not more than 28s under the same environmental conditions. The steering speed of the auxiliary steering engine can reach half of the operating forward speed, but not less than 7,000 N. It takes less than 60 seconds to turn the rudder from 15 degrees on one side to 15 degrees on the other. The role of steering control management system has two kinds: one is information transmission steering order, the other is through control steering accuracy.
How to choose the type of Marine winch well
When choosing the type of Marine winch, we need to know the specific functions of different types of equipment, as well as the specific use methods, which are particularly important for all of us. When you can better understand the situation, know the corresponding use ways, determine the relevant use places, and some functions in the process of use, Know all of these things before you make a choice.
There are many types of Marine winch, and the main ones are manual and electric. Basically, these two types have their own characteristics. Only by correctly understanding and paying attention to specific methods of use can they have good results. Carefully understand these models and be able to know some of the relevant matters before making a good choice, then the overall outcome will be better in the future.
