As the name suggests, the frequency conversion winch for crane ships is a frequency conversion winch for crane ships. First of all, know the crane ship, also known as the floating crane. Used for water lifting and hoisting operations, generally non-self-propelled, but also self-propelled. A crane is installed on the crane. Crane ships with frequent operations are usually self-propelled, and their cranes can rotate. When lifting extremely large items, two crane ships can be combined. The frequency conversion winch is an electric drive, which is used for lifting and hoisting goods by a crane.
Overview of the characteristics of frequency conversion winches for cranes
1. Good explosion-proof performance;
2. Stable stepless speed regulation performance and low-speed running performance;
3. Obvious energy saving effect:
Due to the hydraulic closed-circuit transmission, the system is always in the power-generating braking state under the lowering conditions, so that the gravitational potential energy is converted into electrical energy to feed back to the grid, which not only reduces the heating of the hydraulic system, but also saves electrical energy, and the energy-saving effect is obvious.
Compared with the low-speed hydraulic motor hydraulic winch, the hydraulic winch driven by the high-speed hydraulic motor is driven by the whole machine, which has good energy-saving effect.
4. Flexible changes in technical parameters, reasonable matching, and large room for selection:
The speed ratio parameters of the reducer can be reasonably selected according to the size of the load and speed, so that the parameters of the hydraulic pump and the hydraulic motor can be matched. The variable pump-variable motor speed control method is adopted (not for low-speed hydraulic motors), which can achieve light load, high speed and heavy load. Load low-speed operating conditions to give full play to equipment capabilities. Compared with the low-speed hydraulic motor solution, the pulling force or speed can be increased under the same power condition; while under the same pulling force and speed condition, the installed power can be reduced and electric energy can be saved.
5. Compact structure and small size, which can save the infrastructure cost of the chamber:
Because the planetary gear reducer is directly connected to the main shaft, and the high-speed hydraulic motor is directly connected to the planetary gear reducer, the main engine has a short axial size and a compact hydraulic system, so it has a compact structure and a small volume, which can save the infrastructure cost of the chamber. .
6. The equipment has a long service life, the standard spare parts are easy to purchase and the price is low, the maintenance workload is small, and the comprehensive operating cost is low.
Compared with the low-speed hydraulic motor solution, the high-speed hydraulic motor is a standard hydraulic component with stable performance, long life, easy purchase, low price, and reduced maintenance workload. Although the one-time investment is relatively high, the overall operating cost is low.
7. The operation is sensitive, simple and convenient:
All the operations of the winch can be completed with only one handle, and the operation is sensitive, accurate, simple and reliable.
