Steady Performance At Low Speed Hydraulic Drive Motor For Shipping Industry
This hydraulic motor uses a crankshaft linkage structure and is a single-acting radial piston hydraulic motor.
Due to its simple structure and reliable operation, it is a low-speed high-torque hydraulic motor that is currently used more.
Especially applied in mining machinery and plastic machinery.
Main Characteristics:
- Low noise
| Low noise due to its crankshaft & con-rod structure and cylinder & piston framework of low vibration frequency. |
- Steady performance
| Steady performance at low speed; high starting torque. |
- High mechanical efficiency
| The bearing support structure is adopted between the crankshaft and the connecting rod, and the mechanical efficiency is high. |
- Good reliability and less leakage
| Good reliability and less leakage due to the flat compesation distributor; special seals between piston and cylinder guarantee its higher volumetric efficiency. |
- Reversible rotation
| Enable reversible rotation and certain external radial & axial force on output shaft. |
Application:
Hydraulic transmission of mining, construction, engineering machinery, lifting and transportation equipment, metallurgy, petroleum and coal mines, marine machinery, plastic machinery, geological drilling and other machinery.
NIM series crankshaft and connecting rod type low speed high torque hydraulic motors are manufactured according to the technology and standards from Italy. Base on this, we also continue to carry out technical improvements to get excellent performance of products according to the market needs.
Advantage:
1. Good reliability
2. high efficiency
3. long life
4. ow noise
5. wide speed range
