80 Db Hydraulic Piston Pumps Variable Displacement Coal Mining
B1-300 Five-Star Motor Hydrualic Motor Five Star Hydraulic Motor For Petroleum And Coal Mining, Plastic Machinery
Product Description:
Low-speed high-torque motor, no connecting rod structure, the driving part is an eccentric spherical pair, no lateral force;
Fully balanced and compensated oil distribution, high reliability;
The starting efficiency is as high as 90%, and the volumetric efficiency and mechanical efficiency are high;
The minimum speed is 0.5~1 revolutions per minute, and the minimum speed is stable.
Appliion areas:
Injection molding machines, hydraulic rotary lifting machinery, road machinery, snow removal vehicles and other fields.
Main Features:
1. Five-piston structure with eccentric shaft and low excitation frequency, has the characteristics of low noise;
2. Large starting torque, good stability at low speed;
3. Plane compensation oil distributor with good reliability and no leakage; piston and plunger sleeve are sealed by a sealing ring, which has high volumetric efficiency;
4. Roller supports are provided between crankshaft and connecting rod, has high mechanical efficiency;
5. Rotation direction is reversible, and output shaft is allowed to bear radial and axial external forces;
6. High power quality ratio, small volume and weight.
7. Noise is less than 80 dbs.
