BM Hydraulic Motor
The BM hydraulic motor is an axial porting hydraulic motor. Its housing is cast from ductile iron with sufficient strength, making it suitable for applications with low loads and intermittent operation. The main features of the motor are as follows:
- Adopts an axial oil distribution structure, featuring small size, high efficiency, and long service life.
- The shaft seal can withstand high pressure and allows series or parallel connection for use.
- Enables easy forward and reverse rotation with stable rotational speed.
- Compared with other hydraulic motors, it offers high cost-effectiveness.
Open-Loop Hydraulic System
In this type of system, the hydraulic pump draws oil from the oil tank, and the actuator discharges oil back to the oil tank. The system requires an oil tank with a relatively large capacity. This type of system is more widely used.
Closed-Loop Hydraulic System
In a closed-loop system, the hydraulic oil discharged by the actuator is returned to the inlet of the pump. The system has relatively high efficiency, but it requires a charge pump to replenish oil and a flushing valve to replace oil for heat exchange. Systems involving travel hydraulic motors are mostly used in mechanical equipment such as vehicles, lifting and conveying machinery, marine hoisting winches, and equipment in the papermaking and textile industries.
Hydraulic Transmission System
A hydraulic transmission system is generally an open-loop system without feedback. It mainly focuses on transmitting power, with signal transmission as a secondary function, and pursues the optimization of transmission performance. The working characteristics of the system are determined by the performance of the various hydraulic components that constitute it and their interactions, and its working quality is greatly affected by changes in working conditions. Hydraulic transmission systems are widely used; most mechanical hydraulic systems fall into this category.
