Scope of Use:

The Bidirectional Power Unit is utilized across various industries and applications, including:

Industrial Machinery: Used in manufacturing facilities for equipment operation and control.

Construction: Employed in construction machinery for tasks such as lifting, pushing, and pulling heavy loads.

Automotive: Integrated into hydraulic systems for vehicle lifts, brakes, and steering.

Agriculture: Utilized in agricultural machinery for functions like tilting, lifting, and positioning.

Marine: Installed in marine equipment for hydraulic control of winches, cranes, and steering systems.

Material Handling: Applied in conveyor systems, loading docks, and hydraulic presses for material transport and processing.

Typical Scenarios:

Lifting Operations: Used to raise heavy loads vertically, such as in vehicle repair lifts or material handling equipment.

Pushing and Pulling: Employed in construction machinery for pushing or pulling heavy objects, such as in bulldozers or excavators.

Tilting and Positioning: Utilized in agricultural machinery to adjust the angle or position of implements, such as plows or harvesting equipment.

Braking and Steering: Integrated into automotive systems to provide hydraulic pressure for braking and steering control.

Material Processing: Applied in hydraulic presses for forming, stamping, or molding materials in manufacturing processes.

Winch and Crane Control: Used in marine and industrial settings to operate winches, cranes, and hoists for lifting and lowering operations.

Operating Methods:

The Bidirectional Power Unit operates through a hydraulic system, typically consisting of:

Hydraulic Pump: Generates hydraulic pressure by converting mechanical power into fluid flow.

Hydraulic Cylinder: Converts hydraulic pressure into linear mechanical force for performing work.

Control Valves: Regulate the flow and direction of hydraulic fluid to control the movement of hydraulic actuators.

Reservoir: Stores hydraulic fluid and ensures proper lubrication and cooling of hydraulic components.

Power Source: Can be electric, diesel, or gasoline-powered, providing the energy to drive the hydraulic system.

Product Parameters:

Power Output: Typically measured in horsepower (HP) or kilowatts (kW), indicating the amount of mechanical power generated by the unit.

Pressure Rating: Specifies the maximum hydraulic pressure the unit can deliver, measured in pounds per square inch (psi) or bar.

Flow Rate: Indicates the volume of hydraulic fluid circulated by the unit per unit of time, measured in gallons per minute (GPM) or liters per minute (LPM).

Cylinder Force: Reflects the maximum force exerted by the hydraulic cylinder, typically measured in pounds (lbs) or Newtons (N).

Reservoir Capacity: Denotes the volume of hydraulic fluid the reservoir can hold, measured in gallons or liters.

Additional Information:

Safety Features: The Bidirectional Power Unit may include safety features such as pressure relief valves, emergency stop mechanisms, and overpressure protection to ensure safe operation.

Maintenance Requirements: Regular maintenance, including fluid checks, filter replacement, and component inspections, is essential to ensure optimal performance and longevity of the power unit.

Environmental Considerations: Proper disposal of hydraulic fluid and adherence to environmental regulations are necessary to minimize environmental impact.

In summary, the Bidirectional Power Unit is a versatile hydraulic product widely used in various industries for a range of applications, offering reliable hydraulic power, precise control, and efficient operation. Its robust design, along with safety features and maintenance requirements, makes it an essential component in many hydraulic systems.

This hydraulic power unit is composed of bidirectional gear pump,DC motor, multi- purpose integrated block,hydraulic valve, tank and other parts.It can change the oil direction without reversing valve.With small size,compact structure,stable performance, it is widely used in vehicle machine tools and other equipment.

Special Notes

1. For different flow rate pump, pressure and motor power, please check the ordering guidance.
2. This motor is based on gap working system S2=2 ~ 4min(continuous working time), so it cannot run continuously.
3. Before installation, the cylinder, oil pipe, joint and other hydraulic components must be cleaned and free from any impurities.
4. The viscosity of hydraulic oil should be 15- 68cst and should be clean and free of impurities.HM46 hydraulic oil is recommended.
5. Check that whether there is enough oil in the oil tank immediately after the first operating of the system.
6. The hydraulic oil should be replaced after the first 100 hours' use of the system, and change the oil every 3,000 hours after that.
