Voltage Options: Forklift HPUs are available in both 220V and 380V configurations, catering to different power supply systems and voltage requirements in various regions.
The choice between these voltage options depends on factors like load capacity, duty cycle, and local electrical standards.
Power Output: Forklift HPUs are designed to deliver a specific power output, typically measured in horsepower (HP) or kilowatts (kW). The power output required depends on the forklift's capacity and intended application. Higher-powered HPUs are needed for heavier loads and more demanding tasks.
Flow Rate: Forklift HPUs control the flow of hydraulic fluid to the lift cylinders, tilt cylinders, and other hydraulic components. The flow rate is typically measured in liters per minute (LPM) or gallons per minute (GPM). A higher flow rate allows for faster lift and tilt movements.
Pressure Rating: The pressure rating of a forklift HPU is measured in pounds per square inch (PSI) or bar. It indicates the maximum hydraulic pressure the unit can generate to lift and maneuver heavy loads safely. The pressure rating should match the requirements of the hydraulic system and the load capacity of the forklift.
Tank Capacity: Forklift HPUs have hydraulic reservoirs (tanks) that store hydraulic fluid. The tank capacity affects the system's cooling capacity and the amount of hydraulic fluid available for continuous operation. Larger tanks can support longer working hours without overheating.
Duty Cycle: The duty cycle specifies how long the HPU can operate continuously before requiring a cooling or rest period.
Duty cycles are often expressed as a percentage, indicating the ratio of operating time to resting time. Understanding the duty cycle is crucial to prevent overheating and ensure the HPU's longevity.
Electric Motor: The electric motor, powered by the 220V or 380V electrical supply, converts electrical energy into mechanical energy to drive the hydraulic pump.
Hydraulic Pump: The hydraulic pump pressurizes the hydraulic fluid, which is then distributed to various hydraulic components, such as cylinders and valves.
Reservoir Tank: The tank stores hydraulic fluid, helps dissipate heat, and ensures a continuous supply of fluid to the system.
Valves: Valves control the flow and direction of hydraulic fluid, enabling precise control of the forklift's movements.
Filters and Coolers: These components maintain the cleanliness and temperature of the hydraulic fluid, preventing contamination and overheating.
Pressure Relief Valve: It protects the hydraulic system from overpressure, ensuring the safety of the forklift and its operators.
