This is achieved through the precise, positive displacement of gear sections.* Flow Division and Combination: It can divide a single inlet flow into multiple precisely proportioned outlet flows, or combine multiple return flows into a single outlet. This dual capability is essential for synchronizing actuators in both directions of movement.* High Efficiency and Low Dissipation: Unlike some other types of flow dividers, gear-type dividers are non-dissipative. They do not waste energy as heat; instead, energy is transferred via the common shaft, contributing to system efficiency.* Tolerance to Contamination: Gear flow dividers generally exhibit better tolerance to contamination compared to spool-type dividers, making them more robust in demanding industrial environments.* Pressure Intensification: In certain configurations, these units can act as pressure intensifiers, boosting pressure in a specific circuit when needed.* Modular Design: The PLD20 series features a modular design, allowing for various configurations with different numbers of sections and displacements to meet specific application requirements.* Durability: Constructed from high-strength materials like aluminum alloy or cast iron, these units are built for longevity and reliable performance in harsh conditions.Application Scenarios:The CASAPPA PLD20 gear flow divider synchronizer finds application in a wide array of industrial and mobile hydraulic systems where synchronized movement is critical. These include:* Lifting Platforms and Scissor Lifts: Ensuring level and stable lifting by synchronizing multiple hydraulic cylinders.* Heavy Machinery: Synchronizing cylinders or motors in excavators, loaders, agricultural equipment (e.g., seeders, balers), and construction machinery for precise and controlled operations.* Presses and Clamping Systems: Providing synchronized force and movement for stamping, bending, and clamping operations.* Conveyor Systems: Ensuring consistent movement of multiple belt sections or actuators.* Robotics and Automation: For precise coordinated movements of robotic arms or automated guided vehicles.* Material Handling Equipment: Synchronizing lift gates, container handlers, and forklifts.* Vehicle Applications: In specialized vehicles like concrete mixers, garbage trucks, and specialized transport systems.Usage Instructions:1. Mounting: Ensure the flow divider is mounted securely to a stable surface, aligning it with the hydraulic pump and actuators. Proper alignment is crucial for efficient operation and longevity.2. Plumbing: Connect the inlet port(s) to the hydraulic pump's output. Connect the outlet ports to the respective hydraulic cylinders or motors. Ensure all connections are clean and properly sealed to prevent leaks.3. Fluid Selection: Use hydraulic fluid compatible with the seals and operating temperatures. Mineral oil based fluids are common, but fire-resistant fluids may also be used if specified. Consult the manufacturer's recommendations for optimal fluid viscosity and type.4. System Priming: Before initial startup, prime the system to remove all air. Air in the hydraulic system can lead to inefficient operation, inconsistent synchronization, and potential damage.5. Rotation Direction: Gear flow dividers have a specified direction of rotation. Ensure the pump is rotating in the correct direction to drive the flow divider as intended. This is typically indicated by an arrow on the unit or in the documentation.6. Relief Valve Settings: If the unit is equipped with relief valves (VPEF), ensure they are set to the appropriate pressure for the system. Over-pressurization can damage components.7. Load Balancing: While flow dividers excel at synchronization, significant load differences can still impact performance. Ensure loads are as balanced as practically possible.Precautions:* Contamination Control: Maintain a high level of cleanliness in the hydraulic system. Contaminants can cause premature wear and affect the precision of the flow division.* Operating Range: Operate the flow divider within its specified speed, pressure, and temperature ranges to ensure optimal performance and lifespan.* Cavitation Prevention: Ensure adequate system flow and pressure to prevent cavitation, which can damage the gears.* Seal Compatibility: Verify that the seal material is compatible with the hydraulic fluid being used.* Overrunning Loads: In applications with significant overrunning loads, additional control measures like counterbalance valves might be necessary, especially with certain types of flow dividers.* Synchronization Limitations: While gear flow dividers offer high precision, they are not absolute positive-holding devices when stationary. Some minor drift may occur over time, especially if actuators are not allowed to reach the end of their stroke regularly.* Maintenance: Regularly inspect the system for leaks, fluid degradation, and excessive wear. Follow the manufacturer's recommended maintenance schedule.--- Frequently Asked Questions about CASAPPA PLD20 Gear Flow Divider SynchronizerQ1: What is the primary function of a gear flow divider like the CASAPPA PLD20?A gear flow divider's main purpose is to split a single hydraulic fluid flow from a pump into two or more precisely controlled, separate flow paths. This precise division is critical for synchronizing the movement of multiple hydraulic actuators, such as cylinders or motors, ensuring they operate in unison. It achieves this through the positive displacement action of meshing gears, where each gear section moves a fixed volume of fluid per revolution, thereby maintaining a consistent flow ratio between outlets regardless of load variations.Q2: How does the CASAPPA PLD20 ensure synchronization between hydraulic cylinders?The CASAPPA PLD20 synchronizes hydraulic cylinders by dividing the incoming flow from the pump into equal or proportional streams for each connected cylinder. Because the gear sections are mechanically linked, they rotate at the same speed, delivering a consistent flow rate to each cylinder. This equal flow distribution ensures that all cylinders extend and retract at the same rate, maintaining their relative positions and preventing uneven movement, even if the cylinders experience different external loads.Q3: Can the CASAPPA PLD20 handle applications with unequal loads on the cylinders?Yes, gear flow dividers like the CASAPPA PLD20 are designed to handle applications with unequal loads. While external loads can affect the pressure within each cylinder's circuit, the flow divider's internal gearing ensures that the flow rate to each cylinder remains consistent. This means that even if one cylinder is more heavily loaded, it will still receive the same amount of fluid flow as the less-loaded cylinders, allowing them to move in sync. Integrated relief valves can help manage pressure differentials, and some models can act as flow equalizers to ensure cylinders can catch up if one lags.Q4: What are the main advantages of using a gear-type flow divider over other synchronization methods?Gear-type flow dividers offer several advantages, including high precision and efficiency due to their positive displacement nature, which minimizes energy dissipation as heat. They are also generally more tolerant to hydraulic fluid contamination compared to spool-type dividers. Furthermore, their ability to divide and combine flow makes them effective for synchronizing actuators in both extension and retraction cycles, and they can be configured with multiple sections for complex systems.Q5: What are the typical applications for a CASAPPA PLD20 Gear Flow Divider Synchronizer?Typical applications include synchronizing hydraulic cylinders in lifting platforms, scissor lifts, agricultural machinery (like balers and seeders), construction equipment, material handling systems, presses, and clamping devices. They are also used in mobile hydraulics for applications such as truck mixers, cranes, and specialized industrial machinery where multiple actuators must operate in perfect coordination.Q6: How does the CASAPPA PLD20 differ from a flow equalizer?While both are types of gear flow dividers, a flow divider can distribute flow into unequal parts for different actuators, whereas a flow equalizer is specifically designed to divide flow equally among identical actuators to ensure they move in perfect synchronization. The PLD20 series can function as either, depending on the configuration of gear section displacements. When sections have identical displacements, it acts as an equalizer; when displacements are different, it acts as a divider.Q7: Can the CASAPPA PLD20 be used to synchronize hydraulic motors as well as cylinders?Absolutely. The principle of precise flow division applies equally to hydraulic motors. The CASAPPA PLD20 can be used to ensure that multiple hydraulic motors operate at the same speed, which is crucial in applications like multi-motor conveyor systems, car wash systems, or hydraulic drive systems where uniform speed is required.Q8: What is the role of integrated relief valves (VPEF) in the CASAPPA PLD20?Integrated relief valves, often designated by "VPEF," provide over-pressure protection for individual sections of the flow divider. They help prevent damage if a cylinder or motor stalls or encounters an obstruction. More importantly for synchronization, these valves can allow a "lagging" cylinder to catch up by diverting excess fluid back to the inlet or tank, effectively re-synchronizing the system at the end of a stroke.Q9: What are the limitations of gear flow dividers in synchronization applications?While highly effective, gear flow dividers have limitations. They are not positive-holding devices when stationary, meaning minor drift can occur over time due to internal leakage, especially if actuators don't reach their full stroke periodically. Synchronization accuracy can also be affected by significant pressure differentials between sections or if the system operates outside the recommended speed and temperature ranges. Additionally, efficiency can decrease at very low speeds or extreme pressures.Q10: How is the flow rate for each section of the CASAPPA PLD20 determined?The flow rate for each section is primarily determined by its displacement (cm3/rev) and the rotational speed of the flow divider. The total flow from the pump is divided proportionally to the displacement of each gear section. Manufacturers provide selection guides and graphs that help determine the appropriate displacement for each section based on the required flow rate and operating speed for the specific application. For the PLD20/4/CS-GE/11,2-GD/ configuration, each of the four sections has a displacement of 11.2 cm3/rev.Beijing Zhongping Technology Co., Ltd. is a leading provider of industrial automation solutions, intelligent robotics, and advanced system integration services.
