TCVVP-F3030-A4-1 Variable Vane Pump | Toyooka Replacement | Injection Molding Machine Pump

The TCVVP Series (specifically the TCVVP-F3030-A4-1) by Chengyuan Hydraulic is a high-performance, double-variable displacement vane pump. Designed primarily for injection molding machines and shoe-making machinery, this series features an integrated pressure compensation mechanism that adjusts flow automatically based on load requirements, significantly reducing energy consumption. We emphasize 100% original-place interchangeability with Toyooka standards. At Chengyuan, every pump undergoes 100% simulated condition testing to ensure exceptional pressure stability and long-term reliability, providing the precision power needed for high-quality molding processes.

Technical Specifications (Bulleted List)

Key Technical Advantages

• High Energy Efficiency: By adjusting the stator eccentricity, the TCVVP pump reduces flow to near-zero once the preset pressure is reached. This minimizes overflow losses and heat generation, leading to substantial electricity savings.

• Dual-Pump Independent Control: The F3030 design allows two separate variable pumps to share one drive shaft. Each pump can be independently tuned to meet different pressure demands for molding and injection stages.

• High-Sensitivity Compensator: The built-in high-precision pressure compensator features a fast response time, allowing the system to adapt instantly to load fluctuations, reducing hydraulic shock and improving product accuracy.

• Silent Operation Design: Optimized stator curves and vane slot geometry, combined with heavy-duty bearings, ensure the pump operates quietly (typically below $65\text{ dB(A)}$), improving the workshop environment.

Application Areas

• Injection Molding Machines: Powering mold clamping, ejection, and injection cycles.

• Shoe-Making Equipment: Ideal for rotary injection machines and outsole molding units.

• Machine Tools: Auxiliary hydraulic circuits requiring pressure-holding and variable flow control.

Expert Maintenance Tips

• Pressure Setting: When adjusting the A4 compensator, rotate the adjustment bolt slowly under no-load conditions. Ensure the setting does not exceed the $7\text{ MPa}$ rated limit.

• Oil Cleanliness: Variable pumps are sensitive to contamination. Maintain oil at ISO 4406 19/17/14 standards and use $10\text{ }\mu\text{m}$ filtration.

• Case Drain Management: An independent case drain line must be connected directly to the reservoir. Ensure the drain back-pressure is below $0.03\text{ MPa}$ to maintain the sensitivity of the variable mechanism.
