90kW Hydraulic Valve Testing Machine with 380L/Min Flow Rate and 0-30MPa Pressure Range for Gear Pump Performance Evaluation
The 90kW Pump Truck Hydraulic Valve Testing Machine is a professional-grade testing system designed for comprehensive performance evaluation of hydraulic gear pumps and valves. With a maximum flow rate of 380L/min, this industrial testing equipment ensures precise measurement and validation of hydraulic components under various operating conditions.
This hydraulic test bench performs factory cleaning and efficiency testing for hydraulic gear pumps. The system conducts impact loading tests at different speeds and pressures while measuring and recording critical parameters including output flow, input torque, and performance characteristics at specified operating conditions.
- PLC automatic control system for precise operation
- Proportional valve loading for hydraulic pump testing
- Computer-aided test system with data analysis capabilities
- Automated test report generation upon completion
- Supports automatic testing of gear pumps with displacement less than 20mL/r
- Test Bench: Primary station for gear pump sweeping, efficiency testing, and data acquisition
- Pre-Assembly Station: Supports testing operations with transition stop plates, oil port tooling, connection splines, and pre-installation of test piece oil ports
- Cleaning & Draining Station: Automatically flushes and drains tested pumps at low speed to remove metal particles and residual hydraulic oil
This hydraulic valve testing machine is suitable for performance testing of hydraulic components across multiple industries including engineering machinery, metallurgical equipment, petroleum machinery, aerospace systems, shipbuilding applications, and general industrial machinery.
