In the heavy machinery industry, ensuring the reliability of hydraulic components after maintenance is crucial. Whether it’s a pump, motor, valve, or cylinder, verifying performance before re-installation saves time and money. Today, we are introducing the HP-A55KW Hydraulic Pump Valve Cylinder Comprehensive Test Platform by Beacon Machine, a robust solution designed to meet the rigorous standards of GB3766-88.
The HP-A55KW is a high-power, integrated test bench designed for the factory inspection and testing of hydraulic pumps, motors, valves, and oil cylinders. It utilizes a 55KW electric motor as the primary driving system and features a comprehensive layout divided into three main sections:
Motor Drive Table: Where the pump/motor is mounted and driven.
Main Oil Box Valve Console: The control center for pressure and flow regulation.
Valve and Tank Detection Table: Dedicated area for component testing.
Dust-Proof Design: The system adopts a closed oil tank structure, allowing it to operate effectively even in dusty industrial environments.
Integrated Oil Circuit: The oil circuit block design minimizes leakage points, making the structure compact and easy to disassemble for maintenance.
User-Friendly Interface: Equipped with both digital meters and a PLC touch screen display, the machine offers a clear and simple interface for monitoring pressure and flow.
Neat Layout: The output oil circuits are arranged neatly to facilitate easy operation and pipe connection.

Before selecting a test bench, understanding the specifications is key. The HP-A55KW delivers impressive power:
Main Driver Power: 55KW (Level 4 Motor)
Auxiliary Motor: 5.5KW (Low-voltage oil supply)
Speed Range: 0--2000 r/min (Frequency conversion control)
Max System Pressure: 30 MPa (Limit pressure) / Supply pressure up to 20 MPa
Max Flow: 300-400 L/min
Oil Tank Volume: 1000L (Actual refueling capacity approx. 800L)
Dimensions: 2000 x 2000 x 1800 mm
Oil Cleanliness Requirement: ISO VG46 Hydraulic Oil (NAS10 Level)

The HP-A55KW is versatile. Here is a breakdown of the testing procedures it supports:
The machine can handle both self-priming (open) and forced oil supply (closed) systems.
Preparation: Ensure the impact switch is set correctly and the rotation direction matches the pump.
Procedure:
Start the low-voltage oil supply motor and adjust pressure to 1.5–2 MPa.
Start the main motor and adjust speed between 800–1800 rpm.
Monitor the flow meter and pressure gauges.
Apply load using the loading pressure control knob while maintaining constant speed.
Setup: Connect the valve to the high-voltage ports (A, B, C, D) on the pumping countertop.
Process: Open the relevant ball valves and operate the manual rods to test control methods and detection values.
Procedure:
Start the main motor and adjust to operational speed.
Adjust the loading pressure control knob (Left side).
Hold the pressure for 1 minute to check for fluctuations in the pressure gauge, ensuring the cylinder seal integrity.

To ensure the longevity of your HP-A55KW, follow these essential guidelines:
Installation:
Leveling: The machine must be firmly fixed to the foundation according to design drawings to prevent vibration.
Sealing: Ensure all pipe connections are sealed correctly to prevent leakage.
Filtration: When filling the tank for the first time, use a filter vehicle with an accuracy of at least 20um.
Maintenance:
Oil Change: Replace hydraulic oil every other year. Always clean the oil tank and replace the filter element during an oil change.
Filter Checks: If the oil absorption or return filters become blocked, clean or replace them immediately to prevent pump damage.
Cleanliness: Keep tested pumps and motors internally clean to avoid contaminating the test bench system.
The HP-A55KW Comprehensive Test Platform is an essential asset for any hydraulic repair shop or manufacturing facility. Its combination of high power, precise digital control, and versatile testing capabilities ensures that your hydraulic components are road-ready and reliable.
