Hydraulic Pump and Motor Test Bench

Hydraulic Pump and Motor Test Bench：

The hydraulic pump motor test bench equipment is suitable for factory inspection and testing of various hydraulic pumps (including hydraulic gear pumps, plunger pumps, vane pumps, closed pumps, internal gear pumps, etc.) and hydraulic motors in terms of liquid flow and pressure measurement, output torque and speed measurement, output power measurement, and temperature rise measurement. It can display the relationship curve between various parameters and time in real time, record the entire testing process, and output a report. It is commonly used for product factory testing and type testing.

Typical application scenarios：

1. Hydraulic component manufacturer (factory quality inspection/type testing)

Gear pumps, plunger pumps, hydraulic motors, etc. undergo 100% factory performance testing to ensure qualified delivery.

New product development finalization and type testing, verifying design, optimizing parameters, and obtaining certification data.

Batch production consistency sampling, monitoring process stability, and reducing defect rate.

2. Construction machinery/host factory (installation inspection/after-sales maintenance)

Hydraulic pumps/motors for excavators, loaders, cranes, tunneling machines, etc. are stored and tested before installation.

After sales fault diagnosis and post repair verification to avoid secondary faults and reduce downtime losses.

Verify the performance recovery of old equipment after major repairs, evaluate the remaining lifespan, and ensure construction safety.

3. Maintenance/remanufacturing enterprises (pre repair diagnosis/post repair acceptance)

Fault location before maintenance (such as internal leakage, insufficient pressure, and decreased efficiency), and precise development of maintenance plans.

After maintenance/remanufacturing, conduct full performance acceptance to ensure that the indicators meet the standards and provide quality assurance basis.

Batch old parts performance screening, distinguishing repairable and scrapped parts, reducing costs.

4. Research institutes/testing institutions (scientific testing/standard certification)

Research on the basic characteristics, fatigue life, reliability, and environmental adaptability of research and development centers in universities and enterprises.

Third party testing institutions provide product certification and quality arbitration, and issue authoritative testing reports.

Simulation testing of extreme working conditions such as high pressure, low temperature, and impact in military and aerospace industries.

5. Specialized equipment fields such as ships, coal mines, and metallurgy

Testing of hydraulic pumps/motors for ship deck machinery, servos, and anchor machines to meet the requirements of classification societies.

Testing of coal mine comprehensive mining equipment, hydraulic supports, and tunneling machine components to ensure underground safety.

Calibration of hydraulic components for metallurgical rolling mills, continuous casting, and lifting equipment to adapt to high temperature and heavy load conditions.
