Factory Production & Inspection Evidence
As the manufacturer, Shandong Highland Hydraulic Seiko Co., Ltd. maintains production and inspection records for the closed-loop axial piston motor used in these drive systems.
- Manufacturer: Shandong Highland Hydraulic Seiko Co., Ltd. (brand: Highland)
- Documented motor: MF22-21 closed-loop axial piston motor
- Documented Component No.: 02603030203003
- Documented project quantity: 60 units
- Closed-loop motor tested and inspection-recorded before release
Evidence type: factory production and product-identification record.
Factory Performance Testing
Factory performance testing is carried out on a closed-loop hydraulic test bench, recording the motor's behaviour at several speed and pressure set points.
The supplied Closed-Loop Hydraulic Motor Test Report documents the MF22-21 motor (Component No. 02603030203003), tested on 2026/3/3 at a temperature of 36.2 °C with a power recovery ratio of 20%. Rated displacement is 69.8 mL/rev, maximum continuous speed 3200 r/min and minimum continuous speed 500 r/min, with a rated working pressure of 35 MPa and a maximum (instantaneous) pressure of 42 MPa.
The test covers a range of operating points rather than a single condition.
Recorded Test Data
The closed-loop report logs the motor's measured values; selected factory-recorded points are reproduced below.
| Speed (r/min) | Pressure (MPa) | Flow (L/min) | Displacement (mL/rev) | Torque (N·m) | Input Power (kW) | Output Power (kW) | Overall Efficiency (%) | Volumetric Efficiency (%) |
|---|---|---|---|---|---|---|---|---|
| 1294 | 5.7 | 92.6 | 71.6 | 78 | 10.6 | 8.8 | 83.2 | 100 |
| 1292 | 16.7 | 90.4 | 71.6 | 206 | 27.9 | 25.2 | 90.3 | 97.8 |
