Factory Production & Inspection Evidence
The drive systems are built at the factory of Shandong Highland Hydraulic Seiko Co., Ltd., where unit identification and inspection records form part of normal production practice.
- 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
The identification system allows a delivered unit to be matched to its production and test documentation.
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 following points were recorded during the closed-loop test run of the documented unit.
| 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 |
| 1288 | 31.1 | 89 | 71.6 | 377 | 50.9 | 46.1 | 90.7 | 96.6 |
| 1294 | 5.5 | 92.6 | 71.6 | 68 | 9.2 | 8.5 | 92.1 | 100 |
| 1292 | 16.3 | 90.9 | 71.6 | 197 | 26.7 | 24.7 | 92.6 | 98.3 |
| 1291 | 31 | 88.9 | 71.6 | 369 | 49.9 | 45.9 | 92.1 | 96.2 |
Charge pressure: 1.4 MPa. Values are reproduced from the original test record and should be read together with the test bench's measurement and calculation method.
Quality Control & Inspection
Quality control relies on unit identification, test-bench verification and the engineering specification.
- Product model and unit identification
- Closed-loop hydraulic performance testing
- Pressure and speed verification
- Flow and displacement recording
- Torque and power measurement
- Overall and volumetric efficiency recording
- Engineering interface verification
In the supplied test record the run is signed by an operator and an auditor (Operator 003, Auditor 002). The product documentation also states that units are produced under a strict quality-control system, and that any defective pump or motor is inspected before a response is issued.
