Hydraulic oil
The suitable replacement period for hydraulic oil in a sealed tank system is 2000 hours, and more often if the hydraulic oil is contaminated with water or other external materials or subjected to abnormal operating conditions.
As a general recommendation, the 10µ inlet oil filter should be replaced every spring or every 1500 hours (whichever occurs first) on a sealed tank system, or in an open tank system with an air filter fill cap. The oil filter should be replaced every 500 hours.
Heat Exchanger
The heat exchanger core and fins are kept clean at all times for maximum cooling and system efficiency, and the exterior of the heat exchanger is checked daily for blockages and cleaned as needed.
Tank:
The tank level and the water present in the oil should be checked daily. If the tank must be filled with oil, filtered hydraulic oil must be used, and all water in the tank must be removed as required.
Application:
Mixer truck: concrete mixer truck, cement mixer truck;
Coal mining machinery: scraper;
Industry: pharmaceutical machinery;
Transport vehicles: road rollers, concrete pump trucks, stabilized soil mixers
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: MF20-21 closed-loop axial piston motor
- Documented Component No.: 02603250203005
- Documented project quantity: 20 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 MF20-21 motor (Component No. 02603250203005), tested at a temperature of 36.5 °C with a power recovery ratio of 10%. Rated displacement is 33.3 mL/rev, maximum continuous speed 3500 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 (%) |
|---|---|---|---|---|---|---|---|---|
| 1337 | 4.3 | 47 | 35.2 | 27 | 3.8 | 3.4 | 89.1 | 100 |
| 1337 | 14.3 | 45.7 | 35.2 | 85 | 11.9 | 10.9 | 91.5 | 97.2 |
| 1336 | 29.4 | 43.9 | 35.2 | 172 | 24.1 | 21.5 | 89.4 | 93.5 |
| 1311 | 4.3 | 47.1 | 35.9 | 25 | 3.4 | 3.4 | 98.3 | 100 |
| 1309 | 18.2 | 45.4 | 35.9 | 109 | 14.9 | 13.8 | 92.2 | 96.5 |
| 1308 | 30 | 44.2 | 35.9 | 181 | 24.8 | 22.1 | 89.1 | 94.1 |
Charge pressure: 1.5 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 is maintained through product identification, performance records and interface verification.
- Product model and unit identification
