Cooling Oil Equipment Guide and Usage Instructions
---
I. Equipment Advantages
High-efficiency heat exchange performance
- Utilizes a multi-process restraint design (titanium tube/stainless steel tube), enhancing heat transfer efficiency through intensified turbulent effects, achieving a heat exchange coefficient of 3000~4500 W/(㎡·K) for steam-water heat exchange, significantly reducing the oil temperature in the lubrication system.
Supports closed-loop cooling to reduce water consumption and prevent oil contamination.
2. Strong structural reliability
- Modular housing design (welded/flange connection), supporting axial free expansion to accommodate thermal stresses caused by temperature fluctuations.
- Utilizes dual-sealed structure (O-ring + gasket) to minimize oil-water intermixing risks and extend maintenance intervals.
3. High Adaptability
- Compatible with high-temperature oils (up to 160℃) and low-temperature cooling water (down to 15℃), meeting the needs of various industrial applications.
- Available for custom vertical/horizontal installation; vertical saves space, horizontal has lower pressure drop, and strong shock resistance.

Section 3: Installation and Maintenance Precautions
Installation Requirements
- Basic Treatment: The deviation of horizontal levelness should be controlled ≤3mm/m, and a thermal expansion gap (≥5mm/m) should be reserved for sliding supports.
Pipe specification: Oil line piping length ≤ 5 meters, elbow quantity ≤ 3, to avoid excessive pressure loss.
2. Initiate Debugging
- First-time operation requires flushing of the piping (oil side + water side) to prevent slag from clogging the bundles.
- Stage-by-stage pressure increase (oil side pressure rise rate ≤ 0.1 MPa/min), simultaneously monitor leakage at sealing points.
3. Routine Maintenance
- Key Points Inspection: Monthly check for tube scaling condition (requires cleaning if pressure difference ≥ 0.05 MPa), quarterly verification of O-ring elasticity.
- Cleaning Cycle: At least one chemical cleaning (citric acid solution circulation) per year, and scale removal by high-pressure water jet on the bundles every 2 years.
4. Troubleshooting
- Oil-water mixing: Immediately shut down, inspect for any damage to the seals, and replace gaskets if necessary.
- Heat Exchanger Drop: Investigate insufficient cooling water flow or tube bundle blockage, and prioritize reverse flushing the water-side piping.
