What is the vacuum pressure of the turbine oil purifier?

The vacuum pressure of a turbine oil purifier is a key parameter in the operation of the equipment. It directly affects the filtering effect, especially the dehydration and degassing performance. Generally, the vacuum pressure range of a turbine oil purifier is between -0.08 MPa and -0.098 MPa (i.e. -600 mmHg to -735 mmHg), and the specific value depends on the design and operation requirements of the equipment.

1. The role of vacuum pressure

- Dehydration: Under vacuum conditions, the boiling point of water in the oil is lowered, making it easier to evaporate and be pumped out by the vacuum pump.

- Degassing: The vacuum environment helps to separate dissolved gases in the oil and improve the insulation and lubrication properties of the oil.

- Improve filtration efficiency: Under vacuum conditions, the fluidity of the oil is enhanced and the filtration speed is accelerated.

2. Typical range of vacuum pressure

- General range: -0.08 MPa to -0.098 MPa (-600 mmHg to -735 mmHg).

- Optimal range: -0.095 MPa to -0.098 MPa (-710 mmHg to -735 mmHg), at which the dehydration and degassing effects are the best.

3. Factors affecting vacuum pressure

3.1 Equipment performance

- Vacuum pump capacity: The vacuum pump's pumping speed and ultimate vacuum directly affect the system's vacuum pressure.

- Sealing: Poor equipment sealing will cause the vacuum pressure to ｄｒｏｐ, affecting the filtering effect.

3.2 Oil Characteristics

- Oil viscosity: High-viscosity oil requires a higher vacuum pressure to achieve the ideal dehydration and degassing effect.

- Contamination level: When the water and gas content in the oil is high, a higher vacuum pressure may be required.

3.3 Environmental conditions

- Ambient temperature: In a low-temperature environment, the efficiency of the vacuum pump may be reduced, resulting in insufficient vacuum pressure.

- Altitude: The atmospheric pressure is lower in high altitude areas, which may affect the performance of the vacuum pump.

4. Adjustment of vacuum pressure

- Vacuum pump control: Control the vacuum pressure by adjusting the operating parameters of the vacuum pump (such as speed or power).

- Vacuum gauge monitoring: Use a vacuum gauge to monitor the system pressure in real-time to ensure that it is within a reasonable range.

- Valve adjustment: Control the pressure by adjusting the valve of the vacuum system.

5. Precautions

- Avoid excessive vacuum: Excessive vacuum pressure may cause excessive evaporation of oil or damage to the equipment.

- Regular maintenance: Check the vacuum pump and seals regularly to ensure the normal operation of the system.

- Safe operation: When adjusting the vacuum pressure, pay attention to the operating status of the equipment to avoid accidents.

Summary

The vacuum pressure of the turbine oil purifier is usually controlled between -0.08 MPa and -0.098 MPa, and the optimal range is -0.095 MPa to -0.098 MPa. By reasonably adjusting the vacuum pressure, the dehydration and degassing effects of the equipment can be significantly improved to ensure the quality of the turbine oil. In actual operation, appropriate adjustments must be made based on oil characteristics and equipment performance, and attention must be paid to equipment maintenance and safe operation.
