Regulating the cooling water of plate heat exchanger can reduce the temperature

The plate heat exchanger in the lubrication system is an important part of the steam turbine device. Because the oil absorbs the heat generated by the friction at the bearings during the circulation process, the temperature increases continuously, which is the basis for the operation of the unit. The oil temperature must be controlled within the specified range (no more than 60-65 ℃ and no less than 35-40 ℃).

It will also reduce the service life of the lubricating oil. Too low temperature will increase the viscosity of the lubricating oil, increase friction and labor consumption, and even cause machine vibration. Therefore, the plate heat exchanger is used to reduce the lubricating oil temperature by adjusting the cooling water flow.

Under what conditions can the heat exchange unit not operate

There are many application industries of heat exchange units, which may cause misunderstanding that there are no restrictions on the use of heat exchange units. Although the application range of heat exchange units is wide, there are also restrictions. Let's talk about the condition under which the heat exchange unit cannot operate.

1. The heat exchange unit and external iron box structure are seriously deformed.

2. The damage of heat exchange unit and pipeline causes fire or cannot be handled urgently.

3. Abnormal phenomena occur in the system during startup and shutdown, endangering the safety of the equipment.

4. Other emergencies endangering personal safety and heat exchange unit safety.
