The plate heat exchanger is actually a series of heat exchangers with folded corrugated metal sheets, forming giant channels between various plates, and heat exchange can be performed through the plates, then How does the plate heat exchanger adjust the water flow to reduce the temperature?
It has the characteristics of high heat exchange efficiency, small heat loss, compact and lightweight structure, small footprint, convenient installation and cleaning, wide application, long service life and so on. Under the same pressure loss, the heat transfer coefficient is 3-5 times higher than that of the tube heat exchanger, and the floor area is one-third that of the tube heat exchanger, and the heat recovery rate can be as high as more than 90%.
The plate heat exchanger in the lubrication system is an important part of the steam turbine installation. Because the oil absorbs the heat generated by friction in the bearings during the circulation process, the temperature keeps rising, in order to ensure the safe and reliable operation of the unit. The oil temperature must be controlled within the specified range (required that the temperature is not higher than 60-65 ° C and not lower than 35-40 ° C). If the temperature is too high, the bearings and other components may be overheated and damaged. And it will reduce the service life of the lubricating oil. If the temperature is too low, the viscosity of the lubricating oil will increase, the friction work will increase, and even the machine will vibrate. Therefore, the use of plate heat exchangers to reduce the temperature of the lubricating oil by adjusting the cooling water flow.
