The plate heat exchanger manufacturer will show you the structure of the plate heat exchanger?

Through this period of understanding, I believe you are no stranger to plate heat exchangers, but these contents are not enough for customers who want to further understand the relevant knowledge of this product. Today, Xiaobian will share with you the knowledge about the cooling mode of plate heat exchanger, hoping to attract your attention and let you have a deep understanding of plate heat exchanger. In this way, when purchasing and using plate heat exchangers, we can also know well and take it easy. We hope to inspire and help you. Please see the following specific description: the plate heat exchanger is actually a series of heat exchangers folded from corrugated metal sheets, forming a huge channel between various plates, and heat exchange can be carried out through the plates. How can 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 floor area, convenient installation and cleaning, wide application and long service life. Under the same pressure loss, its heat transfer coefficient is 3-5 times higher than that of tubular heat exchanger, the floor area is one third of that of tubular heat exchanger, and the heat recovery rate can be more than 90%.

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 of the bearing during the circulation process, the temperature rises continuously, so as to ensure the safe and reliable 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.

The plate heat exchanger is composed of many plates. There are four corner holes on the plates for the passage of two kinds of heat transfer liquids. The plates are installed in a frame with a fixed compression plate and a movable compression plate on one side and clamped with clamping bolts. There are sealing gaskets in the grooves around the plates. The sealing gaskets seal the fluid channels and guide the fluid to flow alternately to their respective channels to form heat exchange. The plate and the movable pressing plate are suspended on the upper guide rod and positioned by the lower guide rod, and the rod end is fixed on the support column.
