Pay Attention To The Composition Of The Detachable Plate Heat Exchanger When Using The Cooler
If you want the plate heat exchanger to be used better, you need to pay attention to a lot of places when using the heat exchanger. The editor of the plate heat exchanger below will introduce some points that you need to pay attention to when using the heat exchanger.
1. Pay attention to prevent the plate heat exchanger from freezing:
When the temperature is lower than zero degrees Celsius, the water inside and outside the plate heat exchanger will freeze, and the volume will increase after freezing, resulting in the expansion and cracking of the plate heat exchanger. Therefore, the installation of the plate heat exchanger must be equipped with a drainage device so that the water in the plate heat exchanger can be drained out when the plate heat exchanger is idle.
2. Treatment of dirt in water:
Solid Dirt: Solids that do not dissolve in water and easily clog pipes and heaters. The blunt fiber cannot pass through the cooler, so try to get rid of it. The particle debris cannot be less than 0.8mm, it is recommended to install a 40 to 70 target power filter. However, the power filter must be regularly maintained.
Materials that are soluble in water. The calcium and magnesium ions in the water will form scales in the ditch under the action of high temperature, which will affect the heat exchange rate of the plate heat exchanger and reduce the performance of the plate heat exchanger. Treatment method to reduce the content of calcium and magnesium ions in water.
Now more and more friends use plate heat exchangers, so do you know the components of detachable plate heat exchangers? Let me introduce to you below.
1. Heat transfer plate
The heat transfer plate is the main heat exchange element of the plate heat exchanger. Generally, the corrugation is made into a herringbone shape. According to the different fluid medium, the material of the heat transfer plate is also different. Most of them are made of stainless steel and titanium.
2. Gasket
The sealing gasket of the plate heat exchanger mainly plays a sealing role between the heat exchange plates. The materials are: nitrile rubber, EPDM rubber, fluorine rubber, etc. Different rubbers are used according to different media.
3. Both ends of the pressure plate a
The pressure plates at both ends are mainly to clamp and press the heat transfer plates to ensure that the fluid medium does not leak.
4. Clamping bolts
The clamping bolts are mainly used to fasten the pressure plates at both ends. The clamping bolts are generally double-ended threads. When the bolts are pre-tightened, the torque of the fixed plate is uniform.
Five, hanger
It is mainly to support the heat exchange plate, so that it is convenient to disassemble, clean and assemble.
