Details before installation of plate heat exchanger

Release time:

2022-08-01

If sewage is used as a cooling medium, or waste heat from sewage is recovered, or the medium contains particulate solids, an appropriate type of automatic discharge filter or purification device should be installed upstream of the inlet end of the heat exchanger to avoid clogging the plate type For heat exchangers, when the possible pressure of the medium is greater than the high operating pressure of the equipment, a pressure reducing valve and a safety valve should be installed at the equipment inlet.

The following will introduce the details of the plate heat exchanger before installation

Details that should be paid attention to before installing the plate heat exchanger

Plate heat exchanger has the advantages of compact structure, reliable operation, simple and intuitive operation, etc. It is a good high-efficiency and energy-saving product. It is mainly suitable for heating, bathing and air conditioning systems in homes, institutions, factories and mines, hospitals, hotels, schools and other places. , the integral plate heat exchanger can be used for both water-water exchange and steam-water exchange. For the installation of the plate heat exchanger, it is necessary to strictly follow the operation process, otherwise it will be damaged in use, thus affecting the realization of the heat exchange effect. In order to To avoid unnecessary problems before installation, today, let's take a look at the things you need to pay attention to before installation:

1. The plate heat exchanger should be installed vertically: attention should be paid to the equipment during hoisting, hoisting holes can be used, the upper guide rod can be used for hoisting or horizontal hoisting, and there should be enough maintenance space on the installation site.

2. Pipeline assembly: Before piping, check whether the heat exchanger is clamped to the specified size range. If not, clamp it to the specified size first. Considering the convenience of maintenance, the heat exchanger is connected to the pipe with a short joint, and the pressure gauge The thermometer should be installed at the inlet and outlet of the cold and hot medium, and an exhaust valve should generally be installed on the pipe connecting the upper corner hole.

3. If the heat exchanger works above 100, the pipe connection should have an expansion absorption compensation device for thermal stress. For special cases, the inclined device is allowed, but it needs to be fixed.

4. If sewage is used as a cooling medium, or waste heat from sewage is recovered, or the medium contains particulate solids, an appropriate type of automatic discharge filter or purification device should be installed upstream of the inlet end of the heat exchanger to avoid clogging the plate type For heat exchangers, when the possible pressure of the medium is greater than the high operating pressure of the equipment, a pressure reducing valve and a safety valve should be installed at the equipment inlet.

It should be known that the plate heat exchanger is mainly composed of a frame and a plate, and the composition of the plate is also designed by the heat exchanger manufacturer on the basis of long-term research using thin plates and corrugations of different shapes. The composition and structure of the heat exchanger are more complicated for those who do not know it, so if you want to use the plate heat exchanger to make it work better, you still need to master some basic structures of the equipment. The plate heat exchanger is an ideal Heat exchange equipment is composed of a certain corrugated shape, and its heat exchange efficiency is relatively high, so this is one of the reasons why it is loved by many people.

Through the above introduction, we all have a further understanding of plate heat exchangers. We must all observe carefully before installation to avoid minor accidents. If you need to purchase plate heat exchangers, you can contact Our company, okay, let's see you next time.
