The Micro-channels plates for Heat exchanger must not open unnecessarily as it has elastomers that can damage during the opening procedure. It recommends that the gaskets evaluate to check their condition after opening. They can show damage that is invisible to the naked eye, causing leakage after closing the exchanger.
To guarantee the normal operation of the heat exchanger, chemical cleaning recommends. The objective of removing residues from the interior of the equipment is important. Moreover, it could impair its proper functioning.
Micro-channels plates for Heat exchanger cleaning are carried out with a chemical solution specially designed for this purpose. Now, let us learn w the advantages of these plates bring to you?
Advantages of cleaning plate heat exchangers:
Hyson provides a complete heat exchanger operation and maintenance manual to guide customers in equipment maintenance. It recommends to comply with local safety rules to avoid injury and damage. It also recommends to take the necessary protective measures according to the nature of your process and even the situation related to the factory.
Hyson's plate heat exchangers specially design and manufacture to operate under various conditions. These conditions are pressure, temperature, flow and type of fluid supplied by the customer.
Some precautions are necessary, such as worrying that the temperature and pressure do not suddenly exceed the specified values. It can occur during system startup or shutdown. These precautions must be observed so as not to cause serious damage to the equipment.
Assembly and Maintenance Course in Heat Exchangers
In this course, check out the best tips and practices for the assembly and maintenance of Micro-channels plates for Heat exchanger, to ensure the best performance, economy and longer useful life of the equipment components:
The demand for plate heat exchangers in the domestic market is constantly growing. Accordingly, the range of offered plate heat exchangers and the number of suppliers are growing. In this regard, the consumer has a need to evaluate both the proposed heat exchangers and suppliers of plate heat exchangers.
There are two main criteria for evaluating a Product:
Let us first dwell on the quality of the offered plate heat exchangers.
Most of the companies offering plate heat exchangers on the domestic market are not manufacturers in the full sense of the word. These are either representations of foreign firms supplying products to our market, or firms that assemble heat exchangers from foreign-made components.
They use pressure plates of their own production. The quality of components (heat exchange plates) of such foreign companies as Alfa Laval, APV, GEA, SWEP is beyond doubt.
But when assessing the quality of a plate heat exchanger, it is not only the quality of materials and components that should be taken into account.
The quality of the offered Micro-channels plates for Heat exchanger should also include the following:
Unfortunately, some suppliers overlook these quality criteria, or even allow themselves to deliberately neglect them.
Domestic suppliers offering plate heat exchangers made on the basis of foreign-made heat exchanger plates usually calculate the heat exchangers themselves using computer programs provided by the plate supplier.
The training in the calculation of plate heat exchangers is carried out, respectively, by a representative of a foreign supplier of plates. Now a trained specialist will use the principles accepted in Europe, but not always suitable for our conditions, when calculating the heat exchanger.
The quality of water in water and heat supply systems, the quality of circulating water, working media in technological systems in our country and the countries of Western Europe are significantly different. In this regard, the European approach to the value of the so-called "safety factor" of a plate heat exchanger is not entirely suitable for our country.
The safety factor is the ratio of the net heat transfer coefficient in a plate Micro-channels plates for Heat exchanger (calculate without taking into account the thermal resistance of pollution) to the calculate one (calculated taking into account the thermal resistance of pollution) minus one:
As you know, from the very first day of operation of the heat exchanger, hardness salts and other substances dissolved in the working media, or in them in the form of suspensions, begin to settle on the surface of the heat exchange plates. The resistance of these deposits to the heat transfer process calls the thermal resistance of the contamination.
Many companies distribute plate heat exchangers in our country. When they calculate heat exchangers, do not take into account the effect of thermal resistance of pollution on the heat transfer process.
Summary
In their calculations and technical proposals for the Micro-channels plates for Heat exchanger to the Customer, the coefficient of thermal resistance of pollution and, accordingly, the safety factor is close to zero.
This means that the inevitable growth of pollution on the heat exchange surface has invited a lot of issues. It comes from the very first days of operation of the heat exchanger. Moreover, the heated medium will under heat and the coolant will undercool, and the amount of heat transfer per unit of time will decrease.
