The content of the above article is that the editor introduced the matters needing attention in the use of the all-welded plate heat exchanger. Of course, there are still many things to pay attention to when using it.
At present, fully welded plate heat exchangers are widely used in many industries in China, but it is believed that some friends will encounter many failures when using plate heat exchangers. The company will explain all welding methods as follows. Pay attention to some points when using. I hope it can bring you some good help.
Before using the all-welded plate heat exchanger, check whether the fastening bolts are loose. If loose, tighten the bolts. Therefore, before starting, open all outlet valves of the all-welded plate heat exchanger and close the inlet valve of the heat exchanger. After the pump is started, slowly open the inlet of the heat exchanger and gradually increase the flow and pressure to avoid local impact and damage to the equipment caused by local high pressure. During the operation of the heat exchanger, in order to prevent overpressure on one side, the inlet valves of the cold and hot media of the heat exchanger should be opened at the same time, or the low pressure should be injected slowly, and then the high pressure side should be injected slowly. In addition, it should also be noted that this product is mainly used to control the flow of cold and hot fluids according to the readings of the thermometer of the all-welded plate heat exchanger, so as to achieve the required process parameters and stable operation. Exhaust valves shall be provided in the piping system. After starting, the air in the equipment shall be discharged to prevent the air from staying in the equipment and reduce the heat transfer effect. In addition, if there are large particles of sediment or other debris in the hot and cold, the product should be filtered in advance. It is forbidden to use sewage for hydraulic test and operation, so as not to affect the service life of heat exchanger.
When using the all-welded plate heat exchanger, it should be noted that when the two types of heat exchanger must be larger, the low temperature can be introduced, and then the high temperature can be passed. If the machine is turned off or the power supply is turned off, check the inlet valve immediately. The supporting equipment shall be sealed well, and leakage is not allowed here. Of course, this is mainly due to the premature aging of the lower gasket, so what needs to be done at this time is to turn it off. In addition, it is also necessary to check whether there is corrosion, rust and damage in the interior and all accessories of the all-welded plate heat exchanger. If the above problems do not occur, it can be heated and used normally. Pay attention!!!! Xiaobian reminds you here that if it is used in a special industry, remember to prepare accessories: decontaminator and filter. Of course, this can avoid pipe blockage and water pollution. Of course, it is also necessary to ensure that there is no impurity and check the concentration. In the process of using the all-welded plate heat exchanger, if there is high pressure medium, it means that water seepage has occurred inside.

Will help you solve some problems of the quotation method.
The content of the above article is that the editor introduced the matters needing attention in the use of the all-welded plate heat exchanger. Of course, there are still many things to pay attention to when using it. We will continue to introduce it in the next issue. For other aspects of knowledge, you can see it as long as you pay more attention to the website. Thank you again for reading the article.
