2. Before installation, clean the pipeline connected with it, so as to avoid sand, oil, welding slag and other sundries entering the plate heat exchanger, causing obstruction of the flow passage or damage to the plate. The plate heat exchanger covers a small area and is light in weight. In addition to the volume of the equipment, there is no need to reserve extra inspection and installation space. The thickness of the plate used for heat exchange is 0. 6 ~ 0. 8 mm. When the machine stops, first close the high pressure side medium solenoid valve, and then close the low pressure side medium solenoid valve. In the environmental protection, energy saving today, plate heat exchanger has been widely used in the field of heat exchange, can be used in different process heating, cooling and other aspects, in the energy recovery, also has economic benefits.
When starting up, open the low pressure side medium plunger valve first, and then slowly open the high pressure side medium plunger valve after the medium passes through the plate heat exchanger channel;
3.Check whether the clamping bolt is loose before putting it into use, and if so, tighten it. In recent years, plate heat exchangers have replaced the traditional shell and tube heat exchangers in airports, hotels, commercial buildings and other fields, and have achieved good results.
4.If the medium may often have larger particles of sand or debris, should be in the plate heat exchanger before the configuration of the plant produced by the matching decontamination device. The plate heat exchanger has low fouling coefficient, the fluid violently rolls between plates to form turbulence, and the plate design avoids the existence of dead zone, making it difficult for impurities to deposit and block in the channel.
