Before the installation of the plate to clean the pipeline
Heat exchanger manufacturers of high heat efficiency and low heat loss, in the best working conditions, the heat transfer coefficient can reach 6000Wm / 2K, in general working conditions, the heat transfer coefficient is about 3000 ~ 4000WK, is a shell and tube heat exchanger is 3 ~ 5 times, all the fluid through the device can the formation of turbulence in the plate corrugation under the action of heat exchange full. Wide range of products, the highest temperature of up to 180 degrees C, pressure 2.0MPa. The utility model is convenient for inspection and cleaning, and the heat exchanging plate is assembled by clamping the clamping force of the clamping screw, and the plate can be washed and cleaned only by loosening the clamping screw bolt when checking and cleaning. Heat exchanger for a long time, the heat transfer plate surface will produce different degrees of dirt or sediment, thereby increasing the flow resistance and reduce the heat transfer function, the main performance for the import and export pressure gauge pressure difference increases and the cold medium outlet temperature decreases, so the necessary cleaning check.
1, the installation of plate heat exchanger to be reserved around the location of a certain test site.
2, before the installation of the pipeline to be connected with the cleaning, in order to avoid sand, oil, welding slag and other debris into the plate heat exchanger, resulting in obstruction or damage to the flow channel plate. Plate heat exchanger covers an area of small, light weight, in addition to the volume of the device itself, do not need to reserve additional inspection and installation space, the thickness of the plate used for heat exchange is only 0.6 ~ 0.8mm. When the machine is shut down, the solenoid valve of the high pressure side is sealed, and then the solenoid valve of the low pressure side is closed. In exaggerated efficient, environmental protection and energy saving today, upper plate heat exchanger in the field of heat exchange has become increasingly significant, can be used together in the process of heating, cooling and food disinfection, in low grade heat recovery, but also has significant economic benefits.
When the power is turned on, the low pressure side medium plunger valve is opened first, and the medium is filled with the plate heat exchanger channel to slowly open the high-pressure side medium plunger valve;
3, plate heat exchanger, the order of the shutdown:
4, put into use before checking all clamping bolts are loose, if should tighten. In recent years, plate heat exchanger in the airport, hotels, commercial buildings and other fields, has replaced the traditional shell and tube heat exchanger, and achieved good results.
Maintenance and maintenance:
5, if the media may often have larger particles of mud sand or debris, should be in the plate heat exchanger before the configuration of our factory production of the supporting device. Heat exchanger fouling coefficient is low and the fluid in the plate between the severe rolling plate become turbulent, excellent design to avoid the existence of dead time, which is not easy to be blocked in the deposition of impurities channel, ensure the good effect of heat transfer.
