Code for operation and maintenance of plate heat exchanger
Operating rules for plate heat exchanger
If the pressure is not the same as the two media, when the 1 start running. First, slowly open the low pressure side of the valve, and then into the high-pressure side of the valve. The equipment shall be operated under the specified working temperature and pressure. The flow of the heat exchanger is composed of a large number of plates according to a certain process and the technical requirements of the technical requirements of the assembly of large particles or long fibers, 6 when the use of media is not clean. Filters should be installed at the entrance. Reduce heat transfer effect. 82o90o hot water for 1020 minutes of disinfection, the 4 piping system should be equipped with the air valve should be discharged after opening the air to prevent the equipment to stay in the air.
Working principle of plate heat exchanger
The movement of the fluid along a narrow, curved channel varies from time to time, and the plate heat exchanger is a special function of the corrugated surface of the plate. Resulting in a small flow velocity (Rc=200) aroused strong end, thus speeding up the destruction of the fluid boundary layer, strengthening the heat transfer process, effectively improve the heat transfer capacity. Otherwise, failed to display the best equipment.
Cleaning and maintenance of plate heat exchanger
Water with the media in the direction of the activities of the erosion, the general situation of 1 can not disassemble cleaning. Can be out of debris, but the pressure should not be higher than the working pressure, can also be used on stainless steel without erosion of chemical cleaning agent. Each plate is then removed and washed and then pressed back in the same way as it is not leaking.
The welding wire shall be welded at the welding place, and when the 7 heat exchanger is connected with the pipeline device. It is strictly prohibited to ground wire in the distance, so that the current loop through the heat exchanger and cause damage. The utility model has the advantages of high heat transfer efficiency, small heat loss, compact structure, light weight, small occupied area, convenient cleaning, wide application range, long service life, etc..
