Plate heat exchanger is a highly efficient and energy-saving heat exchange equipment. It has the advantages of high heat transfer coefficient, compact structure, less consumables, various forms, and easy maintenance. It has been widely used in machinery, electric power, metallurgy, chemical industry, textile and beverage. , Urban heating and other industries and fields. The plate heat exchanger is a partitioned heat exchanger composed of a certain number of plates, gaskets and frame plates. Due to the small passage, there is enough space around for regular maintenance and cleaning. So what are the operating precautions before installing the new plate heat exchanger?
(1) The water pressure test should be done at 1.3 times the maximum working pressure for plate replacement. The steam part should not be lower than the steam supply pressure plus 0.3mpa. The hot water part should not be less than 0.4mpa. Keep the pressure under the test pressure for 30 minutes without dropping.
(2) The vertical clear distance from the highest point of the upper attachment (safety valve) of the heat exchanger to the lowest point of the building structure shall meet the requirements of installation and testing, and shall not be less than 0.2m.
(3) The installation height of various valves and instruments should be convenient for operation and observation.
(4) The front section of the plate heat exchanger should leave a space for disassembling the plates, and the clear width of the operation channel of the equipment should not be less than 0.8m.
