498 plate heat exchanger rubber pads are prone to leakage, fracture, aging, deformation, etc. after long-term use or without regular maintenance. Once the user finds these conditions, he must replace the rubber pads in time to avoid Cause more serious consequences. At the same time, users should clean the internal rubber pads regularly when using the plate heat exchanger daily, which can prolong its service life and reduce the occurrence of failures. Next, the editor will talk to everyone about the replacement and cleaning steps of plate heat exchanger rubber pads: As the application field of plate heat exchangers continues to expand, there are different temperature, pressure and corrosion resistance for different media and processes. Claim. It is obviously impossible to use a 'universal' gasket to adapt to all situations. Instead, gaskets of different materials should be used for different situations. The commonly used gasket cross-sectional shape is hexagon. Commonly used gasket types are natural rubber, neoprene, nitrile rubber, EPDM, silicone rubber, fluororubber, asbestos fiberboard, etc. If the gasket of the plate heat exchanger is in use, it should be replaced in time if it leaks, breaks, or ages. Replacement should be carried out in the following order. Remove the used gasket. When disassembling, make sure that there are no scratches in the gasket groove. Use acetone, methyl ethyl ketone or other ketone solvents to remove the residual glue in the gasket groove. Wipe the gasket groove and gasket with a clean cloth or cotton yarn. Spread the adhesive evenly in the gasket groove. Attach a clean new gasket to the board. The plate with the gasket should be placed in a flat, cool, and ventilated place to dry naturally for 4 hours before installation and use. The old rubber pad removal and cleaning process The plates are generally cleaned by hand and chemical methods, and must not be removed with a sharp tool to prevent scratching the plates. Correct installation and maintenance are an important part of ensuring the safety and efficiency of the heating system. For example, it is different whether the herringbone corrugated plates should be bonded or snap-on gaskets. The use of snap-on gaskets can effectively prevent the corrosion of the plates by the chloride ions that may be contained in the glue, and the equipment is disassembled and assembled More convenient. However, because the plate heat exchanger has a small flow cross-sectional area, if it is not maintained in time, it may become blocked due to fouling, which will affect the use and normal operation of the equipment. In addition, a gas spray gun can also be used for heating, but the interval between the flame and the bottom of the plate should be strictly controlled to 10-15cm, and more attention should be paid to the aluminum alloy plate. The above is the description of the replacement and cleaning steps of the plate heat exchanger rubber pad, I hope it will be helpful to you.
