Now more and more plate heat exchanger manufacturers, the production of heat exchangers are similar, Qingdao Ruipute is a good reputation in the industry manufacturers, heat exchanger equipment can do five years of trouble-free operation, but in the process of use may fail, Qingdao Ruipute heat exchanger manufacturers tell you how to prevent the plate heat exchanger failure.

1. Seal failure: plate heat exchanger in the rated working pressure within the leakage, in addition to equipment manufacturing factors, mainly with the system pressure and temperature changes rapidly. Shock caused by the instantaneous pressure is often 2 to 3 times higher than the normal pressure, so that the installation of the rubber gasket displacement, resulting in sealing failure. When the temperature changes too quickly, the elasticity of the gasket and sealing preload force does not match, resulting in equipment pressure capacity is lower than the rated design pressure and leakage.

l Preventive measures: try to avoid the impact of the system in operation. Depending on the operating pressure to increase the design pressure of the equipment 1.5-2.0 times. Take other measures to compensate for changes in seal preload. In operation, the temperature and pressure increase process should be as slow as possible.

2. Blockage: plate heat exchanger flow channel gap is small (2.5 to 6.0mm), the diameter is greater than 1.5 to 3.0 two debris easily blocked channel, resulting in equipment failure due to blockage.

l Preventive measures: in the media inlet set coarse filter or flushing device, can effectively prevent the device from clogging and improve the heat transfer effect.

3. Fouling: plate heat exchanger fouling will reduce the heat transfer coefficient, will seriously block the plate channel. Plate heat exchanger plate design has a large number of support contacts, is a solid impurity or fiber easy to gather at the place, easy to make fluid formation local retention and scaling. In addition, the medium of Ca2 +, Mg2 + will precipitate solid formation of scale, scale and blockage of different causes, but the impact is the same.

l Preventative measures: plate heat exchanger should not be used in a dirty or easy to scale the environment. With no softening of the cooling water as a medium, the operating temperature should be controlled below 50 ?.

The main products are: plate heat exchanger, plate and shell heat exchanger, detachable heat exchanger, plate heat exchanger plate, plate heat exchanger adhesive gasket, is a plate heat exchanger direct sales manufacturers, not only the plate heat exchanger price is low, the quality is also completely to the level of the international front-end brand.
