Some knowledge about plate heat exchanger gasket! The gasket of plate heat exchanger is used as the sealing element between plates of heat exchanger, so as to prevent the plate from leaking. The quality of gasket directly affects the quality and image of heat exchanger. In the HVAC industry, the gasket is mainly rubber products, which is greatly affected by temperature and medium. Therefore, it is greatly affected by formula, uniformity of components and curing conditions during the process of production. The requirements for picture gaskets are as follows: (the following recommendations do not aim at any brand and HVAC Nan Fang does not take a stand) 1. Formula science, must have anti-aging, tear resistance, high resilience characteristics (reduce the reaction force caused by elasticity, plate is not easy to deform). 2. The sealing contact surface is of accurate size and sensitive alarm signal hole. 3. It is free of adhesive structure and easy to disassemble. Brand of gasket: the manufacturer of rubber strip recognized by domestic users: 1. Domestic brand: Wuhan Parker (well recognized in Beijing market), Xi'an Lianyi, Qidong, Jiangsu, etc. 2. Foreign brands: DuPont, USA, etc. Gasket positioning form: 1. Adhesive type gasket 2. Adhesive free gasket: selection of hanging and clamp type gasket: 1. See the following table for temperature of medium: Picture 2 The application area heating system picture of the corrosive plate heat exchanger in the field of HVAC, the picture of the cogeneration system picture of the geothermal water heating system, namely, the hot domestic hot water system, namely the heat type feature, can ensure that the users have hot water supply anytime and anywhere, the system is compact, and there is no need for storage tank, and the large boiler capacity needs a large heat exchanger. Half that is, the hot domestic hot water system, the half of the heat type features a small boiler capacity, a small heat exchanger, easy to grow bacteria in the tank, and additional places are needed to place the tank.
