Plate heat exchanger gasket for the machine is a very important component, but because it has a certain degree of elasticity, after a long period of time, there will be a lack of elasticity, stiffness, aging problems, so that the machine has a great impact on the machine, so we have to work in the day-to-day how to maintain the sealing gasket, so as to prolong its service life? The following factors will have a great impact on the service life of the elastic gasket.
1, the heat exchanger's way of working on the gasket has a certain impact, if it is a continuous way of working, then it will make the gasket for a long time in the working state, accelerating the speed of aging, if it is not continuous way of working, then there will be a certain role in the protection of the gasket.
2, if there is no irregularity in the usual operation, the sealing pad will also appear spontaneous combustion aging, this time is mainly and pressure, temperature has a relationship between the sealing pad loss of elasticity, the machine will appear dripping, so the need for the elasticity of the sealing pad between the adjustments, so as to solve the problem of dripping caused by the aging of the sealing pad phenomenon.
3, in the plate heat exchanger work will often produce too much pressure, or because of some unbalanced pressure and lead to elastic gasket stress is relatively large, which will also shorten the service life of the gasket.
4, the choice of different media, for the machine's heat dissipation has a great impact, in order to better protect the machine and the gasket, we are in the choice of media, to choose those with a better heat dissipation effect of the solution; in addition to the usual cleaning and care of the cleaning agent used also has a certain relationship, if the corrosive nature of the cleaning agent is too strong, then it will be corrosive on the gasket, and therefore in the purchase of the time to select Those on the machine itself will not produce harm to the cleaner.
5, in the heat exchanger work if the pressure is too high or the working temperature is too high, it will also make the gasket is greatly affected, making it premature hardening, loss of the original elasticity, resulting in the heat exchanger can not work normally.
6, usually in the use of the time to pay more attention to the gasket is not a loose situation, in addition to the heat exchanger in each year at least once a year need to carry out the overall inspection and repair.
Plate heat exchanger, although more durable compared to other heat exchangers, but in the use of time is too long or some irregularities in the operation of the sealing ring will occur after deterioration, stains adhere to other reasons, so that the machine loses the original high efficiency performance, so we have to carry out regular maintenance to ensure that it has the best state.
