The seal gasket is a small part of the plate heat exchanger, but its role can not be ignored. In daily operation, everyone should pay attention to this vulnerable part and learn scientific maintenance.
The main factors that affect the service life of the gasket are: whether the working mode of the plate heat exchanger is continuous; the heat dissipation medium and the corrosiveness of using the cleaning agent; the maximum working temperature; the natural aging and whether the pressure is too large or uneven. .
The softening of the gasket is related to the pressure and temperature. Once the gasket is aged and loses its elasticity, the plate heat exchanger will leak. In order to solve the dripping phenomenon caused by aging, the bolt of the combined plate cooler can be tightened again. The adjustment of the pressing force of the elastic gasket between the heat exchangers can solve the drip problem, because the cooler of this function generally gives the maximum and minimum stress.
For the new heat exchanger chip set, the minimum allowable stress should be used for connection and fixing. Depending on the number of heat exchanger plates per group, the tightening force of the heat exchanger can be adjusted one or more times. When tightening, the nut can be used. Screw in 3mm, and always pay attention to the stress of the adjusting piece during the tightening process. In order to prevent dripping, the tightening force can only be adjusted for the plate coolers without working pressure, and it should be carried out indoors.
