Plate Heat Exchangers Elastic Gaskets

  The softening of elastic gaskets in plate heat exchangers will affect the normal operation,, and there are many factors affecting the softening of elastic gaskets.Plate Heat Exchangers Elastic Gaskets

The softening of elastic gasket is related to pressure and temperature. There will be drip leakage in the heat exchanger when the gasket loss its elastic.

In some products, in order to solve the leakage phenomenon caused by the aging of sealing gaskets, it is allowed to adjust the sealing performance of heat exchangers. That is, tighten the bolts of the plate heat exchanger again. Adjust the pressure of the elastic gasket between the heat exchangers plates. Solve the problem of drip leakage.

  Generally, the allowable maximum and minimum stresses are given on the nameplate of plate heat exchanger. The minimum allowable stress should be used for connection fixation at the new plate heat exchanger. The tightening force of heat exchanger can be adjusted once or more depending on the number of heat exchanger plates in each phe group . The nut can be screwed in for 3mm and the stress of the adjusting plate should be paid attention to during the tightening process. Only heat exchangers without working pressure are allowed. The tightening force is adjusted at room temperature and without working press to prevent dripping.

  The softening factors of the elastic gasket of plate heat exchanger are introduced above. Environmental factors should be paid attention to in normal use, and timely adjustment should be made to avoid some faults and cause unnecessary losses.
