Heat pump mechanical seal Precautions

Heat pump according to the conditions of use of the different installation of different forms of mechanical seals , such as the built-in single-ended flat horizontal and non- balanced ,high security cable seals double-end balanced and unbalanced type , externally mounted mechanical seals , etc. Therefore , according to the choice of seals in different forms, its using methods and precautions are also different, generally have the following specific conditions :
1, the general mechanical seal suitable for cleaning medium without suspended particles , on the newly installed piping system should be carefully cleaned reservoir together to prevent solid impurities into the mechanical seal faces .
2, in the crystallization medium using mechanical seals , attention should be cleaned regularly , before the restart after stopping to get crystal mechanical seal clean .
3 , the mechanical seal should be carefully disassemble , prohibited by hand cone, iron and other percussion . Demolition should be clear dirt.
4 , strict inspection ring and the stationary ring for face grinding , does not allow any minor scratches, Pengpo other defects.
5 , the right to adjust the amount of compression springs , making it an appropriate degree of tightness to avoid excessive wear or leakage.
6, there is an external mechanical seal flush , start should be preceded by open cavity filled with fluid sealing liquid is sealed ,adjustable length plastic seals stopping when the first stop the pump, close the seal flush fluid.
