(1), shaft sleeve sleeve does not extend many leaks sealed box, so to determine the source of the leak is very difficult. Leak bushings are generally stable, while the sealing surface leakage often increase or decrease. After sealing surface leakage, the surface uneven, but sometimes the run to the status quo ante. (Do not rush to overhaul sometimes can be a period of observation to say) (2), if the seal is surrounded by moist, but do not see the leak. This centrifugal force generated when starting operation of the pump so that the leaked liquid back into the sealing surface, since a barrier. And from the flange or connector on the pump leaked liquid drip packing box. (3), to make the thermal expansion in the metal splice member graphite ring loose, it may be due to low temperature so that the O-ring loss of elasticity, resulting in leakage. (4), flushing pressure fluctuations can cause seal failure, flushing pressure must be higher than the number of the seal chamber pressure, to enable pre-installed in the pump solenoid valve and delay switch ensures rinse any residue before the pump start or stop after punch clean the mechanical seal, such as the use of quenching method to control the temperature, must maintain a pressure seal chamber. (5), if the cooling spacer is a layer of precipitated scale ISG200-400B mechanical seals, we can install a graphite liner in the bottom of the seal cavity, the use of its thermal barrier to solve these problems. (6), leaking heat exchanger fouling is often hampered by cooling the surface heat transfer ISG200-400IC pipeline pumps, fluid flow inside the cooler on speeding, or the direction of the heat exchanger installed backwards. 9, the installation process will never agree with something directly beat sealing elements, when demand beat, it is necessary to use special things were beat, to prevent damage to the sealing element. Installation should seal gently to avoid damaging the seals. 10, when the gland bolts should be tightened evenly to prevent deflection gland section, check the points with a feeler or special tools, the error is not greater than 0.05 mm. Check the gland and the shaft or sleeve diameter with the gap (and concentricity), must ensure uniformity around, checking with a feeler points tolerance is not greater than 0.10 mm. 11. When installing stationary ring, the first stationary ring seal trap after the stationary ring back, and then into a sealed cover. Pay attention to the maintenance section of the stationary ring, including the vertical section of the stationary ring and cover the middle line, and the back of the stationary ring groove targeting anti-anti-rotation pin, but contact with each other and not allow anti-rotation pin slot. Make sure to install static ring gland or with a plane parallel to the back cover and seal in place. Should be kept flexible and mobile ring after installation, after the ring is pressed against the spring should be able to automatically bounce back.
