Failure mode and use the rubber ring is related to hypertension is usually so pressing ○-ring failure of one of the reasons, when found ○ type hardens into a rectangle or ring when IHF50-32-125A, you need to adjust the amount of compression, otherwise it will fever. It is necessary to understand the use of a synthetic rubber temperature. Synthetic rubber is mostly due to a large circle of swelling caused by chemical attack, they all have some own characteristics, such as fluorine rubber resistant to high temperatures and ethylene, propylene ○-ring used in the petroleum oil will swell, ozone NBR Rubber aggressive role, so nitrile rubber products do not install the motor in the IHF, so the high temperature and chemical corrosion is usually caused by hardening of rubber products, the main reason for the crack. When installing rubber parts are surface nicks and cuts, but also a common cause of seal failure. The signs of the old fixed screw shaft, keyway, spline shaft, sharp shoulder so will damage rubber parts. (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 IHF50-32-200, can observe a period of time 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 IHF50-32-160, 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, 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 scale precipitation, we can install a sealed chamber at the bottom of the graphite liner, the use of its thermal barrier to solve these problems. (6), leaking heat exchanger fouling is often hampered by cooling the surface heat transfer, fluid flow inside the cooler on speeding, or the direction of the heat exchanger installed backwards.
