Residual oil pump is a kind of gear pump, the mechanical seal fault device and discussion Mechanical seal, also known as the end seal, he is by the pressure of the spring and sealing medium in the torsion ring and static contact appearance of the appropriate clamping force , Is the two face closely fit. Adhere to a layer of extremely thin film between the end face, the media through the resistance when large, to prevent leakage of liquid, so as to achieve the goal of sealing, at the same time moving ring and stationary ring smooth effect. Well adjusted to complete without leakage. The characteristics of mechanical seals: Residual mechanical seal pump Disposal and Discussion The main advantage of mechanical seals is sealed firmly in a cycle of use, little leakage; long life expectancy, the general can use your Excellency 5 years; long maintenance cycle. However, the mechanical seal structure is complex, built-in, repair mechanical seal often stop the pump to stop the heavy workload. Therefore, to ensure the reliable mechanical seal work, delay the use of mechanical seals and life expectancy is very important. Mechanical seal in daily operation, prone to a lot of problems. Mechanical seal to attack the primary problem is excessive leakage and temperature is too high, touch the mechanical seal gland, if you can not stay on the show that the temperature is too high. Leakage on each side should not exceed 60 drops / min. If into a linear flow, then clarify the leakage is too large, can certainly look at the operation; if out of fuel injection, should immediately shut down inspection.
