Note On Leakage Of Internal Gear Pumps
2020年3月16日What are the reasons for the sudden leakage of the internal gear pump during normal operation?
The main reasons for the sudden leakage of the internal gear pump during normal operation are:
1, the actual output of the pump is too small, a large number of medium pumps circulate in the pump, heat accumulates, causing the medium to vaporize, leading to seal failure,
2, Evacuation, cavitation or prolonged pressure, leading to seal failure,
3.Corrosive, polymerizable, and cementitious substances increase in the medium,
4.The return flow is too large, causing the bottom of the suction tube side container (tower, kettle, tank, pool) to rise and damage the seal.
5, the working conditions change or adjust frequently,
6.For long-term outages, there is no manual cranking when restarting, and the sealing surface is damaged due to friction.
7, the ambient temperature changes dramatically,
8, sudden power failure or shutdown, etc., the centrifugal pump leaks suddenly during normal operation. If it is not found in time, it will often cause a major accident or loss. It must be taken seriously and effective measures taken.
