【Q&A Question 155】September 22, 2016: How to determine if there is internal leakage in the pump’s seal oil? The answer key will be available after responding; scoring is based on addressing the key points. As the level of the seal oil in the tank drops, the pressure of the seal oil in the internal leakage pump may fluctuate. .
As the level of the seal oil in the tank drops, the pressure of the seal oil in the internal leakage pump may fluctuate.
Check whether there are any changes in the pressure and flow rate of the seal oil compared to normal conditions.
Loosen the oil inlet of the rod side chamber to apply pressure to the rodless side chamber, and check whether oil flows out; if it does, there is an internal leak. Conversely, check for internal leaks in the rod side chamber
The normal outlet pressure cannot be achieved, resulting in the pump body heating up, making noise, and operating unevenly
Check whether the liquid level in the buffer tank outside the sealing flushing system is rising or falling.
The pressure cannot be maintained; the pressure of the sealing oil has decreased
White oil tank pressure: an increase in liquid level, as well as oil immersion lubrication, can lead to changes in the lubricating oil properties, temperature fluctuations, and changes in bearing temperature
As the level of the seal oil in the tank drops, the pressure of the seal oil in the internal leakage pump may fluctuate.
