How many kilograms of pressure is allowed in a sealed storage tank?
Thread Content
Sealed storage tanks develop pressure over time; under normal conditions there should be no pressure. When the pressure rises to several kilograms, it’s necessary to replace the mechanical seal of the pump
There are vent pipes at the top on our side; I haven’t heard of any increase in pressure. However, the internal seals are leaking, which causes the liquid level to rise. This happens frequently with several pumps. It’s better to wait and see what other experts have to say
Under normal conditions in the Plan52 system, the set value for pressure alarms is generally around 0.8–1 bar
It mainly depends on the speed of change; with long-term use, there might be some leakage, but it should not be a big problem
Allow a small amount of leakage; the drain valve on the buffer tank is functioning properly!
Generally, the filter needs to be replaced when the liquid level rises too quickly, or when the pressure exceeds 2 kilograms.
A tank also constitutes a small pressure vessel, and the pressure it generates is not a problem for mechanical seals; if such seals were to leak, it would have been detected through level or pressure alarms long ago
The torch line is normally open. If the liquid level in the buffer tank rises too quickly, the machine seal needs to be replaced
An increase in pressure indicates a seal leak, and the seal should be replaced promptly.
