Leakage of mechanical pumps in atmospheric and vacuum distillation units

2017-07-06View Original

Thread Content

If the mechanical seal of the pump in a vacuum distillation unit leaks, and what leaks is gasoline or diesel, could this leakage cause a fire? Please discuss this. Thank you, extra points

A leak in the mechanical seal of a high-temperature oil pump can cause a fire, while a leak of light components will produce smoke that looks like fog; this is quite dangerous.

A large leakage from the residue oil pump is dangerous; a fire must be prevented~

If the ambient temperature is high, it becomes dangerous

Seal leakage is quite dangerous, as a leak in the seal creates gaps. With the seal still in operation, there are periods of partial contact and partial disconnection between its end faces; leakage occurs during the periods of disconnection, while friction during contact generates high temperatures that cause the liquid to vaporize. This reduces the cooling effect of the seal, creating a repetitive cycle. Eventually, friction between the seal’s end faces can result in sparks or static electricity, which may lead to accidents.

Such leaks with a low flash point can catch fire even from friction with air; it is very dangerous

Media with high temperatures, whether it’s light gasoline, medium-grade diesel, or heavy residue oil, will ignite in the event of a leak at the M.S. location~~~ The solution commonly used in China is to introduce medium-temperature sealing oil (heavy diesel) and use PLAN32~~~ However, this approach has its limitations and involves significant operational risks; a more reliable method is to use PLAN32 combined with PLAN53A~~~ But the choice of solution depends on the specific conditions on site;

All our hot oil pumps are 32+53A
