I don’t understand the installation of this machine seal flushing
Thread Content
This is the first time I have seen the installation of a pump machine seal flushing line. It usually goes out from the pump outlet and goes in to the machine seal for flushing. How effective can it be to directly pull out the machine seal and then go in to the machine seal for flushing? From the machine seal, how much is the amount of flushing oil? After mechanical sealing and decompression, to what extent can the flushing effect be achieved? Want an explanation?
It should be the PLAN23 solution, a small circulation in the sealed cavity, often used for high-temperature water.
The picture is incomplete, it should be the PLAN 23 plan. The medium temperature is high and cooled before flushing the machine seal.
Plan 23 is suitable for high-temperature working conditions. The machinery generally has a pumping structure to circulate the medium.
Plan 23, there should be a pump effect wheel inside, and the height difference between the external heat exchanger may have some thermal siphon effect.
The correct answer on the 3rd floor is that the heat exchanger above cools down the temperature of the medium and then flushes it. Because the medium temperature is very high, we use it in boiler circulating water, a medium with a temperature of 250 degrees.
The hard pipe carries the medium, and the flexible pipe carries the cooling water.
There is a pumping structure on the pump shaft to achieve circulation
