Can plans 52, 53A~C be used separately?

This post was last edited by longkui1990 on 2018-5-9 17:08. So far, the pumps I’ve seen have not used Plan 52, 53A–C alone; usually it’s numbers like 02, 11, 21 combined with Plan 52, 53A–C I’d like to ask the experts what the reason is? Thank you
That’s something I see far too little of. . . Then why can’t the other three be used alone?
PLAN53A, 53B, and 53C can all be used individually
No, many of them are used separately
It’s just that my horizons are too narrow. . .
What are the advantages of using in combination compared to using alone?
The purpose of the sealed flushing scheme is to provide a better environment for the mechanical seal. This can be divided into many specific effects. Rinse to dissipate heat. The heat generated by the liquid seal must be controlled. This can be achieved by flushing the sealing chamber with a liquid to carry away heat and control temperature rise. Lower the liquid temperature. In some cases, the liquid temperature is too high, affecting the sealing performance. In such cases, the temperature must be reduced to improve the properties of the liquid. Change the pressure in the sealing chamber. In some cases, it is necessary to increase or decrease the pressure in the sealing chamber to improve performance. This can be achieved by suppressing evaporation or reducing the thermal load on the seals. Cleaning process liquid. If the process fluid contains inappropriate solid particles or contaminants, it is necessary to clean the fluid inside the sealing chamber. In extreme cases, it may also be necessary to supply a clean liquid from outside the sealing system. Control the atmospheric side of the seal. Since the process liquids are in contact with the atmosphere, they may dry out, crystallize, or coking. It is very important to prevent interaction with the atmosphere to avoid adverse effects on the sealing performance. Capture and/or prevent leaks. The flushing scheme can provide a method to prevent leakage into the atmosphere. Moreover, they can also provide a safety backup for the primary seal. This will provide users with the opportunity to operate for a short period of time in the event of a seal failure, so as to shut down the equipment more systematically. Detect leaks. A pipeline layout diagram can be selected to enable the measurement of leakage amounts and the monitoring of sealing performance. Provides a liquid other than the process fluid for sealing the environment
They can all be used individually, depending on the characteristics of the medium
53A can be used alone completely.
