How to choose the auxiliary device of mechanical seal for agitator

16/11/2023
The auxiliary devices of mechanical seal s for agitators should be chosen as follows:
1.Thermostat
(1) In short, in order to improve the stability of the stirring shaft support, reduce the working temperature of the sealing chamber of the mechanical seal, and improve the performance of the mech seal, a thermostat should be selected.
(2)XT and LT thermostat types suitable for single mechanical seals (see the figure below).

(3)CT type thermostat suitable for double mechanical seal (see the figure below, it can also be integrated with the mechanical seal).
2.Circulation protection system
(1)Classification of circulation protection systems:
1)A circulation system - GCL type balance tank thermosiphon process;
2)B circulation system - GDL type balance tank forced circulation system;
3)C circulation system - open circulation system;
4)D circulation system - D04-17 type hydraulic pump station forced circulation system.
(2)Circulation system flow chart (see Figure below)
The G-type balance tank is a balance tank used in conjunction with the mechanical seal A and B circulation systems of the agitator.

 4. D04-17 hydraulic pump station The D04-17 hydraulic pump station is a hydraulic oil supply device specially designed for the "D circulation system" of the agitator mechanical seal. It has the functions of lubrication, temperature regulation, pressure regulation, filtering out impurities, etc., and can ensure the stability and reliability of the double mechanical seal. It operates on the ground.
