1.Introduction

TSO Seal Water Control and Monitoring System is used to monitor and control the flow and pressure of seal water in seals and

system,will create the best operating environment for seals and maximize the runnability of the process. It’s designed for varies

sealing system(including packing and mechanical seal application) like pump, mixer and agitator.

The system includes a flow test equipment, pipe and joints, can be installed around pump. For seal water’s flow and pressure

automatic control, low flow alarm sensors can be used.
 

2. Working Theory

As showed in Picture 01, filtered cooling lubricating seal water enters the

knob plate then goes into the measuring system. With in the measuring

system there is a transparent flow indicator and a cylindrical floater with a

white ring(flow memory pin). The white ring(flow memory pin) will drift

left when struck by seal water, when the flow keeps stable, the white ring(flow

memory pin) will stay static and point at a fixed scale value.

This stable seal water flows out then and enters the seals and system, which

will achieve the seal and system’s cooling and lubricating.

For double seal application system, seal water can flow back to knob plate,

and the pressure gauge with memory pin will tell the pressure value.

After discharge, the seal water can be cyclic used.
