Operating Pressure and Rated Pressure
Pressure
Pressure in fluid mechanics is a very central and fundamental concept that describes the normal force per unit area exerted by a fluid (liquid or gas). Understanding pressure and its properties is essential for analyzing fluid behavior.
Working Pressure
The working pressure (Operating Pressure) refers to the actual operation of the equipment in the process of real-time generated fluid pressure value.
Rated Pressure
The rated pressure is the safe pressure limit set by the equipment manufacturer in a spraying system, representing the highest continuous pressure that the equipment is allowed to withstand under long-term operating conditions.
In high-pressure misting system, the system fittings have a pressure limit. Excessive pressure can cause the accessories or mist nozzles to leak water.
- nylon tube: 90bar/1300psi
- PE tube: 70bar/1000psi
- Stainless steel tube: 120bar/1750psi
- Brass mist nozzle: 80bar/1000psi
- Stainless steel nozzle: 120bar/1750psi.
Rated pressure is the highest pressure boundary for long-term stable operation of high-pressure misting system, the working pressure must be lower than the rated pressure, exceeding this value will lead to seal failure or structural damage.
