Find the choice of hole diameter and thickness when the preheating wire of the catalytic oil slurry pump is replaced by an orifice plate throttling
Thread Content
When preheating the oil slurry backup pump of my unit, the preheating valve body was worn out many times. Fortunately, it was discovered in time and no accident occurred. Now I want to replace the preheating of the catalytic oil slurry pump with an orifice plate throttling. I would like to ask for your help on the selection of hole diameter and thickness. Thank you all! The outlet pressure of one slurry pump is 1.7MPa and the other is 1.5MPa. Our device has an annual processing capacity of 1.2 million tons.
It is recommended that this issue be checked by a design institute. After all, the size of the orifice plate is related to the flow rate. The flow rate must ensure that the pump is preheated and will not cause the pump to reverse. The opinions are for reference only.
The following data are required: Volume flow rate of the fluid, m3/h Pressure after the first orifice plate, Mpa Pressure drop through the orifice plate, Pa Relative density of the fluid Pipe inner diameter, m Mass flow rate, kg/(m2* s) Viscosity, mPa * s Reynolds number orifice plate flow coefficient
