What problems should I pay attention to when buying orifice plates?

When buying orifice plates, we must first know the minimum flow rate, pressure, pressure drop, installation position and safe displacement of the main pump, and then analyze and select them according to the use situation.

The principle of orifice plate is that when the fluid flows in the pipeline, the pressure of the fluid decreases and the energy is lost due to the local resistance of orifice plate, which is called throttling phenomenon in thermodynamics. This method is simpler than using regulating valve, but it must be chosen properly, otherwise, the liquid is easy to cavitation and affect the safe operation of the pipeline. Before buying orifice plates, determine the choke pressure difference Δ p, orifice plate series and orifice plate pressure drop, and calculate the orifice plate pressure difference; Determine the aperture of the orifice plate again and calculate the aperture of the orifice plate. This is very important. The calculation must be accurate to ensure a reasonable choice.

I saw that Wuhan Yangluo Electromechanical Metallurgical Machinery Co., Ltd. produced orifice plates with patent certificates. Interested parties can call 027-89708339 for consultation.

I hope the above information can help you. ?
