QHTLFX Rotary Steam Flow Meter - Turbine Flow Meter

QHTLFXRotary turbine steam flowmeterDetailed information:
The rotary rotor steam flowmeter is mainly composed of three major components: throttling fluid, damper, and indicator. It is a differential pressure diversion principle instrument. After the measured medium steam enters the throttling fluid of the flowmeter, a part of it passes through the throttle orifice plate of the main pipeline, and a part flows through the diversion pipe through the jet nozzle, and is sprayed onto the impeller, forming a torque on the impeller, which drives the wheel shaft to rotate. Damping blades are installed at the lower part of the wheel shaft and installed in the damping chamber filled with damping fluid, which restricts the rotation of the impeller. Therefore, its speed is much slower than that of steam injection. Therefore, the impeller can effectively absorb the function of steam injection speed, so that its rotation speed corresponds to the torque and damping torque caused by steam injection, and forms a certain quantitative relationship. The speed is directly proportional to the flow rate
The measured steam flows through the flowmeter body: it is throttled by an orifice plate, and under the action of the front and rear pressure difference, a part of the steam enters the splitter pipe nozzle through the nozzle to form a jet, which drives the rotor shaft to rotate with the upper wing wheel. There are two damping blades at the lower end of the rotor shaft that perform damping rotation in the damping chamber filled with damping liquid, so that the wing wheel can fully absorb the kinetic energy of the jet. When the rotational torque of the wing wheel is balanced with the damping torque, the rotational speed of the wing wheel is proportional to the mass flow rate of the measured steam flowing through the flowmeter. Through correction and division, the actual flow rate of accumulated steam is reflected by the indicator dial
