Rotary steam flowmeter is mainly by the throttle body, damper and indicator of three major components, is a differential pressure - shunt principle instrumentation, the measured medium steam into the flowmeter throttle body, part of the throttle orifice through the main pipeline, part of the shunt pipe flow through the nozzle, jet to the impeller, the impeller to form torque, so that the impeller drives the wheel axis rotating in the wheel shaft is fitted with a damping blade in the lower part of the impeller shaft installed in the damping chamber filled with damping fluid, so that the impeller rotation is constrained, so it rotates more slowly than the speed of steam, therefore, the impeller can effectively absorb the speed of steam spray more than slow, therefore, it can effectively absorb the speed of steam spray more than Filled with damping liquid damping chamber, so that the impeller rotation constraints, so its rotational speed is much slower than the steam jet speed, therefore, the impeller can effectively absorb the steam jet speed function, so that its rotational speed and steam jet caused by the torque and damping torque corresponds to the formation of a certain amount of relationship between the impeller rotational speed and the flow rate is proportional to.
Rotary steam flowmeter is a mass flowmeter for measuring the flow of saturated or superheated steam through pipelines, which can display the cumulative or instantaneous value of steam mass flow on site or by remote transmission. Intelligent temperature and pressure compensation, measurement of superheated steam. The flow meter is equipped with Ⅰ, Ⅱ, Ⅲ throttle orifice plate, can be changed by replacing the throttle orifice plate to change the flow range, the flow meter has a wide measurement range, high accuracy, long life, operation, maintenance and convenient, widely used in petroleum, chemical, light industry and other industrial sectors of the steam flow measurement.
Rotary wing steam flowmeter features.
1, the flowmeter is a mechanical instrument, solid structure, easy to install, use and maintenance. With the measured steam as a power source, without the need for external power source.
2、With three kinds of specification orifice plate, the flow range is wide.
3、It can be easily adjusted after the working pressure is changed; 4、It adopts magnetic connection.
4、Using magnetic connection, good sealing performance.
