由两个部件组成，转子流量计一件是从下向上逐渐扩大的锥形管；转子流量计另一件是置于锥形管中且可以沿管的中心线上下自由移动的转子。 The metal float flowmeter consists of two parts. One of the rotor flowmeter is a tapered tube that gradually expands from the bottom to the top; the other of the rotor flowmeter is placed in a conical tube and can move freely up and down along the centerline of the tube. Rotor. When measuring the flow rate of a fluid, the flow meter measures the flow of fluid from the lower end of the conical tube. The flow of the fluid impacts the rotor and generates a force on it.
的浮子中间装有导向杆，浮子可以平稳地在导杆上下运行，减小了浮子的跳动。 The metal tube float flowmeter is equipped with a guide rod in the middle of the float. The float can smoothly run up and down the guide rod, which reduces the jump of the float. However, if the guide rod is bent or the float is slightly deformed, the movement will be limited and the reading will not work. The most likely cause is because the valve is quickly opened or closed quickly, which results in the occurrence of air pockets or water hammer, which causes the float to violently impact in the flow meter, which deforms the float or bends the guide rod. The solution is to do it slowly when opening and closing the valve. The second reason is due to the magnetic coupling and the effect. The long-term high temperature or the use environment is too bad, which causes the magnetic coupling and magnetic properties to drop, and the movement of the float cannot drive the pointer's indication. The other is because a lot of iron powder particles are adsorbed inside the metal tube float flowmeter. The solution is to use a magnetic filter in front of the metal tube float flowmeter to filter impurities such as iron filings and iron powder. The third reason is caused by the deformation of the internal structure of the metal tube float flowmeter. The possible reasons are that the mechanical transmission parts such as the pointer gear are stuck, and the float or liner of the PTFE material is deformed. In this case, only the float and lining can be replaced to solve the problem.
