Turbine flowmeter belongs to velocity flowmeter, also known as impeller flowmeter. The impeller flowmeter utilizes the proportional relationship between the rotational angular velocity of the impeller placed in the fluid and the fluid flow velocity, and reflects the volume flow rate of the fluid passing through the pipeline by measuring the rotational speed of the impeller. It is one of the more mature high-precision instruments in flow meters. As a manufacturer of Zhejiang turbine flow meters, Lianceturbine flow meterIt generally consists of the following typical five parts:
1. Table body
The material of the watch body is generally steel or cast iron, with flange connections at both ends. Small caliber watches also use threaded interfaces.
2. Components measured
There are precision machined blades on the turbine, which together with a set of reduction gears and bearings form a measuring component. The two high-precision stainless steel self-lubricating bearings supporting the turbine ensure that the component has a long service life. The turbine flowmeter can also use an external lubricating oil pump to lubricate the bearings, but be careful not to over lubricate them.
3. Counter
The counter panel contains the following important information:
(1) Higher working temperature and pressure:
(2) Measurement and small and large flow levels
(3) Product model and number
(4) Explosion proof grade and marking
(5) The equivalent and wiring method of the fluid corresponding to low-frequency or high-frequency pulses.
4. Rectifiers
The rectifier is used to keep the fluid flowing through the turbine flowmeter in a regular state, thereby reducing the adverse effects of disturbances on the metering. High measurement accuracy.
5. Magnetic coupling transmission device
The device separates the counter part in the atmospheric environment from the measured gas and transmits the rotation of the measuring component to the counter.
