The turbine flowmeter is widely used in many industrial applications, such as petroleum, the chemical industry, medicine, and so on. So it is necessary for us to have a new understanding of the turbine flowmeter.
When the liquid turbine flowmeter is installed, the general strainer is installed at the position of 10DN at the front of the flowmeter. Today we talk about the role of the turbine flowmeter strainer and display issues. For the requirements of explosion-proof products: in order to use the instrument safely and normally, it is necessary to check whether the use environment of explosion-proof flowmeter conforms to the user’s explosion-proof requirements, and in the course of installation and use, should strictly comply with the use of national explosion-proof products requirements, users can not change the explosion-proof system connection, can not open the instrument.
Type selection in the specified range of flow, to prevent Overspeed operation, to ensure the desired accuracy, and ensure normal service life.
Prior to the installation of the flowmeter, the pipe should be cleaned of debris, welding slag, stone, dust, etc. . It is recommended to install a 5-micron sieve upstream strainer for blocking droplets and sand particles.
When the flowmeter is put into operation, the front valve should be opened slowly first and then the back valve should be opened to prevent the turbine from being damaged by the sudden air impact. Add lubricating oil should be operated according to the notice board, the number of times depends on the cleanliness of the temperament, usually 2-3 times a year.
The meter may be damaged by Overspeed of the turbine due to pressure testing, purging, or venting, and by the turbine operating in reverse flow. The flowmeter is not allowed to run freely before opening. Rear cover, change the internal parameters, otherwise, it will affect the normal operation of the flowmeter. Install gaskets carefully to ensure that no protrusions enter the pipe to prevent interference with normal flow measurements.
When the flowmeter is calibrated, the pressure should be collected at the pressure inlet of the flowmeter. When the fluid flows into the flow meter, it is rectified and accelerated by a special integrated rectifier at the Air Inlet.
Because the turbine blade is at an angle to the flow direction of the fluid, the turbine produces a moment of rotation, after overcoming the torque of friction and the torque of fluid resistance, the turbine begins to rotate.
In a certain range of flow rate, the angular velocity of the turbine rotation is proportional to the volume of fluid flow.
