的测量准确、必须正确地选择安装位置和方法、对直管段的要求： In order to ensure the accurate measurement of the turbine vortex flowmeter , the installation position and method must be correctly selected, and the requirements for the straight pipe section:
The flowmeter must be installed horizontally on the pipeline (the pipeline is inclined within 50), and the axis of the flowmeter should be concentric with the pipeline axis during installation.
Flow must be consistent;
应安装在便于保修、无强电磁干扰与热辐射的场所 The flow meter should be installed in a place that is convenient for warranty and free of strong electromagnetic interference and heat radiation.
Requirements for installation welding: The user is equipped with another pair of standard flanges for welding on the front and rear pipes; welding with a flow meter is not allowed.
Before installing the flowmeter, clean the slag and other garbage in the pipe strictly. It is best to use an equal-diameter pipe (or bypass pipe) instead of the flowmeter to blow
Sweep pipes to ensure that the flowmeter is not damaged during use;
When installing the flowmeter; the gasket between the flanges must not be recessed into the pipeline
Flowmeter grounding requirements. The flowmeter should be reliably grounded and cannot be shared with the ground wire of the strong power system.
Requirements for explosion-proof products;
In order to ensure the safe and normal use of the instrument, it should be checked whether the use environment of the explosion-proof flowmeter is in accordance with the user's explosion-proof requirements.
In the process of installation and use, the national explosion-proof product use requirements should be strictly observed. The user must not change the connection method of the explosion-proof system.
Do not open the meter at will, pay attention to safety:
Requirements for the external environment:
The flowmeter is best installed indoors. When it must be installed outdoors, it must be protected from sun, rain and lightning to avoid the impact.
The effect of its life.
Requirements for impurities in the medium:
的使用寿命，应在流量计的直管段前安装过滤器。 To ensure the service life of the flowmeter, a filter should be installed before the straight section of the flowmeter.
The selection is within the specified flow range to prevent overspeed operation to ensure that the desired accuracy is obtained and the normal service life is guaranteed.
Before installing the flowmeter, clean up the debris in the pipeline: debris, welding slag, stones, dust, etc. It is recommended to install a 5 micron screen hole upstream.
Filters are used to block droplets and sand.
When the flowmeter is put into operation, the front valve should be opened slowly and then the rear valve should be opened to prevent the instantaneous airflow from damaging the turbine.
Lubrication should be performed according to the notice board. The frequency of refueling depends on the cleanliness of the temperament, usually 2-3 times a year. Due to pressure test and purge
Pipeline or exhaust causing turbine overspeed and turbine running in reverse flow can damage the flowmeter.
When the flowmeter is running, it is not allowed to open the front and rear covers at will, and change the relevant internal parameters, otherwise it will affect the normal operation of the flowmeter.
