Advantages and disadvantages of turbine flowmeter and points for attention
Advantages and disadvantages of turbine flowmeter and points for attention the rotation of shaft can be sensed mechanically or by detecting the movement of blades.Head fitness exercises are generally tested with a magnetic method, with each head or piece of copper inserted creating a single pulse.Turbine flowmeter controllers are generally located on the outside of the flow flow to prevent the raw materials from structural constraints if the wet controller is applied.When the fluid moves rapidly, it creates a large number of single pulses.The emitters resolve differential signals to clarify fluid fluidity.Intelligent transmitter and sensor system software can be used to check the total flow in both the forward and reverse flow directions.
Advantages and disadvantages of turbine flowmeter and points for attention
Advantages and disadvantages of turbine flowmeter:
Cost is moderate.It is suitable for cleaning high viscosity fluid with moderate speed and smooth speed.The reduction is good because it can load very low total traffic.If put in the liquid that clean, have wettability especially below the condition, they are reliable.AGA and API are permitted for trade work handover.They do lead to some reduction in work stress, which will be an element of, for example, mobility.You can't count on steam.
Turbine flowmeters are used to accurately measure the flow of water through pipelines for liquids, vapors, and vapors, such as carbonoxidizing substances, compounds, water, cryogenic liquids, gases, and industrial gases.High precision turbine flowmeter can be used for the handover of nitrous oxide and gas trade.The turbine flowmeter generally includes the function of a flow computer for positive operating pressure, temperature, and fluid characteristics to achieve the precision required for operation.
In the case of no rundown fluid, be careful to apply turbine flowmeter, because if the flowmeter is damaged too soon, the flowmeter will become more and more inaccurate and ineffective.Some turbine flowmeters have lubricating grease parts for non-wetting fluids.In addition, turbine flowmeters designed for a particular major purpose (such as gas service projects) generally operate within a limited temperature range (such as 60 ° C), so that actual operation at higher temperatures will destroy the flowmeter.
This type of flowmeter can be used for environmental hygiene, relative cleanliness and corrosive liquids up to approximately 24 feet in size.Smaller turbine flowmeters can be installed immediately in the pipeline, but larger turbine flowmeter specifications and net weights will have to be installed with a lot of concrete base and support points.Pay proper attention to the fluidity of corrosive liquid, pay proper attention to the construction raw materials of all liquid receiving components, such as valve body, motor rotor, rolling bearing and spare parts.
Turbine flowmeters can be found in water, petroleum and chemical industries.Water application includes distribution system software within and between water areas.Oil use involves the transfer of trade work involving nitrogen-oxide compounds.Other applications can be found in food and beverage and its chemical industry
Where does manufacturing apply
This is used in oil and gas, water and sewage, gas utilities, chemical plants, electrical engineering, food and beverage, aerospace, pharmaceuticals, metal materials and mining and wood pulp and paper industries, in descending order.
Common problems in turbine flowmeter application:
Because the friction resistance of the motor rotor/rolling bearing reduces the motor rotor, the accuracy of the turbine flowmeter is lower at a low total flow rate.Ensure that the actual operation of the flowmeter is approximately 5% of the total flow.The turbine flowmeter cannot operate at high speed due to premature damage and/or destruction of the rolling bearings.Care should be taken in accurate measurement of unwetted fluid as damage to the rolling bearing may render the flowmeter increasingly inaccurate and ineffective.In some applications, the rolling bearing replacement will have to be carried out on time and increase the maintenance cost.In general, the use of dirty fluid should be prevented to reduce the probability of flowmeter damage and rolling bearing damage.In a word, the fitness component of turbine flowmeter will decline with time and application.
Sudden flows from the vapor into the liquid flow should be prevented, as they can cause ground stress to the mechanical equipment on the flowmeter, reducing accuracy and/or destroying the flowmeter.This condition generally occurs under the filling line and plug flow standards.Two-phase flow standards will also cause inaccurate turbine flowmeter measurements.
Porcelain city Shanghai instruments co., LTD. Is China's first tiny elliptical gear manufacturers, by MrStone (Siemens) senior engineers involved research and development, with independent intellectual property rights, completely using Siemens CNC processing center production and processing equipment, to ensure the minimum flow rate of 0.1 ml/min, which is rare in the world, the precision is over 90%.
