Turbine flowmeter has the obvious advantages of compact structure, clear and intuitive reading, high reliability, no external power interference, lightning strike resistance, low cost, etc. It is widely used in petroleum, chemical, metallurgy, papermaking and other industries to measure liquid volume instantaneous flowmeter. And total volume. Seeing some people on the Internet asking, when the turbine flow meter is used, it is found that the accuracy is reduced. What is the reason? 1, the media generally have some impurities, the bearing, the shaft should wear, so that the gap between the two increases, the dynamic balance of the moving parts is destroyed, the speed is reduced, or dirt into the gap, so that the resistance to increase the movement , Speed ​​drops. All of these reasons cause the display value of the instrument to decrease, causing a negative error, which is detrimental to the fluid supplier. 2. The fibrous or viscous impurities in the fluid are attached to the rotating part of the flowmeter, which increases the rotational resistance, causing the indicator value of the instrument to decrease, causing negative errors, and adverse to the fluid supplier. 3. Changes in fluid temperature and pressure may cause air in the pipeline to escape, or the pressure in the pipeline is lower than the saturation vapor pressure of the fluid, making part of the liquid into steam, or it may be caused by the negative pressure of the medium. The gas is sucked into the pipeline. These gases flow along with the measured fluid, causing the indicator value of the instrument to increase, causing a positive error, which is detrimental to the demand of the fluid. 4, the working environment is rather harsh, for example, electromagnetic field interference, dust, high temperature, vibration, humidity, etc., may cause malfunction or failure of the turbine flow sensor, directly caused by the turbine flowmeter error, the error is positive or negative The value may not be obvious or it may completely fail. For the above phenomenon, when it is more serious, problems can be found in the comparison of the working status of the process, and it is easy to take corresponding measures. However, in the early stages of the problem, problems could not be discovered without special measures. Turbine flowmeter maintenance should pay attention to the following points: 1. When used, the measured media should be kept clean, free from impurities such as fibers and particles. 2. When the turbine flow sensor is used, the sensor should be filled with medium slowly, and then the outlet valve should be opened (the valve should be installed at the back end of the flowmeter). It is forbidden that the sensor is exposed to high-speed fluid when it is in no medium state. 3, the maintenance cycle of turbine flow sensor is generally six months. During maintenance cleaning, please be careful not to damage the parts in the measuring chamber, especially the impeller. Please pay attention to the positional relationship between the guide and the impeller when assembling. 4. When the turbine flow sensor is not in use, the internal medium should be cleaned, and after drying, a protective sleeve should be added at both ends of the sensor to prevent dust from entering and then stored in a dry place. 5, equipped with a filter should be regularly cleaned, when not in use should clean the internal media, with the same sensor, add the dust jacket, placed in a dry place. 6. Before the sensor is installed, use the mouth to blow or dial the impeller to make it rotate quickly to see if there is any display, and then install the sensor when it is displayed. If there is no display, check the relevant parts and troubleshoot.
