Turbine Flowmeter Failure Analysis and Treatment
Turbine flow meter is a kind of speed meter and a new generation of intelligent VNLW turbine flow meter produced by Shunda Flowmeter manufacturer. It features high precision, small moving parts, high pressure resistance, wide measuring field, low pressure loss, convenient maintenance, etc. As long as the correct installation and commissioning are ensured, there will be no measurement error in normal use. The following technical Xiaobian of Heshunda will share with you the reasons for finding faults when turbine flowmeters fail, and handle the faults as soon as possible to ensure normal operation. First, there is no display when the fluid is active, and the total counter word does not increase. 1. Inspect the power cord, fuse, power selector switch, and signal line for open or bad contacts 2. Check whether the external printing plate of the display device and contacts are in poor contact 3. Inspection coil 4. Check the outside of the sensor for faults. The above 1-3 tests confirm that they are normal or have been removed. However, there are still problems. The problem is explained outside the sensor flow path. It can be checked whether the impeller can touch the inner wall of the sensor and there is no foreign matter stuck. , Shafts and bearings with or without debris stuck or broken Second, the treatment plan 1. Use ohmmeter to troubleshoot 2. Printed board defects can be exchanged "backup version" method, replace the fault board and conduct detailed inspection 3. Do a good job of detecting the position of the coil on the sensor body and mark it, unscrew the test head, quickly move with the iron under the test head, if the word count does not increase, you should check whether the coil breaks and solder joints off 4. Remove foreign matter, and clean or replace damaged parts. After recovery, air blow or hand toggle the impeller, there should be no friction sound. After replacing bearings and other parts, it should be recalibrated to obtain a new meter factor. As a professional R&D flowmeter manufacturing enterprise, Heshun Flowmeter manufacturers have been persisting in the production concept of “quality and brand†and “brands and development†for the past few years. They persist in making unremitting efforts to tackle difficult problems and constantly research and develop new technologies and products. Our customers provide products with reliable quality and conform to the demand. At the same time, we have established a long-term cooperation relationship with many production companies. All colleagues of Heshunda look forward to working with you to set sail. We are a manufacturer of FRP Pressure Tank and FRP Membrane Housing, and provide FRP water tanks and FRP RO Membrane housing water treatment accessories.
