Turbine flowmeter fault rapid processing introduction

Turbine flowmeter is a speed meter with high precision, low moving parts, high pressure resistance, wide measuring range, low pressure loss and convenient maintenance. As long as the correct installation and commissioning are in normal use, there will be no measurement error. of. Let's share with you, where to find the cause when the turbine flowmeter fails, and deal with the fault as soon as possible to ensure normal operation.

1. No display when the fluid is in normal activity, the total number of counters does not increase.

1. Verify that the power cord, fuse, power selection switch, and signal cable are open or poorly connected.

2. Check the external printing plate of the display, contact parts, etc. for poor contact

3. Inspection detection coil

4. Check the external fault of the sensor. The above 1-3 tests confirm that the problem is normal or has been removed, but there is still a problem, and the fault is explained outside the sensor flow path. It can be tested whether the impeller can touch the inner wall of the sensor and whether there is any foreign matter stuck. , shaft and bearing have no debris stuck or broken sight

Second, the treatment plan

1. Use ohmmeter to check for problems

2. Printing board fault test can be exchanged "alternate version" method, replaced with faulty board and then carefully examined

3. Do a good job to mark the position of the detection coil on the sensor body, unscrew the detection head, and use the iron piece to move rapidly under the detection head. If the number of counters does not increase, check the coil for disconnection and solder joint de-soldering.

4. Remove foreign matter, and clean or change the damaged parts. After recovery, blow the air or hand the impeller. There should be no friction. After changing the bearings and other parts, re-calibrate and obtain the new meter factor.
