In daily life, the use of V-cone flowmeters requires us to do some simple maintenance. The following precautions please pay attention to:
由于现场配套设备相对于比较多点，所以正常对V锥流量计本身进行一定的维护才能保证现场正常运行和测量精度。 Due to the relatively large number of supporting equipment on the V-cone flowmeter, normal maintenance of the V-cone flowmeter itself can ensure the normal operation and measurement accuracy of the field. The following is a detailed introduction to the V-cone flowmeter.
On-site main maintenance steps and related fault inspection sequence.
1. The storage of V-cone flowmeter spare parts should meet the following requirements: during transportation, avoid severe vibration, bumps and damage, and store it in a ventilated room with a temperature of -10 to + 40 ° C and a relative humidity not exceeding 85%. No corrosive gas
在测量含少量颗粒的时候或者测量混相流介质的时候，必须定期的对取压管路进行清洗，以保证测量管路的流通；而对于压缩空气的测量，则要注意 2. When the V-cone flowmeter measures a small amount of particles or when measuring mixed-phase flow media, the pressure-taking pipeline must be cleaned regularly to ensure the circulation of the measurement pipeline; for the measurement of compressed air, attention must be paid to
Prevent the pressure taking pipeline from containing water vapor for a long time. When water vapor is contained, the signal output of the transmitter will be a fluctuating phenomenon.
3. The second is the maintenance of the differential pressure transmitter that is matched with the V-cone flowmeter. This kind of maintenance is mainly reflected in the measurement of steam, because the on-site temperature is too high, which may cause the on-site transmitter to migrate and affect the measurement. fine
degree. Therefore, zero calibration of the differential pressure transmitter on site is required.
4. If there is a significant difference between the displayed value of the differential pressure gauge and the measured value, a comprehensive inspection and adjustment shall be carried out, and a measurement verification shall be performed again if necessary. In fact, anyone who has done production knows that if there are no problems with the field parameters, the V cone
The flow meter sensor itself will not cause any problems, and the rest is the problem of on-site pipeline layout and secondary instrument failure inspection.
的现场维护可能还不是太详细，但对现场的维护人员应该是有一定参考作用的，有什么需要完善的地方，还请大家不吝赐教。 The on-site maintenance of the V-cone flowmeter explained above may not be too detailed, but it should be a reference for the on-site maintenance personnel. If there is anything that needs to be improved, please enlighten me.
