| V cone flowmeter routine maintenance matters |
| 2011-5-20 18:13:22 |
In daily life, the use of V-cone flowmeters requires us to do some simple maintenance. The following precautions please pay attention to:
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 main maintenance steps and related fault inspection sequence of the V-cone flowmeter are introduced in detail below.
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，则要注意防止取压管路中时间长了含有水气，当含有水气的时候，变送器的信号输出会是一个波动的现象。 1. When measuring V-cone flowmeters containing a small amount of particles or 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.
2. The second is the maintenance of the differential pressure transmitter that is matched with the V-cone flowmeter . Such maintenance is mainly reflected in the measurement of steam, because the on-site temperature is too high, which may cause the transmitter to zero point shift and affect the measurement Precision. Therefore, zero calibration of the differential pressure transmitter on site is required.
3. 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 . V锥流量计传感器本身是不会出现什么问题，剩下的就是现场管道布置问题和二次仪表的故障检查了。 In fact, anyone who has done production knows that if there are no problems with the field parameters, there will be no problems with the V-cone flowmeter sensor itself. The rest is the on-site pipeline layout problems and the secondary instrument failure inspection. You can refer to the previous article or call the company's technical department: 0517-86901324.
4. 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%. Indoors without corrosive gases.
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.
