The importance of installing Verabar flowmeters
2011-10-29 16:40:44

    威力巴流量计 应注意以下几点要求: We should pay attention to the following requirements when installing Verabar flowmeters :

要想延长 威力巴流量计 的使用寿命;必须做到以下 3点: 1. In order to extend the service life of Verabar flowmeters , the following 3 points must be achieved :

有没有 弯曲变形; a. Regularly inspect the Willabar body for bending and deformation;

b. Periodic inspection of Verabar valves and connecting flanges;

有没有 泄漏、堵塞。 c. Regularly inspect the Verabar joints for leaks and blockages.

在测量中,管道如果 有振动 ;我们必须采取措施,比如 2. In the measurement, if there is vibration in the pipeline ; we must take measures such as   流量计 的两边加支撑。 Add support on both sides of the flowmeter .

我们在使用每一支 威力巴探头时,需要对它做一些处理: 3. When we use each Verabar probe, we need to do something with it:

⑴ Differential pressure analysis;

⑵ Stress analysis;

⑶ structural analysis;

According to the above process, the differential pressure calculated to determine the range of the differential pressure transmitter .

,会遇到这种情况;如 Fourth, we will encounter this situation when measuring gas and steam ; such as   温度的影响 ,那么我们就要考虑是不是 进行补偿。 The measurement accuracy will be affected by pressure changes and temperature , so we must consider whether to compensate.

直管段不够长时 ;我们需要在 弯管后 2 倍管道 处安装一个 威力巴流量计。 5. In special cases, when the straight pipe section of the pipeline is not long enough ; we need to install a Verabar flowmeter at the pipe 2 times after the bend .

6. Measure liquid . 威力巴流量计 安装的范围在 160 ° 管道下方 In general, Verabar flowmeters are installed below the 160 ° pipe . 时, 威力巴流量计 安装的范围在 160 ° 管道 方;测量蒸汽 时,在 垂直管道 的情况下, 威力巴流量计 安装的范围是 360 °的任何位置。 When installing gas , Verabar flowmeters can be installed above a 160 ° pipe ; when measuring steam , Verabar flowmeters can be installed at any position of 360 ° in a vertical pipe .

安装 旁通管道 的目的有两个: 流量计 流量计的维护。 7. The purpose of installing the bypass pipeline is twofold: cleaning of the flowmeter ; maintenance of the flowmeter.

杂质中的小颗粒 进入到 探头高压平衡区 ,破坏取压孔时,就会引起 引压管泄漏 8. When the small particles in the impurities enter the high pressure balance area of the probe and damage the pressure taking hole, it will cause the impulse tube to leak . 小颗粒 也会 进入取压管 ;引起同样的情况。 If it is not working, small particles will also enter the pressure taking pipe ; causing the same situation. 探头 的定期 清洗。 So we need to clean the probes regularly .
