时间:2020-07-29浏览量:482

涡街流量计的正确安装是保障仪表正常运行的重要环节,若安装不当,轻则影响仪表的使用精度,重则会影响仪表的使用寿命,甚至会损坏仪表。那么对安装环境有什么要求:

The correct installation of vortex flowmeter is an important link to ensure the normal operation of the instrument. If it is not properly installed, the accuracy of the instrument will be affected, and the service life of the instrument will be affected, and even the instrument will be damaged. What are the requirements for the installation environment

1.尽可能避开强电设备、高频设备、强开关电源设备。仪表的供电电源尽可能与这些设备分离。

1. Avoid strong current equipment, high frequency equipment and strong switching power supply equipment as far as possible. The power supply of the instrument shall be separated from these devices as far as possible.

2.避开高温热源和辐射源的直接影响。若须安装,须有隔热通风措施。

2. Avoid the direct influence of high temperature heat source and radiation source. If installation is required, thermal insulation and ventilation measures shall be taken.

3.避开高湿环境和强腐蚀气体环境。若须安装,须有通风措施。

3. Avoid high humidity environment and strong corrosive gas environment. If installation is required, ventilation measures must be taken.

4.涡街流量仪表应尽量避免安装在振动较强的管道上。若须安装,须在其上下游2D处加设管道紧固装置,并加防振垫,加强抗振效果。

4. Vortex flowmeter should not be installed on the pipe with strong vibration. If it is necessary to install, pipe fastening device and anti vibration pad shall be installed at 2D upstream and downstream to enhance anti vibration effect.

5.仪表应安装在室内,安装在室外应注意防水,特别注意在电气接口处应将电缆线弯成U形,避免水顺着电缆线进入放大器壳内。

5. The instrument should be installed indoors, and waterproof should be paid attention to when it is installed outdoors. Special attention should be paid to bending the cable into U shape at the electrical interface to avoid water flowing into the amplifier shell along the cable.

6.仪表安装点周围应该留有较充裕的空间,以便安装接线和定期维护。

6. Sufficient space should be reserved around the instrument installation point for installation, wiring and regular maintenance.

涡街流量计安装的环境条件如上所述,在之后的安装之前要注意这些哦。

The environmental conditions of vortex flowmeter installation are as mentioned above. Pay attention to these before installation.
