低温废水回收设备安装时的注意事项有哪些呢?为了更好的在后期工作中使用,这个问题是要及时了解到的,下面小编就来为您讲讲吧。
What are the precautions for the installation of low-temperature wastewater recovery equipment? In order to better use it in later work, this problem should be learned in time. Let's talk about it.
1、正压负压问题:的方法为负压方式,即风机安装在前端,处理机内部压力相对于大气为负压。负压方式有多种好处,例如,气流稳定,无漏气,效果相对于正压有所提高等。正压只有在特殊情况下才会使用,例如安装特殊性,场地限制,等。
1. Positive pressure and negative pressure: the recommended method is negative pressure, that is, the fan is installed at the front end, and the internal pressure of the processor is negative pressure relative to the atmosphere. Negative pressure mode has many advantages, such as stable air flow, no air leakage, and improved effect compared with positive pressure. Positive pressure can only be used under special circumstances, such as installation particularity, site restrictions, etc.
2、软连接与风机须通过软连接,主要考虑振动问题。
2. Soft connection and fan must be connected through soft connection, mainly considering vibration.
3、风机基础与处理机基础处理机基础只要保证抗风性能即可。无特殊要求。风机基础则须符合安装规范。特别要注意共振问题。
3. Fan foundation and processor foundation The processor foundation only needs to ensure the wind resistance performance. No special requirements. The fan foundation shall comply with the installation specifications. Pay special attention to resonance.
4、风阻问题由于设计主要采用低速管道,所以不必过分考虑风阻。但是每个拐弯要增大50帕的压力,因此管道应尽量平直安装。
4. The problem of wind resistance is that the low-speed pipeline is mainly used in the design, so it is unnecessary to consider the wind resistance too much. However, the pressure of 50Pa shall be increased at each turn, so the pipe shall be installed as straight as possible.
5、过滤问题过滤器的效果对于工程很重要,须予以重视。特别是过滤器的风阻,应在现场实测。过大的风阻会引起通风量不足。测量方法采用多点计算法。详见其他技术资料。
5. Filtration problem The effect of the filter is very important to the project and should be paid attention to. In particular, the air resistance of the filter shall be measured on site. Excessive wind resistance will cause insufficient ventilation. The measurement method is multipoint calculation method. See other technical data for details.
6、流场现场很难实时确定流场。由于大截面动压甚低,不要试图测量流速。使用香烟烟雾测量流场也是错误的,因为香烟烟雾是热流体,而且由于分子力的作用,会快速扩散。可以实际应用的方法是通过抽气效果推断流场,虽然粗糙,但是目前可以的方法。例如可以散发示踪气体等。
6. It is difficult to determine the flow field in real time. Do not attempt to measure the velocity because the dynamic pressure of the large section is very low. It is also wrong to use cigarette smoke to measure the flow field, because cigarette smoke is a hot fluid and will spread rapidly due to molecular force. The method that can be used in practice is to infer the flow field through the air extraction effect. Although it is rough, it can be used at present. For example, tracer gas can be emitted.
7、密封问题相对于其他工程,由于压力甚低,密封问题不需要特别个关注。
7. Compared with other projects, the sealing problem does not require special attention due to very low pressure.
8、天圆地方与变截面规整的设计应避免现场制作天圆地方与变截面连接管道,但是当现场条件有变化时,可以使用天圆地方与变截面进行校正,另外,软连接也可以提供误差校正,虽然很小。
8. The design of the round sky and the variable cross-section should avoid the on-site fabrication of the round sky and the variable cross-section connecting pipes. However, when the site conditions change, the round sky and the variable cross-section can be used for correction. In addition, the soft connection can also provide error correction, although very small.
室外安装:防阳光直射与防雨,虽然很简单,但是非常重要。缺乏该项设施有可能导致我方设备在性能与寿命方面达不到设计要求。请务必注意。更多相关内容就来我们网站
