低溫廢水回收設(shè)備安裝時的注意事項

作者：admin來源：http://m.dijiushangdian.cn/時間：2022-09-20

低溫廢水回收設(shè)備安裝時的注意事項有哪些呢？為了更好的在后期工作中使用，這個問題是要及時了解到的，下面小編就來為您講講吧。

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、正壓負壓問題：推薦的方法為負壓方式，即風(fēng)機安裝在前端，處理機內(nèi)部壓力相對于大氣為負壓。負壓方式有多種好處，例如，氣流穩(wěn)定，無漏氣，效果相對于正壓有所提高等。正壓只有在特殊情況下才會使用，例如安裝特殊性，場地限制，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、軟連接與風(fēng)機須通過軟連接，主要考慮振動問題。

2. Soft connection and fan must be connected through soft connection, mainly considering vibration.

3、風(fēng)機基礎(chǔ)與處理機基礎(chǔ)處理機基礎(chǔ)只要保證抗風(fēng)性能即可。無特殊要求。風(fēng)機基礎(chǔ)則須符合安裝規(guī)范。特別要注意共振問題。

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、風(fēng)阻問題由于設(shè)計主要采用低速管道，所以不必過分考慮風(fēng)阻。但是每個拐彎要增大５０帕的壓力，因此管道應(yīng)盡量平直安裝。

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、過濾問題過濾器的效果對于工程很重要，須予以重視。特別是過濾器的風(fēng)阻，應(yīng)在現(xiàn)場實測。過大的風(fēng)阻會引起通風(fēng)量不足。測量方法采用多點計算法。詳見其他技術(shù)資料。

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、流場現(xiàn)場很難實時確定流場。由于大截面動壓甚低，不要試圖測量流速。使用香煙煙霧測量流場也是錯誤的，因為香煙煙霧是熱流體，而且由于分子力的作用，會快速擴散。可以實際應(yīng)用的方法是通過抽氣效果推斷流場，雖然粗糙，但是目前可以的方法。例如可以散發(fā)示蹤氣體等。

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、密封問題相對于其他工程，由于壓力甚低，密封問題不需要特別個關(guān)注。

7. Compared with other projects, the sealing problem does not require special attention due to very low pressure.

8、天圓地方與變截面規(guī)整的設(shè)計應(yīng)避免現(xiàn)場制作天圓地方與變截面連接管道，但是當現(xiàn)場條件有變化時，可以使用天圓地方與變截面進行校正，另外，軟連接也可以提供誤差校正，雖然很小。

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.

室外安裝重點：防陽光直射與防雨，雖然很簡單，但是非常重要。缺乏該項設(shè)施有可能導(dǎo)致我方設(shè)備在性能與壽命方面達不到設(shè)計要求。請務(wù)必注意。更多相關(guān)內(nèi)容就來我們網(wǎng)站m.dijiushangdian.cn咨詢吧！

Key points for outdoor installation: protection against direct sunlight and rain. Although it is simple, it is very important. The lack of such facilities may cause our equipment to fail to meet the design requirements in terms of performance and service life. Please pay attention.
