低溫廢水回收設(shè)備安裝時(shí)的注意事項(xiàng)有哪些呢?為了更好的在后期工作中使用,這個(gè)問(wèn)題是要及時(shí)了解到的,下面小編就來(lái)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(fù)壓?jiǎn)栴}:的方法為負(fù)壓方式,即風(fēng)機(jī)安裝在前端,處理機(jī)內(nèi)部壓力相對(duì)于大氣為負(fù)壓。負(fù)壓方式有多種好處,例如,氣流穩(wěn)定,無(wú)漏氣,效果相對(duì)于正壓有所提高等。正壓只有在特殊情況下才會(huì)使用,例如安裝特殊性,場(chǎng)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(jī)須通過(guò)軟連接,主要考慮振動(dòng)問(wèn)題。
2. Soft connection and fan must be connected through soft connection, mainly considering vibration.
3、風(fēng)機(jī)基礎(chǔ)與處理機(jī)基礎(chǔ)處理機(jī)基礎(chǔ)只要保證抗風(fēng)性能即可。無(wú)特殊要求。風(fēng)機(jī)基礎(chǔ)則須符合安裝規(guī)范。特別要注意共振問(wèn)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(wèn)題由于設(shè)計(jì)主要采用低速管道,所以不必過(guò)分考慮風(fēng)阻。但是每個(gè)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(guò)濾問(wèn)題過(guò)濾器的效果對(duì)于工程很重要,須予以重視。特別是過(guò)濾器的風(fēng)阻,應(yīng)在現(xiàn)場(chǎng)實(shí)測(cè)。過(guò)大的風(fēng)阻會(huì)引起通風(fēng)量不足。測(cè)量方法采用多點(diǎn)計(jì)算法。詳見(jiàn)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(chǎng)現(xiàn)場(chǎng)很難實(shí)時(shí)確定流場(chǎng)。由于大截面動(dòng)壓甚低,不要試圖測(cè)量流速。使用香煙煙霧測(cè)量流場(chǎng)也是錯(cuò)誤的,因?yàn)橄銦煙熿F是熱流體,而且由于分子力的作用,會(huì)快速擴(kuò)散??梢詫?shí)際應(yīng)用的方法是通過(guò)抽氣效果推斷流場(chǎng),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(wèn)題相對(duì)于其他工程,由于壓力甚低,密封問(wèn)題不需要特別個(gè)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(jì)應(yīng)避免現(xiàn)場(chǎng)制作天圓地方與變截面連接管道,但是當(dāng)現(xiàn)場(chǎng)條件有變化時(shí),可以使用天圓地方與變截面進(jìn)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:防陽(yáng)光直射與防雨,雖然很簡(jiǎn)單,但是非常重要。缺乏該項(xiàng)設(shè)施有可能導(dǎo)致我方設(shè)備在性能與壽命方面達(dá)不到設(shè)計(jì)要求。請(qǐng)務(wù)必注意。更多相關(guān)內(nèi)容就來(lái)我們網(wǎng)站
