使用過(guò)程中,螺桿鼓風(fēng)機(jī)會(huì)有出口溫度(溫升)過(guò)高的問(wèn)題,那如果真空的發(fā)生這樣的問(wèn)題的時(shí)候,又該如何去處理呢?

In the process of using, the outlet temperature (temperature rise) of screw blower is too high. How to deal with the problem of vacuum?

影響螺桿鼓風(fēng)機(jī)出口溫度的因素包括:鼓風(fēng)機(jī)的容積效率、工作壓力、內(nèi)泄漏情況以及入口空氣溫度等。這些因素中,大部分和鼓風(fēng)機(jī)的設(shè)計(jì)與工藝水平有關(guān)系,它們?cè)诠娘L(fēng)機(jī)選型結(jié)束就已定型,難以改變,因此簡(jiǎn)單的就是在降低工作壓力、入口溫度上進(jìn)行考慮。

The factors that affect the outlet temperature of screw blower include volume efficiency, working pressure, internal leakage and inlet air temperature. Most of these factors are related to the design and process level of the blower. They have been finalized at the end of the blower selection and are difficult to change. Therefore, the simple consideration is to reduce the working pressure and inlet temperature.

鼓風(fēng)機(jī)入口溫度和工作壓力的變化會(huì)直接影響到出口溫度的變化。因此,螺桿鼓風(fēng)機(jī)出口溫度如果太高,就可以首先考慮能否降低工作壓力以及入口的空氣溫度:

The change of inlet temperature and working pressure of blower will directly affect the change of outlet temperature. Therefore, if the outlet temperature of screw blower is too high, we can first consider whether we can reduce the working pressure and the inlet air temperature

1、減少壓損。

1. Reduce pressure loss.

我們可以看到壓力如果上升1米水柱,螺桿鼓風(fēng)機(jī)的出口溫度會(huì)有所上升,因此,減少不必要的壓損,可以有用降低鼓風(fēng)機(jī)的出口溫度,來(lái)自管路設(shè)計(jì)產(chǎn)生的壓損、過(guò)濾器、曝氣頭等設(shè)備產(chǎn)生的壓損等等。

We can see that if the pressure rises by 1 m water column, the outlet temperature of the screw blower will rise. Therefore, reducing unnecessary pressure loss can effectively reduce the outlet temperature of the blower, pressure loss from pipeline design, pressure loss from filters, aeration head and other equipment, etc.

2、降低入口溫度。

2. Lower the inlet temperature.

螺桿鼓風(fēng)機(jī)大多安裝在室外,因此需要保證良好的通風(fēng),同時(shí)避免接近其他熱源,以降低環(huán)境溫度與鼓風(fēng)機(jī)入口溫度;如果風(fēng)機(jī)是裝在室內(nèi)的,有條件的可以裝空調(diào),不僅可以降低設(shè)備入口空氣溫度,進(jìn)而降低出口排氣溫度,同時(shí)也可以延長(zhǎng)電機(jī)等設(shè)備的壽命。

Screw blowers are mostly installed outdoors, so it is necessary to ensure good ventilation and avoid approaching other heat sources to reduce the ambient temperature and blower inlet temperature; If the fan is installed indoors, air conditioning can be installed if conditions permit. It can not only reduce the air temperature at the inlet of the equipment, but also reduce the exhaust temperature at the outlet. At the same time, it can extend the life of the motor and other equipment.

3、裝有隔音罩的,必要時(shí)打開(kāi)隔音罩,如在夏天時(shí)。

3. If equipped with acoustic enclosure, open the acoustic enclosure if necessary, such as in summer.

很多的隔音罩起不到明顯的隔音作用,倒是可能因封閉的環(huán)境導(dǎo)致內(nèi)部溫度增高,從而使鼓風(fēng)機(jī)入口溫度偏高,進(jìn)而影響出口排氣溫度。所以在必要的場(chǎng)合,可以打開(kāi)或放棄隔音罩。

A lot of noise enclosures do not play a significant role in sound insulation, but the internal temperature may increase due to the closed environment, which will make the inlet temperature of the blower higher, and then affect the outlet exhaust temperature. So in the necessary occasions, you can open or give up the acoustic enclosure.

鼓風(fēng)機(jī)出口溫度太高在很多領(lǐng)域會(huì)影響下一步生產(chǎn)作業(yè),如在曝氣領(lǐng)域會(huì)影響氧溶解以及微生物的生存環(huán)境等,因此在發(fā)現(xiàn)出口排氣溫度過(guò)高時(shí)應(yīng)該及時(shí)處理。

If the outlet temperature of the blower is too high, it will affect the next production operation in many fields, such as in the aeration field, it will affect the oxygen dissolution and the living environment of microorganisms, so it should be dealt with in time when the outlet exhaust temperature is too high.
