Select the pneumatic conveying Roots blower with appropriate air volume and pressure

氣力輸送風(fēng)機(jī)的風(fēng)量和風(fēng)壓是風(fēng)機(jī)選型過(guò)程中兩個(gè)重要的基本參數(shù)。氣力輸送風(fēng)機(jī)的壓力取決于氣力輸送系統(tǒng)的壓力，也要適當(dāng)考慮系統(tǒng)內(nèi)阻力及可能的管道損失，氣力輸送風(fēng)機(jī)的壓力還要保證氣力輸送系統(tǒng)出現(xiàn)小故障時(shí)也能操作。

Air volume and air pressure of pneumatic conveying fan are two important basic parameters in the process of fan selection. The pressure of the pneumatic conveying fan depends on the pressure of the pneumatic conveying system, and the resistance in the system and the possible pipeline loss should also be properly considered. The pressure of the pneumatic conveying fan should also ensure that the pneumatic conveying system can operate safely in case of a small fault.

由于四季氣候條件的變化以及工藝操作本身的波動(dòng)，使得所需的氣力輸送風(fēng)機(jī)風(fēng)量和風(fēng)壓也需相應(yīng)變動(dòng)，因此在選擇氣力輸送羅茨鼓風(fēng)機(jī)時(shí)，應(yīng)盡量使風(fēng)機(jī)的運(yùn)行工況包含在風(fēng)機(jī)特性曲線的有效使用區(qū)范圍內(nèi)。

Due to the change of climatic conditions in four seasons and the fluctuation of process operation itself, the required air volume and air pressure of the pneumatic conveying fan also need to change accordingly. Therefore, when selecting the pneumatic conveying roots blower, the operating conditions of the fan should be included in the effective use area of the fan characteristic curve as far as possible.

羅茨鼓風(fēng)機(jī)的效率

Efficiency of roots blower

氣力輸送風(fēng)機(jī)作為整個(gè)氣力輸送系統(tǒng)的動(dòng)力來(lái)源，其效率的高低直接關(guān)系到整個(gè)輸送設(shè)備的輸送效率。風(fēng)機(jī)的效率決定著氣力輸送風(fēng)機(jī)正常運(yùn)行的經(jīng)濟(jì)性，因此應(yīng)盡可能選擇額定效率高的風(fēng)機(jī)，以使氣力輸送風(fēng)機(jī)全年都能盡可能長(zhǎng)時(shí)間的經(jīng)濟(jì)運(yùn)行。

As the power source of the whole pneumatic conveying system, the efficiency of pneumatic conveying fan is directly related to the conveying efficiency of the whole conveying equipment. The efficiency of the fan determines the economy of the normal operation of the pneumatic conveying fan. Therefore, the fan with high rated efficiency should be selected as far as possible so that the pneumatic conveying fan can operate economically for as long as possible throughout the year.

盡可能選擇滿足高壓操作能力的氣力輸送羅茨鼓風(fēng)機(jī)

Try to select the pneumatic conveying roots blower that meets the high pressure operation capability

氣力輸送過(guò)程中，有時(shí)工況要求高壓操作進(jìn)行輸送或者清理管道灰塵。高壓操作要求氣力輸送羅茨鼓風(fēng)機(jī)要有滿足高壓操作的壓力，保證在高壓操作下能向管道供應(yīng)足夠的風(fēng)量。

In the process of pneumatic conveying, sometimes the working conditions require high-pressure operation for conveying or cleaning the dust in the pipeline. The high pressure operation requires that the pneumatic conveying roots blower should have the pressure to meet the high pressure operation and ensure that it can supply enough air volume to the pipeline under the high pressure operation.

我們?cè)谶x擇氣力輸送羅茨鼓風(fēng)機(jī)時(shí)，要充分考慮現(xiàn)場(chǎng)工況環(huán)境所需的性能要求以及氣力輸送系統(tǒng)的整體設(shè)計(jì)，選擇性能滿足要求，性價(jià)比高的氣力輸送風(fēng)機(jī)不僅可保障物料氣力輸送的正常進(jìn)行，還能保證經(jīng)濟(jì)性，

When selecting the pneumatic conveying roots blower, we should fully consider the performance requirements required by the site working conditions and the overall design of the pneumatic conveying system, and select the pneumatic conveying fan with high performance and price ratio to meet the requirements, which can not only ensure the normal operation of the pneumatic conveying of materials, but also ensure the economy,
