廠家建議選擇離心風(fēng)機的五個合理方(fāng)式

發布時間:2018-12-16人(rén)氣:109

選擇一款好的離心風機,最重要的前提要先了解你要選購的(de)這台(tái)離心風機的(de)工作環境,在排塵、防爆、防腐等不同的環境中作業肯定是需(xū)要(yào)選擇不同的風機的。此外,合理的選擇離心風機除了滿足流量與風壓的要求以外,還要(yào)考慮風機高效運行的需求,這是選擇風機的重要因素。風機性能是風機合理選型的依據,風機性能的表示方法不同,風機選型的方法也(yě)不同。建議你依據(jù)以下幾個(gè)方式來選擇風機

Choose a good centrifugal fan, the most important premise is to understand the centrifugal fan you want to buy the working environment, in the dust, explosion-proof, anti-corrosion and other different environments must be selected in different fans. In addition, reasonable selection of centrifugal fans in addition to meeting the flow and wind pressure requirements, but also consider the need for efficient operation of the fan, which is an important factor in selecting the fan. Fan performance is the basis for the rational selection of fan, fan performance is expressed in different ways, fan selection methods are also different. It is recommended that you choose fans according to the following ways.

1、依據風機的性(xìng)能曲線選擇風機。這(zhè)是一種最基(jī)本也比(bǐ)較簡單的方法。

1, choose the fan according to the performance curve of the fan. This is a basic and simple method.

2、利用(yòng)風機性能表來選擇風機,這種方法與利用水泵性(xìng)能表選擇水泵相同(tóng),雖然簡單方便,但(dàn)是不能準(zhǔn)確地確定風機裝置工況。

2. Use the fan performance table to select the fan. This method is the same as using the pump performance table to select the pump. Although it is simple and convenient, it can not accurately determine the working condition of the fan device.

3、利用風機的性能選擇(zé)曲線選擇風(fēng)機這是風機選擇中(zhōng)最常用的一種方法。選擇(zé)曲線是把同一相似係列,不同葉輪外徑 的每一台風(fēng)機的全壓,功率,轉速與流量的關係,在對數坐(zuò)標圖上所(suǒ)標繪的(de)一係列線族

3, choose the fan using the performance curve of the fan, which is the most commonly used method of fan selection. Selection curves are a series of lines drawn on logarithmic coordinate maps that relate the total pressure, power, rotational speed and flow rate of each fan of the same series and different impeller diameters.

4、利用風機無量綱性能曲線選擇風機風機無量綱性能曲線是表示各種型(xíng)式,不(bú)同機號的係列風機的無量綱性能參數。為了縮小選擇的範圍,先選定風機的(de)轉速。計(jì)算風(fēng)機的比轉數,再由(yóu)值查找離心風機的無量綱曲(qǔ)線,找出與計算(suàn)比轉數最為接近並且本身效率又較高的風機作為(wéi)選定的風機型式。

4. Using dimensionless performance curve of fan to select dimensionless performance curve of fan is dimensionless performance parameter of series fans of different types and sizes. In order to narrow the scope of the selection, the speed of the fan is selected first. The specific speed of the fan is calculated, and then the dimensionless curve of the centrifugal fan is searched by the value. The fan with the closest specific speed and higher efficiency is found as the selected fan type.

5、根據所選風機的(de)性能曲線和管路性能曲線,考慮係統(tǒng)管路布置方式和(hé)風機(jī)運行方式,圖解(jiě)裝(zhuāng)置運(yùn)行(háng)工況和風機運行(háng)參數。如果需要運行工(gōng)況調節的,應根據采用的調節方法圖(tú)解調節工況,確定相應的調節工況參數。對於可采(cǎi)用多種方法調節時,應進行不同方法的(de)經濟性分析,以確定最合理的調節方法。

5. According to the performance curve and pipeline performance curve of the selected fan, the system pipeline layout and fan operation mode are considered, and the operating conditions of the device and fan operation parameters are illustrated. If it is necessary to adjust the operating conditions, the corresponding operating parameters should be determined by demodulating the throttle conditions according to the adopted adjusting method diagram. When adjusting by various methods, the economic analysis of different methods should be carried out to determine the most reasonable adjustment method.
