山東螺桿式風(fēng)機(jī)發(fā)展較晚,是一種新型的回轉(zhuǎn)式風(fēng)機(jī),分為單螺桿與雙螺桿式,市場(chǎng)上常見的為雙螺桿式。雙螺桿結(jié)構(gòu)由瑞典人里斯曼發(fā)明,先用于壓縮機(jī)領(lǐng)域,到20世紀(jì)末,雙螺桿結(jié)構(gòu)在鼓風(fēng)機(jī)領(lǐng)域才開始獲得較快發(fā)展,并在諸多應(yīng)用領(lǐng)域展現(xiàn)里良好的易用性,如、穩(wěn)定等。憑借良好的性能,在較多領(lǐng)域開始逐漸替代傳統(tǒng)風(fēng)機(jī)。

Screw fan is a new type of rotary fan, which can be divided into single screw type and double screw type. The common type in the market is twin-screw type. The twin-screw structure was invented by Riesman of Sweden and was first used in the field of compressor. By the end of the 20th century, the twin-screw structure began to obtain rapid development in the field of blower, and showed good ease of use in many application fields, such as energy saving, stability, etc. With good performance, it has gradually replaced the traditional fan in many fields.

一、螺桿風(fēng)機(jī)的結(jié)構(gòu)

1、 Structure of screw fan

以錦工雙螺桿鼓風(fēng)機(jī)為例,螺桿風(fēng)機(jī)一般主要由外罩、主機(jī)、電機(jī)、空氣過濾器、消音器、油泵油箱以及油慮等部分構(gòu)成。錦工雙螺桿鼓風(fēng)機(jī)可根據(jù)客戶要求進(jìn)行定制,比如去掉外罩、改為無油系統(tǒng)等。

Taking Jingong twin-screw blower as an example, screw fan is generally composed of cover, main engine, motor, air filter, muffler, oil pump tank and oil filter. Jingong twin-screw blower can be customized according to customer requirements, such as removing the cover, changing to oil-free system, etc.

螺桿主機(jī)作為螺桿風(fēng)機(jī)的核心部件,其結(jié)構(gòu)直接決定了風(fēng)機(jī)性能的優(yōu)劣。螺桿主機(jī)主要由機(jī)殼、螺桿轉(zhuǎn)子、齒輪箱、軸承、軸封等主要部件構(gòu)成。

As the core component of screw fan, the structure of screw host directly determines the performance of the fan. Screw host is mainly composed of casing, screw rotor, gearbox, bearing, shaft seal and other main components.

二、螺桿風(fēng)機(jī)的運(yùn)行原理

2、 Operation principle of screw fan

螺桿式風(fēng)機(jī)的運(yùn)行原理是兩根平行的陰陽(yáng)轉(zhuǎn)子在“∞”形氣缸中相互嚙合形成工作容積,通過同步齒輪,轉(zhuǎn)子作反向高速轉(zhuǎn)動(dòng),隨著轉(zhuǎn)子轉(zhuǎn)動(dòng)工作容積的大小發(fā)生周期性的變化,在氣體輸送過程中同時(shí)實(shí)現(xiàn)氣體的壓縮。螺桿式風(fēng)機(jī)的工作循環(huán)可分為吸氣、壓縮和排氣三個(gè)過程。其循環(huán)過程如下所示:

The operation principle of screw fan is that two parallel male and female rotors mesh with each other in the "∞" cylinder to form the working volume. Through synchronous gears, the rotor rotates in reverse high speed. With the rotor rotation, the working volume changes periodically, and the gas compression is realized in the process of gas transmission. The working cycle of screw fan can be divided into three processes: suction, compression and exhaust. The cycle process is as follows:

1、吸氣過程

1. Inspiratory process

氣體經(jīng)吸氣口進(jìn)入轉(zhuǎn)子齒間容積,隨著轉(zhuǎn)子的轉(zhuǎn)動(dòng),齒間容積不斷擴(kuò)大,當(dāng)齒間容積達(dá)到時(shí),齒間容積與吸氣口斷開,吸氣過程結(jié)束。

The gas enters into the inter tooth volume of the rotor through the suction port. With the rotation of the rotor, the volume between teeth expands continuously. When the volume between teeth reaches the maximum, the volume between teeth is disconnected from the suction port, and the suction process is finished.

3、排氣過程

3. Exhaust process

齒間容積與排氣口連通后,排氣過程開始。轉(zhuǎn)子轉(zhuǎn)動(dòng)過程中,齒間容積不斷減小,將壓縮后的氣體送排氣管。此過程一直延續(xù)到該容積達(dá)

After the volume between teeth is connected with the exhaust port, the exhaust process begins. During the rotation of the rotor, the volume between the teeth decreases continuously, and the compressed gas is sent to the exhaust pipe. This process continues until the volume reaches

三、螺桿式風(fēng)機(jī)的特點(diǎn)

3、 Characteristics of screw fan

螺桿式風(fēng)機(jī)在腔體內(nèi)氣體輸送的過程中實(shí)現(xiàn)了內(nèi)壓縮,因此螺桿擁有羅茨大部分的優(yōu)點(diǎn)之外,同時(shí)比羅茨具備更高的效率,且氣體的輸送壓縮的過程是連續(xù)漸進(jìn)的,氣流脈動(dòng)更低,排氣噪音、溫度控制等均要優(yōu)于羅茨等傳統(tǒng)風(fēng)機(jī)。

Screw fan realizes internal compression in the process of gas transportation in the cavity, so screw has most of the advantages of roots, and has higher efficiency than roots. Moreover, the process of gas transportation and compression is continuous and gradual, with lower flow pulsation, better exhaust noise and temperature control than roots and other traditional fans.

作為近年來新興發(fā)展的回轉(zhuǎn)式鼓風(fēng)機(jī)種類,螺桿風(fēng)機(jī)因其結(jié)構(gòu)簡(jiǎn)單,穩(wěn)定、低噪音等優(yōu)勢(shì),開始普遍出現(xiàn)在曝氣、氣水反沖、氧化脫硫、流化/均化工藝、氣力輸送等應(yīng)用中,并將會(huì)成為各個(gè)行業(yè)風(fēng)機(jī)選擇亮點(diǎn)。

As a new type of rotary blower in recent years, screw fan has been widely used in aeration, gas water backwash, oxidation desulfurization, fluidization / homogenization process, pneumatic conveying and other applications due to its simple structure, stability, energy saving and low noise, and will become the highlight of fan selection in various industries.
