高壓風(fēng)機與羅茨風(fēng)機的不同之處

發(fā)布時間:2022-05-10 來源:http://lzdbgs.com.cn/

高壓風(fēng)機分成旋渦風(fēng)機和羅茨風(fēng)機,就是指工作壓力較高的風(fēng)機。
High pressure fan is divided into vortex fan and Roots fan, which refers to the fan with high working pressure.
旋渦風(fēng)機又叫漩渦氣泵,其基本原理是:當(dāng)葉輪旋轉(zhuǎn)時,因為離心力的功能,風(fēng)向標氣體往前向外運動,進而產(chǎn)生一系列螺旋狀的運動。葉輪刀片間的空氣呈螺旋狀旋轉(zhuǎn)并將泵體以外的氣體擠進(由吸氣口吸進)側(cè)槽,當(dāng)它進到側(cè)通道之后,氣體被壓縮,隨后又恢復(fù)到葉輪刀片間再度加快旋轉(zhuǎn)。當(dāng)空氣順著一條螺旋形軌道越過葉輪和側(cè)槽時,每個葉輪片提升了壓縮和加快的程度,伴隨著旋轉(zhuǎn)的開展,氣體的動能提升,促使沿側(cè)通道經(jīng)過的氣體壓力更進一步提升。當(dāng)空氣抵達側(cè)槽與排放法蘭的連接點(側(cè)通道在出口處變窄),氣體即被擠出葉片并經(jīng)過出口消聲器排出泵體。
Vortex fan is also called vortex air pump. Its basic principle is that when the impeller rotates, due to the function of centrifugal force, the wind vane gas moves forward and outward, resulting in a series of spiral movements. The air between the impeller blades rotates in a spiral shape and squeezes the gas outside the pump body into the side groove (sucked in by the suction port). When it enters the side channel, the gas is compressed, and then returns to the impeller blades to accelerate the rotation again. When the air crosses the impeller and side slot along a spiral track, each impeller blade improves the degree of compression and acceleration. With the development of rotation, the kinetic energy of the gas increases, which further increases the gas pressure passing along the side channel. When the air reaches the connection point between the side slot and the discharge flange (the side channel narrows at the outlet), the gas is squeezed out of the blade and discharged from the pump body through the outlet muffler.
羅茨風(fēng)機為容積式風(fēng)機,運輸?shù)娘L(fēng)量與轉(zhuǎn)速成比例,三葉型葉輪每旋轉(zhuǎn)一次由2個葉輪開展3次吸、排氣,與二葉型相比,氣體脈動減少,負荷變化小,機械強度高,噪聲低,振動也小。在2根平相行的軸上設(shè)有2個三葉型葉輪,輪與橢圓形機箱內(nèi)孔面及各葉輪三者間始終保持微小的間隙,因為葉輪相互之間反方向勻速旋轉(zhuǎn),使箱體和葉輪所包圍著的一定的氣體由吸進的一側(cè)輸送到排出的一側(cè)。各支葉輪始終由同步齒輪維持正確的相位,并不會發(fā)生互相碰觸現(xiàn)象,因此能夠 高速化,不用內(nèi)部潤滑,并且構(gòu)造簡易,運轉(zhuǎn)穩(wěn)定,性能穩(wěn)定,適用各種用途,已應(yīng)用于廣泛的領(lǐng)域。旋渦風(fēng)機和羅茨風(fēng)機有很大的區(qū)別,結(jié)構(gòu)形式和基本原理及工作特性都不同。
Roots fan is a positive displacement fan. The air volume transported is proportional to the speed. Each time the three blade impeller rotates, two impellers carry out suction and exhaust for three times. Compared with the two blade impeller, the gas pulsation is reduced, the load change is small, the mechanical strength is high, the noise is low and the vibration is small. Two three blade impellers are arranged on the two parallel shafts, and a small gap is always maintained between the wheel and the inner hole surface of the oval box and each impeller, because the impellers rotate at a uniform speed in the opposite direction, so that a certain amount of gas surrounded by the box and the impeller is transmitted from the suction side to the discharge side. The correct phase of each impeller is always maintained by the synchronous gear without touching each other. Therefore, it can be high-speed without internal lubrication, simple structure, stable operation and stable performance. It is suitable for various purposes and has been used in a wide range of fields. There are great differences between vortex fan and Roots fan, with different structural forms, basic principles and working characteristics.
