进口罗茨风机‖GERMANY BACH/上海代理
一、产品概述：
罗茨风机属容积式风机，叶轮端面、风机前后端盖。原理是利用两个叶形转子在气缸内作相对运动来压缩和输送气体的回转压缩机。这种鼓风机结构简单，制造方便，广泛应用于水产养殖增氧、污水处理曝气、水泥输送，更适用于低压力场合的气体输送和加压系统，也可用作真空泵等。
二、产品组成：
罗茨风机由：机壳、墙板、叶轮、油箱、消声器五大部分组成。
机壳：主要起到支撑（墙板、叶轮、消声器）和固定的作用。
墙板：主要用来连接机壳与叶轮，并支撑叶轮的旋转，以及起到端面密封的效果。
叶轮：是罗茨风机的旋转部分，分两叶和三叶，但由于三叶的比两叶的出气脉动更小、噪声更小、运转更平稳等很多优点，已逐渐代替两叶罗茨风机。
油箱：主要用于存放用来润滑齿轮及轴承的润滑油。
消声器：用来减小罗茨风机的进、出时由于气流脉动产生的噪音。
三、工作原理：
罗茨风机是容积式风机的一种，有两个三叶叶轮在由机壳和墙板密封的空间中相对转动，由于每个叶轮都是采用渐开线，或是外摆线的包络线，每个叶轮的三个叶片是完全相同的，同时两个叶轮也是完全相同的，这样就大大降低了加工难度。叶轮在加工时采用数控设备，保证了两个叶轮在中心距不变情况下，不管两个叶轮旋转到什么位置，都能保持一定的***间隙，从而保证气体的***在允许范围内。
两个叶轮相向转动，由于叶轮与叶轮、叶轮与机壳、叶轮与墙板之间的间隙***，从而使进气口形成了真空状态，空气在大气压的作用下进入进气腔，然后，每个叶轮的其中两个叶片与墙板、机壳构成了一个密封腔，进气腔的空气在叶轮转动的过程中，被两个叶片所形成密封腔不断地带到排气腔，又因为排气腔内的叶轮是相互啮合的，从而把两个叶片之间的空气挤压出来，这样连续不停的运转，空气就源源不断地从进气口输送到出气口，这就是罗茨风机的整个工作过程。
First, product overview:
Roots blower is a positive displacement blower, impeller end, fan cover. The principle is to use two leaf rotor to compress and transport the rotary compressor in the cylinder. This type of blower is simple in structure and convenient in manufacture. It is widely used in aquaculture, aeration, sewage treatment aeration and cement delivery. It is more suitable for gas transportation and pressure systems in low pressure situati***, and also used as vacuum pumps.
Two. Product composition:
The blower c***ists of five parts: impeller, casing, wall panels, fuel tank, muffler.
Case: main support (wall panel, impeller, muffler) and fixed function.
Wallboard: mainly used to connect the shell and impeller, and to support the rotation of the impeller, and to play the effect of end seal.
Impeller: it is the rotated part of the roots blower, which is divided into two le***es and three le***es, but it has gradually replaced the two blade roots fan because the three le***es h***e a lot of advantages, such as less air pulsation, ***aller noise and more ***ooth operation than the two leaf.
Fuel tank: mainly used for storing lubricants for lubricating gears and bearings.
Muffler: to reduce blower inlet and outlet due to airflow pulsation noise.
Three. The principle of work:
The roots blower is a kind of volume type fan. There are two three blade impellers rotating relatively in the space sealed by the shell and wallboard. As each impeller uses the involute, or the envelope of the outer cycloid, the three blades of each impeller are exactly the same, and the two impellers are exactly the same, so it is greatly reduced. Lower the difficulty of processing. When the impeller is machined, the numerical control equipment is used to ensure that the two impellers can keep a certain minimum gap, regardless of the position of the two impellers, to ensure the leakage of the gas within the allowable range.
The two impeller turns, because the clearance between the impeller and the impeller, the impeller and the casing, the impeller and the wall plate is very ***all, so that the air inlet forms a vacuum state, and the air enters the intake chamber under the action of atmospheric pressure. Then, two of the blades of each impeller are sealed with the wall and the machine shell, and the air intake c***ity is formed. Air in the process of impeller rotation, the seal c***ity formed by two blades is c***tantly brought to the exhaust c***ity, and because the impeller in the exhaust c***ity is intermeshing, the air between the two blades is squeezed out so that the air is continuously running from the inlet to the outlet. The whole working process of the blower.
