The roots blower and water pump in the mechanical roots blower sewage treatment equipment generally operate at the speed of the motor. Shaanxi Sanye Roots Blower adjusts the air volume by changing the opening of the fan outlet valve or the water supply by changing the opening of the adjusting valve on the pump outlet pipeline. The main characteristics of fans and pumps are that the load torque is positively correlated with the square of the rotational speed, and the shaft power is positively correlated with the cubic of the rotational speed. Therefore, if the constant speed operation of the motor is changed to the speed adjusted according to the required flow, a large amount of electric energy can be saved. In the sewage treatment equipment, the main function of Roots blower is to fill the biochemical system with oxygen, so that the biochemical system has sufficient gas.

罗茨鼓风机是一种体积风机，2个三叶轮在外壳和板墙密封的空间内相对转动。因为每个叶轮都采用渐开线，或是外摆线的缠绕线是叶轮加工线，每个叶轮的三个叶子都是一样的，2个叶轮也是一样的，能够降低加工难度。数控机械用以叶轮加工，保证2个叶轮之间的中心间距不变。下面，不管2个叶轮转动到哪里，都能够维持空隙，保证气体泄漏在允许范围内。

Roots blower is a volume fan, with two three-blade wheels rotating relatively in the space sealed by the shell and the plate wall. Because each impeller adopts involute, or the winding line of epicycloid is the impeller processing line, the three leaves of each impeller are the same, and the two impellers are the same, which can reduce the processing difficulty. CNC machine is used for impeller processing to ensure that the center distance between two impellers remains unchanged. Next, no matter where the two impellers rotate, the gap can be maintained to ensure that the gas leakage is within the allowable range.

2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，进风口处在真空状态，气体在大气压力的作用下进到进风口。随后，每个叶轮的两大叶子与墙板和机壳形成一个密封腔。在叶轮转动的过程中，进风口的空气不断被2个叶子形成的密封腔带到出气口。因为出气口里的叶轮互相齿合，2个叶子之间的气体被挤压。

The two impellers rotate in opposite directions. Due to the clearance between impeller and impeller, impeller and casing, impeller and wallboard, the air inlet is in a vacuum state, and the gas enters the air inlet under the action of atmospheric pressure. Then, the two leaves of each impeller form a sealing cavity with the wall panel and the casing. During the rotation of the impeller, the air in the air inlet is constantly brought to the air outlet by the sealing cavity formed by two leaves. Because the impellers in the air outlet mesh with each other, the gas between the two leaves is squeezed.

水塘增氧罗茨风机用途：

Purpose of Roots blower for pond oxygenation:

1、节约资源。罗茨鼓风机具备操作简单、维护方便、性能好、坚固耐用、整机振动幅度小的特性。罗茨鼓风机已被证实具有较好的增氧效果。与传统增氧方式相比，可以达到预期的效果。

1. Save resources. Roots blower has the characteristics of simple operation, convenient maintenance, good performance, durability and small vibration amplitude of the whole machine. Roots blower has been proved to have good oxygenation effect. Compared with the traditional oxygen enrichment method, it can achieve the desired effect.

2、罗茨鼓风机水产养殖改进水产养殖环境。罗茨鼓风机水产养殖在水质底部有广泛的爆气。充足氧化分解物质和亚硝酸钠等有害物质。水里有害有害气体。进而改善水质，造就适宜鱼、虾、蟹的环境。

2. Roots blower aquaculture improves aquaculture environment. Roots blower aquaculture has extensive explosion at the bottom of water quality. Sufficient oxidation decomposition substances, sodium nitrite and other harmful substances. Harmful gas in water. Then improve the water quality and create an environment suitable for fish, shrimp and crab.

3、便于高密度水产养殖。随着静态水下氧气的提升，整个水质里的溶氧就足够了，水质各层水产养殖对象活动能力也有所提高。鱼类的胃口缩短了繁育周期，造就了提升水生物负载的条件。

3. It is convenient for high-density aquaculture. With the improvement of static underwater oxygen, the dissolved oxygen in the whole water quality is enough, and the activity ability of aquaculture objects at all levels of water quality is also improved. The fish's appetite shortens the breeding cycle and creates conditions for improving the aquatic biological load.

4、针对不同的海域，能够配备不同的电源风扇。罗茨鼓风机可实现单池增氧、双池增氧跟多池增氧，主管和旁通管道便于连接和更换。

4. Different power fans can be equipped for different sea areas. Roots blower can realize single-cell, double-cell and multi-cell oxygenation. The main pipe and bypass pipe are easy to connect and replace.

与三叶罗茨鼓风机相比，二叶罗茨鼓风机字面少了一片叶子。与三叶鼓风机相比，二叶鼓风机的体积为两等分和三等分，了导出气旋压力的脉冲。此外，根据叶轮空隙回流到进气腔的排气腔体积，气体扰动提升，脉动压力提升，从而增加罗茨鼓风机的震动。二者有如下差别:

Compared with the three-blade roots blower, the two-blade roots blower literally has one less leaf. Compared with the three-blade blower, the volume of the two-blade blower is divided into two parts and three parts, which leads to the pulse of the cyclone pressure. In addition, according to the volume of the exhaust cavity returned from the impeller gap to the inlet cavity, the gas disturbance increases and the pulsating pressure increases, thus increasing the vibration of the Roots blower. The two have the following differences:

(1)当中心间距与外圆半径相同时，弧形叶三叶罗茨鼓风机的排量大于二叶。渐开叶罗茨鼓风机的排量与转子的数量无关。.

(1) When the center distance is the same as the radius of the outer circle, the displacement of the arc-shaped three-blade roots blower is greater than that of the two-blade blower. The displacement of the involute roots blower is independent of the number of rotors

三叶转子具有较好的机械性能，与二叶相比，能确保叶轮与其叶轮与机壳之间的间隙。.

Three-blade rotor has good mechanical performance. Compared with the second blade, it can ensure the clearance between the impeller and its impeller and casing

(3)因为叶型的特征，三叶脉冲优于二叶脉冲，因此显著的优点是：大大降低振动和噪音，有效降低20声贝以上噪音。.

(3) Because of the characteristics of the blade shape, the trilobal pulse is better than the two-lobal pulse, so the obvious advantages are: greatly reduce the vibration and noise, effectively reduce the noise above 20 dB

与在二叶上使用的轴承相比，在三叶转子上使用的轴承寿命约为15。.

Compared with the bearings used on the second blade, the service life of the bearings used on the third blade rotor is about 15

与二叶风机相比，三叶罗茨风机压力要大得多。.

Compared with the two-blade blower, the pressure of the three-blade Roots blower is much higher

在相同效率下，三叶罗茨风机更。.

At the same efficiency, the three-leaf roots blower is more energy-saving

三叶鼓风机在空隙大小和工作性质相同的情况下，内部泄露流量通常低于二叶鼓风机。.

The internal leakage flow of the three-blade blower is usually lower than that of the two-blade blower under the condition that the gap size and the working nature are the same
