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.

羅茨鼓風機是一種體積風機，2個三葉輪在外殼和板墻密封的空間內(nèi)相對轉(zhuǎn)動。因為每個葉輪都采用漸開線，或是外擺線的纏繞線是葉輪加工線，每個葉輪的三個葉子都是一樣的，2個葉輪也是一樣的，能夠降低加工難度。數(shù)控機械用以葉輪加工，保證2個葉輪之間的中心間距不變。下面，不管2個葉輪轉(zhuǎn)動到哪里，都能夠維持空隙，保證氣體泄漏在允許范圍內(nèi)。

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個葉輪相向轉(zhuǎn)動。由于葉輪與葉輪、葉輪與機殼、葉輪與墻板之間的間隙，進風口處在真空狀態(tài)，氣體在大氣壓力的作用下進到進風口。隨后，每個葉輪的兩大葉子與墻板和機殼形成一個密封腔。在葉輪轉(zhuǎn)動的過程中，進風口的空氣不斷被2個葉子形成的密封腔帶到出氣口。因為出氣口里的葉輪互相齒合，2個葉子之間的氣體被擠壓。

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.

水塘增氧羅茨風機用途：

Purpose of Roots blower for pond oxygenation:

1、節(jié)約資源。羅茨鼓風機具備操作簡單、維護方便、性能好、堅固耐用、整機振動幅度小的特性。羅茨鼓風機已被證實具有較好的增氧效果。與傳統(tǒng)增氧方式相比，可以達到預期的效果。

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、羅茨鼓風機水產(chǎn)養(yǎng)殖改進水產(chǎn)養(yǎng)殖環(huán)境。羅茨鼓風機水產(chǎn)養(yǎng)殖在水質(zhì)底部有廣泛的爆氣。充足氧化分解物質(zhì)和亞硝酸鈉等有害物質(zhì)。水里有害有害氣體。進而改善水質(zhì)，造就適宜魚、蝦、蟹的環(huán)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、便于高密度水產(chǎn)養(yǎng)殖。隨著靜態(tài)水下氧氣的提升，整個水質(zhì)里的溶氧就足夠了，水質(zhì)各層水產(chǎn)養(yǎng)殖對象活動能力也有所提高。魚類的胃口縮短了繁育周期，造就了提升水生物負載的條件。

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、針對不同的海域，能夠配備不同的電源風扇。羅茨鼓風機可實現(xiàn)單池增氧、雙池增氧跟多池增氧，主管和旁通管道便于連接和更換。

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.

與三葉羅茨鼓風機相比，二葉羅茨鼓風機字面少了一片葉子。與三葉鼓風機相比，二葉鼓風機的體積為兩等分和三等分，了導出氣旋壓力的脈沖。此外，根據(jù)葉輪空隙回流到進氣腔的排氣腔體積，氣體擾動提升，脈動壓力提升，從而增加羅茨鼓風機的震動。二者有如下差別:

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)當中心間距與外圓半徑相同時，弧形葉三葉羅茨鼓風機的排量大于二葉。漸開葉羅茨鼓風機的排量與轉(zhuǎn)子的數(shù)量無關(guān)。.

(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

三葉轉(zhuǎn)子具有較好的機械性能，與二葉相比，能確保葉輪與其葉輪與機殼之間的間隙。.

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)因為葉型的特征，三葉脈沖優(yōu)于二葉脈沖，因此顯著的優(yōu)點是：大大降低振動和噪音，有效降低20聲貝以上噪音。.

(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

與在二葉上使用的軸承相比，在三葉轉(zhuǎn)子上使用的軸承壽命約為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

與二葉風機相比，三葉羅茨風機壓力要大得多。.

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

在相同效率下，三葉羅茨風機更。.

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

三葉鼓風機在空隙大小和工作性質(zhì)相同的情況下，內(nèi)部泄露流量通常低于二葉鼓風機。.

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
