英國GRIMM格林進口羅茨風機概述： 

          進口羅茨風機是英國格林在長年制造經(jīng)驗的基礎(chǔ)上采用的新技術(shù)開發(fā)的產(chǎn)品。
          進口羅茨風機是一種雙葉輪同步壓縮機械，每個三葉型轉(zhuǎn)子用兩個軸承支承，利用一對同步齒輪，使兩個轉(zhuǎn)子的相對位置始終保持不變。屬容積式鼓風機，具有強制輸氣特征。三葉羅茨風機作為回轉(zhuǎn)式機械，具有比較穩(wěn)定的工作特征，三葉羅茨風機轉(zhuǎn)子與轉(zhuǎn)子、轉(zhuǎn)子與泵體、轉(zhuǎn)子與側(cè)蓋之間有微小間隙，因而工作腔內(nèi)沒有摩擦，無接觸磨損部分；三葉羅茨風機經(jīng)濟耐用，無需潤滑，使用壽命長，動力平衡性好。
          本風機通過葉輪采用新的型線，使風機的泄露低，效率高，噪音低。各種機型在干燥狀態(tài)下使用的排風壓力可達到98KPa。引進先進噴涂技術(shù)，對葉輪表面進行噴涂、防腐、耐磨。

英國GRIMM格林進口羅茨風機特點： 

1、螺旋形狀20°以上的固定螺旋方式。機殼的進排風屏蔽線切入螺旋，以轉(zhuǎn)子頂端光面線構(gòu)成的三角形進排風口，通過轉(zhuǎn)子的旋轉(zhuǎn)而循序打開。本風機發(fā)進排風口，不像舊式羅茨螺旋風機那樣在瞬間打開或關(guān)閉，所以運轉(zhuǎn)聲音極小，幾乎沒有排風脈動。
2、因為轉(zhuǎn)子是三葉直線形，所以它不像螺旋式轉(zhuǎn)子那樣，因軸向微小變位而使轉(zhuǎn)子相互接觸。因此，只在剖面上保證轉(zhuǎn)子間的間隙即可，不需要像轉(zhuǎn)子螺旋式那樣再加上軸向變位，以致間隙過大。這種風機的效率比相同尺寸的轉(zhuǎn)子螺旋式風機好得多。
3、因轉(zhuǎn)子采用特殊外形，便于保持轉(zhuǎn)子間的相互間隙，使效率進一步提高。
4、因使用精密數(shù)控機床批量市場轉(zhuǎn)子，并對精度管理采取了完善的措施，所以，各臺風機之間完全沒有性能誤差。另外，轉(zhuǎn)子在制造過程中已成平衡狀態(tài)。所以轉(zhuǎn)子不會像過去那樣殘留微小的不平衡，本機幾乎完全沒有振動。
5、采用驅(qū)動齒輪，不僅使壽命得到延長，而且實現(xiàn)了低噪音化。該齒輪采用特殊Cr-Mo鋼經(jīng)適當淬火處理，嚴格按照Jlsl級齒輪精度精研削制造。因而將來自齒輪對產(chǎn)品的不良干擾完全排除。
6、輸出的空氣清潔，不含任何油質(zhì)灰塵。機殼內(nèi)部不須油類潤滑，且采用了避免軸承、齒輪油類混入機殼內(nèi)部的結(jié)構(gòu)設(shè)計。
7、隨著公司品質(zhì)管理、生產(chǎn)車間管理體制的確立，實現(xiàn)了部件相互交流、低生產(chǎn)成本，短期交貨的目標。
8、采用了小型設(shè)計，安裝面積小。

英國GRIMM格林進口羅茨風機工作原理： 
         進口羅茨風機為容積式風機，輸送的風量與轉(zhuǎn)數(shù)成比例，三葉型羅茨風機葉輪每轉(zhuǎn)動一次由兩個葉輪進行三次吸、排氣，與二葉型相比，氣體脈動變少、負荷變化小、機械強度高、噪音低、振動也小。
           在兩根至相平行的軸上設(shè)有兩個三葉型葉輪，葉輪與橢圓形機箱內(nèi)孔面及兩葉輪三者之間始終保持微小的間隙，由于葉輪互為反方向勻速旋轉(zhuǎn)，使箱體與葉輪所包圍著的一定量的氣體由一側(cè)輸送到排出的一側(cè)。
           各只葉輪始終由同步齒輪保持正確的相位，不會出現(xiàn)互相碰觸現(xiàn)象，因而可以高速化，不需要內(nèi)部潤滑，而且，結(jié)構(gòu)簡單、運轉(zhuǎn)平衡、性能穩(wěn)定、適應多種用途，已運用于廣泛的領(lǐng)域。

UK GRIMM Imported roots blower summary:

        The imported roots blower is the development of new technology in the manufacture of Britain's Green based on the experience of using the product.

          The imported roots blower is a double impeller synchronous compression machine, two bearings with each trilobe rotor, using a pair of synchronous gears, the relative position of two rotor remains constant. It is a positive displacement blower with forced gas transmission characteristics. Roots blower as rotary machinery, has the characteristics of relatively stable, there is a small gap between Roots blower rotor and rotor, the rotor and the pump body, rotor and side cover, the cavity without friction, no wear parts; roots blower, economic durable, no lubrication, long service life. Balance and good.

          The fan adopts a new type of thread through the impeller, so that the fan leakage is low, the efficiency is high, and the noise is low. The exhaust pressure of various models in dry state can reach 98KPa. The introduction of advanced spraying technology, the impeller surface spraying, anti-corrosion, wear-resistant.

UK GRIMM Imported roots blower characteristic: 

1. Spiral shape more than 20 degrees fixed spiral. The inlet and outlet wind shielding wires of the shell are inserted into the spiral, and the triangular inlet and the air outlets which are formed by the smooth line of the rotor end are sequentially opened through the rotation of the rotor. This fan is sent into the air outlet, not like the old roots spiral fan, so it opens or closes in an instant, so the operation is very small, and there is hardly any exhaust pulsation.

2. Because the rotor is a three leaf straight line, so it is not like the spiral rotor, because of the axial micro change and make the rotor contact each other. Therefore, the gap between the rotors can be ensured only on the section, and the axial clearance is not necessary as the rotor spiral, so that the clearance is too large. The efficiency of this fan is much better than that of a screw rotor fan of the same size.

3. Because the rotor adopts a special shape, easy to maintain the gap between the rotor, so that the efficiency is further improved.

4. Due to the use of precision CNC machine tools, mass market rotor, and the accuracy of management has taken perfect measures, so there is no performance error between the typhoon machines. In addition, the rotor is in equilibrium during manufacture. So the rotor doesn't remain as tiny and unbalanced as it used to be, and the machine is almost completely free of vibration.

5. The use of the most advanced driving gear, not only to prolong the life, but also to achieve a low noise. The gear is made of special Cr-Mo steel, which has been properly quenched and manufactured precisely according to the precision of Jlsl gear. Thus, the bad interference from the gear to the product is completely eliminated.

6. The output of air clean, without any oil dust. The inner part of the casing is not lubricated with oil, and the structure design of avoiding the bearing and the gear oil mixed with the inner part of the casing is adopted.

7. With the company quality management, production workshop management system established, to achieve the components of mutual exchange, low production costs, short-term delivery target.

8. The use of small design, installation area is small.

UK GRIMM Imported roots blower working principle: 

        The import volume of blower fan, air transport and revolution in proportion, clover Roots blower impeller rotating each time by two to three times the impeller suction and discharge, compared with the two leaf type, gas pulsation is reduced and the load change is small, high mechanical strength, low noise, small vibration.

          In two parallel to the shaft is provided with two trefoil impeller, between the impeller and the oval box hole surface and the two impeller three always maintain a small gap, mutually opposite direction as the impeller rotates, the side of the box body and the gas amount of impeller surrounded by the side of delivery to discharge.

          The impeller is always by synchronous gear to maintain the correct phase, does not appear to touch each other, thus can speed, without internal lubrication, and has the advantages of simple structure, stable operation, stable performance, adapt to a variety of uses, has been used widely.

UK GRIMM Imported roots blower performance table description: 

The performance represents the fan type, caliber, speed, exhaust pressure, air volume and the required power.

1. The performance table shows the air volume standard air inlet air volume. The so-called standard state is that the temperature is 20 degrees centigrade, the absolute pressure is 1.0332kgf/cm2{101.3kpa}, the relative humidity is 65%.

2. The baseline temperature (temperature 0 degrees, absolute pressure 1.0332kgf/cm2{101.3kpa}) of the air flow, generally expressed as Nm3/min. Under the same inlet air pressure, the down flow can be converted into the air quantity in the standard state:

Qs=QN * 1.0332

Qs: standard status air volume (m3/min)

QN: reference status air volume (m3/min)

3. The exhaust air volume can be converted into the standard state air volume:

               1.0332+Pd          273+ts
Qs=Qd×——————×—————
                   1.0332             273+td

Qd: exhaust air volume (m3/min)

Pd: exhaust pressure: kgf/cm2

TS: inlet air temperature (DEG C)

TD: exhaust temperature (DEG C)

4. The exhaust pressure of air volume is calculated according to the above results, and then the fan type, caliber, speed and power are obtained according to the performance table.

5. The performance table shows different motor output power in different colors. Please use the motor of the corresponding power.

6, some fans of the model, its selection is repeated. From the angle of economy, small fans should be selected, and large fans should be selected from the angle of noise.
