英国GRIMM格林进口罗茨风机概述: 

          进口罗茨风机是英国格林在长年制造经验的基础上采用的新技术开发的产品。
          进口罗茨风机是一种双叶轮同步压缩机械,每个三叶型转子用两个轴承支承,利用一对同步齿轮,使两个转子的相对位置始终保持不变。属容积式鼓风机,具有强制输气特征。三叶罗茨风机作为回转式机械,具有比较稳定的工作特征,三叶罗茨风机转子与转子、转子与泵体、转子与侧盖之间有微小间隙,因而工作腔内没有摩擦,无接触磨损部分;三叶罗茨风机经济耐用,无需润滑,使用寿命长,动力平衡性好。
          本风机通过叶轮采用新的型线,使风机的泄露低,效率高,噪音低。各种机型在干燥状态下使用的排风压力可达到98KPa。引进先进喷涂技术,对叶轮表面进行喷涂、防腐、耐磨。

英国GRIMM格林进口罗茨风机特点: 

 

 

1、螺旋形状20°以上的固定螺旋方式。机壳的进排风屏蔽线切入螺旋,以转子顶端光面线构成的三角形进排风口,通过转子的旋转而循序打开。本风机发进排风口,不像旧式罗茨螺旋风机那样在瞬间打开或关闭,所以运转声音极小,几乎没有排风脉动。
2、因为转子是三叶直线形,所以它不像螺旋式转子那样,因轴向微小变位而使转子相互接触。因此,只在剖面上保证转子间的间隙即可,不需要像转子螺旋式那样再加上轴向变位,以致间隙过大。这种风机的效率比相同尺寸的转子螺旋式风机好得多。
3、因转子采用特殊外形,便于保持转子间的相互间隙,使效率进一步提高。
4、因使用精密数控机床批量市场转子,并对精度管理采取了完善的措施,所以,各台风机之间完全没有性能误差。另外,转子在制造过程中已成平衡状态。所以转子不会像过去那样残留微小的不平衡,本机几乎完全没有振动。
5、采用zui高级驱动齿轮,不仅使寿命得到延长,而且实现了低噪音化。该齿轮采用特殊Cr-Mo钢经适当淬火处理,严格按照Jlsl级齿轮精度精研削制造。因而将来自齿轮对产品的不良干扰完全排除。
6、输出的空气清洁,不含任何油质灰尘。机壳内部不须油类润滑,且采用了避免轴承、齿轮油类混入机壳内部的结构设计。
7、随着公司品质管理、生产车间管理体制的确立,实现了部件相互交流、低生产成本,短期交货的目标。
8、采用了小型设计,安装面积小。

英国GRIMM格林进口罗茨风机工作原理: 
          进口罗茨风机为容积式风机,输送的风量与转数成比例,三叶型罗茨风机叶轮每转动一次由两个叶轮进行三次吸、排气,与二叶型相比,气体脉动变少、负荷变化小、机械强度高、噪音低、振动也小。
          在两根至相平行的轴上设有两个三叶型叶轮,叶轮与椭圆形机箱内孔面及两叶轮三者之间始终保持微小的间隙,由于叶轮互为反方向匀速旋转,使箱体与叶轮所包围着的一定量的气体由一侧输送到排出的一侧。
          各只叶轮始终由同步齿轮保持正确的相位,不会出现互相碰触现象,因而可以高速化,不需要内部润滑,而且,结构简单、运转平衡、性能稳定、适应多种用途,已运用于广泛的领域。

英国GRIMM格林进口罗茨风机性能表说明: 
性能表示了风机型号、口径、转速、排风压力、风量和所需要动力的关系。

2、基准状态(温度0℃,绝对压力1.0332kgf/cm2{101.3kpa})的风量,一般以Nm3/min表示。在进风压力相同的情况下,可用下式换算成标准状态的风量:
Qs=QN×1.0332
Qs:标准状态风量(m3/min)
QN:基准状态风量(m3/min)
3、可用下式把排风状态风量换算成标准状态风量: 
               1.0332+Pd          273+ts

5、性能表以不同的颜色示出了不同的电机输出功率,请用户使用相应功率的电机。
6、有些风机的型号其选定范围是重复的。从经济的角度,应选用小型风机,从噪音的角度,应选用大型风机。

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.
