2.1

风机进排气机壳及回流器通过参数优化充分与叶轮匹配，流线型设计损失更小。

The blower inlet and outlet casing, as well as the reflux device, are fully matched with the impeller through parameter optimization, resulting in a streamlined design with less loss.

2.2

部分风机叶轮采用高效三元流叶轮设计，并经CFD流体动力学分析，效率更高。

Some blower impellers are designed with high-efficiency ternary flow impellers and have been analyzed by CFD fluid dynamics, resulting in higher efficiency.

2.3

每级叶轮进口设置导流圆弧，引导气流平稳进入叶轮，能有效地使气流阻力降到最低，降低叶轮入口压力损失，最大限度地将机械能转变为流体动能。

Each stage of the impeller inlet is equipped with a guide arc to smoothly guide the airflow into the impeller, effectively reducing the airflow resistance and minimizing the pressure loss at the impeller inlet, maximizing the conversion of mechanical energy into fluid kinetic energy.

2.4

机翼型回流器叶片设计技术，损失小，静压能转换更高。

Wing shaped reflux blade design technology, with low losses and higher static pressure energy conversion.

2.5

应用流动分析技术优化鼓风机性能，鼓风机多变效率在80%以上。

Using flow analysis technology to optimize the performance of the blower, the variable efficiency of the blower is above 80%.

2.6

同一鼓风机满足50 Hz和60 Hz两种转速，风机调节范围宽，性能更好。

The same blower can meet two speeds of 50 Hz and 60 Hz, with a wide adjustment range and better performance.

2.7

转子经严格动平衡后，风机振动小，可靠性高，整体噪音低。

After strict dynamic balancing of the rotor, the blower has low vibration, high reliability, and overall low noise.

2.8

轴承座采用两端外布置，便于拆装和更换轴承，轴承座留有检测装置安装孔。

The bearing seat is arranged at both ends for easy disassembly and replacement of bearings, and there are installation holes for detection devices in the bearing seat.

2.9

除轴承部位外风机内部的转动件与风机壳体间均无任何摩擦，每级叶轮于隔板间均采用非接触式迷宫密封，以减少气体内泄漏。

Except for the bearing parts, there is no friction between the rotating parts inside the blower and the blower casing. Non-contact labyrinth seals are used between each stage of the impeller and the partition to reduce gas leakage.

2.10

风机可根据产品参数选用滚动轴承或滑动轴承，保证风机能够在长期稳定运行的基础上，有更高的性价比和更为友好的安装环境。

The blower can be equipped with rolling bearings or sliding bearings according to product parameters, ensuring that the blower can operate stably for a long time with higher cost-effectiveness and a more friendly installation environment.

2.11

联轴器一般采用精度较高的膜片联轴器进行连接，其工作安全系数大于1.5。该联轴器形式能保证客户更为方便的安装和维护。

Couplings are generally connected using high-precision diaphragm couplings, with a working safety factor greater than 1.5. This coupling form can ensure more convenient installation and maintenance for customers.

2.12

鼓风机主要零部件全部在数控加工中心上生产加工，对需方所订购的数台具有相同特性的风机，供方提供的部件及备用件具有完全互换性。

The main components of the blower are all produced and processed on a CNC machining center, and the parts and spare parts provided by the supplier are fully interchangeable for several blowers with the same characteristics ordered by the demand side.

2.13

制造的每台鼓风机都是严格按照JB/T3165-1999 《离心和轴流式鼓风机压缩机热力性能试验》标准的要求来测试验收，合格后方可出厂。

Each blower manufactured is strictly tested and accepted in accordance with the requirements of JB/T3165-1999 "Thermal Performance Test for Centrifugal and Axial Blowers and Compressors" standard, and can only be shipped after passing the test.
