一、使用范围不同

1、 Different scope of use

回转式风机可用于医院、实验室、人口聚集区生活的污水处理;印刷行业的真空送纸;电镀槽、工业废水的搅拌曝气;塑焊、吹风的气源供应;燃烧器的喷雾、玻璃工业及其它等。

The rotary fan can be used for domestic sewage treatment in hospitals, laboratories and population gathering areas; Vacuum paper feeding in printing industry; Stirring and aeration of electroplating tank and industrial wastewater; Air supply for plastic welding and blowing; Burner spray, glass industry and others.

罗茨鼓风机可用于建材、电力、冶炼、化肥、矿山、轻纺、食品、造纸、石化、污水处理以及环保产业等诸多领域,还可用于输送煤气、氢气、乙炔、二氧化碳等易燃、易爆及腐蚀性气体。

Roots blower can be used in many fields such as building materials, electric power, smelting, chemical fertilizer, mining, light textile, food, papermaking, petrochemical, sewage treatment and environmental protection industries. It can also be used to transport flammable, explosive and corrosive gases such as gas, hydrogen, acetylene and carbon dioxide.

二、噪音大小不同

2、 Different noise levels

回转式风机更大的优点就是低噪音,静音型或者小型的回转风机噪音只有45分贝左右,稍大型的或非静音型的噪音在80分贝左右,因此特别适用于对噪音控制严格的工程中。罗茨鼓风机根据风机型号不同,风机噪音也不一样,通常噪音在75分贝至110分贝之间,因此两者相比较,罗茨鼓风机的噪音高,不适用于要求低噪音的工程中。

The biggest advantage of rotary fan is low noise. The noise of silent or small rotary fan is only about 45 dB, and the noise of slightly large or non silent fan is about 80 dB. Therefore, it is especially suitable for projects with strict noise control. According to different fan models, the noise of Roots blower is also different. Generally, the noise is between 75db and 110dB. Therefore, compared with the two, roots blower has high noise and is not suitable for projects requiring low noise.

三、风压、风量不同

3、 Different air pressure and air volume

回转式风机风压范围在0.1-0.5kgf/cm2,属于中压风机,而罗茨鼓风机的风压范围是在0.1-0.8kgf/cm2之间,属于高压风机。因回转式鼓风机的风压或风量达不到要求,大型工程使用罗茨风机比较好。罗茨鼓风机的风压和风量可以任意调动,更适合大型工程使用,但是功率开大,罗茨鼓风机的噪音也会随之增大,为达到降低噪音的目的,建议使用隔音罩降低噪音,但是会增加成本。

The wind pressure range of rotary fan is 0.1-0.5kgf/cm2, belonging to medium pressure fan, while the wind pressure range of Roots blower is 0.1-0.8kgf/cm2, belonging to high pressure fan. Because the air pressure or air volume of the rotary blower can not meet the requirements, roots blower is better for large-scale projects. The air pressure and air volume of Roots blower can be adjusted arbitrarily, which is more suitable for large-scale projects. However, when the power is turned on, the noise of Roots blower will increase. In order to reduce the noise, it is recommended to use sound insulation cover to reduce the noise, but the cost will be increased.

四、环保性不同

4、 Different environmental protection

罗茨鼓风机的内腔不需要润滑油,只需对风机齿轮添加齿轮油,而回转式风机在运转中为减少摩擦和噪声,会利用压力差自动将润滑油送到滴油嘴,滴入汽缸内,因此罗茨鼓风机输送的气体是干净的,无污染;而回转式鼓风机将润滑油滴入汽缸内时,会有微量的油进入水体,而且排气口会有油雾出现,因此食品行业选用风机时,还是罗茨鼓风机比较好,不会对食品造成污染。

The inner cavity of Roots blower does not need lubricating oil, but only needs to add gear oil to the fan gear. In order to reduce friction and noise during operation, the rotary fan will automatically send the lubricating oil to the drip nozzle and drip into the cylinder by using the pressure difference. Therefore, the gas delivered by roots blower is dry and pollution-free; When the rotary blower drops lubricating oil into the cylinder, a small amount of oil will enter the water body, and oil mist will appear at the exhaust port. Therefore, roots blower is better for the food industry when selecting fans, which will not pollute the food.
