高压罗茨风机是容积式风机，无内压缩，输送气体具有强制性，随着压力的变化风量变化很小。输出空气清洁，不含任何油脂灰尘。机壳内部无需油类润滑，且采用了避免轴承、齿轮轮滑油进入机壳内部的结构设计。显著特点：风量大、压力高、噪音小、性能稳定、经久耐用！

　　The high-pressure Roots blower is a positive displacement fan without internal compression, and it has a mandatory gas conveying function. The air volume changes very little with the change of pressure. The output air is clean and free of any grease or dust. There is no need for oil lubrication inside the casing, and a structural design is adopted to prevent bearing and gear wheel lubricating oil from entering the interior of the casing. Significant features: high air volume, high pressure, low noise, stable performance, and durability!

　　真空吸附的应用技术原理

　　Principles of Application Technology for Vacuum Adsorption

　　利用高压罗茨风机产生的无脉动吸力，将薄片工件与压力机工作台之间的空气抽去，以确保工件与工作台表面牢牢地贴紧；利用吸力将砂轮机磨下的金属屑、吸除，然后再转送到布袋内收集起来。在邮电通讯业，利用吸力将信件吸到分信台上。在食品工业中，对于粉状食品可采用吸力将包装袋两边吸住 ，并自动打开袋口灌入食品进行包装；还可以利用吸力将标签纸吸起，贴在不规则的包装瓶的表面，使其不起皱、拱起或起泡。利用吸力将非磁性材料如塑料、木板和陶瓷制品等吸持在工作台上，以取代机械夹持法，使制品表面免遭损坏。在干洗衣服行业，利用吸力将粘有灰尘的清洁剂从衣服上除去。在服装加工行业，对人体模型进行抽真空，使套在模型上的服装与模型紧密贴合，然后通过蒸汽熨烫使服装挺括。在医药卫生行业，利用高压风机吸力，用不锈钢管吸头为病人吸痰；中吸除血水；还可近抽掉药瓶中部分空气，以使粉剂迅速地装入瓶内。

　　Using the non pulsating suction force generated by the high-pressure Roots blower, the air between the thin sheet workpiece and the press worktable is extracted to ensure that the workpiece is firmly attached to the surface of the worktable; Use suction to remove the metal shavings ground by the grinder, and then transfer them to a bag for collection. In the postal and telecommunications industry, letters are sucked onto the distribution desk using suction. In the food industry, for powdered food, suction can be used to hold both sides of the packaging bag and automatically open the bag mouth to pour in the food for packaging; You can also use suction to lift the label paper and stick it on the surface of irregular packaging bottles, so that they do not wrinkle, arch or bubble. Using suction to hold non-magnetic materials such as plastic, wooden boards, and ceramic products on the workbench, replacing mechanical clamping methods, to prevent damage to the surface of the products. In the dry cleaning industry, using suction to remove dusty cleaning agents from clothes. In the clothing processing industry, the human body model is vacuumed to ensure a tight fit between the garment and the model, and then the garment is straightened by steam ironing. In the medical and health industry, using high-pressure fan suction and stainless steel tube suction tips to suction phlegm from patients; Remove blood water by suction; You can also extract some of the air from the medicine bottle to quickly fill the powder into the bottle.

　　在印刷行业中，利用高压罗茨风机的吸力和压力可将堆积时间过久的纸张一张张分开，以避免相互粘附，并可进行自动高速收集和传送；利用高压风机产生的吸力，还可将刚从印刷机中出来的纸张吸持在滚轮上，以在运往堆积延缓其行进速度；大型晒相要利用高压罗茨风机产生的吸力吸持胶片，使胶片或已感光的印刷电路板与晒相要的平打保持紧密贴合，既平整又保证晒相效果良好。纺织工业中，利用吸力可将织物从车锭上吸下，并可拉紧棉纱，除去棉绒；还可将修剪布料时所产生的布碎、棉绒等吸除，这样既可保持环境清洁，可防止卷布机机件因布碎积聚而遭损坏。

　　In the printing industry, the suction and pressure of high-pressure Roots blowers can be used to separate paper that has been stacked for too long one by one to avoid mutual adhesion, and automatic high-speed collection and transportation can be carried out; By utilizing the suction generated by the high-pressure fan, the paper that has just come out of the printing machine can be held onto the rollers to slow down its movement during transportation and stacking; Large scale photo lithography requires the use of a high-pressure Roots blower to suction and hold the film, ensuring that the film or printed circuit board that has been photosensitive is tightly adhered to the desired surface for photo lithography, which is both flat and ensures good photo lithography results. In the textile industry, suction can be used to pull fabrics off the spindle and tighten cotton yarn to remove lint; It is also possible to remove the debris and lint generated during fabric trimming, which can keep the environment clean and prevent damage to the rolling machine parts due to the accumulation of debris.

　　高压罗茨风机可以用于粉粒体输送、纺织维集尘、裁纸机气垫、污水处理曝气、工业矿业空气、重油喷燃、造纸纸浆脱水、无梭织布等等领域中大量使用。

　　High pressure Roots blower can be widely used in various fields such as powder conveying, textile dust collection, paper cutting machine air cushion, sewage treatment aeration, industrial mining air, heavy oil jet combustion, paper pulp dewatering, shuttle free weaving, etc.

　　使用操作

　　Usage and Operation

　　1、应对风机各部件全面进行检查，机件是否完整，各螺栓、螺母的连接松紧情况、各紧固件和定位销的安装质量、进排气管道和阀门安装质量等。

　　1. A comprehensive inspection should be conducted on all components of the fan to ensure their completeness, including the tightness of bolts and nuts, the installation quality of fasteners and locating pins, as well as the installation quality of intake and exhaust pipes and valves.

　　2、为了保证鼓风机安全运行，不允许承载管道、阀门、框架等外加负荷。

　　2. To ensure the safe operation of the blower, it is not allowed to carry external loads such as pipes, valves, frames, etc.

　　3、检查鼓风机与电动机的找中、找正质量。

　　3. Check the centering and alignment quality of the blower and motor.

　　4、检查机组的底座四周是否全部垫实，地脚螺栓是否紧固。

　　4. Check whether the base of the unit is fully padded around and whether the anchor bolts are tightened.

　　5、向油箱注入规定牌号之机械油至油位线之中，润滑油牌号为N220的中负荷工作齿轮油。

　　5. Inject the specified grade of mechanical oil into the oil tank until it reaches the oil level line, and use N220 medium load working gear oil as the lubricating oil.

　　6、检查电动机转向是否符合指向要求。

　　6. Check if the direction of the electric motor meets the directional requirements.

　　7、在皮带轮（联轴器）处应安装皮带罩（防护罩），以保证操作使用的安全。

　　7. A belt cover (protective cover) should be installed at the pulley (coupling) to ensure safe operation and use.

　　8、全部打开鼓风机进、排气口阀门，盘动风机转子，应转动灵活，无撞击和磨擦等现象，确认一切正常情况下，方可启动风机进行试运转使用。

　　8. Open all the inlet and outlet valves of the blower, rotate the fan rotor flexibly without any impact or friction, and confirm that everything is normal before starting the fan for trial operation.

　　9、鼓风机空负荷试运转

　　9. Empty load test run of blower

　　⑴新安装或大修后的风机都应经过空负荷试运转。

　　Newly installed or overhauled fans should undergo no-load testing.

　　⑵罗茨鼓风机空负荷运转的概念是：在进排气口阀门全开的条件下投入运转。

　　The concept of no-load operation of Roots blower is to put it into operation with the inlet and outlet valves fully open.

　　⑶没有不正常的气味或冒烟现象及碰撞或摩擦声，轴承部位的径向振动速度不大于6.3mm/s。

　　⑶ There is no abnormal odor, smoking phenomenon, collision or friction sound, and the radial vibration velocity of the bearing part is not greater than 6.3mm/s.

　　⑷空负荷运行30分钟左右，如情况正常，即可投入带负荷运转，如发现运行不正常，进行检查排除后仍需做空负荷试运转。

　　⑷ Run under no-load for about 30 minutes. If the situation is normal, you can start running under load. If any abnormal operation is found, check and eliminate it, and then test run under short load.

　　10、鼓风机正常带负荷持续运转

　　10. The blower is running continuously with load normally

　　⑴要求逐步缓慢地调节，带上负荷直至额定负荷，不允许一次即调节至额定负荷。

　　⑴ It is required to gradually and slowly adjust the load until it reaches the rated load, and it is not allowed to adjust it to the rated load at once.

　　⑵所谓额定负荷，系指进、排气口之间的静压差，按铭牌上的标定压力值。在排气口压力正常情况下，须注意进气口的压力变化，以免超负荷。

　　The so-called rated load refers to the static pressure difference between the intake and exhaust ports, according to the calibrated pressure value on the nameplate. Under normal exhaust pressure conditions, attention should be paid to changes in intake pressure to avoid overloading.

　　⑶风机正常工作中，严禁*关闭进、排气口阀门，应注意定期观察压力情况，超负荷时安全阀是否动作排气，否则应及时调整安全阀，不准超负荷运行。

　　During normal operation of the fan, it is strictly prohibited to close the inlet and outlet valves. It is important to regularly observe the pressure situation and ensure that the safety valve operates to exhaust when overloaded. Otherwise, the safety valve should be adjusted promptly and overloading operation is not allowed.
