1. The brand new lubricating oil system is adopted, and the fan absolutely does not spray oil
On the top of the Roots blower tank, there is a small black object, which is a vent plug device. Its function is very large, it can discharge the trace high-temperature gas leaked into the fuel tank when the fan cavity is pressurized, reduce the pressure and temperature of the fuel tank, and also serve as a lubricant filling hole.
However, due to design problems of traditional Roots blowers, fuel injection often occurs at the vent plug, which pollutes the environment and also causes hidden danger to the quality of the unit due to the oil level reduction caused by fuel injection.
The new NSR series Roots blower uses the national patent "One Roots Blower Lubricating Oil System". It adopts a fully enclosed wall panel, which deviates the vent plug device cleverly to ensure that the fan never sprays oil.
In this way, the equipment maintenance staff no longer need to clean up the dirty and dirty scene! And there is no need to stop the machine to replenish the amount of oil.
2. The fan adopts double fuel tank structure, which increases the service life.
When the traditional Roots blower is under 58.8kPa, the gear side is lubricated with lubricating oil, and the drive side is lubricated with lithium grease. This not only increases the workload of equipment maintenance, but also causes hidden dangers due to uneven quality of lithium-based grease or delayed replacement of fat.
The new NSR series Roots blower adopts double-end double fuel tank design, and the price is unchanged, which is beneficial to the product, preferential to customers, and strives for more stable products.
3. Optimize the impeller profile to save energy and reduce noise
The rotor of the new NSR series Roots blower adopts CAD and CAM assisted design to develop the optimal arrangement of the series spectrum. It is precision-made by a CNC bidirectional surface planer to achieve the best rotor-type meshing with minimal leakage and advanced structure , High efficiency, energy saving, durable and convenient, etc., fully reach the international advanced level.
At the same time, due to the advanced and efficient rotor, the pulse airflow of the fan is greatly reduced, and the noise of the whole machine is also reduced.
4.The cabinet wall panel gains 20% and the vibration is smaller
The new NSR series Roots blowers increase the design margin, increase the weight of the load-bearing structural parts such as the chassis and wall panels by 20% -30%, increase the weight of the fan, and effectively reduce vibration.
The reduction of vibration has greatly improved the service life of the bearings.
5, using GB wearing parts, easy maintenance
All the wearing parts of the new NSR series Roots blower adopt national standard parts, which is convenient for on-site maintenance and replacement. The fan belt pulley is a tensioning sleeve belt pulley, which completely prevents the damage of the bearings due to violent impact when the fan is installed.
