Three-lobe Roots blower switching operation and filter element removal

How to switch the three leaf roots blower:


Ensure that the valve switch of the standby system of the three blade roots blower is in place, the discharge valve of the three blade roots blower is completely closed, and the inlet valve is fully opened.


If the inspection is normal, please open the backup system of three leaf roots blower according to the operation steps. At the same time, the standby fan of the three leaf roots blower starts and the current fan stops. If the standby fan works normally, please slowly turn off the power socket of the equipment and disconnect the circuit of the standby fan. At the same time, the auxiliary pipeline valve of the standby fan is gradually closed, so the outlet pressure is slightly higher than the working pressure of the fan outlet to be stopped. During the above operation, slowly open the pipeline valve of the auxiliary fan and slowly close the outlet valve of the used fan to make the outlet pressure slightly higher than the original outlet working pressure.


Throughout the process, you need to maintain the pressure at the fan pressure outlet and keep the system pressure as stable as possible. Gradually close the secondary line valve and outlet valve of the three blade roots blower until they are completely closed and opened, until the secondary line valve and outlet valve of the standby three blade roots blower are fully opened.


The features of the three blade roots blower are as follows:


1. Double tank design:


Compared with the single tank fan using grease lubrication, the lubrication mode is changed. Due to the use of oil lubrication at both ends, the lubrication is more sufficient, the service life of bearings is significantly improved, and the frequency of rotor damage caused by bearing damage is avoided.


2. Low noise:


As the lubrication is more sufficient, the mechanical noise of fan with single oil tank is obviously reduced by 6-8 dB.


3. Low temperature and high strength


Because most of the mechanical parts are completely immersed in lubricating oil, it can effectively reduce the fan temperature and strengthen the mechanical fatigue strength of the main parts of the fan.


4. Simple maintenance:


As the traditional single tank fan adopts the way of injecting grease at the driving end, the maintenance requirements are relatively high in the process of use, especially when the grease needs to be injected from the top of the fan oil tank, the actual grease loss can not be observed from the outside of the fan, and the grease loss can be judged by the experience of the maintenance personnel.
