Roots blower is a positive displacement fan, with impeller end face, fan front and rear end covers. The principle is a rotary compressor that uses two blade rotors to make relative movement in the cylinder to compress and transport gas. With simple structure and convenient manufacturing, it is widely used in aquaculture oxygenation, sewage treatment aeration, cement transmission, and more suitable for gas transmission and pressurization in low pressure occasions, and can also be used as a vacuum pump.
First, check every part of Roots blower manufacturer's blower, including some connections of all small parts, as well as installation quality inspection of inlet and exhaust pipes and valves; Carefully check whether the screws of each part are tightened and whether there is any looseness. Pay attention to whether the relevant parts of Roots blower are clean and need to be cleaned.
There must be no additional load between the start of Roots blower, because it may affect the Roots blower; Check the blower and motor for two to three times; Check whether the wiring of the fan is intact. Then check around the base of the unit to see if it is tight; The next step is to refuel the tank. Before refuelling, be sure to check whether the tank leaks oil. The oil must be suitable and appropriate.
In fact, we can do a trial run before the three leaf Roots blower runs to see if there is any obvious noise, and then solve the problem. Before using Roots blower, if you have done the above related debugging, the probability of accidents will be very small. Safety is very important for machine operation. Make preparations for Roots blower before use, which is very conducive to the normal operation of the work and the protection of the operator's personal safety.
1. Check the standby machine equipment of Roots blower system and prepare for full startup. Check the main power switch of the valve of the standby Roots blower to ensure that the outlet valve of the Roots blower is fully closed and the safety passage valve is fully opened.
2. The standby fan of Roots blower starts and the fan stops. When the standby fan is in normal operation, slowly close the outlet of the machine and equipment and disconnect the circuit of the standby fan. The secondary coil pipeline valve of the auxiliary fan is gradually closed, so the outlet working pressure is slightly higher than the working pressure of the fan to be stopped.
3. Gradually open the secondary pipe valve of the fan, and gradually close the outlet valve of the applied fan to make the outlet working pressure slightly higher than the original outlet working pressure. During the whole process, the working pressure of the fan working pressure outlet shall be kept balanced to ensure the reliability coefficient of the system working pressure. Gradually close the secondary valve and outlet valve of roots blower until they are fully closed, and open the secondary valve and outlet valve of standby roots blower until they are fully opened. At this time, the operation process of machinery and equipment stops, and the transformation operation process of Roots blower is completed.
I believe that after reading the above, you should also know what preparations need to be made before Roots blower starts to work. I hope it will be helpful to you.
