Roots blower According to the theory of fluid mechanics, the flow process of gas will be accompanied by loss. For example, after the gas flows through the throttling device, the pressure of the gas flow will decrease accordingly, that is, they will lose the useful work of the fan. Because all this happened in the process of Roots blower conveying gas, it is a waste of fan energy. The working point of Roots blower is the intersection of the performance curve of the blower at a certain speed and the resistance characteristic line of the pipe network. When Roots blower is actually running, it does not always stay at the design working condition point. It will change with the user's needs or changes in external conditions, that is, Roots blower is actually working under variable working conditions. In order to make the air pressure or air volume of the fan reach a certain target value, it is necessary to manually control the roots blower or pipe network, also known as regulation. Through effective regulation, it can not only meet the requirements of production on flow or pressure, but also maximize energy saving under the condition that Roots blower can work stably.
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 contents, you should also have a better understanding of the items that need to be tested before the Roots blower runs. I hope it will be helpful to you.
