[0036] 1. Roots blower control screen
[0037] The first-level menu has an automatic start / stop button.
[0038] Click the first-level button to pop up the second-level button (execute / pause / terminate / step 5 minutes / close), click the second-level button to pop up a confirmation dialog box, click to confirm or cancel to choose whether to execute the command.
[0039] The second-level menu is equipped with buttons such as execute, pause, terminate, step, and close.
[0040] 1) Execution: Execute automatic start / stop steps;
[0041] 2) Pause: the program is paused at the current step, and the button becomes continue after clicking, and the program before the pause can be continued at the current position by clicking continue. If a fault is found during the automatic start-up process, use this button when you need to observe and deal with it;
[0042] 3) Termination: The program terminates execution, unable to continue, and stops automatic booting. Use this button if a fault t...

The invention discloses a control method of an automatic starting and stopping system of a Roots blower, and relates to the technical field of networking starting and stopping of blowers. The control method of the automatic starting and stopping system of the Roots blower comprises a starting method and comprises a Roots blower system, the Roots blower system comprises an inlet pipe, an outlet pipe and a to-be-started Roots blower, an outlet of the to-be-started Roots blower is communicated with the outlet pipe, an inlet of the to-be-started Roots blower is communicated with the inlet pipe, and an outlet of the to-be-started Roots blower is communicated with the outlet pipe. An inlet valve is arranged between the inlet of the Roots blower to be started and the inlet pipe, an outlet valve is arranged between the outlet of the Roots blower to be started and the outlet pipe, and a return valve is arranged between the inlet and the outlet of the Roots blower to be started. According to the control method of the automatic starting and stopping system of the Roots blower, the pressure of an outlet of the Roots blower is compared with the pressure of a pipe network, and the Roots blower is matched with a return valve, so that the control method of the automatic starting and stopping system of the Roots blower, which can keep the pressure stable and can quickly respond, is designed.
Description
technical field [0001] The invention relates to the technical field of fan networking start-stop, in particular to a control method for an automatic start-stop system of a Roots blower. Background technique [0002] The Roots blower boosts the pressure of the raw coke oven gas to about 25KPa, and after cooling, desulfurization and other processes, the refined coke oven gas at 21±1KPa is finally delivered to the user. Since the Roots blower is a volumetric unit, it is very difficult to maintain the pressure of the pipe network when starting and stopping, and switching units. It is necessary to open the front and return valves before starting the machine, and slowly close the return valve after starting to increase the pressure. When the unit pressure When the pressure is equal to the pressure of the pipe network, slowly open the outlet valve to realize the connection between the unit and the pipe network. The speed of boosting the pressure and the timing of opening the outle...
