Start of Roots blower
The start-up of Roots blower is a process that requires careful operation. The following are detailed start-up steps and precautions:
Startup steps
1、 Inspection and preparation:
1. Check if the power supply and connections of each part of the equipment are good, and also check if there are any abnormalities in the electrical control system.
2. Confirm that the inlet and outlet pipelines, as well as auxiliary equipment such as vent valves, are in the correct installation state and there are no leaks.
3. Ensure that the inlet valve (usually the suction port) is in the open state, the outlet valve (the valve on the exhaust pipeline) is in the closed state, and the vent valve is also in the closed state to prevent damage or dangerous situations caused by turbulent airflow when not in operation.
2、 Starting motor:
1. According to the instructions of the electronic control system, the motor is usually started first.
2. Observe whether the rotation direction of the fan is correct. If it is not correct, adjust the direction of rotation in a timely manner to ensure normal operation.
3、 Formal operation:
1. After the motor is started and the fan rotates in the correct direction, the fan can be officially started.
2. It should be noted that during the start-up process, constant attention should be paid to the changes in various data, such as the indication value of the ammeter, to ensure that it does not exceed the rated value.
3. When the pressure reaches the desired value, the outlet valve can be gradually opened and the inlet guide vane angle can be adjusted to put the fan into normal operation.
matters needing attention
1. During the start-up process, it is essential to ensure personnel safety and avoid accidents such as electric shock or mechanical injury.
2. Lubrication and cooling: Before starting, check whether the lubrication system and cooling water system are intact to ensure that the fan can receive sufficient lubrication and cooling during operation.
3. Observation and recording: After starting, closely observe the operation of the fan, including sound, vibration, temperature, etc., and record relevant data for subsequent analysis and maintenance.
4. Troubleshooting: If abnormal sounds, odors, or vibrations are found, the machine should be stopped immediately for inspection and troubleshooting before resuming operation.
5. Shutdown operation: Before shutting down, the load should be reduced or removed, and the power should be cut off after the fan stops.
In summary, the start-up process of Roots blower needs to be strictly carried out in accordance with the operating procedures to ensure the stable operation of the equipment. At the same time, close attention should be paid to changes in various data during the startup process, and potential problems should be identified and addressed in a timely manner.
