Safety Precautions for Installing a Roots Blower for Pyrolysis Gas Carefully read the user manual and product catalog of the Roots blower to familiarize yourself with its specifications, model, impeller rotation direction, and air flow inlet and outlet directions. Double-check that all components of the Roots blower are in good condition; if any are found to be damaged, repair them before installation and use.
Safety Precautions for Installing a Roots Blower for Pyrolysis Gas
Install Rotary lobe blower for pyrolysis gas At this time, special attention should be paid to the safety of both the machinery and personnel; therefore, the following safety measures should be taken during the installation process:
1. Carefully read the operating manual and product catalog for the Roots blower, and familiarize yourself with its specifications, model types, impeller rotation direction, and air flow inlet and outlet directions. Once again, check whether all components of the Roots blower are in good condition; if not, repair them before installation and use.
2. The Roots blower for pyrolysis gas should be equipped with safety devices to prevent accidents, and its installation and wiring must be carried out by qualified professionals who are familiar with the relevant safety requirements.
3. The ducts connecting the inlet and outlet of the Roots blower shall be supported independently; it is not permitted to place the combined weight of these ducts onto the blower’s components. When installing the Roots blower, pay attention to its horizontal alignment and ensure that the mating surface between the blower and its base is properly aligned with the outlet pipe connection, allowing for a natural fit without forcing the connection.
4. After the Roots blower for pyrolysis gas has been installed, use your hand or a lever to gently rotate the impeller and check whether it is excessively tight or experiences any friction. Also, ensure that there are no objects obstructing its rotation. Only when no abnormalities are detected can you proceed with a trial run. The exposed parts of the Roots blower’s transmission mechanism must be equipped with protective guards. If the Roots blower’s air inlet is not connected to a duct, a protective mesh or other suitable installation device should be added.
5. The electrical control box for the Roots blower must be matched with the corresponding blower (in terms of power, voltage, pneumatic mode, control type, etc.).
Rotary lobe blower for pyrolysis gas What should I do if there’s insufficient runtime?
Roths blowers are often used for sewage aeration, which can lead to insufficient air supply from the blowers. Below is a brief introduction to Shandong San Niu Roots Blower Manufacturer; the main reasons are as follows:
1. The wrong choice
If the wrong selection is made or the pressure is insufficient, it’s normal that aeration cannot be achieved—for example, if we need a Roots blower with a pressure of 44.1 kPa for aeration, it’s perfectly normal for the aeration to fall short when selecting the pressure.
2. Check valve issue
A check valve is a one-way valve that allows gas to escape but not to enter. It’s a single device added specifically to prevent backflow of gas and the entry of impurities into the fan. Since the connection between the check valve and the pipe flange is sealed with a rubber gasket, when the pressure is low, the Roots blower pipeline may leak; however, at higher pressures, the valve closes tightly. After the fan is shut down, the negative pressure generated inside the pipeline causes the valve to close again. The check valve can be removed and reinstalled. However, if the gasket is damaged, the entire check valve must be replaced. When installing the check valve, pay attention to ensure that its outlet direction is not reversed. If installed in the wrong direction, air will not be able to escape, which not only leads to unsuccessful aeration but could also cause the motor to burn out.
3. Fan malfunction itself
The longer a Roots blower is used, the more likely it is for various parameters of the blower—such as insufficient air volume and pressure—to deviate from their original specifications. These deviations are perfectly normal, as the Roots blower experiences wear and tear during operation. Therefore, as the blower’s service life extends, its performance parameters will gradually drift away from their ideal values.
4. Pipeline issues
When using a Roots blower, if pipeline issues arise—for example, the inlet filter might become clogged, or the resistance in the outlet pipe might be too high—leaks may occur during operation, leading to pipe damage and leakage, as well as insufficient pressure. Additionally, if the aeration pipeline is too long or has too many bends, pressure loss can also occur.
5. Circuit issues
It’s possible that the aging of the original factory parts in the power supply circuit has led to insufficient power supply (operating current).
