Operating Procedures for Pyrolysis Gas Roots Blowers When operating a pyrolysis gas Roots blower, the air volume of the blower should be adjusted according to the oxygen demand of the aeration tank. In the event of abnormal conditions such as a sudden power failure in the blower’s water or oil cooling system, immediate measures must be taken to ensure that the blower does not malfunction.
Rotary Lobe Blower Operation Procedures for Pyrolysis Gas
Use Rotary lobe blower for pyrolysis gas At this time, the air volume of the blower should be adjusted according to the oxygen demand of the aeration tank. In the event of abnormal conditions such as a sudden power failure in the blower’s water or oil cooling system, immediate measures must be taken to ensure that the blower does not malfunction.
Rotary lobe blower for pyrolysis gas During operation, operators should monitor the fan and motor’s air pressure, oil temperature, oil pressure, air volume, current, and voltage, and record these readings promptly. If any abnormal conditions cannot be resolved, immediately stop the machine. Regularly check whether the cooling and lubrication systems are unobstructed and whether the temperature, pressure, and flow rate meet the required specifications.
I. Preparations and Inspections Before Driving
The voltage fluctuation should be within the range of 380V ±10%; the three-phase power supply must not have any phase missing. Instruments and electrical equipment should be in good condition, and electrical equipment requiring grounding must be reliably grounded. Connections to fan ducts and foundation bolts, among others, should be securely tightened. The lubricating oil in the gearbox must be of the specified brand and should be added up to the oil-level mark. Before starting, manually rotate the pulley 2–3 times to check for any abnormal conditions. The outlet valve of the fan should be closed, while the exhaust valve should be fully open.
II. Power-On Operation
Open the vent valve and the air outlet valve; turn on the power supply. After 30 seconds, if no abnormal conditions—such as metal friction or excessive current—are detected, gradually close the vent valve to bring the system into normal operation. During normal operation, the outlet valve must not be closed to prevent potential rupture accidents. If several fans are started simultaneously, first start one fan and allow it to run under no-load conditions until it operates normally. Once the first fan is running normally (for 30 seconds), then proceed to start another fan. After the second fan also runs normally under no-load conditions (for 30 seconds), close the vent valve.
III. Shutdown Procedure
Before shutting down, make a thorough record, noting data such as voltage, current, air pressure, temperature, and operating time. Gradually open the exhaust valve; press the stop button; then close the exhaust valve.
IV. Inspection of the Fan
After the fan is running normally, inspect it once every hour and record the meter readings (voltage, current, wind pressure, temperature, etc.). Inspect every 2 to 3 hours. During inspections, pay attention to whether the fan’s sound is normal; there should be no friction noises during operation. If any abnormalities are detected, immediately stop the machine and perform an inspection.
Five, Rotary lobe blower for pyrolysis gas maintenance of
To ensure proper daily maintenance, the fan room should be kept clean and well-ventilated, with no dust or oil stains on the surface of the equipment. Regularly (monthly), check the tightness of all connecting bolts on the fan. After operation or major overhauls, the lubricating oil in the Roots blower’s oil tank must be completely replaced after 48 hours of operation. When the fan has been running continuously for more than 500 hours, the oil should be changed immediately. The standby fan should be started at least once a week; typically, after running for 10 hours, it should be switched with the standby fan to extend the service life of both fans. Under normal conditions, the fan should be inspected every 500 hours, undergo minor maintenance every 2,000 hours, medium maintenance every 3,000 hours, and major overhaul every 15,000 hours.
Alright, I won’t go into further details. Our company offers a wide variety of fans—please feel free to give us a call if you’re interested.
