The daily maintenance and care of pulse jet bag filters are crucial for ensuring their efficient and stable operation. By implementing detailed maintenance measures, you can effectively extend the lifespan of the equipment and improve dust collection efficiency. Below is a detailed explanation from Darko regarding the daily maintenance and care of pulse bag dust collectors:
1. Regular Inspection and Recording
1.Monitoring Operating Parameters
Regularly check and record the inlet and outlet temperatures of the dust collector, as well as the main fan current. Pay special attention to temperature changes to prevent high temperatures from damaging the filter bags. It is advisable to record the pressure differential in the dust chamber and the inlet temperature every hour, addressing any anomalies promptly.
2.Checking the Cleaning System
When using a timed cleaning controller, regularly verify that the cleaning cycle is accurate and make necessary adjustments. If using a differential pressure pulse controller, check for blockages in the pressure switch and measurement ports, ensuring they remain clean.
2. Maintenance of Filter Bags
1.Inspecting Filter Bags
Regularly check the condition of the sacs filtrants for any damage, blockage, or caking issues. If any damage is found, replace the bags promptly to ensure their cleanliness and permeability.
2.Manual Cleaning
During downtime, perform manual cleaning of the dust collector to remove dust from the filter bags, preventing moisture-related caking.
3.Washing and Replacing
Based on the dust collection volume and the condition of the filter bags, regularly wash the bags and replace any that have aged.
3. Maintenance of the Cleaning System
1.Checking the Pulse Valve
Regularly inspect the operational status of the pulse valves. If any faults or membrane damage are detected, address them immediately or replace the valves to ensure that the blowing pressure remains within the standard range for effective cleaning.
2.Inspecting the Blowing Pipes
Periodically check the position of the pulse blowing pipes and perform necessary maintenance to avoid damage to the filter bags due to looseness, misalignment, or disconnection.
4. Maintenance of Other Components
1.Oil-Water Separator and Oil Mist Lubricator
Regularly check the oil-water separator and the filter's gas bag, draining it once per shift. Frequently check the oil level in the oil mist lubricator and refill as necessary.
2.Lubricating Components
Regularly inspect the lubrication status of cylinders, bearings, and other components, promptly adding or replacing lubricating oil as needed. Change the grease in the cycloidal pinwheel reducer every six months, and replenish the lubrication points of the bearings weekly.
3.Sealing and Leak Checks
Regularly inspect the sealing conditions of cylinders, solenoid valves, flange surfaces, and maintenance doors. Replace any aging seals or address any leaks found. Additionally, check for leaks in the compressed air pipeline and ensure the gap when the lifting valve is closed is appropriate.
4.Hopper and Ash Discharge Device
Each work shift, check the ash discharge situation in the dust collector's hopper to ensure that the ash does not exceed one-third of the hopper's height. The ash discharge device must not stop working during normal operation to prevent dust accumulation in the hopper.
5. Precautions During Shutdown and Startup
1.During Shutdown
After the process system stops, keep the bag dust collector and exhaust fan running for a while to clear moisture and dust from the equipment. After shutdown, repeatedly clean the dust collector's hopper to prevent moisture from affecting the filter bags.
2.During Startup
Before starting, connect the compressed air to the storage tank, turn on the control power, and start the ash discharge device. If there are other devices in the system, start the downstream equipment first.
6. Additional Considerations
1.Electrical Component Checks
Regularly inspect the operational status of electrical components, motors, and control cabinets to ensure safe operation.
2.Preventing Combustion and Explosion
Take special precautions to prevent combustion, explosions, and fire accidents, such as installing a combustion chamber or spark arrestor before the dust collector.
3.Professional Training
Provide professional training for operators to familiarize them with the equipment's working principles, operating procedures, and maintenance methods, enhancing the efficiency and safety of the equipment.
By following these detailed maintenance and care measures, you can ensure the long-term stable operation and high dust collection performance of pulse bag dust collectors.
