When using a pump scraper filter, attention should be paid to the following points to ensure the safe and efficient operation of the equipment as well as the safety of the operators:
I. Preparation Before Operation
Read the Instructions in Detail: Before first use, the operation manual or instructions of the equipment should be read carefully to understand the operating procedures, methods, and safety precautions.
Check the Equipment Status: Check whether the equipment and its components are in good condition, confirm that there are no debris left on the filter cloth and rollers, and check whether the filter cloth is positioned correctly and whether the scraper is in proper contact with the filter cloth.
Check Lubrication and Tension: Check whether the gearbox oil is sufficient and whether the filter cloth tension is appropriate, and adjust as needed.
Start the Air Compressor: Activate the control valve of the air compressor's air storage tank to send pressurized air to the pneumatic control unit and adjust the air pressure to set the filter cloth tension.
Check Other Components: Check the air pressure of the air compressor and regulator, slightly move the filter cloth deviation sensing device by hand to test if the cylinder operates normally. Test the functionality of the emergency stop switch. Start the filter cloth washing pump and check if the water volume and pressure meet the requirements.
II. Operation Precautions
Startup Sequence: Start the equipment in the correct order, first starting auxiliary equipment such as the air compressor and filter cloth washing pump, and then the main equipment.
Monitor Operating Status: During equipment operation, closely monitor its operating status, including motor rotation direction, bearing temperature, and filter cloth tension.
Avoid Operational Errors: It is prohibited to perform any maintenance or servicing operations while the equipment is running. Modifying equipment parameters is strictly forbidden to prevent damage to the equipment. Avoid reaching into the equipment casually to prevent injury from the scraper.
Emergency Shutdown: If the equipment exhibits abnormal conditions, such as the filter cloth being unable to return to its normal position or abnormal motor heating, immediately stop the equipment, inspect the issue, and take appropriate measures.
III. Maintenance and Servicing
Regular Cleaning: Regularly clean the filter cloth to keep it clean and dry, thereby extending its lifespan and improving filtration efficiency.
Inspection and Replacement: Regularly inspect the equipment's components, such as bearings, scrapers, and filter cloth, and replace them promptly if worn or damaged.
Lubrication and Adjustment: Regularly lubricate the equipment's lubricating parts to maintain good lubrication. At the same time, adjust the filter cloth tension as needed to ensure stable equipment operation.
Post-Shutdown Handling: When the equipment is not used for an extended period, loosen the filter cloth tension and clean any residues inside the equipment to prevent corrosion and damage.
IV. Safety Precautions
Electrical Safety: The equipment should be equipped with electrical protective devices, and the electrical circuits and switches should be regularly checked for normalcy.
Operational Safety: Operators should wear appropriate protective equipment, such as gloves and protective glasses, to prevent injuries. Additionally, they should adhere to the equipment's operating procedures and safety precautions.
Environmental Safety: The equipment should be placed in a dry, well-ventilated environment to avoid damage from moisture and high temperatures. At the same time, ensure that there are no flammable or explosive materials around the equipment to prevent fires and explosions.
In summary, when using a pump scraper filter, attention needs to be paid to multiple aspects including preparation before operation, operation precautions, maintenance and servicing, and safety precautions. Only by strictly following the operating and maintenance regulations can the safe and efficient operation of the equipment and the safety of the operators be ensured.
