To ensure the long-term stable operation of chemical pumps and extend their service life, in addition to proper selection, standardized daily maintenance and upkeep are crucial. An effective maintenance plan can effectively prevent malfunctions and reduce losses caused by unexpected shutdowns.
Inspection in daily operations is the first step. The operator should regularly check the operating status of the pump, including whether there is any abnormal vibration or noise, whether the motor current is within the rated range, whether the bearing temperature is normal, and whether there are signs of leakage in the sealing system. Any minor anomaly can be a precursor to a malfunction and needs to be promptly recorded and addressed.
Regular maintenance is key to maintaining performance. This includes:
Lubrication management: Strictly follow the manufacturer's regulations, regularly inspect and replace the lubricating oil in the bearing box to ensure that the bearings are well lubricated.
Sealing inspection: For mechanical seals, attention should be paid to flushing the pipeline smoothly and observing for leaks. Once the leakage exceeds the standard, immediate maintenance and replacement should be arranged.
Performance monitoring: Regularly record parameters such as pump flow rate and head, and compare them with the initial performance curve. If there is a significant decrease in performance, it may indicate that internal components such as impellers and mouth rings have worn out and require disassembly inspection.
Maintenance during long-term disuse is equally important. Before stopping the chemical pump, the medium inside the pump must be thoroughly emptied and cleaned to prevent crystallization or corrosion of the pump body. For parts that are prone to rust, anti rust grease should be applied and regularly turned to prevent the parts from getting stuck.
Establishing a comprehensive equipment maintenance file, recording detailed information on each inspection, maintenance, and repair, helps analyze equipment status, achieve predictive maintenance, and shift equipment management from post repair to pre prevention, laying a solid foundation for the stable, long-term, and optimal operation of chemical production.
