【Abstract】 Objective: To explore the influence of targeted maintenance treatment and preventive measures for water pump failures in the cooling system of radiological equipment on pump operational stability and fault recurrence rate. Methods: From January to December 2024, 20 active radiotherapy equipment units in the department’s radiology department that were equipped with cooling system pumps and underwent routine maintenance were selected as the control group. Additionally, from January to December 2025, 20 similar equipment units in the department that underwent targeted maintenance and combined with specialized preventive measures were included in the observation group. The failure handling effectiveness, pump failure frequency, adverse effects on equipment, cooling system operational indicators, and pump performance scores were compared between the two groups. Results: The qualified rate of operating parameters and fault maintenance efficiency of the observation group were higher than those of the control group(P<0.05); The fault recurrence rate and incidence rate of equipment downtime loss of the observation group were lower than those of the control group(P<0.05); The overall operational stability score of the cooling system in the observation group was higher than that in the control group(P<0.05). Conclusion: The implementation of targeted maintenance treatment and preventive measures for water pump failures in the cooling system of radiological equipment can significantly improve pump operational stability and maintenance quality, effectively reduce the risk of fault recurrence, decrease the impact of equipment downtime on diagnosis and treatment, and provide guarantee for the safe operation of radiological equipment.更多还原
