The invention relates to the technical field of vacuum pump control, and discloses an electric vacuum pump control method and device and a storage medium. The electric vacuum pump is controlled to continuously work until the accumulated working duration reaches a second preset duration, and a second pressure value is obtained; determining a vacuum pump leakage fault type according to a pressure interval formed by the first pressure value and the second pressure value; determining a leakage level corresponding to the vacuum pump leakage fault type according to the second pressure value; and executing a corresponding fault processing strategy according to the vacuum pump leakage fault type and the leakage level. The leakage fault type and the corresponding leakage level of the vacuum pump are determined according to the pressure value of the vacuum tank, the corresponding fault processing strategy is executed, the problem that the vacuum pump cannot achieve multi-level fine control is solved, sufficient operation time is provided, accurate control over different leakage degrees is achieved, and high-load operation is avoided.
本发明涉及真空泵控制技术领域,公开了一种电动真空泵控制方法、设备及存储介质,该方法包括:当电动真空泵累计工作时长达到第一预设时长且第一压力值未达到预设阈值时,控制电动真空泵持续工作直至累计工作时长达到第二预设时长,获取第二压力值;根据第一压力值与第二压力值组成的压力区间确定真空泵泄露故障类型;根据第二压力值确定真空泵泄露故障类型对应的泄露层级;根据真空泵泄露故障类型以及泄露层级执行对应的故障处理策略。本发明通过根据真空罐的压力值确定真空泵泄露故障类型以及对应的泄露层级并执行对应的故障处理策略,解决真空泵无法实现多层级精细控制的问题,提供充足运行时间和对不同泄漏程度实现精准控制,避免高负荷运行。
