  • Patent number: 12152592
    Abstract: According to the disclosure, a pump unit includes a vibration sensor or a noise sensor, and a controller may control a driving operation of a pump driving unit on the basis of vibration data or noise data. Furthermore, in case that pump driving units are provided, control is performed to adjust a fault threshold value in consideration of influence of vibration or noise therebetween, and thus the reliability of detection or diagnosis of a fault of a pump can be improved, and the safety of an operator can be promoted.
