What happens when a hydraulic system needs energy?

Energy Release: When the hydraulic system requires energy, the compressed gas expands, pushing the hydraulic fluid back into the system and thus converting the stored potential energy back into kinetic energy.

What is the future of data collection system of hydraulic machinery?

With the development of data collection technology and the guidance of growing market demand, the data collection system of hydraulic machinery will be developed in the direction of miniaturization, information, and intelligence. The future sensor detection and diagnosis system will be an integrated, Internet-based remote diagnosis system.

Does a hydraulic lift require a lot of energy?

In the case of a hydraulic lift or hydraulic crane, a large amount of energy is required when the lift or crane is moving upward. This energy is supplied from the hydraulic accumulator. But when the lift is moving in the downward direction, it does not require a huge amount of energy.

Do hydropower stations have online monitoring and fault diagnosis systems?

At present, large and medium-sized hydropower stations have installed online monitoring and fault diagnosis systems for hydropower units. However, these systems all have the defects of the data island and single service.

How artificial intelligence can improve hydropower fault diagnosis?

With the continuous development and integration of artificial intelligence and big data analysis technology, more and more intelligent algorithms have been introduced into the field of fault diagnosis of hydropower units, and a series of research results has been achieved.

Can a neural network predict the vibration trend of a hydraulic turbine?

Liu proposed a multipart nonlinear trend prediction method based on variational modal decomposition and the convolutional neural network to predict the vibration trend of the top cover of the hydraulic turbine. Neural networks are widely used in time series prediction mainly for the following reasons.
