Description

[0002] A small hydraulic power station for a core-making machine is a supporting device that supplies hydraulic fluid to the core-making machine. The hydraulic power station is a hydraulic source device or a hydraulic device including control valves, consisting of a hydraulic pump, a drive motor, an oil tank, directional valves, throttle valves, and relief valves. With the continuous development of technology, people have increasingly higher requirements for the manufacturing process of small hydraulic power stations for core-making machines.
