Description

Technical Field

[0001] The utility model relates to the technical field of hydraulic stations, in particular to a hydraulic station for noise reduction and energy saving tests. Background Art

[0002] The hydraulic station is a hydraulic source device or a hydraulic device including a control valve, which is composed of a hydraulic pump, a driving motor, an oil tank, a directional valve, a throttle valve, a relief valve, etc. The oil is supplied according to the flow direction, pressure and flow required by the driving device. It is suitable for various machines where the driving device is separated from the hydraulic station. The hydraulic station is connected to the driving device (cylinder or motor) with an oil pipe, and the hydraulic system can achieve various prescribed actions. The application of a power hydraulic station with a noise reduction structure is becoming more and more extensive. Therefore, the demand for a power hydraulic station with a noise reduction structure is growing.

[0003] Publication (Announcement) No.: CN220060121U discloses an energy-saving hydraulic station. Through the arrangement of a sedimentation filter element, a center tube and a fine filter tube, oil and dirt enter the sedimentation filter element of the center tube through the opening along with the circulation of the oil. Large particles of dust are blocked by the sedimentation filter element and are difficult to enter the next circulation, and fall and settle into the bottom of the sedimentation filter element. At the same time, fine metal particles can be blocked by the fine filter tube and are deposited at the bottom of the center tube, which is beneficial to avoid increasing the floor space, and is beneficial to effectively capture and precipitate metal debris in the oil of the hydraulic station, and is beneficial to avoid concentrated oil clogging the pipeline and affecting the circulation of the oil. Through the arrangement of the cover, the center tube, the sedimentation filter element and the fine filter tube, the cover is opened to take out the sedimentation filter element, and then the sedimentation filter element, as well as the bottom of the center tube and the fine filter tube are cleaned, so that some oil and metal particles in the oil can be cleaned, thereby improving the circulation efficiency of the oil.

[0004] In the above patent, since the noise of the hydraulic station is too loud during operation and it does not have the function of noise reduction, it is easy to cause noise pollution, and the filtering effect is poor, which easily increases the oil sediment and increases the energy consumption of the hydraulic station. Therefore, it is necessary to provide a hydraulic station for noise reduction and energy saving testing. Utility Model Content
