Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of hydraulic station oil tank, specifically a hydraulic station oil tank. BACKGROUND

[0002] The main work of the hydraulic station oil tank is to store oil, and 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 and an overflow valve. The hydraulic station supplies oil according to the flow direction, pressure and flow rate required by the driving device, and is suitable for various machines with separated driving devices and hydraulic stations. The hydraulic station is connected to the driving device (oil cylinder or motor) by an oil pipe, and the hydraulic system can realize various specified actions.

The oil tank has two tanks, and the two tanks are arranged below the oil receiving disc. The oil receiving disc is connected to the two tanks through pipelines provided with valves. One of the tanks is connected to the repair hydraulic station through a pipeline provided with an oil pump, and the other tank is connected to the quality assurance hydraulic station through a pipeline provided with an oil pump. The utility model connects the oil receiving disc to the repair hydraulic station and the quality assurance hydraulic station through two tanks and two sets of conveying pipelines. According to the properties of the detected products, the residual oil can be sent to the corresponding hydraulic station, so that the residual oil after repair detection can be collected in the repair hydraulic station, and the residual oil after quality assurance detection can be collected in the quality assurance hydraulic station. The problem of reducing the quality of oil due to the mixing of different oil is eliminated, and the quality of oil in the two hydraulic stations is guaranteed.

[0004] In the existing hydraulic station system, the use process of the oil tank utilizes pipelines and pumps to apply pressure to the pipelines, thereby realizing the pressurization of the oil in the oil tank.
