[0002] Existing compressed gas refueling equipment, such as CNG hydraulic level fader station, the control points related to the fuel tank level gauge are in the form of fixed dry nodes. Once the oil volume in the fuel tank changes, the system cannot realize automatic adjustment, resulting in Substation trailer unloading rate reduced
Moreover, the longer the normal operation time of the existing sub-stations, the greater the loss of medium oil, which will lead to an increase in the residual gas in the gas cylinders of the trailers of the sub-stations, which will further lead to an increase in the residual pressure of the gas cylinders of the trailers of the sub-stations, and the unloading Gas rate decreases, gas loss increases

The invention discloses a medium oil compensation system of a gas filling substation and a medium oil compensation method of a gas filling substation. The medium oil compensation system of a gas filling substation is set in a gas filling substation, and the gas filling substation includes a gas cylinder, a fuel tank, and a fuel tank The medium oil can be filled into the gas cylinder through the power mechanism through the oil injection pipeline, and the gas cylinder can return the medium oil to the oil tank through the power mechanism through the oil return pipeline. The medium oil compensation system of the gas filling sub-station includes a pressure detection module and a calculation control module The pressure detection module can respectively measure the first pressure in the gas cylinder after the medium oil with the volume of the design value is filled into the gas cylinder, and the first pressure in the gas cylinder after the medium oil with the volume of the design value returns to the oil tank. Two pressure: the calculation control module is connected to the power mechanism, and the calculation control mechanism can calculate the volume of a compensation value of the medium oil according to the first pressure and the second pressure, and use the sum of the volume of the compensation value and the volume of the design value as Fill the volume of the actual value of the medium oil.
Description
technical field [0001] The invention relates to the technical field of compressed gas refueling equipment, specifically, a medium oil compensation system for a gas filling sub-station and a medium oil compensation method for a gas filling sub-station are designed. Background technique [0002] Existing compressed gas refueling equipment, such as CNG hydraulic level fader station, the control points related to the fuel tank level gauge are in the form of fixed dry nodes. Once the oil volume in the fuel tank changes, the system cannot realize automatic adjustment, resulting in Substation trailer unloading rate decreased. Moreover, the longer the normal operation time of the existing sub-stations, the greater the loss of medium oil, which will lead to an increase in the residual gas in the gas cylinders of the trailers of the sub-stations, which will further lead to an increase in the residual pressure of the gas cylinders of the trailers of the sub-stations, and the unloading ...
