The device mainly comprises two parts, namely a pipeline system and an electric control system of the filling device. The pipeline system mainly conveys hydrogen into the hydrogenation device from a hydrogen storage tank or a hydrogen compressor (an air source inlet),
the hydrogen energy is added into the hydrogen energy automobile through devices such as a gas filter, an electromagnetic valve, a flowmeter, a breaking valve, a hydrogenation hose, a hydrogenation gun and the like on a pipeline. Due to different pressure grades (at present, 35Mpa is mainly used domestically, and the development direction of a foreign hydrogenation machine such as japan is referred, and the future development is further 70Mpa), the device is specially designed with hydrogenation guns with two pressures (hydrogen energy automobiles with two pressures can be respectively filled), and the pipeline system shares most parts (such as a gas filter, an electromagnetic valve and a mass flow meter) and is different from a breaking valve, a hydrogenation hose and a hydrogenation gun. Moreover, the switching of the two pressures needs manual control of valve adjustment, and a control system is also needed to confirm that the filling can be carried out later (the pressure is 35MPa and 70MPa are distinguished).
In the electric control system, a central controller is used for acquiring data which are uploaded to the device by a mass flow meter, a pressure transmitter, a temperature transmitter and a 70Mpa hydrogen energy automobile gas storage cylinder (70 MPa of an automobile hydrogenation communication port in figure 1), and controlling an electromagnetic valve to realize the whole filling process. And the data of the leakage alarm on the device and the data of the device can be uploaded to a station control system of the hydrogen station, so that control supervision is realized, the working efficiency is improved, and the operation cost is reduced.
The filling control management process comprises the following steps:
the filling device has the gas filling condition (a gas filler inserts the hydrogenation gun and presses a gas filling key on the keyboard); the filling device is detected through a hydrogenation port (whether communication exists or not, whether 35Mpa or 70MPa injection exists is judged, 70Mpa hydrogen energy automobile hydrogenation port is communicated, and 35Mpa hydrogen energy automobile hydrogenation port is not communicated); then controlling the switching valve to open (without communication, opening the 35MPa pipeline, closing the 70MPa pipeline, and with communication, opening the 70Ma pipeline and closing the 35MPa pipeline); then controlling the electromagnetic valve at the air inlet part to open for filling; the data of the medium pressure conditions (if the medium pressure is filled under 70Mpa, the data of a hydrogen energy automobile can be collected) are monitored by a mass flow meter, a pressure transmitter and a temperature transmitter in real time, are processed by a central controller and are displayed on a main display and a customer display; judging whether filling is finished or not by detecting the flow rate of the mass flowmeter and the data acquired by the pressure transmitter; after filling, the electromagnetic valve at the gas inlet is closed, the gas filler opens the hydrogenation gun to deflate and release the pressure, and the hydrogenation gun is drawn out to complete the one-time filling process.
