(1) The analog signal of the first and second controllers outputted by the DCS is applied to the first and second intake valves, and the amount of gas compression is controlled by controlling the opening and closing time of the intake valve.
(2) The valve cavity temperature signal fed back by the hydraulic actuator is transmitted to the DCS, and the CIU-ERROR and CIU-WARNING signals are transmitted to the DCS.
(3) The CIU can be configured and tested by connecting a laptop via RS-232.
The hydraulic actuator HA (8 in total, 4 in the first stage cylinder and 4 in the second stage cylinder) is the sum of the components that act on the air valve through the unloader. The valve chamber, the sealing chamber and the electric chamber are three parts. composition. The HU provides the hydraulic power required to achieve this action, the CIU performs real-time signal transmission, and the EPS provides solenoid valve power.
The hydraulic oil station HU (1 set) hydraulic oil station HU provides high-pressure hydraulic oil to provide mechanical power to the actuator HA, and the hydraulic oil pressure is raised from normal pressure to about 5Mpa by the function of the built-in gear oil pump (accurate setting depends on compression) The highest level of intake pressure controlled in the machine). A diaphragm accumulator is installed on the hydraulic oil supply and return lines to stabilize the oil pressure. The hydraulic pressure and oil temperature of the hydraulic station are displayed on the DCS, and the DCS is equipped with low oil pressure, high oil temperature, low oil level alarm or interlocking hydraulic oil station.
The TDC top dead center sensor is in the Hydrocom system, and the TDC sensor (TOPDEADCENTERSENSOR) transfers the instantaneous position of the piston in the cylinder. In order for the TDC sensor to pick up the signal, it is necessary to drill a cylindrical hole of about 10 mm in diameter and 10 mm in depth in the direction perpendicular to the sensor on the compressor flywheel. The TDC signal is compared with the signals of the first and second controllers transmitted by the DCS through the CIU in the electrical room of the hydraulic actuator to control the opening and closing time of the intake valve.
DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A flow chart of a new hydrogen compressor K1601A is a flow chart of a new hydrogen compressor K1601A. When the CIU system is normal, the DCS configures the HA, and the HA completes the control task of opening or closing the intake valve.
Since the new hydrogen compressor K1601A/B shares a control valve 16PV6027 for the outlet return, the control of the new hydrogen compressor K1601A can still be adjusted according to the control scheme of K1601B in the event of a CIU failure, but it is not possible to achieve 0-100 at this time. % load adjustment, but work under 100% load, the excess gas is compressed by the compressor and then stepped back through the 16PV6027 to return to the inlet.
Conclusion Although the device has not been driven yet, according to the working principle of the HYDROCOM system, after using the HYDROCOM system, it will certainly have a good effect on reducing the energy consumption of the hydrogenation unit. Moreover, since the pressure control of the reaction system is optimized, its control will be relatively stable, and it will play a positive role in the safe long-term operation of high-voltage equipment.
