The pneumatic brake valve test bench is composed of a stepping motor, a speed reducer, a force sensor, an angle sensor, a displacement sensor, an on-beam sensor, a stage body, and a jig. The electrical system consists of a control system and an acquisition system. The control system mainly uses PCL-720+ digital I/O cards and PCI-1721 analog output cards. The acquisition system uses PCI-1747U data acquisition cards.
PCI-1721 Analog Output Card Provides 4 Analog Output Channels of High-Speed ​​PCI Bus Cards with 5MHz Maximum Digital Update Rate, Auto-Calibration, and a 12-Bit Dual-Buffer DAC for Each Analog Output Channel with Internal/External Triggered real-time waveform output with flexible input types and range settings.
The analog output signal provided by the PCI-1721 analog output card is used to control the stepper motor, and then through the reducer to control the size of the pedal force. The corresponding display instrument and control switch are mounted on the panel. The PCL-720+ digital I/O card controls the opening of the solenoid valve and the control of other protection units. At the same time, the PCI-1721 analog output card is also used to control the size of the electromagnetic proportional valve to control the pressure exerted by the test sample. size.
The acquisition system mainly uses the analog input signal provided by the PCI-1747U data acquisition card to collect the values ​​of displacement sensors, angle sensors, force sensors, and pressure sensors.
SDRFD filter consists of one-piece housings with a bolt-on cover plates. The two housings are connected by a ball change-over valve. There are clogging indicators on both sides.
