Detailed Description

The entire system of the process control trainer is divided into: the upper control layer system, experimental object layer,detection sensor, transmitter, perform device, PC control software four parts. System features: theentire system placed on a movable table test bench, test apparatus compact and small footprint.DLGK-373-based process control system experiment projectExperiment projects:Consists understanding experiment of the process control system:(1) Process control and detection device hardware structure composed understanding, thecomposition of the control program and control system connection experiment.(2) Smart regulation instruments, smart transmission instruments such as smart meter operationand parameter settings.(3) The sensor calibration (zero and span adjustments migration)Object properties testing laboratories(1) Single-tank water level mathematical model test experiment(2) Dual tank water level mathematical model test experiment(3) Boiler liner water temperature characteristic test experimentsSingle-loop control system experimentSingle-tank water level setpoint control experimentsDual tank water level setpoint control experimentsBoiler liner water temperature setpoint control experimentsSingle-loop flow setpoint control experimentsBoiler liner pressure setpoint control experimentsCascade Control System ExperimentTank level cascade control experimentsTANK boiler water temperature and circulating water flow cascade control experimentsTank level with the inlet flow cascade control experimentsRatio Control System ExperimentFlow ratio control system experimentConstant pressure water supply experimentIndustry control configuration software configuration control experimentsAll experiments were performed including database configuration, graphics, animation, report,curve, alarm configuration, equipment, communication configuration, algorithms, and otherexperimental configurationⅥ Technical parameterPower supply: single-phase three-wire 220V ± 5% 50Hz/60HzDimensions: Bench 1510 × 720 × 1810mmMachine Capacity: <5KVA \ Control signal: current 4~20mAⅦ Security protection systemProgrammed heating boiler protection system1, the boiler heating water level protection liner plus the apparatus does not reach a certain heightlevel, the control system can not control thyristor regulator work.2, electric heating tube power control switch with key switch, do not experiment, placed byteachers to protect key, to avoid misuse of unrelated persons.Power Protection Measures1, plus a current-leakage protection.2, two-phase power plus fuse to prevent disconnection.Power start-stop control mode;Start and Stop buttons to control the contactor to control the start and stop of the power.leakage protection devices and safety and security commitments;various power and a variety of instruments reliable protectionVarious power and a variety of instruments using strong electric switch control, students do notown wiring, there is no problem of weak electric hybrid plug.Experimental strong electrical wiring plug in a closed structure to prevent electric shock accidents.  http://www.dolangeducation.com/pcs-training-series/
