The course of work of the present invention is sketched with reference to Fig. 1, Fig. 2：
The course of work of the present invention is introduced so that gas cylinder hydraulic pressure detects comprehensive practical training project as an example：Carrying out gas cylinder hydraulic pressure detection
Before, should first be ready work, preparation at least include by all motor and water pump A 2 in the present apparatus, motor and
The components such as water pump B 29, valve, pressure gauge, liquid level sensor 20, cooling-water temperature sensor 19, water temperature heating 18, electronic scale 17
With corresponding controller（Such as controller PLC, frequency converter VVVF and programming monitoring PC ends and touch-screen HMI）Equipment is connected
Connect, be connected between controller by Ethernet switch or serial communication RS485 bus ports, the 121 of controller PLC is ether
Network interface, 122 are RS485 serial bus interfaces, by PC ends by associated control procedures, parameter, configuration interface is downloaded to compile
In range controller PLC, frequency converter VVVF and touch-screen HMI（Frequency converter VVVF parameter setting can also be set by panel）；
Then open hand-operated valve A 5 and city's water is incorporated into storage tank 1 by hand-operated valve B 21, treat that the water 31 in storage tank 1 adds to water storage
Case 1 80% or so when, close hand-operated valve A 5 and hand-operated valve B 21（If having during experimental real-training in storage tank 1 for experimental real-training
The water that mesh needs need not then operate this step）；All hand-operated valves close in advance under, pass through PC ends or touch-screen HMI or control
The starting button that water filling is carried out to internal box 13 on control equipment, the magnetic valve A 4 controlled by controller PLC program open and
Motor and water pump A 2 bring into operation, rapidly to the water filling of internal box 13, when liquid level sensor 20 is detected in internal box 13
Water is full, then closes magnetic valve A 4 and stop motor and water pump A 2 operation, the water temperature entered as noted does not reach gas cylinder inspection
Survey condition, then system sends police instruction, while starting water temperature heating 18 and stepping or the servomotor 11 of stirring
Dynamic to be stirred, the water temperature in the holding internal box 13 of water temperature heating 18 meets water temperature in testing conditions, or storage tank 1 and met
Testing conditions, then controller PLC is by programme-control opening magnetic valve C 7 and motor and water pump B 29 is worked, storage tank 1
In water 31 start to be rapidly injected outer case 14, treat that the water in outer case 14 is filled（Water overflows from drainpipe A 15, appearance of weighing
The reclaimed water of device 16 increased again）When close magnetic valve C 7 and stop motor and water pump B 29, operator passes through PC ends or touch
Peeling function button on screen HMI or electronic scale 17 makes electronic scale 17 realize peeling function, or is set to by program to hold automatically
Row peeling function；The gas cylinder hydraulic pressure detection that operator is pressed on PC ends or touch-screen HMI starts on button or control device
Dynamic button starts to carry out pressurization detection to internal box 13, and now the stepping for stirring or servomotor 11 are stopped,

Hour hands are rotated, to show that hydraulic pressure is gradually increasing in internal box 13, when hydraulic pressure gradually rises to detect pressure arranges value in internal box 13
90% or so, motor and the slower water fillings into internal box 13 of water pump A 2, when hydraulic pressure reaches detection pressure in internal box 13
During arranges value, close magnetic valve A 4 and stop motor and water pump A 2 work, in the process, the hydraulic pressure of internal box 13 is not because
Break and raise and expand internal box 13, so as to extrude outer case 14, the reclaimed water of outer case 14 is overflowed and is flowed by drainpipe A 15
Enter in weighing container 16, then gas cylinder detection process enters packing stage, after pressurize 2 minutes, gas cylinder detection process enters release
Stage, magnetic valve B 6 is opened, and release is carried out to the water under high pressure in internal box 13, and water under high pressure flows into storage tank 1 by relief tube 28
In, internal box 13 shrinks because of release, causes that part water suck-back enters in outer case 14 in weighing container 16 again, after the completion of release（Mould
The display data of pseudopressure table 8 is 0, and the pointer of electro connecting pressure gauge 9 goes back to original position）, the remaining water in weighing container 16 is gas cylinder
The remaining displacement of hydraulic pressure detection；The analog signal that displacement is passed through itself by electronic scale 17 in real time in gas cylinder hydraulic pressure detection process
Line or communication data line send controller PLC to, controller PLC by data processing by hydraulic pressure-time graph, displacement-
Real-time hydraulic pressure value, displacement, maximum displacement, remaining displacement lead in time graph, displacement-hydraulic curve, internal box 13
Cross touch-screen HMI or PC ends to show, if simulated pressure table 8 is damaged in hydraulic pressure detection process or controller PLC matches
Analog quantity and digital quantity modular converter（Module for receiving sensor output signal）Damage or data communication failure, cause
The hydraulic pressure of internal box 13 is set to exceed system detectio arranges value, now the upper limit normally opened contact of electro connecting pressure gauge 9 is closed, to controller
PLC sends stopping detection instruction, and now detection process stops, and when occurring abnormal conditions in detection process, operator can pass through
Press on PC ends or touch-screen HMI gas cylinder hydraulic pressure detection stop key or control device on stop button, can also stop inspection
Survey process；After release terminates, water temperature heating 18 stops that internal box 13 will be shown on heating, touch-screen HMI or PC ends（Simulation
Gas cylinder）The full deformation rate of volume and rate of residual and the information such as whether hydraulic pressure testing result qualified, the detection of gas cylinder hydraulic pressure terminates
Afterwards, operator presses the drain button on gas cylinder hydraulic pressure detection draining button or the control device on PC ends or touch-screen HMI, electricity
Magnet valve D 23（Opening degree is adjusted to maximum）, magnetic valve E 26 open, the water in internal box 13, outer case 14 passes through drainpipe
Its internal water is discharged in storage tank 1 by C 22, drainpipe B 25, when the detection data of liquid level sensor 20 are 0 and one section of extension
After time, magnetic valve D 23, magnetic valve E 26 are closed, and now drainage procedure terminates；Hand-operated valve B 21 and hand-operated valve C 24 are used for
Water in manual internal box 13, outer case 14 is discharged in storage tank 1 by drainpipe C 22, drainpipe B 25, the He of hand-operated valve 32
Drainpipe D 33 is used for the hand-held evacuation of water 31 in storage tank 1；The opening degrees of magnetic valve D 23 can adjust for internal box 13
In the experimental real-training project such as constant pressure water supply PID control or permanent liquid level PID control；Roller 34 below device is used for the dress
The movement put.
Motor 1 in motor and water pump A 2 is stepping or servomotor, if stepping motor, then driver
