Utility model works process is sketched with reference to Fig. 1, Fig. 2：
Utility model works process is introduced so that gas cylinder hydraulic pressure detects comprehensive practical training project as an example：Carrying out gas cylinder
Before hydraulic pressure detection, should first be ready work, preparation comprise at least by all motor and water pump A 2 in the present apparatus,
Motor and water pump B 29, valve, pressure gauge, liquid level sensor 20, cooling-water temperature sensor 19, water temperature heating 18, electronic scale 17
Deng component and corresponding controller（Such as controller PLC, frequency converter VVVF and programming monitoring PC ends and touch-screen HMI）
Equipment is connected, and is connected between controller by Ethernet switch or serial communication RS485 bus ports, controller PLC's
121 it is Ethernet interface, 122 is RS485 serial bus interfaces, by PC end by under associated control procedures, parameter, configuration interface
It is downloaded in programmable controller PLC, frequency converter VVVF and touch-screen HMI（Frequency converter VVVF parameter setting can also pass through face
Plate is set）；Then open hand-operated valve A 5 and city's water is incorporated into storage tank 1 by hand-operated valve B 21, treat the water 31 in storage tank 1
When adding to 80% or so of storage tank 1, hand-operated valve A 5 and hand-operated valve B 21 is closed（If have during experimental real-training in storage tank 1 for real
This step need not then be operated by testing the water of practical training project needs）；All hand-operated valves close in advance under, pass through PC ends or touch-screen
The starting button that water filling is carried out to internal box 13 on HMI or control device, the magnetic valve A controlled by controller PLC program
4 openings and motor and water pump A 2 bring into operation, rapidly to the water filling of internal box 13, when liquid level sensor 20 detects interior case
Water in body 13 is full, then closes magnetic valve A 4 and stop motor and water pump A 2 operation, the water temperature entered as noted is not up to
To gas cylinder testing conditions, then system sends police instruction, while starts stepping or the servo electricity of water temperature heating 18 and stirring
Motivation 11 is started and is stirred, and water temperature heating 18 keeps the water temperature in internal box 13 to meet testing conditions, or the reclaimed water of storage tank 1
Temperature has met testing conditions, then controller PLC opens magnetic valve C 7 by programme-control and makes motor and the works of water pump B 29
Make, the water 31 in storage tank 1 starts to be rapidly injected outer case 14, treats that the water in outer case 14 fills（Water is from drainpipe A 15
Overflow, the reclaimed water of weighing container 16 increased again）When close magnetic valve C 7 and stop motor and water pump B 29, operator is led to
The peeling function button crossed on PC ends or touch-screen HMI or electronic scale 17 makes electronic scale 17 realize peeling function, or passes through program
It is arranged to perform peeling function automatically；The gas cylinder hydraulic pressure detection that operator is pressed on PC ends or touch-screen HMI starts button or control
Starting button on control equipment starts to carry out pressurization detection to internal box 13, now the stepping for stirring or servomotor
11 are stopped, and magnetic valve A 4 opens to be run again with motor and water pump A 2, quickly（Middling speed）Enter into internal box 13
Row water filling, at this moment simulated pressure table 8 show internal box 13 in real time hydraulic pressure value can gradually increase, the finger of electro connecting pressure gauge 9
Pin also can be rotated clockwise gradually, and to show, hydraulic pressure is gradually increasing in internal box 13, when hydraulic pressure gradually rises to examine in internal box 13
90% or so of measuring pressure arranges value, motor and the slower water fillings into internal box 13 of water pump A 2, when hydraulic pressure in internal box 13
When reaching detection pressure arranges value, close magnetic valve A 4 and stop motor and water pump A 2 work, in the process, interior case
The hydraulic pressure of body 13 expands internal box 13 because constantly raising, and so as to extrude outer case 14, the reclaimed water of outer case 14 is overflowed and is passed through
Drainpipe A 15 is flowed into weighing container 16, and then gas cylinder detection process enters packing stage, and after pressurize 2 minutes, gas cylinder detects
Process enters the release stage, and magnetic valve B 6 is opened, and carries out release to the water under high pressure in internal box 13, water under high pressure passes through relief tube
28 flow into storage tank 1, and internal box 13 causes the inside points water suck-back of weighing container 16 to enter in outer case 14 again because release is shunk,
After the completion of release（The display data of simulated pressure table 8 is 0, and the pointer of electro connecting pressure gauge 9 goes back to original position）, it is remaining in weighing container 16
Water detect remaining displacement for gas cylinder hydraulic pressure；Electronic scale 17 in real time passes through displacement certainly in gas cylinder hydraulic pressure detection process
The analog signal line or communication data line of body send controller PLC to, and controller PLC is bent by hydraulic pressure-time by data processing
Real-time hydraulic pressure value in line, displacement-time graph, displacement-hydraulic curve, internal box 13, displacement, maximum displacement,
Remaining displacement is shown by touch-screen HMI or PC ends, if simulated pressure table 8 is damaged or controlled in hydraulic pressure detection process
The analog quantity that device PLC processed matches and digital quantity modular converter（For receiving the module of sensor output signal）Damage or number
According to communication failure, the hydraulic pressure of internal box 13 is caused to exceed system detectio arranges value, now the upper limit normally opened contact of electro connecting pressure gauge 9 closes
Close, stopping detection instruction is sent to controller PLC, now detection process stops, when abnormal conditions occurring in detection process, behaviour
Author can by press the gas cylinder hydraulic pressure on PC ends or touch-screen HMI detection stop key or control device on stop button,
Also detection process can be stopped；After release terminates, water temperature heating 18 stops heating, by case in display on touch-screen HMI or PC ends
Body 13（Simulate gas cylinder）The full deformation rate of volume and the information such as whether rate of residual and hydraulic pressure testing result qualified, gas cylinder hydraulic pressure
After detection terminates, operator presses the row on gas cylinder hydraulic pressure detection draining button or control device on PC ends or touch-screen HMI
Water button, magnetic valve D 23（Opening degree is adjusted to maximum）, magnetic valve E 26 open, the water in internal box 13, outer case 14
Its internal water is discharged in storage tank 1 by drainpipe C 22, drainpipe B 25, is 0 when liquid level sensor 20 detects data
And after extending a period of time, magnetic valve D 23, magnetic valve E 26 are closed, and now drainage procedure terminates；Hand-operated valve B 21 and manually
The water that valve C 24 is used in manual internal box 13, outer case 14 is discharged in storage tank 1 by drainpipe C 22, drainpipe B 25,
Hand-operated valve 32 and drainpipe D 33 are used for the hand-held evacuation of water 31 in storage tank 1；The opening degrees of magnetic valve D 23, which can adjust, to be used for
In the experimental real-training project such as the constant pressure water supply PID control of internal box 13 or permanent liquid level PID control；Roller below device
34 are used for the movement of the device.
Motor 1 in motor and water pump A 2 is stepping or servomotor, if stepping motor, then driver
For driving stepper motor machine；If servomotor, then driver is servomotor driving machine；Motor and water pump B 29 include
Motor 2.
