At present, existing teaching about constant pressure water supply system also rests on written basically.The student can only be merely with imagining the relevant knowledge of learning constant pressure water supply, lack a kind of intuitively, easily experimental facilities come clear, reflect and the running of relevant constant pressure water supply system can't improve the grasp degree of student accurately for constant pressure water supply system.
Summary of the invention
The purpose of this utility model is to provide a kind of simulation constant pressure water supply system experimental facilities of operation conditions that can visual and accurate reflection constant pressure water supply system.
The utility model comprises simulation water supply used water device, the pressure acquisition device, electric apparatus control apparatus and computer monitor software are formed, wherein said simulation water supply used water device comprises the feed tank as the water source, the water pump that is connected by pipeline with described feed tank, be connected by pipeline with described water pump and by described water pump with the high-pressure tank of water by the feed tank suction, the pipeline that connects described high-pressure tank is provided with the electromagnetic valve that can control the described high-pressure tank water yield, link to each other by pipeline with described high-pressure tank and by the header tank of described solenoid control discharge, described header tank is connected by pipeline with described feed tank; Described pressure acquisition device comprises that the pressure sensor that can gather the hydraulic pressure size and the analog signal conversion that described pressure sensor can be collected are the A/D converter of data signal; Described electric apparatus control apparatus comprises frequency converter, can control the relay group of pump switch and control the PLC of described relay group work; Described computer monitor software comprises the real-time monitoring module that can be used for monitoring described constant pressure water supply system operation and can operate the intelligent scoring module that the situation of this experimental facilities is made an appraisal to the student.
The utility model is owing to simulate the workflow of the constant pressure water supply system in the reality fully, so can reflect the running status of constant pressure water supply system accurately, carry out simulation teching for real constant pressure water supply system, make the student visual and understandable when study, the running of understanding and grasping whole system and principle that can be more deep improve the effect of student's study greatly.Intelligent scoring module in the utility model computer monitor software can be monitored student's PLC program, and the PLC program that requires the student to write can realize examining the control function of requirement, the student is had higher requirement, fully tempered students'comprehensive.In addition, device terminal in the utility model is all unified to be connected on the control panel, and the operator only need pass through the superposition line, and these components and parts and frequency converter, PLC equal controller are coupled together and can experimentize.Change external control device or change control program just can the whole experiment of conversion be formed structure and content.Convenient, flexible, various also is characteristics of the present utility model.
The utility model is described in further detail below in conjunction with accompanying drawing:
Description of drawings
Fig. 1 is the utility model simulation water supply used water device schematic diagram;
Fig. 2 is the utility model electric apparatus control apparatus structural representation;
The specific embodiment
Extremely shown in Figure 2 as Fig. 1, the utility model comprises simulation water supply used water device 1, pressure acquisition device 2, electric apparatus control apparatus 3 and computer monitor software are formed, wherein said simulation water supply used water device 1 comprises the feed tank 11 as the water source, the water pump 12 that is connected by pipeline with described feed tank 11, be connected by pipeline with described water pump 12 and by described water pump 11 with the high-pressure tank 13 of water by feed tank 11 suction, the pipeline that connects described high-pressure tank 13 is provided with the electromagnetic valve 14 that can control described high-pressure tank 13 water yields, link to each other by pipeline with described high-pressure tank 13 and by the header tank 15 of described electromagnetic valve 14 controlled water flow amounts, described header tank 15 and described feed tank 11 are connected by pipeline; Described pressure acquisition device 2 comprises that the pressure sensor that can gather the hydraulic pressure size and the analog signal conversion that described pressure sensor can be collected are the A/D converter of data signal; Described electric apparatus control apparatus 3 comprises frequency converter 31, can control the relay group 32 of pump switch and controls the PLC that described relay group 32 is worked; Described computer monitor software comprises the real-time monitoring module that can be used for monitoring described constant pressure water supply system operation and can operate the intelligent scoring module that the situation of this experimental facilities is made an appraisal to the student.
In the practice, working method of the present utility model be PLC as the pressure acquisition parts, convert force value to digital quantity, more whether at areas of permanent pressure, if hypotony just reduces the frequency of water pump or reduces water pump quantity, otherwise then increases frequency or quantity.Have only a water pump in the experiment as converting operation, other two can only power frequency operation (below, be called for short variable frequency pump and general pump).If the running frequency of variable frequency pump will surpass 45Hz, just other general pump is started, the frequency of variable frequency pump is operation from low to high again, if frequency surpasses 45Hz again, then start second main frequency water pump, the frequency of variable frequency pump is operation from low to high again, up to switching to power frequency.When hypertonia, job step is with above-mentioned opposite.
