Description
Technical field
The utility model relates to a kind of for the experimental bench system to the production of different model water pump and the design data checking of water pump.
Background technique
Water pump is the critical component of power plants generating electricity unit, and the quality of pump performance and working condition will be directly connected to performance and the working condition of whole unit.Water pump alone relatively simple for structure, but liquid moves very complicated in pump chamber, therefore pump test just becomes the Main Basis checking the Design and manufacture of pump whether up to standard, pump test comprises type approval test and delivery test, only have and adopt advanced measuring technology, accurate method of measurement and instrument to test water pump, obtain accurate test data, by analytical test data, the requirement whether pump working situation meets work on the spot could be evaluated, therefore combined test to the design of water pump, manufacture most important.
Generally we have come primarily of button common old-fashioned pump test system, the experience of workman is mainly leaned on to complete the regulable control of valve in the accurate control of the flow in process of test, test data is completely by manually copying, carry out the pressure of water pump, flow, the testing propertys such as temperature, this testing precision is low, real-time and poor reliability, and location dispersion, whole measurement signal does not have integrated management, instrumentation is old-fashioned instrument entirely, as: with mercury manometer, the measuring pressures such as spring pressure gage, with measuring flows such as turbine flowmeters, with ammeter, parameters of electric power measured by voltmeters etc.Test instrumentation is bulky, and cost is high, and reliability is low, and experimenter is many, and workload is large, and test efficiency is low.
Model utility content
Technical problem to be solved in the utility model provides for above-mentioned prior art that a kind of testing efficiency is high, operating cost is low, can realize the test installation of pump system of Automated condtrol.
The technical scheme in the invention for solving the above technical problem is: a kind of test installation of pump system, comprise the water storage box for supplying water to tested water pump, switch cubicle, transformer, frequency variator, AC motor, torsionmeter, wherein said switch cubicle, transformer, frequency variator and AC motor step by step power are connected, described AC motor is connected by shaft joint with torsionmeter, described torsionmeter is connected to tested water pump further by shaft joint, and gauge sensor and DCS control system, described gauge sensor is connected to described frequency variator respectively, AC motor, torsionmeter, entering of tested water pump and water storage box, outlet pipe, for detecting the test parameters of tested water pump, described DCS control system is connected with described gauge sensor, for collecting, transmit and process the data that described gauge sensor detects.
During concrete test, the high-tension electricity that electric substation transports to frequency variator, makes transducer drive AC motor by switch cubicle direct power transmission after transformer pressure-reducing, when needs are under different rotating speeds during test water pump performance, only need control AC motor by frequency variator can realize, very easy, effective.In tested water pump operation process, gauge sensor detects the test parameters of relevant water pump as parameters such as flow, pressure, temperature, voltage, electric current, moments of torsion, and these data are transferred to DCS control system, shown in real time by DCS control system and be recorded in upper-position unit, after partial arithmetic process being carried out to data by upper-position unit after off-test, being printed as the form that user needs.
Compared with prior art, the utility model has the advantage of: the test installation of pump system provided achieves the collection of parameter in pump test process, transmission and process, drastically increases the automaticity of pump test, test accuracy and test efficiency.Adopt the power source of VFC mode, the control of rotating speed can be realized quickly and accurately, in real time adjustment, real-time testing.
Accompanying drawing explanation
Fig. 1 is the structural representation of test installation of pump system in the utility model embodiment.
Embodiment
Below in conjunction with accompanying drawing, embodiment is described in further detail the utility model.
As shown in Figure 1, test installation of pump system in the present embodiment, comprise the water storage box 7 for supplying water to tested water pump 6, switch cubicle 1, transformer 2, frequency variator 3, AC motor 4, torsionmeter 5, wherein said switch cubicle 1, transformer 2, frequency variator 3 and AC motor 4 step by step power are connected, described AC motor 4 is connected by shaft joint 10 with torsionmeter 5, described torsionmeter 5 is connected to tested water pump 6 further by another shaft joint 10, and gauge sensor 8 and DCS control system 9, described gauge sensor 8 is connected to described frequency variator 3 respectively, AC motor 4, torsionmeter 5, entering of tested water pump 6 and water storage box 7, outlet pipe, for detecting the test parameters of tested water pump 6, described DCS control system 9 is connected with described gauge sensor 8, for collecting, the data that transmission and processing instrument table sensor 8 detect.
During pump test, frequency variator 3 is directly delivered to after the high-tension electricity step-down that electric substation transports by switch cubicle 1 and transformer 2, frequency variator 3 Received signal strength drives AC motor 4 to run with certain rotating speed, when needing to test water pump 6 performance under different rotating speeds, only need control AC motor 4 by frequency variator 3 can realize.In tested water pump 6 running, gauge sensor 8 real-time sampling tests the relevant parameter of tested water pump 6 as the data of flow, pressure, temperature, voltage, electric current, moment of torsion etc., and these data are transferred to DCS control system 9, shown in real time by DCS control system 9 and be recorded in upper-position unit, after partial arithmetic process being carried out to data by upper-position unit after off-test, being printed as the form that user needs.
The test installation of pump system of said structure achieves the collection of parameter in pump test process, transmission and process, drastically increases the automaticity of pump test, test accuracy and test efficiency.
