By adopting the program control, the utility model can carry out stochastic pressure adjustments; the utility model not only can supply constant pressure, but also can change the pressure following time parameters, and not only can work independently by becoming to a small system by itself, but also can be used as a sub system which is coordinated and controlled uniformly by the process control system of a laboratory. Besides, the utility model has the advantages of simple structure, reliable work, convenient use, and high precision.
Description
The utility model relates to a kind of numerical control supplied with constant voltage device of geology high-potting, and it is applicable to the explore test place of oil, geology, belongs to the equipment technology field of electromechanical integration.
In oil, mine, geologic prospecting, often need take out core from the depths, stratum, carry out various analysis of experimentss, confirm tectonic structure and mineral reserve reserves and distribution with research.For this reason, put into geology high pressure property testing laboratory to core, and the hyperbaric environment of simulation generation depths, stratum is carried out various physics and chemistry tests to core.Traditional high pressure property research technique is very expensive, and equipment is numerous and jumbled, and control device is also very loaded down with trivial details, is difficult in the exploration rig-site utilization and promotes.
The purpose of this utility model is to utilize contemporary high and new technology, and a kind of digital control high voltage constant voltage source device of electromechanical integration is provided, and is used for supplying with in high pressure property testing laboratory the constant high-voltage power supply equipment of test.
Structure of the present utility model as shown in Figure 1, it includes plunger 2, high pressure cylinder 3, feed liquor valve 4, feed tube 41, tapping valve 5, discharging tube 51, pressure transducer 6, the plunger 2 that is characterized in oil cylinder is contained on the output shaft of digitally controlled linear displacement manipulator 1, and by its passing, the delivery outlet of this oil cylinder is through feed liquor valve 4, feed tube 41 is connected with high pressure cylinder 3, high pressure cylinder is again by tapping valve 5, discharging tube 51, be connected with the supply opening of high-pressure test device 8, at high pressure cylinder standard industrial control 7 is arranged nearby, in this interface, be inserted with respectively and digitally controlled linear displacement controller 1, the pressure transducer 6 that measures high pressure cylinder hydraulic pressure is connected and to its adaptation module of controlling, standard industrial control 7 by the standard traffic serial line interface with can test the shared central control computer of measuring and controlling equipment 9 with other and link to each other.
The utility model is to utilize contemporary advanced standard electromechanical integration common apparatus, is equipped with necessary special-purpose attachment device again, and traditional geology high-pressure test device is undergone technological transformation, and makes it to become an exemplary device of the constant voltage high-voltage power supply of supplying with the test use.Digitally controlled linear displacement manipulator (Chinese patent application number: 91225364.9 wherein, first trial is qualified), the numerical control needle valve (Chinese patent application number: CN91232063.X) and the standard industrial interface interface (China Patent No.: CN90217927) waiting all is the electromechanical integration basic components that utilize contemporary new and high technology to succeed in developing, and all network continues in fields such as scientific research, design, production, engineering multinomial economic results in society such as performance it is energy-conservation, efficient, high-quality.The utility model then be melt machinery with electronics be the new expansion of modern project technology in testing equipment of one, owing to adopt programmed control, can carry out the stochastic and dynamic process control, thereby its output pressure can be steady state value, also can be time dependent dynamic variable; It can have mini system of one's own and work alone, and also can become the subsystem by testing laboratory's Process Control System united and coordinating domination.Device itself is simple in structure, reliable operation, easy to operate, precision is high, can improve operating environment and testing laboratory's quality of high pressure geological test chamber greatly.
The course of work of the present utility model is such: before the test, earlier tapping valve 5 is closed, feed liquor valve 4 is opened.Move behind the digitally controlled linear displacement manipulator 1, make and be filled hydraulic oil (also can adopt other accommodating pressure-transmitting liquid) in the oil cylinder.Feed liquor valve 4 in the utility model and tapping valve 5 can use common manual needle-valve, also can adopt numerical control needle valve (Chinese patent application number: 91232063.X).Use the latter in the adaptation module of other measuring and controlling equipments is inserted the control interface, to be connected as a single entity the control adapter module of this needle valve, aperture to needle-valve automatically adjusts, and utilize measurement parameter to carry out FEEDBACK CONTROL, obtain high control precision and response speed faster.The volume of high pressure cylinder 3 should satisfy the needs of a high-potting process at least.Just open tapping valve after preliminary work is ready, behind the unified instruction issuing of central control computer, the numerical-control motor of digitally controlled linear displacement manipulator is begun slowly to move to advance by the digital command that interface case control adapter module is sent here with regard to accepting, and its shift length can reach very high precision.Be contained in the also displacement feeding forward thereupon of plunger 2 on its output shaft, hydraulic pressure in the high pressure cylinder is risen thereupon, after the dynamic change of its pressure is then gathered by pressure transducer 6, behind the interface case, send into and carry out data processing in the computing machine 9, reach the dynamic setting value of experimentation when hydraulic pressure after, computing machine will make the supply frequency of numerical control device reduce, and the linear displacement manipulator velocity of displacement slows down, so that the pressure of test unit remains on the constant high pressure state, or within the required dynamic change state.The displacement of digitally controlled linear displacement manipulator, the needle-valve open degree of numerical control needle valve and the hydraulic pressure of high pressure cylinder relation can be worked out the control corresponding handling procedure after summing up its quantitative relation after the test of many times, also can adopt senior control strategy such as PID to program.Its control program is determined by test specification, the programmer should be according to the pressure demand of test specification, the mathematical model relation program of weaving in the utility model between each parameter and the test pressure is put into control computer, send into adaptation module in the interface by the standard serial communication interface, take this to control the utility model and synchronous working with whole test device cooperation.
Standard industrial control of the present utility model can be selected the I/OK32 of U.S. ME company (MECHATRONIC EQUIPMENTINC.) or the PB16AH of U.S. OPTO22 company for use, adaptation module can be selected the LC4 controller of U.S. OPTO22 company for use, also can select the PCS-1 industrial process workstation of ME company for use, can also select common PC microcomputer for use.
