Abstract
The utility model relates to a method for realizing automatic pressure detection of a mechanical instrument by adopting arbitrary pressure change rate. The technology has the core of an automatic pressure controller independently developed by the company, and an automatic control module with the arbitrary pressure change rate is arranged inside the automatic pressure controller, consists of a pressure sensor and a change rate control circuit and can generate the arbitrary pressure change rate. The automatic pressure controller has the unique pressure change rate automatic control function and can automatically adapt to various volumes. In the method, the pressure change rate required by the control can be arbitrarily set on the automatic pressure controller according to the detection requirements of the mechanical instrument, then, the automatic pressure controller can control the pressure at the uniform speed according to the pressure change rate to the pressure detection point to be stabilized on the pressure detection point without overshoot, and the control stability can reach +/- 0.003 percent FS. Meanwhile, through the remote command control of a host machine on the automatic pressure controller, the automatic setting and the automatic control of each pressure detection point can be realized, so the automatic pressure control is realized, the problem of difficult and complicated manual detection of the mechanical pressure instrument is solved, and the goal of automatic detection is realized.
Description
Technical field
The utility model relates to a kind of automatic pressure controller, its any pressure change rate control realizes the automatic pressure calibrating of mechanical pressure gauge, its technological core is the automatic pressure controller of independent research, its built-in any pressure change rate self-actuated controller module, any rate of change that it can be set according to the user automatically carries out pressure control, by the pressure in the supporting pressure seal case is carried out pressure control accurately by rate of change, thereby realize the manometric automatic pressure calibrating of pressure seal inner box-machine tool.
Background technology
At present the mechanical pressure gauge calibrating mode of generally using is by several groups of needle-valves or solenoid control positive pressure pump and vacuum pump the mechanical pressure in the seal box to be examined and determine.These modes are manually control substantially, and some mechanical pressure gauge requires pressure can at the uniform velocity change to pressure calibrating point when pressure is examined and determine, and manually control is difficult to realize.Simultaneously, the leakage of seal box internal pressure and variation of temperature cause the seal box internal pressure can't be stabilized on the pressure calibrating point.Therefore, the working pressure self-actuated controller realizes that the at the uniform velocity stable control of pressure is very necessary.
The utility model content
This method adopts any pressure change rate control to realize the automatic pressure calibrating of machinery instrument.The core of this technology is the automatic pressure controller of my company's independent research, and inside has any pressure change rate automatic control module, and this module is made up of pressure transducer and rate-of-change control circuit, can produce pressure change rate arbitrarily.The automatic control function of pressure change rate that it contains original creation can adapt to various volume automatically.This method can be set the needed pressure change rate of control arbitrarily by the calibrating requirement of machinery instrument on automatic pressure controller, then automatic pressure controller can by this pressure change rate at the uniform velocity controlled pressure to pressure calibrating point, be stabilized in not overshoot in the pressure calibrating, control stiffness can reach ± 0.003%FS.Simultaneously, by the remote command control of host computer, can realize the automatic setting of each pressure calibrating point to automatic pressure controller, automatically control, thereby realized the automatic control of pressure, solved the mechanical pressure instrument and manually examined and determine difficult complicated problems, thereby reached the purpose of automatic Verification.
Description of drawings
Fig. 1 is system's connection layout that any pressure change rate of automatic pressure controller described in the utility model is realized the mechanical pressure gauge calibrating.
Embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
As shown in the figure, this system is by automatic pressure controller, the pressure criteria device, the pressure seal case, host computer, positive pressure pump, vacuum pump is formed, to automatic pressure controller pressure calibrating point and pressure change rate are set by host computer, automatic pressure controller is just controlled automatically by the pressure change rate of setting then, in the control procedure, automatic pressure controller calculates actual pressure and pressure change rate in front sealed box by the normal pressure value of real-time collection pressure criteria device, compare with setting value, adjust pressure control more in real time pressure change rate is stabilized on the value of setting, thereby at the uniform velocity control to pressure calibrating point.After stable, write down the indicating value of tested instrument after, host computer automatic setting automatic pressure controller is controlled next pressure calibrating point.Thereby reach the purpose of automatic Verification.
