By the adoption of the design that the inductor outer shell is made of the explosion-proof material, the pressure testing device can perform precise tests on kinds of pressure including overpressure and impact wave pressure, and precision of the pressure tests is ensured through reasonable combination of the piezoelectric type pressure sensor, the charge amplifier, the electric potential display instrument, the pressure display instrument and other instruments.
Description
Technical field
The invention belongs to testing apparatus, relate to a kind of pressure test device.
Background technology
At present, the research of pressure test device has been entered into deep structure research both at home and abroad, just simple pressure test, can calculate acquisition by theory, can test acquisition by exact instrument, also can pass through rough acquisition by General Instrument, but with regard to current technology, theoretical calculating is too loaded down with trivial details, calculated amount is larger, the power that consumes again consuming time, and may not necessarily obtain correct result, test for exact instrument, its cost is higher, general these exact instrument are only in National Key Laboratory, in some large enterprises, have, high for common researcher and medium and small sized enterprises' use cost, neither desirable approach for the walk through test of General Instrument, the possibility of result error that it tests out is larger, for research and use, exist larger discrepancy.
At present, the problem of relevant pressure test technology, there is no the special treatise of system both at home and abroad, but due to the fast development of piezo-electric pressure sensor in recent years, the high-performance sensors of various ranges emerges in an endless stream, add multichannel data recording and storage instrument, make pressure test, particularly superpressure has not been to be expected untouchable difficulty, and the development of computing machine and interfacing thereof in recent years, make pressure, particularly the data processing of superpressure test becomes more accurate, convenient, fast.
For pressure test device, particularly to the test of superpressure, can test by data analysis and the treatment technology of number of ways, current operable technology has the instruments such as piezoelectric pressure indicator, charge amplifier, current potential display instrument and pressure display instrument.
The piezoelectric pressure indicator that piezoelectric pressure indicator selects KISTLE company to produce, this piezoelectric pressure indicator response is fast, highly sensitive, and signal to noise ratio (S/N ratio) is high, is applicable to freedom of the air field blast dynamic pressure measurement.
Charge amplifier also can select KISTLE company to produce, and it is the low-noise charge amplifier that a kind of output voltage is directly proportional to input charge amount, and charge amplifier is one and has the degenerative high-gain amplifier of the degree of depth.It and piezo-type sensor connect, and pressure signal is converted to electric signal.It is little that it has noise phase error little, reliable and stable, between many, in test, outputting multiplex signals is very beneficial simultaneously; In addition, it is subject to input to connect long cable affects very littlely on measuring accuracy, be a significant benefit to test.
Summary of the invention
The object of the present invention is to provide a kind of pressure test device, it tests difficult bottleneck by the use of shell explosion-proof lamp being intended to solve prior art to high pressure or even superpressure, simultaneously by making pressure test more accurate to being used in combination of existing instrument.
The object of the invention is to be achieved by the following technical programs, a kind of pressure test device, its structure comprises pressure sensitive sheet, inductor shell bearing, induction spring, inductor shell, piezoelectric pressure indicator, charge amplifier, current potential display instrument, pressure display instrument and wire, and described inductor sheathing material is used explosion-proof lamp.
A kind of pressure test device of the present invention in use, first to make each instrument be in the scope of normal use, before test, will assemble together line, then be installed in inductor shell, open the switch of proving installation, when general pressure is tested, can whole proving installation not done to special processing, when test be superpressure or explosion wave superpressure time, its shell that makes that will try one's best to whole proving installation reduces the contact to superpressure, make pressure sensitive sheet contact superpressure as much as possible, can protect whole proving installation like this, can obtain again comparatively accurate test data.
The present invention compared with prior art, has following apparent outstanding substantive distinguishing features and remarkable advantage:
1, the present invention uses the design of explosion-proof lamp by pressure inductor shell, can be well to various pressure, comprise that superpressure and shock wave pressure test accurately.
