Description
Technical field
The present invention relates to a kind of tester, especially a kind of detonator delay time tester, belongs to detonator technical field of measurement and test.
Background technology
At present, along with the development of industrial technology, delay detonator obtains and applies more and more widely in engineering explosion, application particularly in the open in the digging process of ore deposit, serve beneficial effect, delay detonator is at reduction concussion of blasting, reduce oversized fragment rate, reduce the aspects such as blasting flyrock and serve key effect, delay detonator is divided into delay electric detonator, delay detonating detonator and electric detonator, and the defer time of electric detonator is set by detonator built-in chip and computer system, its defer time error is less, more application is obtained in the engineering that some defer time precision prescribeies are higher, delay detonator can be divided into millisecond delay cap by the length of defer time, half second-delay detonator and second-delay detonator, such as modal, according to No. 8 flange shell detonators of GB19417-2003 regulation, its Millisecond Nonel Tube Detonator is divided into 20 sections other, defer time is 0 ~ 2000ms, at some, local to adopt more be 1 to 15 section, defer time is 0 ~ 880ms, within half second, Nonel detonator is divided into 10 sections other, defer time is 0 ~ 5.5s, second, Nonel detonator was also divided into 10 sections other, defer time is 0 ~ 9.0s, half second Nonel detonator and second Nonel detonator be generally used in compared with great explosion engineering and require in the blasting engineering of defer time more than millisecond rank, current use is millisecond delay cap comparatively widely.
Widely using of delay detonator, the instrument testing delay detonator defer time is arisen at the historic moment, the test detonator delay time is significant, test at college teaching, manufacturer's detonator delay time performance detects, the different batches newly entered in blasting engineering, detonator delay time tester all will be used in the important process such as the delay detonator defer time detection of different model, especially corresponding instrument must be adopted to carry out defer time performance test and certification before detonator dispatches from the factory He before explosive applications, therefore, for detecting the test accuracy of the tester of detonator delay time, the advance of performance reliability and instrument all directly affects the accuracy of detonator delay timing, at present, the more detonator delay time test instrument of domestic use mainly contains WYS-1 type detonator delay time tester, the DC9801 type intelligence detonator electric parameter tester etc. of WLD-1 type detonator electric parameter tester and Institutes Of Technology Of Nanjing's development, these instruments are designed and developed early than before " commercial electric detonator " (GB8031-2005) standard revision, now can not meet the test job of existing delay electric detonator defer time.
At present, detonator delay time tester is just towards more accurate, safer, easy to operate, the future development that cost is lower, in this Ye Shi China " industrial explosive materials industry " 12 " development plan ", emphasis is supported, the work of existing detonator delay time test generally comprises detonator delay time tester, test detonator, the compositions such as explosion-proof tank, although the defer time of detonator also can be tested out preferably, these may because operate miss or other faults, test detonator is caused to meet accident, these all directly affect the security of the lives and property of tester, the sound even testing blasting cap detonation generation also can produce larger harm to tester, more even some explosion-proof tank structural design is unreasonable, test box is caused greatly to reduce service life, add testing cost.
A kind of testing arrangement for Detonator delay element defer time is devised in Chinese patent (application number is 2011103165267) " a kind of testing delay of detonator delay element method and device ", its method of testing and device are comparatively complicated and loaded down with trivial details, and do not meet the requirement to civil explosive material development in China's " industrial explosive materials industry " 12 " development plan ".The safety interlocking that a kind of Nonel detonator defer time measures is devised in Chinese patent (patent No. is ZL201110179866X) " safety interlocking for detonator delay time detecting ", it is only between blasting cap detonation case and detonator delay time tester, be provided with a baffle plate, this baffle plate is with automatic linkage device, its shortcoming is that test system structure is comparatively complicated, system dimension is larger, operate loaded down with trivial details, production cost is changed high, at present, very ripe about the circuit design of detonator delay time tester both at home and abroad, technique is relative specification also, the defer time measured is also comparatively accurate, but existing detonator delay time tester still also exists poor stability, the problem such as complex operation and high expensive, these are all problem demanding prompt solutions.
