Electric spark detector, call electric spark leak detector again, full name electric spark is anticorrosive layer detector, electric spark is anticorrosive layer leak detector. This instrument uses high-pressured pulse principle, go up when electric metal matrix namely pinhole of existence of anticorrosive insulation coating, sand holes, the instrument when the anticorrosive blemish such as bleb sends phonate light to call the police, partial intelligence computation instrument records anticorrosive blemish amount at the same time. This instrument is OK to the glassed steel glass reinforced plastics of different ply the coating such as annulus oxygen coal tar pitch and balata liner undertakes quality detects. Instrument of electric spark detector applies extensively at oil gas cropland company of installation of anticorrosive can without lid and conduit, conduit, build project of factory of factory of conduit of company of the grain that bring watch, chemical industry, enamel, mechanical, power plant, dockyard, petrifaction, war industry, bridge to wait for an industry. Instrument of electric spark leak detector detects voltage has: According to anticorrosive layer ply different choice detects suitably voltage, groovy instrument detects voltage has 500V-6KV, 5KV-30KV, 500V-30KV 3 kinds, the low pressure of the high-pressured club that leak detector of type of pressing with a finger matchs to have 5KV-30KV and 500V-6KV is strong two kinds, club of a high pressure realizes number instrument the full span of 500V-30KV. In providing check-up to measure a process, answer to particular material pledges and choose to detect reasonably according to anticorrosive layer ply and object voltage. Leak hunting voltage decides according to following formula: (1) 0. 2mm, 0.
4mm, 0.
6mm, 0.
4~5KV of choice of coal tar pitch of 8mm annulus oxygen detects carry out related voltage or basis. (2) petroleum pitch is anticorrosive the layer is thick 2, 3, 5.
5, 7, 9(mm) correspondence detects voltage is respectively 11, 15, 18, 20, 24(kv) . (3) polyethylene adhesive plaster, when Tc<1mm: V=3294 √ Tc becomes when Tc ≥ 1mm: V=7843 √ Tc, v: Voltage, TC: Anticorrosive layer ply; Check and accept normative standard to carry out by SY4014-92. (4) glassed steel inspects experience to detect certainly voltage, it is 8KV~20KV commonly. (5) 3PE of conduit of general and common fuel burning gas is anticorrosive the layer is commonly used detect voltage is 15KV.
(6) other is anticorrosive material, detect according to designing sectional design the insulation property of voltage or material itself and calm. Author: Aid peaceful family is powerful limited company of supersonic testing instrument CNC Milling
