Abstract:

Application of transient electromagnetic method, carries on the cavern blasting blind detection and recognition of feasibility study. Test to establish the electromagnetic background field, and then in the cavern preset benign conductor and measured after eliminating the background field, in the electromagnetic field transient to do the electromagnetic measurement again after blasting. Benign comparison before and after blasting preset the change of the conductive body eddy current field, realizes the cavern blasting blind shot detection and identification of purpose. The test results show that the target when the aluminum box buried depth of no more than 30 m, transient electromagnetic method can clearly identify the position of the aluminum box; When the aluminum box buried depth after more than 30 m, aluminum box formation of the secondary vortex field level, not sure the deep buried depth and position of the aluminum box.

Frontiers in Energy 2022, Volume 16, Issue 6, Pages 916-930 doi: 10.1007/s11708-022-0838-4

Abstract: crankshaft, the related piston motion control is a challenge for the FPLG which causes problems such as misfireAimed at resolving the problems as misfire, a single-piston FPLG prototype has been designed and manufacturedThe root cause of this misfire was then identified as the poor scavenging process, and a compressed air
