The present invention is achieved in that
This spectrum maker comprises laser instrument, maker body and the spectrum Receiver setting gradually along a straight line.Maker body interior is provided with optical fiber, and the inside of optical fiber has through hole.The two ends of maker body are provided with sapphire sheet and the gas-tpe fitting passing for laser, and gas-tpe fitting is communicated with through hole.Spectrum Receiver is connected with for showing the computing machine of gaseous spectrum.During the work of this spectrum maker, gas to be measured enters the through hole of optical fiber from the gas-tpe fitting near laser instrument, then from the gas-tpe fitting near spectrum Receiver, discharges.Meanwhile, laser instrument sends laser, from the sapphire sheet of maker body one end, injects, and enters the body transmission of optical fiber, from the sapphire sheet of the other end, penetrates, and after then being received by spectrum Receiver, passes to computing machine, then by computing machine, is generated and is shown.The gas to be measured of this spectrum maker is mainly mud logging gas.
Further, maker body is straight square column, and square column comprises left attached column and right attached column, between left attached column and right attached column, is bolted.This connected mode makes the assembling of shell and dismounting become very convenient quick.
Further, maker body two ends are provided with optical fiber dop, and optical fiber dop is provided with mounting hole, and sapphire sheet is arranged in mounting hole.This set makes the installation of sapphire sheet more firm, makes the structure of maker body more stable simultaneously.
Further, in sapphire sheet, be provided with hold-down ring, make sapphire sheet keep fixing, guarantee spectrum projection.
Further, between hold-down ring and sapphire sheet, be provided with "O"-ring, with enhanced leaktightness effect, reduce the loss of light, guarantee the projection of spectrum.
Further, maker body interior is provided with two optical fiber compression bars and two optical fiber clamping pads.This set makes optical fiber keep vertical tightening state, guarantees the high efficiency of transmission of light and gas.
Further, maker body is made by aluminium alloy, and surface is oxidized black processing.Aluminium alloy density is little, and plasticity is good, and processing is simple.Surface can be effectively antirust through the black processing of peroxidating.
This spectrum maker adopts the optical fiber with through hole to transmit laser, has the advantages that transmission quantity is large, loss is low, antijamming capability is strong and with low cost, and the through hole of inside of optical fibre is for transmitting gas to be measured, to realize light transmission gentle time.This spectrum maker also adopts the sapphire sheet with good thermal conductivity performance to supply laser through projection, can test out efficiently and accurately the Raman spectrum of surveyed gas, and by Computer display out.
