Description
Technical field
The utility model relates to a kind of determinator that is used to measure gas content of oil.
Background technology
In existing oily air content analyzer, have magnetism stick and inwall wire netting in the degas chamber, the oil sample that the injects inwall wire netting of flowing through, stirred by magnetism stick again, so that deviate from gas in the oil, because the gas content that magnetism stick stirs in inhomogeneous and oily is smaller, this degassing mode is difficult to make the measurement result poor repeatability of this oil air content analyzer with gas in the oil evenly, fully deviate from; In addition, when this oil air content analyzer is measured, need waste oil is directly arranged to atmosphere at every turn,, make test period longer so need carry out repeatedly pressurization pressure and vacuum pumping to degas chamber; In addition, must slowly inject during the oil sample of injection and along inwall wire netting trickling, make the oiling process slower, this makes the test period lengthening again.
Summary of the invention
The purpose of this utility model is to provide a kind of measuring repeatability good and save the oily air content analyzer of test period.
The technical scheme that realizes above-mentioned purpose is: a kind of oily air content analyzer, comprise differential pressure pick-up, the control circuit that is electrically connected with differential pressure pick-up, degas chamber and connecting line and control corresponding valve, degas chamber has oil sample inlet and oil sample outlet, and the oil sample inlet taps into oil pipe and operation valve V thereof
2, degas chamber inside is equipped with the aerofoil fan of a blade shaft horizontal at least, and the oil sample outlet of degas chamber is by flowline and operation valve V thereof
4Be connected in sump tank, vacuum-pumping tube and operation valve V thereof
5Be connected malleation tracheae and operation valve V thereof with sump tank
7Be connected with sump tank, sump tank is by another vacuum-pumping tube and operation valve V thereof
9Be connected draw-off pipe and operation valve V thereof with degas chamber
6Be connected with sump tank, degas chamber is by detector tube and be parallel with operation valve V
3An end of differential pressure pick-up connect.
After adopting technique scheme, because the aerofoil fan of a blade shaft horizontal is housed at least in degas chamber inside, adopt aerofoil fan that the oil sample that falls is carried out strong stirring diffusion, allow in the oil gas evenly, fully deviate from, so the good reproducibility of measurement result, measurement result is also more accurate, reliable simultaneously; Again owing to pass through flowline and operation valve V thereof in the oil sample outlet of degas chamber
4Connect sump tank, this sump tank can be stored the waste oil sample of repeatedly finishing, rather than the waste oil sample is discharged into atmosphere at every turn, thereby each measuring operation has been reduced vacuumize number of times, only need take out vacuum one time at every turn, has saved test period; In addition, the oil sample of degas chamber injects and can directly arrive aerofoil fan and on every side, stirs diffusion fast, and this has also further saved test period.
