Embodiment 1
[0029] Such as figure 1 As shown, the present invention provides a portable transformer oil detection device for furfural, comprising an ultraviolet spectrum detection module, a reaction vessel 1, a cylinder body 2, a piston 3, an air inlet pipe 4 and an air outlet pipe 5, and the ultraviolet spectrum detection module is connected to the reaction vessel 1; the piston 3 is slidably located in the cylinder body 2, and one end of the piston 3 is connected to a power source to drive the piston 3 to move in the pipe body; There are air outlets on both sides of the upper end, so that the cylinder body 2 can be divided into two working rooms by setting air inlets and air outlets on the left and right sides of the cylinder body 2; the air inlet pipe 4 is connected to the air outlet on one side of the cylinder body And reaction vessel 1, the inlet end of air inlet is positioned at below the furfural oil sample; Air outlet pipe 5 is communicated with the air inlet of cylinder block 2 on...
Embodiment 2
[0041] Such as figure 1 As shown, in conjunction with the technical scheme of embodiment 1, in the present embodiment, the furfural detection device in the portable transformer oil also includes a communication pipe 18, and the communication pipe 18 is communicated with the first air inlet 13 and the air outlet pipe 5, so as to communicate by setting When the piston 3 moves in the cylinder body 2 during the air circulation process, the first air inlet 13 and the second air inlet 14 can both carry out air intake, and both the first air outlet 11 and the second air outlet 12 can Exhaust air to avoid that when the two working areas of the cylinder body 2 are performing gas circulation, because the valve-31 of the first air inlet 13 is closed to block the air outside the sampling pipe 50 from entering, causing no gas entering the one-side cylinder body 2 to exceed the pressure. The problem of large failures arises.
[0042] By arranging the connecting pipe 18, after passing throu...
Embodiment 3
[0046] Such as figure 2 and Figure 5 As shown, in combination with the technical solution of Embodiment 2, in this embodiment, the device for detecting furfural in portable transformer oil also includes a stirring shaft 21, an impeller 22 and a stirring rod 23, and the stirring shaft 21 is rotatably connected to the top of the reaction vessel 1 through a bearing On the sealant plug, the impeller 22 is connected to the stirring shaft 21 and is located in the air outlet pipe 5, and the stirring rod 23 is connected to the end of the stirring shaft 21; by setting the impeller 22, the gas passing through the air outlet pipe 5 drives the impeller 22 to rotate , so that the mixed solution of transformer oil and methanol in the reaction vessel 1 is stirred, thereby effectively improving the mixing efficiency, and fully mixing the furfural oil sample and methanol; During the movement, pump air to drive the impeller 22 to rotate, so that the stirring shaft 21 rotates to drive the sti...
