Detailed description of the invention
embodiment 1
A kind of secondary cooling area for continuous casting dynamic pressure detection system that the present embodiment provides, comprises pressure acquisition plane 12, flat board 10, at least one cistern 7 and at least one pressure sensor 1.
Pressure acquisition plane 12 is made for stainless steel, is of a size of 2000mm × 750mm × 3mm; Pressure acquisition plane 12 evenly offers spray holes 9, and the diameter of spray holes 9 is 1mm, and pitch of holes is 8 ~ 50mm, ensures that pressure that each pressure sensor 1 measures is under same state.
As shown in Figure 4 and Figure 5, dull and stereotyped 10, for being of a size of the bread board of 2000mm × 200mm.Pressure sensor 1 comprises pressure detecting mouth 3 and normal pressure mouth 4, and pressure sensor 1 is HM191 series of products HM191D-DS3AN-004DP, and wherein the external diameter of pressure detecting mouth 3 and normal pressure mouth 4 is 2mm, interior through being 1mm; Pressure sensor 1 is of a size of 17.4mm × 12.7mm × 11.4mm.Pressure sensor 1 is alternately disposed at the tow sides of dull and stereotyped 10, avoids influencing each other between each pressure sensor 1, and meanwhile, size and the circuit of consideration pressure sensor 1 are easy for installation, and two adjacent pressure sensors 1 are arranged alternatively up and down.
As shown in Figure 1, the top of cistern 7 arranges the import 6 of pyramidal structure, and the height of import 6 is 1/3 ~ 1/2 of cistern 7 height.The top diameter of import 6 and the ratio of base diameter are 1/10, and the tapered wall steeper of import 6 is impelled water smoke to dirty, avoided ponding.Small-bore one end of import 6 is communicated with spray holes 9, the pressure detecting mouth 3 of pressure sensor 1 is communicated with the perforate of import 6 sidewall by tube connector 5, according to the direction of the connecting pipe interface in the direction adjustment tapered pressure import 6 at pressure detecting mouth 3 place of pressure sensor 1.Above-mentioned tube connector 5 adopts rubber hose, and internal diameter d is 2mm.After the water smoke that spray holes 9 sprays into enters import 6, due to the taper of import 6, the ponding produced in tapered inlet 6 can be collected in cistern 7, the downward space of water smoke is increasing, the side wall surface not easily ponding blocking of import 6, the water produced also can not enter tube connector 5 and then enter pressure detecting mouth 3, damages pressure sensor 1.In addition, draining valve (8) is set bottom cistern 7, facilitates the draining of cistern 7.In the present embodiment, tapered pressure import 6 adopts lucite to make, and top internal diameter is 1mm, and base diameter is 10mm, and height is 10mm; Cistern 7 and import 6 are connected as a single entity, and also adopt lucite to make, diameter is 10mm, and height is 20mm; Draining valve 8 internal diameter is 2mm.
Meanwhile, also comprise a normal pressure pipe 11 communicated with atmospheric environment, as shown in Figure 2, normal pressure pipe 11 adopts stainless steel to make, and is communicated with by the normal pressure mouth 4 of tube connector 5 with all pressure sensors 1.As shown in Figure 3, the internal diameter of described normal pressure pipe 11 is greater than 40 with the internal diameter ratio of described tube connector 5, grows up in 2000mm, ensures that the reference pressure of pressure sensor 1 is not by the impact of working environment pressure.
Operation principle of the present invention is: (1) water smoke is sprayed onto in spray holes 9, enters import 6, is condensed into water droplet and flows to cistern 7 downwards along wall in import 6, when the dilutional hyponatremia of cistern 7 li, can be discharged by water by the draining valve 8 of bottom.The pipeline that the pressure of water smoke can be connected with pressure sensor 1 by import 6 transmits, and the Transfer Medium of this process is gas, does not have water and enters pressure sensor 1 and damage pressure sensor 1.(2) the reference pressure interface of pressure sensor 1 is all connected on the larger normal pressure pipe 11 of diameter, normal pressure pipe 11 communicates with the atmospheric environment of pressure tester external stabilization, so just can ensure that the reference pressure of sensor is metastable, thus reduce the measure error because the fluctuation of reference pressure causes.
In addition to the implementation, the present invention can also have other embodiments.All employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop on the protection domain of application claims.
