Abstract
The utility model discloses a pressure-tight test device for a medium-sized/small-sized explosion-proof motor casing. The pressure-tight test device comprises a sealing gasket and a water injecting port sealing plate connected below the sealing gasket, wherein a groove is formed in the sealing gasket; a thread hole is formed in the middle of the water injecting port sealing plate; a pressure water pipe is fixed in the thread hole; through holes are formed in the peripheries of the sealing plate and the sealing gasket; and the sealing gasket and the sealing plate are fastened on a flange on the periphery of a window by bolts mounted in the through holes. The pressure-tight test device disclosed by the utility model has the advantages that workers' labor intensity can be lowered; the test efficiency is improved; the volume is smaller; and the occupied area is reduced.
Description
Technical field
The utility model relates to fire proof motor inspection and test field, the Withstand test device field of especially middle-size and small-size fire proof motor.
Background technology
Fire proof motor is a kind of motor that can use in containing the place of flammable explosive gas, the overpotential test of GB3836-2010 centering small anti-explosion motor housing requires: in the flood-pot-test, static pressure is 1.5Mpa in the electric machine casing, keeps at least 10s, during can not seep water, leak.
The Withstand test device of existing middle-size and small-size explosion-proof motor shell generally adopts gantry frame structure, installs by screw rod or hydraulically powered pressure head in the upper beam of portal frame, and device has water filling port, the water delivering orifice of press water in the base of portal frame below.Explosion-resistant enclosure with fire proof motor during test vertically is installed on the described base, and described water filling port, water delivering orifice are covered in the motor housing; In both ends of the surface up and down packing washer is installed; Pressure head on the portal frame compresses explosion-resistant enclosure downwards afterwards, again by water filling port fast water injection in the explosion-resistant enclosure, discharge the viewing window of original air from shell in the shell, closed window mouth dividing plate when treating that water level rises to viewing window, inject the press water through the high-pressure pump pressurization in the water filling port, keep a period of time after shell hydraulic pressure inside reaches 1.5Mpa.By water delivering orifice the water in the shell is discharged after finishing test.Such Withstand test device is bulky, highly generally can reach the 2-4 of explosion-resistant enclosure length doubly, and floor area is also larger; The explosion-resistant enclosure of fire proof motor is very heavy, and the labour intensity that is installed on the test unit base is very large, and the preliminary work time of carrying out a test is long, and test efficiency is low; The cost of device is higher, safeguards also inconvenient.
The utility model content
The applicant is low for existing Withstand test device use inconvenience, test efficiency, the problem that while is bulky, floor area is large, improve research, the Withstand test device of another kind of middle-size and small-size explosion-proof motor shell is provided, thereby can reduce workman's labour intensity, improve test efficiency, and small volume, reduce floor area.
A kind of Withstand test device of middle-size and small-size explosion-proof motor shell comprises packing washer and the water filling port seal pad that is connected thereunder, and there is groove at described packing washer middle part, and described water filling port seal pad middle part has threaded hole, and penstocks are fixed in the described threaded hole; Have through hole around described seal pad and the packing washer, the bolt that is installed in the described through hole is fastened on described packing washer and seal pad on the flange of viewing window periphery.
The beneficial effects of the utility model are as follows:
End cap is installed at the explosion-resistant enclosure two ends first when 1, testing, is made it and body seal; By the fast water injection in the explosion-resistant enclosure of the viewing window on the shell, when treating that water level rises to viewing window, the utility model is installed on the viewing window, by penstocks injection pressure water in the shell, the withstand voltage properties of test shell, whole process need not mobile or the upset explosion-resistant enclosure, and labor strength reduces, the time of test also shortens greatly, improves test efficiency;
2, the utility model is simple in structure, and volume is small and exquisite, and floor area is few during test.
Description of drawings
Fig. 1 is front view of the present utility model, and packing washer is positioned at water filling port seal pad the place ahead among the figure.
Fig. 2 is the A-A cut-open view of Fig. 1.
Fig. 3 is that the utility model is installed to behind the explosion-resistant enclosure cut-open view along the viewing window center.
Fig. 4 is the partial enlarged drawing at A place among Fig. 3.
Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described.
As shown in Figure 4, the utility model comprises packing washer 9 and the water filling port seal pad 3 that is connected thereunder, and there is through hole at packing washer 9 middle parts, and water filling port seal pad 3 middle parts have threaded hole 11, and penstocks 1 are fixed in the threaded hole 11 by threaded connector 2; Have corresponding through hole 10 around water filling port seal pad 3 and the packing washer 9, bolt 6 is installed in the through hole 10; Have the viewing window 7 of rectangle on the explosion-proof motor shell 4, the flange (8) of viewing window 7 peripheries has been established threaded hole, and bolt 6 is fastened on water filling port seal pad 3 and packing washer 9 on the flange 8 by described threaded hole.
As shown in Figure 1 and Figure 2, water filling port seal pad 3 and packing washer 9 are rectangle, and the described through hole at packing washer 9 middle parts also is rectangle, and described through hole should not form the press water that penetrates in threaded hole 11 and stop.
As shown in Figure 3, Figure 4, during test, end cap is installed at explosion-resistant enclosure 4 two ends first, is made it sealing; To pass in the explosion-resistant enclosure 4 viewing window 7 of a common water pipe from shell, the discharge in the common water pipe is large, thereby can be to fast water injection in the shell; Air in the explosion-resistant enclosure 4 can be discharged from viewing window 7.Generally speaking, should be dissolved with rust preventive in the water of annotating.When treating that water level rises to viewing window 7, packing washer 9 and water filling port seal pad 3 orders are installed on the viewing window 7 of explosion-resistant enclosure 4, fixing with bolt 6.The threaded connector 2 of penstocks 1 mouth of pipe is screwed on the threaded hole 11 in the seal pad 3, in shell, inject the press water of exporting through high-pressure pump, still have a small amount of air in the shell this moment, but according to the existing experience understanding of those skilled in the art, a small amount of air can not exert an influence to the withstand voltage test of explosion-resistant enclosure, thereby does not need to remove again.Treat that the pressure in the explosion-resistant enclosure 4 reaches the numerical value of regulation, stop water filling, keep this pressure a period of time, if explosion-resistant enclosure 4 infiltration do not occur, leaks, explosion-resistant enclosure 4 does not occur infiltration yet, leaks with the faying face of two end cap, illustrate that then explosion-resistant enclosure 4 has reached design standards, the water of discharging afterwards in the explosion-resistant enclosure 4 gets final product.Whole process need not mobile or the upset explosion-resistant enclosure, and labor strength reduces, and also can improve the efficient of withstand voltage test simultaneously, and the setup time before the test is short, and test efficiency improves greatly.
In order further to be convenient to processing, can be at existing cover 5 middle part thread mill drillings 11, thus make water filling port seal pad 3.
More than describing is to explanation of the present utility model, is not to restriction of the present utility model, and the utility model limited range is referring to claim.In the situation of the utility model basic structure, the utility model can be done any type of modification.
