Description
Technical field
The present invention relates to a kind of ultra high efficiency explosion separation motor support water test unit.
Background technology
Under the whole world reduces the background of energy consumption, energy-saving efficient motor becomes whole world motor industry development common recognition.The states such as the U.S., Canada, Mexico, Brazil have formulated Energy Efficiency Standard and the Energy Efficiency Labeling System of motor the most in succession, such as, the NEMAPremium ultrahigh energy efficiency standard that the U.S. formulates on EPACT standard, and only by U.S.'s UL certification, European & American Market just can be actually entered.Require as 1.5MPa according to International Power committee's standard IEC 60079-0 and IEC60079-1 (GB3836.1 and GB3836.2) about the explosion separation motor support water pressure test that general inflammable and explosive occasion uses, and UL authentication requesting hydraulic pressure is domestic 4 times, i.e. 6MPa, therefore to make corresponding parts can reach this requirement, when doing experiment, must there be complete set, perfect fixture.And existing grip device can not meet 6MPa water pressure test requirement.
Summary of the invention
The technical problem to be solved in the present invention is: provide a kind of ultra high efficiency explosion separation motor support water test unit making electric machine stand can meet the 6MPa water pressure test.
The technical solution adopted for the present invention to solve the technical problems is: a kind of ultra high efficiency explosion separation motor support water test unit, during test, support axis is vertical state, including being arranged on vexed plate and support down depression plate on the support on electric machine stand；On described support, vexed plate and support down depression plate position with electric machine stand two ends seam；The upper and lower vexed plate of described support is bolted；On the one side of the upper and lower vexed plate of described support, pressing plate is installed；The line outlet of described electric machine stand is provided with the vexed plate of support line outlet；The described vexed plate of support line outlet is arranged on the inner side of pressing plate；Pressure water filling port it is provided with on vexed plate on described support.
Further, in order to improve sealing effectiveness during test, the end face of electric machine stand of the present invention is provided with O RunddichtringO at the plane contact of the upper and lower vexed plate of support.It is provided with sealing gasket between described line outlet and the vexed plate of support line outlet.
Further say, fastened by 16 hold-down bolts between the upper and lower vexed plate of support of the present invention；The upper and lower vexed plate of described support is steel plate, and thickness is 64～66mm.Than general thick about the 40mm of fixture.
The invention has the beneficial effects as follows, solve defect present in background technology that fixing by the upper and lower vexed plate of support makes support can meet 6MPa water pressure test requirement.
Accompanying drawing explanation
The present invention is further described with embodiment below in conjunction with the accompanying drawings.
Fig. 1 is the structural representation of the preferred embodiments of the present invention；
In figure: 1, vexed plate on support；2, support down depression plate；3, the upper and lower vexed plate connecting bolt of support；4, the vexed plate of support line outlet；5, pressing plate；6, pressure water filling port.
Detailed description of the invention
Presently in connection with accompanying drawing and preferred embodiment, the present invention is further detailed explanation.These accompanying drawings are the schematic diagram of simplification, and the basic structure of the present invention is described the most in a schematic way, and therefore it only shows the composition relevant with the present invention.
A kind of ultra high efficiency explosion separation motor support water test unit as shown in Figure 1, including electric machine stand, described electric machine stand has vexed plate 1 and support down depression plate 2 on support；On support, vexed plate and support down depression plate position with electric machine stand two ends seam；The two ends of the upper and lower vexed plate of support are connected by bolt 3 respectively；The one side of the upper and lower vexed plate of support connects pressing plate 5；The line outlet of electric machine stand is provided with the vexed plate of support line outlet 4；The vexed plate of support line outlet is arranged on the inner side of pressing plate, and support is provided with on vexed plate pressure water filling port 6.
In order to improve sealing effectiveness during test, the end face of electric machine stand is provided with O RunddichtringO at the plane contact of the upper and lower vexed plate of support.It is provided with sealing gasket between line outlet and the vexed plate of support line outlet.
Fastened by the hold-down bolt of 16 M24 between the upper and lower vexed plate of support；Upper and lower vexed plate attachment bolt lengthens reach, to strengthen hinge contact length, uses simultaneously and reaches 12.4 grades of intensity materials.
Assay device uses 45# steel plate, through forging, completes whole turnery processing on numerical control machining center.It is 65mm that the upper and lower vexed plate of support is thickness.Than general thick about the 40mm of fixture.
During test, support is fastened on assay device, both vexed plate 1 and support down depression plate 2 is first fastened on support with the two ends of airtight support during fastening, again the pressing plate 5 being fixed with the vexed plate of support line outlet 4 is fixed on upper and lower vexed plate, make the airtight firmly support line outlet of the vexed plate of support line outlet 4, the pressure water filling port water filling of vexed plate from support, until filling in support, and without any sluicing；After filling water, connect water pressure test pipe, progressively press, it is ensured that 6MPa, not blood pressure lowering in 10 seconds, illustrate that device is connected sealing very well with support, without sluicing, i.e. test is passed through.
The detailed description of the invention of the simply present invention described in description above, the flesh and blood of the present invention is not construed as limiting by various illustrations, person of an ordinary skill in the technical field after having read description can to before described detailed description of the invention make an amendment or deform, without departing from the spirit and scope of the invention.
