This technical scheme also comprises: 1, rotation upper surface of fluted disc 17 or lower surface a plurality of grooves that distributing uniformly, and at the inside surface of fluted disc seat end cap 19 or fluted disc seat 14 noncontacing pickup 4 is installed, and is formed clearance fit with the groove of rotation fluted disc 17.2, contactless position sensor 4 is inductive position sensor or displacement-type position transducer.3, test axle 11 is connected by the spline teeth groove with rotation fluted disc 17.4, test axle 11 passes through spline 2 coaxial lockings with electric machine main shaft.5, the fluted disc number of rotation fluted disc 17 is 20-50.6, the groove number on rotation fluted disc 17 surfaces is 20-50.
By implementing technique scheme, obtain tangible technique effect.This tester is connected easy, reliable with tested motor; Test process safety, steady; Test result precision height, but the coasting time of testing of electric motors not only, but also testing of electric motors working speed, applied range.
Below in conjunction with the drawings and specific embodiments the utility model is described in detail.
Fig. 1 is an one-piece construction synoptic diagram of the present utility model;
Fig. 2 is the structural representation of test primary instrument of the present utility model.
Tester among Fig. 1 mainly is made up of test primary instrument 3, inductive position sensor 4, current sensor 6, A/D transition card 7, PC computing machine 8.To test primary instrument 3 by spline housing 2 and be serially connected with tested submersible electric machine with oil 1, current sensor 6 will be located on the lead cable 5 of submersible electric machine with oil 1.Inductive position sensor 4 and current sensor 6 are connected in A/D transition card 7 by plain conductor respectively, convert analog electrical signal to digital signal by A/D transition card 7 and send into computing machine 8.
Test primary instrument 3 is connected and fixed by adapter sleeve 10 and tested submersible electric machine with oil 1 integral body among Fig. 2, and bottom one side of adapter sleeve 10 is provided with electrical machine insulation oil lubricating cup 9, and the top of adapter sleeve 10 and fluted disc seat 14 are fixing by trip bolt 21; Test axle 11 passes adapter sleeve 10, fluted disc seat 14 and places the rotation fluted disc 17 in the fluted disc seat 14 to pass through flat key 18 screens locking, and the bottom of test axle 11 is connected with the main shaft of testing of electric motors 1 by spline housing 2; The top of fluted disc seat 14 and fluted disc seat end cap 19 are connected and fixed by attachment screw 20, and rotation fluted disc 17 is gone up rolling bearing 13 by two and fixed with fluted disc seat 14, fluted disc seat end cap 19 respectively; Test axle 11 is by rolling bearing 12 and jump ring 22 are fixing with adapter sleeve 19 down; Inductive position sensor 4 is fastened on the side of fluted disc seat 14 by its sheath 15, and the probe 16 of sensor is stretched in the cavity of fluted disc seat 14, with the peripheral coil tooth formation clearance fit of rotation fluted disc 17.
After assembling tester according to Fig. 1, Fig. 2, can test, its process is as follows:
At first connect the power supply of computing machine 8, enter the supporting TSS of the testing software starting state of computing machine and test instrumentation 3, connect the power supply of submersible electric machine with oil 1, electric machine main shaft rotates synchronously by test axle 11 driven rotary fluted discs 17, read the number of teeth that fluted disc 17 is turned in the unit interval by sensor probe 16 during the fluted disc rotation, form and the synchronous electric impulse signal of the number of teeth; Current sensor 6 output current signals simultaneously like this.Behind the two paths of signals input A/D transition card 7, convert digital signal to, input computing machine 8.The tachometer value of the tested submersible electric machine with oil 1 of computer-automatic collection, this moment, the output valve of current sensor 5 was " 1 ".
Cut off the power supply of submersible electric machine with oil 1 then, current sensor 6 is output as " 0 ", changes the coasting time test data collection state of submersible electric machine with oil 1 at 5 milliseconds of TSS of testing software with interior activation computing machine 8.Because during submersible electric machine with oil 1 normal the operation, the electric impulse signal frequency that sensor probe 16 is read is higher, therefore earlier electric impulse signal is delivered to the counter card, gather the currency and the working time of counter during computing machine 8 image data with equal intervals, and form the ephemeral data file.Slide in the process at submersible electric machine with oil 1, computing machine 8 is image data constantly, and after submersible electric machine with oil 1 stops, computing machine also will continue Value Datas such as collecting part.When carrying out data processing, software TSS differentiates the data district's starting point of successively decreasing automatically, and the flex point that finds data to equate.Can obtain the coasting time of submersible electric machine with oil 1 then by 2 statistics.
Above test process has used computing machine 8 to carry out data acquisition, processing, and the automaticity height if position transducer 4 is connected use with current sensor 6 with other instrument, can be realized the purpose of accurately measuring equally.
