You know that people do a lot of tests before they use retrogressors, in order to ensure that they can use them properly
1. Free working tests
Retrometers will be installed on the test stage, with an electrically driven reversible inner circle rotated at zero. 5h, there should be no anomalies such as overheating。
2. Reverse performance test
Retrometers will be installed on the test stage to perform 100 retrogressive exercises with a rated reversibility rectangular effect, and the work should be reliable and without anomalies。
Non-exposure rotation tests
Wedge assembly of reversible units is installed on an ungraded test table, electrically drives wedge assembly to rotate, and determines the rate of rotation of the inner circle of the retrogression when it separates from the outer circle。
4. Resistance rectangular test
Retrometers will be installed on the test stage, electric power-driven reversible inner circle rotated at 1,000 r/m, and retrofitting the resistance f, f - within the axis centre of the arm, vertically with the axis of the inverter, within the surface of the axis, n; b - the centre of the offaxis to the centre of the inverter, m; - the angle of the link between the resistance f and the centre of the inverter, in the determination plane。
5. Temperature test
Jb/t 9015-19995 is installed on the test table with an electrically driven reversible inner circle rotated at a rotational rate, measuring the surface temperature and ambient temperature of the outer circle of the rebusters every 15 years using a semiconductor point thermometer until the heat balance (the temperature is the same three times in a row), and the difference between the outer circle and the ambient temperature is the reverse temperature。
6. Life test
Retrometers will be installed on the test stage, performing 105 reversibilitys under a rated reversible rectangular effect, after which no damage such as erosion, plastic deformations and cracks will occur in the inner circle, outer circle and the surface of the wedge。
