Elevator Performance Test Project And Requirements

- Jul 03, 2017 -

(L) no-load test: in the car no-load state, the continuity of 40% of the case of continuous operation up and down for 90 min, with a precision of 5% AC and DC ammeter to measure the start of the traction motor, The current of the current three times, the maximum should be consistent with the motor of the corresponding technical requirements.

(2) Balanced load test: The car is measured at 40% to 50% of the rated load with no load on the same operating mode. Start, run up and down the current three times, the maximum should be consistent with the motor of the corresponding technical requirements. Up and down running current value should be basically consistent, the error should not exceed 5%. The traction machine should run smoothly and the brake is reliable.

(3) rated load test: the car placed in the rated load to the same load side of the running side of the traction motor start and up and down running current three times, the maximum should be consistent with the motor the corresponding technical conditions. The hoisting machine is operating normally and the brake coil, motor and reducer bearing temperature rise is within the permissible value (<60 ° C).

(4) overload test: disconnect the overload circuit, the car evenly placed lro% of the rated load and in the lower part of the appropriate height of the run, in the case of 40% power on the run of 3 () min, the elevator start, run, stop Normal, traction machine running reliable, no abnormal vibration and noise, the brake can be reliable braking.
