Treatment Of Steel Wire Rope Slippery

Steel Wire Rope slip is usually the following reasons:

1. The surface of the steel wire grease too much, resulting in reduced friction coefficient with the groove.

2. The surface of the Steel Wire Rope is seriously worn, resulting in reduced diameter and reduced friction.

3. Wheel groove material and Steel Wire Rope material strength ratio does not match, resulting in one of the two wear too fast, reduce the friction coefficient. (WeChat public number: elevator)

4. The gravitational pressure applied to the groove is not sufficient, resulting in insufficient pressure caused by the contact of the Steel Wire Rope with the wheel groove, thereby reducing the coefficient of friction.

Approach:

(1) check the rope groove surface is smooth, elevator Steel Wire Rope lying in the groove within the depth of the same. The method is to align the ruler along the axial direction of the tail wheel, and then measure the distance from the vertex of the Steel Wire Rope to the ruler. When the gap reaches 1.5mm, (WeChat public: elevator) should be re-turning or replacement traction wheel.

(2) Check whether the elevator Steel Wire Rope in the rope slot and skidding. When the gap between the Steel Wire Rope and the bottom of the groove is reduced to 1mm, the rope groove is to be re-turned. Rope groove in the incision under the edge of the thickness, when the Steel Wire Rope diameter φ13mm should not be less than φ12.5mm; when the wire diameter φ16mm should not be less than φ15.5mm.

(3) When turning the rope groove, please check that the ratio of the diameter of the traction wheel to the diameter of the Steel Wire Rope should be greater than 40.

(4) a slight slip of the Steel Wire Rope, the industry has a trailing wheel groove at the end of a narrow shallow groove treatment methods to solve the problem of slippery effect is obvious. However, this will lead to deterioration of the Steel Wire Rope force, not long-term use.
