During the docking of conveyor belts must be clear conditions for their operation, that is, to the maximum extent to ensure that the size and properties of the level of stress.
conveyor belt has the following characteristics:
- construction;
- length, width, total thickness;
- the thickness of the working and non-working electrodes;
- the number and type of cloth napkins;
- tensile strength of a gasket and overall strength;
- 10% elongation at breaking load;
- type of coating rubber and purpose.
To assess the conditions of operation are:
- the appointment of the conveyor belt - the drive or load-carrying body;
- type of cargo (large, small, cold, hot, etc.);
- the length of the transportation, the angle of productivity, the actual load;
- diameters of the drums;
- speed of the cargo.
On long (200 m) conveyors need to be taken into account that conveyor belt can be extended, so the preference should be given tissues TLC EP.
number of spacers determined and Troughing traction load on the conveyor.It is important to pay attention to their compliance with the minimum possible diameter drums.Otherwise joint "thick" tape will not possess the durability.Belt speed also determines the durability of the joints.If you exceed a speed exceeding 10 m / s better to use the endless (seamless) construction tapes.
Joining belts , carried out with all the characteristics of the tape and operating conditions, is able to provide long trouble-free operation of the conveyor.
most favorable for docking of conveyor belts is the ambient temperature is around 20? C.
Work on the dock conveyor belts carried out by specialized teams, both in stationary production facilities and on-site teams directly to the customer.Before docking of conveyor belts need to evaluate their quality, since in accordance with the regulatory documentation may be allowed certain defects that affect the performance of the tapes.
Camber - curvature of the tape is checked rolling all or part of the bay on a flat surface.The presence of corrugations and folds of the core (ripple) - an incurable defect tapes.Plot with corrugations to be cut, or to schedule a tape on light conditions.The porosity of the plates - a sign of low-quality raw materials for the rubber and cured - makes the tape unusable.The presence of deep (3 mm or more) dents, metal and rubber solids - an incurable defect belts, they should be recommended for use in medium and light conditions.Availability polythickness plates or frame (30%) in width ribbons require additional imposing crude rubber on the assembled joint in its vulcanization.Hummocky surface of the plate - a sign of substandard cleaning press plates tapes manufacturer - leads to increased tire wear.
Cold vulcanization of joints is suitable for belts up to 1200 mm, used in light and medium terms, as well as belts wider than 1200 mm for light conveyors length not exceeding 50 m.
hot vulcanization of joints can be used in all cases of exploitationbelts, except for extreme conditions that require the use of seamless belts.
