If the belt has a 2MM difference, will it affect the use? If the belt has a 2MM difference, will it affect the use? Can 6PK2155 replace 2160? Can 8PK1060 replace 1062? The customer asks like this ，I want to say that it can be replaced. In fact, many models with similar lengths are usually made by the same mold, For example: 6PK1062 and 6PK1060, the factory uses the same mold for production.Because each of our molds differs by 5mm, if you need 6PK1016, then we will use 6PK1015 molds to produce. In addition, the belt pulley can adjust the distance ， so the tolerance of the belt length will not affect the normal use of the machine.

Cause and solution of multi-ribbed belt Faults Cause and solution of multi-ribbed belt Faults Malfunctions during mechanical use are very tricky.When troubleshooting belt faults, in addition to replacing new products, finding the cause of the fault and mastering the correct use method can give full play to the performance of the belt and prolong its service life. The following table introduction the representative phenomena of belts. Please refer to the countermeasures in the table below when a malfunction occurs. Fault Cause Solution Slippage Belt tension slack Give moderate tension overload Widen the belt or increase the number of belts Small contact angle Widen the belt or place the correct diameter idler pulley Stained with oil or water Thoroughly remove oil or water. Install belt cover to prevent oil and water adhesion Premature rupture Load changes / suddenly overloaded . The transmission conditions used exceed the transmission capacity of the belt. Failed to hang belts in accordance with the required number of belts; not using the specified belt shape. The design can be changed, but the hanging belt must be the specified belt shape and number (please use a higher-level belt according to the use) Increase heat or excessive bending fatigue use(the diameter of the pulley is too small, the bending angle is too small, and the speed is too fast) Take measures to reduce heat; Change the design — change the pulley diameter, rotation speed, and bending angle Tension becomes loose and slips off Give moderate tension Cracked Use at high temperature Take exothermic measures Tension becomes loose and slips off Give moderate tension Continuous emergency stop or emergency start Change design Stained with oil, etc. Avoid oil adhesion and oil leakage The pulley diameter is too small, and the back tension causes the reverse bending to be too strong Change design Direct sunlight Attach the machine belt cover Surface cracking Tension pulley diameter is too small Use a larger diameter tension pulley The bending angle is too small Relax the bending width Tension becomes loose and slips off Give moderate tension Abrasion The pulley groove is rusty or the surface of the pulley groove is rough Evenly process the groove surface of the pulley Tension pulley diameter is too small Use a larger diameter tension pulley The angle of the pulley device is incorrect; the shape of the pulley is abnormal, and the angle of the pulley groove is not accurate Adjust the dislocation to below 1/3° , replace the pulley Excessive vibration The device of the machine body is unstable and resonates Fix the device part The belt tension is weak Change the distance between axes Belt length is not uniform Use a consistent belt combination Peel off The transmission conditions used exceed the capacity of the belt Hang the belt with the correct size, shape and number Used in a deformed state, the method of use causes increased bending fatigue Change design Make strange noises Emergency stop or emergency start Change the design to make the belt run smoothly Belt tension is too loose Give moderate tension overload Widen the belt or increase the number of ribbed used Machine belt choose error Choose the belt shape and specifications that meet the operating conditions ribbed belt flip Not suitable for pulley groove angle and device angle Dislocation aligned to the 1/3°or less Adhesion of the machine belt due to damage to the pulley groove or rough processing surface Replace the pulley The belt length is not uniform when using multiple belts Use a consistent belt combination
The material of conveyor belt The material of conveyor belt They must be durable, long lasting and resistant to a wide range of temperatures, moisture and chemicals. There are five main materials that conveyor belts are made out of: thermoplastics, metal, rubber, fabric and leather. Plastics include polyester, polyvinyl chloride, silicone and polyethylene. The metals are stainless and carbon steel, and the fabric materials are canvas or cotton. The most popular material is a rubber composite because it is flexible, resistant, smooth and seamless. It also doesn’t have any holes or openings. To increase strength, many belt materials contain additives, including fabric, steel, polyester or fiberglass. Many flat belts are actually composed of a core material and a covering. These belts are parts of many different types of conveyors, including troughed, inclined, horizontal, food grade and overhead conveyors, but they are not used in chain, pneumatic or screw conveyors. Choosing the right belting material is the most important specification involved with conveyor systems because the wrong material could compromise productivity or worker safety.
