What are the reasons for slippage
Some customers walked there with the use of slip phenomenon discovered in the process , then the underlying causes of the formation of these scenes where it ?
Walks with normal operation, with a speed of not less than 95% of the roller speed . If the roller and the friction with Turn conveyor enough walks , walks with a slip so easily render
the scene . Caused friction roller and walks with a lot of the reason is insufficient , by common are: insufficient tension , load startup roller
Coefficient of friction cylinder looks inadequate and so on. The reason there is not enough tension : tension stroke inadequate , insufficient weight components , with long
walks , etc. ; roller enough of the original automated sorting machine appearance of the coefficient of friction > due to : wear rubber roller appearance package is too large, with a body too smooth wet
or sticky oil with body appearance sticky material (
Easily soluble rise ) .
Users should use still walks with front walks under investigation with the functional characteristics , such as the ability to prevent the onset of slip effect Hsu

Conveyor belt industry focus on issues
Although the current domestic shipping companies with the skills and product quality in order to have a qualitative progress, some companies can also be produced in a variety of
national and international norms fabric Incline Belt conveyor core and steel cord conveyor belt , and its product quality has been recognized by the international high-end users , but also points
conveyor belts career save
Concern the following issues :
First, is the choice of international norms progress . In recent years , China's export volume of belt conveyor is growing, do not accept the Chinese foreign general
specification of the product, pleading use ISO, Germany or the United States and other specifications. Thus, the conveyor belt enterprises must collect , digest relevant
international norms, and Weight Sorter press
Foreign skills specifications produced production, inspection, packaging and services.
Second, is to strengthen the special conveyor belt of discussion. To continue to add product product quality standard types and progress , strengthen high temperature
conveyor belt , cold conveyor belt , pipe conveyor belt , conveyor belt ripstop , high wear-resistant conveyor belt , ST5000 more high-strength steel wire rope conveyor belt
development
. As for transporting highly abrasive materials habit , progressive conveyor belt using life abroad than in Germany has developed a standardized surface abrasion rubber
materials, wear reaches 50 to 70 mm3 .
Third, is the development of energy-efficient low-drag conveyor belt . Current foreign countries have developed a low running resistance energy-saving conveyor belt and
transported over long distances on the use of machines , general conveyor belt operation drag coefficient from 0.02 to 0.025 , while the energy-saving conveyor belt at 0.016 or
so , you can cut operating
Energy consumption about 25%. It is understood that the newly developed Goodyear Easyrider conveyor belt is through changes in recipes to make conveyor belt down like tire
rolling resistance , like , a year can save 12% power consumption, save energy and help the user .
Fourth, the problem is the conveyor belt safety factor . Factory in the selection of current delivery wire conveyor belt , the domestic product safety factor of 7 to 9 ,
and in foreign countries is about 5, under the same conditions with the type of domestic transport higher than abroad 1 to 2 standard , add the equipment
Money and run energy , but also affect the product on the international market competitiveness declined conveyor belt safety factor is the key to progress conveyor belt joint
power and reliability.
