Analysis of Hongda Nylon idler

Idler is an important part of belt conveyor. Hongda Engineering plastic factory after more than six years of improvement, application, developed according to the use conditions of a material containing nylon, ultra-high polyethylene, metal parts and other mixed parts of the new roller, in order to facilitate the name, named "nylon roller".

First, corrosion resistance

Because the outer component of the roller is made of plastic material, it is resistant to corrosion of weak acid, weak alkali, salt and organic solvent. In the chemical industry such as fertilizer plant, alkali plant, salt plant and coking plant, the corrosion resistance effect is particularly obvious. In the same corrosive environment, its life is 5-6 times that of the metal roller, called other general plastic roller long life 2-3 times. For example: Hubei Xinyangfeng 12 years ago, the location of harsh environment using metal and other materials roller life is not more than half a year, as short as more than ten days; Nylon idlers in our factory have a life of 1-2 years or more, and some of them are still in use for 16 years.

Secand, dustproof performance

Hongda independent research and development of the design of the "integrated labyrinth" dustproof device, the selection of three national inspection free bearing factory double seal dustproof bearings, before assembly with lithium grease, fine production, it is difficult to pollute the bearing. For example: Guizhou Fuphosphorus Mining Co., LTD.

Thrid, waterproof performance

Hongda design and production of roller, both ends of the dustproof cover screenshots in the drum, enough to make water block outside, even occasionally into a little water, there are labyrinth sealing ring and integral dustproof cover block, avoid the bearing is stuck lead to roller stop phenomenon, greatly reduce the accident downtime time. For example: Sanning Chemical synthetic ammonia gas transport slag belt 14 years ago using metal roller life only three months, using our factory nylon roller life extended to more than a year) stable running time.

Fourth, small friction coefficient

Hongda production of roller itself friction coefficient is small, excellent self-lubrication performance, roller body surface smooth, belt has a certain protection. So I plant production of nylon roller can greatly salt plant belt service life.

Fifth, small power consumption

The roller itself is light in weight, is about 1/7 of the metal roller, easy to install, rotating resistance is small (3.3-3.5N). Therefore, when the belt is running, the click will not consume more electricity because the weight resistance of the customer roller itself is too much.

Sixth, low noise

Hongda production of roller outer circle scene runout (0.5-0.7) mm, smooth operation. Whether indoors or outdoors, the noise of (3-7) phenbenzene alone does not have much effect on the overall environment.
