The electric roller with the motor and reducer mechanism inside the cylinder and the external electric roller with the reducer mechanism inside the cylinder and external motor are mainly used in the fixed and mobile belt conveyor to replace the external driving device formed by the traditional motor reducer driving roller.
With the rapid development of the national economy and the continuous improvement of the technical level of the electric roller, the electric roller is used as the driving unit in the bucket elevator, as the active roller in the belt conveyor, conveying all kinds of scattered and pieces of goods. In case of emergency stop, electric roller with brake can be selected. Single rotation is required to prevent power failure and sliding of materials to be transported. Electric roller with backstop can be selected. For places with combustible gas, flameproof electric roller can be selected. In a word, the electric roller has the advantages of compact structure, high efficiency, low energy consumption, low noise, long service life, stable, reliable operation, good sealing, less occupation of site, convenient installation and maintenance, etc., which will be more widely used in metallurgy, chemical industry, building materials, coal, transportation, energy, grain, commerce, post and telecommunications, ports and other fields.
Scope of application:
1. It can replace the motor reducer type external drive device which is widely used at present. It can be used to form a belt conveyor to transport coal, ore, sand, cement, flour and other bulk materials, as well as hemp bags, equipment and other finished goods.
2. The structure is simple and compact, and the occupied space is small.
3. Good sealing, suitable for working place with high dust concentration, wet and muddy.
4. Easy to use and maintain, safe and reliable operation, long service life.
5. Less energy consumption, and easy to achieve centralized control.
6. It can meet the requirements of various backstop, braking, rubber coating, etc.
Applicable conditions:
a. The drum shall be installed horizontally, and the inclination angle shall not be greater than 5 degrees;
b. Ambient air temperature - 20-40 ℃;
c. The altitude is not more than one kilometer, and it can also meet the requirements of the roller used for more than 5000 meters by special design;
d. The temperature of conveying materials shall not exceed 60 ℃;
e. The voltage is 380V, the frequency is 50Hz, and it can also meet the requirements of 380 / 660V, 660 / 1140V.
