FU chain conveyor working principle characteristics and selection of presentation
FU chain conveyor (referred to as "chain transport machine") is combined with the advantages of similar products, transportation equipment generally summarized in the practical
application problems, comprehensive development of a new generation of more comprehensive domestic transportation equipment. The principle of advanced, novel structure
reasonable, energy efficient. Be
An ideal alternative conveyor. Has been widely used in building materials, chemical, thermal power, food processing, mining, machinery, metallurgy, transportation, ports,
transportation and other industries.90 degree turn conveyor
1 Working Principle
Exist between the bulk material particles to the inner friction force and internal pressure, when the conveyor chain conveyor movement and accessories, bulk material in the slot
machine by the conveyor and conveyor movement direction tension in the same direction, the bulk particulate material room pressure, within a bulk material so that the friction
force increases. When this
Friction force is larger than the inner bulk material and the friction machine side wall, the bulk material will be moved forward along the direction of conveyor movement, and
increasing the internal pressure of the bulk material layer to ensure a stable state, thus forming the overall continuous flow, like water in general.
2 Typical materials can be transported
FU chain conveyor can transport powder, granular, small block materials a thousand species typical are: cement products, cement raw materials, sand, limestone, coal, coke 90 degree conveyor
powder, fly ash, sawdust, shredded ice, powder, urea, synthetic fertilizers, soap powder, baking soda, soda ash, stone
Ink, plastic particles, polyethylene, resin, potassium, ammonium sulfide, clay powder, quartz sand, iron ore, crushed slag, salt, starch, wheat, cotton, broken feed, malt sugar,
rice, corn, soybeans and other .
3 Key Features
(A) conveying capacity: with compared to other types of conveyors, FU chain conveyor is small, the advantages of big conveying capacity, it simply belt conveyor 1/5 of the space
or screw conveyor 2/3 Space can deliver the same flow rate of the material. Transport capacity of 6m  3 / h 500m 
3 / h.
(2) long service life, the use of low cost: alloy steel, heat-treated by the scientific processing of conveyor chains, their normal life of more than five years, the chain
roller life is not less than one year (the whole machine most wearing parts), thus ensuring a less amount of maintenance, greatly reducing the use of expenses, improve
(3) low energy consumption: With the inner friction material, so that most of the work done by moving parts are converted to active power. Greatly reducing the use of chain
conveyor hook material to its resistance to energy consumption is only 30% -60% of the screw conveyor.
(4) seals, security: machine fully sealed so that dust can seamlessly drill, easy to operate, safe, reliable operation.
(5) Process layout flexibility: choose any location in the cabinet to allow multiple types of material inlet and outlet can be elevated, ground or pit arranged horizontally or
climbing (≤ 15 °) installation.
4. Equipment selection
Proper selection and use reasonable care in order to give full play to the best performance of advanced equipment. FU chain conveyor in the selection, you should note the
following important parameters:
(A) the choice of chain speed
Users should first according to the performance of the material being transported, the state (abrasive, melt temperature, particle size) and other factors choice.
(2) the choice of models
Chain speed is determined, you can choose the best model based on throughput. Each model has a basic throughput. In the same throughput, select the larger models can reduce
chain speed, thus extending the service life, but also pumping capacity should not be too small, if the actual amount is less than the aircraft transporting more than 30%,
Occurs when using the material layer is too thin, the inner pressure is too small, resulting in idling, but increased wear.
(3) The choice of power
Once the model is selected, according to throughput, transmission length and process layout Conditions Select power and gear reduction ratio and assembly type. Drive power in
45Kw above, it is recommended to use Y series motor + hydraulic coupler + ZSY series reducer. Drive unit assembly type are: left loading
, The right equipment and back-mounted (only applies to power in less than 5.5KW XWD cycloid motor).
(4) the choice of material inlet and outlet
The size of the material inlet and outlet, users need to choose, the choice must be noted:
a. For illiquid or humidity of the material, generally should not be used to make progress spout, so as not to feed poor.
b. arrangement due to process constraints. When the first inlet from the tail shaft closer, generally should not be used motivated discharge.
c. This machine can be used multiple feed ports and a plurality of discharge ports, but can also according to user needs, providing band brake spout.
d. both the upper and lower cross-bridging chain transporting the plane, should the middle section of the bottom were used to spout (a band brake and two without brake) and both
sides of the inlet.
