A Study about Movable Belt Conveyor

1.Introduction of movable belt conveyor
Movable belt conveyor is a kind of lifting and transportation machinery, it is widely used in ports, stations, warehouses, freight yards and other freight places. For the port, the use of belt conveyor as the main loading and unloading equipment for the loading, unloading and handling of various bulk materials, bagged materials, small sundries and other goods. it has a high efficiency. However, in the actual loading and unloading work, there is often a factor of low operating efficiency. Therefore, it is difficult for these efficient loading and unloading equipment to produce a high level of efficiency.After the cause and effect analysis of low efficiency, we know that the most important adverse factors are the unbalanced loading rate and frequent starting problems.This disadvantage seems to have become an inevitable factor.How to ensure the normal operation of loading and unloading equipment and how to make the loading and unloading equipment give full play to the best efficiency level through some technical control factors without changing such adverse factors has become one of the main topics of energy saving and consumption reduction in ports and improving the efficiency of loading and unloading work.
The efficiency of movable belt conveyor is mainly reflected in the index of power source consumption.In the loading and unloading operation, the load is uneven due to the continuous operation of the loading and unloading equipment.Also allows when the no-load time is greater than a certain specified value, loading and unloading equipment for a stop, stop intermittent phenomenon.As a result, the main motor of the loading and unloading equipment is wasted in the consumption of electric energy due to the uneven load and frequency fluctuation.Through the energy balance test of the loading, unloading, and moving working site, when there is no load or uneven load, as well as the working condition of frequent starting, the efficiency level of the motor is only about 14.99%.As a result, the efficiency of the motor is extremely poor and the loss of power is extremely serious. Therefore, it is necessary to adopt energy-saving technical measures to reduce the power loss of loading and unloading equipment and improve the level of loading and unloading work.

2.Operating Environment of the Equipment
The transported goods of the movable belt conveyor are generally bulk food, and the specific gravity d of this kind of cargo is relatively small, and the bandwidth B of the transporter is generally 500mm , and the belt speed is generally 2. 5m/s, so its delivery efficiency is relatively low.
3. Select the power saving device
Can the movable belt conveyor be equipped with a power saving device? The technical test and feasibility study considers that the energy-saving device is installed on the portable belt conveyor. For the 380V three-phase asynchronous motor operated under the “△” connection, it is very suitable to install the xsz series power saver. When the belt conveyor is in working condition, as the load changes, during the starting condition, etc., “△” is performed. The repeated switching of "Y" is technically feasible. In addition, the x s z series energy-saving appliances have the advantages of small size, light weight, easy installation and no damage. The xsz series power saver also has the same function as the mobile belt conveyor motor, and the control circuit is the same.
In conclusion, portable belt conveyor is one of the most used machinery
