LS500 universal Frequency Converter Application on the building ingredient

1, entrance industry

Batching machine is one of a number of materials used such as: sand is given distribution automation equipment, mainly used in concrete construction industry as an alternative to artificial platform scale or volume metering mode. By mechanical transport right sub concrete, sand, stone and other materials, the material conveyed by said belt to the host, by setting concrete batching blending ratio, according to a set ratio with automatic batching and stirred into the concrete, are generally applicable to general construction sites, roads, bridges and other projects.

2, batching machine works and composition

Batching machine by feeding system for this three parts, the weighing system and electrical control system.

(1) Feed System: a storage hopper and feed device, the main function is to store the material and under the control of the control system, the said feed hopper.

(2) said System: The system is a critical part of the ingredients weighing machine, the said hopper, the suspension means and the weighing system sensors, batching controller and other components.

(3) Electrical control system: electrical control system is the ingredient of the core components, it is the function of the entire product, said dosing machine, a display, a variety of automatic batching operation and completion programs. The system controller from a furnish strong electrical circuit and two parts.

3, batching machine equipment functions implemented

Batching machine is equipped with a device for automatic foreground and supporting the use of the mixer. It user can automatically design concrete mix of sand, stone, cement and other kinds of materials 3-6 (with two concrete) ingredients, said electronic program, computer control, digital display, said cable having a remote accuracy, high precision ingredients, speed control, and other advantages, easy to each press of a key.

4, LS500 common application Frequency converter in dosing machine

PLC program to control the field using common LS500 Frequency converter of start and stop, to complete the blending process.

5, summary

Using the batching machine is Frequency converter general purpose input and output functions, LS500 general Frequency converter control algorithm optimized so that the control better performance, high precision, fast dynamic response, thereby enabling good process control to ensure that the process control reliability.
