Electrical Control System , For Plastic Sheet , Plate And Film
Production Machines
1. Introduction of our company's electrical system componentsOur company's electrical system mainly consists of the following
three types: (1) the electrical control system of the cast film
production machine (2) the electrical control system of the sheet
production machine (3) the electrical control system of the sheet
production machine. The system consists of the following
components: operation cabinet, operation panel, PLC, temperature
control meter, frequency converter, three-roller and tractor
controller, relay, circuit breaker, air switch, indicator light and
other components.
2. The function of our company's electrical control system
(1) Automatic control function. The volume of high-voltage and
high-current switchgear is very large. Generally, operating systems
are used to control opening and closing. Especially when the device
fails, the switch needs to automatically cut off the circuit, and
there must be a set of automatically controlled electrical
operation equipment. Automatic control of power supply equipment.
To
(2) Protection function. Electrical equipment and lines will fail
during operation, and the current (or voltage) will exceed the
allowable working range and limits of the equipment and lines. This
requires a set of detection of these fault signals and automatic
adjustment of the equipment and lines (disconnect, Switching, etc.)
protection equipment. To
(3) Monitoring function. Electricity is invisible to the eyes.
Whether a device is powered or powered off is indistinguishable
from the outside. This requires setting up various audio-visual
signals, such as lights and sounds, to conduct electrical
monitoring of the primary device. To
(4) Measurement function. Light and sound signals can only
qualitatively indicate the working status of the equipment (powered
or powered off). If you want to know the working status of
electrical equipment quantitatively, you also need various
instrument measuring equipment to measure various parameters of the
circuit, such as voltage , Current, frequency and power etc.
3. Overview of the electrical control systemThe so-called electrical control system refers to a combination of
several electrical components to realize the control of one or some
objects, so as to ensure the safe and reliable operation of the
controlled equipment. The main functions of the electrical control
system are: automatic control, protection, monitoring and
measurement. Its composition mainly has three parts: input part
(such as sensors, switches, buttons, etc.), logic part (such as
relays, electric shocks, etc.) and execution part (such as
electromagnetic coils, indicator lights, etc.).
Gwell machiney company absorbs and digests the experience and
advanced technology from other countries to improve the machine
design and processing technology. The main components used on the
production line are all qualified and famous brand, like Siemens,
ABB, JC-TIMES. The energy consumption of its complete sets of
equipment , intelligent, automation, safety standard, technology
standard, etc., have been at or near the world standard of the
product. Gwell has developped for over ten years since
2010. We have accumulated a lot of experience of electrical
system designing since the using conditions are different in other
countries.
Gwell Machinery is a high-tech enterprise, committed to providing
customers with plastic sheet, board, film and other extrusion
lines. Gwell can provide turnkey projects, such as stone paper
project, EVA solar film project, PP building formwork
equipment,etc. Gwell has a strong technical equipment strength and
key capacity, committed to high-end product development,
international market development. “Realize customer value" is the
company's long-term business philosophy.The manufacturing bases of
the company are located in Taicang, Suzhou, which is close to the
beautiful scenery of Shanghai, Yancheng Dafeng, the hometown of
Red-crowned crane, and Nantong, the hometown of Education and
longevity in China. It covers a total area about 150,000 square
meters. It has an annual production capacity of more than 200
extrusion lines of various types of sheet and board.
