Control technology

　　 With industrial development, it makes greater and greater demands to control. On one hand, it

is because of the progress of automatic control technology. On the other hand, the industrialization in large production requests effective controls to the whole process. Not only is it a tendency, but also is a task that manufacturers and users should jointly study and achieve.
　　 Huada has accumulated many years experience in design and manufacturing. It has been devoted to researching and learning the advanced control technology from both home and abroad. With the new technology and design, electric automation is applied to the centrifuges to achieve continuous, reliable, stable and highly efficient automatic production control better suitable for the automatic control in the modern industry.
　　 The control systems for centrifuges have big flexibility to adjust the processing and equipment. We have delivered many control systems, which have very satisfied with different custo

mers, needs and have been applied very well. In practical, we have received friendly helps and sup － ports from our customers. It benefited both of us. It will describe some control systems below for your reference.
　　 Simple type: Automatic control can be achieved while the machine is running ；
　　 The electric control system usually is composed of common electric control components. The control system could control either manual or automatic, monitor the major equipment, make alarm for failure and give interlocking protection. 。
　　 General type: PLC based control
　　 As is well known, the programmable controller PLC based control system is widely applied to a large variety of industrial automatic control systems, because of its stable performance, good anti-interf

erence ability, reliability and safety, flexible configuration and programmability. Our company has developed the electric control system for centrifuge applying a combination of technology and components like PLC, frequency converter, braking assembly and hydraulic orpneumatic components. It is very suitable for the environments or situations,where the separation techniqueis complicated, and it makes high demands to techniques.
　　 Various set but flexible control programmes for options: It can automatically adjust from startup to loading materials and unloading. Various sets of processing data can be selectable and freely switchable according to the customers' needs.
　　 Good operational interface: It shows various data of techniques. It will give alarm indozens of situations when the abnormality in the equipment is detected, and has interlocking protection making the system working more safelyand reliably. The machine entirely can be applicable to flammable and explosive, poisonous, corrosive production environment. It is of high degree of automation without operator attention from startup to feeding, filtering, washing and discharging.
　　

Intellectualized type: multiple layer control interface PLC + PC jointly control, mine data and output
　　 Apart from the single PLC or PC control system mentioned above, it can connect to the on-site PLC through the communications ports, or connect to the PC in control center through the network appointed by users, to link to the customers' DCS or establish the individual live monitoring. The major functions of this control system are:

　　 1 、 With all fully automatic control functions as those of PLC based control system mentioned above
　　 2 、 PC monitor can display the processing of centrifuge and all working data of different equipments.
　　 3 、 Historic graphs of the various technique data are available
　　 4 、 Daily, monthly and annual production reports can be shown and printed.
　　 5 、 The on-site PC or central control can monitor several centrifuges' working status and remote control their start and stop respectively. 6 、 System has different grades of limit of authorization to prevent the illegal operation by the people without right.
