This paper introduced the main design of silicon dioxide filter (SDF) hydraulics system and the design and fulfillment of the modification of SDF hydraulics control system using Programmable Logic Controller （PLC）technology. The SDF hydraulics equipment is composed of the hydraulics system and the electrical control system, This plan allows both auto-control and manual control. However, the control of SDF hydraulics equipment is the most important part in the whole SDF. Currently, most of the SDF hydraulics equipments are controlled by using relay combined with discrete electronic elements. This control needs complicated electronic circuit and many relays, and this will cause low reliability, high failure rate, and many daily maintenance. Along with the development of PLC technology, PLC is applied in the control of SDF hydraulics equipment and replace of the original hydraulics equipment control circuits. After the SDF hydraulics equipment control system modified with PLC, its control effect is far better than that of the original system, and the reliability is also improved greatly. This designing plan has broad applied prospect in the modification of the hydraulics equipment control system in various machines and devices.

The "paper introduced carries on the transformation to the
diatomaceous earth purifier hydraulic system main body design as well
as using the PLC technology to the diatomaceous earth purifier
hydraulic control system the design method and the implementation
process. The diatomaceous earth purifier hydraulic unit is composed by
the hydraulic system and the electrically controlled system, this plan
may use the automatic control and the hand control. But regarding the
diatomaceous earth purifier in the hydraulic unit check, is the entire
diatomaceous earth purifier most important part. At present the
diatomaceous earth purifier hydraulic unit check mostly uses relay
Canada to establish separately the electronic component the control
mode. This kind of control mode electronic circuit complex, relay use
quantity many, creates the electricity control section reliability
badly, the failure rate high, the routine maintenance quantity is big.
Along with the programmable controller (PLC) the technical
development, applies the PLC check technology in the diatomaceous
earth purifier in the hydraulic unit check, substitutes for the
original hydraulic unit check line. The diatomaceous earth purifier
hydraulic unit control system after the PLC transformation, the check
effect greatly surpasses the original systems control effect, the
reliability greatly enhances. Enhanced the reliability which the
diatomaceous earth purifier device uses, this design proposal in the
computer device hydraulic unit control system transformation, has the
broad application foreground. "

Papers presented to the diatomite filtration machines hydraulic system design and applications Plc technology on the main diatomite filtration machines hydraulic control system design methods and achieve the transformation process. Diatomite filtration devices aircraft hydraulic systems and motor control system by hydraulic composition, the programme can automate and manual control. For diatomite filtration machines, hydraulic control devices, is the most important part of diatomite filtration machines. Currently diatomite filtration machines hydraulic devices are used to control relays and electronic components separation control. Such control means complex electronic circuits, the use of a large number of relays, resulting in poor reliability of the electrical control components, the failure rate is high, the volume of large routine maintenance. With the programmable controller (PLC) technology, the Plc control technology for diatomite filtration machines, hydraulic control devices, replacing the original hydraulic control circuit devices. Diatomite filtration machines hydraulic devices controlled by the Plc system transformation, the results significantly better than the original control system control results reliability greatly improved. Raised diatomite filtration equipment used in aircraft reliability, the design of programmes in the hydraulic machinery equipment installed control systems transformation has broad prospects for application

The thesis introduces to filter the machine liquid to press the system corpus design and the application PLC techniques to the 硅藻 soil to filter the machine liquid to press to control the design method that the system carries on the reformation and carry out the process to the 硅藻 soil.The 硅藻 soil filters the machine liquid to press to equip to be pressed the system and electricities by the liquid to control the system to constitute, this project can adopt the automatic control and hands to move the control.But filter the liquid in machine to press the control of the device to the 硅藻 soil, is the whole 硅 藻 soil to filter the most important part in machine.Currently the 硅藻 soil filters the control that the machine liquid presses the device to adopt the control method that adds to sign the electronics component separately after the electric appliances mostly.This kind of control the way electronics circuit complications, use the quantity after the electric appliances much, result in the electricity control part of credibility bad, break down the rate high, support to have great capacity usually.Along with the technical development of programmable controller( PLC), in the control that the PLC controls the technique application to filter the liquid in machine to press the device in the 硅藻 soil, replace the original liquid to press to equip to control the circuit.The 硅藻 soil percolation machine liquid presses to equip to control the system after PLC reformation, control the result consumedly better than original system control result, the credibility raises consumedly.Raising the 硅藻 soil filters the credibility of the machine equipments usage, should design the project in the liquid of the machinery equipment press equip control the system reformation, have vast of applied foreground."
