摘 要本次設(shè)計是圍繞節(jié)能、環(huán)保熱點來展開研究，設(shè)計了由 PLC 系統(tǒng)控制，液壓系統(tǒng)來完成動作的垃圾壓榨機。 本次課題選用液壓傳動來作為其動作裝置，具有傳統(tǒng)的液壓傳動的優(yōu)勢，如穩(wěn)定性好，傳動效率高。同時，也在系統(tǒng)中加入了監(jiān)測壓力表等設(shè)備，更好的保證了系統(tǒng)能穩(wěn)定的運行，同時也為維修提供了方便。在設(shè)計過程中，通過要求的壓力及流量等，選擇了當(dāng)今標(biāo)準(zhǔn)液壓器件，以保證一旦設(shè)備出現(xiàn)故障，以便更換器件，保證工作連續(xù)性。由于此次設(shè)計的垃圾壓榨機工作環(huán)境比較差，需要的適應(yīng)性強，可靠性高，抗干擾能力強的控制系統(tǒng)，所以本次課題的控制系統(tǒng)采用的是 C20P 系列 PLC。C20P 輸入輸出繼電器點數(shù)為 20 點其中輸入繼電器 12 點，輸出繼電器為 8 點。其中 3 個輸入點由行程開關(guān)控制，來保證動作位置。急停，啟動，停止各一個輸入點，還有一個壓力繼電器來控制快進轉(zhuǎn)工進的動作過程。輸出繼電器用來控制電磁閥的電磁鐵。關(guān)鍵字：液壓系統(tǒng) 垃圾處理 壓榨機 PLC ABSTRACTThis issue is a focus on energy saving, environmental protection and hot spots to expand the research, design by the PLC control system, hydraulic system to complete the movement of waste crushing machines. The topic chosen as the action of hydraulic transmission equipment, hydraulic transmission with traditional advantages, such as good stability, transmission and high efficiency. , It is also added to the system of monitoring pressure gauges and other equipment, and better able to guarantee a stable operation of the system, and also for the maintenance of convenience. In the design process, by the required pressure and feed speed, etc., choose the standard of today's hydraulic components to ensure that once the equipment failurer to replace the device, to ensure continuity.As the current design of garbage squeezing machine working environment is poor, the conditions of adaptability, high reliability and strong anti-interference ability of control system are needed, so this issue of the control system is the C20P series PLC. C20P input and output relay points for 20 points including 12-point type relay, the output relay for 8 points， in which three input points from the trip switch control, to ensure that action here. Emergency stop, start, stop each one input point, there is a pressure relay to control the fast-forward the process of changing jobs into the action. Output relay used to control the solenoid valve solenoid.
