油传动挤压机比水传动挤压机有突出的优点,在国外有很大的发展。我国七十年代初开始引进油传动挤压机,经过试制,目前已经形成系列化生产。《油传动挤压机速度控制系统的设计》通过理论分析和产品样机的试验,提出了“挤压速度和控制系统的选择”的原则和一此主要环节的设计思想。例如沈重设计制造的2500吨油传动挤压机的控制系统,吸收了由国外引进设备控制系统的优点,并结合我国电器元件生产的具体情况,经过负荷试车证明系统是可靠的,通过与引进设备对比可以看出一些技术指标,达到七十年代引进设备的技术水平,并且控制系统有简化,调节的灵敏度有提高。
Oil-driven extruders than water-driven extruders have outstanding advantages in foreign countries have great development. China’s early 1970s the introduction of oil-driven extrusion press, after trial production, has now formed a series of production. The design of speed control system of oil-driven extruder puts forward the principle of “selection of extrusion speed and control system” and the design idea of a main part through theoretical analysis and product prototype test. For example, heavy design and manufacture of 2,500 tons of oil-driven extruder control system, absorbing the advantages of the introduction of equipment control system from abroad, combined with the specific circumstances of the production of electrical components in our country, after the load test proved that the system is reliable, with the introduction of equipment Contrast can be seen some of the technical indicators, to the introduction of equipment in the seventies technical level, and the control system is simplified, the sensitivity of the regulation has improved.
