谁能帮我翻译出来,翻译成英语的,本人急???????

Engineering plastics is the plastic granulator pre-processing of raw materials necessary in a part of the common plastic processing equipment. The granulator first performance directly affects the quality of processed products, is an important link in the production. The products are designed to enhance the speed performance of the first granulator and improve the control equipment to improve product quality. Lines from the single-phase full-bridge rectifier circuit constitute the main circuit. Double-loop control circuit Speed system. Furthermore system also designed overvoltage protection, over-current protection, undervoltage protection lost pressure. protection, such as design, the system reliable performance, lower cost, to achieve wide range of stepless speed regulation is a practical Electromagnetic induction motor speed control by the speed control system
Key words: single-phase double-wide closed-loop control bridge
