摘要

本設計通過了解注射機的工作原理及其機構組成，分析其典型零件的組成及動作原理，并通過液壓系統(tǒng)的工況分析，初步計算確定其主要技術參數(shù)，設計其液壓系統(tǒng)，選擇合理的液壓原件，使油泵電機的轉速與注塑機工作所需液壓的流量與壓力乘積成正比，將傳統(tǒng)的定量泵改造成變頻變量泵，從而使溢流閥的回油流量降到最小，無高壓節(jié)流能量損失，進而將傳統(tǒng)有高壓節(jié)流的“耗能型”注塑機升級為無高壓節(jié)流的“節(jié)能型”注塑機.
關鍵詞：注射機；液壓系統(tǒng)；技術參數(shù)；節(jié)能





ABSTRACT

This design constitutes through work principle and its organization that understanding injects machine, analyze constitute of its typical model spare parts and act principle, and pass the work condition that the liquid presses system analysis, the initial calculation make sure it main technique parameter, design its liquid to press system, choose a reasonable liquid to press an original piece, make the oil pump turn of electrical engineering soon with note Su machine discharge and pressure product that the liquid press that work need into a direct proportion, reform a traditional metered pump change the Pin change to measure a pump, make to overflow to flow the return of valve oil discharge to decline to least thus, have no high pressure to reduce expenses energy loss and then have tradition to"consume ability type" that the high pressure reduce expenses to note Su machine to get stripe for have no the high pressure reduce expenses of"economy energy type" note Su machine.
