Use of variable pump , the oil temperature is not high , and can substantially reduce water wastage 采用變量泵,油溫不高,能在很大程度上減少水資源的浪費(fèi)。
When the switch is closed , the variable pump has no oil supply , the current decline will keep the motor in empty waiting state , thus effectively save energy 當(dāng)水開關(guān)關(guān)閉時(shí)變量泵不供油,電流下降使電機(jī)處在空載待機(jī)狀態(tài),這樣就有效達(dá)到節(jié)能。
This paper is focused on the mathematical description of hydraulic control system , in which the hydraulic power comes from variable pump , the actuators are two valve - controlled motors , and the load is purely inertial 摘要探討了由變數(shù)泵為液壓源、 2個(gè)閥控馬達(dá)為執(zhí)行元件以及慣性負(fù)載組成的液壓控制系統(tǒng)的數(shù)學(xué)描述,并給出了其線性化模型。
A volume speed controlling system is selected on the fluid drive system of sugarcane mill , which consists of cam type axial piston variable pump and ram marathon fixed motor . an individual hydraulic system is adopted by the up - axis of the mill 甘蔗壓榨機(jī)液壓驅(qū)動(dòng)系統(tǒng)采用斜盤式軸向柱塞變量泵與橫梁傳力內(nèi)曲線馬拉松式定量液壓馬達(dá)組成容積調(diào)速閉式系統(tǒng)。
In the light of significant energy losing during the hydraulic excavator working , a dynamic system was made up from the diesel engine , the variable pump , the control valve and the load to cut down the losing energy from a systematic approach based on the control characteristics of the system elements 摘要針對(duì)液壓挖掘機(jī)在工作過程中存在的大量能量損失,根據(jù)泵的控制特性曲線,將發(fā)動(dòng)機(jī)、變量泵、控制閥及負(fù)載作為一個(gè)動(dòng)態(tài)系統(tǒng)來(lái)研究其節(jié)能問題。
