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。
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 當水開關關閉時變量泵不供油,電流下降使電機處在空載待機狀態,這樣就有效達到節能。
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 摘要探討了由變數泵為液壓源、 2個閥控馬達為執行元件以及慣性負載組成的液壓控制系統的數學描述,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 甘蔗壓榨機液壓驅動系統采用斜盤式軸向柱塞變量泵與橫梁傳力內曲線馬拉松式定量液壓馬達組成容積調速閉式系統。
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 摘要針對液壓挖掘機在工作過程中存在的大量能量損失,根據泵的控制特性曲線,將發動機、變量泵、控制閥及負載作為一個動態系統來研究其節能問題。
