闭式液压系统中,补油泵的作用是补偿在工作中由于泵、马达容积效率损失以及由冲洗冷却阀组中泄漏的流量,补油泵的参数设计在闭式液压系统的设计中非常重要.通过综合分析多方因素,提出补油泵排量一般选取主泵排量的20%~25%,补油压力通常设定为1.5~2.5 MPa.
閉式液壓繫統中,補油泵的作用是補償在工作中由于泵、馬達容積效率損失以及由遲洗冷卻閥組中洩漏的流量,補油泵的參數設計在閉式液壓繫統的設計中非常重要.通過綜閤分析多方因素,提齣補油泵排量一般選取主泵排量的20%~25%,補油壓力通常設定為1.5~2.5 MPa.
폐식액압계통중,보유빙적작용시보상재공작중유우빙、마체용적효솔손실이급유충세냉각벌조중설루적류량,보유빙적삼수설계재폐식액압계통적설계중비상중요.통과종합분석다방인소,제출보유빙배량일반선취주빙배량적20%~25%,보유압력통상설정위1.5~2.5 MPa.
In closed hydraulic system,the function of the charge pump was to supplement the loss of volume efficiency of the pump and motor,and the leakage flow in flushing of cooling valves during operation. The design of charge pumps parameter was very important in design of the closed hydraulic system. By analyzing all kinds of factors synthetically,it is put forward that the displacement of charge pump is selected commonly as 20% ~25% of the main pump,and the pressure is set generally as 1.5~2.5 MPa.
