230= 253L min。
230 = 253L min.
b.高压系统:因-缸动作时夹紧缸不动作，故平均流量Q2=( 170. 4-37.4)/2= 66.5L/min,考虑系统的泄
b. High pressure system: because the clamping cylinder does not move when the other cylinders are in action, the average flow rate Q 2 = (170). 4 ≤ 37.4) / 2 = 66.5L / min, considering the leakage of the system
漏取Q2= 1.2x66.5= 79.8L/min。 第
Missing Q2 = 1.2x66.5 = 79.8L/min. No.
根据平均流量及工作状态，选用双级泵较合适。低压系统流量大，使用双泵供油则经济些。查样本选双级叶片泵: Pi=8MPa, Qn= 168L/min; Pr= 16MPa, Qn= 100L/min。对低压系统lv =Qn+Qn2= 100+ 168= 268L/min>253L/ min,对高压系统Qv=Qv2= 100L/min>79.8L/min。
According to the average flow rate and working state, the two-stage pump is more suitable. The flow rate of low pressure system is large, and it is more economical to use double pumps to supply oil. The two-stage vane pump: Pi=8MPa, Qn= 168L min, Pr= 16MPA, Qn= 100L/min. For low voltage system lv = Qn+Qn2= 100 + 168 = 268L/min > 253L/ min, for high voltage system Qv=Qv2= 100L/min > 79.8L/min.
