Why does the concrete pump give the machine why low pressure Why low volume, low pressure?
High pressure; The height is related to the concrete model, I'm from zoomlion, hehe
High-pressure small displacement is work of oil into the oil cylinder piston rod tail oil so stressful because long enrich your time than the low pressure oil displacement is narrow, low pressure refers to the front working oil from the oil cylinder oil through because the piston rod is so low pressure cylinder oil narrowed short time displacement is large it is often said that the theoretical value is low voltage large displacement data
First of all I want to say the first floor, still say oneself is the couplet, see your own answer to throw not to be ashamed of? Second is on the second floor, the second floor of the theory is also good, is to add is that the low pressure large displacement, high pressure small displacement of the main reason is the low pressure pump pump pressure oil from the main pumping rod chamber into the oil cylinder, high pressure from the rodless cavity into. Due to the main cylinder rod cavity side has a coarser piston rod, the case in the main pump delivery pressure oil from the rod chamber into the main pumping oil cylinder is better than the rodless cavity driven into the main pumping oil cylinder concrete cylinder piston stroke, a corresponding low pressure is bigger than high pressure displacement, but high pressure pump than the discharging mouth of the low pressure pumping pressure, have not clear can contact me again
