The reliability of the whole system is also much higher as well as the components’ life is prolonged greatly.This isconvenient for judgeing and removing trouble.采用双泵、双回路开式液压系统，主泵送油路和S阀摆动油路相互独立，使系统简单，元件寿命延长，可靠性更高，并便于故障判断和排除。
Large valve changing direction, makes the main pumping loop quick response, small leakage, good stability,high reliability and high resist contaminative capability.主泵送油路采用大通径阀换向，响应快,内泄漏小,稳定性好,可靠性高,耐污染能力高。
Hydraulic system has safe relief protection,at the same time,when the system pressure is over, the main oil pump cutting device makes itself be protected reliably.泵送液压系统具有安全溢流保护，同时，主泵还具备系统超压时，油泵压力自动切断截流装置，使主泵获得多级可靠保护。
Distributing hydraulic circuit adopts constant pressure pump, which can provide strong distributing pressure and economic energy control.摆动油路采用恒压泵供油，摆动力大又具备节能功能。
Cone sealing of all pipes make the pipe joints seal reliably.所有管路均采用锥面密封，管路接头密封可靠。
The electrimotion high-low pressure switch adopting cartridge valve of reduces the trouble of dismantling and installing the oil pipe.采用插装阀电动高低压转换，免去拆、装油管的麻烦。
Adopt emulsification technology of initiative and passivity recovery integration.采用了主动防御和被动防御相结合的综合防乳化技术。
2.2 Electric control system电控系统The outstanding features of the truck-mounted concrete line pump are advanced technology, simpleness and high reliability.中联车载式混凝土泵车电控系统的突出特点是技术先进、简单、可靠性高。
The reliability of industry control is higher than PLC(programmable control). It uses fewer auxiliary relays, father reducing the quantities of the electric element.该泵使用带总线的工业控制器作为控制核心，比之以前同类产品用的PLC（可编程控制器），其可靠性更高，功能更强大；由于其输出触点有更大的输出功率，比PLC系统可以使用更少的中间继电器等分离元件，进一步减少了电器元件的使用数目及接线数量，提升了电控系统可靠性。
The main electric control elements from German and French ensure the elements reliability.主要电气控制元件均采用德国易福门、海拉、巴鲁夫和法国施耐德公司等原装进口件，保证了元件的可靠性。
Compared with domestic product, the electric control system is simplest, the element quantity is fewest and its reliability is highest.与国內同类产品比较，电控系统最简单，采用元器件数量最少，可靠性最高。
The wire and wireless remote equipment is convenient for operation far away.配有有线或无线遥控装置，方便远距离操作。
After the automatical pumping stops, the diesel engine’s rotate speed declines to idle speed automatically to save oil.自动泵送停止后，柴油机的转速会自动降为怠速，以节省油料。
Adopting proximity switch in hydraulic cylinder can realize changing direction with non-touch, which ensures that the direction can be changed reliably.采用油缸内接近开关非接触换向，确保换向可靠。
The direction and stroke control function makes the oil quantity of the main pumping cylinder adjusted automatically, thereby the optimal control of pumping can be realized.带有换向行程优化控制功能，能根据主缸行程自动调节主缸的进油量，从而实现泵送最优化控制。
The GPS function can monitor and control the equipment position and running status.带有GPS功能（选配），可以远程监控设备位置以及运行状况。
The touch screen can check the equipment run status,imput and output state and alarm display.带有触摸屏，可以随时查看设备运行、输入输出状态和实时报警显示，并可方便设置系统各项参数。
The high efficiency and reliable double-signal control system, which is installed main and complement signal check sensor, ensures that the truck-mounted concrete line pump has good ability of concrete suction and high efficiency.采用高效可靠的双信号控制系统，即安装有主辅两套信号检测传感器，可保证泵送油缸满行程工作,从而确保了车载泵具有良好的吸料性，实现了泵送的高效率。
2.3Mechanical system机械系统The design of hopper and S valve and so on adopt Ｉ－DEAS software to caculate, the hopper and S valve have good rigidity to avoid the phenomenon of hopper distortion and S valve breakage.料斗、S阀等关键受力元件的设计，采用Ｉ－DEAS软件对其受力状态、结构刚度、应力集中状况进行了细分网格的有限元计算，设计出的料斗、S阀结构刚度好、工艺性佳，避免了同类产品高层输送时料斗变形及S阀断轴现象。
The agitator have unique form, which separates the hydraulic motor from agitator bearing pedestal.At the same time, adopting large displacement motor ensures that the agitator moment is big enough.搅拌机构采用独特的结构形式，将液压马达与搅拌轴承座完全隔离，即使搅拌密封磨损漏浆，也不至于影响液压马达。
同时，采用大排量马达，确保搅拌力矩足够大，即使料况差的情况下也能正常搅拌不被卡死。
Make sure the pumping is good and decline the phenomenon of pipe jam, the spectacles wear plate and cutting ring should be useed in lower abrasion. ZOOMLION’s spectacles wear plate and cutting ring use high wear material, making the components’ life prolonged greatly.车载式混凝土泵车的眼睛板，切割环应该在低磨损下使用，才能够确实保证良好的泵送状态，降低堵管现象的发生。
