Hydraulic system液压系统

Double open hydraulic loops (pumping hydraulic circuit is independent of

distributing hydraulic circuit) with two pumps, makes the whole hydraulic system

much simpler. The reliability of the whole system is also much higher as well as the components’ life is prolonged greatly. This is convenient 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。

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.

与国内同类产品比较，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。
