Main technical feature

1. Hydraulic system

• Doubleopen hydraulic loops (pumping hydraulic circuit isindependent ofdistributing 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 isconvenient for judgeing and removing trouble.
• Large valve changing direction, makes the main pumping loop quick response, small leakage, good stability,highreliability and high resist contaminative capability.

• 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.

• Distributing hydraulic circuit adoptsconstant pressure pump, which can provide strong distributing pressure andeconomic energy control.

• Cone sealing of all pipes make the pipe joints seal reliably.

• The  high-low pressure switch adoptingcartridge valve of reduces the trouble of dismantling and installing the oil pipe.

• Adoptemulsification technology of initiative and passivity recovery integration.

2. Electric control system

• Compared withdomestic product, the electric control system is simplest, the element quantity is fewest and itsreliability is highest.
• The wire remote equipment is convenient for operation far away.
• Adopting proximity switch in hydraulic cylinder can realize changing direction with non-touch, which ensures that the direction can be changed reliably.

3. Mechanical system

• 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 thephenomenon of hopper distortion and S valve breakage.
• The agitator have unique form, which separates the hydraulic motor from agitatorbearing pedestal.At the same time, adopting largedisplacement motor ensures that the agitator moment is big enough.
• Make sure the pumping is good and decline the phenomenon of pipe jam, thespectacles wear plate andcutting ring should be used in lower abrasion.  Xinsai'sspectacles wear plate andcutting ring use high wear material, making thecomponents' life prolonged greatly.

4. Lubrication system

       Thehydraulic circuit will take high oil into double distributor,and then the lubricating part can             obtain hydraulic oil.It ensures the lubrication of the concrete cylinder's piston and other parts           and prolongs the life of piston and other sealing.

5. Cooling system

      The radiator equipment makes the working oil temperature of hydraulic system below 70ºC             and  makes the machine in normal status.
