Kind.
Additionally, the present invention also provides a kind of pumping system, including master cylinder and conveying cylinder；The master cylinder is provided with main oil
Cylinder piston and the main oil cylinder piston bar being connected with the main oil cylinder piston；Arrange above-mentioned arbitrary concrete to live in the conveying cylinder
Plug, the concrete piston are connected with the main oil cylinder piston bar.
Additionally, the present invention also provides a kind of concrete pump, including above-mentioned arbitrary pumping system.
Concrete piston and pumping system and concrete pump that the present invention is provided, due to inlaying on seal or/and guide ring
Have kollag, can play self-lubricating effect, and form solid lubricant film between frictional contact surface, reduce seal or/and
The directly contact and friction of guide ring and conveying cylinder, so as to without the need for relying on outside supply reduce the seal of concrete piston, lead
Fretting wear between Xiang Huanyu conveying cylinder, improves the service life of concrete piston and conveying cylinder.Input in extraneous lubricant grease
During discontinuous or interruption, preferable lubricant effect is still kept, it is to avoid the appearance of unlubricated and dry grinding operating mode.Additionally, extraneous lubrication
Grease can be changed to interruption manually by automatically continuously addition and add, and reduce use cost, simplify lubrication configuration.
