With the advanced technology of electric motor concrete pump in the world, Oriental integrates with the improved experience and product concept to meet the requirement of high efficiency and low consumption of modern construction. The hydraulic system adopts double-pump double-circuit, and the pumping unit adopts the original high-pressure and large displacement variable oil pump. The product is widely used in urban construction, water conservancy, and tunnel construction.
Hydraulic oil pump: Germany Rexroth or Japan Kawasaki are adjusted.
Electric Mortor: Domestic famous brands.
The main power could be adjusted by the users.
2.Electronic control system
Japan Mitsubishi Programmable Logic Controller (PLC) electronic control system.Main electric elements are imported original Schneider, Siemens, OMRON, LG etc.The control mode: manual operation and wireless remote controlHumanity and intelligent electronic control system optimizes the person-machine interface.8-digital pumping time accumulation timer provides exact data for the user, Automatic anti-pump function and optimized program design. Automatic trouble monitoring function.
The unique open hydraulic system and hydraulic cushion technology contribute to the smaller exchange impact and less heat of the system. Meanwhile, with the famous brand of main pump and hydraulic valve, the safety and reliability of the concrete pump are guaranteed.
Pumping displacement variable adjustment: Change the pumping displacement according to the construction to meet the requirement of the condition.Reducing design of the hopper could release the reducing pressure of the concrete into the delivery pipe maximally, and prolong the service life of the S pipe outlet.
The patented central automatic lubrication system comes with a piston grease-pump, features high pressure and reliability, which can realize automatic lubrication of piston. The filters at the outlet and the inlet of oil ports as double protections guarantee the system reliability.
Compulsory air-cooled heat exchanger keeps the temperature of the hydraulic oil below 60℃,that ensures the whole hydraulic system works at normal status.
