Product introduction: Rexroth for excavators

Guide: on October 16, 2007, at the China International Construction Machinery Exhibition opened in Beijing, Bosch Rexroth, the world's leading industrial technology supplier, demonstrated a variety of innovative construction machinery control technologies. One of them is the M valve group applied to forward control. It ensures that the system has high efficiency, multi

its integral compact design and positive control technology not only cover packaging material suppliers, express delivery enterprises, e-commerce platforms and businesses, but also provide the best energy-saving platform for 2 to solve the problems of starting the refrigerator when the temperature in the studio is high, and the operation of standard excavators above 0 tons, while greatly simplifying the pipeline layout required by excavator manufacturers. Compared with negative flow control technology, M9 control valve provides faster dynamic response, higher stability, more perfect function and better control that SAE China is doing in this field

various compound actions are often required in the use of excavators. The circuit design of M enables each main actuator to have an independent oil pump for oil supply. The independent oil pump oil supply circuit makes it possible to quickly operate multiple actuators under different load pressures, and energy saving can be achieved even in staggered operation. At the same time, the confluence circuit of the pump ensures that the maximum speed required by the excavator can be reached. The new forward control technology and the medium optimized flow passage design minimize the no-load loss. Another advantage is that the oil pump does not control the energy consumption at any working swing angle

m9 adopts a compact overall design, which can realize simple and economical pipe laying with low △ p value even if the installation space is limited. The working oil ports of the boom, stick, bucket, swing and travel mechanisms are located on the front of the valve body; An additional functional linkage, such as for hydraulic hammers, has been integrated into the valve block. This has become the standard configuration of the valve. The oil inlet, return port and cooler oil port are located on the opposite side of the control valve. The factory can expand the M9 control valve union with positive control system according to market requirements. Rexroth's RC controller and bodas software system manage all kinds of oil pumps and control valves - whether using pressure sensors or proportional reducing valves integrated on M9. In this way, we can gradually transition to the full electro-hydraulic excavator control system without making major design changes
