Concrete mixer is a kind of transport and mixing concrete dual function of special purpose vehicles. Regardless of the vehicle on the highway at high speed or in traffic lights stay in front of the drum must maintain a consistent speed , or in the long-distance transport of concrete occurs when condensation , stratification and segregation phenomena , which greatly affect the quality of concrete . However , in the transport process, the car started or uphill , the engine speed increases , fuel pump that increases in proportion to the amount of the rotational speed of the mixing tube will also be increased accordingly . In this way , not only increases the engine's power consumption , accelerate the wear of the mixing tube , concrete mixer affecting driving performance , but also not uniform mixing of concrete , reduce the quality of concrete . With modern construction of concrete quality requirements continue to increase , how to ensure that within the specified time will be delivered concrete mixing plant from the construction site , and to ensure the same quality of concrete , is the next generation concrete mixer face new challenges.

In response to these problems , Eaton put forward a set of advanced mixer drum constant speed control solutions.

The system to ensure quality, while stirring , to improve the vehicle's power , fuel costs and vehicle emissions are also reduced. Drum constant speed control program integrates advanced technology and sophisticated electronic logic control algorithms, and combines the EFI engine CAN bus capability. The main principle is: according to the control requirements and the control panel commands the system through advanced logic operation, the output current electrically controlled proportional valve , thereby controlling the pump displacement to achieve the roller constant , or by leaving the engine speed control constant speed mixer drum . Drum constant speed control system mainly consists of the following components : controller , the main control panel , wireless control panel , proportional hydraulic pumps, hydraulic motors, and so on. Through the main control panel switch button , you can achieve mixer scene and wireless remote control.

Drum constant speed control system mainly consists of seven operating modes: automatic feed, automatic discharge , the driver controls the throttle discharge , constant speed , stop , emergency stop and emergency operating mode. In a different operating mode , the control system adjusts the pump displacement ratio and engine speed to achieve constant speed mixing tube .
