Used Mini excavator mini excavator price price _ _ Ka Guangdong and Heavy

 Small wheeled excavator bucket capacity 0.3 ~ 0.4m3, the structure is simple, inexpensive, and its hydraulic system is relatively simple: about 20MPa pressure gear pump hydraulic oil through the pipeline to the multi-valve, valve control each cylinder actuator moves along the loop system hydraulic oil back into the tank. Cool down the entire hydraulic system, thanks to a put back on the road in the area of ??250mm × 250mm air-cooled radiator is completed. Most mini excavator price, often appear weak or no action motion phenomenon aircraft summer use. The reason is that the hydraulic oil temperature is too high. Consider the overall cost-effective and practical effect, according to the author many years of experience, in the vicinity of the oil port of the gear pump to install a 600mm × 450mm × 250mm tank, and a number of built-in serpentine, connected into the pipeline route; the cabinet above the weld 10 a diameter of 25mm seamless pipe, water cooling water tank to reduce oil purposes. After testing, the effect is good, a better solution to the problem does not work excavator hot weather. Hydraulic excavator machine control system features a hydraulic excavator as a mainstream excavators, currently one of the major development of electro-hydraulic steering hydraulic excavator, a hydraulic excavator whose aim is to achieve full automation, the study of people on the hydraulic excavator, electro-hydraulic control system gradually transferred to the direction that the excavator from the traditional to the progressive development of levering hydraulically operated, pneumatic operated, electric steering, hydraulic servo steering, radio control, electro-hydraulic proportional direct manipulation and computer manipulation. So the price of mini-excavators, hydraulic integration of domestic excavator mini excavator price study, focused on the hydraulic excavator control system. Hydraulic excavator control system is a dynamic system of the engine, hydraulic pumps, multi-valve and actuators (hydraulic cylinders, hydraulic motors) and so constituted control system. Press the control functions can be divided into position control system, speed control system and force (or pressure) control system; by the control element, can be divided into the engine control system, hydraulic control system, multi-valve control system, the actuator control systems and machine control systems. Currently, the hydraulic excavator control system has been developed to complex control system.泰安嘉 and Heavy Machinery Co., Ltd., Guangdong used mini excavator mini excavator price price _ _ Kerry and provided by 泰安嘉 Heavy and Heavy Machinery Co., Ltd ..泰安嘉 and Heavy Machinery Co., Ltd.
