Excavator actuator control system 1) automatic two-speed travel system automatic two-speed travel system is only in walking speed switch is in the second speed position when has this feature. In this case, the signal to travel two-speed solenoid valve commutation; at the same time, by the second speed opportunistic clothes cylinder so that the motor is running second speed position, speed walking excavator. The control valve also choose to walk by the effects of stress, when a large load uphill, and control the selector valve to the side of a commutation speed; second speed hydraulic servo control unloading, make travel motor automatically to a Track speed position conversion price mini excavator driving force increases. Excavator walking on flat ground and downhill walking and other working conditions, running resistance is smaller, the control back to the selector valve for the second speed servo cylinder action, walking motor speed is automatically returned to the second position on the domestic mini-excavators Price, the control machine speed walking. 2) rotating turntable turntable rotating movement preventing mechanism movement preventing means is stopped after excavator turret rotation to eliminate the shaking mechanism works: Rotary horse had stopped the process, both sides of the valve to prevent reverse pressure by unloading mini excavator price, compress the spring. Because the left and right pressure equal, reversing valve is not reversing. After the swing motor stopped B port side pressure ratio A port side is high, the rotary motor counter-productive force, the rotary motor shaking, then the A port side pressure higher than the B port side of the reversing valve to stress. Since the valve orifice, time lag, the spool move to the right so that the A port and the B port Unicom, the same pressure. Therefore, only one turntable rotation shake it. 3) hydraulic system work equipment control system hydraulic excavator has six actuators - the left and right travel motors, to convey station rotary motor, boom cylinder, arm cylinder and bucket cylinder.泰安嘉 and Heavy Machinery Co., Ltd. of the engine control system consists of the appearance characteristic of the diesel engine shows that the diesel engine is approximately constant torque adjusting prices for small and medium excavators, the output power changes represent changes in speed, but does not substantially change the output torque. Throttle opening increases (or decreases), the diesel engine output power increases (or decreases), the output torque is essentially the same, so the engine speed increases (or decreases), that is, different throttle opening corresponding to different diesel speed. Thus, the purpose of the diesel engine control is through control of the throttle opening is adjusted to achieve the engine speed. Currently used in the hydraulic excavator diesel engine electronic control unit power optimization systems, automatic idling devices, electronic speed control, electronic throttle control system.泰安嘉 and Heavy Machinery Co., Ltd.-made mini-excavators and heavy price _ Kerry (certified) _ Changzhi mini excavator price offered by 泰安嘉 and Heavy Machinery Co., Ltd ..
