Taian Jia and JH60 excavator Main features: high performance super-configuration imported configuration domestic prices · domestic famous engine, strong power, small hydraulic excavators prices to meet the requirements of efficient operation. · Accurate matching design with advanced energy-saving control of the machine and less fuel consumption. · Low emissions meet Euro Ⅱ standards. · New cooling fan and a large muffler used to make the machine quieter; * Using the most advanced technology turbo mini excavator price, enhanced machine plateau adaptability; Unique funnel-type fan cover, greatly enhance the ability of the engine intake air flow and cooling system to ensure continuous and efficient machine operation. · Advanced hydraulic system · High-end configuration: the main pump, main valve, swing motor, travel motor, cylinder, pilot operated valves and other components are used internationally renowned brands, ensuring the quality of the product. · Integrate the latest research results, reduce energy consumption, improved design mini excavator price, faster response. · Strong and precise swing control: Improved vibration absorption properties, make sure to stop turning movement more precise and smooth; by increasing the torque reserve, to provide a more robust rotary machine capacity; · cylinder with buffer function: the boom cylinder and stick cylinders, bucket cylinder design a buffer can reduce vibration and shock of the machine, reduce noise and extend cylinder life; · double pump confluence technology: the main valve to increase the supply of the boom, arm and bucket cylinders each flow, improve the operating speed. Taian Jia and Heavy Machinery Co., Ltd. excavator actuator control system 1) automatic two-speed travel system, automatic two-speed travel system is only at walking speed in two-speed switch position when has this feature. At this point, the signal to travel two-speed solenoid valve commutation; at the same time, by two-speed motor waiting to serve in the two cylinders so that walking speed position, speed walking excavator. Also used mini excavator price, 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, so walking motor automatically converted to a speed position, the driving force increases. Excavator on the ground when walking downhill and walking and working conditions, running resistance becomes 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, the control unit High-speed walking. 2) rotating turntable rotating turntable shake shake prevention mechanism to prevent the institution after the excavator turret rotation stops eliminate shaking mechanism works: turning the horse had stopped the process, both sides of the valve to prevent reverse pressure by unloading spring compression. Since the left and right pressure is equal to the reversing valve not change. After turning the motor stops B port side of high pressure than the A port side of the rotary motor counter-force, the rotary motor shaking, then the A port side pressure than the B port side of high pressure to produce anti-reversing valve. Since the valve orifice, a time lag, the spool moves 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 - left and right travel motors, rotary motors convey Taiwan, boom cylinder, arm cylinder, bucket cylinder.泰安嘉 and Heavy Machinery Co., Ltd.
