Excavator tips overview 1, the operating technology first to confirm the situation around. When the rotation job, around obstacles, terrain to be aware of safe operation; when the job of domestic mini excavators Which is good, to confirm the longitudinal direction of the crawler mini excavator, avoid tipping or impact; try not to end Transmission face excavation direction, or easy to damage the travel motors or hoses; the job, to ensure that the left and right track in full contact with the ground much money to buy a mini excavator, improve the dynamic stability of the machine. 2, the effective mining methods when the bucket cylinder and linkage between, the arm cylinder and the arm each 90 degrees, the maximum digging force; bucket bucket teeth and the ground to maintain a 30 degree angle, the best cut in the soil digging force least resistance; when digging arm, should ensure arm angle between 30 degrees in the angle range of 45 degrees from the front to the back. Using both boom and bucket, can improve the efficiency of mining. 3, the use of bucket digging rock rock excavation machine would cause greater damage, shall be avoided; must excavation, should be based on the rock of crack direction to adjust the position of the body, smooth shovel into the bucket, dig; to fight inserted into crevices in the tooth, mining (bucket should carefully slip teeth) with arm and bucket digging force; not broken rock, re-use should be broken bucket digging. 4, trimmed flat slope level jobs when the machine flat on the ground, preventing the body shaking, motor coordination to grasp the boom and arm, the control of both the speed of the plane trimmed crucial. 5, the loading operation of the body should be in the position of the horizontal stabilizer, or unloading is difficult to accurately control the rotation, thereby extending the operating cycle time; the body and the truck to keep an appropriate distance, to prevent rotation of 180 degrees when the rear body and truck collide; try turning counterclockwise On installation, this vision, high working efficiency, and to correctly grasp the rotation angle, in order to reduce the time for rotation; excavator truck position lower than the forest in order to shorten the boom lifting time, and the line of sight is good; the first load of sand , gravel, then place large stones, thus reducing the impact on the wagons. 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 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 Conversion speed position, the 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, the control unit High-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 spring compression. 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 domestic small excavator price, 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. used mini excavators, Kerry and Heavy Industries (certified), Texas mini-excavators by 泰安嘉 and Heavy Machinery Co., Ltd ..
