The cause of discoloration excavator cylinder 1, the hydraulic system has high temperatures, the piston rod in the work at high temperatures (especially in the cold season) frequently in contact with a low temperature environment (temperature momentary dip); 2, in the replacement of the maintenance period Non-brand excavators hydraulic oil, piston rod discoloration usually within just a few days of the oil-for-End will appear. The reason is an extreme pressure of hydraulic oil in different quality and performance of anti-wear additives; 3, the piston rod plating process due to the temperature control is uneven, resulting in plating layer surface cracks appeared in the late work. If you look at the rod surface with a high-expansion magnifying glass, you can see the irregular hairline cracks. 4, the fuel tank is additive blue seal and hydraulic oil within the cylinder rod attachment at high temperatures caused by blackening is due to lower overspray Cup disabilities (ie wear sleeve) out of lead additives within the high temperature in the cylinder is attached rod. Hydraulic oil is usually caused by too much, and this phenomenon occurred in the use of more bucket cylinder of the first half, we recommend regular cleaning of the radiator portion of the dust, to ensure the cooling effect. Hydraulic systems 泰安嘉 and Heavy Machinery Co. excavator attachment hydraulic excavator control system has six actuators - the left and right travel motors, hydraulic rotary motors convey station mini excavator, boom cylinder, arm cylinder , bucket cylinder. In order to improve productivity and save excavator mini excavator factory direct energy consumption, digging excavator loading process, the need for rotary motors and three hydraulic cylinders coordinated action mini excavator, namely working device control system should have the following three functions : (1) control machine control functions. Bucket along horizontal or at an angle with the horizontal linear motion, circular motion; arbitrary trajectory. (2) loading and digging function. Complete full bucket elevator, rotating and unloading. In this process, the requirements of the bucket relative to the ground plane begin to ascend while maintaining the angle to prevent the bucket material scattered in the promotion process. (3) The reset control function. After uninstalling through the boom, four movements of the arm, bucket and swing, etc. linkage, the bucket back to the start of mining locations. Control in the form above organic liquid excavator working device control and computer control in two ways.泰安嘉 and Heavy Machinery Co., Ltd. manufacturers offer mini-excavators, mini-excavators, Jiangxi, Kerry and Heavy Industries and Heavy Machinery Co., Ltd. by the 泰安嘉.泰安嘉 and Heavy Machinery Co., Ltd.
