Excavator hammer maintenance due hammers very poor working conditions, proper maintenance can reduce machine failure, prolong life of the machine, in addition to timely maintenance of the host, we must also pay attention to the following points: (1) visual inspection . Inspection of the bolts are loose; the connecting pin for excessive wear; check Rod bushing gap to its normal sized hydraulic excavators, whether there is oil leaking therebetween, indicating low pressure seal is damaged, replace to professionals. (2) lubrication. Work equipment lubrication point, before the job and each successive 2 ~ 3h after operation, and should be lubricated. (3) the replacement of the hydraulic oil. Hydraulic oil change while differences due to different working environment, a simple way to determine the quality of the oil is to observe the color of oil, when oil deterioration in the situation is extremely serious, the oil should be let go, and cleaning fuel tank, and then inject the new oil filter. (4) the main breaker as set contains precision components hydraulic circulatory system, usually without special equipment factory Do not disassemble, repair commission must be made.泰安嘉 and Heavy Machinery Co., Ltd. hydraulic excavator condition monitoring and troubleshooting system hydraulic excavator condition monitoring and troubleshooting system plays an important role in improving maintenance mode, to ensure safe operation and eliminate accidents and so on. The system currently has two forms: one is a diagnostic computer - handheld terminal insertion system in the form of small and medium sized excavator manufacturers, such as Japan's Hitachi Construction Machinery Company Dr.EX fault diagnosis system; the other is random Installation of the system, such as Germany's O & K condition control system (BCS), which pioneered the use of satellite communications technology, each station job Excavator residence status and fault by the onboard transmitter to the synchronous satellite launch small and medium mining machine, and then by the transponder on the satellite sent back service management center, the functioning of the various real-time display on the computer screen excavator management center. Automatic excavation control system using a laser transmitter automatic excavation control system, the basic principle is to set up a rotary laser transmitter at the construction site, it can control the number of excavators in the same datum requested operation. Equipped with a laser receiver on the excavator, on which there are three optical target - upper and lower target and the reference light optical target. When the laser beam emitted from the laser emitter exactly hit the target reference light wheeled mini excavator price, working equipment excavator working surface is maintained at an ideal operational requirements. If the change in external factors make excavator working device deviates from the ideal working surface required, the laser beam is incident on the glazing or target or target shooting in the next light, the operation means has produced the phenomenon of deviation. Then polish the target or targets will light under the light signal into an electronic command signal is provided on the excavator driven diverter valve action, so as to control the flow of hydraulic oil, so excavator working device required to return to the ideal Face on the job. Using a laser transmitter automatic excavation control system can greatly reduce the labor intensity of the driver, and get a better quality of excavation work.泰安嘉 and Heavy Machinery Co., manufacturer of small and medium excavators, Kerry and Heavy Industries (certified), Changzhi sized excavators offered by 泰安嘉 and Heavy Machinery Co., Ltd ..
