Liugong CLG509A paver can not move in many parts
Fault phenomenon: Liugong CLG509A leveling, big arm, hopper can not move, other parts are normal
Analysis: this phenomenon in the mechanical aspects of the problem can not be considered, the key is the hydraulic aspects
Electrical aspects: A, leveling switch is not reset, resulting in leveling cylinder always at the dead center, so that the priority diverter valve overflow (this phenomenon can see whether the leveling is at the highest and lowest point to determine)
Hydraulic aspects: A, manual reversing valve located in the track tensioning position; B, leveling valve spool is not stuck in the middle (this phenomenon can see whether the leveling is at the highest and lowest point to judge); C, priority shunt valve damage; D, work pump damage (pump shaft broken or internal leakage)
Look at the performance characteristics of Liugong CLG509A paver:
CLG509A paver, unique four closed loop (paving forward, backward, moving forward, backward) mode, paving high stability, straight line paving performance is good, smooth steering performance is good
Double throttle handle operation, increased convenience; with lock function, prevent the construction speed down; the radiator suction surface increases the filter, avoid the small stone particles being sucked into the heat sink, improve the heat dissipation performance; at the same time, there are advanced electrical system, load sensing proportion of soft material, stability control to reduce segregation; the core components are reliable and durable.
Liugong CLG509A paver is widely used in national roads, parking lots, airports and other road construction projects at the grass-roots and surface construction, Liugong paver for China's road construction has made a positive contribution
Dongfeng Cummins 6CTA8.3-C195 engine Liugong CLG509A paver is equipped with the power up to 145kW, and has the characteristics of large torque backup and anti load capability, to ensure stable and reliable in working process. At the same time, the product adopts 330L diesel fuel tank, fuel tank compared to common paver 250L volume to a greater extent extend the time of operation, which makes the efficient and reliable in operation. In addition, the main mechanism of CLG509A paver are hydraulic about independent drive system, advanced automatic control system can be used to ensure the stability of the paving process, and the factors affecting the accuracy of spreading to a minimum, to ensure a high stand the quality of the product and shop. Walking, spiral, vibration and impact load of large hydraulic pump with the international well-known brand heavy duty series variable piston pump, can improve the bearing capacity of the system, further to stand The continuity and stability of the paving process are effectively guaranteed, greatly reducing equipment heating and improving work efficiency
CLG509A paver leveling, walking, spiral material, scraper feeding are using closed-loop feedback control principle, the detection of machine condition sensor feedback to the control element, so as to achieve the accurate automatic control. The computer control of the automatic centralized lubrication system, the machine parts are fully automatic lubrication, but also the greatest degree reduce the maintenance workload of the paver, saving energy of users in the machine maintenance. In addition to the material receiving machine height is 592mm, the extension of the frame push roller and aniseed 20mm thick material receiving hopper bottom plate will make operation more convenient, has the patent technology of crawler hydraulic tensioning system in equipment after the start automatic tension, to ensure the stability of the equipment when walking, the driver through the CLG509A built-in pressure detection device is adjusted according to the need, in order to improve the life of the track, and then improve the whole life.
More reassuring is that the CLG509A paver in the selection of accessories, the continuation of the Liugong only boutique concept, all matching international first-class brand of hydraulic and electrical components, reducer, bearings, the same type of paver with higher quality and the highest reliability reflects Liu "customer oriented, people-oriented, quality achievements in the future, cooperation and create value" concept of values, allowing customers to buy.
With the highway network formation and construction technology continues to improve, China paver will be constantly updated technology and usher in the development of healthy and stable situation, Liugong has CLG509A as the representative of the domestic paver will eventually become a force in the highway construction in our country. And Liugong, will continue to work on the machine. Study on the spreading, guide and promote China's paver and road machinery industry development and technological progress.
