construction earthmover

Check the torque converter normal; construction earthmover loosen the screw speed exhaust fine filter on the discharge of oil found in a bubble, and the long endless row. Analysts believe that if the place into the air, cold, heat engine intake should result in a cold state machine is now working properly, it can be concluded Low oil seals in good condition. The high pressure heat engine intake causing the machine can not walk, you should spend a large low-pressure vacuum caused by the oil.Further examination revealed that between the suction port and suction strainer hose has been deflated, into the oil poor, hydraulic dozer manufacturers the higher the engine speed, the more serious this phenomenon. The reason is that the inner hose is aging peeling, peeling after temperature rise into the oil passage blockage, causing a vacuum through the large.

power shift hydraulic dozer

the performance of the pump system to reduce torque variable speed hydraulic oil is mainly provided by a variable speed pump and reduce pump performance, lack of fuel supply system, power shift hydraulic dozer causing hydraulic oil can not fully play the role of the media, while not adequately lubricate all moving parts, so that the friction between the moving parts increases, a corresponding increase in the mechanical heat, but less than the predetermined number of hydraulic oil in the circulation can not be taken away excessive heat,lower price dozer resulting in high oil temperature.

hydrostatically driven crawler tractor

swamp crawler bulldozer with blade lack of fuel tank systems bulldozer working conditions are generally more severe, workplaces large and bumpy slope, fuel shortage will pump cavitation phenomenon occurs, the normal fuel consumption can not supply the hydraulic system, so always check the bulldozer The oil level is necessary. Bulldozers can be placed on flat ground, hydrostatically driven crawler tractor check the oil level on the dipstick, the oil level should achieve the required mark.

High Efficiency Crawler Bulldozer

shift control valve is faulty bulldozer hydraulic system is quite delicate, especially the various hydraulic control valves, valve gear is one of them. Poor cleanliness of hydraulic oil or using improper maintenance,High Efficiency Crawler Bulldozer  will result in the shift valve malfunction, so inadequate fuel supply converter. Especially 160 bulldozer, variable speed torque converter only way hydraulic oil systems, there is a huge shift valve failure impact on the system. In general, the safety valve stuck in the valve gear is the most direct and common form of failure. You can check the shift valve, power shift hydraulic bulldozers the oil inlet pressure (pressure relief valve inlet pressure that speed for 2.5MPa; pressure relief valve outlet pressure converter that between 0.5-0.9MPa), shift valve fails mainly the system pressure is low; the shift valve safety valve should be removed and cleaned, to troubleshoot.

Hill pushed 900 horsepower bulldozer show "Made in China" style

Through two days of inspection preparedness work,swamp crawler bulldozer with blade Shantui service team a comprehensive understanding of the equipment in use and solve the shift pressure is low and some other small problems and improve the stability of the vehicle system operation. Request of the user, Shantui service inspection team and working hydraulic systems of its holdings of other brands of equipment, troubleshoot problems and solve them. The entire inspection process, the user of Shantui Services Group cautious attitude and professional skills thumbs up, said he was very recognition, hope Shantui service personnel to continue to provide assistance and in SD90-5 Mechanical Crawler bulldozer post-maintenance aspect guidance.

Widely used bulldozers

hydraulic bulldozers with traditional Mechanical Crawler bulldozer, as in the national economy and building the country, occupy an important position . It is widely used in railway construction, highway construction, airport construction, water conservancy projects, housing construction, municipal engineering, port construction, mining engineering, underground engineering, military engineering and other construction projects, our founding fifty years of socialist construction practice fully explain, if not a lot of quality bulldozer, it is impossible to complete the country's high-speed high-quality construction projects. As for the sparsely populated, narrow Face, poor working conditions, alpine desert, strict quality requirements of engineering projects, not quality Mechanical Transmission Bulldozer Is absolutely impossible to complete the task.

Mechanical Transmission dozer

Hydraulic technology based on the application Full hydraulic dozer is a typical field of construction machinery in the earthwork construction equipment,A tractor is installed in front of the dozer loaded road construction machinery, for bulldozing, leveling the building venues. For example, in the construction of road construction, the bulldozers can complete the process of subgrade, roadside soil lateral Tim building height of not more than one meter of embankment along the centerline of the road towards the shovel to dig transferred, Mechanical Transmission dozer transported soil roadbed Watian engineering, taking the mountain construction of part - cut soil subgrade. In addition, the bulldozer can be used for leveling the ground and accumulation of loose materials, removal of obstructions and other operations within the lot.

Bulldozer cache design

Each core has a 64KB Track Dozer  level data cache, 64KB instruction cache, 32-entry fully associative data cache page table (DATA TLB), complete out of order load / save unit, which can in each clock cycle Loading 128 within two or load a 128-bit instruction. Each module is equipped with 2MB 16 way associative secondary cache, 124-entry two page table cache can handle instructions and data requests. Bulldozer supports up to 23 secondary cache misses, memory system for maintaining consistency. Finally, all modules with a bulldozer processor core shared 8MB 64 way associative cache levels. Bulldozer significantly improves power management technology, support CC6 power state at the core level, at the module level can be supported by the secondary cache CC6 power gating (Power Gating). With power gating, idle core can be almost completely off, giving the other core leaving more space to accelerate. Full hydraulic crawler bulldozer has three modes of operation: acceleration frequency of the original preset reference frequency, acceleration frequencies all the core open, half of the core open. All core acceleration: If the excess thermal design power (TDP) space allows, bulldozers can be accelerated for all the core

Architecture Analysis

Embarking on designing the next generation x 86 processor cores, when, AMD's engineers considered necessary to achieve the core area of power consumption and optimization, and development of PC applications also allow engineers must find a new path, it is possible between different cores maximize peak bandwidth, and through sharing module to take advantage of every square millimeter of the core area. The end result is the ability to efficiently optimize the dual-core modular resources. Integer pipeline, a data caching frequently used features in each core has a separate functional units, prefetch, decode,drive bulldozers， floating-point pipeline, the secondary cache and other functional units in the two core in shared use. This design allows each core can use when you need a larger, higher-performance functional unit than each core has its own small independent functional units more economical core area. This design concept is a direct manifestation of the core area. Eight-core Bulldozer is AMD manufactured the history of the largest chip integrates approximately 1.2 billion transistors, but the application, the core area through the rational allocation of functional units,construction earthmover as well as the new 32nm SOI process is controlled only to 315 mm2, more than six-core, 45nm process Phenom II X6 9 percent smaller than the quad-core, 32nm HKMG technology Sandy Bridge only 46% larger

Information about high drive bulldozer

Front and rear guide wheel high driven bulldozers drive sprocket and walking system triangular arrangement, the drive sprocket set away from the high ground, to avoid the traditional bulldozer contact with the ground due to the drive sprocket suffered a direct impact load, so that the drive significantly improve the life of the system. mechanically driven bulldozer is doing the best global Caterpillar, currently the only Vision Engineering technology is mature and has formed a production. Vision Engineering since 1993 to develop and produce high drive bulldozer, 2003 batch to domestic and foreign markets, there are SD7 (230HP), SD8B (320HP), SD9 (430HP) 3 major product lines
