Q:How do excavators do?
Look at your savvy! Learn one day, one year will not learn, and understand! If you want to learn, study hard, you can do a simple job in a month or so! In fact, the real master is not good in this aspect of digging machine operation. Want to do good, there are a few points of master machine. Simple operation, flexible speed. There is no unnecessary waste. Take a look at the construction situation, you can quickly do a good job plan, faster completion of the work done. Take good care of the machine and butter on time... Wait! In fact, learning machine is not difficult, if you want to learn. It is so simple, you make up your mind, you can find a good master, to learn carefully, 1 months or so, you can go it alone. When learning to always touch the machine, the light does not work, it is practical... That's probably it.. Finally, tell you one of the most important aspects! Do not go to school to learn, spent money do not say, out of no use, but also from the new learning!! You can't believe it, you go to school and you cry.. That's probably the point.. Ha ha, try hard!
Q:Excavator theory
The excavator is driven by the engine work in pump operation, the pump is divided into pump and pump, and then by the operation of the hydraulic excavator driver rod of the hydraulic oil distribution to the pilot valve and main control valve, such as the hydraulic oil distribution to the main control valve, hydraulic oil delivered by the main control valve to the arm; small arms; dig bucket cylinder, and then drive the arm; small arms; digging bucket. If the hydraulic oil is allocated to the pilot valve, the hydraulic oil drives the motor through the pilot valve to make the excavator rotate and drive.
Q:What documents do I need to open the excavator for insurance?
As long as the driver's license is complete, you can do it
Q:Modern 335-7 excavator hydraulic oil temperature at how many degrees normal?
6 、 adjust the system pressure according to the requirements, avoid the pressure is too high, make sure the safety valve, overload valve and so on in normal condition work7, regular maintenance, avoid other parts wear too much to cause leakage. Timely replacement of volumetric efficiency of the hydraulic pump, because of its internal leakage will make the pump shell temperature rise, accelerate the system heating up8, regular inspection of engine speed and fan belt tension degree, so that fans keep enough speed, adequate heat dissipation, so that the equipment in good running condition
Q:What are the main parts of the excavator structure?
The common excavator structure includes power device, working device, slewing mechanism, control mechanism, transmission mechanism, walking mechanism and auxiliary facilities, etc.. These are the theoretical basis, I have learned in Henan, Zhumadian, mountains and rivers engineering machinery school! This school pays more attention to theoretical study! Lay a solid foundation for upgrading the technology!
Q:What brand is excavator WORLD?
Jiangsu city in Zhenjiang Province, the heavy industry (China) Co. Ltd. was founded in 2007, is China's key investment group strategic industry in recent years. The project total investment 10 billion yuan, covers an area of 1500 acres, the company has a large CNC boring and milling machining center, CNC horizontal boring and milling machine, Longmen double IGM welding robot, CNC vertical machining centers and CNC flame cutting machine and other advanced imported equipment, the ability of manufacturing industry occupies the leading position.
Q:How about automatic flameout of excavator?
First, the old equipment is the engine power decline, with the main pump, a little hard to suppress the car flameout.The solution is..:1. school oil pump, engine overhaul. The advantage is a temporary cure, but the drawback is that it costs a lot2. reduce the main pump flow to reduce the power of the main pump to adapt to the power of the engine. The utility model has the advantages of simple processing, time saving and money saving, and the disadvantage is that the whole vehicle will slow down.
Q:What about sunward excavator?
Sunward lost on domestic machines, small digging is fairly good in domestic sales, in the big dig on how.Cheapness。 Look, what price do you belong to?.At the end of the price to buy the country, yuchai. (cheap, no good)High price to buy 31 machines. (domestic sales first. Mainly after-sales service is good. The digging machine in the same tonnage configuration with Komatsu. Just like Hitachi. But the price is much lower than the bottom. Is the highest price of the machine) suggest to buy (a small earthquake in Japan nuclear leak is to buy 31 pump. The highest pump in 31 Chinese group)If you have money, you'll buy komatsu. Carter. No, I said. Is more than 90 years of digging machine brand)What stage do you think you belong to?. This place a lot of 31 excavator. Small to 55. to 460. after-sales really nothing to say.
Q:LOL excavator correctly installed
Say only the mainstream of playing wild routines, on a single excavator, or used to play other locations, not mainstream, do not say.The first is the playing field knife enchants, excavator not letter every day and so on by Zhao Kensai werewolf Gongsu eat hero, is not the master, so two kinds of choices, and the giant warrior enchant enchant slag. Enchant warrior is feasible, because with attack fighters possessed high damage early for wind or have the confidence to oneself, can open the situation in the early stage, reducing the CD property is also very suitable for excavator. But it is not the most recommended, because in the current version on the single is half meat output CARRY, then the tank task is mainly composed of a single and a wild bear, compared to the previous version on the single is meat, now the single version on the T1 are Nobel Jian Ji the meat output. The playing field in the middle and late stage of damage as the front bear more responsibility, so it is recommended to enchant enchant slag giant, more stable than warriors, after all the skills base damage excavator is good, is not very dependent on soldiers enchant the damage.
