Chapter 417: Electron tube manufacturing technology!
Chapter 421 Vacuum tube manufacturing technology!
The birth of the Thomson excavator is of historic significance, creating a human engineering miracle like the Panama Canal for the United States, connecting the Pacific and Atlantic Oceans, and setting the United States on the road to becoming an industrial power. Its industrial construction and development speed ranks first in the world.
The railway network across the country during the Tsarist Russia, the railway networks of Britain, Germany and France, the factories and cement roads that flourished everywhere during the Soviet Union, any industrialized country has these large construction machinery behind it.
This is one of the greatest inventions in human history.
The genuine Thomson, the Tsarist Russian version of Putilov, and the Soviet version of Kovrovz. With this kind of mechanical monster that condenses human wisdom, the base industry will make up for its own shortcomings, thereby greatly improving mining efficiency, and thus providing heavy industry and military services.
Laying the foundation for rapid industrial development.
In the future, excavators can be used everywhere in subway networks, thermal power stations, engineering construction, road projects, and military bunkers to improve work efficiency and save labor. Its importance and significance are self-evident.
There are currently a total of 13,000 mining workers in the major mines in the base area. If excavators are used to save 10,000 mining workers, 10,000 full-time workers, or 10,000 soldiers, can be added in other fields.
"I have seen the original Thomson in the United States, and the Soviet copy of it is the Kovrovts excavator. Of course, the overall performance of this excavator can no longer keep up with the needs of the times. Once we get the complete drawings, we can start production at the same time
While improving, the direction of improvement is based on the current mainstream fields. Steam power is replaced by an internal combustion engine, with the diesel engine as the power core. The chain drive is replaced by a hydraulic drive. The current mainstream high-pressure plunger hydraulic pump is used. The traveling chassis is replaced by a train platform similar to a tank.
Crawler drive, such changes can greatly improve the usage scenarios and eliminate the defects of relying on rail maneuvers."
Zhuang Qianding continued: "The entire excavator is divided into the original version and the new version. The original version is more often used in mines, while the new version is suitable for most work scenarios. It is a contribution to road construction and industrial development in base areas, as well as the construction of fortification defense lines for the army.
The risk is that the winter in the northern region is cold and the soil will freeze. Civil work done by a single soldier and a shovel alone is inefficient. If a small excavator can assist, the efficiency of building defensive positions can be greatly improved."
A perfect plan. Who in this world can refuse an excavator? - Yu Hua was filled with emotion when he heard the detailed plan given by Zhuang Qianding. The image of a large number of excavators from later generations could not help but appear in the back of his mind.
Full of yearning.
Sany XCMG, Carter Komatsu, Hitachi Kubota, and the super industrial behemoth Liebherr R9800 are equipped with double V-type diesel engines with up to 4,000 horsepower and a bucket capacity of up to 42 cubic meters.
This is the mecha in every boy’s heart!
Improve the efficiency of defensive position construction?
The old chief and Zhao Erlu had no reaction to the previous introductions, but when they heard about military applications, their hearts beat faster and they looked at each other subconsciously, realizing the meaning in each other's eyes.
Oops, this is...a heart-pounding feeling.
Regarding the importance of excavators to industrial development and engineering construction, the old chief cannot intuitively feel it, but if it comes to application scenarios in the military field, sorry, then I will not be confused.
"Professor Zhuang, how efficient is this small excavator you mentioned in digging holes?" Out of professional sensitivity, the old leader immediately asked the key question.
"This kind of small excavator weighs about eight tons and can move about 40 cubic meters of earth per hour. Just calculate the amount of earthwork based on this efficiency data. A tunnel of one meter deep, one meter wide, and 200 meters long can be completed in about five hours.
One excavator can complete the entire tunnel operation in one hour." Zhuang Qianding gave a general introduction to the principle and content of the calculation of excavation efficiency.
"Okay, okay," the old leader said repeatedly after hearing this. He instantly understood the importance of the excavator to the army. Such a high digging efficiency can essentially improve the combat effectiveness of the army.
A brigade engineer company is equipped with four small excavators. It only takes one day to cooperate with the infantry to secure the entire brigade's field defense positions. The strength of the positions cannot be matched by manpower. As for roads, four excavators
It can drive and build roads at the same time, which can ensure the main force's high-speed march, and can also build new logistics supply lines.
There are so many application scenarios that it is simply unimaginable.
Zhao Erlu asked aloud: "By the way, can we install a shooting platform?"
"Of course, no problem. It can be equipped with two coaxial machine guns similar to tanks. A layer of folding 20mm bulletproof armor is installed on the front. It can be put down when in use and folded when not in use. It can withstand rifle and heavy machine gun fire." Zhuang Qianding.
Zhengsheng said: "In addition, it can also be equipped with thickened buckets to open up minefields for the troops, but it is vulnerable to attacks from Japanese grenades and Type 92 infantry guns."
"It's enough to be able to open up minefields, but I can't bear to use this kind of treasure for a frontal charge." The old leader nodded and said.
"Professor Zhuang, how do we transport it?" Zhao Erlu continued to ask: "Eight tons is not a small number. The Red Star tractor cannot pull such a heavy load on wild roads."
"Don't worry about transportation. We can develop a new model based on the Red Star tractor platform and upgrade it. In terms of power, it is equipped with a 100-horsepower diesel engine. The chassis expansion remains unchanged, the towing container is lengthened and widened, and the tires are changed from a single axle and a single wheel to a double axle and two wheels.
, two in the front and eight in the back, a total of ten tires, the normal load capacity reaches 10 tons without any problem, and the overload capacity should be 30 tons." Yu Hua said with a smile, and dug a hole again without hesitation.
Anyway, he is leaving soon, and the research and development tasks cannot fall on him. He has to leave some pitfalls for the senior brothers who are nuclear-powered donkeys. They can't just sit idle and do nothing.
Zhao Erlu asked with concern: "Are there any difficulties in research and development?"
"No problem."
Yu Hua shook his head, changed the subject, and put forward his own suggestions: "As for industrial equipment, I think that in addition to excavators, we should also pay attention to the field of electronic technology. We should try our best to obtain electronic tube manufacturing technology and independently produce various types of radio equipment.
To make up for the shortcomings of the base area in the field of communications, whether it is information exchange between factories or military operations, radio stations are urgently needed."
"I'm afraid it's not easy to obtain a complete set of electronic tube manufacturing technology. The Soviet Union attaches great importance to the field of communications and will never allow any technology in the electronic field to be leaked. Before I return to China, the Soviet Academy of Communications Sciences is developing a new generation of tank-mounted shortwave radio systems.
." Hearing Yu Hua's idea, Li Qiang shook his head slightly and gave an answer based on his experience of studying in the Soviet Academy of Communications Sciences.
When it comes to radio and communications, this is Li Qiang's home field. During his further studies at the Academy of Communications Sciences of the Soviet Union, he understood very well how much the Soviet Union attached great importance to the field of communications, especially the field of communications applications.
Even the oldest and lousy tube manufacturing technology cannot be leaked to the outside world.
"It's okay. It's good to be able to give it. We can't do it ourselves. Anyway, we should solve the problems we don't have first." Yu Hua smiled: "What if Comrade Stalin is in a good mood tomorrow and approves it for us?"
Comrade Stalin is in a good mood?
Everyone couldn't help but laugh when they heard this. Even so, it did make sense.
What if it is really approved?
"Then I support it." Li Qiang immediately gave his attitude.
"Okay, let's use the excavator and a complete set of electronic tube manufacturing technology as the core project. In addition, we will match it with several equally heavyweight projects, such as the Gies 5V car, a complete set of drawings of the T-series tank engine, etc., and cooperate with a 10,000-ton hydraulic press to build a demolition house.
Effect, and in order to avoid the Soviet Union's irritation, it is necessary to add various old machine tools and forging equipment from the First World War to satisfy them." Zhuang Qianding said seriously and made a decision: "After all, these old machine tools and equipment need to be transformed
After upgrading, it can be turned into a professional machine tool for ammunition assembly line production. The quantity should be large, and the base number is initially set at 100 units."
"I have no objection." Yu Hua responded.
Li Qiang nodded: "I support it."
Although the performance of old machine tools lags behind, the actual results are not bad. Transforming and upgrading them into professional machine tools can save a lot of time.
Don’t give away the things that belong to Big Brother the Soviet Union.
The old chief and minister Zhao Erlu had no objections to this decision. They respected and trusted every choice made by the three-person expert group. The emergency meeting ended here, and the project on industrial equipment was decided. The Secretary-General carefully recorded every project.
and equipment, carefully inspected to confirm that nothing was missing, and then sealed it.
Immediately afterwards, a highly encrypted long text telegram flew northwest at the speed of light.
