Only when they are with Liang Yuan are the twins really innocent and romantic, listening to Fu Hengyu's bittersweet thoughts, Ning Wanfei said with an innocent face: "Let's go back and ask grandpa, do you remember Uncle Fu's request to join the army back then." ”

Listening to Ning Wanfei's incomparably cooperative answer, Liang Yuan couldn't help but smile and straightened out the cause of the matter, Fu Hengyu took the initiative to lean over, eighty percent of it was related to Ning Lei's victory in Nansha, as long as he was not a fool, he could basically see that the commander of the Republic Air Force in a few years would fall on Ning Lei's head, and at Ning Lei's age of only forty, he was definitely the most shining diamond king in the republican world.

As a person close to 286, Fu Hengyu must know that 286 has retreated, whether it is for the sake of the post-286 era or for his own next generation, the relationship with Ning Jianzhong is beneficial and harmless for Fu Hengyu.

After this passage was revealed, Minister Fu did not make any verbal communication with someone who was worth hundreds of millions, and directly pulled the topic to the Northeast Locomotive Factory and Liang Haiping, but let someone who was ignored risk the bad water to consider whether to let the twins not be the messenger for a while, and throw Minister Fu's flattery into outer space.

"Haiping, your resignation request will never be agreed to by the ministry. Fu Hengyu Zhengse and Liang Haiping said.

"Minister, I have promised the Civil Aviation Import and Export Corporation to be the person in charge of COMAC, and I really don't have the energy to take care of the car factory. Liang Haiping said with a wry smile.

Liang Haiping's idea of resigning has been communicated with Liu Changhe as early as last year, and it stands to reason that Liang Haiping's resignation railway system should be welcomed with both hands, after all, another good pit has been vacated, as long as the successor is not too low IQ. With the foundation of the Northeast Locomotive Factory, it is very easy to get political achievements.

However, after the Long March 3 broke through 2oo km/h, things changed a lot. Since Fu Hengyu saw the hope of completing the "morning and evening" direct express train during the Seventh Five-Year Plan period, how could he let Liang Haiping, who was in a key position, leave the Northeast Locomotive Factory.

Although the Ministry of Railways has absorbed the 243 electric locomotive technology, it is already a smooth road to conquer the operation of the 16o kilometer level. However, in terms of time, during the Seventh Five-Year Plan period, whether it is Zhuzhou factory, Dalian factory or Qishuyan factory, it is impossible to come up with a 2oo kilometer level traction head for the ministry to choose.

Without Liang Haiping in the middle of communication and coordination, God knows what year Brilliance, which is responsible for providing the power core, will improve the Long March 3, for Fu Hengyu's personal career, the experience of the Ministry of Railways and whether he can step into a higher leadership position in the future has an incomparably close causal relationship.

If the Republican Railway can be raised to a high railway threshold during the Seventh Five-Year Plan period, the hope of changing Fu Hengyu from a ministerial-level cadre to a vice-state-level cadre during the Eighth Five-Year Plan period will be greatly increased. Changing from an alternate member of the Political and Political Bureau to a member of the Political and Political Bureau can be said to be a leap forward in his career.

Fu Hengyu knows well the background of the civil aviation import and export company that just emerged from the republic, this is a large enterprise jointly funded by the navy, the air force, and AVIC, and Liang Haiping can come here to serve as the boss, if it has nothing to do with Lao Ning's family, a fool will not believe it.

"Reform is to emancipate the mind and break the box, since Haiping promised to fly commercially, I can't let Haiping be a trustworthy person. In this way, the Northeast Locomotive Factory can imitate the Guangzhou-Shenzhen Railway Company and transform it into a joint-stock enterprise, and Haiping will serve as the chairman of the Northeast Locomotive Factory, and the company can be at the helm, and the daily management work can be completed by the general manager. Fu Hengyu proposed a compromise solution.

At this point, it would be hypocritical for Liang Haiping to continue to shirk, and in desperation, Liang Haiping could only nod. said: "Thanks to the minister's wrong love, although my personal ability is limited, I have to try my best to continue to carry this burden. ”

"Those who can work more will get more, Haiping should not be too humble. Seeing Liang Haiping nodding in agreement, Fu Hengyu said with a laugh.

With Liu Changhe's old spiciness, he naturally understood Fu Hengyu's true intention to try his best to keep Liang Haiping in office, seeing that Liang Haiping agreed to concurrently serve as the chairman of the Northeast Locomotive Factory, Liu Changhe interjected and said: "Haiping misunderstood me and was not shallow, last month your depot said that the Long March could run 16o in three days, but today even 2oo broke through, and I was criticized by the minister." ”

Liang Haiping knew it. The Long March broke 2oo this matter, and the eldest brother who added it by himself patted his head to get famous, and he couldn't expose the truth, so he had to learn from Liu Changhe and push things to be cautious.

The people in the official rail car talked about the Long March for a long time, and Liu Changhe asked tentatively: "Gas turbine locomotives are only being studied in our country at present, and there is no reference in the international arena at present. Haiping believes that there is no possibility of the Long March 3 going online now. ”

"There are three main problems faced by gas turbine locomotives now, high temperature exhaust, fuel consumption, overhaul and maintenance. Liang Haiping said succinctly.

"High temperature exhaust gas is not a problem, the ministry has written relevant management regulations when developing the Long March 1 and 2, as long as the management is in place, this is not a big defect. Liu Changhe said.

"As for fuel consumption, if I remember correctly, the fuel consumption of the Long March 3 during the test run some time ago was basically a little more than twice that of the Dongfeng 4B nose, and if the operation of the Long March 3 traction standard group can be higher than 12o km/h, this fuel consumption rate is also acceptable for the department. ”

"The complexity of overhaul and maintenance is really impossible to solve in this department. Liu Changhe finally smiled bitterly.

The Ministry of Railways has been focusing on the research of Long March No. 1 and No. 2 gas turbine locomotives for more than 20 years, and two prototypes have been burned.

"How long does Mr. Li think it will take for the maintainability and reliability of the gem power package to reach the standard of online operation?" Liu Changhe turned to Li Yuanling and asked.

Due to Liang Yuan's special emphasis on the modularization of the power system, Brilliance simply named the power core of the whole set of turboshaft motor and motor as the power package, and provided the power package for the Northeast Locomotive Factory, which was packed in the Changbai Island factory and reserved for the finished product set of oil inlet and power output interface.

Li Yuanling lowered his head and pondered for a moment before speaking: "Bureau Liu, if the ministry wants to make the Long March Three reach a usable course in a short period of time, there is only one way to go, which is to implement the power reduction adjustment of the gem power pack and limit the load work of the power pack. In the case of the Long March III, if the power output of the gemstone power package is reduced by 1o%, the reliability and maintenance-free time will be significantly improved. ”

"The problem is that after limiting the output power and load explosion of the gem power pack, if you want to achieve a satisfactory traction degree in the department, you can only use the two-engine reconnection method of traction, so that the cost will rise a lot. Whether the Long March 3 can enter service quickly still needs to be weighed by the ministry and the pros and cons. Li Yuanling finally concluded.

Generally speaking, reducing the pre-vortex temperature of the turbine motor can significantly increase the service life and maintenance-free time of the turbine, but the side effect is the decrease in turbine output power.

After listening to Li Yuanling's explanation, Liu Changhe was silent, although the Road Bureau has the right to issue a purchase order alone, it is better to wait for Fu Hengyu to express his position at this time. It's not the right way to be an official.

At present, the nominal power of the Long March 3 is 822kx4, if according to Li Yuanling's new statement, the nominal power of the Long March 3 will drop to 2959k, and the original explosion output power of up to 43ook cannot be used.

This means that the Long March 3 is only one-third higher than the traction capacity of the Dongfeng 4B locomotive commonly used in the Republic, and it will definitely not meet the technical requirements stipulated by the Ministry of Railways in the case of single engine traction.

If the Long March 3 is used for double-machine reconnection traction, the power is sufficient. But the issue of cost is becoming more and more prominent.

Fu Hengyu thought for a while and asked Liang Haiping: "Haiping, if the ministry provides key support to the Northeast Locomotive Factory, how much is the price of the Long March 3 that leaves the factory in the form of two-engine reconnection?

In addition to four turboshaft motors, the higher cost of a standard jewel power package also includes a set of "AC-DC" flow conversion frequency rectification system, four high AC motors, a set of electronically controlled fuel pumps, and a set of power package analog control system. The rest are low-cost items such as boxes and fasteners.

Liang Haiping calculated that because the localization work has just been rolled out, the ex-factory price of the four gem vortex shaft motors assembled by Brilliance is about 270,000 US dollars, and the four are 1o80,000.

The "AC-DC" rheology frequency conversion rectifier system, electronic fuel pump, and analog control system either come from the technology accumulation of the Spey project, or from the chip room. It's relatively cheap, and when the three are added together, it looks like about 20,000 or 30,000 US dollars, plus the cooling fan, box, pipeline and other miscellaneous things, the factory price of a gem power package is about 1.25 million US dollars.

Although the price of the gem power pack is not low, for the Northeast Locomotive Factory, the workload of opening a new locomotive around the gem power pack is greatly reduced, and only the drive motor of the head needs to be equipped. The reasonable body structure of the car and the man-machine control system of the locomotive can be used, and this part of the budget has a budget of 600,000 or 700,000 US dollars

It's still a little expensive, Liang Haiping subconsciously smacked his mouth, the Republic imported a batch of diesel locomotives codenamed ND5 from GE in the United States three years ago, the price of a single unit is only 980,000 US dollars, and the ex-factory price of Changzheng III is about 190,000 US dollars, and if you choose to reconnect the two machines, it will cost 380,000 US dollars, and the ex-factory price of the Long March III is as high as 140,000 at the current exchange rate.

Of course, the traction degree of the Long March 3 is not comparable to that of the ND5, and the maximum degree of the GM ND5 diesel locomotive is only 118 km/h, and the improvement potential is limited, and the Long March III, which is expected to break 2oo km/h in the subsequent model, is not a level of opponent at all.

Liang Haiping thought about the quotation of the typical high-speed railway traction locomotive - Deutsche Bahn 12O high-electric locomotive, which requires more than 2ooo yuan at the current exchange rate.

"Minister, the ex-factory price of the Long March-3 gas turbine locomotive is about 140,000 units. Liang Haiping said word by word.

"After the power reduction, the overhaul interval of the gem power pack can be increased from 4ooo hours to 8ooo hours, and the reliability will definitely be better than that of the Dongfeng series internal combustion engine, and the machine breakage rate should be lower than the general-purpose ND5 internal combustion engine introduced by the ministry three years ago. Li Yuanling added.

8ooo hour overhaul interval, even at a lower operating rate of 12o km/h. It means that the Long March 3 will only be overhauled after 960,000 kilometers, which is slightly stronger than the overhaul requirements of 7o-9o miles for Dongfeng 4B diesel locomotives.

As for the failure rate of the ND5 type, which is lower than that of the general-purpose ND5 type, the safety factor of the engine must be higher than that of the diesel unit mixed on the ground.

"Haiping, how much can the operation of the Long March 3 after the technical transformation be, and what is the maximum height?" Fu Hengyu then asked.

Liang Haiping roughly calculated the traction power and said: "Theoretically. The Long March-3 gas turbine locomotive can tow a standard 25S train to reach an operating degree of more than 13o kilometers, and can reach a maximum of 17o kilometers per hour on straight roads. ”

The Dongfeng 11G diesel locomotive of the Republic of later generations, the power of a single engine is 3O4Ok, and the standard marshalling can reach the highest degree of 17O km / h by means of double-engine reconnection, although the weight of the double-layer 25S marshalling is greater than that of the single-layer 25T of the Dongfeng 11g traction, but the 25S marshalling adopts the carriage self-power supply mode. There is no need for the head to supply power to the entire group, and in general, the number of power/ton distributed between the Long March 3 and the Dongfeng 11g is roughly the same.

For Liang Yuan, the decision to use four jewel vortex shaft motors as the power core of the Long March 3 was largely due to the reference to the Dongfeng 11G diesel locomotive in the later generations of the Republic, and it is normal for the operation of the two to be the same.

Bang!

Fu Hengyu tapped the sand handrail and asked hurriedly: "How long will it take for the Northeast Locomotive Factory to complete the technical transformation of the Long March III." How's the yield?"

As soon as Liang Haiping heard Fu Hengyu mention the output, he knew that the Long March 3 had a door to enter service, and said with a smile: "How many units does the ministry plan to purchase, if the purchase volume is large, the car factory will dare to let go of investment, and the cost and output will definitely not be a problem at that time." ”

Fu Hengyu laughed and said: "The ministry has a direct express train exhibition plan that arrives day and night, as long as the Long March 3 modification can meet the technical standards mentioned by Haiping." The ministry plans to open direct express trains from Beiping to Wusong, Nanjing, Changsha, Wuhan, Hefei, Shengjing, Changchun and other places at one time, and the purchase volume of the first batch alone will not be less than 1oo vehicles. ”

Liang Yuan almost burst out loud when he heard this, Fu Hengyu was planning to put the Republic Railway in the future, the most famous "pig herd" before the opening of the high-speed railway, on the stage.

After entering the new century, the direct express train pulled by Dongfeng 11G is even more prestigious among the people of the Republic than that of the Republic of China, which has become the business card of the Republic of China. Because the shape of the Dongfeng 11g resembles a pig's head, and the direct express train that it is responsible for pulling is abbreviated as ZT, the direct express marshalling is widely called "pig herd" in the railway and among the people.

The reason why the pig herd is still remembered by the people in the era of high-speed rail is due to its reasonable price and running time, taking the Beijing-Shanghai Railway, the benchmark line of the Republic, as an example. The whole operating time from Wusong to Beiping Zhite is 11 hours and 58 minutes, the soft seat ticket price is 283 yuan, and the soft sleeper is only 499 yuan, and the car is between 6 and 7 o'clock in the evening, and the destination arrives between 6 and 7 o'clock the next day. It's the equivalent of staying overnight in a hotel.

In the peak era of the glory of the pig herd in 2oo7, just to meet the daily passenger flow of Beijing and Shanghai, the two stations in Beijing and Shanghai must be tracked at intervals of seven minutes from 6 o'clock in the evening to 7 o'clock in the evening, and five to eight consecutive marshalling groups can meet the strong demand.

Of course, this kind of high-density direct express marshalling company also led the pig herd to have a supreme dominance on the railway of the Republic at that time, and the Liaodong Peninsula on the long railway, the gods block and kill the gods, and the Buddha blocks and kills the Buddha, and no vehicle can survive in front of the pigs for 1o minutes.

At that time, the most tragic thing about choosing to travel by rail in the Republic was to ride an ignorant green car on the railway, but behind it was a murderous herd of pigs approaching.

In that year, in the Xuzhou section of the Beijing-Shanghai Railway of the Republic of China, the pigs from Wusong, Nanjing, Suzhou and Hangzhou and other places entered Beijing because of the similar train time and happened to converge in the Xuzhou section, creating the famous Beijing-Shanghai Thirteen Pigs, which made all the green and red skins frightened.

Generally speaking, whether the red or green car is targeted by the pigs, it is lucky to squat for 2 hours at a small station where the name cannot be called.

Liang Yuan's pig herd was opened in 2oo4 years after the new century, and now Fu Hengyu actually wants to set a well-known benchmark for the railway of this republic fifteen years in advance.

Liang Yuan thought about the possibility carefully, and felt that the simple plan that Fu Hengyu just said was very feasible, with the Dongfeng 11g traction straight special as a reference, although limited to the immature technology, the 25S marshalling pulled by the Long March 3 gas turbine locomotive had to be carried out in Xuzhou for temporary inspection, it took 3o-4o minutes, but the good additivity of the Long March 3 locomotive can definitely catch up with this lost time.

After all, the current Beijing-Shanghai railway is not built in accordance with high railway standards at all, there are many line curves, and the marshalling can only maintain 4o-8o kilometers when cornering, this frequent reduction is exactly the field that gas turbine locomotives are good at.

In the eighties, when the air capacity was also tight, the Xuzhou section of the Beijing-Shanghai Railway did not know how many pig heads to hold this time, and it should be much larger than the Beijing-Shanghai thirteen pigs that I knew in my previous life.

The green cars traveling at night on the Xuzhou section of the Beijing-Shanghai line are destined to be bleak, and in the foreseeable future, squatting for three or four hours to avoid a large pig herd is a possible thing, Liang Yuan thought with a smile.
