Liang Haiping did a mental calculation. Because the domestic chemical industry has just been laid, Brilliance assembled four gem scroll shafts. The ex-factory price is about 270,000 US dollars, and the four are 10,000 high AC machines. The domestic stability is not good. Brilliance chose France’s Lilesen Mago AC machine. It costs 30,000 US dollars to import this thing, which just saves the domestic gemstones of Brilliance and throws them in.
The "AC-DC" flow frequency conversion rectifier system fuel pump and analog control system are either from the technical accumulation of Spey project or from the chip laboratory, which is relatively cheap. Together, it is 20,000 to 30,000 US dollars, plus miscellaneous things such as cooling fans, boxes and pipelines. The ex-factory price of a gem power package is about 1.25 million US dollars.
Although the price of gem power pack is not low, for Northeast Locomotive Works, it is necessary to match the nose drive mechanism, reasonable car body structure and locomotive man-machine control system to reduce the workload of new machines for gem power pack. This part of the budget is 600 thousand to 700 thousand dollars
It’s still a little expensive. Liang Haiping’s consciousness smashed his lips. Three years ago, the Republic imported a batch of diesel locomotives with the code nd5 from ge in the United States. The price of a single locomotive was only 90,000 US dollars, and the ex-factory price of Long March III was about 190,000 US dollars. If you choose to reconnect two machines, it will cost 30,000 US dollars. At present, the ex-factory price of Long March III is as high as 140,000 RMB.
Of course, the traction of the Long March 3 is not comparable to that of nd5. The maximum height of nd5 diesel locomotive is only 11 km/h, and the improvement potential is limited. The follow-up models are expected to break 2 km/h. The Long March 3 is not an opponent of the same level.
Liang Haiping thought about the typical high-speed railway traction head-the quotation of German Railway Type 12 high-strength locomotive. At present, the exchange rate calculation needs more than 20,000 RMB. Although the performance of Long March III is a little poor, the price has also attracted a lot. This competitiveness is really measured by the Ministry of Railways itself.
"Minister, the ex-factory price of the two-machine reconnection Long March III gas turbine locomotive is about 141,000 units," said Liang Haiping slowly.
"After power reduction, the overhaul interval of Gemstone power package can be increased from 4 hours to hours, and the reliability will definitely be better than that of Dongfeng train gas turbine. The failure rate should be lower than that of TongND5 gas turbine introduced by the Ministry three years ago," Li Yuanling added.
Even if the hourly overhaul interval is lower than 12km/h, the calculation of operation degree means that the overhaul will be carried out only after the Long March III runs 960,000km, which is slightly higher than the overhaul requirement of Dongfeng 4B diesel locomotive with 70,000km-90,000km.
When the mechanical failure rate is lower than that of TongND5 type, it is due to the working environment of gemstone turboshaft motor, and the safety of milli-motor must be higher than that of ground mixed diesel unit.
"How much can the operation of the Long March III after the technological transformation of Haiping be? What is the highest height? " Fu Hengyu then asked
Liang Haiping roughly calculated the traction power and said, "Theoretically speaking, the two-machine reconnection of the Long March III gas turbine locomotive can reach 13 kilometers in tractable standard 25s marshalling, and the maximum operating speed of the straight road can reach 17 kilometers per hour."
In the later Republic, the single machine power of Dongfeng 11g diesel locomotive is 34k, and the standard marshalling can reach the maximum height of 17km/h. Although the weight of double-deck 25s marshalling is greater than that of Dongfeng 11g towing single-deck 25, the self-mode of the 25s marshalling car is not responsible for the whole marshalling. Generally speaking, the distribution power/ton data of Long March III and Dongfeng 11g are similar.
For Liang Yuan, it is normal that a considerable part of the factors that decided to make the four gem turboshaft motors Long March III power core refer to the later generations of the Republic Dongfeng 11g gas locomotive.
Boom!
Fu Hengyu rapped on a sand handrail and asked in a hurry, "How long will it take Northeast Locomotive Works to complete the technical transformation output of the Long March III?"
As soon as Liang Haiping heard Fu Hengyu’s output, he knew that the Long March 3 was in service. He said with a smile, "If the Ministry plans to purchase many sets, the car factory will dare to let go of the investment, and the output will definitely not be a problem."
Fu Hengyu ha ha a smile and said, "The Ministry has a plan for the morning and evening express train exhibition, and the three modifications of the Long March can meet the technical standards mentioned by Haiping. The Ministry plans to connect Beiping Wusong, Nanjing, Changsha, Wuhan, Hefei, Shengjing and Changchun with express trains at one time, and the purchase volume of the first batch alone will not be less than one."
When Liang Yuan heard this, he almost rejoiced that Fu Hengyu was going to move the most famous "pigs" before the high-speed railway of the Republic of China to the stage.
After entering the new century, Dongfeng 11g will be responsible for pulling the direct express train, and the people of the Republic expect more than Rh high-speed rail, which has become the name card of the Republic railway.
Because Dongfeng 11g looks like a pig’s head and is responsible for pulling the through express train, the abbreviation Z makes the through express marshalling railway department and the people widely known as "pigs"
In the era of high-speed rail in pig farms, people have been obsessed with it, benefiting from the reasonable price and running time of the Republic benchmark line. For example, in beijing-shanghai railway, when the special train runs from Wusong Beiping, the soft berth fare in 23 yuan is only 499 yuan, and the bus arrives at the destination at 6: 7 the next day, which is equivalent to staying in a hotel for one night.
In the 27-year glorious peak period of pigs, it was a shocking scene to watch seven or seven groups of pigs ready to go at the same time in Beiping or Wusong at that time by tracking cars every seven minutes in Beijing and Shanghai at six o’clock and seven o’clock in the evening.
Of course, this high-density direct express marshalling company also led to the high dominance of the pigs at that time, just like the Liaodong Peninsula, which grew up vertically and horizontally, and there was no vehicle to live in front of the pigs for one minute.
At that time, the most tragic thing for the Republic to choose railway travel was to take the green leather car railway and wander slowly, but behind it were murderous pigs approaching.
At that time, the beijing-shanghai railway Xuzhou section of the Republic of China came to Beijing from Wusong, Nanjing, Suzhou and Hangzhou, etc. Because of the proximity of vehicles, the Xuzhou section just merged into a line and created the famous Beijing-Shanghai thirteen pigs, which made all the green skins and red skins fearful.
Generally speaking, it is lucky for a red or green leather car to be stared at by the pigs at a corner and squatted for 2 hours to "avoid" the pigs in sturm und drang.
Liang Yuan I’s pig herd communication is 24 years after the new century, and now Fu Hengyu wants to set a famous benchmark for this Republic railway in the first 15 years.
Liang Yuan thought carefully about the possibility. Fu Hengyu just said that the simple plan is very feasible. Although it is limited to the immature technology, it takes 34 minutes for Xuzhou, which is composed of 25s towed by Long March III gas turbine locomotive, to make a temporary inspection, but the good additivity of Long March III locomotive can definitely catch up with this section when it is lost.
After all, beijing-shanghai railway Root is not built according to the standard of high-speed railway. When there are many curves in the line, the grouping can be maintained for 4-kilometers. This kind of frequent reduction and increase is exactly what gas turbine locomotive is good at.
Fifteen years before the birth of a herd of pigs, the shipping power was equally tight. In the tenth century, Xuzhou section of beijing-shanghai railway did not know how many pig heads to suppress this time, which should be much larger than the thirteen pigs in Beijing and Shanghai that our generation knew.
The nocturnal green leather car in Xuzhou section of Beijing-Shanghai line is doomed to be bleak, but it is expected that it will be possible for large-scale pigs to squat for three or four hours in the future. Liang Yuan thought with a smile.
Ps Yesterday, the number of chapters was wrong. Last night, I slept for more than 2k, and during the day, I made up more than 2k to make up a big chapter. It’s a debt of diarrhea. _
Chapter 27 Who said that Wenxuan War Five Slags
"Xiaoyuan, go and beat the TV. We want to watch your news broadcast become a pig’s head." Ning Wanjia laughed and floated in the living room.
When the two maids turned Huo Liangyuan into a pig, it happened that when the Ministry media filmed the return trip, Li Yuanling took it as a joke and told the three people. As a result, the twins were so excited that they just yelled at the video camera at 6: 35.
"Be sure to accuse me of my bleak childhood in front of the Chinese people." Liang Yuan laughed and twisted his camera.
There was a knock at the door outside Liang Yuangang’s viewing room. Ning Wanfei glanced at the door mirror and said that his brother-in-law had hit the door.
"Haiping came back quite early. I have to accompany them to drink until midnight." Yuan-ling Li said with a smile.
"Minister fu and brilliance? Luo Luo, vice president George, who dares to let go of eating and drinking, dispersed early. "Hai-ping Liang conveniently put the leather shoes in the shoe rack.
"Where’s your brother?" Li Yuanling asked.
"Liu Changhe is talking to my brother? The director of the old Qin of Anton Branch is going to retire. Liu Changhe may explain something to my brother. I guess the life documents of the generation director should arrive in the past two days."
"Mom, you will soon be promoted to the director’s wife. It sounds so awesome." Liang Yuan smiled and kowtowed to his old mother.
"Brother-in-law Liang Bobo became the director. Did we see the kind of public rail car as a special car today?" Ningwanfei curious asked
"Of course," Liang Yuan replied for Hai-ping Liang.
"Wow, that’s great. We must go to sleep and cook," said the twins excitedly.
Liang Yuan listened to the two girls twittering about the plan and couldn’t help laughing in my heart.
Because the creek is the only prosperous major branch in the jurisdiction of Anton Branch, it has always been a must-see place for the director to go out to inspect the creek. The director of Anton Branch, a well-known poor bureau, has been making the first batch of public rail cars produced after the founding of the People’s Republic of China as special cars.
The most impressive thing about Liang Yuandei’s memory of visiting the sub-director’s car is that the car office seats are decorated and the bottom of the 22-type car has been eliminated in the Republic. It is very similar to the white ceiling and khaki floor. Boxwood is painted with varnish seats. The whole car is like a mobile railway museum. Two girls imagined that the bed, kitchen and all of them have no land.
"Minister Hai Pingfu said that the batch purchase of 100 Long March 3 vehicles refers to single machine or double machine reconnection?" Yuan-ling Li asked, turning down the audio.
"Minister Fu means that a single machine is equivalent to the need for four gem turboshafts. George, the vice president of the joint venture company, specially asked Minister Fu this question."
"Hey, once the Long March III gas turbine locomotive is successfully rectified, can Brilliance’s production capacity follow?" Hai-ping liang asked some worry.
"At the time when the joint venture agreement was signed, Rolls-Royce bought one gem scroll motor, except for six gems dismantled and practiced at the time of localization, and four jewels equipped with the Long March III car. There are still nine original British gem scroll motors in Brilliance Warehouse."
"In the past year or so, when we made localization, we assembled 22 Brilliance existing libraries, which was enough for the car factory to produce two Long March III gas turbine locomotive." Li Yuanling first made a bottom with Liang Haiping.
"I’m planning to adjust the technical personnel and assembly staff in the two projects of Spey and Taiyin to speed up the localization of gemstones. I estimate that the joint venture company can gradually increase the production capacity of gemstone vortex shaft motors from two units per month to two units per month after two months." Li Yuanling said with confidence.
Liang Yuan listened to Li Yuanling and roughly calculated that the Seventh Five-Year Plan will be finished in ten months. According to his own mother’s calculation, Brilliance will be reproduced in one year. However, Northeast Locomotive Works is close to three gem scroll shafts, and there is only one gem in the remaining six months. The production capacity of Brilliance has been released, and there is no pressure to speak of.
Liang Yuan looked at Hai-ping Liang’s face and suddenly knew that his brother-in-law had figured out Brilliance’s productivity and said, "Brother-in-law, my mother’s side looks like there should be no problem, even if the productivity is a little small, there is still a lot of trouble in the UK. Is there any problem with her brother-in-law? I remember that the production capacity of the car factory has always been very tight? "
"After the integration of Shengjing Branch, if the car factory works overtime and produces at full capacity, it will be able to produce five standard groups of 25s car bottoms a year. Even if Minister Fu sends the batch to the express department morning and night, it will not be a problem for the 25s car bottoms to serve as the production capacity of the car factory," said Liang Haiping.
"Five through express trains need nine carriages less. Wouldn’t it be a fortune if the Ministry made the brother-in-law of the double-decker bus?" Ning Wanfei asked in surprise.
"How is this possible? If the Ministry sends the 25s car bottom to the designated car bottom express, his brother-in-law may be killed by several factories." Liang Yuanda said with a smile.
The bogie of 25s car bottom has been shared for a long time. Both Changchun Bus Factory and Nanjing Puzhen Bus Factory have changed their own bogies into those made by double-decker 26s bogies. The 25a car bottom produced by long-distance passengers and the ordinary 25b car bottom produced by Puzhen have passed the loop inspection of the Ministry of Railways.
This also means that the structure and degree of the 25s underbody of Northeast Locomotive Works have no obvious technical advantages over those of the other two bus factories, and are limited by the mastery of gas spring technology. The problem of floor shaking of the 25s double-decker passenger car during high driving has not been completely solved by Northeast Locomotive Works, which makes the double-decker passenger car unsuitable to be set as a sleeper car.
It can be said that in Fu Hengyu’s direct express plan, the bottom of the 25s car is hard seat and soft seat, and the sleeper car base will choose long-distance customers to produce 25a-type adjustable car bottom. Of course, it does not rule out that some "black-hearted" roads have earned dorado, regardless of comfort and hard 25s sleeper car bottom.
"Xiaoyuan’s brother-in-law has roughly calculated that the gem power package is 1.25 million US dollars, which is close to the current price. Isn’t it a little big if the localization of Brilliance Gems encounters financial pressure that hinders the joint venture company?" Hai-ping liang asked some worry.
"Brother-in-law, this fact is the whitest for my mother." Liang Yuan made signal with the lips to his mother.
The trial run of the Long March 3 was originally Liang Yuan’s old promotion, and he made a performance project. In Liang Yuan’s plan, the future Qinghai-Tibet Railway was the ultimate goal of the Long March 3, so he didn’t talk to Liang Haiping about the details of repairs and maintenance. Liang Yuangen didn’t expect that Minister Fu Da planned to start the "pigs" before the Long March 3.
"Even if the gem is successfully reduced in power and extended in service life, it will be overhauled once every two years or even one year at most. When the Dongfeng 4b gas turbine is overhauled, the power system will consume 10,000 yuan. If the Brilliance power pack is overhauled, it will cost 21,000 yuan."
"Rotary working gas turbine can make the service life longer than that of reciprocating diesel engine, or there will be no accident. A long March can last for three years, and it is much more convenient for us to upgrade the power system than diesel engine. It is better to choose the blade material, and the pneumatic structure of the fan will be added with intercooling and regenerative heat in the future."
"How much does the brother-in-law sell for new equipment with turbine motive is not the most important share, but the big head. If we can purchase one power pack in the back and match it into five groups of traction heads, the annual income of Brilliance alone will be more than 10 billion yuan. The railway field wants us to maintain the comprehensive index of gem power pack, which is not in line with the technical standards of mainstream diesel engines. This is a more stable long-term meal ticket," Liang Yuan said cheerfully.
The root of modern society is to establish an energy-based power giant market, which is similar to mining. In most cases, every set of equipment sold is equivalent to establishing a gold mine that keeps producing.
Generally speaking, the most realistic way to obtain the maintenance ability of turbine motivation is to become a turbine power manufacturer. It is this extremely high maintenance and maintenance technical threshold that makes the three power giants, Rolls-Royce, ge and Pratt & Whitney, earn billions of dollars a year from after-sales, so trying their best to make their own products wider is the ultimate way for power giants to make profits.
Of course, someone is obsessed with gas turbine maintenance, which belongs to the turbine industry. Once nuclear weapons are released, they will definitely be finished together. Maybe the whole industry will be in danger of restarting.
A few people chatting news broadcast sounded on time than familiar melody. After Luo Jing introduced the national leaders step by step, the first practical news was that the Ministry of Railways broke through the 2 km/h high-speed railway.
