Chapter 63 Manufacture of Diesel Engines

Lao Yi still chose to come to No. 3 Lane 181 at ten o'clock in the evening, and Dewey agreed with Hu Wenkai's suggestion.

Lao Yi took out a piece of paper and recorded Paesa's daily itinerary and address in detail, and there was a clue that was noted, but he heard that Paesa had kept a Dutch woman on Henry Road for more than three years.

Hu Wenkai pointed to this place and said: Lao Yi arranged for the non-commissioned officers to follow Pa Aisa, and then arranged for two non-commissioned officers to squat on Henry Road to guard Pa Aisa to find out his residence on Henry Road, and arrange for someone to go to the market tomorrow to buy puffer fish.

Lao Yi nodded in agreement and asked Hu Wenkai when he would arrange for him to go to Vietnam. Hu Wenkai looked at him with disdain and said: Do you think that if Paesa is not removed, there will be results in going to Vietnam?

Lao Yi clapped his hands and said: There is really no pie in the world, it is all about exchange to have benefits.

"Hurry up and go back to writing lesson plans, you're going to give a lecture on stage these days, with snacks." He stood up and stretched.

When Lao Yi was about to leave, he said, "By the way, let's go to James first, and ask if Paesa has a lot of money in the bank and whether there is a safe deposit box." Don't ask specifically, say a few more people to find some topics to ask. No one can say that if the news goes out, the French will push us out as scapegoats. ”

Lao Yi looked nervous and said, "You don't need to say more, I know the danger." ”

The busiest time has passed, the power plant equipment has been rushed back, and the financing has been successful, and now it is a time to fight for time, methods, and IQ training talents.

This matter is urgent, and the time to boil frogs in warm water for a few months will not succeed, and it was originally planned to recruit some managers who graduated from college for training after the year, and the construction speed of Tianfen was unexpectedly fast, and the labor force was a lot in China, but there was a shortage of managers. Before the year, it was necessary to keep transporting management personnel to Tianfen, and it was impossible to wait for Hu Wenkai to prepare after the year.

He is going to organize more than 30 employees with a college degree into two groups, and all employees will be reorganized without any department. In the centralized training, one person from each group was randomly selected to come to the stage to talk about his feelings, talk about his vision for the development of the company, and analyze his shortcomings since his work.

After work on Tuesday morning, I drove directly to the factory on Yatian South Road, and the furniture produced in the furniture workshop in the factory received satisfactory feedback in the United States, and the orders for furniture and flooring were doubled by the other party.

Li Congshan accompanied Hu Wenkai to inspect the production situation in the factory, and the road leading from the band saw factory to the drying room was laid with rails, and piles of wet material were transported to the drying room through flat cars on the rails.

The drying room has been running 24 hours a day, and almost all of the furniture workshop uses mechanical operations, electric planers, electric drills, electric saws, and modified stamping equipment. Hu Wenkai said to Li Congshan that no matter how tight the construction period is, we must pay attention to production safety, must not have work-related accidents, and must comply with the requirements of the operation manual when using mechanical tools.

The main thing I did today was the development of the diesel engine, which was stumped on the fuel injection pump.

Seeing the handmade fuel injection pump in the factory, Hu Wenkai's eyes were straight, the fuel injection pump was very exquisitely manufactured, and the cam and plunger were not worse than those of later generations. Hu Wenkai stuck the four fuel injection pumps on the cylinders, replaced diesel with water, and used the hand crank to drive the fuel injection pumps to work, control the fuel injection time and fuel injection volume, and there were problems.

Hu Wenkai dismantled the fuel injection pump to explain the raw materials When the plunger rotates, the start time of oil supply remains unchanged, and the end time of oil supply is changed due to the change of the position of the plunger hypotenuse to the oil return hole of the plunger sleeve. As the piston rotates at different angles, the effective stroke of the plunger varies, and so does the oil supply.

The greater the angle of rotation of the plunger for the non-oil supply level 1, the greater the distance from the upper end face of the plunger to the hypotenuse of opening the oil return hole of the plug sleeve, and the greater the oil supply, if the angle of rotation of the plunger is smaller, the oil cut starts earlier, and the oil supply is also smaller.

When the diesel engine is stopped, the oil must be cut off, for this purpose, the longitudinal groove on the plunger can be turned to the oil return hole directly opposite the plunger sleeve. At this time, in the whole plunger stroke, the fuel in the plunger sleeve has been flowing back to the oil channel through the longitudinal groove and oil return hole, and there is no oil pressure process, so the oil supply is equal to zero.

There is no problem with the imitation of the whole fuel injection pump, the key error is in the debugging, the debugging angle is the key, Hu Wenkai explained the debugging of the oil supply time, removed all the oil outlet joints, rotated the dial to make the oil outlet of the 1 cylinder just start to bump oil, aligned the ruler with an integer scale as 0 scale, rotated the dial according to the working order, and observed whether the interval angle of the oil supply of each cylinder is 40 degrees, and its deviation is within the range of 0.5 degrees. These questions are just a kick in the door, and everyone suddenly understands when they say it.

He said to the engineers not only understand but also write how to understand, how to optimize the fuel injection pump, I put forward an idea, after our diesel engine is manufactured, our thinking should develop by leaps and bounds, this is the four-cylinder in-line fuel injection pump diesel engine after the success of the diesel engine can not be developed twelve-cylinder in-line fuel injection pump diesel engine.

The twelve-cylinder is more powerful and can be used on large ships, heavy trucks, and tanks. Therefore, we should record every problem, which can provide ideas for our future development. plum

Cong Shan believes that it is better to thoroughly understand the four-cylinder technology first, and then tackle the six-cylinder diesel engine, and the meal must be eaten one bite at a time, and the road must be taken step by step. Hu Wenkai did not take Li Congshan's words and said: "After the four-cylinder diesel engine is built first, some people will develop crawler tractors, and some people will continue to develop four-cylinder diesel engines, and the main task is to make them smaller and can be produced on a large scale." ”

The machinery and equipment that will be transported to the Tianfen construction site are being packed, screws, steel nails, bolts, alloy shovels, alloy pickaxes, steam units, modified machine tools, etc., and the second Xingye No. 01 passenger ship will set sail for Tianfen in the afternoon.

Holding a stainless steel soup pot, Hu Wenkai wanted to laugh, which was completely unintentional. After the first 100-ton hydraulic press was developed, he guided the production of the soup pot mold of later generations at will, and used it in the factory canteen after it was pressed.

People in the factory actually saw the company's Shuangxi brand soup pot imported from the United States in the department store on Nanjing Road. Yang Siliang from Yuantianfen asked for four soup pots in the required supplies, which were estimated to be used to stew seafood.

Li Congshan picked up the soup pot and knocked on it and said: "The order in Europe has been signed for France* 1,000, and the American seller has asked us to provide samples of different specifications, which have been sent. ”

Hu Wenkai asked: How about the order from Jiangnan Shipyard?

Drawings of pipes, valves, and hatch doors needed by the Jiangnan shipyard will be delivered next week, and the factory has vacated a building dedicated to the production of shipyard orders.

Hu Wenkai was puzzled and asked why he had to vacate the factory instead of building a factory on the new land if he had not purchased ten acres of land adjacent to the factory.

Li Congshan pretended to be mysterious and said that he would go to the conference room to explain, and when he arrived at the conference room, Li Congshan uncovered the cloth on the wall of the conference room, and a factory plan of Yatian South Road was revealed. The newly acquired land is divided into a corporate R&D center and a teaching area consisting of three rows of bungalows, along the fence is a two-row bungalow accommodation area.

Hu Wenkai appreciates this plan very much, the R&D center and teaching area are projects that are in short supply for the company, and Shanghai is not suitable for large enterprises to settle in, but it is very suitable for R&D and teaching and training.

"Who designed the plan?"

"Yang Siliang and a few engineers made it up and reported it to Manager Ivanov for approval." Li Congshan was also very proud, although it was not from his handwriting.

"Show me the budget report".

The budget is very good, the whole cost is 96,000 yuan, in line with the approval authority of Lao Yi, the bricks used are all waste bricks of the factory, and the doors and windows are also old doors and windows that have been demolished, and the entire budget is cut to the limit. Looking at the planning map, Li Congshan called to the front of the map and said: "This dormitory area is placed on both sides of the factory gate, and a two-story building is built, where people live on the top, and shops sell furniture and machinery produced by the factory below. ”

Li Congshan said: "The budget will be overrun. ”

Hu Wenkai wrote a few words on the budget book to return and redo, saying: "Redo the budget report and send it to the company for approval, pay attention to the order of building a training area and a accommodation area, and finally build a research and development center." ”

Carrotta called the factory and asked Hu Wenkai to bring more cooked dishes when he went home, and there were more people who came to eat today, afraid that the dishes prepared by Liu's mother would not be enough.

Hu Wenkai smiled at Li Congshan and said, "Carrotta asked me to bring vegetables home, and you just happened to go to Lane 181 with me for dinner, and several of them were there." ”

"Boss, you don't have to buy groceries, I'll go and let them pack it and bring it with you in the cafeteria. These days, a few young men from Russia are cooking, which is quite delicious. Li Congshan went directly to the cafeteria.
