Chapter 168 The Moon of Yesteryear
The military industry conference can be postponed, but the construction of the military industry cannot be postponed.
The No. 33 Arsenal was relocated here, but because there was no electricity, the three or four people in the arsenal could only make about ten shells a day. The efficiency was very low and could not meet the needs of the front line at all. Therefore, Xie Ning urged the construction of a hydroelectric power station at the beginning of the year.
The reason for building a hydroelectric power station is that in such remote mountainous areas with poor transportation, it is impossible to solve the problem of electricity by relying on thermal power. The only solution is to rely on local water resources and generate electricity by hydropower.
Upon arriving here, they directly participated in the hydropower project. Unfortunately, neither the people from the local industrial bureau nor the teachers and students from the industrial and transportation institute had experience with hydropower projects, so the progress was slow.
Now she not only assists with the construction of hydropower projects, but also teaches them classes in the evenings.
"Last time we talked about reaction turbines, now we'll talk about impulse turbines... It uses a free jet of water ejected from a nozzle to impinge on the runner. The pressure inside the runner chamber is atmospheric pressure, so there is a free water surface inside... There are three types of impulse turbines: bucket turbine, oblique-impact turbine, and double-impact turbine..."
Since there was no blackboard, Xie Ning hung his enormous water turbine design drawing on the wall to explain it to them.
The power plant needs to be built, but people also need to be trained. Once more people have learned how to use it, more power plants can be built in more places in the future, and she won't have to keep an eye on them all.
Besides these, the most difficult problem is the lack of materials. They are now like a skilled cook without rice to cook, because even if she can make it, it is difficult to make it without the materials.
“We sent more than a dozen comrades all over Hebei and Shanxi to look for generators, but they were either missing parts or the functions were not suitable.”
"Yes, it's so hard to find."
Xie Ning heard the people below discussing the materials, so he tapped the table and said, "You don't need to worry about the materials. Just focus on learning the design. We'll continue the surveying tomorrow."
The battle against Zhengtai was won. Xie Ning remembered that there were many mining areas there, and there must be a lot of materials. He needed to find someone to transport the materials back.
However, before Xie Ning could even submit a report, good news arrived. What surprised Xie Ning the most was that there was a 194-kilowatt diesel generator and some parts made by Siemens in Germany, which could be converted into a hydroelectric generator!
The data they obtained from their survey was just enough to power a generator of about 200 kilowatts. It was truly a stroke of luck that heaven was helping them!
When they returned, Xie Ning ate an extra half bowl of rice and asked about the situation in the fields.
Xiao Yang replied, "Although it's a bit late, the rice has already been planted, so the harvest will be a little later. We also planted some peanuts, and we've cleared a small plot in the backyard to grow vegetables for our daily meals..."
Speaking of peanuts, oil extraction is a must. I wonder if there are any oil presses here, or if they use the traditional pressing method. The traditional pressing method is not only inefficient, but also doesn't produce very good oil. Xie Ning silently included this type of machinery in his research.
Right now, we're mainly focused on the water and electricity projects; everything else will have to wait until later.
For the next period of time, Xie Ning stayed at the construction site to oversee the construction of the hydropower project, including civil engineering, unit installation, pipeline laying, power grid erection, and so on. Of course, it was still in the most basic stage, and Xie Ning was still worried about cement.
The stone and wood here are all sourced locally, but there is no cement for building the walls. They only have twenty tons, which is far from enough. Just as Xie Ning was talking about this, an old man who came to deliver food overheard and said, "It doesn't matter that we don't have cement. We can use lime mixed with red soil as a substitute. Look at that house, it's built very solidly."
Overjoyed, Xie Ning immediately started discussing it with others and then conducted a formulation experiment. The head of the technical department had research in this area, so he brought the technicians to join the experiment. In the end, they found that it was indeed feasible, and everyone's face lit up with smiles.
Xie Ning made the decision to build a large lime kiln on the riverbank to burn limestone and turn the stone into white lime!
Suddenly, an anxious voice came from the technician who led the survey team, "Engineer Xie, the data has changed!"
The water flow monitoring data dropped rapidly from 0.33 cubic meters per second to 0.2–0.183 cubic meters per second.
Director Luo, standing nearby, frowned. "If we construct according to this data, then our entire engineering design will have to be changed, and that would..."
Xie Ning didn't seem too worried and said directly, "Call all the technical staff together for a small meeting to discuss this."
At the meeting, Xie Ning put forward her opinion, believing that the engineering design should not be changed, otherwise the required power would be difficult to maintain.
Everyone understands this principle, but changes in water flow are a big problem. They rely on hydroelectric power generation, so they naturally have to rely on data for precise design.
Xie Ning softened her tone, took out a piece of paper and drew a diagram. She had been to the waterfall before, so she could roughly draw the terrain. "I encountered a similar problem when I was in the border region... so I suggest building a reservoir here to ensure a water flow of 0.33 cubic meters per second. However, this will require the Ministry of Civil Engineering to work hard."
Changing the water diversion channel means an increase in civil engineering work, which will require them to work harder.
The cadre who was named immediately straightened his back and said very seriously, "This is what we should do! As long as we can lay a solid foundation, we are not afraid of any hardship or fatigue!"
"Yes!" everyone responded.
Their goal is to light the first beacon in Xibaipo!
