Facing Jiang Lin's replies, Bai Zheng murmured: "This...I, this...I...we really...I don't know..."

He looked at the double-acting pump in front of him, feeling confused, and asked again: "This can't be done! I... I saw the water pump on the edge of Badong City a few days ago... The pumps were all straight pipes, but there were water inlet pipes and outlet pipes on the other end..."

"Of course, the pump pump now has a shell on the outside, so that it will avoid bumps and bumps, and the other hand, it will be beautiful. The pump you see now is for teaching purposes, so take off the shell to make it easier for students to see the detailed direction of the pipeline..."

"You know that steam pumps are now used in large quantities, mostly high temperatures, rotating components, and many pipelines. Based on safety considerations, the storage of these pipelines must be done well, otherwise the operators will bump into each other and it will easily lead to accidents."

"Human life is at stake, so it's worth it to increase some costs."

Listening to Jiang Lin’s explanation, Bai Zheng was a little dazed and remembered every bit of the years.

The steamship was replaced with a new boiler, and the steam volume increased significantly. However, after nearly two years of commissioning, the speed of the steamship was still limited. Because there were still many technical difficulties that had not been solved, everyone kept holding meetings to discuss and summarized the difficulties one by one.

One of the difficulties is that the utilization rate of steam is not high, so even if the amount of steam is increased, the appropriate improvement effect is not achieved.

Just like a strong man, he was paddling in a small cabin. Because he was restricted, his arms could not be spread, so he had enough strength but could not row the paddle faster.

For this reason, Bai Zheng and his companions thought about it for a long time and thought that the cylinder size should be inappropriate, too short or too small in diameter, so the steam entering the cylinder had not yet been used up and wasted.

However, the depth of the cylinder is too large and the diameter is too wide, so they repeatedly calculated and adjusted to try to find a suitable size so that the stroke of the cylinder piston can be optimal.

The production of the cylinder is very troublesome and requires the use of the latest boring machine. However, the cutting head of this thing is very expensive and easy to break, so it is not useful if you want to use it.

The materials used in the cylinder block are also very particular, and they are special iron materials. This kind of iron material is also troublesome to smel and is not available at any time.

The piston is relatively better, but the piston sealing gasket is also not simple and time-consuming.

Due to the production process, they have to spend a lot of time every time they improve the cylinder and piston. Before they knew it, nearly two years have passed, and the optimal cylinder size has not been explored.

Now, looking at this two-way pump, Bai Zheng thought of a way to improve the efficiency of the cylinder's use of steam.

The cylinder of the steam engine is the same as the pump, with a straight cylinder, and a piston inside. There is a long rod on the piston. When the piston moves, the long rod will move back and forth. The other end of the long rod is connected to the flywheel, and the flywheel will rotate.

The principle of the action of the cylinder is exactly the opposite of the action of the pumping pump: the cylinder is steam to push the piston movement and then pushes the long rod to reciprocate, while the pumping pump is a long rod to reciprocate the piston, which then pushes the water at the other end of the piston (sucking water, spraying water).

The same thing as the cylinder and the pump is one-way action.

Now, Bai Zheng realized that there was a two-way cylinder, so he learned from it and thought of a question: Why can't there be a two-way cylinder?

There are air inlets and exhaust ports at both ends of the cylinder, which open and close in turn. When steam is placed in the left end of the cylinder, the air inlet at the right end is closed and the exhaust port is opened. At this time, the steam pushes the piston to move to the right;

When the steam weakens and the piston moves slowly, the left air intake is closed and the exhaust port is opened. At the same time, the right air intake port is opened, and fresh steam is discharged into the cylinder, pushing the piston to the left.

In this way, a sufficient amount of steam can act on the piston from left to right, and the force of the piston reciprocating will naturally rise.

With such a change, the piston in the cylinder still only performs reciprocating movements and will not have any unnecessary movements. To achieve the cross-in and exhaust of a cylinder with left and right, only a less complex linkage device is needed.

Bai Zheng looked at the two-way pump in front of him again, feeling a little lost: "This... this thing was found two years ago?"

Jiang Lin nodded: "Yes, otherwise why do you think Jiahesheng has expanded its recruitment? He just changed a pump and the steam pumping machine burned the same amount of coal, and the water pumping efficiency increased by 60%. How much coal does this save?"

Bai Zheng was speechless. Their technical research team will not announce their development situation to the public because of confidentiality, but in order to prevent behind closed doors, they have actually been paying close attention to the latest progress of steam boilers and steam pumps.

So he would write letters to Jiang Lin from time to time, asking about the progress of steam boilers and pumps, but he would not say how far they have studied steamships and what problems they have encountered. All of this is for the purpose of keeping them confidential.

This one-way technical exchange makes the outside world unaware of their specific needs, just like Jiang Lin, who is troubled by how to improve the efficiency of steam utilization in the cylinder.

Because he didn't mention the pump, Jiang Lin didn't say that the pump had been improved.

The research team is paying attention to steam boilers and transmission devices (cylinders, etc.) all day long, and spending time in the workshop, where will you think about anything or ask others questions such as "what has the improvements in the pump"?

result...

Bai was thinking about it, his eyes heated up and he suddenly wanted to cry. He felt that he had no idea what he was busy with in the past two years...

If he and his companions paid more attention to the steam pump and the supporting equipment at that time, then they might have thought of this solution at that time, instead of working hard and struggling for two years but finding nothing.

Jiang Lin saw Bai Zheng's appearance. Although he could not know what Bai Zheng was thinking, the other party's expression after seeing the two-way pump made Jiang Lin guess a little.

After patting Bai Zheng's shoulder, Jiang Lin smiled and said, "Why, you thought of a two-way cylinder?"

"Ah? You...you thought of it too?" Bai Zheng asked in surprise.

"Of course, not only me, but some people thought of this and made real things... Guess, how effective?"

Bai Zheng wanted to say "the effect must be good", but seeing Jiang Lin's expression, he knew that things were not that simple. After thinking about it, he thought about it and thought of a possibility.

Indeed, the principle of a two-way cylinder is good, but the reality is that it may not last long when it actually runs.
