"How long is this one?" The factory director looked at the woven steel wire mesh sleeve and asked.

"This 200-meter design is now being designed." Bangs can't help it, to get the kind of one-time molding production line, the technical difficulty is high, and this is the small workshop production mode of Pakistan Railway.

The high-pressure explosion-proof pipe covers several layers of mesh sleeves, and several sets of mesh sleeves of different specifications are installed on the equipment, such as producing 200 meters of explosion-proof pipes at a time, how many raw materials are added at one time, producing 200 meters, and then preparing for the second production.

This kind of small-scale production is suitable for the current environment, the integrated automatic production line has a high demand for electricity, raw material security, etc., and if the voltage is not stable, maybe the mold temperature can not be reached, and it will be scrapped.

This production is 200 meters at a time, even if there is a power outage or the machine is damaged, there is not much waste of material or anything.

Of course, in general. This kind of material is a relatively large waste, and the integrated production is no problem as long as the production is stable.

"Tsk, good, good." Sun Aiguo is very satisfied, and now the motorcycle factory is ready to hand over all the production of motorcycle accessories to other factories, but other factories are not ready.

"Don't be too tired, don't rush." Sun Aiguo looked at the bangs again, and the more he looked at it, the more satisfied he became.

"Factory director, let's rest together when this is done." Liu Hai was going to work overtime to finish this, so he went back to the village to tell the village about cabbage and take a look at his home by the way.

"Tell me if you need anything." Sun Aiguo patted Bang Hai's shoulder again.

The factory director left, ready to find trouble with the construction department, hurry up to build the plant, what is the matter, seeing that the technology of this high-pressure explosion-proof pipe should be fast, don't have the technology by then, there is no place.

After the research and development of the net sleeve machine, the next step is the production of high-pressure pipes, mainly the temperature of the nozzle mold, which has the test data of rubber.

This design is simple, mainly in the later debugging work, the process is probably that the feed port enters the nozzle mold at a certain temperature to form a certain thickness of pipe.

The first nozzle comes out, immediately the first layer of mesh sleeve, and then immediately cover a layer of rubber, and then cover the second layer of mesh sleeve, the gap of this mesh sleeve can not be too dense, too dense, and the rubber cannot be combined.

The key is this temperature, as well as the speed at which the nozzle mold comes out, so that several layers of film can be fused together with the rubber tube.

Several layers of mesh sleeves should be completed on the nozzle mold of the Jimmy factory, and it takes less than ten seconds from the inlet to the outlet, and the temperature of the nozzle is related to the discharging speed.

If the discharge is fast, the temperature will definitely be low, and if the discharge is slow and the temperature is high, it will be easy to deform, just like the hot melt water pipe, the outer layer should be melted, and the inner layer should not be deformed.......

The mesh sleeve production equipment can adjust the diameter of the mesh sleeve to adapt to the high-pressure explosion-proof pipes of different diameters.

Liu Hai was tired of drawing in the office, so he came out to see his sweet potatoes and potatoes, I don't know if it was the wasteland or the seeds, maybe it was the reason for the burned soil, and the soil bags began to crack, which was a sweet potato underneath.

Bangs recently turned over the sweet potato vine, nothing to do but also dry sweet potato stalks, this thing is delicious, modern export peninsula, small book.

After drying the bangs, the others didn't take it home, after all, the land was collective, put it here, and hand it over later.

"Section chief, this sweet potato grows a lot, you can see the sweet potato when you look at the cracked mud." Li Dali and the others have also learned to farm, pointing to the cracked soil and said.

"Well, maybe it's because of the wasteland?" Bangs are not sure, crops need to be stable, this thing is only the second year, who knows that it will be stable and unstable later.

Li Dali just said that, Li Dali didn't understand agriculture at all.

Liu Hai waited for the harvest to say, "Isn't the teacher doing agriculture with a classmate, let his classmates come and see, it's really not good, and he will promote it in the village next year."

In the next three years, natural causes accounted for a part of the factors, and some people .......

However, Hong Kong Island has opened up new sources of income, and it may not be so embarrassing.

Busy, Liu Hai didn't go back to the courtyard once, seeing that the equipment had been gradually completed, when Liu Hai went to Mr. Zhu's class on Sunday, he said hello to Sun Desheng, and he wanted to buy some meat or something in a few days.

Wang Hongmei is at home, and the bangs can't be given anything else, but it's okay to go back and bring some meat once, after all, the baby is her own, and she doesn't lack this thing.

The 250 motorcycle was still known to Petrov and others, and the bangs were just let them ride.

In the laboratory building, the equipment for high-pressure pipes has been manufactured and is being commissioned.

"Li Dali, slow down." Inside the factory, there is a pungent smell, and Liu Hai is wearing a dust mask, mainly because the gas mask is inconvenient to wear.

Li Dali and the others were also wearing dust masks, while Sun Aiguo and the others were all right, but they came closer to see it.

Li Dali lowered the speed of the nozzle by one gear, and Liu Hai watched the rubber particles continue to be transported in, and the rubber pipe that came out of the nozzle was the rubber pipe, and the speed of the rubber pipe at the nozzle automatically took away the first layer of the net sleeve, and a pressure facility was made on the net sleeve to prevent the net sleeve from shrinking into a ball.

Originally, 200 meters of pipes were produced at a time, and the production of debugging machines was qualified for 50 centimeters.

Sun Aiguo and others looked at the cut finished product, the steel wire mesh in the middle of the rubber pipe, and the explosion-proof high-pressure pipe, the main technical problem is in this rubber pipe, and the accessories at both ends are not very technically difficult.

"That's it."

"Well, it's just that some material is wasted every time it is produced." Bangs nodded.

Li Dali and the three of them turned off the machine, cleaned the water inlet, and then changed the net sleeve to prepare for the second production, of course, part of the waste can be recycled.

This kind of workshop-like equipment is not good, of course, with this equipment, you can hand it over to other experts to combine and optimize to form an integrated production line.

An hour later, the second 200-meter high-pressure explosion-proof hose of the factory, there are 180-meter qualified, and then how long the explosion-proof hose is needed, and the metal fittings are installed after cutting.

"With this, can our 500-ton hydraulic press be mass-produced?" Sun Aiguo looked at the pipe and asked.

"Yes, but some parts must be forged or die-cast, otherwise the service life will be reduced."

"What's the matter, even if it's only one-third of the service life of imports, how expensive is imported."

"It's definitely more than that."

"Hmm."

"You guys work hard a little harder, produce different types of high-pressure explosion-proof pipes, and then I'll go to the ministry for acceptance." Sun Aiguo can't wait to report, your big brother doesn't sell us, we have it.

"Done." Liu Hai nodded, but in the later production, Liu Hai himself moved, because the factory director transferred more than a dozen people from other workshops to learn technology.

Sun Aiguo's report this time, ready to ask the leaders for talents, a little cultural lesbian or something, preferably young, although Comrade Liu Hai is not old enough to get married, but first arrange to work together, familiar with it, isn't it good?
