The equipment inspection in the afternoon will be much faster, to half past three, ready to produce, Li Ruoyu and Anna also personally came to the central control room of the mixing building, this is a trial production, so no one wants to fail, the afternoon production task is 50 cubic meters of concrete, at this time the use of 6 square concrete trucks, so a total of eight to щwwlā

Li Ruoyu saw that all preparations were in place, so he issued an order to start trial production!

I saw that the engineer of Shi Weiying Company personally grabbed the knife, cooperated with the operator, entered the concrete production task list and mix ratio into the computer, and then started the air compressor, flat belt and inclined belt, and finally started the concrete mixing host, and observed for two minutes, and the equipment ran normally.

Operator bangs click on the operation interface, enter the amount of production and the number of each plate, and then click to start production, suddenly all kinds of raw materials began to measure, sand and gravel fell into the measurement scale, the number of weighing on the operation interface jù is also rising rapidly, after reaching the set value, the sand and gravel weighing hopper is opened one by one, the sand and gravel in the weighing hopper are put into the flat belt, and then transported to the intermediate hopper on the mixing host through the guò inclined belt.

Anna saw that Qiē was running normally, so she smiled at Li Ruoyu and said, "How is it? My big boss, are you still satisfied with this set of mixing building equipment of our Shi Weiying Company?"

Li Ruoyu said with a smile: "Anna, I have to say that your company's products are the world's top, just the computer control system, this interface is better than many companies, if you can further join the local area network, so that all the terminals of the entire mixing plant are connected, it will be more perfect." ”

Anna nodded and said: "Sure enough, it's a big brick, when it comes to the point, it's just that the LAN technology is not very mature now, and our company's technical department is also researching." ”

Li Ruoyu said with a smile: "I think you should study more about the modular design of concrete batching plant, in the future, with the development of China's concrete machinery industry, to provide users with high performance, high reliability, high mobility, good maintenance and economic equipment has gradually become the goal of manufacturers." Therefore, in order to meet the individual needs of users, concrete machinery manufacturers should adopt a multi-variety, small-batch production method, and develop new products with high quality and low price at the fastest speed. The most effective way to achieve these requirements in a comprehensive manner is to adopt modular design principles, methods, and technologies. ”

Anna said in surprise: "Oh, I didn't expect such a cutting-edge concept, you know it!"

Li Ruoyu said with a smile: "Don't underestimate me, modular design technology is based on the functional analysis of different functions within a certain range or the same function with different performance and different specifications, and divide and design a series of functional modules. The structure is simple and low-cost, and the module structure should be as simple and standardized as possible, and the connection between the modules should be as simple as possible. The modular mechanical design concept is in line with the concept of rapid design of mechanical products and the development needs of the equipment manufacturing industry, which is one of the development directions of mechanical design, and has high practical value and economic value. ”

Anna nodded: "I know, this is indeed the direction of development, I will propose it to the company when I go back." Ah, look, the first tray of concrete is starting to mix!"

Li Ruoyu also turned his head, only to see that on the display of the industrial control computer, the raw materials of the first tray of concrete have entered the mixer and are stirring, of course, the situation in the mixer cannot be seen in the central control room, but the experienced operators will judge the slump of the concrete according to the current of the mixing host.

After about a minute of mixing, under the guidance of German engineers, the first tray of concrete finally began to be discharged, Xie Zili and Qin Haijuan both ran to the mixer discharge port to see the working performance of the concrete, Li Ruoyu was actually very relieved, because the mix ratio was verified by repeated trial matching, and the moisture content of the sand and gravel was also accurately measured, plus he looked at the main current of the mixer, there should be no big problem.

Anna smiled: "Big brick family, don't you need to look at it to know the working performance of concrete?"

Li Ruoyu said with a smile: "It should be not far from ten, if it is an experienced operator, you can judge what the concrete slump is through the guò ammeter and the sound of the mixer and the sound of discharging, I judge that the concrete slump should be 120 mm plus or minus 5 mm, so the next concrete does not need to adjust the water consumption, just continue to produce like this." ”

Sure enough, the operator Liu Hai echoed: "I think what Mr. Li said should be very accurate, and the next plate of concrete does not need to be adjusted." ”

As soon as the words fell, Xie Zili ran in and said loudly: "The next tray of concrete will continue to be produced according to the first plate, there is no need to adjust, and the concrete works very well." ”

Li Ruoyu smiled and said, "Okay, listen to Chief Engineer Xie!"

Operator Liu Hai nodded and said, "Yes, Mr. Li, then I will continue to produce!"

I saw that the second tray of concrete began to be metered, conveyed and mixed again, the third tray of concrete was produced, and the trial production should be said to have been successful, Li Liangfeng, who had long been ready to take samples, pushed the bucket truck to the bottom of the mixing building, and this guy pushed the handle of the concrete conveyor to the position of high-speed rotation, slammed the throttle, and turned for more than three minutes before stopping.

At this time, Li Ruoyu and they also came down, everyone was very concerned, whether the visual performance of the concrete was accurate, after all, only when it was released for testing, it was qualified to successfully complete the trial production.

I saw Li Liangfeng push the handle to the position of reversing the discharge, and then the tank of the concrete transport truck was reversed, and the concrete with a certain fluidity came out, and the güò discharge hopper was put into the trolley, which looked really good.

Li Ruoyu said with a smile: "Okay, the first car of concrete has been produced, and the working performance has met the requirements after visual inspection, and it is ready to set off firecrackers! ”

The staff of various positions hurriedly went to stick to their posts, Li Ruoyu followed Li Liangfeng and Qin Haijuan to the laboratory to test the performance of concrete work, and Xie Zili still returned to the mixing building to guide production, and Anna also followed Li Ruoyu to the laboratory.

Just walked to the door of the laboratory, firecrackers began to sound, crackling sound non-stop, indicating that Zhongsheng New Building Materials Co., Ltd. finally succeeded in trial production, and then as long as the qualification acceptance, you can start to produce and sell commercial concrete.
