While working on various buildings, Wang Qi also took time to pay attention to other projects.
After the low-tech and large-scale engineering projects were planned, he did not interfere in the daily administrative work. He only looked at the current development situation from various documents.
Over the past year or so, one of the most developed categories has been motors.
Motor production capacity was one of the key targets for early investment in polyolefin materials, and relevant departments have been following up on subsequent matters.
Before the mass production of polyethylene materials, Fenggu Motor Factory's main task was to supply generators for steam turbines, locomotive/passenger car generators, and high-power diesel engine starter motors. Aircraft could not be ranked among them, so they could only use magic power to convert DC electricity. The way electricity is used causes great losses.
The trial production of the new generation of baking enameled wire was completed not long after Wang Qi left. Later, a branch factory was built in Lukou City to produce small motors. The original Fenggu Motor Factory now only produces products above 20 kilowatts.
After several months of production and running-in, the two factories together have a monthly production capacity of more than 4,000 motors of various types. Through the processing of the cooperative machinery factory, they finally began to distribute electric fans to each factory!
It is not that there were no cooling methods before, but the water spray cooling in the workshop and the magic temperature control have shortcomings. The former has too much humidity in the factory, which is not suitable for many types of factories, and makes people very uncomfortable; the latter is a bit frustrating in terms of cost and management. It's a headache. No matter how cheap the aluminum oxide crystal is, it costs hundreds of dollars per kilogram. It's hard to tell whether it will be pried away without someone keeping an eye on it.
Motor fans are much better, they are cheap, they can effectively improve the ventilation of the factory, and when combined with water pipe cooling, the problem of high humidity is no longer a problem.
Wang Qi asked Li Xiang to go to the motor factory to give awards on his behalf and get back some first-hand information.
Now the two factories each have a cooperative research project.
Fenggu Factory is cooperating with automobile factories and Xincheng Heavy Industries to develop motor machine tools.
The earliest machine tools used by Xincheng Heavy Industry were the overall transmission mode in which the steam engine was changed from connecting rod transmission to shaft transmission, and then distributed to each machine tool in the workshop through the main traditional shaft. The vibration of this transmission method is difficult to eliminate. Only a few technical workers can process cylindrical parts with an accuracy exceeding 0.1 mm. Special-shaped parts must be repeatedly studied to achieve an accuracy of 0.2 mm. If the workpiece is slightly larger, it must be returned to the millimeter level.
The second generation is the shaft drive type brought by steam turbines. With the help of oil floating workshops and magic inspection platforms, the machining accuracy of most types of workpieces under ten kilograms can basically be stabilized at 0.08 mm. At this level of accuracy, it can be directly processed without any The mirror effect can be produced without coating, but the workshop power distribution scheme is still not perfect.
Motor machine tools represent another upper limit upgrade of machining accuracy. Equipped with power for each machine tool, the overall energy consumption can also be greatly improved.
It’s just that Xincheng Heavy Industry has been developing for a long time and there are many types of machine tools. In order to ensure that the upper limit of accuracy can continue to increase, each type of machine tool needs to appropriately adjust the power distribution plan, and the entire development cycle will be relatively long.
The automobile factory is inside and is mainly responsible for providing gearbox solutions... which is similar to a car gearbox.
Lukou Motor Factory focuses on the civilian field. The next step is to promote household electric fans and pedal/hand-operated generators. It is also cooperating with a purely private enterprise machinery factory.
There are some differences from industrial fans. The power requirements in the civilian field are much smaller. Most household fans have a power of 100 watts. In addition, coupled with electrical safety factors, the same raw materials can produce motors several times larger.
Pedal-operated and hand-operated generators are similar. Although the instantaneous output of pedaling bicycles can exceed 1 horsepower, larger ones can produce more, but they are not sustainable. The initial plan is to make 10, 50, 100, and 200 watts. Four power versions are mainly used for testing instruments, emergency lighting, circuit maintenance, etc.
The smaller the motor power, the higher the degree of automation required to produce the same amount of total motor power. Therefore, Xincheng Heavy Industry and steel plants need to provide some technical and equipment support.
Taking into account the civil and industrial needs of the entire kingdom, the entire domestic market will require approximately 4 to 5 million units.

It's very weird. Its production threshold is normal, but its maintenance threshold is extremely low. As long as enameled wires of corresponding thickness can be purchased on the market, motors as small as tens of watts and as large as hundreds of kilowatts can be repaired by hand. Only two motors cannot be repaired. For one reason, the labor-hour fee is too high compared to the purchase cost, and it is difficult for self-employed individuals to complete the transportation and hoisting maintenance of large parts.
Before the motor was replaced, every unit sold was occupying its own living space. It could not accommodate too many similar companies, and it would easily kill itself.
If you want to be a bit obscene, you can also stipulate that private enterprises are not allowed to research and produce enameled wire. However, there is no benefit in doing so, because enameled wire can be used not only in motors, but also in small-power inductance coils. The motor factory has to produce a large number of models of photoelectric machines, which is not suitable for adding other types of production tasks. It should be allowed Folks fill in the gaps.
Two motor factories are responsible for domestic demand. Calculated based on an average service life of 15 years, the annual output requires about 300,000 motors. If washing machines and other gadgets are produced in the future, the number will increase, and it will last for a long time. Don't take into account the overseas part.
Therefore, just like aircraft, private enterprises are allowed to produce motors and sell them overseas.
There is no serious power supply system overseas, so the demand for pedal/hand-operated generators will be greater, and it can also help absorb labor in areas where disaster victims gather.
In addition to motors, the chemical industry has also made progress.
The Department of Mechanical Engineering and the Department of Chemistry of Phoenix University have the largest number of students due to the large shortage of senior talents in related industries. They have living subsidies and cooperation projects provided by enterprises and have produced some results.
The most significant branch here is the systematic study of benzene and its derivative compounds.
Benzene is commonly found in the residue after gas preparation. It has been one of the products of Rainbow Chemical for a long time, but most of it is used to make nitrobenzene and is used in the production of explosives.
Under the cooperation mechanism between universities and related enterprises, new compounds have been developed, and research on the use of existing chemical products has been expanded.
The one with the greatest potential for universal recognition is the synthesis of indigo.
Indigo is a very excellent dye, and there are native indigo plants in the local area. However, the ecological environment changes after floating islandization have complicated the distribution of these plants growing in wild forms, and the yield has dropped sharply. The realization of artificial synthesis It has significance in the development of clothing.
Most of the other achievements are things that are relatively popular in public knowledge. For example, phthalic acid is a plasticizer raw material that can be used with ethylene glycol to produce polyester fiber. It is commonly known as polyester, but don’t talk about it now. In the latter step, the small-scale production of phthalic acid has just begun to be discussed, and it is still far away from the large-scale production of man-made fibers.
There are also corresponding developments in polyethylene materials, mainly in hard plastics, paints, etc.
The results can be said to be considerable, but due to market size, many things have difficulties in industrialization. For example, a certain raw material only requires a few tons per year and is not easy to store. When producing, the versatility of the device must be considered. After producing a batch of this material, you can start producing other products. Only by reducing the idleness of equipment can you effectively allocate production costs and mass produce. Demonstration adds a lot of mental cost.
At this stage, the chemical industry has actually entered a bottleneck period. The further it goes, the more severe the production breakdown will be, and the higher the cost will be.
The demand scale of polyester fiber is relatively guaranteed. In addition to being blended with plant fibers or directly made into fabrics, it is also an excellent material for safety belts and safety ropes. Although steel ropes have higher strength, precisely because of their high strength, they pose safety risks in many environments. It's also bigger, especially the diameter is so small that it doesn't take much force to cut off the head.
A subsidy can be provided here to promote the development of mass production of polyester.
