The report of the 20th National Congress of the Communist Party of China，“Insist on putting the focus of economic development on the real economy，Promote new industrialization，Speed up the construction of a strong manufacturing country、Quality power、Space Power、A transportation power、Network power、Digital China”，“Promote high-end manufacturing industry、Intelligent、Green development”。

In recent years，China's manufacturing industry continues to grow and develop，A batch of innovative achievements have led China's advanced manufacturing industry to a new height.，Our country is accelerating from a big manufacturing country to a powerful manufacturing country.。Recently，People's Daily reporter interviewed Fan Zhengrong, a young engineer of Shanhe Intelligence.，Let's take a look at his commitment to innovation in the field of advanced manufacturing，Constantly overcome technical problems，The story of contributing youth strength to the high-quality development of China's manufacturing industry。

“This large mining excavator is our star product.。The invention solves the problem that the operation capability of the excavator is easily attenuated during continuous crushing operation in high temperature weather.，This key core technology is the first in the industry.。”Shanhe Industrial City, Changsha, Hunan，Pointing to the nearly 10-meter-tall one in front of him.“Big guy”，Fan Zhengrong, Dean of Excavator Research Institute of Sunward Intelligent Equipment Co., Ltd., was very excited.。

2006，Fan Zhengrong graduated from university in his early twenties.，Join Sunward to become an engineer，He has been engaged in excavator research and development so far.，Provide scientific and technological support for product iteration and update，It also climbs the slope and crosses the barrier for enterprises.、Development and growth contribute to the strength of youth。

2019，The company began to lay out a brand newFResearch and development of series excavators。During the development and verification of a mining excavator prototype，A difficult problem is placed in front of Fan Zhengrong.：When the mining excavator works continuously in the extreme high temperature environment in summer，Abnormally high hydraulic system oil temperature，The frequency and force of the machine strike are attenuated.，Resulting in a significant reduction in operational efficiency，A sharp drop in output per unit of time。And this question.，It is a common problem in the crushing operation of mining excavators.，No efficient solution has been found in the industry。

“New products must address this pain point.，Enhance the comprehensive competitiveness of products。”For this reason，Fan Zhengrong organized a strong team to tackle key problems.，Devote oneself to tackling this technical problem。During the high temperature period in summer，They trialed the crushing operation in the proving ground.。The hottest time is two or three in the afternoon.，It is the most favorable time for the experiment.，It is also their busiest time.。

That summer，He raced against the clock with his team members.，Has been in a tense and busy state.，Or test in the field.，Or analyze and discuss countermeasures in the laboratory，Work more than 16 hours a day，Even dreaming is doing experiments.。With such a spirit of study.，The team quickly found the crux of the problem.：During operation of breaking hammer，Hydraulic fluctuation、Energy loss、The heat of the system is very large.，When the system temperature rises,，The expansion rate of the breaking hammer core is increased.，The original perfect fit of parts has become“Bumps and bruises”，It is easy to cause the breaking hammer to break down.。

Found the crux，It is necessary to prescribe the right medicine！From morning till night、From the proving ground to the computer、From plan to 3D model……R & D personnel through time and again“Brainstorm”，Find out a good way to keep the temperature of the hammer。Even in hot weather，Parts are not affected at all.，Achieve no reduction in performance。

“It lasted more than three months.，The problem was finally solved，The whole team is boiling.！”Fan Zhengrong recalled，The sense of achievement of R & D success，Let the exhaustion of the battle be swept away.。Based on this technology，2020，It can be equipped with a larger type of breaking hammerSWE600FSeries of mining excavators come out。This achievement has attracted great attention in the industry.，Some colleagues have come to study.。

It is commendable that，A total of three new technologies have been developed in this scientific and technological research.，Used for otherFR & D of series excavator products，Including some popular models that sell well at home and abroad.。

R & D is not behind closed doors.。For 16 years，Fan Zhengrong not only collects customer feedback by telephone，It will also go to the mine project site with difficult conditions.，Field investigation and research。In research and developmentSWE600FSeries mining excavator，The R & D team lasted nearly one year.，Visited more than 100 customers continuously，On-site investigation of nearly 500 excavators。

One time，Fan Zhengrong led a team to a coal mine in Inner Mongolia.，Conduct a 15-day field test。Every day from 5am to 9pm，Everyone is squatting at the excavator construction site.，Test data related to comparative test。

“There is no shelter on the site.，The cold wind is biting、The dust is flying。At the end of the day，Hair、Clothes、The shoes were covered in soot.。Although it is very hard，But in order to get the most valuable first-hand data,，It's worth it to suffer so much.。”He said。

Nowadays，With the efforts of Fan Zhengrong and his colleagues,，Sunward intelligenceFSeries full type spectrum“A big family”More than 20 products have been successfully developed.。In the meantime，The team has also overcome many technical difficulties.，Let the new generation of products in appearance、Performance indicators、Control experience、Driving comfort and comprehensive reliability.，All achieve a leap。

All these years，Fan Zhengrong has participated in many national levels.、Major projects at the provincial level，Participated in research and development of 16 models of excavator products with independent intellectual property rights，He has also won many awards and honors.。

“As an engineer.，I feel deeply responsible.，We must firmly grasp the lifeline of independent innovation.。”Fan Zhengrong said，“In the future, we should continue to face the world's scientific and technological frontiers.、Facing the major needs of the country，Focus on conquering‘Stuck in the neck’Technology，Toward high configuration、High efficiency、Constantly strive for the R & D goal of high reliability，Push the equipment manufacturing industry to a higher level。”
