Report of senior engineer hydrogen: Situation add appear rich to held water 2011, have experience of product research and development and dark market acknowledge, is excuse me performance of technology of center of machine of pneumatics of cell of company hydrogen fuel in what respect? This product whether practice uses case to you can offer reference?

Zhang Xuefeng: Situation add show gain the development work for of machinery of impeller of high end of ceaseless take root, through practice of 8 single-page calendar, once made a trade first brand. Since 2016, the company passes abundant survey, project approving throws fuel cell not to have the development of machine of oily centrifugal pneumatics, this is the item of industrialization of own research and development that the company threw a few spirit.

In time of nearly 3 years, the company broke compressor of efficient low specific speed, dynamic pressure to enrage the center such as electric machinery of float bearing, high speed and high frequency control crucial technology camp, successful research and development machine of pneumatics of in suspension of XT-FCC series energy of life (range of products but satisfactory the clean air feed that covers 30-150kW report lot is fragmentary demand) .

First our prototype “XT-FCC300 pioneer a ” once consign client stops fragmentary marry to evaluate a test with the function, obtain high opinion. Having as the company to development ability, we are OK the oldest standard satisfies client synchronism to develop demand and fragmentary and best function to marry.

Report of senior engineer hydrogen: Regard hydrogenous fuel cell as one of fragmentary center parts, is pneumatics machine indispensible and contented ability of what technology demand is truly applicable between fuel cell?

Zhang Xuefeng: To finish as far as possible high energy changes efficiency, fuel cell is external electrochemistry echo is mixed to airy temperature, humidity, pressure the demand that the parameter such as discharge is having severity. But constrictive machine cannot satisfy the industry that uses generally at present the requirement with fuel characteristic to air feed cell. Consequently the design develops one character can advantageous and can well as fragmentary as fuel cell the constrictive machine that stops to marry, about the function of fuel cell promotion and industry are begun crucial.

If say electric caboodle is the heart with fuel cell fragmentary power, that does not have oily pneumatics machine is faint lung, it is fuel cell fragmentary very important composition is local. “ heart - ultimate resolution of lobar function ” the technical degree of fuel cell and functional target.

We think machine of fuel cell pneumatics is different from traditional pneumatics machine all the time, also have do not initiate the electronic supercharger of machine at the tradition, it should be a new species, demand satisfies the empty press that applies to fuel cell not to have limits of sex of oily, low noise, high firm, efficient, miniaturization, task relatively a lot of Yan Ke such as wide, nice static echo gift, good heat management, low capital asks.

Report of senior engineer hydrogen: In what does design of machine of pneumatics of fragmentary center part live hydrogenous fuel cell difficulty?

  Zhang Xuefeng: Machine of centrifugal type pneumatics is the central component of hydrogenous fuel cell, its represented the top rate of pneumatics machine industry, touch aerodynamics, pass the numerous course such as oscillatory and heat, mechanical, mechanical, electric machinery, electronic-controlled, data and expensive precision work.

Pneumatics machine research and development not merely demand captures many individual technologies, and demand is compositive these individual technologies, the movement that makes aircrew restful and efficient. Do these individual technologies include: ? Whistle Э Gan paragraph cleanse of sip of  of ⒊ of shank of garden of Tuo of level ground of bail of  of black of vulgar of Dong of  of ⒊ of shank of garden of Tuo of level ground of bail of orangutan of Ke of ≈ of  of a legendary venomous insect of  of broadleaf plant of  of round  of  of ⒌ of ぁ of Piao Yuan commonplace of bail of  of  of enough  of clear of charming of neon of У harmonious helmet comes.

It is many 100 enterprise as (include aerospace power) the company of development work for that has provided the impeller machine that designs consult work for, the design that at present we once mastered compressor completely and make, the design of gas surplus bearing and the design that make and exceed high speed electric machinery and make.

And we and supply business together the electric machinery of permanent magnetism synchronism of custom-built development is high frequency controller, can marry well all sorts of type. In addition, every component design is put in corresponding technical accept a challenge, we go to demand consideration how balance is terrible, disable these central parts ground conformity is in together, the project technology accumulation with very rich and generous category of this demand much discipline and balance, if why the example goes up in the bedrock of the miniaturization that finish, do not sacrifice again too much function and operating mode limits. These research and development are broken and optimizing iteration is to be in situation add show gain on the bedrock with accumulative experience of research and development of old high end, it is difficult that the group is overcome through assault fortified positions of husband of long-term hired hand finish.

Come 3 years, situation add machine of the pneumatics that show gain to hold to high speed straight drive all the time centrifugal technology road. Nowadays look back on, our technical road choice is very correct. It is OK that component of overall situation ministry includes bearing, electric machinery and controller to wait be made in international and consume, we reduce the dominant position on capital in industrialization is to be likened to trenchant.

The fragmentary design as a result of every client each are not contrary, only pneumatics machine and fragmentary optimal marry custom-built design has been done, fragmentary function arrives at cell of the ability fuel that finish optimal. For this, we planned when seriation is designed collective XT-FCC technology framework, on consistent and rock-bottom technology and design framework, have very acute expansibility and custom-built sex. This design tentative idea resembles GELeapX aviation is initiated machine, framework of peculiar product technology, differ to marry plane client is fragmentary functional requirement, derive LeapA (empty guest) , LeapB (Boeing) , LeapC (Chinese Shang Fei) model of a few important clients.

Situation add appear rich to regard as have extremely strong the group to development ability, but abundant the dominant position of technical research and development that develops us, cooperate with with our client rigor research and development, joint on XT-FCC technology framework meteoric research and development takes out key client's exclusive and custom-built product version, in order to reach different clientele the acme demand to fragmentary function, at the same time this also conduces to fuel cell fragmentary client erects their respective competition advantage and technical barrier.

  Report of senior engineer hydrogen: Is product research and development right raw material whether pay attention to somewhat?

  Zhang Xuefeng: Using appropriate raw material is the bedrock of intent of the products plan that finish. In respect of mechanical and tectonic component, regard the product that faces a car to use a trade as fixed position, we are preferential chain of the raw material that chooses a car to use a system, supply and quality management system. Be aimed at certain and crucial component, we also can choose the data of aviation class, alloy of example low temperature.

At the same time we also use a few new-style data in the attempt, with promoting a product the function further, at present different program road is being optimized in collateral test in. Situation add the group that show gain to have very dark aviation power research and development and background of production work for, the project technology that develops work for project in high end experiences accumulation to be able to cross a bound to use a car use a category.

  Report of senior engineer hydrogen: Up to now, situation add market of machine of the pneumatics that show gain to extend a state how?

Zhang Xuefeng: Our market fixed position is very clear: 1, hold to a technology to lead all the time, with solid and ability of continual research and development, accomplish No.1 of functional target industry; 2, the capital control that industry of prep close behind develops demand to had done us, let an industry be blocked by foreign brand no longer neck; 3, make the most professional work for group, begin through doing poineering work a few years, we are in at present the group that Beijing, Shanghai, Chengdu, Xi'an, Jiangsu established us like Gaodou and base, achievable meteoric consign, instant work for.

2019 should be our market a year of germinant to the limit of one's capacity, demand of client of industry of our meeting follow closely, the yield that will configure us can plan. On some kind of level, the market demand secondary of our product still depends on the promotion static state of country policy, and industry client is right in the stand that fragmentary research and development and product change high-pressured fuel cell.

Report of senior engineer hydrogen: What does the pneumatics aircraft type of the mainstream on the market have at present? Will estimation come which breed can you hold larger market share?

Zhang Xuefeng: Pneumatics machine is fuel cell the important part with fragmentary air fragmentary supply, be aimed at the functional requirement with different fuel fragmentary cell, often the air with diverse demand constrictive machine marries with its, commonly used pneumatics aircraft type has machine of pneumatics of screw type, centrifugal type, vortex type and collect Ci type to wait.

Constrictive machine is in centrifugal type the respect such as power density, efficiency, noise has best integrated effect, be thought to be one of kind of air pressure boost that have an outlet most. From at present the delibrate outside international begins square all along to look, centrifugal type air is constrictive machine general will be henceforth of the mainstream develop way. In the meantime, as fuel cell fragmentary the progress that fragmentary to air supply function asks, machine of centrifugal type pneumatics and turbine marry the less important incline to that task force is sure to become fuel cell to use pneumatics machine to be begun in the future.

But machine of centrifugal type pneumatics can break out when low flow asthma brace up picture, of the function with this will serious fragmentary effect and empty press use life. Situation the machines and tools of centrifugal type pneumatics that adds the development that show gain has wider fluctuant movement range, below little flow operating mode, can achieve older pressure reduced rate, be helpful for pneumatics machine in low flow operating mode of high pressure ratio plays normal movement and breaking out asthma brace up.

Report of senior engineer hydrogen: relatively the pneumatics machine product at abroad, what are international product and its difference expression in the center of? Discern demand from what does the respect stop to break?

  Zhang Xuefeng: Inside limits of eye preexistence bound, still have no complete maturity, the product that completely contented user asks. Certain manufacturer of abroad starts earlier, degree of technology of machine of the pneumatics outside international has certain interval, but we can overtake this interval hard.

The sequential data that client of a ” evaluates our “XT-FCC300 pioneer once indicated, product function once surmounted foreign contest to taste in a lot of respects. Foreign product also is not satisfactory, in central technology break on, unusual accept a challenge and result are faced in international actually. Begin as the your kind effort of Chinese market, brand of our believe China has an advantage more instead in a lot of respects, we are very determined ground believe can have Chinese brand to win out in this category horse race certainly.

Below such setting, we should seize rare opportunity, abundant carry on oneself collective technology advantage, solid had done jobs of following a few respects: Rigor and motivation are fragmentary cooperate with research and development, demand drawing, technology is advanced; Much discipline crosses a bound to use, produce learn to grind close cooperation; Cautious and conscientious rushs forth, often build up data of product research and development.

Report of senior engineer hydrogen: According to understanding, the market that showing level is pneumatics machine guides period, also be the opportunity that pneumatics aircraft manufacturer enters market of hydrogenous fuel cell, what kind of view do you have to this?

Zhang Xuefeng: We await more international to actual strength and high grade enterprise enter this market. What benign competition just has an industry can continue to begin promote with the technology, what promote fuel cell industry jointly is in good health and meteoric begin.
