In response to the new requirements of the new national standard on the installation of retarder products for vehicles, the Fast Group has accelerated the pace of product technology and technological innovation in a timely manner. In January 2013, the company's newly-increased annual output of 4,000 hydraulic retarders was successfully completed and put into mass production, marking that the new generation of hydraulic retarder products independently developed by Fast have not only broken foreign The company's monopoly position in the brake system market of domestic heavy-duty vehicles and its competitive advantages in scale have fully satisfied the new requirements for efficient deceleration braking of medium- and heavy-duty vehicles. The new national standard of GB7258-2012 "Technical Conditions for Operational Safety of Motor Vehicles" implemented on September 1, 2012 stipulates: "Trucks, dangerous goods transport vehicles with more than 12 tons, and road buses and tourist buses with vehicle lengths greater than 9 meters will be mandatory. Install retarder or other auxiliary brake device". This article undoubtedly brings tremendous room for development to the domestic retarder market. As a domestic early-advanced military commercial vehicle retarder market enterprise, Fast has taken advantage of market opportunities to advance. The current development and production of hydraulic retarder retarder products have been successfully completed by Suzhou Jinlong, Xiamen Jinlong, Jinhua Youth, and Anhui. Ankai, Liuzhou Yaxing, Yutong and Shaanxi Automobile, Sichuan Automobile, Foton Motor , Shanxi Dayun, JAC Heavy Truck and other nearly 20 passenger and truck manufacturers mainstream models supporting. The reason why the Fast Retarder has so quickly won the favor of the market, in addition to the new policy terms, its superior slow performance and supporting value is the main reason to attract users. According to the Fast technicians, the Fast Reactor hydraulic retarder lasted more than six years of research and development. At present, it has successfully completed the relevant experimental verification, and successfully achieved a matching test of the control program and the mechanical assembly and vehicle. And according to China's national conditions designed a new installation interface, so that the maximum retarding torque can reach 4000N · m, can be matched with Fast 6 to 16 transmission transmission, with fast and stable braking, flexible and safe operation, good operating economy and so on . At the same time, the constant speed function of the FAST hydraulic retarder realizes the automatic control of the vehicle speed and ensures the safety of driving. In response to the individual needs of different market users, Fast has continuously expanded the spectrum and supporting range of retarder products. Since last year, on the basis of the successful development of the FH400B Series Hydraulic Retarder and the realization of mass production, the company has actively used the R&D resources of the National Enterprise Technology R&D Center to accelerate the development of the FHB320A parallel hydraulic retarder. At present, a new round of comprehensive tests and road test verifications for the internal and external characteristics of the FHB320A parallel retarder are being carried out in an orderly manner. With the acceleration of various experiments and marketization in the later period, the company independently researches and develops two series of parallel and hydraulic power. The retarder will cover all passengers and trucks with a total capacity of more than 12 tons, providing good security protection and efficient deceleration braking for the upgrading of domestic passenger cars and trucks. Based on the safe and effective braking performance of the Fast Retarder and the high economy of the vehicle, users in Xi'an and Chengdu generally report that the Fast Reactor has a simple operation and a very good braking effect. Especially when setting the constant speed gear downhill, the vehicle travels more safely, but also effectively saves the cost of replacing the brake pads, reduces the tire wear, greatly reduces the vehicle's own wear and tear, and the resulting economic benefits are even more pronounced. With excellent quality and good reputation, the technical strength and competitive strength of Fast Retarder products in the passenger and truck sectors are increasingly prominent, and it also increases the confidence of the company in developing the retarder market. Recently, with the phase-one technical transformation project of the company's hydraulic retarder put into mass production, the second phase project has also entered the equipment installation and commissioning stage. The second-phase project plans to produce 12,000 hydraulic retarders annually, which will lay a more solid foundation for companies to achieve scale, all-round, and high-quality development in the retarder field. PTA Powder
Main application:Repair and
strengthen workpiece surface, significantly
Welding method:PTA welding
Main equipment:PTA welding
machine
Flame core temperature: about 10000℃
Technological characteristics:PTA has high
temperature, concentrated energy, stable combustion, small heat affected zone,
fast welding speed, high production efficiency, easy to obtain low dilution
rate of surfacing layer, surfacing layer and workpiece matrix are metallurgical
bonding,, bonding strength is high.
PTA welding technology is one of surface
strengthening methods, which has high deposition rate, low dilution rate, and
could be applied with many kinds of powder. The manufacturing craft of PTA
powder is normally gas atomization, which reduces satellite of powder. We
supply 4 main categories of PTA powder: Nickel-based alloy powder, Iron-based
alloy powder, Cobalt-based alloy powder and Mixed Powder.
Nickel Based Alloy Powder possesses high
temperature resistance and wear resistance, it is the most popular alloy powder
applied by PTA welding both domestically and internationally. Coating hardness
is within the range of HRC 30-60. It could be applied to various industries
like agriculture, plastic, paper, marine and steel making where wear and
corrosion protection needed. Some examples are plunger, moulds, pump leaf and
screw.
Iron Based Alloy Powder is more widely used
and a more economic choice. With high abrasive resistance, it is more commonly
applied to mining tools, drilling tools and mixers of iron and steel making
industry, coal industry, shaft, oil and energy industry.
Cobalt Based Alloy Powder is recommended
for corrosion and oxidation resistance, with better hot hardness values than
equivalent Nickel based alloy powder. It is widely applied to steel making
industry, coal industry and mining industry.
Mixed powder mainly refers to NiCrBSi
mixing with other hard-phase powder such as cast tungsten carbide and other cemented
alloy powder, which allows the powder better hardness around HRC60 and
excellent abrasion resistance.
Mixed powder is more often used for mining
equipment for oil sands, lignite, oil drilling tools, excavator buckets,
extrusion screws for plastic processing, grain and oil processing, etc.
