The transition from B2B to B2C from "B" to "C" is the continuous exploration and improvement of Dongfeng Cummins in service. Regarding the service, Wang Chunguang said that Dongfeng Cummins is constantly improving its service, especially in the service personnel and service programs. For example, Dongfeng Cummins can provide double-election services for large customers. During the more efficient operation, the “Double Eleven Guarantee†activity was launched, and the vehicle was inspected in advance. The Cummins C-link system was used to pre-judg the vehicle, and then the service personnel and line support work could be carried out through the offline service personnel. Failure to prevent problems before they happen. This active service not only appears in the peak period of goods such as “Double Elevenâ€, but in addition to the express delivery industry, in the future, Dongfeng Cummins will cover all service systems. The "Double Eleven Guarantee" provided by Dongfeng Cummins is a typical B2C activity in the eyes of President Wang. Mr. Wang said: "With the increasing influence of the group's major customers, in the field of medium and heavy trucks, especially in the face of such big customers as "four links and one big", they gradually make their own choices in the power chain, and It can lead the industry to use the weather vane, so the previous B2B form can no longer meet the business needs, which requires Dongfeng Cummins to jump to the B2C and go to the end user to do the work, in addition to the 2018 "Double Eleven Guaranteed Live" event, we There will be other arrangements, such as establishing direct business contacts with domestic and large-sized fleets, not just selling engines , services, accessories, along the way, big data cooperation, etc., the provision of active service programs, let Best delivery companies such as Baishi and Shentong felt Dongfeng Cummins. In our internal, under the demand of pulling the terminal, we will put more resources into the front line, let the users who really use the car, feel the brand and products of Dongfeng Cummins, let them use our products, and are willing to recommend us. product". Indeed, now, the cost reduction has become a trend in the logistics industry. For the engine manufacturer, the initiative to attack is really for the sake of the user. Obviously, Dongfeng Cummins has already taken the lead. The service is upgrading Dongfeng Cummins’s National Six products, which are also “intensive and orderly†"Intensive, orderly" is the eight-character description of Dongfeng Cummins' six products. According to Mr. Wang, Dongfeng Cummins's National Six products ranged from 4 to 14 liters, covering everything from light to heavy duty. As we all know, Dongfeng Cummins has been dominated by medium horsepower for many years. After the changes in market demand in recent years, Dongfeng Cummins has gradually moved toward high horsepower. Now the ISZ engine has reached a total of about 20% in the entire 13-liter displacement segment. Guoliu Dongfeng Cummins will continue to exert its efforts on high horsepower. The Z series engine will be newly designed, the displacement will be increased to 14L, and the maximum torque will exceed 2800N·m, meeting the needs of domestic customers for greater power. In the field of light vehicles, Mr. Wang also said his opinion. He believes that Dongfeng Cummins had no light engine products, but now Dongfeng Cummins' product power is also deferred. Our newly designed Guoliu D4.0 products are mainly aimed at Light truck market. Indeed, Dongfeng Cummins, which has more and more comprehensive product coverage and continuous improvement in product performance, will become more competitive in the National Sixth Platform. And this is also supported by strength. It is known from Wang Zongkou that many of the core systems of the National Six products are designed and produced in the Cummins system, including key in-cylinder combustion optimization systems, fuel injection systems, air intake treatment systems, electronic control systems, filtration and exhaust aftertreatment systems. The system therefore has great advantages in terms of product performance consistency. In fact, Cummins has been a pioneer and leader in global emissions technology. As early as 2005, Cummins launched the research and development of Euro 6 technology, and has a wealth of successful application experience in Europe and North America. In 2015, Cummins successfully upgraded the national six power technology route of non-EGR design through the revolutionary innovation of intelligent control technology and combustion technology, and joint research and development tests with Chinese OEMs, combined with the recommendations of Chinese end users. The DPF+DOC+SCR integrated aftertreatment system meets stringent emission requirements while significantly improving engine reliability and fuel economy. Based on Cummins' technological superiority and unique innovation in the National Six solution, Dongfeng Cummins will build the core competitiveness of its products and provide users with more optimized power solutions. Products and services are the hardware and software of the enterprise, which is the embodiment of the comprehensive strength of the enterprise. For Dongfeng Cummins, which has joined the global power market competition, it is necessary not only to create products with core competitiveness, but also to continuously improve and enhance soft power in services. Now Dongfeng Cummins, using products and services to deepen the terminal, constantly open up the market, the future can be expected! Feiyiya Inclined Plate Clarifiers Use Gravity & Innovative Engineering
A gravity clarifier is the most economical method of removing solids from liquids, using natural gravity as the source of energy and it is free. A clarifier simply provides a non-turbulent zone where heavier than liquid solids, suspended by turbulence, are given sufficient time to settle to a quiescent surface. The HEI inclined plate clarifiers are compact units with multiple layers of settling area utilizing less than 25% of the floor space required by conventional clarifiers.
Principle of Clarifiers
A particle carried forward by the velocity of the liquid flow must settle at a rate that allows it to reach the bottom before passing through the clarifer. Thus, particles beginning at a point [a" must traverse some route lying between ab and ab` in order to avoid being carried over the outlet.
If V is the horizontal velocity of the liquid, S the solids particle vertical settling velocity, L the length of the settling device, and D its depth, then particles entering at point A will settle to the bottom of the device only if V does not exceed: S(L/D)Since Vmax / S = L / D then, Vmax = S (L / D)

Therefore, the velocity at which a horizontal clarifying device may be operated successfully is directly proportional to its length and inversely proportional to its depth.
This analysis applies to multiple horizontal plate units also. The spacing between plates is usually a few inches as opposed to a depth of several feet in a horizontal tank; therefore, [settling-out" times are dramatically reduced. The flow must be non-turbulent to prevent settled solids from being re-entrained within the moving liquid. Small plate spacing and a large surface area permits laminar flow at higher velocities than large horizontal tanks would allow.
Horizontal clarifying devices become self-flushing if they are inclined at an angle which exceeds the angle of repose of the settled solids. In such cases, flow enters the lower end of the device where settling particles move to the floor eventually sliding back out the entrance. Clear effluent leaves the top of the device.
However, when the device is inclined, the furthest settling particles no longer fall through distance D but some longer distance D`. This new longer settling distance D` is related to D by the relation: D = D` cos Ø.
Theta [Ø" is the angle, the device is inclined to the horizontal plane. Thus settling distance is increased by the factor: 1/cos Ø In the case where Ø = 60º, 1/cos Ø = 2.
The maximum settling distance is twice the distance between the plates. It is apparent then that the lower the angle of inclination, the smaller the settling distance. However, the angle of inclination must exceed the angle of repose of the solids to be separated. The previous equation may be modified to express the cosine of an inclined plate clarifying system as:
Vmax = L / (D / cosØ) (s) = L·cosØ / D (s)
Inclined Plate Clarifiers
A reduction of the required floor space is acquired by diminishing the separation between the horizontal plates to a few inches and stacking the settling surfaces. Inclining the plates to provide self flushing, 45º for heavy particles and 60º for light particles, reduces the available horizontal projected area (effective settling area) by a factor equivalent to the cosine of the angle. The surface area diagram (below) graphically compares the floor space requirements of an HEI inclined plate clarifier with the equivalent horizontal projected settling area.
Settling Rate
The settling rate for a specific solids should be determined by standard laboratory tests. Light particles, such as metal hydroxides, usually require a design parameter of 0.25 – 0.50 gallons per minute per square foot of horizontal projected area. These low density solids require the inclined plates to be set at a 60º angle to induce the particles to slide down the plate. Heavier particles (such as sand that easily flow) will readily slide from plates set at a 45º angle.
Maximum flow rate of an inclined plate clarifier is based on the flow rate per unit of a horizontally projected surface area. Retention time in the clarifier is not a design criteria. However, attaining optimum performance requires the prudent design to recognize several additional, very important factors.
At present, with the transformation of the transportation environment and customer needs, active service is the key to maintaining the relationship of the logistics market. The market's savvy Dongfeng Cummins realized this change very early, and exerted its strength in service, exploration and improvement. This year's "Double Eleven" took the initiative to attack the security sector, expand the service frontier, and set up the service station directly in logistics. inside company. In this service guarantee activity, China Truck Network reporter interviewed Mr. Wang Chunguang, deputy general manager of Dongfeng Cummins Engine Co., Ltd., and made a directional and detailed interpretation of Dongfeng Cummins' development strategy at the service and product level. Upgrade customer service, National Six products cover the whole line, there are both services for customers and technically savvy products, the constant efforts, the change of Dongfeng Cummins advantage will become more obvious, the competitiveness will become stronger and stronger.
