SAIC and Nuggi start new energy vehicles

SAIC and Nuggi start new energy vehicles

In early July, CITIC Guoan League Gugli Power Technology Co., Ltd. (hereinafter referred to as “Gongli”) signed a strategic cooperation agreement with SAIC Motor. Both parties will fully expand and deepen cooperation in the field of new energy vehicles on the basis of existing cooperation. . This is also a bright spot in the strategic cooperation agreement signed between the two major groups of CITIC and SAIC on July 4.

The agreement shows that both Ngali and SAIC will jointly explore new energy automotive product markets, and work closely together to participate in new energy vehicle demonstration projects across the country. In the entire vehicle and power battery system technology research and development, process improvement, manufacturing, talent exchange and market In the areas of promotion and application, we will work together to establish a closer and more stable cooperative relationship; in addition, we will strengthen cooperation in vehicle announcements, standards development, and database construction to achieve complementary advantages and information sharing. Through in-depth and comprehensive cooperation, it aims to promote a more stable and rapid development of both sides in the new energy automotive market.

A person in charge of the Mongolian Gugli told reporters that the company had previously established a good relationship of cooperation with SAIC-Shenwo. At the same time, it also carried out scientific research on some new energy vehicles projects with the new energy division of SAIC. Cooperation has laid a good foundation for the follow-up cooperation between the two parties.

According to the reporter’s understanding, as early as in 2009, the Nugget Power Company began to cooperate with SAIC Motor’s Shenhua Bus Company in the field of new energy buses. At the Shanghai World Expo 2010, 120 vehicles were provided by SAIC Motor Co., Ltd. In the pure electric bus project using lithium-ion power battery system, Nugget Power provided 116 sets of power battery products for 60 of its pure electric buses. These vehicles were incorporated into Shanghai after the completion of the World Expo passenger loading mission. public transport system. At present, Ngali is providing battery systems for Shenwo's hybrid passenger cars and plug-in hybrid buses. The vehicles will be used for bus operations in Shanghai's Pudong and Puxi.

The formal signing of the strategic partnership between SAIC and Ngali will further broaden the scope of cooperation between the two sides in new energy vehicles. In the future, new energy vehicles such as the SAIC Roewe series will be expected to carry the Nugget power battery system. It will be of great significance to fully enter the new energy automotive field and realize the strategic transformation of the company in the future.

Among domestic power battery backbone enterprises, the application of Nugget power battery products has covered energy-saving and new energy vehicles with various technical routes such as pure electric power, hybrid power and plug-in hybrid power. In the first half of 2014, Ngali has achieved a good market performance.

According to the person in charge, "Because the hybrid bus subsidy policy has not been introduced yet, the current market is not good, but our products have been recognized by customers with their advantages of stable performance and high fuel economy. Therefore, we have always maintained a good sales volume. Since the first half of the year, Nuggi has received more than 1,000 orders for hybrid passenger car batteries. "Compared to that, the plug-in hybrid passenger car, due to the stimulation of favorable policies, the overall sales volume of the industry has soared. Nugget has sold nearly 600 sets of plug-in hybrid passenger car power battery products. After entering the second half of the year, the company will gradually shift its product promotion focus to plug-in hybrid vehicles and pure electric vehicles.

According to statistics, the company's products occupy nearly 20% of the market share of lithium-powered energy-saving and new-energy automotive power battery systems throughout the country. It is estimated that in 2014, the sales of Mugoli will reach about 400 million yuan.

In the first year of the recovery of the new energy auto industry, if this goal of the sales of the alliance is successfully achieved, it will undoubtedly be a remarkable achievement. The alliance with SAIC Motor’s strategic alliance will probably accelerate the change of its main direction in the next few years, which will also open up a new era in its development model.

Case 1


   A fertilizer company has 2 sets of steam turbine, model are: CB6-3.43/1.27/0.294 and CB6-3.43/1.17/0.294. Because end user`s power load and steam consumption are changed, the turbines must be reconstructed according to steam parameters, flow change and guarantee high efficiency.


   Remould Parameters: turbine max. inlet steam is 100t/h, when inlet steam is 97t/h and inlet pressure is 3.15MPa(g), its extraction steam is 62t/h extraction pressure is 1.51MPa(g), exhaust pressure is 0.21MPa(g), guarantee output is 5800KW (deviation±5% ).


   Main job of remould and overhaul:


   1. Casing was sent back to manufacture`s factory for rebuilding 2 valve seat hole, expand nozzle block steam passage.


   2. Change nozzle block, take out guide blade carrier.


   3. The original double row governing stage impeller and blade was changed to single row governing stage impeller and blade, add governing stage sheath, parts of rotor sleeve need to be changed and adjusted.


   4. LP stage 3rd diaphragm steam passage inspection optimization.


   5. Casing and rotor dismounting and assembling in factory with comprehensive inspection.

   After remolding is complete, the 2 turbine sets are running very well.


Case 2

There is a paper mill which has a set of steam turbine: B6-3.43/0.981. Due to processing consumption in workshop and load were changed, the end user request reset new back pressure and achieve the best efficiency within the shortest time.


   Parameters reform to: when rated inlet flow: 55t/h, inlet pressure: 3.43±0.2MPa(a), exhaust pressure: 0.59MPa(a), steam rate guarantee value must be 11.65kg/(kw·h), output power must be 4700KW under rated working condition. The reconstruction project is a turnkey project, from preparing components to dismount heat material, equipment dismounting and installation, till to equipment commissioning successfully.


   For reducing the work amount, keep casing and pipelines still, main jobs are following:


   1. Change front & rear gland seal and diaphragm seal.


   2. Change main shaft assembling (keep mail oil pump and coupling still).


   3. Change HP nozzle block, HP guide blade carrier and original 2 stage diaphragm, add 3 stage diaphragm, 5 stage diaphragm adopts special design for satisfy the requirement.
