DZL series package boilers are horizontal three-pass water & fire tube boilers with a chain grate stoker structure. Threaded pyrotechnic tubes are arranged in the drum to form a convection heating surface, while the drum and the water walls on both sides form a radiation heating surface in the furnace. Each package system is fully installed and wired before being transported to site and is electrically controlled to provide functions such as stepless speed regulation for the stoker, threshold parameter alert and interlock protection.

A few days ago, the reporter learned from China National Heavy Duty Truck that the new suspension system, independently developed by China National Heavy Duty Truck Group, the first domestic scientific research product with independent intellectual property rights, will be supplied in batch quantities by CNHTC Jinan Commercial Vehicle Company.
It is reported that this system that has already been put into production has been included in the standard configuration of all double rear axle vehicles by China National Heavy Duty Truck, and it has realized the integration with international advanced heavy trucks in a real sense. It not only enables the vehicle to withstand extraordinary weight, but also significantly improves the lateral stability of the vehicle, while improving the impact resistance and smoothness of the vehicle, and enhancing the comfort of the occupants.
Bigger and greater driving safety, while also extending the life of the car. The timely launch of the system has been sought after by the industry and has also formed a new “selling point†for Sinotruk's 2007 products. This is another technological achievement of CNHTC's implementation of product structure improvement, promotion of differentiation strategy and improvement of quality. As for the development of this international advanced level, China National Heavy Duty Truck has only used less than one year.
The automobile suspension is the general name for the force transmission device that connects the vehicle body and the wheel. It can reduce the vibration of the vehicle frame and the body when the vehicle is driving on uneven roads. It is the main sign of the quality and grade of the vehicle. China National Heavy Duty Truck Co., Ltd. learns from international advanced technology and independently develops a new type of suspension system that is suitable for domestic transportation conditions. The new suspension system adopts the latest structure of the world's current top heavy trucks, which not only enables vehicles to withstand exceptional weight, but also balances performance, stability, safety, reliability, etc., and truly reflects the new generation of products." Mature, safe, reliable and energy-saving." According to Mr. Wang Wenyu, Senior Engineer of China National Heavy Duty Truck Group, the system uses V-shaped thrust rods to distribute the force evenly to the two side longitudinal beams. A damping module is used between the bridge and the leaf spring to effectively reduce the axle shell and chassis. The impact will greatly extend the life of the axle housing. At the same time, it also adopts a rear lateral stabilizer to significantly improve the lateral stability of the vehicle. The life of each component of the new system under the high load is much longer than the original system, and the reliability of the chassis is greatly improved. "Sturdy construction and reliable performance make China Sinotruck stand out among its peers, defying the crowd and maximizing customer satisfaction."
It is understood that, as the importance of the products and itself synchronized with the world, the high-quality requirements for the new suspension system are unprecedented. China National Heavy Duty Truck attaches great importance to it from top to bottom, and sets up a project team responsible for the classification. . In the face of severe challenges, project participants step by step to advance all tasks step by step, using advanced APQP management tools to conduct detailed product planning and strict implementation, changing the previous long development cycle and high development costs. Using F MEA's advanced technology, we insist on prior quality control, analyze and evaluate potential failures and their consequences in product manufacturing process design, and adopt appropriate avoidance or reduction measures to achieve the best benefits.
