Our company is a domestic enterprise integrating boiler design, manufacture, sales and service. 600 sets of advanced manufacturing equipment, such as CNC tube bending machine, CNC drum drilling machine and automatic welding in drum, have greatly improved the production efficiency and quality. Thanks to the implementation of lean production projects, all employees of the company have established the awareness of good quality.
ZOZEN Boiler not only has advanced production technology and equipment, but also introduces many high-tech measuring and testing equipment, which provides a powerful guarantee for manufacturing high-quality products. In this video, the quality inspector of ZOZEN Boiler is re-inspecting the steel in the factory through spectral analysis instruments. Each atom has its own characteristic map. After spectral analysis, the quality inspector can ensure whether the raw materials meet the standards, and effectively control the boiler quality from the source.
ZOZEN SZS series double drum vertical gas-fired watertube boiler is a typical medium and large-sized gas-fired boiler, with a capacity of 20-110t/h and a pressure of 1.25-5.3MPa, which meets the needs of steam and heating for most enterprises. According to the different performance parameters, ZOZEN SZS series gas-fired boilers can be divided into self-contained, assembled and shipped in bulk. The SZS gas-fired boiler shipped to Hebei this time was delivered in bulk, and the video shows the drum, an important pressure-bearing component of the boiler, which plays the role of steam-water separation.
The excellent quality of ZOZEN Boiler comes from every working procedure. A convection tube bundle consisting of thousands of tubes is arranged between the upper and lower drums of SZS gas-fired boiler, and each tube should be welded with the drum with high quality to ensure tightness and no leakage. In this part of the work, it requires a large amount of welding with strict requirements, and the welding operation condition is tough. However, the employees of ZOZEN frontline cooperate with each other to ensure the efficient and orderly welding of convection bank tubes.
Convection bank tubes connect the upper drum and lower drum in bi-drum boilers. These bank tubes not only act as raisers and down comers between the drums but also carry the weight of the bottom drum in the case of top drum supported boilers.
ZOZEN Boiler is an enterprise specializing in the production of industrial boilers. Its thermal oil heater is divided into YQW series horizontal oil-fired and gas-fired boiler, YQL series vertical oil-fired and gas-fired boiler and YLW series coal-fired boilers. According to different biomass fuels, ZOZEN Boiler has designed different grate widths, lengths and air distribution systems, and the system is combined with different front and rear arch designs, to ensure that different fuels can be burned stably and fully.
In order to improve employees' awareness of safety in production, ZOZEN Boiler has adopted a safety education system, which is divided into three levels: factory level, workshop level and team level. At the daily team meeting, the team leader takes safety production as an important meeting content to publicize, further clarifies the responsibility for safety production, to improve the safety awareness and sense of responsibility of employees, and to avoid accidents in production. Welding in limited space is a common work environment for ZOZEN workers. Therefore, the frontline workers will dress well with the protection masks and long-sleeve overalls.
Boiler drum is one of the important components of boiler body, and its manufacturing requirements are strict. As a powerful boiler manufacturer, ZOZEN Boiler introduced advanced plate rolling equipment while standardizing the plate rolling process, to ensure better quality of the boiler drum. In the modern workshop of ZOZEN Boiler, the steel plate after pretreatment such as derusting, milling and chamfering will be transported to the drum workshop, and then rolled into the workpiece for manufacturing drum by the advanced four-axis numerical control bending machine.
