The membrane tube wall racker is an important part of the common boilers, such as ZOZEN SZL series biomass-fired boiler, SZS series gas/oil-fired boiler and circulating chain grate boiler. The racker can ensure the air tightness of the boiler and improve the thermal efficiency.
According to different boiler capacities, the boiler delivery can be divided into three ways, package delivery, assembled delivery and delivery in bulk. The video shows the important pressure part --- boiler drums.
During the assembly process of ZOZEN WNS gas-fired boiler, the workers will assemble the threaded smoke tube produced in batches one by one according to the specifications. Then, the professional welder completes the automatic welding of the tube sheet.
For more than 30 years, ZOZEN Boiler has persisted in innovative research and development. The application of ZOZEN automatic CNC tube bending production line has greatly improved the working efficiency and quality, and provided a powerful guarantee for creating first-class products.
There's a growing demand for the heating boilers due to the season. Previously, ZOZEN Boiler cooperated with a heating company in Tianjin to provide three sets of 29MW packaged gas-fired hot water boilers, which accelerated the completion of the project.
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 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.
