Application: Large-scale infrastructure projects
In large infrastructure projects, whether it is tunnelling, bridge construction or port terminal construction, stable, clean and high-flow compressed air is indispensable for the continuous operation of pneumatic tools, the stable energy supply of concrete spraying equipment and the efficient operation of ventilation and dust removal systems. The stability of the air source directly affects the project progress, construction safety and project costs. The 250 HP
Screw Air Compressor from ZAKF, a brand of Dongguan Jubilee Compressor Fittings Co., Ltd, has become the preferred air source equipment for many large-scale infrastructure projects due to its high reliability, energy-saving economy and strong environmental adaptability.
A high-altitude tunnel project of Sichuan-Tibet Railway is a key transportation infrastructure project of China's “14th Five-Year Plan”, with complex terrain, harsh geological conditions and tight schedule. The air compressor used at the beginning of the project could not adapt to the high-altitude low-oxygen environment, and frequently appeared the problem of insufficient exhaust volume and unstable air pressure, which led to a significant decline in the operational efficiency of rock drills, concrete sprayers and other equipment, and the construction progress of part of the tunnel was lagging behind, and the additional costs incurred due to the equipment problems amounted to 800,000 yuan per month. Mr. Wang, the technical leader of the project, said frankly: “The complex construction environment is extremely demanding on the equipment, and the unstable air source seriously hindered the progress of the project, so we urgently need to find a reliable solution.”
With the introduction of the ZAKF 250 HP screw air compressor at
, the construction problems were solved. The ZAKF 250 HP screw air compressor is a direct-drive
Screw Compressor with 185kW of power that can achieve stable exhaust pressure (0.8 - 1.0MPa) even at high altitude, and with a three-stage filtration system, it provides a clean and stable air source for all kinds of pneumatic equipment. The simple and reliable structural design of the equipment greatly reduces the failure rate under the harsh conditions of low temperature and dust, and extends the maintenance cycle, shortening the monthly downtime for maintenance from 15 hours to 2 hours, saving maintenance costs of more than 600,000 yuan. In addition, compared with the previous equipment, this model has a significant energy saving effect, reducing the monthly electricity bill by about 30%. The stable gas supply has enabled the tunnel excavation and concrete pouring work to move forward efficiently, increasing construction efficiency by 60% and putting the project back on track. Mr. Wang said excitedly, “The stable performance of the ZAKF air compressor in the extreme environment exceeded expectations, which ensured the smooth progress of the project and laid a solid foundation for us to complete the construction task on time.”
In addition to excellent performance, the 250HP frequency screw compressor has lower initial investment cost and easier maintenance than the inverter model, which meets the needs of large infrastructure projects for cost control and efficient construction. Intelligent controllers monitor the operating status of the equipment in real time, balancing energy saving and intelligent management needs, and further guaranteeing the stable operation of the equipment. Dongguan Jubilee Compressor Parts Co., Ltd. provides comprehensive after-sales service, including a one-year warranty, sufficient stock of original spare parts, as well as a team of professional engineers to quickly respond to the needs of installation and commissioning, regular maintenance and fault repair, for the smooth progress of the infrastructure project throughout the escort.
