HLT Series Diesel-Powered Mobile Screw Air Compressor (Dual-Purpose for Sandblasting & Construction, Field Operation Air Source Equipment)

This machine features a diesel engine directly driving a twin-screw compressor unit, equipped with a wheeled mobile chassis and a microcomputer intelligent control system, capable of independent operation without external power supply. The 0~100% infinitely variable air flow control combined with automatic diesel engine throttle adjustment enables on-demand air supply and maximum fuel savings. With power coverage from 37 to 300kW, air delivery from 6.0 to 30m³/min, and pressure from 0.7 to 2.2MPa, it is widely used in sandblasting rust removal, mining, tunnel construction, highway and railway construction, and other field operation scenarios without power supply—the ideal air source equipment for modern field mobile construction with powerful performance, high efficiency, and adaptability to harsh environments.

This HLT series diesel mobile air compressor is a high-efficiency screw air compressor powered by a diesel engine and equipped with a wheeled mobile chassis, specifically designed for field operations without external power supply and mobile working scenarios. The core working principle is: the diesel engine drives the screw compressor unit directly through a high-elasticity coupling; two asymmetrical screw rotors perform continuous, smooth meshing compression inside the compression chamber, converting the chemical energy of diesel combustion into mechanical energy, and then into gas pressure energy, providing stable, clean compressed air for various pneumatic equipment and construction processes. As the ideal mobile air source for sandblasting machines, rock drills, jackhammers, pneumatic tools, and other equipment, this HLT diesel mobile air compressor stands out with its significant advantages of powerful performance, no external power requirement, exceptional mobility, and adaptability to harsh environments, making it the preferred air supply equipment for highway and railway construction, mining, water conservancy engineering, shipbuilding, urban construction, petrochemical, and other field operation scenarios.

In terms of manufacturing quality and structural integrity, this HLT diesel mobile air compressor features a large-diameter screw rotor design with patented profiles. The compressor unit and diesel engine are directly coupled via a high-elasticity coupling with no intermediate speed-increasing gear, with the compressor speed matching the diesel engine speed (not exceeding 2400r/min), resulting in higher transmission efficiency, better reliability, and longer service life. The diesel engine is selected from renowned domestic and international brands such as Cummins and Yuchai, meeting National Phase II/Euro Phase II emission requirements, with powerful performance, low fuel consumption, and a nationwide after-sales service network. The air flow control system is simple and reliable, automatically adjusting the intake air volume from 0 to 100% based on air demand, while simultaneously adjusting the diesel engine throttle to maximize fuel savings. A microcomputer intelligent monitoring system continuously tracks operating parameters including discharge pressure, discharge temperature, diesel engine speed, oil pressure, coolant temperature, and fuel tank level, with automatic alarm and shutdown protection functions. Multi-stage air filters suit dusty working environments, multi-stage fuel filters accommodate domestic fuel quality conditions, and oversized oil-water coolers suit high-temperature and plateau environments. The entire unit features an enclosed box-type structure with low noise and low vibration design; spacious maintenance doors provide easy access to all serviceable components, making maintenance of air filters, oil filters, fuel tanks, batteries, and oil coolers convenient and reducing downtime. The mobile chassis features a two-wheel or four-wheel design with pneumatic tires and a tow bar, allowing flexible movement even in harsh terrain conditions; each compressor is equipped with lifting rings for safe and convenient hoisting and transportation.

The performance advantages and application value of this HLT diesel mobile air compressor are exceptionally prominent. First, independent power, no external power required – the diesel engine provides self-contained drive, making it particularly suitable for field operations, mountainous areas, tunnels, remote construction sites, and other locations without power supply or with unstable power. Second, powerful performance and wide adaptability – power coverage from 37 to 300kW, air delivery up to 30m³/min, and discharge pressure up to 2.2MPa, meeting various air demand requirements from light to heavy loads. Third, intelligent energy-saving operation – 0~100% infinitely variable air flow control combined with automatic diesel engine throttle adjustment enables on-demand air supply and maximum fuel savings. Fourth, high reliability and long service life – the screw compressor has few components and no wearing parts, ensuring reliable operation and long service life, with overhaul intervals reaching 40,000 to 80,000 hours. Fifth, adaptability to harsh environments – multi-stage filtration systems, oversized coolers, and high-temperature resistant design suit dusty, high-temperature, plateau, and other harsh field environments.

In terms of application scope, this HLT diesel mobile air compressor is widely used in sandblasting rust removal, highway and railway construction, mining, tunnel construction, water conservancy engineering, shipbuilding, urban construction, energy development, military support, petrochemical pipeline construction, and other mobile operation scenarios. In the sandblasting rust removal field, it provides continuous, stable high-pressure airflow for mobile sandblasting machines, ensuring the sandblasting surface treatment grade reaches Sa2.5 or above; in mining and tunnel construction, it drives rock drills, jackhammers, and other equipment for drilling and rock-breaking operations. This HLT series diesel mobile air compressor is an indispensable core power air source equipment for modern field mobile construction.
