1. Product Description
Air-cooled diesel fire fighting pump set cooled by using air as air-cooled engine cooling medium. There are some advantages of this pump set, including the simple structure, light weight and low maintenance. In addition, it can keep good performance under 35 degrees without antifreeze liquid. Under the room temperature, it prevents overheating of the engine to keep working well, at the same time, it also avoid freeze crack to make sure the normal operation under the low temperature. Pump can be selected with different centrifugal pump according to the specific use of the environment.
2. Product Features
(1) Air Cooled Diesel Engine
With low energy consumption, long service life and easy maintenance, the failure rate of the air-cooled diesel engine is reduced by 27% than the water-cooled diesel engine. In addition, it can keep good performance under minus 35 degrees without antifreeze liquid. Under the room temperature, it prevents overheating of the engine to keep working well. At the same time, it also avoid freeze crack to make sure the normal operation under the low temperature. It is used in military vehicles and special purpose vehicles.
a. Low Energy Consumption
When the gas temperature of Air-cooled diesel engine is constant and the engine cylinder temperature is higher, the heat of the diesel engine emitted into the air would be less, and then the thermal efficiency becomes higher and more economy. Due to the small amount of heat transfer to the air, the cooling air flow is only 2/3 of the water cooled diesel engine. In addition, the lower power consumption of the fan also caused the lower fuel consumption.
b. The Lower Failure Rate
Practice has proved that 25% - 30 faults of water cooled diesel engine are caused by the cooling system. The failure rate of the air-cooled diesel engine is reduced by 27% than the water-cooled diesel engine, since the air cooled engine has no water cooling system. Not what machine of air-cooled diesel engine corrosion, pitting, corrosion and defects of cylinder block and cylinder head, radiator inner scale. Air-cooled diesel engine does not produce the corrosion, cavitation erosion and the scale heaped in cylinder block, cylinder head and radiator.
c. Longer Service Life
The normal service life of the diesel engine is mainly depended on the wear condition of the piston assembly and the cylinder liner. The cylinder of air cooled diesel engine is high temperature, fast heating, so it avoids acid corrosion and wear.
d. Range of Application
Air-cooled diesel engine at minus 35 ℃, it can still start and keep work reliable. There is no danger of cracking for engine body without antifreeze. Don't worry about water shortages when the air cooled diesel engine used in arid desert area. When it used in plateau with low pressure area, the cooling water boiling phenomenon won’t be happened like the water-cooled diesel engine. The cylinder body and the cylinder liner are not be damaged by the direct erosion of the cooling water.
e. Easy Maintenance
The cooled diesel engine is easy to maintain and the maintenance cost is low, because it hasn’t a full set of parts and components for water cooling system. The air-cooled diesel engine is the modular structure, one cylinder just one cylinder head, so it is more convenient to check and replacement when the malfunction of parts occurred or damaged. For example, the piston, cylinder and piston pin can be removed without disassembly of the oil pan.
(2). Digital Pressure Technology
a. Application Range of Digital Pressure Technology
Digital constant pressure diesel engine water pump is a kind of constant pressure and constant pressure variable flow device, which lock the pressure of water supply in a direct digital. Based on the intelligent control, the device can lock the pressure directly by digital, which can provide the 0~100% (maximum flow) in the 10s and the system flow can be changed according to the requirement, but the system pressure is constant. Digital constant pressure is a kind of technology that can ensure the work of pressure parameter in the design of water supply system. The technical advantage of a word - the system does not exceed pressure!
b. Working Principle of Digital Pressure Technology
Direct digital control mode to set water supply parameters (outlet pressure, differential pressure, differential pressure, flow head) in the control panel, the transducer on the water pump outlet measure the real-time parameter, by computer digital processor according to the set parameter value function transform and nonlinear correction and fuzzy PID algorithm of closed-loop control of engine speed, precise locking system parameters the (constant pressure, constant pressure, constant flow). In order to achieve the purpose of constant pressure, constant head or constant flow water supply.

The operation process finished by the program automatically
(1). Extremely cold area---- Air-cooled diesel engine at minus 35 ℃, it can still start and keep work reliable. There is no danger of cracking for engine body without antifreeze.
(2). Coastal saline alkali area---- The cylinder body and the cylinder liner can’t be damaged by the direct erosion from the cooling water.
(3). Arid desert area---- Don't worry about water shortages when the air cooled diesel engine used in arid desert area.
(4). Plateau with low pressure area----The cooling water boiling phenomenon won’t be happened like the water-cooled diesel engine.
(5). National defense and Military field ---- Air-cooled engine can adapt to the harsh environment, it is less failure, easy maintenance and does not lost the battle because of the leakage of water tank, therefore it is suitable for national defense and military field.
