THE OPTIMUM PISTON COMPRESSOR
As one of the earliest compressor designs, piston compressors are among the most versatile and extremely efficient compressors. Their strengths:
- Because of their basic design, limited number of working parts and straightforward working principle, piston compressors are the best solution when compressed air is needed in harsh conditions.
- Simple maintenance thanks to easily accessible parts for servicing.
- No need for special treatment (oil separation) nor oil filtering as there is no direct contact with oil.
- High reliability and increased lifetime due to limited risk of condensation formation as a result of the piston compressor’s low mass.
- Piston compressors can operate in a very wide range of working pressures. Maximum working pressure for the Atlas Copco L series is 30 bar (435 psi).
Высокая надежность
Благодаря уникальной, прочной конструкции и сочетанию качественных материалов, компрессоры LT отличаются повышенной производительностью и увеличенным сроком службы. Конструкция вентилятора позволяет добиться оптимального охлаждения потока воздуха.
Простое обслуживание
Легкий и простой доступ ко всем компонентам и узлам обслуживания.
Экономия занимаемого пространства
Блок компрессора, непосредственно соединенный с двигателем, производится с использованием легковесных материалов. Это обеспечивает его превосходное охлаждение, делая компрессор идеальным решением в условиях ограниченных пространств.
Низкие текущие расходы
Затраты на эксплуатацию ограничены, а благодаря использованию высокопрочных элементов, компрессор отличается длительным сроком службы.
The piston compressor moves a piston forward in a cylinder via a connecting rod and crankshaft.
Двухступенчатое сжатие
Filtered air is entered into one cylinder only. This low-pressure cylinder feeds the second (high-pressure) cylinder which increases the pressure to the required level of 15, 20 or 30 bar (218, 290 or 435 psi). In between the 2 stages, an intercooler brings down the compression temperature resulting in increased compression efficiency.
Расположение привода
The standard drive arrangement is direct drive with electrical motor. However, the compressor block can also be directly driven by a hydraulic motor, diesel or petrol motor and a kit is available for belt drive arrangement.
Электрорегулировка
The standard electrical regulation occurs by means of a pressure switch that starts/stops the compressor at pre-set pressures. All units are also supplied with an overload relay. In the standard models, the cylinder heads are always de-pressurized if the unit is stopped via the pressure switch. On units with Direct on Line (DOL) start this is done through the pneumatic unloader located inside the pressure switch box. Units with Y/D start are supplied with Industrial Unloader Valve and solenoid valve to de-pressurize the cylinder heads both at stopping and starting ofthe unit.Starting the compressor without back pressure in combination with the special Y/D motor dramatically reduces start-up currents. A cubicle is needed to manage the motor running between Y and D and to control the Industrial UnloaderValve. Please referto the model overview for more details.
1. Automotive style cylinders
made of high silicium aluminium alloy with low tolerance finishing resulting in exceptional lubrication, extremely low clearance and minimized oil carry-over.
2. Direct drive
No transmission losses
3. Inlet/outlet disc valves
unique and simple to service, the valves are stainless steel flexible annular discs.
4. Cooling fan
high capacity cooling fan contained in protective fan cowl, providing optimal direct cooling of the cylinders and aftercooler/intercooler
5. Aftercooler/intercooler
combined finned die-cast aluminum outlet cooler and finned copper aftercooler pipe for single-stage units and additional intercooler for two-stage units.
6. Air intake filter
rapid replacement, large surface air intake filter, reducing contaminants and prolonging compressor life
7. Heavy-duty ball bearings
selected for high duty and long lifetime.
8. Die-cast aluminum crankcase & finned cylinder heads
featuring high cooling characteristics, the crankcase and cylinder heads provide long lifetime and efficient operation.
9. Industrial check valve or unloader valve
designed to withstand extreme conditions and high working pressures. The unloader valve is used in combination with a Y/D starter and special motor to reduce starting torque. This results in longer compressor and motor lifetime as well as limited strain on your electricity supply net.
10. Venturi silencing intake
guaranteed low noise levels
11. Sound muffler
used on units with an unloader valve. Low noise levels are maintained at all times.
12. V-design of compressor block
the dynamically balanced crankshaft and heavy-weight cast iron cooling fan reduce vibration.
