Hydraulic pumps are an essential component of many heavy-duty machines, including excavators. They are responsible for converting mechanical energy into hydraulic energy, which is used to power hydraulic systems such as cylinders, moteurs, and valves. There are different types of hydraulic pumps available in the market。 Entre-temps, includes pneumatic hydraulic pump. Dans cet article, we will explore the benefits of pneumatic hydraulic pumps and why they are a great option for excavator hydraulic pumps.
Qu'est-ce qu'une pompe hydraulique pneumatique?
UN pneumatic hydraulic pump is a type of hydraulic pump that is powered by compressed air. Il fonctionne en utilisant un piston ou un diaphragme pour générer une pression qui est ensuite utilisée pour déplacer le fluide hydraulique à travers le système.. Les pompes hydrauliques pneumatiques sont largement utilisées dans des industries telles que la construction, exploitation minière, et fabrication, où ils sont utilisés pour alimenter des machines et des équipements lourds.
Types Of Excavator Hydraulic Pumps
- Gear pumps – Often utilized as primary pumps, gear pumps have two meshing gears that trap and pressurize fluid. Reliable and efficient design.
- Piston pumps – Similar to automotive oil pumps, piston pumps use reciprocating pistons to pressurize fluid. Tend to be lower-cost option.
- Vane pumps – Vanes mounted on a rotor trap and pressurize fluid as the rotor turns. Compact, durable design suitable for tough conditions.
- Bent-axis piston pumps – Combines features of gear and piston pumps. Can operate at higher pressures and displacements.
- Variable displacement pumps – Displacement adjusts to meet the system demands, increasing efficiency and reducing heat buildup.
Roles of Hydraulic Pumps in Heavy Equipment
- Actuate work functions – Supplying pressurized fluid to hydraulic cylinders extends and retracts booms, arms, buckets and other components.
- Provide maneuverability – Pumps power hydraulic motors that drive tracks, wheels and slew rings to move and rotate the machine.
- Control attachments – Hydraulic fluid pressurized by pumps opens and closes hydraulic clamps, grippers or quick hitches.
Importance Of Proper Pump Operation & Maintenance
- Pumps must deliver adequate hydraulic flow and pressure to actuate heavy equipment functions properly while minimizing wasted energy to increase efficiency.
- Reliability through durable designs and preventive maintenance is important to avoid hydraulic pump failures that cause costly downtime.
- Adequate hydraulic cooling helps avoid dangerous heat buildup within pumps that breaks down seals, degrades fluid quality and reduces efficiency over time.
- Effective filtration removes contaminants – a leading cause of pump damage – to safeguard pump performance and longevity.
