Product details
The Danfoss Hydraulic Piston Pump is a high-performance hydraulic component widely used in various hydraulic systems. Here is a detailed introduction to it:
I. Working Principle
The working principle of the Danfoss hydraulic piston pump mainly relies on the reciprocating motion of the piston within the cylinder. When the piston moves in one direction, a negative pressure is generated in the cylinder, drawing in hydraulic oil; when the piston moves in the opposite direction, it compresses and discharges the hydraulic oil. This volumetric change produced by the reciprocating motion allows the hydraulic pump to continuously and stably provide hydraulic power.
II. Structural Characteristics
1. Piston and Cylinder: Both the piston and cylinder are precision-machined circular components with high mating accuracy, ensuring efficient operation of the hydraulic pump.
2. Eccentric Wheel and Drive Shaft: Some Danfoss hydraulic piston pumps use an eccentric wheel to drive the piston in reciprocating motion, while axial piston pumps utilize pistons parallel to the drive shaft that reciprocate within piston bores.
3. Check Valves: Each piston pump is typically equipped with two check valves to ensure smooth suction and discharge of hydraulic oil during piston reciprocation.
4. Flow Distribution Device: A valve-type flow distribution device is employed to ensure smooth distribution and recovery of hydraulic oil.
III. Performance Advantages
1. High Pressure: Danfoss hydraulic piston pumps can withstand high working pressures, with some series capable of reaching 48 MPa, meeting the demands of high-pressure hydraulic systems.
2. High Efficiency: Due to the precision mating of the piston and cylinder, as well as optimized flow channel design, the hydraulic pump operates with high efficiency.
3. Convenient Flow Regulation: By adjusting the stroke or speed of the piston, the flow rate of the hydraulic pump can be easily regulated to meet different working requirements.
4. Compact Structure: The compact design of Danfoss hydraulic piston pumps minimizes space occupation, facilitating installation and maintenance.
IV. Application Fields
Danfoss hydraulic piston pumps are widely used in various hydraulic systems requiring high pressure, large flow rates, and flow regulation, such as:
1. Engineering Machinery: Such as excavators and loaders, which need to withstand significant working loads and complex working environments.
2. Hydraulic Presses: Used in metal processing, plastic molding, and other processes that require stable hydraulic power.
3. Ships: For rudder control, deck machinery, and other applications on ships, requiring液压泵 to have high reliability and durability.
4. Other Fields: Including metallurgy, mining, agriculture, etc., also widely adopt Danfoss hydraulic piston pumps to meet different working demands.
V. Operating Procedures and Precautions
1. Inspection and Preparation: Before operation, check the oil level, pressure gauge, safety valve, etc., of the hydraulic pump to ensure it is in good working condition.
2. Startup and Operation: Start the hydraulic pump in the correct sequence and closely monitor its operating status. If any abnormalities are found, stop the pump immediately for inspection.
3. Shutdown and Maintenance: After shutdown, cut off the power supply, clear debris around the hydraulic pump, and perform regular maintenance to extend its service life.
In summary, the Danfoss Hydraulic Piston Pump plays an important role in hydraulic systems due to its superior performance and wide range of applications.
