A2F Series Hydraulic Piston Pump A2F107/125/160/180/200/225/250/355/500/915/1000 W2P2R2P3W2Z2 A2F63W2P2

A2F63W2P2 is a type of A2F series inclined shaft axial piston fixed displacement pump/motor, commonly used in hydraulic transmission systems of fishing machinery, construction machinery and other fields. The following is a comprehensive analysis from multiple aspects such as model and attributes:
Model Analysis
The meaning of model segments
A2F stands for Inclined Shaft Axial Piston fixed Displacement Pump/Motor, which is a reversible hydraulic component. It can achieve static pressure transmission in both open and closed circuits and has both pump and motor working modes
63 indicates a rated displacement of 63 mL /r. This parameter determines its flow output capacity per unit speed when used as a pump, as well as its speed and torque-related characteristics when used as a motor
W is the supplementary code for the rotation direction. In accordance with the A2F series marking standards, it usually corresponds to a specific reverse rotation setting (different from the conventional R corresponding to clockwise, which mostly refers to the counterclockwise rotation direction observed from the drive shaft end).
2 is the installation specification code, corresponding to specific flange standards and shaft extension structures, and is compatible with the equipment installation interface and power connection requirements of this displacement specification
P2 is an accessory and seal compatibility code, covering parameters such as seal material and oil circuit interface details, and is used to match the assembly sealing and pipeline connection requirements of hydraulic systems under specific working conditions
Product attributes
Core parameters: The rated working pressure can reach up to 35MPa, and the maximum working pressure can temporarily reach 40MPa. The rated flow rate is directly proportional to the driving speed. Calculated based on the speed under common operating conditions, the flow rate is suitable for the requirements of medium and small power hydraulic systems. The input shaft is compatible with the motor of the corresponding power and adopts the standard key connection form. When used as a motor, the output torque increases as the pressure difference between the inlet and outlet increases.
Adaptation to environment and medium: Compatible with L-HM32, 46, 68 high-pressure anti-wear hydraulic oil, and partially compatible with fire-resistant hydraulic oil; The working oil temperature range is -25 ℃ to 80℃. If it exceeds this range, the oil needs to be heated or cooled. The sealing material is mostly fluororubber (FKM), which is suitable for the sealing requirements of conventional and medium to high-temperature working conditions.
Application scenarios: Due to its compatibility with fishing machinery and other equipment, it is often used in the hydraulic drive systems of fishing machinery. It can also be applied in open or closed hydraulic circuits of small and medium-sized construction machinery, mining auxiliary equipment, light industrial machinery, etc.
The working principle of this component is consistent with that of other models in the A2F series. It achieves energy conversion based on an inclined shaft axial piston structure and is divided into two operating conditions: pump and motor.
Pump operating condition: The motor drives the drive shaft to rotate, and through the connecting rod, it drives the plunger and the cylinder to rotate synchronously. Because the cylinder block axis forms a certain Angle with the drive shaft axis, the plunger will perform a reciprocating motion within the cylinder block. When the plunger retracts and expands the volume of the cylinder cavity, hydraulic oil is drawn in through the distribution plate. When the plunger moves forward to compress the volume, the hydraulic oil is pressurized and discharged through the distribution plate, converting mechanical energy into hydraulic energy. The flow rate is directly proportional to the driving speed and displacement.
Motor operating conditions: After high-pressure hydraulic oil enters the cylinder cavity, it drives the plunger to move. The hydraulic pressure is transmitted to the drive shaft through the connecting rod. With the help of the inclined shaft structure, a rotational torque is generated, which drives the drive shaft to rotate and output mechanical energy. The low-pressure oil that has completed work is discharged through the distribution plate. The output speed is directly proportional to the input flow rate, and the output torque is positively correlated with the difference in oil pressure.
Product features
Low noise and high efficiency: As a high-speed and low-noise hydraulic component, it has minimal mechanical vibration and noise during operation, making it suitable for equipment with high requirements for working condition noise. It adopts a spherical distribution plate structure, featuring high volumetric efficiency and total efficiency, as well as low energy loss.
Reliable structure: The inclined shaft design ensures uniform force distribution. The drive shaft can withstand certain radial loads, and the internal bearings are designed with wear resistance to extend service life. The shell is made of high-strength material, with strong impact resistance, and is suitable for the usage requirements of outdoor or complex working conditions, such as fishing machinery.
Strong adaptability: Compact structure, high power density, and small installation space requirements; A variety of accessory codes are adapted to different sealing and interface requirements, and can flexibly match the assembly requirements of different hydraulic systems.
Installation and Operation
Installation specifications: When installing, use flanges of corresponding specifications for fixation. The bracket must have sufficient rigidity to avoid resonance during operation. It is connected to the prime mover through an elastic coupling. The coaxiality error should be controlled within 0.1mm. It is strictly forbidden to hammer the shaft end to avoid damaging the internal parts. It should be installed below the liquid level of the oil tank first. If it needs to be installed above the oil tank, the oil suction height must not exceed 500mm. At the same time, ensure that the oil leakage port is unobstructed and positioned higher than the component body to guarantee that the housing is filled with oil for lubrication.
Operation and maintenance: The filtration accuracy of the hydraulic oil should reach 5-10 μm to prevent impurities from wearing down precision components such as the plunger and distribution plate. The allowable pressure of oil leakage inside the shell shall not exceed 0.1MPa, and it is necessary to ensure that the oil drainage path is not blocked. Before starting, all the air in the oil circuit must be completely drained. When starting at low temperatures, the oil should be preheated first to avoid starting wear caused by too high viscosity. During operation, the oil temperature and contamination level should be checked regularly.
