Axial piston pumps are designed for optimum oil film thickness to ensure hydrostatic balance. Hydrostatic balance is the balance between the hydraulic forces acting on the pistons within the pump. Here are some points to consider: 1. Oil film thickness: The oil film thickness plays a vital role in achieving the hydrostatic balance of the axial piston pump. It refers to the oil layer that separates the moving parts inside the pump, such as the piston and cylinder. The optimum oil film thickness is determined by the design and operating conditions of the pump. 2. Hydrostatic balance: In an axial piston pump, hydraulic pressure is generated when the piston reciprocates in the cylinder. These forces are exerted on the piston due to the pressure differential between the inlet and outlet ports. In order to maintain hydrostatic balance, the pump is designed to minimize uneven loading on the piston by ensuring that the oil film is thick enough to distribute force evenly across the piston surface. 3. Factors affecting the thickness of the oil film: There are several factors that affect the thickness of the oil film of the axial piston pump. These include the viscosity of the hydraulic fluid used, the speed and operating conditions of the pump, and the clearances between moving parts. The pump design takes these factors into account to ensure that the oil film thickness remains within the optimum range for maintaining hydrostatic balance. 4. Benefits of Hydrostatic Balance: There are several benefits to achieving hydrostatic balance in an axial piston pump. It helps minimize wear on piston and cylinder surfaces by evenly distributing hydraulic pressure. Balanced forces also reduce vibration, noise and heat generation, thereby increasing the overall efficiency and life of the pump. 90-L-130-KP-2-CD-80-R-3-F1-F-03-GBA-29-29-24 90L130KP2CD80R3F1F03GBA292924 90-L-130-KP-2-CD-80-R-3-F1-H-03-GBA-32-32-24 90L130KP2CD80R3F1H03GBA323224 90-L-130-KP-2-CD-80-R-4-F1-H-03-GBA-42-42-24 90L130KP2CD80R4F1H03GBA424224 90L130-KP-2-DE-80-R-3-F1-F-03-GBA-42-14-24 90L130KP2DE80R3F1F03GBA421424 90-L-130-KP-2-DE-80-R-3-F1-F-03-GBA-42-14-24 90L130KP2DE80R3F1F03GBA421424 90L130-KP-2-NN-80-L-3-F1-H-00-GBA-42-42-24 90L130KP2NN80L3F1H00GBA424224 90-L-130-KP-2-NN-80-L-3-F1-H-00-GBA-42-42-24 90L130KP2NN80L3F1H00GBA424224 90L130-KP-2-NN-80-L-4-F1-F-03-GBA-35-35-24 90L130KP2NN80L4F1F03GBA353524 90-L-130-KP-2-NN-80-L-4-F1-F-03-GBA-35-35-24 90L130KP2NN80L4F1F03GBA353524 90L130-KP-2-NN-80-R-3-F1-F-03-GBA-32-32-24 90L130KP2NN80R3F1F03GBA323224 5.
