Swash plate piston pumps and inclined axis piston pumps are two common types of hydraulic piston pumps that are similar in some respects but also have many differences. This article will introduce the difference between the swash plate piston pump and the inclined axis piston pump in detail from the aspects of structure, working principle and performance characteristics. 1. Structure There are significant differences in the structural design of swash plate piston pumps and inclined axis piston pumps. The swash plate plunger pump is a plunger pump that uses a swash plate mechanism as the rotational support of the plunger. The main components of the pump include housing, swash plate, plunger, etc. The swash plate is fixed on the pump shaft, and the plunger drives the plunger to rotate through the tilting motion of the swash plate. The main advantages of the swash plate plunger pump are simple structure, easy manufacture and maintenance, and relatively small volume and weight. The inclined-axis plunger pump is a plunger pump that uses an inclined-axis mechanism as a rotary support for the plunger. The pump is composed of housing, inclined shaft, plunger and so on. The plunger drives the plunger to rotate through the rotation of the inclined shaft. In comparison, the structural design of the inclined-axis plunger pump is more complicated, and the manufacturing and maintenance are more difficult than the swash-plate plunger pump. Inclined-axis plunger pump is a high-precision compressive fluid delivery facility, which is composed of shell, inclined shaft, plunger and other parts. Its working principle is to drive the plunger to rotate through the rotation of the inclined shaft, and then to decompress and suck fluid. Compared with the swash plate piston pump, the inclined axis piston pump has a more complex structural design, but it also has higher flow and stability. 90-L-075-HF-5-BC-60-L-4-C7-E-03-GBA-30-30-24 90L075HF5BC60L4C7E03GBA303024 90L075-HF-5-BC-60-S-4-C7-E-03-GBA-30-30-24 90L075HF5BC60S4C7E03GBA303024 90-L-075-HF-5-BC-60-S-4-C7-E-03-GBA-30-30-24 90L075HF5BC60S4C7E03GBA303024 90L075-HF-5-BC-80-L-3-S1-E-03-GBA-29-29-24 90L075HF5BC80L3S1E03GBA292924 90-L-075-HF-5-BC-80-L-3-S1-E-03-GBA-29-29-24 90L075HF5BC80L3S1E03GBA292924 90L075-HF-5-BC-80-R-4-S1-D-03-GBA-35-35-24 90L075HF5BC80R4S1D03GBA353524 90-L-075-HF-5-BC-80-R-4-S1-D-03-GBA-35-35-24 90L075HF5BC80R4S1D03GBA353524 90L075-HF-5-BC-80-S-3-C7-D-03-GBA-45-45-24 90L075HF5BC80S3C7D03GBA454524 90-L-075-HF-5-BC-80-S-3-C7-D-03-GBA-45-45-24 90L075HF5BC80S3C7D03GBA454524 90L075-HF-5-BC-80-S-3-C7-E-03-GBA-35-35-24 90L075HF5BC80S3C7E03GBA353524 First of all, the pump uses an inclined shaft mechanism as the support for the plunger rotation, which can run under high strength and high speed conditions, with higher speed and stronger power, which can greatly improve the working efficiency of the pump. Secondly, because the plunger of the inclined axis plunger pump is driven to rotate by the rotation of the inclined axis, the pump has higher precision and stronger stability, making it more suitable for hydraulic system applications. In addition, the inclined axis plunger pump also has the advantages of high pressure, low noise, low vibration and energy saving, and can be widely used in various industries. However, the structural design of the inclined-axis plunger pump is more complicated, and the manufacturing and maintenance are more difficult than the swash-plate plunger pump, requiring a higher technical level and more advanced processing technology. Therefore, before using this type of pump, the cost, performance and service life of the pump must be carefully evaluated to ensure that the pump can achieve the expected use effect. All in all, the inclined-axis plunger pump has high precision, stability and power, and is a high-performance decompression fluid delivery facility. Despite its relatively high structural complexity, with the continuous development of modern technology, the application prospects of inclined-axis piston pumps in hydraulic systems are still very broad. 2. Working principle There is a certain difference in the working principle between the swash plate plunger pump and the inclined axis plunger pump. The swash plate plunger pump drives the plunger to rotate through the tilting movement of the swash plate, so that the low-pressure oil is sucked into the pump chamber and the high-pressure oil is discharged to achieve variable output. When the inclination angle of the swash plate increases, the plunger will automatically adjust the position of rotation to control the output flow. The swash plate plunger pump is suitable for small and medium power flow systems, and can meet the needs of hydraulic transmission under low and medium pressure. The inclined shaft plunger pump drives the plunger to rotate through the rotation of the inclined shaft, and sends the oil to the high pressure oil circuit. The output flow of the inclined shaft plunger pump is affected by the axial movement of the inclined shaft. When the inclined axis is displaced, the plunger will also be displaced accordingly, so as to realize variable output. Inclined axis plunger pumps are suitable for hydraulic transmission systems under high power and high pressure. 90-L-075-HF-5-BC-80-S-3-C7-E-03-GBA-35-35-24 90L075HF5BC80S3C7E03GBA353524 90L075-HF-5-BC-80-S-3-S1-E-03-GBA-42-42-24 90L075HF5BC80S3S1E03GBA424224 90-L-075-HF-5-BC-80-S-3-S1-E-03-GBA-42-42-24 90L075HF5BC80S3S1E03GBA424224 90L075-HF-5-CD-60-S-3-C7-C-03-GBA-35-35-24 90L075HF5CD60S3C7C03GBA353524 90-L-075-HF-5-CD-60-S-3-C7-C-03-GBA-35-35-24 90L075HF5CD60S3C7C03GBA353524 90L075-HF-5-CD-80-R-3-C7-D-06-GBA-42-42-24 90L075HF5CD80R3C7D06GBA424224 90-L-075-HF-5-CD-80-R-3-C7-D-06-GBA-42-42-24 90L075HF5CD80R3C7D06GBA424224 90L075-HF-5-CD-80-S-3-C7-E-03-GBA-42-42-24 90L075HF5CD80S3C7E03GBA424224 90-L-075-HF-5-CD-80-S-3-C7-E-03-GBA-42-42-24 90L075HF5CD80S3C7E03GBA424224 90L075-HF-5-CD-80-S-4-C7-D-03-GBA-35-35-24 90L075HF5CD80S4C7D03GBA353524 3. Performance characteristics There are also huge differences in performance characteristics between swash plate and inclined axis piston pumps. The swash plate plunger pump has the characteristics of simple structure, light weight, easy manufacture and maintenance, and its oil discharge oil circuit is short in length, and the pressure pulsation is small, so it has low noise, good stability and high reliability. In terms of service life, the life of the swash plate piston pump is longer than that of the inclined axis piston pump. The inclined-axis plunger pump is suitable for hydraulic transmission systems under high power and high pressure. Its output flow is stable and the flow fluctuation is small, so it has good uniformity. However, the manufacture and maintenance of inclined-axis piston pumps are more difficult than swash-plate piston pumps. In short, although swash plate and inclined axis piston pumps are two common types of hydraulic piston pumps, there are significant differences between them. Selecting the appropriate plunger pump type according to actual needs will help improve the efficiency and reliability of the hydraulic transmission system.
