When designing a hydraulic pump for a hydraulic automatic transmission, several parameters and characteristics need to be considered. Here are some key factors to keep in mind: 1. Flow: The hydraulic pump must provide sufficient flow to meet the hydraulic demands of the automatic transmission system. Flow requirements depend on factors such as the size and complexity of the transmission, the number of hydraulic circuits, and the desired shift speed. Proper sizing of the pump ensures that an adequate quantity of hydraulic oil is supplied to the system. 2. Pressure Rating: The hydraulic pump should be designed to generate the pressure required to effectively operate the automatic transmission. Pressure ratings are influenced by system requirements, including the torque capacity of the transmission, the size and type of hydraulic actuator, and the desired shift quality. Pumps must be able to deliver consistent, reliable pressure within specified ranges. 3. Pump type: Choosing the right pump type is critical for hydraulic automatic transmissions. Pump types commonly used in hydraulic transmission include gear pumps, vane pumps, and piston pumps. Each type has its advantages and limitations in terms of efficiency, noise level, size and cost. The type of pump should be selected according to the specific requirements of the transmission system. 90-R-075-KA-5-CD-60-P-3-S1-D-03-GBA-42-42-24 90R075KA5CD60P3S1D03GBA424224 90R075-KA-5-CD-60-P-3-S1-D-03-GBA-42-42-24 90R075KA5CD60P3S1D03GBA424224 90-R-075-KA-5-CD-60-P-3-S1-D-03-GBA-30-30-24 90R075KA5CD60P3S1D03GBA303024 90R075-KA-5-CD-60-P-3-S1-D-03-GBA-30-30-24 90R075KA5CD60P3S1D03GBA303024 90-R-075-KA-5-CD-60-P-3-S1-D-03-GBA-23-23-24 90R075KA5CD60P3S1D03GBA232324 90R075-KA-5-CD-60-P-3-S1-D-03-GBA-23-23-24 90R075KA5CD60P3S1D03GBA232324 90-R-075-KA-5-CD-60-P-3-C7-E-03-GBA-42-42-30 90R075KA5CD60P3C7E03GBA424230 90R075-KA-5-CD-60-P-3-C7-E-03-GBA-42-42-30 90R075KA5CD60P3C7E03GBA424230 90-R-075-KA-5-CD-60-P-3-C7-D-03-GBA-42-42-24 90R075KA5CD60P3C7D03GBA424224 90R075-KA-5-CD-60-P-3-C7-D-03-GBA-42-42-24 90R075KA5CD60P3C7D03GBA424224 90-R-075-KA-5-CD-60-P-3-C7-D-03-GBA-35-35-24 90R075KA5CD60P3C7D03GBA353524 90R075-KA-5-CD-60-P-3-C7-D-03-GBA-35-35-24 90R075KA5CD60P3C7D03GBA353524 90-R-075-KA-5-CD-60-P-3-C7-D-03-GBA-30-30-24 90R075KA5CD60P3C7D03GBA303024 90R075-KA-5-CD-60-P-3-C7-D-03-GBA-30-30-24 90R075KA5CD60P3C7D03GBA303024 90-R-075-KA-5-CD-60-P-3-C6-D-03-GBA-14-14-20 90R075KA5CD60P3C6D03GBA141420 90R075-KA-5-CD-60-P-3-C6-D-03-GBA-14-14-20 90R075KA5CD60P3C6D03GBA141420 90-R-075-KA-5-CD-60-L-4-S1-D-03-GBA-23-23-30 90R075KA5CD60L4S1D03GBA232330 90R075-KA-5-CD-60-L-4-S1-D-03-GBA-23-23-30 90R075KA5CD60L4S1D03GBA232330 90-R-075-KA-5-CD-60-L-4-C7-E-03-GBA-32-32-24 90R075KA5CD60L4C7E03GBA323224 90R075-KA-5-CD-60-L-4-C7-E-03-GBA-32-32-24 90R075KA5CD60L4C7E03GBA323224 4.
