How to size hydraulic gear pumps

How important is it to provide dimensions when manufacturing hydraulic gear pumps:

Hydraulic gear pump is the power element in the hydraulic transmission system, which is driven by the prime mover, takes the mechanical energy from the output power of the prime mover and converts it into the pressure energy of the fluid to provide the system with pressurized fluid. Then, at the place where work needs to be done, the actuating element converts the fluid pressure energy into mechanical energy and outputs it to the gear pump. Therefore, reasonable hydraulic gear pump size design and selection for the performance of the hydraulic system and the use of the effect is very important.

Hydraulic gear pump size development:

Hydraulic gear pump size refers to the design, manufacture and use of hydraulic gear pumps in the process, the provisions of its size range, tolerances, inspection methods and technical requirements and other aspects of the national standard. The development of hydraulic gear pump size is to ensure the quality and performance of hydraulic gear pumps, while making different manufacturers of hydraulic gear pumps have interchangeability.

Then we need to confirm what size parameters before manufacturing hydraulic gear pumps?

1. Gear diameter

Gear diameter is one of the important parameters of the internal gear pump, which determines the pump flow and pressure. Usually, the larger the gear diameter, the higher the flow rate, but the lower the pressure. Conversely, the smaller the gear diameter, the smaller the flow rate, but the higher the pressure. Therefore, in the design of gear pumps, according to the specific requirements to determine the gear diameter.

2. gear teeth

Gear teeth is another important parameter of the gear pump, which determines the size of the gear and the number of teeth. Usually, the larger the gear module, the smaller the number of teeth, the larger the gear. Conversely, the smaller the gear module, the more teeth, the smaller the gear. In the design of internal gear pumps, according to the specific requirements to determine the gear module.

3. Pump body length

Pump body length is another important parameter of the internal gear pump, which determines the pump flow and pressure. Usually, the longer the length of the pump body, the greater the flow, but the lower the pressure. Conversely, the shorter the length of the pump body, the smaller the flow rate, but the higher the pressure. In the design of internal gear pumps, need to determine the length of the pump body, according to the specific requirements of use.

4. Shaft diameter

Shaft diameter is another important parameter of the internal gear pump, which determines the pump's load-bearing capacity and stability. Usually, the larger the shaft diameter, the stronger the carrying capacity of the pump, the better the stability. Conversely, the smaller the shaft diameter, the weaker the carrying capacity of the pump, the worse the stability. In the design of internal gear pumps, you need to determine the shaft diameter according to the specific requirements of use.

Sample graph:

The application of hydraulic gear pump size can be from the following aspects

1. Hydraulic gear pump design and manufacturing: hydraulic gear pump size can be used as a basis for hydraulic gear pump design and manufacturing, to ensure that the hydraulic gear pump dimensions and tolerances in line with the requirements, so as to ensure that the performance and quality of hydraulic gear pumps.

2. Hydraulic gear pump selection: hydraulic gear pump size can be used as a basis for the selection of hydraulic gear pumps, to help users choose the appropriate hydraulic gear pumps, so as to ensure that the performance of the hydraulic system and the use of the effect.

3. Hydraulic gear pump maintenance and overhaul: hydraulic gear pump size can be used as a hydraulic gear pump maintenance and overhaul basis to help users carry out maintenance and overhaul of hydraulic gear pumps, thereby extending the service life of hydraulic gear pumps.
