Can the excavator gear pump replace the piston pump?

Gear pumps and plunger pumps have differences in their working principles, so they cannot be directly replaced. However, replacement is feasible and requires consideration of factors such as working parameters and load conditions.

A、 Can it be replaced Due to the different working principles of excavator gear pumps and plunger pumps, they can be replaced under certain conditions. Specifically, the following factors need to be considered: ① Load conditions; ② Hydraulic system parameters; ③ The operating environment of excavators. For example, when excavators are operating on flat ground, the replacement of gear pumps and plunger pumps may be feasible, but there may be some issues with replacement in complex terrain environments or high load conditions.

B、 Key points for choosing a replacement plan If it is necessary to replace the gear pump with a plunger pump or vice versa, the following points need to be considered: 1. Whether the interface and size are compatible. 2. Avoid affecting the hydraulic system. The parameters of the hydraulic system need to be consistent, including working pressure, flow rate, etc. 3. Choose based on working conditions and load requirements.

C、 The difference between excavator gear pump and plunger pump Excavator gear pumps and plunger pumps are both hydraulic pumps, but their working principles and structures differ greatly. Gear pump is a pump that drives liquid flow through the mutual meshing of gears; A plunger pump is achieved through the reciprocating motion of the plunger. Therefore, there are significant differences in their working characteristics.

D、 Conclusion Excavator gear pumps and plunger pumps have their own advantages and disadvantages and cannot be directly replaced. But under certain conditions, replacement is feasible. In order to maintain the normal operation of the equipment, various factors need to be carefully considered before choosing a replacement plan.
