What issue can occur in an axial piston pump with variable displacement if the flow or pressure is low?

In an axial piston pump with variable displacement, maintaining proper flow and pressure is crucial for its operation. Each of the provided issues can significantly impact the pump's performance, particularly if either the flow or pressure is low.

When tensions arise in hydraulic systems, the flow or pressure might drop due to several contributing factors. If the pressure or load sensor is not properly calibrated, it can lead to inadequate signal feedback, causing the system to react improperly to changes in demand. This miscalibration can prevent the pump from adjusting its displacement accurately, leading to low output conditions.

A blockage in the pilot port to the load sensor or compensator can impede the system's ability to monitor and control the fluid flow. If flow to the compensator is restricted, it might not receive the necessary information to regulate displacement effectively. This can result in inefficient pumping action, contributing to low flow and pressure conditions.

Additionally, a broken load sensor or compensator spring may hinder the mechanical ability of the compensator to respond to system demands. If the spring is dysfunctional, it cannot maintain the correct positioning for displacement control, which directly affects the performance of the pump under varying load conditions.

Given that all these factors can lead to decreased flow or pressure in the system, it's accurate to say
