Transient vibration of an axial piston pump refers to the dynamic behavior of pump components during startup, shutdown or sudden changes in operating conditions. This type of vibration typically occurs due to rapid acceleration or deceleration of moving parts within the pump, resulting in transient forces and responses. During transient events, pumps experience unstable flow and pressure conditions, which can cause the following types of vibration: 1. Pulse excitation: When the pump starts or stops suddenly, the speed and direction of the piston, swash plate and other moving parts will change suddenly. Sudden changes in these motions create pulsed excitations that cause momentary vibrations in the pump components. 2. Fluid Hammer: Rapid flow changes can cause pressure fluctuations and water hammer effects within the pump and associated piping. The liquid hammer produces high-intensity pressure waves that can cause significant vibration in the pump and connected systems. 3. Resonance effect: Transient vibration may also be caused by the natural frequency of the pump or resonance phenomenon. If the operating conditions of the pump match its natural frequency, this can cause vibration amplification, which can lead to component fatigue or failure. 4. Cavitation effects: During rapid pressure changes, there is a risk of cavitation - the formation and collapse of vapor bubbles in the fluid. Vibrations caused by cavitation can damage pump components, causing corrosion or pitting of surfaces exposed to cavitation.

Damping system: Implementing a damping system, such as a shock absorber or shock absorber, can help absorb and dissipate energy generated during transient events, thereby reducing vibration amplitude. 2. Control strategy: Complex control strategies can be employed to gradually increase or decrease the speed of the pump during startup and shutdown, minimizing sudden changes and associated vibrations. 3. Avoid resonance: Designing the pump and its installation system to avoid resonance with any possible excitation frequency can prevent excessive vibration amplification. 4. Pump and system design: It is critical to ensure that the pump and its associated components are designed to withstand transient events. Robust materials, proper clearances and reinforced construction increase pump durability under dynamic conditions. 5. Fluid Handling: Proper fluid handling practices, such as reducing flow fluctuations and avoiding sudden pressure changes, help prevent fluid hammer effects and cavitation.

Pre-start check: Before starting the pump, a pre-start check must be performed to ensure that the pump has started properly and is ready to run. This helps prevent potential problems that could arise during start-up, reducing the possibility of transient vibrations. 7. Monitoring and maintenance: Regular monitoring of pump performance, including vibration, can help detect any changes or abnormalities that indicate potential problems. Implementing a proactive maintenance program can identify and correct problems in a timely manner before they escalate into more serious problems. 8. Anti-cavitation measures: To minimize the risk of cavitation-induced vibration, consider anti-cavitation measures. These measures may include modifying the pump design to reduce differential pressure or using materials that are more resistant to cavitation. 9. System damping: Adding damping elements to the pump system, such as elastic brackets or isolation pads, can help dampen vibration and reduce its impact on surrounding structures or equipment. 10. Computational Fluid Dynamics (CFD) Analysis: Leveraging CFD analysis during the pump design phase can help identify potential flow-related issues, such as areas prone to cavitation or pressure fluctuations, enabling targeted design improvements. 11. Surge suppressor: In systems with large pressure fluctuations, surge suppressors or accumulators can be used to smooth pressure changes and reduce the impact on pumps and related components.
