Excessive pressure buildup
Excessive pressure buildup is a term used to describe the accumulation of pressure beyond safe operating limits in an accumulator system. When the pressure in the system exceeds the recommended level, it can lead to overpressurization, which poses a risk to the equipment and personnel.
The buildup of excessive pressure can be caused by various factors, such as a malfunctioning relief valve, a blocked discharge line, or a failure of the pressure relief device. When the pressure relief device fails to open at the specified pressure, the pressure in the accumulator continues to rise, causing an overpressurization situation.
Effects of overpressurization
Overpressurization can have severe consequences for the system and its components. The high pressure can cause damage to the accumulator, including bursting or deformation of the housing. It can also lead to leakage or rupture of hoses, seals, and fittings.
Moreover, overpressurization poses a safety risk to personnel working in the vicinity of the system. The sudden release of stored energy due to an explosive burst or rupture can cause serious injuries or even fatalities.
Solutions
To prevent excessive pressure buildup, regular maintenance and inspection of the accumulator system are crucial. This includes checking the relief valve for proper functioning and ensuring that the discharge line is clear of any obstructions.
It is also recommended to install pressure gauges and monitoring systems to continuously monitor the pressure levels in the system. This allows for early detection of any pressure abnormalities and enables prompt action to prevent overpressurization.
In case of overpressurization, it is important to immediately shut down the system and isolate it from the power source. Any damaged components should be repaired or replaced before the system is reactivated.
Overall, proactive measures and adherence to safety guidelines can help mitigate the risk of excessive pressure buildup and ensure the safe operation of accumulator systems.
Overpressurization
Overpressurization of an accumulator occurs when there is excessive pressure stored in the system, leading to an increased risk of failure and potential hazards.

Stored pressure
The accumulator in a hydraulic system stores pressure that can be used to supplement or maintain system pressure during periods of high demand. However, when the accumulator becomes overcharged, excessive pressure can build up, leading to overpressurization.
The stored pressure in an accumulator is essential for providing quick and responsive power during sudden demands. It acts as a temporary energy reserve that can be released to meet peak demands and stabilizes system pressure throughout operation.
However, if the accumulator is not properly maintained or if there is a malfunction in the system, the stored pressure can become excessive. This overcharge can result in overpressurization, which can lead to system failures, leaks, and even catastrophic accidents.
To prevent excessive pressure and overpressurization, regular maintenance and monitoring of the accumulator is necessary. This involves inspecting the accumulator for any signs of wear, checking the pressure levels, and ensuring that the accumulator is properly sized for the system requirements.
In case of overpressurization, immediate action must be taken to relieve the excess pressure. This can be done by venting or draining the accumulator and identifying and fixing the underlying cause of the problem.
By properly maintaining the stored pressure in an accumulator and ensuring it is within safe limits, the risk of overpressurization and potential system failures can be minimized, ensuring the smooth and efficient operation of the hydraulic system.
