There are several things to note when using a pulsation dampener:
Due to the harsh working environment of construction machinery, the dampener has high sealing performance, so it should be protected from dust and other debris. Also, avoid scratching or damaging the piston rod surface of the dampener with sharp tools, and do not apply paint or corrosive chemicals to the rod.
The dampener stroke should be increased based on the working stroke (approximately 0mm) to avoid installation errors that can affect the dampener's lifespan and performance.
Since the dampener is installed on construction machinery and used in outdoor environments, its service life is generally shorter, so this should be considered in the design.
The ambient temperature range for the dampener is -35°C to +60°C.
The dampener should not be subjected to lateral or oblique forces during operation, as it can cause eccentric wear and premature failure. This is an important consideration during the design phase.
For lightweight doors without locking devices, ensure that the connection between the dampener's fixed pivot point and the active pivot point rotates around the center of rotation when the door is closed. The application of hydraulic dampeners in structural engineering such as buildings, bridges, and railways is rapidly expanding.
The dampener should not have relative motion in both the closed and working states, and its continuous extension should be controlled within a specified range.
Construction machinery doors, such as machine covers, are usually heavy. When selecting a dampener, consider using one with a safety device to avoid potential safety hazards caused by dampener failure.
The dampener should not be used as a limiting device. Additional limiting devices, typically rubber stoppers, should be added to restrict the position.
These are the points to be noted when using a pulsation dampener. Long-term users often develop their own preventive measures, providing a valuable way for knowledge sharing. The application of hydraulic dampeners in structural engineering such as buildings, bridges, and railways is rapidly expanding.
