How To Determine The Form Of The Hydraulic Cylinder Buffer Mechanism
The determination of the buffer mechanism for a hydraulic cylinder depends on the specific requirements for the change in piston linear speed during the working process. Here are some considerations for selecting a suitable buffer mechanism:
Deceleration process requirements: If the deceleration process requires minimal pulses or smooth deceleration, buffer mechanisms such as milled groove type or stepped buffer mechanisms can be used.
Strict deceleration requirements: If stricter deceleration requirements are in place, buffer mechanisms closer to the constant deceleration type may be needed. Examples include porous cylinders or porous plunger types.
Tolerating pulses during deceleration: If the hydraulic cylinder can tolerate some pulses during the deceleration process, conical or double conical buffer mechanisms can be considered.
It is important to note that the selected buffer device should have an adequate flow capacity for the one-way valve. Insufficient flow capacity can lead to undesired effects during practical applications. For instance, if the design of the buffer device is not optimal, the hydraulic cylinder may experience sudden stops or retreats when starting from the side with the buffer device. Therefore, when designing the buffer device, it is crucial to fully consider the flow capacity of the one-way valve to avoid such issues.
When selecting a hydraulic cylinder, it is advisable to check its buffering capacity and ensure that it meets the requirements of the application. The specific buffering capacity will depend on the operational needs and the desired performance of the hydraulic system.
