Why do hydraulic
jack hydraulic cylinders set a buffer device? What is the cushioning principle? Here, the following analysis is analyzed:
In order to prevent the piston of the hydraulic
cylinder from striketing with the cylinder head, causing noise, impact, so setting a buffer device. Hydraulic cylinders are typically provided, in particular a hydraulic cylinder that is high, high speed or high.
The working principle of the buffer device is to block a partial oil between the piston and the cylinder head when the piston or cylinder is moving toward the stroke terminal, forcing him from the small hole or fine seam to produce a lot of resistance, so that The working parts receive brakes, gradually slow down motion, reaching the purpose of avoiding the piston and cylinder heads.
