Analysis of the characteristics of the hydraulic resistance rowing machine

The biggest feature of the hydraulic resistance rowing machine is that it is highly similar to the real rowing action and cheap, so many people have taken aim at this seemingly cheap machine; but many people are worried about its durability.

The resistance of the hydraulic resistance rowing machine mainly comes from the "hydraulic buffer". In addition, no other complicated components are needed, and the overall reliability does not have much problem. The most problematic "hydraulic buffer" is somewhat similar to the syringe used for injection in terms of working principle. When the hydraulic buffer contracts, the internal piston will push the oil in the main storage cylinder to the auxiliary storage cylinder; when the hydraulic buffer When the device is stretched, the piston will suck the oil in the auxiliary oil storage cylinder into the main oil storage cylinder. Since the passage between the main and auxiliary oil storage cylinders is relatively narrow, the flow of oil is slow, resulting in resistance.

Compared with several other types of rowing machines, the piston in the hydraulic buffer must fit closely with the cylinder wall of the internal oil storage cylinder, and the friction force is also relatively large, otherwise there will be oil leakage problems. Although the resistance system of the water resistance and wind resistance rowing machine also has friction problems, it obviously does not have too much pressure; the resistance system of the magnetic control resistance rowing machine does not even have physical friction during exercise.
