Sliding friction shoe and the swash plate is a swash plate piston friction pairs in three of the most complex pair. Lists the plunger rod ball and slipper ball gap (see Figure 2), roller hydraulic maintenance fee if the plunger slipper gap tolerance and plunger high pressure oil chamber will be from the ball plunger the escape of the shoe clearance, roller hydraulic repair shop, shoe and the swash plate film thinning, Shaanxi hydraulic maintenance, can cause severe hydrostatic bearing failure, the friction shoe and the swash plate metal contact occurs ablation shoe off, Roller hydraulic maintenance, scratched ball plunger swash plate. When the plunger rod ball and slipper ball beyond the tolerance of 1.5 times, a group must replace it. In the dynamic damper has a screw plug holes and build gas metering edge, build gas holes due to leave the air, when compressed air is compressed, the compressed air has a shock-absorbing effect, the equivalent of a miniature shock absorber. When the hole in the compressed air, oil filled, upon expansion, the hydraulic oil out, so that adds an additional liquidity in order to change the original flow. It is also possible to reduce or eliminate noise and vibration.
