introduction：The pressure oil passes through the throttle into each oil chamber of the guide rail，Float moving parts，The guide rail surface is separated by oil film，The oil in the oil chamber continually flows back to the tank through the sealing edge。When the moving guide rail is subjected to external load and produces a downward displacement，Smaller rail clearance，Increased oil return resistance，Increase the oil pressure in the oil chamber，To balance the external load。 Closed guide：Aboard...、Oil cavities are opened on the lower guide surface，Can withstand two-way external loads，Ensure smooth operation of moving parts。 According to the oil supply, it can be divided into quantitative static pressure guide and constant pressure static pressure guide。 Constant pressure hydrostatic guide rail： Refers to the oil pressure at the inlet of the throttlepsBe certain，This is the most widely used static guide rail。 Quantitative static guide：
