(1) according to different load requirements, often check, adjust the relief valve pressure, so that just right.
(2) a reasonable choice of hydraulic oil, especially oil viscosity, in conditions permitting, try to use a little lower viscosity to reduce the viscosity of friction loss.
(3) to improve the lubrication of sports parts to reduce the friction loss, is conducive to reducing the workload and reduce heat.
(4) to improve the hydraulic components and hydraulic system assembly quality and their own accuracy, and strictly control the fit with the gap and improve the lubrication conditions. The use of small friction coefficient of sealing material and improve the sealing structure, as far as possible to reduce the hydraulic cylinder of the starting force to reduce the mechanical friction generated by the heat.
(5) If necessary, add a cooling device.
