Disadvantages of hydraulic tools

① Easy to leak. The hydraulic system has a high oil pressure, and hydraulic oil is prone to leakage through seals or gaps, causing hydraulic medium consumption and environmental pollution Low transmission efficiency: Hydraulic transmission often experiences significant energy losses (such as pressure loss and flow loss) during the energy transmission process, resulting in low transmission efficiency. ③ Inaccurate transmission ratio. Due to factors such as the compressibility of the transmission medium, leakage, and pipeline elastic deformation, hydraulic systems cannot strictly guarantee fixed ratio transmission. ④ The viscosity of temperature sensitive oil varies with temperature, causing changes in flow rate, leakage rate, and resistance, which can easily cause unstable movement of the working mechanism. ⑤ High manufacturing costs require high manufacturing accuracy for hydraulic components in order to reduce leakage, thereby increasing manufacturing costs.
