Check the cylinder for any signs of internal leaks, such as fluid seepage or worn seals. Replace any faulty components and ensure proper sealing to prevent drift. Undersized cylinders: If the master cylinder is undersized for the required lifting capacity, excessive drift may result. Make sure the cylinder bore and stroke length are appropriate for the load being lifted. pollute: Contaminated hydraulic fluid: Contaminants in the hydraulic fluid, such as dirt, debris or moisture, can affect the performance of the master cylinder. Regularly check and change hydraulic fluid to prevent contamination and maintain peak performance. Filtration system problems: Check and clean or replace the hydraulic oil filtration system to ensure it is effectively removing contaminants from the fluid. Clogged or malfunctioning filters can lead to increased levels of contamination. Improper load distribution: Uneven load distribution: Uneven weight distribution of the lift mechanism can cause the master cylinder to operate inefficiently or unevenly. Make sure the load is evenly distributed over the lifting points and adjust the lifting mechanism if necessary to achieve proper balance. External factor: Environmental Conditions: Extreme temperature, humidity or exposure to corrosive substances can affect hydraulic system performance. Take necessary measures to protect the system from adverse environmental conditions, such as providing insulation, ventilation or protective coating.
