Proper selection of hydraulic oil serves as the core premise to maintain the stable operation of electric forklift hydraulic systems, which directly affects the service life of core components including the lifting cylinder, tilting valve and steering power unit.
First, users need to match the hydraulic oil type according to the actual working ambient temperature. For scenarios with low temperature in high-altitude or northern cold regions, you are recommended to choose hydraulic oil with low solidification point, which can avoid excessive flow resistance caused by poor fluidity at low temperature. For high-temperature and heavy-load working conditions, hydraulic oil with high viscosity index is more suitable, which can maintain stable lubricating performance even under long-time high-load operation, and avoid accelerated wear of sealing elements caused by too thin oil film.
Second, you need to strictly refer to the recommended viscosity grade in the electric forklift operation manual, and never mix different types of hydraulic oil without professional guidance. Random mixing may lead to physical and chemical property changes of the oil, block the filter screen inside the hydraulic pipeline, and cause common faults such as stuck reversing valve and slow lifting response.
Third, pay attention to the anti-wear and anti-oxidation performance index of the selected hydraulic oil. Qualified hydraulic oil can reduce the abrasion of the inner wall of the oil cylinder and the plunger pump, effectively prolong the oil change cycle, and reduce the long-term operation and maintenance cost of the equipment.
