Maintenance and Upkeep of Hydraulic Speed Reducers
1. After the hydraulic reducer has operated for 200 to 300 hours, the initial oil change should be performed. Subsequently, the quality of the oil should be checked regularly during use; oil that has become contaminated with impurities or has deteriorated must be replaced immediately. Generally, for hydraulic reducers operating continuously over long periods, the oil should be replaced with fresh oil every 5,000 operating hours or once per year. For reducers that have been out of service for an extended period, the oil should also be replaced with fresh oil prior to resuming operation. The reducer should be filled with oil of the same brand as originally used; mixing oils of different brands is prohibited. However, oils of the same brand but different viscosities are permitted to be mixed.
2. When changing the oil, wait until the reducer has cooled down sufficiently to eliminate any risk of burns, yet remains warm. This is because if the unit cools down completely, the oil's viscosity will increase, making it difficult to drain. Note: Be sure to cut off the power supply to the transmission device to prevent accidental energization.
3. During the operation of the hydraulic reducer, if the oil temperature rise exceeds 80°C, the oil sump temperature exceeds 100°C, or abnormal noises are detected, operation must be halted immediately. The cause of the issue must be investigated and the fault rectified; operation may only resume after the issue has been resolved and the lubricating oil has been replaced.
4. Users should establish reasonable regulations for usage and maintenance. Detailed records should be kept regarding the reducer's operational status and any issues identified during inspections. The aforementioned regulations must be strictly adhered to.
Hydraulic Reducer Maintenance and Care:
Selection of Lubricating Oil: When selecting lubricating oil based on the bearing load of a mobile hydraulic reducer, a lubricant with a lower penetration value should be chosen for heavy-load applications. When operating under high-pressure conditions, in addition to having a low penetration value, the lubricant must also possess high oil film strength.
Mixing different types of lubricating oils is strictly prohibited. The specific locations of the oil level plug, oil drain plug, and breather vent are determined by the reducer's installation orientation.
In summary, the key to effective operation of a hydraulic reducer lies in performing regular inspections and routine maintenance on the equipment. Only through such consistent care can the reducer function properly and contribute to enhanced operational efficiency.
