During the operation of hydraulic lift freight elevators, excessively high oil temperatures can cause the equipment to malfunction. The main symptoms include a reduced lifting capacity that fails to meet design specifications and a slower response time with decreased lifting speed. This not only affects productivity but also poses safety risks if left unaddressed. Jinan Ruihai Hydraulic Machinery Co., Ltd. is a leading domestic manufacturer specializing in the production of hydraulic lifts, lifting platforms, and aluminum alloy lifts. As a member of the China Lifting and Transportation Warehousing and Logistics Association, the company is known for its commitment to quality, reliability, and customer satisfaction. So, what causes the hydraulic oil temperature to rise in freight elevators? According to Jinan Ruihai, there are several key factors: 1. **Internal Cylinder Issues**: After prolonged use, the internal damping oil seal may wear out significantly, leading to increased internal leakage and higher operating temperatures. *Solution*: Replace the worn-out oil seals with corrosion-resistant alternatives to improve efficiency and reduce heat buildup. 2. **Hydraulic System Design Flaws**: The system includes a power unit, cylinder, and high-pressure oil pipes. If the tubing has a small inner diameter or becomes bent due to external forces (such as wind or sun exposure), it can restrict oil flow, increasing pressure and causing the oil temperature to rise. *Solution*: Install high-quality hydraulic hoses with appropriate dimensions to ensure smooth oil flow and reduce pressure-related overheating. 3. **Motor Maintenance Neglect**: Poor maintenance of the motor that powers the elevator can lead to bearing damage. A worn rotor may cause friction, generating excessive heat and affecting overall performance. *Solution*: Regularly maintain the motor and apply high-temperature, wear-resistant lithium grease to the bearings for extended service life. 4. **Faulty Joystick Operation**: Wear, rust, or inflexible rotation of the joystick can prevent the hydraulic system from unloading properly, resulting in continuous pressure and elevated oil temperatures. *Solution*: Apply wear-resistant, high-temperature lithium-based grease to all moving parts of the joystick to ensure smooth operation and timely system unloading. 5. **Damaged Filters**: If the oil filter mesh or suction pipe filter is damaged, foreign particles and impurities can enter the system, clogging the oil circuit and increasing resistance, which leads to overheating. *Solution*: Use a fine mesh oil filter to prevent contamination and ensure clean, uninterrupted oil flow. By addressing these common issues, users can significantly extend the lifespan of their hydraulic lift systems and ensure safe, efficient operation.
