As the transportation equipment for the vertical lifting of goods, the lift freight elevator has now been popularized in every corner of social life, and is used more and more widely. Whether it is construction, civil engineering, or installation and maintenance in daily life, the use of freight elevators is inseparable.

The hydraulic system is an important part of the freight elevator machinery. When the hydraulic oil enters the hydraulic system for operation, cleaning is the primary issue. Dirt and other impurities should be prevented from entering the system. As you already know, tiny particles can scratch valves, jam pumps, and block orifices, resulting in costly repairs.

Maintaining the hydraulic system is the key to the safe use and long-term use of the elevator machine. How to correctly master the maintenance method of the hydraulic system? How to keep the hydraulic system clean?






First ,the hydraulic elevator should keep the hydraulic oil clean
Store oil in a clean place, and be careful when changing oil or refueling. The oil can only be poured from the container into the tank using a clean funnel equipped with a fine mesh filter. Of course, the oil you use must be the type recommended by the device manufacturer.

Second, the elevator should keep the system clean
Change oil and filter regularly. Good hydraulic oil contains a variety of additives that prevent oil deterioration or block system parts. However, these additives will be ineffective over time. The oil should be replaced periodically to ensure that the additives are used. Filters can only absorb a limited amount of dirt and other impurities from oil. Replace the filter with recommended cycles to keep the system clean.

Third, the ladder should be oil and refuel regularly
Regularly releasing water and sediment in the tank is important for removing impurities in the oil, but it is also important to regularly empty the entire hydraulic system. This is the only reliable way to completely remove the impurities of the system, the hydraulic oil and other Harmful substances that are oxidized. The recommended clean hydraulic oil should then be added to the system.

If the hydraulic oil of the guide elevator is completely polluted, especially when the pump is damaged, the oil in the tank must be cleaned. The oil is flowing through the oil cleaning device until the oil pollution indicator shows that the oil is in satisfactory condition .
