What problems should be paid attention to when cleaning the oil tank of the freight elevator

As a transportation equipment for vertical lifting of goods, freight elevators are now popularized in all corners of social life and are used more and more widely. Whether in construction, civil engineering, or installation and maintenance in daily life, they are inseparable from the use of freight elevators. The hydraulic system is an important part of the elevator machinery. When the hydraulic oil enters the hydraulic system, cleanliness is the primary issue. Dirt and other impurities should be prevented from entering the system. As you already know, tiny particles can scratch the valve, jam the pump, block the orifice, and cause costly repairs. Maintaining the hydraulic system is the key to the safe use and long-term use of the freight elevator machinery. How to correctly master the maintenance method of the hydraulic system? How to keep the hydraulic system clean?
1. The freight elevator should keep the system clean
Change the oil and filter regularly. A good hydraulic oil contains a variety of additives, these additives can prevent oil deterioration or block system parts. However, these additives will lose their effectiveness after a period of time. Therefore, the oil should be changed regularly to ensure that the additives are effective. The filter can only absorb a limited number of dirt particles and other impurities from the oil. Replace the filter according to the recommended cycle to keep the system clean.

2. Keep the hydraulic oil clean in hydraulic lift freight elevators
Store the oil in a clean place, and be cautious when changing or refueling. Only use a clean funnel equipped with a fine mesh filter to pour oil from the container into the tank. Of course, the oil you use must be the type recommended by the equipment manufacturer.
3.The freight elevator should be regularly drained and refueled
It is very important to regularly discharge the water and sediment in the oil tank to remove impurities in the oil, but it is also very important to discharge the entire hydraulic system regularly. This is the only reliable way to completely remove system impurities, oxidized hydraulic oil and other harmful substances. Then, the recommended clean hydraulic oil should be refilled into the system.
If the hydraulic oil of the rail lift freight elevator has been completely contaminated, especially when the pump is damaged, the oil in the oil tank must be cleaned. The oil is allowed to flow through the oil cleaning device until the oil pollution indicator shows that the oil is in a satisfactory state.
