Description

Technical Field

[0002] Hydraulic oil is a lubricating oil with high viscosity and anti-corrosion properties, and is widely used in the hydraulic transmission systems of mechanical equipment; hydraulic oil can play roles in transmitting power, reducing friction, cooling and sealing, and plays a crucial role in the normal operation of mechanical equipment, with functions such as energy transmission, anti-wear, system lubrication, anti-corrosion, rust prevention, and cooling. After the production of hydraulic oil is completed, it needs to be stored with the assistance of oil drums. If the storage time is too long or there is too much contact with the outside, impurities will be generated in the drum, and filling it into the internal parts of the mechanical equipment will have a certain impact on the operation of the parts; to ensure the sealing performance, the barrel cover is tightly attached inside the barrel, and the disassembly and installation are very troublesome and laborious; after a part of the hydraulic oil in the barrel is used, the oil level in the barrel drops.

[0045] The specific usage and function of this embodiment are as follows: After the oil storage tank 101 is filled with oil, the capping mechanism 2 needs to be installed above the oil storage tank 101. During installation, the positioning plate 205 is aligned with the card slot 102 and inserted to position the capping mechanism 2. The bottom plate 201 is inserted into the oil storage tank 101, and the control rod A2042 is directly rotated. The control rod A2042 rotates and drives the driving frame 2043 to slide. The driving frame 2043 controls the pressing plate 206 to slide downward. The pressing plate 206 squeezes the rubber ring 203, and the rubber ring 203 is pushed outward.

When pumping oil, the storage cylinder 1 01 enters the oil pump through the filter tube 302, which can filter the impurities in the oil; after the oil is extracted, the oil level drops, and there is a certain distance between the lifting plate 402 and the oil level.

The thread on the surface of the threaded rotating rod 401 controls the lifting plate 402 to move downward.

The lifting plate 402 can push the hydraulic oil out of the interior of the filter assembly 3 to complete the oil pumping.
