The oil station is usually installed in the underground oil depot or pit near the machine for easy maintenance and operation. During the working process, the lubricating oil is first sucked out of the oil tank by the gear pump, then passes through the one-way valve, double-cylinder mesh filter and columnar oil cooler for treatment, and finally is directly delivered to the lubricating parts of the equipment, ensuring that the relative motion parts can be fully lubricated, and at the same time, the wear metal particles generated during the movement are also removed.
