Description

Technical Field

[0001] The present application relates to the field of lubrication pumps, and in particular to a dual-medium hydraulic lubrication pump. Background Art

[0002] A lubrication pump is a lubrication device that supplies lubricant to lubrication parts.

[0003] The Chinese patent with the authorization announcement number CN209705685U discloses a lubrication pump, including an oil tank mechanism, an oil tank seat for mounting the oil tank mechanism; the oil tank seat is provided with an oil inlet and an oil outlet, the oil tank mechanism includes a packaging wall and a cavity defined by the packaging wall; one end of the packaging wall is connected to the oil tank seat; the packaging wall is provided with an exhaust pipe extending outward; the upper end of the exhaust pipe is connected with an exhaust valve assembly; the exhaust valve assembly includes an inner cavity and an exhaust port; a floating ball is matched in the gap in the inner cavity, and a piston mechanism is provided in the cavity; the piston mechanism divides the cavity into an oil storage cavity and an air cavity; the oil inlet and the oil outlet are both connected to the oil storage cavity. The beneficial effect of the utility model is that as the lubricating oil is input into the inner cavity, the floating ball floats close to the contraction port under the load of the lubricating oil, and the air is discharged from the exhaust port until the floating ball contacts the contraction port. Since the floating ball contacts the contraction port, the exhaust port is sealed, and at this time the oil storage cavity is filled with lubricating oil, and the air is also discharged from the exhaust port, thereby improving the quality of the lubricating oil output from the oil storage cavity.

[0004] With respect to the above-mentioned related technologies, the lubrication pump can only output one lubrication medium to the lubrication point. When the lubrication pump lubricates different lubrication points, different lubrication mediums need to be used because different lubrication points have different lubrication requirements. Therefore, multiple lubrication pumps are required to lubricate different lubrication points respectively, which increases operating costs. Utility Model Content
