Description

Technical Field

[0001] The utility model relates to the technical field of lubrication pumps, in particular to the field of heat dissipation of dry oil lubrication pumps. Background Art

[0002] Dry oil lubrication pumps often use semi-solid plastic lubricants in the lubrication process of mechanical equipment. Compared with ordinary grease lubrication pumps, they require a higher oil outlet pressure and the heat dissipated by the pump body is also higher.

[0003] The existing dry oil lubrication pump has a low heat dissipation coefficient. During the use of the dry oil lubrication pump, its own temperature is often too high, which affects the operating efficiency and reduces the life of parts.

[0025] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0026] In the drawings, the same reference numerals all refer to the same components.

[0027] like Figure 1-5As shown, the utility model provides a dry oil lubrication pump that utilizes liquid circulation to dissipate heat, comprising a pump body 1 and an oil outlet 1 arranged on the pump body 1, a radiator device is installed on the pump body 1, and the radiator device comprises: a heat sink 3, which is installed on the outer surface of the pump body 1; a liquid pipeline 4, which is wound around the oil outlet 1 and the pump body 1 and is partially fixed and closely connected to the back side of the heat sink 3; a fan 5, which is fixed on the front side of the heat sink 3; a water pump 6, which is fixed on the pump body 1 and connected to the liquid pipeline 4.

[0028] Furthermore, the heat sink 3 is in the shape of a thin plate, and may also be in the shape of a fin-shaped heat sink 9 .

[0029] Furthermore, the liquid in the liquid pipeline 4 is deionized pure water 7 .

[0030] Furthermore, the portion of the liquid pipeline 4 fixed to the back of the heat sink 3 is zigzag, thereby increasing the contact area between the heat sink 3 and the liquid pipeline 4 .

[0031] Furthermore, a water pump 6 is installed on the liquid pipe 4 between the heat sink 3 and the oil outlet 1 to control the direction of water flow so that the water flows in from the direction close to the heat sink 3, and then flows toward the oil outlet 1 through the pressurized push of the water pump 6.

[0032] Furthermore, the heat sink 3 is made of metal, and may preferably be made of copper.

[0033] Furthermore, the liquid pipeline 4 is made of copper and is fixed to the pump body 1 by means of a buckle 8 .

[0034] The first embodiment of the utility model is as follows:

[0035] When the dry oil lubrication pump of the present technical solution is working, the heat dissipation device is turned on, and the water pump 6 pushes the deionized pure water 7 in the liquid pipeline 4. The deionized pure water 7 passes through the pump body 1 and the oil outlet 1, and brings the heat to the heat sink 3. The heat on the heat sink 3 is reduced by the fan 5 through the air flow. The deionized pure water 7 cooled by the heat sink 3 is again pressurized and transported to the oil outlet 1 and the liquid pipeline 4 on the pump body 1 through the water pump 6, thereby achieving the purpose of liquid circulation and heat dissipation;

[0036] The second embodiment of the utility model is as follows:

[0037] When the dry oil lubrication pump has several oil outlets 2, the required pressure increases and the heat increases accordingly. The liquid pipeline 4 is wrapped around each oil outlet 2, and the heat sink 3 is replaced with a fin-shaped heat sink 9. When the dry oil lubrication pump starts working, the heat of the pump body 1 and each oil outlet 2 is also conducted to the fin-shaped heat sink 9 along the liquid pipeline 4 and dissipated to the outside.
