Description

Structure for preventing contamination of grease pump

The present invention relates to a pollution prevention structure of a grease pump, and more particularly, by applying a contamination prevention packing material to an insert plate of a grease pump, when the grease is sucked from the grease container, grease can be easily prevented from leaking. It relates to the anti-pollution structure of one grease pump.

Typically, a grease pump is a mechanism that automatically pumps grease from a grease container in which grease is stored.

In the main configuration of the grease pump, as shown in FIG. 1 to FIG. 2, the pump body 10, the driving cylinder 12 for raising and lowering the pump body 10, and the pump body 10. The insert plate 14 attached to the lower end of the head), an air bleeding hose, a grease suction hose, and the like connected to the insert plate 14 are formed.

The insert plate 14 has a disc shape, and a packing material 20b as shown in Fig. 5 is attached to the peripheral surface thereof.

Therefore, after positioning the grease cylinder under the insert plate, the drive cylinder is driven to lower the insert plate together with the pump body.

At this time, the insert plate is inserted into the inner diameter surface of the grease barrel, and the packing bound to the circumferential surface of the insert plate is in close contact with the inner surface of the grease barrel.

Accordingly, the grease is discharged to the outside through the grease suction hose by the driving of the pump, in which the grease escapes into the gap between the packing of the insert plate and the inner diameter surface of the grease barrel.

When the grease comes out, the surrounding area is considerably contaminated, and the waste of grease causes a serious problem.

In addition, a gap between the packing of the insert plate and the inner surface of the grease container penetrates a contaminant such as dust, thereby causing contamination of the grease.

Therefore, the present invention has been made in order to solve the above disadvantages, by changing the packing of the insert plate of the grease pump to a dual structure, it is possible to easily prevent grease leakage and to improve the clean environment of the workplace. The purpose is to provide an antifouling structure of a grease pump.

The present invention for achieving this object is to attach a packing material having a double rubber packing to the circumferential surface of the insert plate of the grease pump, to prevent grease leakage from the gap with the inner diameter surface of the grease container. A pollution prevention structure of a grease pump is provided.

In a preferred embodiment, the packing material is characterized by consisting of a circular annular MC nylon, a rubber packing integrally mounted on the upper and lower surfaces of the MC nylon, and an SS41 iron plate integrally fastened to the upper rubber packing.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is a front view to which the pollution prevention structure according to the present invention is applied, and FIG. 2 is a side view.

As described above, the grease pump includes a pump body 10 providing a substantial pumping force, a drive cylinder 12 engaged with the pump body 10 to move the pump body 10 up and down, and the pump body 10. And an insert plate 14 mounted on the lower end of the &lt; RTI ID = 0.0 &gt;), &lt; / RTI &gt;

Here, the packing material 20a of the present invention is fastened to the circumferential surface of the insert plate 14, and the packing material 20a having the rubber packing 22 of the double structure is integrally attached to each other so that the grease container ( The main feature is to prevent grease leakage from the gap with the inner diameter surface of 16).

Preferably, the packing material 20a is a circular annular MC nylon 24, a rubber packing 22 integrally mounted on the upper and lower surfaces of the MC nylon 24, and the upper rubber packing integrally. SS41 iron plate 26 is fastened to each other, the size of each size is as follows.

The rubber packing 22 is φ 292 × inner diameter 202 × thickness 5, and the SS41 iron plate 26 is φ 260 × inner diameter 203 × thickness 8, and the MC nylon 24 has φ 252 × inner diameter. (195) x thickness (40).

Therefore, after positioning the grease container 16 under the insert plate 14, the driving cylinder 12 is driven to lower the insert plate 14 together with the pump body 10. The plate 14 is inserted into the inner diameter surface of the grease cylinder 16, and the packing material 20a, which is bound to the circumferential surface of the insert plate 14, is in close contact with the inner diameter surface of the grease cylinder 16.

That is, the double rubber packing 22 of the packing material 20a comes into close contact with the inner diameter surface of the grease container 16.

Accordingly, the grease is discharged to the outside through the grease suction hose by the driving of the pump, wherein the grease leakage from the grease container 16 is not made by the double rubber packing force of the insert plate 14. Therefore, it is possible to easily solve the problems caused by the existing grease leakage.

As described above, according to the pollution prevention structure of the grease pump according to the present invention, by applying a rubber packing of the double structure to the peripheral surface of the insert plate of the grease pump, grease does not leak at all from the grease barrel, It is possible to prevent contamination around the work site due to grease leakage and to prevent waste of grease.
