Description

Sealing structure of fluid delivery pump

Technical Field

The utility model relates to a fluid delivery pump technical field especially relates to a seal structure of fluid delivery pump.

Background

At present, the technology of a fluid delivery pump has leakage defects, 1. after the equipment is used for 3 months, the fault phenomenon of a large amount of leaked ink occurs, so that a large amount of environmental pollution and cost waste are caused; 2. when the pump body is extruded, the work is done only by pulling back the axis of the reciprocating cylinder, that is, when the cylinder reciprocates, the fluid is extruded and does work only in one motion direction, and the fluid extruding function can not be realized while the reciprocation is realized.

Disclosure of Invention

An object of the present invention is to provide a sealing structure of a fluid transfer pump for solving the above-mentioned problems.

The utility model discloses a following technical scheme realizes above-mentioned purpose:

the utility model provides a seal structure of fluid delivery pump, includes high-pressure stifled dish, high-pressure collecting pipe, high-pressure one-way pole and one-way end cap, be provided with first recess, second recess and third recess on one side inner wall of high-pressure stifled dish, be provided with first sealing washer in the first recess, be provided with the second sealing washer in second recess and the third recess respectively, be provided with the fourth recess on a side of high-pressure collecting pipe, be provided with non-standard sealing washer in the fourth recess, be provided with the fifth recess on the high-pressure one-way pole, be provided with the sixth recess on the inner wall of one-way end cap, be provided with in fifth recess and the sixth recess first sealing washer.

The utility model discloses it is preferred, the degree of depth of first recess is greater than the degree of depth of second recess and third recess.

The utility model discloses it is preferred, the arc shape is personally submitted in the sealing contact of nonstandard sealing washer, reduces because of sealed extrusion causes the phenomenon that the sealing washer ftractures.

The utility model discloses preferred, first sealing washer is high-pressure wear-resisting type guide ring, steps down to the internal high-pressure fluid seal nature of fluid delivery pump, and reuse rotation direction formula UN sealing washer is close to unnecessary fluid.

The utility model discloses preferred, the second sealing washer is high pressure wear-resisting type guide ring.

The beneficial effects of the utility model reside in that:

compared with the advantages of the existing known products, the sealing structure of the fluid delivery pump provided by the utility model has the advantages that the ink loss is reduced, the replacement and maintenance frequency is reduced, the fluid function can be extruded by the reciprocating motion of the cylinder, the compressed air is completely utilized, the energy consumption is reduced, and the environment is protected; the utility model has the advantages of simple structure, stable performance and longer service life.

Detailed Description

The present invention will be further explained with reference to the accompanying drawings:

as shown in fig. 1-6: the utility model provides a seal structure of fluid delivery pump, including high-pressure stifled dish 1, high-pressure collecting pipe 5, high-pressure one-way pole 8 and one-way end cap 11, be provided with first recess 2 on one side inner wall of high-pressure stifled dish 1, second recess 3 and third recess 4, first recess 2 is provided with first sealing washer 7, be provided with the second sealing washer in second recess 3 and the third recess 4 respectively, be provided with fourth recess 6 on a side of high-pressure collecting pipe 5, be provided with non-standard sealing washer 13 in the fourth recess 6, be provided with fifth recess 9 on the high-pressure one-way pole 8, be provided with sixth recess 12 on the inner wall of one-way end cap 11, be provided with first sealing washer 7 in fifth recess 9 and the sixth recess 12.

As shown in fig. 1, the depth of the first groove 2 is greater than the depth of the second groove 3 and the third groove 4.

As shown in fig. 4, the sealing contact surface of the nonstandard sealing ring 13 is arc-shaped, so that the phenomenon of cracking of the sealing ring caused by sealing extrusion is reduced.

As shown in fig. 4, the first seal ring 7 is a rotary guide type UN seal ring, and reduces the pressure of the high-pressure fluid in the fluid transfer pump body.

As shown in fig. 1, the second seal ring is a high pressure wear resistant guide ring.

To sum up, compared with the advantages of the existing known products, the sealing structure of the fluid delivery pump provided by the utility model reduces the ink loss, reduces the replacement and maintenance frequency, can extrude the fluid function by the reciprocating motion of the cylinder, completely utilizes the compressed air, reduces the energy consumption and protects the environment; the utility model has the advantages of simple structure, stable performance and longer service life.

The present invention can be implemented by various modifications without departing from the spirit and spirit of the present invention, and the above description is only a preferred and feasible embodiment of the present invention, and is not intended to limit the scope of the present invention, and all the equivalent structural changes made by using the contents of the present invention and the accompanying drawings are included in the scope of the present invention.
