Abstract
The utility model relates to the technical field of a stainless steel punching pump, in particular to a stainless steel punching pump zero leakage sealing structure, which comprises a pump body middle section, an impeller and a sealing ring. The stainless steel punching pump zero leakage sealing structure is characterized in that the stainless steel punching pump zero leakage sealing structure is provided with a sealing ring press cover, the sealing ring press cover is formed by surrounding an upper press cover and a sealing ring arranged on the periphery of the upper press cover, the center of the upper press cover is provided with an impeller hub through hole, the sealing ring is pressed on the upper end of an inner hole of the pump body middle section through the upper press cover arranged at the upper end of the sealing ring press cover, the outer periphery of the sealing ring press cover is connected with the outer wall of the inner hole of the pump body middle section through the sealing ring in a sealed way, and an impeller hub passes through the sealing ring press cover and the sealing ring arranged in the sealing ring press cover to be connected with the inner hole of the pump body middle section in a sealed way. The stainless steel punching pump zero leakage sealing structure has the advantages that the structure is simple, the sealing performance is high, the leakage is avoided, the operation is stable, the service life is long, and the like.
Description
Technical field
The utility model relates to stainless steel stamping pump technical field, specifically a kind of stainless steel stamping pump non-leakage sealing structure.
Background technique
At present, the impeller of existing stainless steel stamping pump is inserted in the endoporus in pump housing stage casing by wheel hub conventionally, impeller hub and pump housing stage casing endoporus are again through seal ring seal, the deficiency of this structure is: owing to using seal ring seal can only guarantee axial seal, and sealing surface is very narrow, cause leakage rate large, fluctuation of service, working life is short.
Summary of the invention
The purpose of this utility model is to solve above-mentioned the deficiencies in the prior art, provide a kind of simple in structure, sealability is high, without leaking, the stainless steel stamping pump non-leakage sealing structure of stable, long service life.
The utility model solves the technological scheme that its technical problem adopts:
A kind of stainless steel stamping pump non-leakage sealing structure, comprise pump housing stage casing, impeller and seal ring, it is characterized in that being provided with seal ring gland, described seal ring gland is to be crowded around and formed by the seal ring of upper press cover and upper press cover periphery, described upper press cover center is provided with impeller hub perforation, described seal ring gland adopts teflon to make, to reach the effect of sealability height and anti-aging endurance, described seal ring is pressed in the endoporus upper end in pump housing stage casing through the upper press cover of seal ring gland upper end, seal ring gland periphery is tightly connected through the endoporus outer wall in seal ring and pump housing stage casing, impeller hub is tightly connected through seal ring and pump housing stage casing endoporus in seal ring gland and seal ring gland, by the axial and radial seal to pump shaft, greatly widened sealing surface, thereby realized the object of zero leakage.
The utility model is owing to adopting said structure, have simple in structure, sealability is high, without leaking, the advantage such as stable, long service life.
accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Reference character: pump housing stage casing 1, impeller 2, seal ring 3, seal ring gland 4, upper press cover 5, seal ring 6.
Embodiment:
Below in conjunction with accompanying drawing, the utility model is further illustrated:
As shown in drawings, a kind of stainless steel stamping pump non-leakage sealing structure, comprise pump housing stage casing 1, impeller 2 and seal ring 3, it is characterized in that being provided with seal ring gland 4, described seal ring gland 4 is to be crowded around and formed by the seal ring 6 of upper press cover 5 and upper press cover 5 peripheries, described upper press cover 5 centers are provided with impeller hub perforation, described seal ring gland 4 adopts teflon to make, to reach the effect of sealability height and anti-aging endurance, described seal ring 3 is pressed in the endoporus upper end in pump housing stage casing through the upper press cover 5 of seal ring gland 4 upper ends, seal ring gland 4 peripheries are interlocked and are tightly connected with the endoporus outer wall in pump housing stage casing 1 through seal ring 6, impeller 2 wheel hubs press the seal ring 3 in 4 lids and seal ring gland 4 to be tightly connected with pump housing stage casing endoporus 1 through seal ring, by the axial and radial seal to pump shaft, greatly widened sealing surface, thereby realized the object of zero leakage.
The utility model is in when operation, by seal ring gland and seal ring, to axially and radially the sealing of pump shaft, greatly widened sealing surface, thereby realized the object of zero leakage.
The utility model is owing to adopting said structure, have simple in structure, sealability is high, without leaking, the advantage such as stable, long service life.
