Description
Technical field
This utility model relates to a kind of vertical pump and seals structure, belongs to pump field of sealing technology.
Background technology
Sealing is a part indispensable on pump, ensures that medium will not leak, protects site environment, also avoids simultaneously
The harm that people caused due to dielectric leakages such as poisonous and harmfuls.Traditional vertical pump uses and seals usually packing seal knot
Structure, as it is shown in figure 1, this structure loads filler in stuffing box, is compressed by gland, to ensure the decrement of filler, from
And reach the purpose sealed.Packing seal structure is complicated, and installation difficulty is big, and packing seal effect is poor, and leakage rate is relatively
Greatly, do not ensure that good sealing effectiveness especially for toxic and harmful, thus scene is caused some potential safety hazards.
Further, since filler abrasion is very fast, needs often to change, add maintenance cost, waste time and energy.
Utility model content
The purpose of this utility model is to solve the packing seal structure that traditional vertical pump uses, and seals gas medium
Weak effect, and need the problems such as frequent replacing, and provide a kind of vertical pump to seal structure.
The purpose of this utility model is achieved through the following technical solutions:
A kind of vertical pump of the present utility model seals structure, including support, seals lower cover, sealing upper cover, Seal Oil；
Sealing lower cover is the annular element that internal diameter is more than pump shaft external diameter, and the anchor ring upper surface sealing lower cover is machined with U-lag,
Sealing upper cover is the annular element that internal diameter matches with pump shaft external diameter, and the anchor ring lower surface sealing upper cover is machined with U-shaped
Groove,
Seal upper cover to be fixed on pump shaft, seal lower cover and be fixed on outside pump shaft by support, make sealing upper cover U-lag
Outer is downwardly in the U-lag sealing lower cover, and the interior edge sealing lower cover U-lag is inserted upwardly in the U-lag sealing upper cover, and
Seal between the outer of upper cover U-lag and the U-lag sealing lower cover, seal the interior edge of lower cover U-lag and the U-lag sealing upper cover
Between leave running clearance；In the U-lag sealing lower cover, it is filled with Seal Oil, and the liquid level of Seal Oil is higher than in sealing
The outer of lid U-lag is away from the height sealing lower cover U-lag bottom surface.
By mutual lap seal lower cover and sealing upper cover between pump shaft and support, form labyrinth seal, and close in labyrinth
Inject Seal Oil in the gap of envelope, make to be sealed by Seal Oil isolation between pump shaft and support, prevent the poisonous and harmful gas of lower section
Body is revealed.
Beneficial effect:
Vertical pump of the present utility model seals, simple in construction, easy accessibility, to gas medium good sealing effect, seals
Material is without changing, and there is not wear problem, and service life is long.
Accompanying drawing explanation
Fig. 1 is traditional vertical pump packing seal structure schematic diagram；
Fig. 2 is the structural representation that this utility model vertical pump seals；
In figure, 1-support；2-seals lower cover；3-seals upper cover；4-pump shaft；5-Seal Oil.
Detailed description of the invention
With embodiment, content of the present utility model is further described below in conjunction with the accompanying drawings
Embodiment
A kind of vertical pump of the present utility model seals structure, as it is shown in figure 1, include support 1, seal in lower cover 2, sealing
Lid 3, Seal Oil 5；
Sealing lower cover 2 and be more than the annular element of pump shaft external diameter for internal diameter, the anchor ring upper surface sealing lower cover 2 is machined with U-lag,
Sealing upper cover 3 is the annular element that internal diameter matches with pump shaft external diameter, and the anchor ring lower surface sealing upper cover 3 is machined with U
Shape groove,
Seal upper cover 3 to be fixed on pump shaft 4, seal lower cover 2 and be fixed on outside pump shaft 4 by support 1, make sealing upper cover 3U
The outer of shape groove is downwardly in the U-lag sealing lower cover 2, and the interior edge sealing lower cover 2U shape groove is inserted upwardly into the U sealing upper cover 3
In shape groove, and seal between the outer of upper cover 3U shape groove and the U-lag sealing lower cover 2, seal the interior edge of lower cover 2U shape groove with close
Seal up and leave running clearance between the U-lag of lid 3；It is filled with Seal Oil 5 in the U-lag sealing lower cover 2, and Seal Oil 5
Liquid level is higher than sealing the outer of upper cover 3U shape groove away from the height sealing lower cover 2U shape groove bottom.
By mutual lap seal lower cover 2 and sealing upper cover 3 between pump shaft 4 and support 1, form labyrinth seal, and fan
Inject Seal Oil in the gap that palace seals, make to be sealed by Seal Oil isolation between pump shaft 4 and support 1, prevent the poisonous of lower section
Harmful gas is revealed.
