Description
Technical field
The utility model belongs to liquid pump apparatus manufacturing technology field, and in particular to a kind of centrifugal pump cover.
Background technique
Centrifugal pump is to be rotated using impeller and make water that centrifugal movement occur come work, and water pump is before activation, it is necessary to make to pump
It is full of water in shell and suction hose, then starts motor, pump shaft impeller and water is made to do high speed rotary motion, centrifugation fortune occurs for water
It is dynamic, it is thrown toward impeller outer edge, the runner through volute pump case flows into the pressure pipe road of water pump.
The essential structure of centrifugal pump is made of six parts, is impeller, the pump housing, pump shaft, bearing, sealing ring respectively and is filled out
Expect letter, existing centrifugal pump cover and external connection dynamics are small, while bearing is easy to happen axial movement, causes to wear, from
And influence the service life of pump cover.
Summary of the invention
The utility model is intended to provide a kind of centrifugal pump cover, close with external connection, while limiting the axial direction of bearing
Small, long service life is worn in movement.
According to the technical solution of the utility model, the centrifugal pump cover, including lid is equipped with axis at the center of lid
Hole, the outer wall and lid of axis hole form pump cover, and the axis hole is in the cone cell shunk from inside to outside；The edge of the lid is equipped with fixed
Position hole is simultaneously evenly equipped with a circle pump cover installation through-hole, and the outer end face of lid is equipped with a circle pump housing mounting hole；The outer end face of lid close to
It is equipped with annular groove at axis hole outer wall, is equipped with gusset in annular groove；The outer end of the axis hole is equipped with sealing ring, axis hole outer wall
End face is equipped with sealing cover mounting hole, and the end of axis hole outer wall is equipped with the lubrication fluid passage communicated with axis hole.
Further, the lubrication fluid passage is obliquely installed.
Further, the cone angle of the axis hole is 5-7 °.
Further, the sealing cover mounting hole is round hole, is distributed in the end face of axis hole outer wall.
Further, the outer wall of the annular groove is ladder-like.
The utility model has the beneficial effects that: axis hole is in the cone cell shunk from inside to outside, the axial fortune of bearing is limited
It is dynamic, wear small, long service life；Pump cover installation through-hole, pump housing mounting hole and sealing cover mounting hole be it is multiple, external connection is tight
Close, structural reliability is high；Lubrication fluid passage is obliquely installed, and more conducively lubricating fluid passes in and out；Equipped with annular groove and gusset, do not influencing
Reduce while intensity with material, to save cost.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Fig. 2 is the face the A-A cross-sectional view of Fig. 1.
Description of symbols: 1- lid, 2- sealing cover mounting hole, 3- pump cover installation through-hole, 4- pump housing mounting hole, 5- axis
Hole, 6- sealing ring, 7- gusset, 8- lubricate fluid passage, 9- location hole.
Specific embodiment
The utility model is described in further detail with attached drawing combined with specific embodiments below.
It is as shown in the figure: centrifugal pump cover, including lid 1, at the center of lid 1 be equipped with axis hole 5, the outer wall of axis hole 5 with
Lid 1 is that overall structure, that is, pump cover is whole.Wherein, axis hole 5 is in the cone cell shunk from inside to outside.The edge of lid 1 is equipped with positioning
Hole 9 is simultaneously evenly equipped with a circle pump cover installation through-hole 3, and pump cover installation through-hole 3 is 16 in illustrated embodiment, and location hole 9 is uniformly distributed
Two threaded holes, the outer end face of lid 1 are equipped with a circle pump housing mounting hole 4.The outer end face of lid 1 is close to being equipped at 5 outer wall of axis hole
Annular groove, gusset 7 is equipped in annular groove to be reduced while not influencing intensity with material, to save cost.Axis hole 5
Outer end be equipped with sealing ring 6, the end face of 5 outer wall of axis hole is equipped with sealing cover mounting hole 2, and the end of 5 outer wall of axis hole is equipped with and axis hole 5
The lubrication fluid passage 8 communicated.
Specifically, lubrication fluid passage 8 is obliquely installed, more conducively lubricating fluid is passed in and out.The cone angle of axis hole 5 is 5-7 °, in a reality
Applying is 6 ° in example, and spindle operation is smooth while providing limit.Sealing cover mounting hole 2 is round hole, is distributed in 5 outer wall of axis hole
End face is different from existing plum blossom shape, enhances dynamics of pump cover when external connection, while guaranteeing that spindle operation is smooth.Ring
The outer wall of connected in star be it is ladder-like, avoid excessive in the hand of groove outer wall bottom, cause to be broken, ensure that structural strength.
