Technical field
This utility model relates to centrifugal pump bearing gland, particularly to a kind of centrifugal pump by oil-proof bearing pressure
Lid.
Background technology
The bearing of centrifugal pump needs lubrication, and general high speed pump uses oil lubrication, and the most so-called thin oil moistens
Sliding；Slow-speed of revolution pump uses grease lubrication, the most so-called dry oil lubrication.
When using thin oil lubricant, lubricating oil is through bearing, the perturbation action of locking nut, although oil indoor oil
Face is less than axis hole, also can spill from axis hole；Finally result in grease chamber's oil level in a short time to reduce, insufficient lubrication,
Bearing failure damages, and causes economic loss.
Similar prior art is typically:
Shown in Figure 1, non-explosion environment, felt collar 1 or outside framework oil seal can be used, it is also possible to accomplish not let out
Leakage；But contact between felt collar, outside framework oil seal and axis body, quick abrasion, need often to change, extremely inconvenient.
Shown in Figure 2, in explosive environment, it is necessary to use non-contacting labyrinth seal；Labyrinth seal by
In being not in contact with friction, spark will not be produced, do not have explosion danger；The bearing gland of general petrochemical industry pump
2, it is necessary to use maze trough 3 to seal；The wall do not processed is detained a large amount of lubricating oil, when entering maze trough
When oil mass is more than oil-recovery tank 4 return flow, lubricating oil will be from the gap 6 between maze trough and dust pan 5
Outwards spill.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of simple in construction, can reduce entrance maze trough
Lubricants capacity, stop the oil-proof bearing gland of a kind of centrifugal pump of Leakage.
For reaching above-mentioned purpose, the technical solution of the utility model is as follows:
A kind of oil-proof bearing gland of centrifugal pump, described bearing gland is arranged on bearing housing by bolt,
Described bearing gland is the bowl structure that middle part offers axis hole, and the axle of centrifugal pump passes this axis hole, bearing pressure
Lid includes:
One is positioned at outermost and is parallel to the installation end of axial line, and described installation end is along the circumferential direction evenly equipped with spiral shell
Keyhole；
One along the installation end inner circle periphery oil return wall extended to axis hole direction, and described oil return wall is table
The oil return wall that face is smooth；
One to axis hole direction and is parallel to the sealed end that axial line is extended along oil return wall inner circle periphery；
The medial surface of described sealed end is provided with the first oil-recovery tank being along the circumferential direction distributed；
Described sealed end is positioned at the face of cylinder of axis hole and is provided with maze trough；
The medial surface of described sealed end is provided with the second oil-recovery tank of depth penetration maze trough.
In an embodiment of the present utility model, the angle between described oil return wall and installation end is 45
Degree.
In an embodiment of the present utility model, described maze trough is made up of 2 to 3 cannelures.
In an embodiment of the present utility model, described first oil-recovery tank is cannelure.
In an embodiment of the present utility model, described second oil-recovery tank is U-lag, and its width is more than
6mm。
By technique scheme, the beneficial effects of the utility model are:
The setting of this utility model the first oil-recovery tank prevents major part lubricating oil to enter maze trough, thus reduces
Flow into flow, arranged by the setting and U-shaped structure strengthening the second oil-recovery tank width, prevent lubricating oil from returning
Stream is obstructed, and then reduces leakage；Furthermore improve lubricating oil flow speed by smooth oil return wall, reduce
It is detained, reduces the flow flowing into maze trough, and then reduce leakage probability.

Detailed description of the invention
For the technological means making this utility model realize, creation characteristic, reach purpose and be readily apparent from effect
Understand, below in conjunction with being specifically illustrating, this utility model is expanded on further.
See shown in Fig. 3 to Fig. 5, the utility model discloses a kind of oil-proof bearing gland 10 of centrifugal pump,
Bearing gland 10 is arranged on pump case by bolt 20, and bearing gland 10 offers axis hole 11 for middle part
Bowl structure, the axis body of centrifugal pump passes this axis hole, and bearing gland 10 includes that one is positioned at outermost and parallel
In the installation end 12 of axial line, described installation end 12 is along the circumferential direction evenly equipped with bolt hole 13, during installation,
Bearing gland 10 is fixed on bearing housing by bolt 20 through bolt hole 13；
Bearing gland 10 also includes one along the installation end inner circle periphery oil return wall extended to axis hole direction
14, oil return wall 14 is ganoid oil return wall；It can reduce lubricating oil and be detained at oil return wall,
Thus reduce lubricating oil and flow into flow；Angle between oil return wall 14 and installation end 12 is 45 degree, should
Angle arranges and can reduce lubricating oil inflow flow further.
Bearing gland 10 also includes that one to axis hole direction along oil return wall inner circle periphery and is parallel to axial line and prolongs
Stretch the sealed end 15 of setting；The medial surface stating sealed end 15 is provided with the first oil return being along the circumferential direction distributed
Groove 16, the first oil-recovery tank is cannelure, and it can effectively stop lubricating oil on oil return wall to enter maze trough,
Reduce lubricating oil and flow into flow；Sealed end 15 is positioned at the face of cylinder of axis hole and is provided with maze trough 17, maze trough
17 are made up of 2 to 3 cannelures, and lubricating oil can be stoped to leak out；On the medial surface of sealed end 15
Being provided with the second oil-recovery tank 18 of depth penetration maze trough, the second oil-recovery tank is U-lag, and its width is more than 6mm,
Second oil-recovery tank can destroy surface tension of liquid, reduces flow resistance, increases conveyance capacity.
When the centrifugal pump is operated, centrifugal pump is due to bearing, the centrifugal disturbance of locking nut, and lubricating oil splashes axle
On the oil return wall 14 of pressure cap 10, lubricating oil flows down along smooth oil return wall 14 action of gravity, portion
Divide and enter the first oil-recovery tank 16, flow down along the first oil-recovery tank 16, avoid bearing gland endoporus；A small amount of lubrication
Oil enters maze trough 17, along maze trough 17 downwards, is pooled to the second oil-recovery tank 18, finally flows back to grease chamber.
