Abstract
The utility model provides a long cantilever axle centrifugal water pump axle sleeve under water, the axle sleeve inner wall is equipped with spiral self-lubricating water course under water, transversely sets up 2 at least pressure inlet tubes in the equidistant 2 of compound axle sleeve lower part of cast iron graphite, and pressure inlet tube one end is direct and self-lubricating water course intercommunication, and the other end is connected on high pressure water pipeline. The utility model discloses can improve self-lubricating water course internal cooling water velocity of flow, effectively improve the self-lubricating effect of axle sleeve under water, make major axis cantilever centrifugal pump axle sleeve average life cycle under water by about one year prolong to 8.5 years, greatly reduced use cost.
Description
Technical field
This utility model belongs to technical field of mechanical equipment, particularly to the underwater shaft of a kind of long cantilever axle centrifugal water pump
Set.
Background technology
At present, the major axis cantilever centrifugal water pump axle sleeve under water of domestic production all uses iron casting structure, at water
Lower shaft sleeve inwall is provided with spiral self-lubricating water channel, and axle sleeve lower end is provided with water inlet pipe, and cooling water is introduced into bottom
After cavity, then entered self-lubricating water channel by cavity.Find during use, due to design reasons, long axle suspension
All there is the problem that bearing of relying on oneself is the most wear-resisting, self-lubricating is not enough in arm centrifugal water pump axle sleeve under water, causes underwater shaft
The set use cycle is short, generally uses the time of cycle left and right the most one year.
Summary of the invention
This utility model is intended to improve the self-lubricating effect of axle sleeve under water, extends major axis cantilever centrifugal water pump under water
The service life of axle sleeve.
To this end, this utility model takes following technical solution:
A kind of long cantilever axle centrifugal water pump axle sleeve under water, sleeve lining is provided with spiral self-lubricating water channel under water,
At cast iron graphite composite shaft sleeve bottom at least 3 pressure water inlet pipes of equidistant horizontally set, pressure water inlet pipe one
End directly connects with self-lubricating water channel, and the other end is connected on device systems high-pressure water pipeline.
The beneficial effects of the utility model are:
This utility model can improve self-lubricating water channel inner cooling water flow velocity, is effectively improved the self-lubricating of axle sleeve under water
Effect, extends the service life of major axis cantilever centrifugal water pump axle sleeve under water, makes major axis cantilever centrifugal water pump under water
Axle sleeve averagely uses the cycle to be extended to 8.5 years by about 1 year, greatly reduces use cost.
Accompanying drawing explanation
Fig. 1 is underwater shaft nested structure generalized section.
In figure: main shaft 1, self-lubricating water channel 2, cast iron graphite composite shaft sleeve 3, pressure water inlet pipe 4.
Detailed description of the invention
As seen from Figure 1, this utility model one is the water will installed outside the main shaft 1 of long cantilever axle centrifugal water pump
Lower shaft sleeve is changed into cast iron graphite composite shaft sleeve 3 by former cast iron axle sleeve, and the inwall of cast iron graphite composite shaft sleeve 3 sets
There is spiral self-lubricating water channel 2.Two is to change into being arranged on cast iron stone by the former axial water inlet pipe being located at axle sleeve lower end
The side of ink composite shaft sleeve 3, i.e. in the equidistant horizontally set in bottom 3 pressure of cast iron graphite composite shaft sleeve 3
Power water inlet pipe 4, pressure water inlet pipe 4 one end directly connects with self-lubricating water channel 2, and the other end is connected to equipment system
On the high-pressure water pipeline of system, high-pressure water pipeline provide high-pressure cooling water.
