Description
Technical field
The present invention relates to liquid conveying technology field, particularly relate to a kind of water pump.
Background technology
Water pump is typically made up of parts such as motor, the pump housing, pump shaft and impellers, is widely used in distruting water transregionally, farmland
Irrigate, produce the fields such as water supply and sewage.
In water pump, pump shaft is as the critical piece of transmission mechanical energy, and pump shaft stretches in the pump housing by the pump cover on the pump housing,
One end of pump shaft is connected with machine shaft by shaft coupling, and the other end supports impeller and is maintained at operating position and rotates.
Add filler, mechanical seal etc. between pump shaft and pump cover and constitute sealing structure, it is ensured that the negative relative in the pump housing.Due to pump shaft
Rotary speed higher, and there is frictional force between the contact component such as mechanical seal, long-time use after, pump shaft can be formed
Certain eroded area, causes shorten service life, affects sealing property, and then affects the properly functioning of water pump.Most
The abrasion of axle class is difficult to discover, and when only occurring the situation such as machine high temperature, big, the abnormal sound of amplitude of beating, just can cause discovering of people,
But to people realize time, major part axle is the most worn-out, thus causes machine down, affects production efficiency.
When conveying has the solid-liquid two-phase flow such as Huanghe water etc. of abrasion containing silt water, the blade of water pump vane, sealing ring
Place's serious wear, thus affect the service behaviour of water pump, even causing impeller failure, water pump is shut down, and needs often to change in production,
The extra work add user's shutdown, changing affects production efficiency especially.Pump shaft supports through bearing body, pump shaft front end and impeller
Fixing connection, impeller is located in the pump housing, and bearing body is fixed through pump cover and the pump housing and is connected, in order to ensure impeller in the running, the pump housing
Interior liquid can not leak in bearing body, is generally provided with machine sealing chamber between impeller and bearing body, and machine sealing chamber is usually provided at
Pump cover center cavity, pump cover front end is provided with the sealing hole being connected with impeller, and middle part is provided with the through hole being connected with positioning sleeve, rear portion
Being provided with machine sealing chamber, pump cover periphery Circle-Array shows the fixing hole being connected with bearing body, in the through hole at pump cover center and machine sealing chamber
Pump shaft on be fixed with positioning sleeve, mechanical seal and machine sealed cover successively, pump cover front end end count seal ring is connected with impeller seals,
Rear end is tightly connected with pump cover through fastening bolt.Its deficiency is: owing to machine seal apparatus part is many, then cannot ensure each cooperation face
Precision, cause the sealing property of machine sealing chamber cavity to reduce, and the cylindrical remaining operation when mounted of machine sealing chamber cavity
Space is minimum, is often difficult to operation, assembling inconvenience when causing part exchanging, and if in use in medium containing granule
During thing, easily cause the friction of particulate matter and mechanical seal, cause the damage of mechanical seal, have a strong impact on water pump mechanical seal
Sealing, the penetration by liquid machine seal apparatus being likely to result in water pump extraction time more serious is leaked on pump shaft, affects the longevity of pump shaft
Ordering and bearing body is caused liquid corrosion, the maintenance work for whole water pump has numerous impact.
During it addition, present water pump cover is installed, the joint face of the spiral case of pump cover and water pump, pump cover and the connection of bearing block
Face is all a smooth face, needs manually to spiral case and pump cover when water pump is installed, and whether pump cover and bearing block correction center
Alignment fastens with bolt the most again, such mounting structure make installment work can not people's complete independently, and not
Can guarantee that every time can correct calibration center, it is ensured that the installation accuracy of water pump, it is ensured that the reliability of water pump operation, wastes more
Many manpowers, water pump efficiency of assembling is low, is unfavorable for industrial mass manufacture water pump.
After water pump works long hours, owing to the extract of water pump extraction can penetrate into the spiral case of water pump and the connection of pump cover
On face, of long duration joint face can be caused certain corrosion so that spiral case is bonded together with pump cover, the need when water pump is safeguarded
Spiral case to be dismantled and pump cover internal structure is checked and keeps in repair, but owing to spiral case is bonded together with pump cover, often
Compare the most difficult separating, percussion can only be used or be forcibly separating by instrument, easily water pump structure being damaged, make water pump
Precision changes, and may affect the normal use of water pump so that maintenance work is inconvenient to carry out.
