Description
Technical field
This utility model is related to water pump member arts, more particularly to a kind of wear-resisting pump shaft and the water pump using the pump shaft.
Background technology
Water pump is typically made up of the part such as motor, the pump housing, pump shaft and impeller, is widely used in distruting water transregionally, farmland
Irrigate, produce the fields such as water supply and sewage.In water pump, critical piece of the pump shaft as transmission mechanical energy, pump shaft is by the pump housing
Pump cover is stretched in the pump housing, and one end of pump shaft is connected with machine shaft by shaft coupling, and the other end supports impeller and is maintained at work
Position rotates.Filler, mechanical seal etc. are added between pump shaft and pump cover and constitutes sealing structure, it is ensured that the phase in the pump housing
To negative pressure.As the rotary speed of pump shaft is higher, there is frictional force between the contact component such as mechanical seal, use for a long time
Afterwards, certain eroded area can be formed with pump shaft, causes service life to shorten, be affected sealing property, and then affect water pump
It is normal to run.The abrasion of most axle class is difficult to discover, and only occurs that machine high temperature, bounce amplitude be big, when abnormal sound,
Can cause discovering for people, but to people realize when, most of axle is all worn-out, so as to cause machine down, affects production
Efficiency.
Some special industries are particularly objectively in the urgent need to excellent resistance to of the water pump that anticorrosive anti-wear has concurrently, especially wearability
Rotten type water pump, and water pump industry technology personnel are by a variety of effort, the anticorrosive anti-wear of water pump has been made it is various it is different attempt, but by

Because wearability or rotproofness by force and frequently do not change pump shaft during industry water pump use so that using enterprise operation cost liter
Height, production efficiency be not high, and the long-term objective reality of this phenomenon fails to be changed.Although technical staff knows that such water pump market is huge
Greatly, water pump application industry and manufacturing are all wanted to solve, and a kind of cost price of exploitation is low, and comprehensive cost performance is good, and rotproofness is wear-resisting
The good Pump Axle of property.In current science highly developed today, although foregoing problems seem simple, but really fail to realize it is low into
This breakthrough.Aforementioned is exactly the objective present situation of anticorrosive anti-wear Pump Axle.
In water pump, pump shaft is connected with motor by means of shaft coupling, by motor as the critical piece of transmission mechanical energy
Torque pass to impeller, its effect is self-evident, centrifugal pump abrasion be unavoidable problem, centrifugation pump work when, due to pump
Friction is there is between axle and centrifugal pump inner stuffing, centrifugal pump leakage is easily caused, be this not only lowers the use longevity of pump shaft
Life, there is also certain potential safety hazard.Based on this, a kind of new pump shaft of centrifugal pump or necessary is designed.
