After just 1.5 years of operation, the crankshaft on a high-pressure three-plunger pump suddenly failed. What are the potential reasons for this unexpected failure?
Take a look at the attached image showing the other end of the experience. We welcome anyone who would like to share their own experience and provide feedback on this topic. Let's start a discussion!
Could fatigue be caused by the presence of striation marks on the fracture surface? Explore the relationship between fatigue and the visible marks left on a broken surface.
No visible marks can be seen on the surface. See the 30X magnified image of the fillet area below for a closer look.

I fully support Josh's observation that the issue appears to be fatigue failure, possibly stemming from an initial injury at a specific point. It is possible that capillary cracks may have formed as a result.
The unexpected failure of the crankshaft on your high-pressure three-plunger pump could be due to a variety of factors. Poor lubrication, extreme operation conditions, or manufacturing defects could have contributed. Also, consider load fluctuations and misalignment; these can exert excessive pressure or cause uneven wear and tear. It may be useful to conduct a thorough examination of the pump and its operating conditions to pinpoint the exact cause and prevent such incidents in the future.
This failure could potentially be linked to multiple factors. The quality of the crankshaft's material, inadequate lubrication, and operating conditions such as contaminated fluid or excessive load can all play significant roles. Faulty installation or improper alignment during the operation process can also lead to premature wear and sudden failures. As well as, an absence of regular maintenance can also compromise the part's life cycle. It would be ideal to conduct a thorough investigation to narrow down the exact cause.
There could be a number of potential reasons. It's possible that the pump was operating beyond its designed limit either on pressure or flow rate, resulting in excessive strain on the crankshaft. Alternatively, it could be due to insufficient or incorrect maintenance - are the bearings being greased regularly and properly? Material defect in the crankshaft could also be responsible. But it's also important to examine whether it experienced any severe vibrational loading or transient shock during its runtime, as that could lead to premature failure.
It's surprising to hear about the crankshaft failure after such a short period, and there could be several factors at play here. Perhaps there was an issue with misalignment during installation, which can lead to uneven stress on the components. It’s also possible that the lubrication was inadequate or contaminated, causing excessive wear. Additionally, if the pump was operating beyond its rated capacity or if there were irregular pressure spikes, those could easily contribute to premature failure. A thorough inspection of operation conditions and maintenance records might reveal more clues about what went wrong.
It’s definitely concerning to see a crankshaft failure in such a short time frame! Possible reasons could include inadequate lubrication, manufacturing defects, or misalignment during installation that led to excessive stress. Additionally, operating the pump outside its specified parameters, like pressure or temperature, might have contributed to premature wear. It might be worth looking into the maintenance history and ensuring that all components were fitted correctly to identify any weaknesses or oversight in the setup.
It’s surprising to hear about the crankshaft failure after such a short span; it could stem from several reasons like improper lubrication, misalignment, or even the material quality not being up to par. Additionally, if the pump was subjected to excessive loads or operating outside its designed parameters, that could also contribute to premature wear. It's crucial to review maintenance records, operational conditions, and any signs of wear that might indicate underlying issues.

Answer: Answer: The crankshaft failure could be due to various factors such as material defects, improper lubrication, excessive stress or load, misalignment, or inadequate maintenance practices.
Answer: Answer: Material defects in the crankshaft, such as impurities during manufacturing or poor quality materials, can compromise the structural integrity and load-bearing capacity of the component, making it more prone to failure under high-pressure conditions.
Answer: Answer: Improper lubrication can lead to increased friction and wear on the crankshaft bearings, causing accelerated deterioration and potential failure over time. Inadequate lubrication can also result in overheating and increased stress on the crankshaft.
Answer: Answer: Excessive stress or load on the crankshaft, beyond its design limits, can lead to fatigue, cracks, and ultimately failure. This could be caused by operating the pump beyond its rated capacity or encountering unexpected spikes in pressure or temperature.
