Diesel hydraulic power unit is a kind of equipment commonly used in industrial production, which is used to achieve the motion control of mechanical equipment through the pressure transfer of hydraulic oil. However, in the process of use, some failures often occur, affecting productivity. This article will introduce common failures and their causes, and provide solutions to help practitioners solve the problem.
First, the pressure of the diesel hydraulic power unit is not stable
Pressure instability is a common failure phenomenon, mainly manifested in large pressure fluctuations or can not reach the set value. The causes of this failure may be the following:
1. oil pump failure: wear or damage to the internal seals of the oil pump, resulting in leakage, which in turn affects the pressure stability of the diesel hydraulic power unit.
Solution: Replace the internal seals of the pump to ensure good sealing performance.
2. Impurities, water, and other pollutants affect the fluid in the diesel hydraulic power unit, changing its viscosity and impacting the pressure stability of the hydraulic power unit.
Solution: Regular replacement of the fluid, and strengthen the filtration and purification of the fluid to ensure the cleanliness of the fluid.
3. Oil temperature is too high: when working, the oil temperature is too high will lead to changes in oil viscosity, which in turn affects the pressure stability of the diesel hydraulic power unit.
Solution: Increase the heat sink to reduce the working temperature of the diesel hydraulic power unit to ensure that the fluid temperature within the normal range.
Second, serious leakage of diesel hydraulic power unit
Leakage is another common failure phenomenon, mainly for the oil from the pipeline, joints and other leaks. Causes of this failure may be the following:
1. loose joints: Loose joints cause oil to leak from them.
Solution: Check the fittings to make sure they are tightened securely.
2. Aging of seals: Seals will age after a long period of time and lose their sealing properties, resulting in leakage.
Solution: Replace the seals regularly to ensure good sealing performance.
3. Wear and tear of piping: piping will wear out after a long time of use, resulting in leakage.
Solution: Regularly check the pipeline, and replace it in time when it is found to be worn.
Third, the diesel hydraulic power unit excessive noise
Excessive noise is a common failure phenomenon, mainly manifested in the work of abnormal noise. Causes of this failure may be the following:
1. oil pump failure: the internal parts of the oil pump worn or loose, resulting in increased noise.
Solution: Replace the worn or loose internal parts of the oil pump to ensure that the oil pump works properly.
2. Impurities, water, and other pollutants affect the oil, changing its viscosity and generating noise.
Solution: Regular replacement of the fluid, and strengthen the filtration and purification of the fluid to ensure the cleanliness of the fluid.
3. Worn or loose internal parts of the hydraulic cylinder result in increased noise.
Solution: Replace the worn or loose parts inside the hydraulic cylinder to ensure that the hydraulic cylinder works normally.
In summary, common failures of diesel hydraulic power units include unstable pressure, serious leakage and excessive noise. The causes of these failures may involve oil pump failure, oil contamination, high oil temperature, loose fittings, aging seals and worn piping. Solutions to these failures include replacing the internal seals of the oil pump, replacing the fluid regularly, adding heat sinks, checking and tightening fittings, and replacing seals and lines in the diesel hydraulic power unit. By taking these measures, you can effectively solve the failure problems of diesel hydraulic power units. As a result, productivity can be improved.
