Causes of Valmet 55 Hydraulic System Failures
Valmet 55 is a renowned piece of heavy machinery used in various industries for its robust performance and reliable hydraulic system. However, like any hydraulic system, the Valmet 55 can experience failures due to numerous factors. This article aims to explore the common causes of hydraulic system failures in Valmet 55 machines.
1. Contamination:
One of the leading causes of hydraulic system failures in Valmet 55 is contamination within the system. Contaminants such as dirt, debris, dust, or water can enter the hydraulic fluid, causing damage to crucial components like valves, pumps, and cylinders. Contamination can occur during maintenance, through poor filtration, or external factors.
2. Fluid Overheating:
Excessive heat in the hydraulic system can lead to various failures. Overheating can occur due to long operating hours, inadequate cooling systems, excessive loads, or incorrect fluid viscosity. Persistent high temperatures can degrade the fluid, leading to reduced lubrication properties and increased wear on system components.
3. Fluid Degradation:
Over time, hydraulic fluid can degrade due to oxidation, moisture absorption, and thermal stress. This degradation can result in reduced viscosity, loss of lubrication properties, increased sludge formation, and compromised overall system performance. Regular fluid analysis and maintenance can help mitigate this cause of system failures.
4. Component Wear and Tear:
Hydraulic system failures can also occur due to wear and tear of various components. Prolonged usage, high-pressure conditions, inadequate lubrication, or poor maintenance practices can lead to the deterioration of seals, pump internals, valves, and other critical parts. Regular inspection and preventive maintenance can significantly reduce this factor.
5. Improper Maintenance and Servicing:
Failure to follow proper maintenance procedures, intervals, and using incorrect fluids can greatly contribute to hydraulic system failures. Lax maintenance practices, neglected servicing, or lack of awareness about recommended guidelines can result in system malfunctions, reduced efficiency, and increased risk of component failures.
6. Inadequate Filtration:
Filtration plays a crucial role in maintaining optimal hydraulic system performance. Inadequate filtration or using filters beyond their recommended service life can allow contaminants to enter the system, leading to accelerated wear, reduced fluid quality, and increased failure risks. Regular filter replacement and adhering to manufacturer recommendations can ensure proper filtration.
Conclusion:
While the Valmet 55 hydraulic system is known for its reliability, several factors can contribute to failures. Contamination, fluid overheating, fluid degradation, component wear and tear, improper maintenance, and inadequate filtration are some of the common causes. To ensure the longevity and efficient operation of the Valmet 55 hydraulic system, it is crucial to implement a comprehensive maintenance plan that addresses these potential issues.
