Concrete pump trucks play a crucial role in infrastructure construction, particularly in industries such as construction and engineering. To ensure safe and normal operation, it is essential to avoid overheating in the hydraulic system, as it can cause significant damage. The following are the main effects of overheating:
- Seal Deterioration:
- When the hydraulic system overheats, the seals within the system may deteriorate due to high temperatures. This can cause the seals to lose their elasticity, reducing their sealing ability. In severe cases, the seals may fail entirely, increasing the risk of fluid leakage.
- Reduced Lubrication:
- Overheating reduces the viscosity of the hydraulic fluid, which in turn decreases its lubricating properties. This can lead to increased wear on hydraulic components, significantly shortening their lifespan.
- Decreased Pump Efficiency:
- As the temperature of the hydraulic fluid rises and its viscosity decreases, the pump may experience increased internal leakage. This results in a reduction in the pump’s actual flow rate, impacting its overall efficiency.
- Valve Malfunction:
- Different materials in the hydraulic valves, such as the valve core and valve body, may expand at different rates when exposed to heat. This can cause the valve core to become stuck, preventing the concrete pump from operating normally.
To avoid these issues, it is important to regularly cool down the pump truck during operation. Different causes of overheating require specific measures to address them, ensuring the longevity of the pump truck. Proper maintenance and attention to overheating can help prevent costly breakdowns and extend the machine’s life.
