Failures that are prone to occur in mechanical equipment in summer

1) Failure of the hydraulic system

In the high temperature environment, the hydraulic system will often experience faults such as pipe burst, oil leakage from joints, solenoid valve coil burnt, hydraulic valve stuck, and loud noise. For systems using accumulators, the accumulator may be damaged due to the high temperature of the hydraulic oil; In summer, the aging circuit will be more likely to cause the outer skin to crack due to the thermal expansion and contraction of the metal, resulting in short-circuit failure; the electrical components in the control cabinet are also prone to failure in high temperature seasons, and key control components such as industrial computers may also crash and run slowly. , control failure and other faults.

2) Failure of the lubrication system

Long-term operation of construction machinery at high temperature will lead to poor performance of the lubrication system, easy deterioration of oil, easy wear and tear of the chassis and other transmission systems, and will also affect the exterior paint layer, braking system, clutch, throttle control system and metal structure. .

3) Engine failure

The impact of high temperature on the engine is mainly manifested in the rapid temperature rise of the engine, and the high external temperature is likely to cause the engine to "boil", which will reduce the viscosity of the oil, resulting in mechanical failures such as cylinder pulling and tile burning, and at the same time reducing the engine The continuous high temperature has strict requirements on the permeability of the radiator, which requires the continuous high-load operation of the cooling system, which reduces the life of the cooling system fan, water pump and other components, and is particularly frequently used for air-conditioning compressors and fans. , which can easily lead to its failure.

4) Other faults

In summer, the temperature is high and the humidity is high. If the air vent of the battery is blocked, it will cause an explosion due to the increase of internal pressure; when the tire works in a high temperature environment in summer, not only the wear of the tire will be aggravated, but also the tire will burst due to the increase of the internal air pressure; The transmission belt will become longer in summer, which will cause the transmission to slip and accelerate wear and tear. Failure to adjust it in time will lead to failures such as belt breakage. Small cracks in the cab glass will expand or even burst due to the large temperature difference between inside and outside or splashing water in summer.
