Mechanical equipment failures that are prone to occur in summer

1) Hydraulic system malfunction
In high temperature environments, hydraulic systems often experience malfunctions such as pipe bursting, joint oil leakage, solenoid valve coil burnout, hydraulic valve jamming, and loud noise. For systems using accumulators, the accumulator may be damaged due to the high temperature of the hydraulic oil; In summer, aging circuits are more prone to cracking of the outer skin due to the thermal expansion and contraction of metals, resulting in short circuit faults; The electrical components inside the control cabinet are also prone to malfunction during high temperature seasons, and key control components such as industrial computers may also crash and run slowly. Control failures and other malfunctions.

2) Lubrication system malfunction
Long term operation of construction machinery at high temperatures can lead to poor performance of lubrication systems, deterioration of engine oil, wear and tear of transmission systems such as chassis, as well as affecting exterior paint coatings, braking systems, clutches, throttle control systems, and metal structures.  .

3) Engine malfunction
The impact of high temperature on the engine is mainly manifested in the rapid temperature rise of the engine, while the high external temperature may cause the engine to "boil", thereby reducing the viscosity of the oil and causing mechanical failures such as cylinder pulling and tile burning. At the same time, it reduces the sustained high temperature of the engine and has strict requirements for the air permeability of the radiator. This requires the cooling system to continue to operate at high loads, reducing the service life of components such as fans and water pumps, especially those commonly used in air conditioning compressors and fans. This can easily lead to its failure.

4) Other faults
Summer has high temperatures and humidity. If the exhaust hole of the battery is blocked, it may cause an explosion due to the increase in internal pressure; When working in high temperature environments during summer, tires not only experience increased wear and tear, but also burst due to the rise in internal air pressure; In summer, the transmission belt will become longer, which can cause the transmission to slip and accelerate wear. Failure to adjust in a timely manner can lead to belt breakage and other malfunctions. Small cracks on the driver's cabin glass may expand or even burst due to large temperature differences between the inside and outside or water splashing in summer.
