  The construction of DTH bit in summer weather not only has to withstand long-term continuous operation but also withstand the impact of a high-temperature environment. Let's introduce what are the impacts.

  1. The high-temperature weather not only affects the working environment and physical and mental health of the actual operators, but also damages the diesel engines, refrigeration systems, hydraulic transmission systems, power circuits, and tires of mechanical equipment.

  2. In the high-temperature environment, the hydraulic transmission system will often have common failures such as pipe bursts, oil leakage in the connector, damage to the solenoid valve coil, jammed hydraulic solenoid valve, and loud noise; the system using accumulators because the temperature of the hydraulic oil is very high. It may cause damage to the accumulator; in the summer, the embrittlement of the power circuit will be more likely to cause the skin to crack due to the thermal expansion and contraction of the metal material, leading to common failures of short-circuit faults; the electrical components in the control box are also very easy to appear at high temperatures. Common malfunctions.

  3. Diesel engines are prone to the airlock, which makes it impossible to provide oil; the high temperature will reduce the characteristics of the intake system of diesel engines, reduce airtightness, and increase fuel consumption due to engine oil leakage.

  4. Long-term operation of construction machinery and equipment under high temperature will cause the characteristics of the air intake system to decline, the oil is easy to mold, and the automobile chassis and other transmission devices are easy to damage. In addition, the external paint film, brake system, clutch, and accelerator pedal will be automatically controlled The system and its metal components cause hazards.
