Precautions for summer construction in the hottest

Construction machinery industry summer construction precautions

it's time to eat popsicles, drink cold drinks, and blow air conditioning. For most people, summer is still very happy. But for those of us in the construction machinery industry, summer is a tough time. It is not only a test for employees, but also a test for machines. Today, I will talk about the matters needing attention in the unification of tension range, experimental journey and basic configuration for your reference

in summer construction, it is necessary to do a good job in the maintenance of construction machinery

in summer construction, the high temperature environment will bring many difficulties to the use of construction machinery. For example, when the constant radius sample is used, the diesel engine, the "heart" component of the whole machine, will reduce the viscosity of the lubricating oil, the lubrication, and the power due to the increase of temperature, and its internal parts are also prone to wear

construction machinery in summer construction, not only to withstand the test of long-term continuous operation, but also to withstand the impact of high temperature environment. These effects are mainly reflected in the following aspects:

summer high temperature not only affects the working environment and physical health of operators, but also affects the engine Cooling system, hydraulic system, circuit and tire have certain hazards

in high temperature environment, the hydraulic system will often have pipe explosion, joint oil leakage, solenoid valve coil burning, hydraulic valve sticking, high noise and other faults; For the system using accumulator, the accumulator may be damaged due to the high temperature of hydraulic oil; In summer, aging circuits are more likely to cause skin cracking due to thermal expansion and cold contraction of metals, resulting in short-circuit faults; The electrical components in the control cabinet are also prone to failure in high temperature seasons

in summer, the temperature is high and the humidity is high. If the vent hole of the battery is blocked, it will explode due to the increase of internal pressure; Working in high temperature environment in summer, not only the wear of tire will be aggravated, but also the tire burst will be caused by the increase of internal pressure; The transmission belt will grow longer in summer, which will lead to transmission slip and accelerated wear. Failure to adjust in time will lead to belt breakage and other faults. The small cracks in the cab glass will expand or even burst in summer due to the large temperature difference between the inside and outside or splashing water

the fuel system of the engine is prone to produce air resistance, resulting in failure to supply oil; High temperature will make the performance of the intake system of incomplete engines decline, and the sealing performance will decline. The engine will leak oil and increase fuel consumption. In addition, high temperature is easy to cause deformation of parts

long time operation of construction machinery under high temperature will lead to poor performance of lubrication system, easy deterioration of oil, easy wear of chassis and other transmission systems, and will also affect the appearance paint layer, braking system, clutch, throttle control system and metal structure
