Information

When the hot dog days come, construction machinery and equipment will be more prone to hidden dangers. Therefore, summer maintenance and maintenance are of great significance to the safe use of construction machinery in high-temperature environments and to extend the service life of the whole machine.

The following points are possible failures and emergency solutions for construction machinery in high temperature environments, and how to do a good job in the daily maintenance of construction machinery in summer.

Faults that are prone to occur at high temperatures:

1. Hydraulic system failure

In the high temperature environment, the hydraulic system will often experience failures such as pipe burst, joint leakage, solenoid valve coil burnt, hydraulic valve jam, and loud noise; the system using accumulators may cause damage to the accumulator due to the high temperature of the hydraulic oil; The aging circuit in summer will be more likely to cause the outer skin to crack due to the thermal expansion and contraction of the metal, causing short-circuit failure; the electrical components in the control cabinet are also prone to failure in the high-temperature season, and key control components such as industrial computers and PLCs may also crash and operate. Failures such as slow speed and control failure.

2. Engine failure

Under high temperature conditions, it is easy to cause the engine to "boil", reduce the viscosity of the oil, and cause failures such as cylinder pulling and tile burning. At the same time, the output power of the engine is reduced.

Equipment operation and maintenance measures

1. Do a good job in the early maintenance of construction machinery

Entering the dog days, it is best to do a comprehensive maintenance of the construction machinery, and focus on the maintenance of the equipment and components that are prone to high temperature failure; replace the three filters and oil, replace or adjust the tape, and check the fan, water pump, and power generation. Whether the performance of the engine and compressor is reliable, and if necessary, perform maintenance, repair or replacement.

Properly increase the viscosity level of the engine oil, and check whether the cooling system and fuel system are unblocked; replace the aging wires, plugs, and hoses; check and tighten the fuel pipeline to prevent fuel leakage; clean up the oil and dust on the engine body to ensure the engine "Pack lightly", good heat dissipation.

2. In summer construction, the key maintenance and maintenance methods

1) The engine oil and lubricating oil in various places need to be replaced with summer oil, and the amount of oil is appropriate; always check whether there is oil leakage, especially the fuel, which should be refilled in time.

2) The equipment should be parked in a cool place as much as possible to avoid sun exposure.

3) Pay attention to the damage of rain and dust to the equipment. It is best to replace all kinds of filter elements regularly. The hydraulic system radiator should be cleaned regularly so that it can maintain a good heat dissipation effect. Avoid long-term overload work. If the brakes are overheated, it is strictly forbidden to use water to cool down.

The maintenance of construction machinery and equipment, especially the maintenance under the high temperature environment in summer, should follow the principles of timely, reasonable and comprehensive in order to improve the performance of the equipment and adapt to the high temperature and working conditions of the outside world. Track and manage equipment, keep abreast of equipment performance dynamics, and formulate specific measures for different equipment during specific operations.

The above are some of the measures taken by the editor to prevent heatstroke in construction machinery during the dog days. If you don't understand anything, you can contact us Shenzhen Weishibo Machinery Equipment Co., Ltd. We will serve you wholeheartedly.
