In summer, it is best to do a comprehensive maintenance on the construction machinery, replace the engine with three filters and oil, replace or adjust the tape, check the performance of fans, pumps, generators, and compressors, and if necessary, perform maintenance and repairs. Or replace it. For machinery working in high temperature areas, properly increase the viscosity level of the oil, check whether the cooling system and fuel system are smooth, and replace the aged wires, plugs, hoses, check and fasten the fuel pipeline to prevent fuel leakage; clean up the engine body Oil, dust, to ensure that the engine "lightly mounted" and good heat dissipation.

2 Into the summer, special inspection and maintenance of machinery and equipment

In addition to the circuit, air conditioning system, and other equipment maintenance can be self inspection, maintenance, of course, for special equipment, warranty period of equipment, should be carried out by equipment manufacturers or professionals to avoid unnecessary losses and disputes. In the summer, maintenance of the equipment does not require a complete inspection and maintenance. The content and procedures of the inspection and maintenance work can be reasonably determined according to the use of the equipment and the maintenance of the equipment. However, the maintenance of the equipment after entering the summer must be emphasized. There is luck.

3In the summer construction process, several aspects of maintenance and maintenance should be emphasized

1) The engine oil and all parts of the lubricating oil need to be replaced with the summer oil. The amount of oil is appropriate. Regularly check whether there is any oil leakage, especially fuel, and add it in time.

2) The battery fluid needs to be replenished in time, the charging current is properly reduced, the circuit joints are required to be firm and reliable, and the aging circuit needs to be replaced. The fuse capacity should meet the requirements for safe use. Equipment should be equipped with a fire extinguisher.

3) Keep equipment in a cool place as much as possible to avoid sunlight exposure. Properly reduce the tire pressure, explosion-proof tires.

4) Pay attention to the damage caused by rain and dust on the equipment. It is advisable to replace the filter regularly. The hydraulic system radiator should be regularly cleaned to maintain good heat dissipation. Avoid overloading for a long time and control the rest time. Do not overheat the brakes, etc. Do not cool it with water.

5) Check the equipment steel structure, transmission box, axle components are flexible, whether there are small cracks, prevent high temperature damage caused by the summer increase, found that rust should be timely rust, repair, paint, so as not to rain more in summer, leading to increased corrosion .

The summer maintenance of the equipment should follow the principles of timely and reasonable, all aspects, in order to facilitate equipment operation and adapt to the outside temperature and working conditions. Need to track and manage the equipment, grasp the performance of the equipment, and develop a combination of targeted and versatile maintenance plans. In addition to the above mentioned requirements and maintenance precautions, different precautions must be taken for different mechanical equipment.
