Four tips to make your excavator work efficiently in the hot summer!

[BONOVO]

"Winter to see 39, summer to see three Fu", just sent away the cold winter, has entered the scorching summer. The alternations of large temperature differences are also a test for excavators. In addition to the normal maintenance of original parts, we also need to pay attention to the following points to ensure that our equipment can safely spend the hot summer:

First, check whether the antifreeze expires and needs to be replaced

Antifreeze should be used all year round, not just in winter. Antifreeze has two characteristics: low freezing point and high boiling point. It can not only ensure the normal operation of the vehicle cooling system in the winter, but also prevent the cooling water from boiling in the summer to avoid the situation of "boiling pot".

In addition, antifreeze has the effect of anti-rust and anti-corrosion. Because in the cooling system, there are metal materials and non-metal materials. The anti-rust and anti-corrosion effects of antifreeze can slow down the aging of the entire cooling system.

In addition, antifreeze has the function of preventing scale. It can reduce the scale in the cooling system clogging the circulation pipe and other hidden dangers affecting the engine. The engine is the "heart" of the equipment, and the antifreeze cooling for the "heart" is particularly important. The authentic antifreeze of the mainstream brand can be used for more than 2000 hours, and the general antifreeze can only be used for about 1000 hours. Different brands of antifreeze contain different additives and can not be mixed.

Second, the selection of grease (butter) should be appropriate

The temperature in summer is high, the working temperature of the excavator is higher, and the temperature has a great impact on the fluidity of the grease. As the temperature rises, the grease becomes softer, which reduces the adhesion performance of the grease and makes it easy to lose, resulting in a decline in the lubrication performance of the working device and the rotating device.

In addition, under the condition of higher temperature, it is easy to increase the evaporation loss of grease, and the phenomenon of oxidation deterioration and condensation oil separation is serious. Therefore, to choose a good grease, never choose a grease that looks like flour.

The extreme pressure lithium base grease has excellent water resistance, mechanical stability, extreme pressure and wear resistance, water and pumping resistance, rust resistance and oxidation stability. Under extremely harsh operating conditions, it can provide the best lubrication and sealing effect for the equipment to meet the needs of different working conditions of the equipment.

Third, check whether the water tank, hydraulic oil radiator and air conditioning condenser are blocked

After the autumn, winter, and spring excavator, these places are easy to accumulate some withered grass and rotten leaves, catkins and other adsorbent. These things hinder the cooling effect of water tanks, hydraulic oil radiators and air conditioning condensers. It is easy to cause engine high temperature, hydraulic oil high temperature deterioration, air conditioning refrigeration effect is not good.

In addition, the cover plate and sponge at the water tank and radiator of some excavatorare damaged or fallen off, resulting in abnormal fan suction, resulting in poor heat dissipation of the water tank, hydraulic oil radiator and air conditioning condenser.

In order to ensure the normal use of the excavator, it is necessary to always pay attention to the number of boxes of the water temperature meter, and take immediate measures when it reaches a certain level. You can choose to stop in the nearby shade and idle to cool down, and pay attention to not immediately turn off the engine to prevent accidents such as cylinder pulling caused by overheating inside the engine. After the temperature drops, in addition to checking whether the antifreeze is lacking, the tension and fatigue of the fan belt should also be checked.

Fourth, wading operation, do not let the water exceed the center of the heavy wheel



Summer is a rainy season, if your equipment is working in water, then you should pay attention to the following aspects: if the water overflows the rotary gear ring, pay attention to timely replacement of the grease in the gear ring, (if the sand is mixed in the grease, it is easy to aggravate the wear of the gear and the gear ring).

When working in water, do not tilt the excavatormore than 15 degrees (to avoid the upper structure being immersed in water and damaging the radiator fan); The track tensioning cylinder should also be loosened frequently (there is a lot of rain in summer, to remove the mud on the cylinder and prevent the cylinder from rusting).

Conclusion:

After the end of the day's work, the excavatorshould run for a few minutes on a small throttle, and then turn off the engine after the standby temperature drops. If the excavation is parked for a long time due to irresistible factors such as weather, the fuel tank should be filled with diesel to avoid rust. When parking, remove the battery, place the battery in a dry and moisture-proof place, and keep the surface clean and dry. When cleaning the excavator, do not sprinkle water directly on the electrical components, otherwise it will lead to failure or failure of the electrical components.

In addition to the above points, special attention should be paid to vehicle circuit problems in the summer. Due to the high temperature working environment in summer, it will aggravate the aging of equipment lines. Regularly check whether the line cracks and molts to avoid unnecessary faults, so as not to affect the progress of the project.
