What do I need to know when the Excavator is operating in winter?

As a Volvo Style Pin Wholesale, to share with you first of all, the startup method is not suitable.

In winter, the temperature is very low and the equipment cannot start up smoothly. Starting the excavator in winter, you can place insulation in the water tank, open the drain valve and continuously pour clean soft water into the water tank at 60-70 ° C. When the water flowing out of the drain valve becomes hot, close the drain valve, pour warm water into the warm water tank at 90-100 ° C, shake the crankshaft, and properly lubricate the moving parts.

Second, do not pay attention to insulation.

Do not pay attention to insulation when working in winter. This will shorten life and damage the engine. Thermal insulation is the key to using diesel engines in winter.

Thermostats play an important role in heating diesel engines during winter work. Therefore, in order to properly maintain the excavator before winter, the excavator thermostat should be checked. If a defect is found, it must be repaired or replaced.

Third, pay attention to the framework. We have Caterpillar Bucket Teeth on sale.

After work, the excavator must be idle to extinguish the flames. If the cooling water temperature is below 60 ° C, the water will not heat up and the fire will stop. Otherwise, when the temperature is high, your body will be suddenly affected by the cold air.

Fourth, low load operation.

After the excavator started, some drivers couldn't wait to get into the load. However, due to the low temperature of diesel engines, the viscosity of the engine is low and oil does not easily fill the frictional surfaces of moving pairs, which may cause severe wear of the machine.

In addition, due to insufficient warm-up of the machine, the plunger spring, valve spring and ejector spring are also vulnerable to "cold brittleness" damage.

Five, fuel.

Due to lower winter temperatures, excavator maintenance usually results in reduced diesel fluidity, increased viscosity, difficult spraying, more severe atomization and combustion, diesel power and economy.

How to place an excavator in winter?

The movement of the excavator is very complicated. All the mechanisms are often started, braked, changed direction, load changes, frequent shocks and vibrations, as well as field work, changes in temperature and astronomical position, plus the cold weather in winter. The operating characteristics and environmental characteristics of the hydraulic system of the machine should be:

(1) High transmission efficiency, giving full play to engine power and fuel economy.

(2) The hydraulic system and hydraulic components have sufficient reliability under the influence of large load changes and severe vibration and shock.

(3) Adjust the heavy-duty and anti-vibration coolers to reduce the total heat generated by the system, so that the temperature of the hydraulic oil does not exceed 80 degrees, or the temperature rise does not exceed 45 degrees Celsius during continuous operation of the host.

(4) Due to the dust on the excavator construction site, the hydraulic oil is easily polluted, the hydraulic system has better sealing performance, and the hydraulic components are not sensitive to oil pollution. The entire hydraulic system is equipped with an oil filter and dust-proof installation.

(5) The hydraulic or electro-hydraulic servo device is used to make the excavator equipped with an automatic control system to improve the technical performance of the excavator and reduce the labor intensity of the driver.
