In the cold and cold winter, the excavators in many areas are still in the working state. In this season, a little improper operation of the excavator will result in the failure. Then how can you make your excavator safe to winter and what are the misunderstandings in the winter excavator?
1. select unsuitable diesel and oil
In winter, it is too random to choose diesel, oil and hydraulic oil for the excavator. This is a big mistake in the operation. The use of unreasonable oil will affect the life of the excavator. In winter, it should choose light diesel with low condensation point and good ignition performance. The oil should also choose low condensation point, the machine oil filter is replaced, and the replacement can adapt to local winter. The lowest temperature of the hydraulic oil.
2. prematurely let off the cooling water
When to cool water in winter? First, it must be known that premature or non cooling water is a wrong operation. If no water is discharged, the residual cooling water will freeze and expand; if the engine is cooled earlier, the engine is too high at this time, suddenly the cold air will shrink suddenly, and the crack occurs seriously; the correct operation is engine. Flameout idling for a while, until the cooling water temperature reaches below 60 C, then flameout.
3. cold start engine is not ready
It is one of the wrong operations to directly start the excavator engine in cold weather. It is one of the wrong operations. It should first check whether the lock control lever is locked, the fuel control knob is transferred to the low speed position; the starting switch key is kept in the preheating position; after the engine is started, if the oil pressure monitor indicates the light is on, You can't operate the walking pedal and the joystick.
4. ignition with open fire
In particular, it is not possible to use a light fire to start up the ignition. In a simple way, the air filter is taken off, and then the cotton yarn is dipped in the diesel fuel and put into the intake pipe to start the ignition. This is a very injured machine, because the impurity in the air will enter the cylinder, causing the piston and other parts to wear and damage the machine.
5. start the machine in a hurry without preheating
In order to be faster and simpler, there are many machine hands in the wrong way of starting the machine, such as not preheating to start the engine in a hurry, this is also very hurt, to master the correct preheating method, before the excavator start the correct preheating operation check is: first press the preheat switch, preheating 10 seconds to start the engine, to the engine, to the engine Smooth operation, and check whether the meters and indicators are normal.
6. non warm machine direct operation excavator
After the start of the winter excavator engine, the machine hands immediately go to work, no warm machine directly start operation, this is strictly prohibited. The warm machine operation is essential, the warm machine mainly includes the engine warm and hydraulic oil preheating, the engine should start at low speed and not exceed 5 min, then turn the fuel control knob to low speed and high. At the center of the speed, about 5 min. at medium speed operation in no load condition, remember to start construction work after the warmer is over.
7. baking oil bottom shell with open fire
It is quite dangerous to use an open fire to bake the oil pan when operating the excavator in winter. It is very easy to burn the oil in the oil pan, cause the lubricating property of the oil to decline, and cause the heavy wear of the machine. In the serious case, the accident of burning the machine will appear.
8. do not care about the insulation of the equipment
Who says winter excavators do not need thermal insulation? In winter, you should take good care of your machine. After the winter work, don't forget to cover your engine with a thermal insulation curtain, heat preservation cover, and block the wind in front of the radiator in front of the radiator when necessary.
9. improper walking operation
When the excavator turns on the field, we should pay more attention to the walking, and remember to walk more slowly in the winter, avoid sliding on the slope and so on. Do not swung in the direction and the body of the car, so it is easy to cause the lateral gliding and lead to the dangerous situation; the excavator walk away from the surrounding obstacles as far as possible to avoid parking. Collide with a barrier.
10. disregard of the excavator after the shutdown
Do not think that the work is finished, you can put the excavator aside, this idea is dangerous. After stopping the machine, the mud and water on the machine body should be cleared to prevent the mud and dirt from entering the seal with the water drop. The position of the machine is very important and should be parked on the hard and dry ground. It is to drain the accumulated water in the fuel system to prevent freezing.
