The weather is extremely cold and the climate is dry, and various conditions that are not conducive to the normal life of domestic excavator parts have appeared. We cannot change nature, but can only solve this problem according to more scientific and effective methods. Domestic excavator parts manufacturers have summarized five points for our reference:

1. Domestic excavator parts manufacturers remind us to pay attention to fire prevention

1. The excavator should be prevented from touching the wires during transportation, walking, and excavation, otherwise it will cause serious casualties.

2. The electrical appliances and wiring in the domestic excavator accessories should be checked frequently. When it is found to be damaged, damaged or aging, it is necessary to replace it in time to prevent the electrical wiring from short-circuiting and causing a fire.

3. Keep the wire connectors clean and securely fixed, check whether the wires are loose or damaged every day, tighten loose connectors or wire clamps, rest or damaged wires.

3. Do not place flammable materials inside the excavator, beware of fire.

4. When refueling, it is necessary to stop the engine. In a place far away from the fire source, refueling cannot leave the machine.

5. When refueling, do not allow the fuel to spill onto the overheated exterior or domestic excavator parts of the electrical system.

6. After refueling, wipe off the spilled fuel or engine oil, and tighten the fuel and engine oil tank caps.

7. Timely remove the leaves, wood chips, paper chips and other combustible materials that are accumulated or stuck to the engine, exhaust pipe, muffler and the engine compartment.

8. Do not place oil-soaked rags in the machine to prevent spontaneous fire and burning.

9. The user should be equipped with a fire extinguisher in the machine, and put it in a handy place.

10. When welding the machine, it is forbidden to do it without isolating the hydraulic oil pipeline and the fuel pipeline.

11. To prevent fires caused by hydraulic pipelines, check whether the clamps, guards and cushions of all hoses and pipes are firmly fixed in place. If they are loose, they will cause a sensation during operation and rub against other domestic excavator accessories. . The hose is damaged and high-pressure oil is sprayed out, causing fire damage or serious injury.

12. The battery should be kept away from fire and high temperature, otherwise it will cause explosion.

13. For excavators with a sealed cab, check the tightness of the intermediate partition to prevent engine exhaust gas from entering the cab to cause driver poisoning.

14. It is forbidden to work in poorly ventilated areas to prevent the driver from suffocating.

15. In the event of a fire, do not use water to extinguish the fire. Powder fire extinguishers or sand should be used to suppress the fire. Covers or tarps can also be used to extinguish the fire.

Second, domestic excavator parts manufacturers teach you how to choose diesel

In winter, you should bring a bottle of engine fluid on the excavator. The fuel can also be selected according to the temperature. Now most excavators use diesel engines. The editor also collected some materials for our reference.

The classification of diesel oil is based on the freezing point of diesel oil. The light diesel oil currently used in China is divided into 7 labels according to the freezing point:

10# Diesel: suitable for high-speed diesel engines with preheating equipment

5# Diesel: suitable for use when the temperature is above 8℃

0# Diesel: suitable for use when the temperature is between 8℃ and 4℃

-10# Diesel: suitable for use when the temperature is between 4℃ and -5℃

-20# Diesel: suitable for use when the temperature is between -5℃ and -14℃

-35# Diesel: suitable for use when the temperature is between -14℃ and -29℃

-50# Diesel: suitable for use when the temperature is between -29°C and -44°C or below this temperature

It is recommended that we pay more attention to the weather forecast and choose different grades of fuel according to the appropriate temperature.

Third, the solution to the cold weather

There are many reasons why the excavator cannot be started in winter. In terms of troubleshooting the cause of the machine, there are the following common problems with domestic excavator accessories:

1. The battery loses power 2. The number of revolutions is not high 3. The cooling water is frozen

Let's deal with these problems one by one. Let's start with the principle of the battery in the domestic excavator accessories. The simple understanding is that the sulfuric acid ions and water molecules in the battery generate electricity through collision. In winter, the temperature is low, the gap between sulfuric acid ions and water molecules is large, and the moving speed becomes slow, which shows the lack of battery power. Then the maintenance of the battery in winter is also extremely important. Sometimes it can be found that even if the main power switch is turned off before get off work, the battery is still lacking the next day. The safest way is to remove the battery after get off work and store it in a cool, cool, Dry local. Xiao Hei often encountered this problem before, so every day before get off work, the battery is removed and placed in the cab, but we all know this is unsafe, so we don't recommend it.

If the speed is not high, the main reason is that the preheating is not sufficient

Domestic excavator parts manufacturers have found that general preheating is divided into two methods: air preheating and incinerator glow plug heating preheating. Ordinary engines are air preheating. We can find that the old excavators have no preheating function. , It is often necessary to spray engine fluid to help warm up, but now many new machines have this function, usually in the cab to start the switch. Before starting the excavator, it is generally preheated for 5-10 minutes before starting the excavator.

EFI diesel engine preheater for domestic excavator parts

It is better if the cooling water is frozen. Draining the water before being frozen can prevent this problem. In winter, we are accustomed to adding antifreeze to the excavator, but it should be noted that it must not be mixed with water, otherwise the effect will be greatly reduced. In some places in the south, the temperature is not low, and there are only a few days of rain and snow. Then, before the rain and snow come, only the cooling water needs to be drained. The domestic excavator parts manufacturer reminds you to work at idle before turning off The temperature of the cooling water drops below 60°C. The water is not hot to your hands. Turn off the fire and release the water. Use a bucket to store the discharged water in the cab. It is possible to add it the next day. Of course, in the case of conditions, adding appropriate hot water is also a method, but do not pour hot water on other parts.

Fourth, domestic excavator parts manufacturers prohibit the use of these wrong methods

1. Start with an open flame

Some people remove the air filter of the domestic excavator accessories, dipped the cotton yarn with diesel oil and ignited it as a firelighter and placed it in the intake pipe for combustion-supporting start. They even used methods such as "fire roasting fuel tank" and "smoke engine". This may seem like this, but it actually damages the engine at least and burns down the machine.

2. To release the water too early or not to release the cooling water

If it is not handled properly at this time, it may appear that the engine block expands or shrinks and appears to be cracked.

3. Choose any fuel

The low temperature in winter makes the fluidity of diesel oil worse, the viscosity increases, and it is not easy to spray, resulting in poor atomization. Therefore, the diesel model should be selected according to the local minimum temperature of 7-10 ℃ at that time.

Five, domestic excavator accessories editor's opinion

1. Work the excavator at a low idling speed for at least 5 minutes before use to allow the engine to warm up. Engage and separate the joystick controller. To speed up the preheating of hydraulic components. When preheating the excavator at idle speed, please observe the following propositions:

A. When the temperature is higher than 0℃, the engine will warm up for about 15 minutes

B. When the temperature is lower than 0℃, the engine will warm up for about 30 minutes

C. When the temperature is lower than -18°C or the hydraulic function is lagging, a longer warm-up time may be required.

2. In order to preheat the hydraulic oil, turn the engine speed knob to the middle engine speed. Let the engine work for about 5 minutes and move the joystick without interruption.

3. Turn the engine speed knob to the maximum engine speed and repeat step 2.

4. Operate all the joysticks in a cycle to make the hot hydraulic oil flow into each hydraulic cylinder and hydraulic oil circuit.

5. Keep an eye on the gauges and indicator lights of the domestic excavator accessories during operation. Note: Keep the engine working at low speed before the engine oil pressure indicator light goes out. If the indicator light does not go out within 10 seconds, you should stop the engine and do it before restarting Find out the cause. It is not ruled out that the problem will cause engine damage.
