In the frequent maintenance work, often hidden huge security risks, today we will briefly list these things.

High pressure is very dangerous, common rail tubing shall not be dismantled

With the increasing popularity of electronic controlled engine, the correct maintenance is extremely important for the engine, but when the engine is working, all should not remove high-pressure side of the pipe joints, such as high-pressure tubing, common rail pipe etc..

The pressure of the common rail tubing is very high. It must be removed after the engine stops and the pressure is released. Now the high-pressure common rail diesel engine at work, the fuel pressure can be as high as more than 2000 bar, the pressure is equivalent to a luxury car pressure on a nail cover area of pressure. Under such high pressure, once the common rail tubing joint is removed, the fuel injected at high speed is sure to produce high pressure liquid cutting effect, which is sharper than the knife. Once it is sprayed into the human body or the eye, the consequence will be unimaginable.

The correct method: Baotou North rush heavy truck parts after engine flameout, wait for a period of time, to be completely pressure relief after disassembly and maintenance

The potential killer of tyre bulging

Tire bulging is dangerous, especially the front wheels. In case of running, tires blow up because of bulging tires, which can cause accidents and become even more dangerous on highways. So in the inspection, once found the drum drum should be replaced in time.

At the same time, many truck drivers in the driving process check the tire pressure, often get by with a crowbar etc. to strike the tire to judge the tire pressure is normal, this time because of the high temperature high pressure wheel, tire, tire burst risk will impact a very high, and the truck tire pressure is generally high, once the tire the impact is also great, if the tire bulge, once the impact is more likely to lead to a blowout, resulting in damage It is often seen.

The correct method: Baotou North rush heavy truck parts tire once found bulge, please immediately change, check tire pressure, please use the special barometer.

Prevent the scald from opening the radiator cover of water tank carefully

Just as the vehicle parking or boil directly open the radiator cover, resulting in the scald accident is very much. Once the vehicle traveling in a high temperature or boiling condition, do not immediately turn off, should find a safe place to stop, let the engine idling to heat, don't try to open the tank cover, otherwise it is likely to have a hot liquid spray cause burns. The wet towel can be used to cover the water tank cover and slowly open the first switch (about 1/4 turn). After the steam pressure is released, the water tank cover is completely opened.

The correct method: first, after the engine cooling, advanced pressure relief, and then open the water tank cover, at the same time with wet towels and so on, do a good job of protection measures.

Repair of rotating parts need to be cautious to prevent clothes gloves are engaged in

In the process of maintenance of vehicles, wearing a pair of gloves, a lot of the time is very necessary, especially in winter, dry skin is easy to be scraped and broken, wearing gloves can warm and can play the role of protection. But in the vehicle maintenance time, when the hand must be close to the high-speed rotation of the body, please take off the gloves, because of the high speed rotating mechanism, such as cooling fan belt, often with burr, easily tied to the gloves, then hand is rolled into the inside and cause harm, and in the maintenance of their the cuffs, hem also should be fastened to avoid unnecessary damage. A lot of friends were injured.

The right way: contact rotating parts try not to wear gloves, and fastened his cuffs and hem.

Twisting the ropes to prevent barbaric operations

A lot of people in the installation of the tire or bind goods, have installed it firmly, then strengthened by foot, crowbars and other, but it is prone to foot slip, but crowbars and other tools to rebound wounding, not forced to kick, the probability of such rebound will be greater. The correct method: as far as possible with special tools, safe operation, don't use foot to kick tool.Prevent accidental use of auxiliary starting switch

In the process of maintenance of vehicles often start switch connected to the short side, but if the vehicle is not put in neutral, hastily shorted vice start switch operation will be cars vehicles with mobile stalls, great danger, so this is a lot of previously broken vehicle case. At the same time, it is necessary to point out that some car engine ECU need to receive neutral switch signal, some vehicles have neutral switch short connection phenomenon, so that the risk probability increases greatly.

The correct method is to confirm the gear and operate strictly according to the operation rules.

Air break sometimes is not very reliable

May be a lot of card parked the car after the direct air break that up, but sleep without any anxiety, sometimes we always trust the air break there are not reliable things, vehicle parking brake suddenly lifted the car away things have also occurred, suggest that you try to stop in the parking when not in the formation of the road slope and if the road slope, must be under the wheels of cork bricks or triangular wood, so as to avoid the car suddenly slip and cause unnecessary losses.

The right way is to put bricks or triangles under the wheels so as to avoid unnecessary losses caused by sudden slipping of the car.

The cab must be lifted in place

At the same time in the process of vehicle engine overhaul, often need to type the cab lifting and turning up, but will need to remember the cab lifting end, no locking device can not start, the cab by other forces, it is likely to fall off, resulting in great harm to the maintenance personnel.

Correct method: check and confirm Baotou North heavy truck accessories cab lift in place

There are many security risks in the vehicle maintenance process, more than just cited a part, many are occurring in the process of vehicle maintenance, so the majority of truck drivers should work together to improve safety awareness and avoid injury.
