Six good habits extend the life of your excavator

Do not know everybody found no such a phenomenon, we sometimes see some excavator more than 10000 hours machine condition is still very good, at the site of walking on the powerful, compound action smoothly, the loading speed is also good, but also the fuel consumption is not so high, and some mining machine in just two thousand or three thousand hours, there should not be at this time problems, such as engine black smoke, my car, the lift arm speed is slow and so on a series of problems. Certain friends will ask, different brands of machines will certainly appear this situation, after all, some brands are also much higher prices. Of course, the machine manufacturing level of different brands are different, but many of the same brand of machine will also appear some machine is in good condition "vintage car" and some one or two years of excavator wrong, so this is why?

Xiao Bian or more recognized, we engineering machinery field widely circulated in a word, called three extension seven points support. It is important to select a machine with a high technological level, but the inspection and maintenance in the later stage of use is more important.

Here, Xiao Bian summed up some experience, hope can let you love better service for you.

1. daily inspection and maintenance

Beat butter regularly to reduce wear

Talking about the daily maintenance of the excavator, I think the first thing everyone thinks of is the butter. Yes, hard to butter can reduce the wear of excavator various moving parts, prolong the service life of the shaft pin and bush, there is a driving process for premature due to excessive wear of the pin bang when sound.

Check the amount of oil every day

But butter is just the first step in daily maintenance. You need to open the hood and check the oil content, except that you need to grease all the grease where you need to work before you work. The lack of oil is no laughing matter, it is easy to cause the engine cylinder or the tile burning accident.

Check antifreeze levels

Check tank. The water tank to the engine cooling function is through coolant circulation, lack of antifreeze if not timely supplement are likely to cause the engine cylinder. Routine inspection can be done by observing the expansion tank calibration or opening the tank lid to check the antifreeze content.

Water the oil-water separator regularly every day

Water separator. Now domestic oil, I think we are very clear, even PetroChina or Sinopec's diesel quality is not very good, not to mention many excavators plus diesel oil provided by the site. Since you can not guarantee oil quality from the source, then the diesel filter is particularly important, and every day before the ignition engine, it is necessary to take a look at oil-water separator, timely discharge oil-water separator moisture. Xiao Bian previously encountered such a situation, a dump truck morning beat the fire, managed to hit a minute not stalled again, the engine began to think what fault occurred later all line check found when the oil-water separator has been filled with water, sucked into the engine is not the most diesel. Water, it is no wonder that not a car!

Hot car. The car is very easy to be ignored, may in the winter when everybody will take the initiative to the engine a few minutes, but in the summer a lot of machine hand ignored the engine work. In fact, whether in winter or summer, the work of a heat engine is indispensable. First, before the engine starts, the engine oil is deposited in the oil pan. The engine can pump and pump the oil evenly to each part. Second, the normal work of the engine is also required a certain temperature, heat time is to the engine of our own heating time, wait until the temperature reaches the right temperature and then work can reduce engine wear, prolong the service life.

2. regular maintenance

An important part of regular maintenance is also prolong the life of excavator, according to each machine maintenance manual maintenance time, timely replacement of oil filter, hydraulic oil and hydraulic oil filter, oil is not good for some areas, recommended to choose the advance to replace the diesel filter, conditional can also to install a diesel filter. For some long-term in a large dust working environment of the machine, in addition to replace the air filter, usually also can blow dust filter, the timely removal of the filter core. In addition, gear oil is also easy to be ignored by everyone a maintenance point, excavators need to add gear oil place, rotary motor reducer and walking motor reducer. In addition to routine inspection of gear oil content, gear oil must also be changed regularly.

3. use high quality parts and accessories

Each cartridge excavators are between the workpiece and the impurity barrier, direct contact with the hydraulic oil cylinder in hydraulic pump, through the filter, diesel filter through fuel sprayed into the cylinder, so the filter directly affects the life of key parts of excavator. In the regular replacement of the filter, at the same time, select the qualified filter is also very important.

Use a qualified filter cartridge

In addition, the excavator repair process needs to replace parts, but also had better make the choice of original parts or quality guarantee genuine parts, do not covet cheap, practical inferior parts. Like some long life accessories, such as starter, generator, battery and so on, these parts need to be replaced when the best choice of good quality, the price is probably a little expensive, but use a few years down the cost but will lower, better for the machine.

4. use qualified oil

Now in the industry due to the use of counterfeit fake oil, hydraulic oil and make the machine overhaul cases have been few, some fake oil in rapid oxidation, emulsification after a period of time, and even into the milk white liquid, completely lost the lubrication function, this is undoubtedly the engine is a fatal injury.

Metamorphic hydraulic fluid

Xiao Bian previously touched a second-hand excavator, buy back when doing a major maintenance thoroughly to find out the hydraulic oil like milk, oil also sticky massive sludge, fortunately timely replacement without causing major damage to the machine.

So everybody in the new machine warranty time, be sure to use the original authentic oil, for their maintenance after your insurance, best buy oil and hydraulic oil in the regular oil store, not freeloaders using small shops, small workshops for sale.

5. filling qualified diesel

Probably a lot of machine owners are more like straight jet car, there is this idea, I think the big reason is the quality of domestic oil products. Compared with direct injection EFI cars, the car is more delicate, the fuel quality requirements to a little higher. However, whether it is EFI or direct injection vehicles, the choice of qualified fuel is only good for the machine, there is no harm.

The main conditions to choose the best qualified diesel of Sinopec gas station filling in the oil and gas station filling, avoid private diesel, there may be some main excavator working environment is relatively remote, or to use the monthly site site refueling vehicle sent this kind of fuel, the users themselves can not guarantee the quality of oil, so oil filtering this link is particularly important, must be qualified to use filter can even install a filter.

6. good driving habits

In addition, driving habits are also important factors affecting excavator life. Small before the forum saw that the teacher opened the Doosan excavator, more than 6000 hour, excavators of paint are not wipe a little looks like a new machine, according to the master, the Doosan from the new machine to more than 6000 hours he has been in the open, in addition to use on normal maintenance, even pipeline are not burst, large drops of oil pump, the engine is not enough, not to see the nameplate is really can not see is more than 6000 hours by car.

Why does the teacher maintain the excavator so well? In fact, he has his own special opinions about driving habits.

The old master said, is not difficult to paint to protect the "ass", usually pay more attention to observation on the line, to develop good habits of observation, every turn to clear heart swing radius excavators, ensure no debris around, so that can not only protect the excavator, also can ensure the safety of operations. In addition, use the appropriate mode to do the right to live, not purely for fuel-efficient small throttle open heavy work, try to avoid the phenomenon of vehicle hold the artificial reasons, in the dry rock live, have to pull the real stone. Don't get not hard, change an angle to dig a summary sentence is to make the engine work in a soft voice, so that not only fuel but also to machine wear to the minimum.

The teacher also mentioned that the rotary system of excavator is relatively fragile, try to avoid the heavy load of rotary, such as some drivers in leveling when love with rotary to sweep the soil, the rotary system damage is relatively large.

Sum up:

We all hope that our excavator can not malfunction or less trouble, but also hope that the machine can do more than a few years to live, after all, time is money! But the service life of excavators is more grasp in the hand, like a a friend said, machines also have feelings, it is you it is good to you, in fact, this argument is not without reason, to develop good driving habits, do the excavator maintenance work, I believe you can certainly excavator many years of work for you.
