What about the paver?    

Paver is a large construction machinery and equipment, so its use and maintenance is the main concern of the machine owners. However, in life, we may be because of some wrong ideas and experiences, or blindly listen to others talk, leading to the paver for repair and maintenance of the wrong, today Xiaobian for everyone is to visit the.

1 about engines

Excessive oil filling or incorrect marking: the engine should be added the correct labeling of oil, too low labeling will aggravate the wear of the engine, cooling effect is poor; the label is too high will also increase wear, shorten the piston ring life. When the oil in the engine oil pan is insufficient, the crankshaft and connecting rod journal and the main bearing will cause poor lubrication due to the small amount of oil, and the phenomenon of burning tile occurs. But too much oil filling will increase the rotational resistance of the crankshaft, so that the oil splashing to the cylinder wall increases, resulting in the increase of carbon deposition in the combustion chamber. So that the engine output power decline, parts wear intensifies, exhaust emissions exceeded. Therefore, the engine oil quantity should be controlled between the upper and lower scales of the oil dipstick.

2 about fans

Cooling fan belt is too tight: summer temperature is too high, some people mistakenly believe that increasing the cooling fan belt tension will improve the cooling effect of the engine. But the belt too tight will not only make it elongated or broken, so as to shorten the service life of the belt, but also due to excessive tension, resulting in generator, pump bearing excessive load, wear intensifies, engine power consumption increased. Therefore, the tightness of the cooling fan belt should be adjusted according to the technical requirements.

3 about hydraulic oil

When the hydraulic oil is replaced, only the oil in the tank is released: there are many hydraulic components on the paver, and plenty of hydraulic oil is needed. When the hydraulic oil needs to be replaced due to the long time of modification, some people mistakenly believe that only the oil in the hydraulic oil can be light up and filled with new hydraulic oil. But there are many old hydraulic oil in the cooler, the hydraulic tubing and the hydraulic control valve. When the equipment is used, the mixing of the old and new oil will speed up the deterioration of the new oil. The correct steps should first let the oil hydraulic oil hydraulic oil cooler and the cleaning tank after adding new hydraulic oil; and then remove the loop duct, start the engine after low speed operation, the oil pump work, respectively control agencies, by the hydraulic oil will old oil circuit by a discharge, until the oil return duct the new oil outflow so far; finally the oil return duct is connected with the tank, to supplement the new hydraulic oil tank to the specified location.

4 about gear oil

The term does not replace or add gear oil gear oil inferior: as the paver traveling speed is slow, and the original gear oil and long-term use will not change, some people mistakenly think that wear reducer is slow, the market is difficult to buy the original gear oil, speed adjustable goods from manufacturers, at the same time duration and very tight, a lot of drivers to choose the replacement of gear oil or join this round of inferior oil. These practices are not proper, judge whether metamorphic gear oil not only from the color, but also to observe the content of iron, viscosity, gear oil for prolonging the service life of the motor running, maintain the normal operation and play a very important role in the maintenance of normal work, should pay attention to.

5 about bolts

Bolt fastening is too tight: there are many fasteners for bolts and nuts on the paver. In order to make the connection reliable, it should ensure that it has enough preload. But it can not be wrongly considered that the more tightening the bolt is, the greater the torque of the bolt will be, which will not only cause the permanent deformation of the fastener due to the external force too much, but also cause the screw thread or screw broken when the tension is too large. Therefore, the correct bolt tightening method should be based on the location and use of the connector parts, according to the instructions specified tightening torque.

6 about accessory replacement

Replacement parts are not timely: in the use of paver, the construction period is often more tense, and the spare parts of construction units are less, and out of trouble will take some emergency measures, that is to say, live together, let the machine move. While the machine is in this state of long-term use will greatly increase the wear damage, if not timely replacement will cause damage to the assembly or other related parts of the corresponding components, a big problem to repair than timely repair costs several times or even dozens of times the price, but also affected the progress of the project.

7 the wise remark of an experienced person

Superstitious experience: many people mention mechanical maintenance, often think of is disassembly. In fact, with the continuous improvement of assembly process, the quality of materials used in parts continues to improve, such as bearing loose, gear destroyed and other problems gradually reduced, and hydraulic technology, electrical technology is more and more widely used in paver. For example, the scraper does not turn, it is likely that the problem is on the circuit, but not blindly to find whether the stone stuck or bearing loose. For example, solenoid valve, by it to control the action of each part is accurate, once it appears hairpin and other faults, there will be no action or no action at the moment, if only the old experience, from the associated parts to find the reason, I'm afraid it is difficult to troubleshoot.

8 about manufacturers

And manufacturers after-sales service personnel relations: this will be divided into two cases, one is three package period, some parts even if they can repair, but also ask manufacturers to do, apply for replacement assembly. And after the expiration of the three package, as far as possible not to please or less please, but to keep in touch, to some professional technical content of the core components of the repair to consult. With the continuous progress of science and technology, more and more new technologies continue to be applied to construction machinery, as the technical personnel of production enterprises have advantages in the acquisition of new technology. By learning from it, we can make the machine more efficient.

So, everyone in the paver on learning knowledge, must have a rigorous and serious attitude, don't careless, muddle along, so as to better protect their equipment, prolong the service life.
