Mechanical Hydraulic Paver Analytical Method

AKW GROUP | Updated: Jul 12, 2017

Engineering construction machinery in the application of hydraulic system is very common, Mechanical Hydraulic Paver in order to ensure the normal operation of the equipment on the system must analyze the fault analysis method and can find the reasons for troubleshooting. In this paper, Mechanical Hydraulic Paver a number of fault analysis and troubleshooting methods are summarized in the common hydraulic system.

The failure rate of the system debugging stage is high, and the problems are complicated, which is characterized by the intertwining of quality problems such as design, manufacture, installation and management. Machinery, electrical problems, except for the general hydraulic system common faults are:

1, joint or end cover outside the serious leakage;

2, due to stolen goods or oil to the spool stuck or activities are not flexible, resulting in the implementation of component failure;

3, the damping hole is blocked or missing, resulting in instability or pressure on the system can not move up;

4, some valve components missing spring or seal, and even the wrong line to make the action chaos;

5, some variables pump variable control wiring wrong.

A system running early and mid-range failures:

1, joint vibration loose;

2, due to a small number of poor quality or poor assembly, in the short term is damaged, resulting in oil spills;

3, some components due to improper assembly in use caused damage.

When the equipment is running to the mid-stage, Mechanical Hydraulic Paver the various components of the hydraulic components are normal wear and tear due to the difference between the working frequency and the load conditions. At this stage, the fault is characterized by the gradual increase of the failure rate and the increase of the internal and external leakage , The system efficiency is significantly reduced. Mechanical Hydraulic Paver At this point, the hydraulic system and hydraulic components should be fully checked, with serious defects in the components and the actual components of the repair or replacement. Mechanical Hydraulic Paver This means that the equipment to enter the repair or overhaul.

This type of fault feature is accidental mutation, the fault area and the cause is more obvious, including non-human and human factors, such as the accident collision, parts obviously damaged; internal spring break; pipe burst; foreign matter into the pipeline system blockage; Electromagnetic coil burned; Mechanical Hydraulic Paver seal broken; improperly installed components; Mechanical Hydraulic Paver and due to the use of the work environment on the adverse effects of components caused by failure and so on.

Hydraulic system failure in the paver mainly concentrated for the accidental failure, and equipment failure, which accidental occupations occupy the majority.

The hydraulic system of the paver includes walking, scraping, hoisting, and compaction, leveling, lifting, hopper and so on. The following sections analyze each of them separately.

The failure analysis of the hydraulic system of the paver is a complex problem with the combined effects of various factors. Therefore, before the analysis of hydraulic failure must be clear before the hydraulic system of the transmission principle, structural characteristics, Mechanical Hydraulic Paver and then according to the fault phenomenon to determine, gradually in-depth, purposeful, direction to gradually narrow the scope of suspicious, determine the area, location, so that a hydraulic Component. Mechanical Hydraulic Paver Try to avoid the blindness of the analysis. In addition, the choice of hydraulic oil is also affecting the paver hydraulic system can work on the other hand, Mechanical Hydraulic Paver should be in strict accordance with the technical requirements of oil.
