Hydraulic Paver For Maintenance

AKW GROUP | Updated: Jun 20, 2017

Hydraulic Paver I believe that the majority of friends in the use of paver in the process, a large part of the time is its maintenance. Among them, some maintenance is afraid of the invasion of impurities. In the process of preventing impurity from entering our paver, the hydraulic filter plays an important role.

It is like people's skin, hydraulic oil to resist the outside of the impurities. Of course, Hydraulic Paver the hydraulic filter in the use of a period of time, it will fail. So we have to regularly replace the hydraulic filter and hydraulic oil.

The first filter is replaced after the first 125 working hours, and the filter is changed every 500 hours, and the filter is replaced every time the oil is changed.

Need to pay special attention to 1, the pipeline system of oil leakage 2, the hose bend 3, the correct connection of hydraulic components 4, oil cooling system dirt 5, heat sink should avoid dirt!

1), the first movement speed may be because the oil return tube without oil, no back pressure, and then exercise, the return pipe may be back pressure, Hydraulic Paver look at what you have the back pressure factors, such as throttle use Of the diameter is correct, the throttle valve is regulated flow is too small, check valve spool is blocked.

2), the piston on the ring is damaged or the wrong way to install, so that the hydraulic cylinder to produce a serious internal vent.

3) the hydraulic cylinder is too large, the selected valve and pipe diameter is too small to meet the flow requirements?

4), you clean up the oil filter or oil return filter? May be back to the oil filter blocked.

 5), whether the system pressure measurement, whether the system pressure is not up to the requirements, you can re-set the relief valve.

4. If it is caused by the flow and pressure of the pump. It is best to re-selection, because the general quantitative pump flow and speed requirements of the factory has been clear, Hydraulic Paver after the impact of changes in the life of the pump. And if the pump pressure and flow has changed, the entire system components are affected, can bear, have to consider.

Hydraulic system failure is often the result of multi-faceted factors, so the analysis of the fault must be clear before the principle of the hydraulic system, characteristics, Hydraulic Paver and then according to the fault phenomenon to judge. There are some tips on finding the cause of the fault on the site. The most common method is to reverse the components, remove the load, etc., if the reverse component failure also reversed, it is proved that the component is a problem; if removed Load, failure disappeared, the problem is also understood.

In short, there is a purpose, there is a direction to gradually narrow the scope of the fault to determine the fault area, location or a hydraulic component is necessary, Hydraulic Paver avoid chaos, chaos. To avoid the blindness of the analysis, because the hydraulic flow within the pipeline flow conditions, parts of the hydraulic parts of the action, seal damage, etc., is intangible, invisible. Hydraulic Paver Statistics show that more than 70% of the hydraulic system failure directly or indirectly from the maintenance of improper or hydraulic oil pollution. Therefore, it is important to maintain the cleanliness and good maintenance of the hydraulic oil.
