????Failure of the hydraulic system of more than 80% by the oil pollution caused by oil pollution control can extend the service life of hydraulic components and hydraulic oil,
ensuring continuous and reliable operation of the system.
????Oil pollution control hydraulic system there are two main measures: First, to prevent contaminants entering the system, and second pump station oil filtration and
purification.
First, to prevent contaminants into the system
????Rather to prevent the disease from the mouth. Sealed tank design, pay attention to remove components and piping impurities good selection of filter performance air filter,
install the system, the fuel tank using a good dust-proof seals, injection system with new oil through strict filtering, which is to prevent the ingress of contaminants Systems measures.
?
Second, hydraulic oil filtration and purification
Suction filters, return line filter and oil filter oil filtration and purification is completed, use filters to note the following:
?
A suction port filter should be used filtering accuracy is low, the flow capacity of the filter, flow capacity of the poor is likely to cause a hole suction filter, oil filter
for blocking large particles of pollutants into the hydraulic pump, prevent suspended in oil bubbles enter the system. Piston generally do not use suction filter.
Two line filter is usually installed in the upper reaches of the more important elements, filtering accuracy than element friction with the gap servo system passing through the
filter Do not use the bypass check valve, filter resistant to high pressure.
3 low pressure back to the oil filter, the coarse rod system, traffic flow through the filter is greater than the pump flow, flow to pay attention to the choice of filter, the
filter pump flow rate is greater than the flow rate and the cylinder piston front chamber area ratio product.
Select 4 filter traffic: appropriate to increase filter flow will extend filter life.
5 precision filter selection: the choice of the system's main filter, such as precision when passing through the filter, the filter should be able to remove particles of
hydraulic components deputy campaign dynamic oil film thickness, because the particles of this size into motion once Pair the gap, will cause surface wear member, and the gap increases, so that
the size of the larger particles into the gap, cited interest further wear, causing severe wear of "chain reaction", "chain reaction" as a bit like a pyramid scheme , can quickly lead to
failure of components.
Pollution control hydraulic system described above is mainly for solid particles, the hydraulic system also includes a water and air pollution, harm can not be ignored. . . . .
. In short, the whole process of hydraulic system design, manufacture, installation, use and maintenance of the hydraulic system should pay attention to pollution control.
Hydraulic Tips:
1 human eye visual limit is 40μm, causing hydraulic components wear particles are generally less than 40μm and invisible;
? 2 filtration ratio definition: x = the number of particles larger than the size xμm of upstream / downstream greater than the number of particle size xμm;
x: the median particle size, unit μm;
In the hydraulic servo system generally requires the use of filter than β3 ≥200 filters.
Leakage of hydraulic cylinders for whatever reason, how to do?
First, the external leakage of hydraulic cylinders
????Leakage of fluid leaking from the Run refers to the hydraulic cylinder at each Mifengbuyan outside atmosphere, the most common external leakage following three:
????1. Hydraulic cylinder liner and the cylinder head (or guide sleeve) sealing parts oil spills. Agricultural machinery cylinder liner and cylinder head more use of threaded
connections, then the 0-ring at threaded port. When leakage occurs here more for O-ring damage, as long as the replacement of suitable new O-ring can be solved question.
????2. The piston rod guide relative movement of the sleeve face outward leakage. Here the piston rod is usually sealed with O-rings or the Y-ring, because it is dry and seal
friction between the piston rod, friction is large, tend to increased wear of the seal; Further piston rod extended surface various impurities into contact, and often the piston rod surface
wounds, dry ditch, pitting or rust play, etc. exacerbate seal wear. even cuts seals. Therefore, when there is leakage occurs, except replace the seals, we must also check whether the damage
piston rod. If the rod is damaged, it can be used to clean gasoline. Dry exercise with metal glue smear lesion. Then seal back and forth movement of the piston rod scrape excess glue on the
piston rod, et adhesive is fully cured before put into use. If the guide sleeve wear, can be processed with an inner diameter slightly smaller than the guide sleeve to be replaced. The new
guide sleeve than the original inner diameter should be reduced 0.15uun, this new guide sleeve can be installed seal properly, it can make up the gap wear and thus better able to play a
seal.
