SH350-5/350-3B/300-5/300-6/450-5/480-6 SUMITOMO Excavator Filter
Sumitomo hydraulic oil absorption filter element with good quality
and good properties made of imported materials easy to clean and
easy to install to protect the machinery
Tips:
All images of the filter element are taken in real objects. Due to
the lighting and computer monitor, there may be color difference.
The filter element shall prevail in real objects.
Functions and properties of filters:
1. Functions of filters:
In the hydraulic system, because of the formation of the system or
the system outside the intrusion, the hydraulic oil will inevitably
exist this
In one form or another, the particles of these contaminants not
only accelerate wear and tear on hydraulic components, but also
clog them
Small hole of valve, jam valve core, scratch seal, make hydraulic
valve malfunction. The system failed. So. will
Impurities and contaminant particles in hydraulic oil must be
cleaned. At present, the control of hydraulic oil cleanliness of
the most
The effective way is to use filters. The main function of the
filter is to filter the hydraulic oil. Control of oil
Cleanliness.
2. Performance indicators of the filter:
The main performance indexes of the filter are filtration
precision, flow capacity, pressure loss, etc., among which
filtration precision is the main index.
(1) filtration precision filter works on the principle that the
filter with a certain size of filter hole to filter the sewage into
Line filters. Filtration accuracy refers to the maximum size of
impurity particles filtered from the hydraulic oil by the filter
The principle of filter precision selection is to make the size of
the filter dirt particles smaller than the hydraulic element seal
clearance
Half the size. The higher the system pressure, the smaller the fit
gap of relative moving parts in hydraulic parts. Need a
The filtering accuracy of the filter is also higher. Filtration
accuracy of hydraulic system. It depends on the pressure on the
system.
(2) flow capacity the flow capacity of the filter is generally
expressed by the rated flow rate, which is proportional to the
filter area of the filter element.
(3) pressure loss refers to the pressure difference between the
inlet and outlet of the filter under the rated flow rate. General
filter
The better the flow capacity, the smaller the pressure loss.
(4) other performance other performance of the filter mainly refers
to the strength of the filter element, the life of the filter
element and the corrosion resistance of the filter element
Qualitative indicators such as sex. These performance of different
filters will have greater differences, can be compared to determine
their respective
Advantages and disadvantages.
