KHJ10950 Sumitomo Hydraulic Pilot Filter element Excavator Spare Parts

KHJ10950 Original ELEMENT;OIL FILTER SH130-5/200-5/210-5/200-5/350-5/360-6/450-5/480-6 SUMITOMO Excavator Filter

Sumitomo hydraulic pilot filter element with good quality and good property made of imported materials easy to clean and easy to install to protect the machinery

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.
