the importance of an efficient filtration the main cause of anomalies in hydraulic systems has to be attributed to the presence of contaminants in the fluid. the nature of the contaminant may be: gaseous, namely air mixed with the fluid; fluid, it depends on water penetrating the fluid; solid, therefore particles of various origins and dimensions. customers who operate equipments are always focused on obtaining the best possible performance, lower energy consumptions and greater respect for the environment. these characteristics can be attained by using top quality components in the hydraulic system for generating and regulating the fluid power, which are also more sensitive to the presence of contaminants in the fluid. starting from these requirements, we understand how important and fundamental it is to prevent the presence of air and water from mixing in the fluid tank by using dedicated solutions. it is also crucial to limit the presence of solid particles in the hydraulic circuit through a suitable filtering system, which is indispensable to maintain the project requirements of the system over time and to keep running costs low. the correct choice of a filter and its optimum position in the hydraulic system requires the same care and experience needed to choose all the other components. the use of filters with larger filtering surfaces reduces, at equal flow rates, the superficial contaminant load and therefore the filter's life is extended proportionally. to maintain the maximum efficiency of the system, the filters must have a clogging indicator showing the differential pressure on the filtering cartridge and to immediately point out when the cartridge needs replacing in order to prevent the by-pass valve from opening. the following factors should be analysed when choosing the ideal filter: the filtration degree required to protect the most sensitive component from contamination the points of the circuit in which the filters have to be installed the working pressure of the system the maximum flow rate and the type of fluid to be filtered the duty cycle the retention efficiency of the filtering cartridge the contaminant accumulation capacity of the filtering cartridge the working ambient temperature each filter used generates a pressure drop that increases continuously as time goes by. this pressure drop represents an efficiency index of the filter itself. when the hydraulic system is about to be assembled, all the components must be perfectly clean and the fluid has to be added through a device complete with a filter. during the test phase, it is advisable to run some work cycles at low pressure in order to create the best possible conditions for all the components. free datasheet http:///

hf 735 2 002 icat022-002 sizing ? pressure drop 2) the pressure drop of the element is proportional with the oil density and kinematic viscosity, therefore for oil with density different to 7.29 lb/gal (0,856 kg/dm 3 ) and kinematic viscosity different to 120 ssu (30 cst) the value of p in the element will be: now you sum the values of the pressure drop of the housing to the value of the pressure drop of the filtering element, always making sure the total p does not exceed the pressure limit of 11 psi (0,75 bar). the total pressure drop of the filter is calculated by summing the pressure drop value in the housing to that in the filtering element. total p p in housing + p in element in the filters of series hf 735 in normal working conditions, the total p must not be more than 11 psi (0,75 bar) whereas, for use in harsh conditions, it must be within 14.5 22 psi (1 1,5 bar). to establish the values of pressure drop involved, the following pages provide some diagrams with curves referred to the use of mineral oils sae 10 with kinematic viscosity of 120 ssu (30 cst) and density of 7.29 lb/gal (0,856 kg/dm 3 ). example calculation filter HF735-20.106-as-fg010-lc-b60-gd-b-dd-g flow rate= 12 us gpm (45 l/min) kinematic viscosity: 120 ssu (30 cst) oil density : 7.29 lb/gal (0,856 kg/dm 3 ) filtering degree: 10 m data obtained from the diagrams: p in housing = 2.00 psi (0,14 bar) (page 4) p in element = 7.25 psi (0,50 bar) (page 5) total p = 2.00 + 7.25 = 9.25 psi (0,64 bar) ( p is lower than maximum value admitted ? therefore sizing is correct). if oil with different kinematic viscosity and different density is used, the values obtained from the diagrams shall be re-calculated considering the following indications: 1) the pressure drop of the housing is proportional with the oil density, therefore for oil with density different to 7.29 lb/gal (0,856 kg/dm 3 ) the value of the p in the head-bowl will be: 02/01.2012 or or p in housing = p of diagram (bar) ? oil density ( kg/dm 3 ) [bar] 0,856 (kg/dm 3 ) p in housing = p of diagram (psi) ? oil density ( lb/gal) [psi] 7.29 (lb/gal) p element = p of diagram (bar) ? oil density (kg/dm 3 ) ? oil viscosity (cst) [bar] 0,856 (kg/dm 3 )30(cst) p element = p of diagram (psi) ? oil density (lb/gal) ? oil viscosity (ssu) [psi] 7.29 (lb/gal) 120 (ssu) free datasheet http:///
