6 INTRODUCTION - GENERAL INFORMATION Carefully read the use and maintenance manual before start-up the motor. The use and maintenance manual must be placed near to motor installation location in order to guarantee operators easy access to the instruction manual. For further information please contact Italgroup. Motor description IAC series motors are dual displacement radial piston hydraulic motors (generally indicated as LSHT motors, low speed high torque motors) with a rotating shaft () and a stationary housing (). The pistons (3) are located radially and the working fluid provide the mechanical force that push the pistons against the eccentric cam (4), providing the shaft ouput torque. The inlet and outlet flow to and from the pistons is regulated by a distributor (5) that provides the oil distribution correct timing. The pistons transfer the forces to the eccentric shaft through a connecting rod (6). Acting in the adequate way (increasing or reducing the oil flow coming from the pump) the motor rotational speed can be increased or reduced. In addition, there is an hydraulic mechanism (7) that control the motor displacement There are two pressure commands (8 and 9) that are connected to the two displacement change pistons: an external valve (that can be for example a solenoid operated valve or an hydraulically operated valve) supplies pressure to one of the two pistons, depending by the user needs. The pistons move and therefore pull the eccentric cam, this cause the displacement variation. In this way we can have two different displacement in the same motor. Pag. 4 IAC rev. - April 5

18 HYDRAULIC FLUID RECOMMENDATIONS Fluid selection In general, we recommend the use of hydraulic oils with minimum viscosity index of 95, with anti-wear additives (ISO HM and HV). Once normal working temperature is reached, the drain oil viscosity must be at least 35-5 cst, preferably in the range from 4 to 6 cst. HE oils (ecological fluids) are allowed, but must be used with particular attention, because them can influence the motor seals compatibility, and can reduce motor performances and life. Please contact us in case of HE oils usage. Optimal viscosity selection Referring the first approximated selection to the room temperature, we advice the following: Room temperature Oil - C/ C BP ENERGOL HLP HM -5 C/+5 C BP ENERGOL HLP HM 3-8 C/+5 C BP ENERGOL HLP HM 46 C/+ C BP ENERGOL HLP HM C/+3 C BP ENERGOL HLP HM - C/+5 C BP BARTRAN HV 3-5 C/+ C BP BARTRAN HV 46 C/+3 C BP BARTRAN HV 68 ATF (automatic transmission fluid) oils, SAE --3 W oils, multigrade motor oils (SAE 5 W 4, W 4), universal oils, can also be used. Always fill the motor (please refer to the DRAIN RECOMMENDATIONS section) with the selected hydraulic fluid before motor start-up. During cold start-up avoid high-speed operation until the system reach the working temperature, in order to provide an adequate lubrication. Every 5-8 C of increase respect to the optimal working temperature for the selected oil, the hydraulic fluid life decrease of about 4-5% (refer to OXIDATION section). Consequently, the motor lifetime will be affected by the working temperature increase respect to the optimal working temperature of the selected oil. The maximum continuous working temperature is 7 C, the temperature must be measured from motor drain line. If the motor doesn t have a drain line, the temperature must be evaluated at the return line port. Fire resistant oil limitations Max cont. Pressure Max int.

19 HYDRAULIC FLUID RECOMMENDATIONS Filtration Hydraulic systems oil must always be filtered. The choice of filtration grade derives from needs of service life and money spent. In order to obtain stated service life it is important to follow our recommendations concerning filtration grade. When choosing the filter it is important to consider the amount of dirt particles that filter can absorb and still operate satisfactorily. For that reason we recommend filters showing when you need to substitute filtering cartridge. 5 μm filtration required in most applications μm filtration in closed circuit applications Oxidation Hydraulic oil oxidizes with time of use and temperature. Oxidation causes changes in colour and smell, acidity increase or sludge formation in the tank. Oxidation rate increases rapidly at surface temperatures above 6 C, in these situations oil should be checked more often. The oxidation process increases the acidity of the fluid; the acidity is stated in terms of the neutralization number. Oxidation is usually slow at the beginning and then it increases rapidly. A sharp increase (by a factor of to 3) in neutralization number between inspections shows that oil has oxidized too much and should be replaced immediately. Water content Oil contamination by water can be detected by sampling from the bottom of the tank. Most hydraulic oils repel the water, which then collects at the bottom of the tank. This water must be drained off at regular intervals. Certain types of transmission oils and engine oils emulsify the water; this can be detected by coatings on filter cartridges or a change in the colour of the oil. In such cases, obtain your oil supplier advice. Degree of contamination Heavy contamination of the oil causes wear rising in hydraulic system components. Contamination causes must be immediately investigated and remedied. Analysis It is recommended oil being analyzed every 6 months. The analysis should cover viscosity, oxidation, water content, additives and contamination. Most oil suppliers are equipped to analyze oil state and to recommend appropriate action. Oil must be immediately replaced if the analysis shows that it is exhausted. IAC rev. - April 5 Pag. 7

20 DRAIN RECOMMENDATIONS Motor axis horizontal Motor axis vertical, shaft down Motor axis vertical, shaft up Leakage line connection Always fill the motor with hydraulic fluid before start-up. Arrange piping in a way that the motor cannot drain off and cannot generates air bubbles into the motor case. Under certain conditions may be is necessary to arrange a check valve in order to help avoiding the motor drain off. Always check carefully that the leakage line pressure doesn t overcome bar pressure: therefore leakage lines must be shorter as possible and with a minimum flow resistance. Pag. 8 IAC rev. - April 5

26 INSTRUCTIONS AND ADVICES The motor must be installed using the correct screws size (we recommends the use of.9 and.9 class resistance fixing screws) and must be placed on a structure that is capable to correctly support the motor during functioning: for this reason the structure must not only be able to support the motor weight but must also assure the absence of vibration during operation and must win the reaction forces that are generated by the working torque. Regarding the motor fitting design, the concentricity between the centering diameter (spigot) and shaft (both splined or parallel) must be assured with a strict tolerance (please refer to the following general indication). If the concentricity between the shaft and the centering diameter and/or fixing holes is not respected, in the worst case the motor can have an unusual failure or can work only with low performances. Splined adaptors (sleeves) are available upon request. Motor installation Hoses and piping must be clean and free from contamination. Use proper hoses for oil connection, both for inlet and outlet main ports, displacement change ports, and for drain line. Refer to hoses and fitting constructors in order to correctly size and select hoses and fittings. In order to keep control on the oil compressibility keep hoses to the minimum recommended size and select pipelines most rigid as possible. The motor can be mounted in any position (refer also to drain recommendations section). In run-away conditions you must use counterbalance valves. When the motor is installed vertically with shaft pointing upwards, consult our technical department. If the motor is connected to high inertial loads, the hydraulic system must be designed to prevent peaks of pressure and cavitation. 3. B + C D ØA ØB,5 A,5,5 B ØB ØA H6 D C Ø,5 A B 3. A E F.

27 INSTRUCTIONS AND ADVICES Consider the use of relief valves, possibly directly mounted on motor distributor in case the application can generates pressure peaks at the motor ports: the relief valve should be able to discharge all the flow (or at least a good part of it) with a limited pressure increase. Italgroup can provide differents valve types that can be placed directly on the motor distributor (please refer to Italgroup valves technical catalogue). Motor case and pistons must be completely filled with oil before starting. Do not load motor to maximum working pressure instantly. During cold start-up avoid high-speed operation until the system reach the working temperature. Connect the case drain directly to tank, and avoid excessive drain line pressure losses (the case drain pressure must not exceed 6 bar continuous pressure for IAC serie standard motors, contact Italgroup if higher motorcase pressure is needed). The case drain port on the motor must be located on the highest point of the installation to ensure that the motor will always be full of oil. (See drain recommendations page for more details) High pressure applications Back pressure Maximum oil temperature must not exceed 7 C. Heath exchangers must be used with higher temperatures. The operating fluid viscosity must always be higher than a certain minimum value (see fluid recommendation section) in order to guarantee an optimal motor internal lubrication. When the working conditions cause the motor case overheating above a critical value, the motor flushing is required. Flushing consists in the introduction of fresh oil (taken from the hydraulic circuit) into the motor case. Oil must be taken from the return line to avoid internal motor damage (for standard motors the continuous motor case pressure must be maximum bar). Flushing is an important operation that can be very effective to improve motor lifetime with heavy duty working conditions and improve the motor mechanical efficiency. The motor flushing, if the motor works in one direction only, can be easily performed connecting the motor return line to the lowest motor drain port. The highest motor drain port must be connected to the tank. For D75 and D9 flow distributors, the side /4 metallic plugs can be used for flushing circuit installation: infact the plug (corresponding to the return line port) can be removed and the connection between motor low pressure port and motor case can be correctly realized. If the motor axis is not horizontal and/or the motor works in bidirectional operation, please contact Italgroup technical department, that can assist you to advice how to perform the desired operation in the best way. Just for your reference, Italgroup can provide you flushing valves in order to perform an effective flushing circuit. In case of high pressure applications, a Nitemper treatment on cylinders or in the motor body is suggested to increase wear and tear resistance. Back pressure limit for IAC series motors is 7-8 bar (back pressure occurs for example when hydraulic motors are installed in series circuit). High back pressure values are often responsible of motor overheating, so if drain temperature reach values that bring the oil viscosity under the recommended limit (refer to fluid recommendations section), perform appropriate motor flushing and/or reduce the back pressure.

28 INSTRUCTIONS AND ADVICES Boost pressure When the motor runs at a speed that can cause pumping effects, a positive pressure it is needed at the motor ports.the minimum required pressure at the motor ports can be estimated basing on different parameters, using the following formula: p = + pc + CHnV Where p is the boost pressure, pc the case pressure, n the rotation speed, V the motor displacement, and CH is a constant, depending by the motor serie. Motor IAC H IAC H3 IAC H4 IAC H5 IAC H6 IAC H7 Displacement change CH,5 * -9,5 * -9,5 * -,5 * -,4 * -,5 * - Example: We suppose (IAC H4 motor): n=4, pc=3, V=8 [cm3]; We can calculate the boost pressure as follows: p = + 3 +,5 * - * 4 * 8 = , = 9, The displacement change can be performed in different ways. The user can use an internal or esternal pilot. In addition Italgroup can supply a Cetop 3 fitting with or without Cetop 3 displacement change valve (with electric or hydrauilic control). When the displacement change ports are not feeded with pressure, the motor remains at the maximum displacement: to perform the displacement change, the pilot pressure must be at least /3 of the motor working pressure. A minimum pressure of around 3,5 bar (the value is approximate and can have variations in function of the operating parameters) is needed in order to activate the displacement change mechanism. Please note that in freewheeling operation it is necessary supply the displacement control mechanism with an external supply pressure/flow source. This external supply source will assure that the motor displacement during the freewheeling operation remains fixed at the minimum value, avoiding IAC motor damage. The oil flow rate required to perform the displacement change can be estimated in function of many different parameters; the most important factor that determinate the required flow rate is the motor case internal leakage. The flow rate that is shown in the next table must be considered as an indicative value that depends by many system parameters and working conditions. Pag. 6 IAC rev. - April 5

Minimum speed is very low and can reach values near to - rpm (depending on motor displacement). In case of low speed vibration a reasonable back pressure can eliminate or minimize the vibration and noise level (a general guideline value can be defined by 5-8 bar back pressure). For more information please contact our technical department.

31 INSTRUCTIONS AND ADVICES Basic displacement change hydraulic circuits The typical displacement change circuit is shown on the left; the displacement change pressure is taken from the higher pressure motor port (if motor works in a bidirectional way a shuttle valve, SV, is needed to make the selection between the higher and lower pressure port). To order the shown motor assembly the ordering code is XY (the displacement change port fittings are /4 BSP female thread). In all circuits, A and B identify the motor inlet/outlet port (the motor is fully reversible, can work with same behavior in both directions), whereas L identify the motor drain port. IAC motor L A B Y X SV Y XY-SV C3-SV X Italgroup can provide a special motor distributor with integrated shuttle valve (SV). The ordering code is XY-SV for displacement change fitting /4 BSP (female threads) or C3-SV for cetop 3 displacement change valve fitting. DCV if required IAC rev. - April 5 Pag. 9

32 INSTRUCTIONS AND ADVICES Italgroup can supply solenoid or hydraulic operated displacement change valves, directly fitted on the motor (please refer to ordering code section and dimensional drawings for more information). The circuit on the right shows a complete assembly with displacement change valve and shuttle valve, included in the motor assembly. The ordering code in this case is C3- SV or C3-4 SV, in case the DCV is solenoid operated, or C3-HY SV if is hydraulic operated. Advanced displacement change hydraulic circuits (with external supply source) IAC motor L A B Y X SV DCV C3-XX SV When the working pressure can reach very low values, lower than the minimum pressure that is required for displacement change (approximatively 3,5 bar in normal conditions), an external displacement change pilot supply source is required. Please refer to the circuit on the right. The circuit on the right shows an integrated SV valve with external pilot supply: when the motor working pressure is lower than the external supply relief valve setting, the displacement change pressure is taken from the external supply source. When motor working pressure is higher than the external supply relief valve setting the displacement change pressure is taken from the motor ports. The circuit refer to the XY displacement change port configuration. IAC motor L A B Y X SV Y X P XY-SV CV DCV if required M Pag. 3 IAC rev. - April 5

33 INSTRUCTIONS AND ADVICES Displacement change hydraulic circuit (continue from previous page) Small displacement freewheeling circuit The complete assembly with motor, displacement change valve DCV and integrated shuttle valve SV can be equipped with an external pressure supply source. Please refer to the circuit shown on the right. The ordering code in this case is C3- CSV or C3-4 CSV in case the displacement change valve is solenoid operated, or C3-HY CSV in case the displacement change valve is hydraulic operated (please refer to ordering code section and dimensional drawings for more information). IAC motor A L B Y X SV CV DCV C3-XX CSV P M / IAC motor L Y X A Y XY X C3 B SV DCV AC if required M Selecting a zero displacement IAC motor, the motor can run without load at high speed, resulting in a minimum motor torque requirement. The maximum working pressure shown in the motor technical data or the zero displacement code are relatives to a rpm shaft speed. If the output shaft speed is less then rpm the maximum working pressure can be slightly increased. Consult Italgroup technical departement to obtain more details. For output shaft speed higher than rpm the application duty cycle must be considered by Italgroup. When the motor is running at high speed, a minimum pressure must exists at the motor ports (see boost pressure paragraph), but in all cases this pressure must not exceed the maximum working pressure reported in the zero displacement code motor technical data. IAC rev. - April 5 Pag. 3

34 INSTRUCTIONS AND ADVICES To perform the boost circuit, an anticavitation valve (AC valve, referring to the diagram on the previous page) must be present, in order to avoid cavitation. A crankcase flushing flow is highly recommendend in freewheeling operation, to control and reduce the motor temperature rise during the freewheeling. If the motor running speed is between and 5 rpm, a 5 l/min (indicative value) flushing flow is compulsory. Bearings The bearing life depends by different factors, like bearing type, motor speed, working pressure, external loads, duty cycle, fluid viscosity, oil cleanliness, type and temperature. Lifetime is measured by L which is called theoretic lifetime. It represents the number of cycles that 9% of identical bearings can effort at the same load without showing wear and tear. Please refer to bearing lifetime diagrams reported in the following pages to obtain the theoretical bearing lifetime. The lifetimes diagrams shown the L5, median or average lifetime, that can be considered as 5 times L. Please note that the theoretical lifetime can be different from the real lifetime, especially in case of heavy duty applications with continuous work cycle. Please contact Italgroup S.r.l. for more information. Motor creep speed The hydraulic motor is able to hold the load acting as a brake (if proper valves or circuit are considered and installed), but a certain creep speed is always present: this is typical of all brands hydraulic motors. The motor creep speed depends by many factors, like operating conditions (motor displacement and type, pressure load on the shaft, oil viscosity, type and temperature) and are represented in the creep speed diagrams (see performance diagrams for each motor size). The creep speed diagrams are shown for an hydraulic oil at reference conditions of 4 cst. If creep speed is higher than desired value a negative brake can be considered: Italgroup can supply negative brakes that can be fitted to the hydraulic motor. Please contact Italgroup S.r.l. for more information. Pag. 3 IAC rev. - April 5

35 INSTRUCTIONS AND ADVICES Marine painting Special features If needed, special painting or primers are available in order to guarantee optimal protection against normal corrosion and marine environment corrosion. The ordering code is MP. Please contact Italgroup S.r.l. for more information. Speedy-sleeve A special inox sleeve is available upon request. In case the motor is used in aggressive medias or environments, this can be very useful in order to protect the motor shaft surface located in proximity of the motor shaft seal. This improves the shaft and seal endurance respect to wear and corrosion. The ordering code is SPSL. Please contact Italgroup S.r.l. for more information. High pressure shaft seal Standard IAC motors are supplied with high pressure shaft seals, the continuous drain pressure must be maximum bar, whereas the peak drain pressure must be maximum 5 bar. In case the drain line can or must has a higher pressure, special shaft seals are available upon request. The ordering code is HPS. The drain pressure with HPS shaft seal can reach -5 bar continuous pressure and 3 bar peak pressure. The HPS shaft seal is bi-directional also, so it can be used for example in underwater applications. Please contact Italgroup S.r.l. for more information.
