3 Catalogue HY29-11/UK Introduction Introduction T7 pumps for variable speed drives Parker Hannifin is proud to introduce in this catalogue its selection of hydraulic vane pumps especially dedicated to variable speed drive applications. The unique technology of theses hydraulic pumps is allowing a wide range of operating speeds, to take the maximum benefits of modern power transmissions. When driven with asynchronous or synchronous electric motors and piloted by frequency controllers, they operate in the most efficient and reliable ways, allowing maximum energy savings. Licensing for these images came with permission from the Parker Hannifin Media Manager collection. Main benefits of variable speed drives Energy savings Up to 7% less electric Energy for the E Motor and less or no cooling for the hydraulic equipement. Lower noise emissions. Lower total cost of the hydraulic system maller pump, less valves, less or no cooling, smaller fluid tank, increased lifetime for the components. Product key features Reliable performance These T7 hydraulic pumps have been designed especially for variable speed drives and are offering a wide speed range. Like all our T7 eries vane pumps, the performances do remain very stable over time, making these pumps an ideal solution for modern electro-hydraulically operated machines. Long lifetime The fully pressure balanced concept increases the pump lifetime over its full operating range while double lip vanes reduce the sensitivity to fluid pollution. Low noise The Denison Vane Technology allows very low noise levels over the entire operating range and during the whole life of the pump. Versatility and compactness With several displacements for the same installation size, the T7 are a very powerful and compact pumps. The various pumping units (cartridge kits) can also be combined with other pumping unit sizes in multiple pumps. This creates a wide range of multi flow pumps, very much adapted to the high power needs. 3 Parker Hannifin Manufacturing France A

The difference between inlet pressure at the pump flange and atmospheric pressure must not exceed,2 bar to prevent aeration. Multiply absolute pressure by 1,25 for HF-4 fluid and by 1,35 for HF-5 fluid. For double pumps, take the value of the cartridge requiring the highest absolute pressure. - Maximum inlet pressure : Read the information on the product key sheet page. tandard shaft seals are limited to,7 bar (1 psig) but some allow 7 bar (1 psig). 6 Parker Hannifin Manufacturing France A

7 Catalogue HY29-11/UK Main Technical Data Outlet pressure range - Minimum outlet pressure : It is recommended to always keep at least 1,5 bar (22 psi) differential between inlet and outlet. - Maximum outlet pressure : Please read the charts in this catalogue for the Max continuous and the Max intermittent pressure ratings. Depending on the average pressure in cycle, either the continuous or the intermittent will be the limit. - Average pressure in cycle : These Pumps may be operated intermittently at pressures higher than the recommended continuous rating when the time weighted average of pressure is less than or equal to the continuous duty pressure rating. This intermittent pressure rating calculation is only valid when the other parameters : speed, fluid, viscosity and contamination level are respected. For total cycle time longer than 15 minutes, please consult your Parker representative.

10 Catalogue HY29-11/UK Main Technical Data Control modes Our fixed displacement pumps, when driven at variable speeds, may operate in hydraulic open loop circuits with various control modes. Flow control mode The pump flow is varied according to the speed command signal of the drive unit. The necessary pressure limitation is achieved by a pressure relief valve in a classic way. Pressure / Flow control mode The pump flow is varied according to the speed command signal of the drive unit which also offers the ability to switch in pressure control mode. This mode requires fast pressure sensors, a servomotor with high dynamics, as well as a fast drive unit. The necessary pressure limitation is achieved by the pump and motor unit that only deliver enough fluid to limit the pressure to the set value. A pressure relief valve remains necessary, but as a safety device only. This control mode may require a specific circuit design. Regenerative mode With a suitable hydraulic circuitry and when driven in its opposite rotation way, the pump may be used as a hydraulic motor, offering an energy recovery functionality. However, for this hydraulic motor function being limited, please consult your local Parker office. Hydraulic fluids Recommended fluids Petroleum base anti-wear, anti-rust and anti-oxydation fluids (covered by Parker Denison HF- and HF-2 specifications). Maximum catalogue ratings and performance data are based on operation with these fluids. Acceptable alternate fluids The use of fluids other than petroleum based antiwear R & O fluids requires the maximum ratings of the pumps to be reduced, when the minimum inlet pressures must be increased. Fluids viscosity The minimum Viscosity Index is 9. The kinematic viscosity range is as below. Over or under these values, please contact Parker. Max. (cold start, low speed & pressure) 2 ct Min. (full speed & pressure for HF-1, HF-4 & HF-5 fluids) 18 ct Max. (full speed & pressure) 18 ct Min. (full speed & pressure for HF- & HF-2 fluids) 1 ct Optimum (max. lifetime) 3 ct Fluids temperatures The usual limitating factor of temperature (low or high) comes from the obtained viscosity. The seals are sometimes the limit. Maximum fluid temperature (also depends on min. viscosity) Minimum fluid temperature (also depends on max. viscosity).

39 Catalogue HY29-11/UK Circuit Design Circuit design Holding the pressure When a high pressure has to be held over a long period of time, the design of the hydraulic circuit must be carefully considered. If the pressure has to be held more than 1 minutes, a hydraulic circuit with an accumulator may be energywiser. Pressure hold function in Flow control mode To improve the energy efficiency of the system, the rotation speed of the pump is usually reduced during the pressure holding steps. Depending on the pressure value that needs to be held, the rotation speed of the pump can be reduced down to its corresponding minimum. pecific Circuit design for operating in pressure control mode Operating a pump with a variable speed drive in pressure control mode requires the hydraulic circuit to be designed taking the following points into account. A pressure relief valve is still needed as a safety device. A bypass line must be included in the hydraulic circuit. It will provide the necessary cooling flow for the pump and help in stabilizing the fluid viscosity in order to achieve a stable pressure regulation. The bypass line can be activated by an on/off directional control valve when the system is above a certain pressure value and below a certain speed value. U P X Example of bypass line circuitry : The size of the orifice is depending on the maximum pressure value to be regulated, and the pump type. FCU Determination of the necessary bypass flow: Q Bypass@p = q vs + Q yst q vs : internal flow loss of the pump at the operating pressure p. Q yst : flow amount that is necessary to compensate the leakages of the actuators and valves, and to compress the oil volume. Internal leakage q Vs [l/min] Internal leakage (Typical) ct 1 ct Example: Pump T7B E9 operating at p = 24 bar IO VG32 mineral oil at approx 45 C Vi T7B E9 = 28 cm 3 /rev Estimation based on the circuit design, Q yst = 1 lpm Value Read from the T7B technical data page, q vs = 3 lpm Q Bypass@p = = 4 lpm Estimation of the orifice diameter to get at least 4 lpm at 24 bar a,7 mm (Values measured with mineral oil at a viscosity of 4 ct and 5 C) 39 Parker Hannifin Manufacturing France A

40 Catalogue HY29-11/UK Circuit Design Decompression : The T7 pumps for variable speed drives may be operated in a 2 quadrant mode: - Pump mode : flow is going from the "" to the "P" port - Motor mode : flow is going from the "P" to the "" port The Rotation way described in the pump model description is corresponding to the pump mode. Never install a check valve on the "P" discharge line of the pump when a reverse rotation way is enabled. pecial care has to be taken for the transition between cycle steps, in particular for the switch of the directional control valves. When operating the pump in pressure control mode, this is of the utmost importance. In this case, the pressure set value must be ramped down before switching to flow control mode and then energizing the directional control valve. The technology of the T7 pumps for variable speed drives is allowing a quick natural decompression of the pressure line without the need to reverse the rotation way of the E motor. Only very fast cycling machines may require to reverse the rotation way in order to decompress the presure line in a very short time. In such a case, care must be taken that the pressure line remains positive at all time as to avoid any cavitation noise and wear to occur. Negative speed values in the range of -5 rpm could be considered. Dynamic characteristics The dynamic characteristic of a hydraulic system is depending on many parameters, the hydraulic pump being only one of these. This is why it is not possible in a pump catalogue to indicate precise dynamic values. We would like however to point out the following : - The moment of inertia of the pump is mentioned on its data page of this catalogue. - In flow control mode, the pump response time will be depending on the dynamic performances of the electric motor used, its drive unit and the oil circuitry. Flow response times in the same range or shorter than variable displacement load sensing pumps are achievable. - When assembled to servo motors, fast drives and fast sensors, our pumps are allowing a closed loop pressure control suitable for many applications.

41 Catalogue HY29-11/UK Circuit Design Pump installation Pump mounting The environment of the pump has to be taken into consideration as to avoid noise reflection, pollution and shocks. These pumps are designed to operate in any position. Always prefer an installation with a flooded inlet or with the pump inside the oil tank. The installation of the pump on the top of the tank should be restricted to the operation in Flow Mode with moderate dynamic requirements. In such a case the inlet pipe of the pump must be sized according to the max discharge flow in order to keep the inlet velocity below 1,5 m/s. d [mm] Inner diameter of the inlet pipe or hose v [m/s] Average velocity d = Q [L/min] Inlet flow 4 Q p v Q v haft and coupling data - haft loads : These products are primarily designed for coaxial drives which do not impose axial or side loading on the shaft. The max. permissible load values are indicated on the pump technical data page. Contact Parker for specific applications. - Keyed shafts : Parker supplies its keyed shaft pumps with high strength heat-treated keys. Therefore, when installing or replacing these pumps, the heat-treated keys must be used in order to ensure maximum life in the application. If the key is replaced, it must be a heat-treated key between 27 and 34 R.C. hardness. The corners of the keys must be chamfered by,76 mm to 1,2 mm (.3 to.4) at 45 to clear the radii in the key way. The alignment of the keyed shafts must be within the tolerances given for the splined shafts here below. - Couplings and female splines : The coupling must be selected to minimize the load on the shaft (weight, misalignment). The female spline must be made to conform to the Class 1 fit as described in AE-J498b (1971). This is described as a Flat Root ide Fit. The mating female spline should be free to float and find its own center. If both members are rigidly supported, they must be aligned within,15 TIR (.6 TIR) or less to reduce fretting. The angular alignment of two splines axes must be less than ±,5 per 25,4 radius (±.2 per 1 radius). The coupling must be hardened to a hardness between 29 and 45 HRC. The coupling spline must be lubricated with a lithium molydisulfide grease, disulfide of molybdenum or a similar lubricant. Fluid connections Keep a maximum distance between the suction pipe and the return lines in the tank. A bevel of min 45 on suction and return lines is recommended in order to lower the fluid velocity. Fluid lines must be adequate size and strength to assure free flow through the pump. An undersized inlet pipe will prevent the pump from operating properly at full rated speed. An undersized outlet line will cause back pressure, heat generation and noise increase. If the pump is inside the tank, use a short inlet pipe. Flexible hose lines are recommended. If rigid piping is used, the workmanship must be accurate to eliminate strain on the pump ports or to the fluid connections. harp bends in the lines must be eliminated wherever possible. All system piping must be cleaned and flushed before installing the pump. 41 Parker Hannifin Manufacturing France A
