  • the assembly comprises a retainer means configured movable between a first position suppressing relative movement between the foundation and the base plate for increasing stiffness and/or damping and/or damping of support of the base plate of the pump unit on the foundation, a second position being neutral in influencing to relative movement between the foundation and the base plate.
  • the base plate is supported on the foundation by several vertical legs wherein the resilient support is arranged between the leg and the base plate, and the retainer means are arranged to selectably supress relative movement between the leg and the base plate in the plane of the base plate.
  • the retainer means are provided with a body part, and pusher part adjustably attached to the body part, wherein the relative movement between the leg and the base plate is suppressible by bringing the pusher part against either one of the base plate or the leg while the body part being attached to either one of the base plate or the leg.

  • a pump unit comprising an assembly for attenuation of vibration according to the invention.
  • base plate means a generally planar structure on which a centrifugal pump and its motor are assembled.
  • the base plate may be a framework which is constructed of multiple beams arranged to form the planar structure.
  • the pump unit comprises a resilient support 24 in the base plate 20, such that the pump unit 10 is supported resiliently on the foundation 22.
  • the resilient support 24 is resilient several directions.
  • the resilient support may comprise one of, or a combination of a spring, resilient block, such as a rubber block, vibration damper, such as viscose damper, or alike.
  • the resilient support is a compression spring 25.
  • the resilient support has a main compression direction which is bearing the load caused by the mass of the pump unit 10. The main compression direction is therefore substantially vertical direction transverse to the plane or the base plate 20.
  • the pump 14 is connected to the pipework aggregate without any bellows, that is using simple flange joint 14.2 directly to respective feed pipe 14.1 and return pipe 14.3. Such a flange joint may be considered as a rigid coupling. At least the flange joint 14.2. is considerably stiffer than the resilient support 24.
  • FIG. 2 shows a side view of a pump unit 10 according to an embodiment of the invention.
  • FIG. 3 shows a left-side end view of the Figure 2 .
  • FIG. 5 shows a sectional view V-V marked in the figure 3 which is in turn shown in the Figure 5 .
  • the pump unit 10 comprises an assembly 26 for attenuation of vibration of a pump unit to selectably effect on the resilient support 24 in the base plate 20 and vibration characteristics of the pump unit 10.
  • the assembly 26 comprises adjustable retainer means 28 for increasing stiffness and/or damping of support of the base plate of the pump unit on the foundation.
  • the retainer means 28 can be selectably activated for effecting on the stiffness and/or damping of support of the base plate and deactivated. In addition to mere on-off action of being activate or passive, the stiffness is adjustable by adjusting the force by which the retainer means 28 effects.
  • FIG. 7 there is shown an enlarged view A in the figure 6 , which shows one of the resilient supports 24 in connection with which two retainer means 28 are arranged.
  • the retainer means 28 are arranged as pairs in which the retainer means 28.1'-28.1" effect in opposite directions to each other.
  • the first pair of retainer means 28.1'-28.1" is arranged to effect in the direction of the selected direction, and a second pair of retainer means 28.3' - 28.3" is arranged to effect in the direction perpendicularly to the selected direction.
  • the retainer means 28 are provided with a body part 32, and a pusher part 34 adjustably attached to the body part 32, wherein the relative movement between the leg 30 and the base plate 20 is suppressible by bringing the pusher part 34 against either one of the base plate 20 or the leg 32 while the body part 32 being attached to either one of the base plate 20 or the leg 32.
  • the pusher part 34 is brought against the other one of the base plate 20 or the leg 32.
  • the body part 32 of the retainer means 28 is attached by screws to the base plate 20 and the pusher part 34 is brought against a surface of the leg 32.
  • the pusher part is configured to adjustably push against the leg.
  • the pusher part is configured to be selectably activated, by bring it against the leg 32, and deactivated by detaching the pusher part 34 from the leg 32, and when activated the pressing force of the pusher part is adjustable.
  • the pusher part 34 comprises a screw bar and the body part comprises a threaded hole 36 to which the screw bar is attached so as to provide adjustable longitudinal movement of the screw bar by rotation thereof.
  • the pusher part 34 is provided with a resilient head 38 at an end of the screw bar 34.
  • the surface in the leg, against which the pushed part 34 is pushing can be provided with an optional, additional counter part 40, by means of the characteristics of the support can be further controlled.
  • the counter part 40 may be for a resilient block or a plate.
  • the counter part 40 may be arranged in connection with one or more, or all of the pusher parts 34.
  • stiffness and/or damping of support of the base plate of the pump unit on the foundation is increased, such that stiffness and/or damping of support of the pump unit 10 on the foundation is ruled in addition to the resilient support, by means of the pusher part 34, as is depicted in the figure 7 .
  • the retainer means 28 it is possible to minimize excessive vibration of the pump unit 10 induced by excitations from the pipework.
  • the resilient support results in advanced operation during the start-up stage compensating heat expansion of the pipework aggregate, while during the steady state operation, when the operational temperature has been reached, increased stiffness and/or damping is brought by the pusher part minimizing excessive vibration of the pump unit 10.
  • the method may include a step of setting a target operational temperature to the process fluid and/or the pipework aggregate, and acquiring a measured temperature of the process fluid and/or the pipework aggregate, and in case the measured temperature is lower than the target operational temperature the pipework aggregate is in a transient state operation, and in case the measured temperature is equal to or higher than the target operational temperature, the pipework aggregate is in a steady state operation.
  • Each one of the retainer means 28 effects in one direction in the plane of the base plate 20.
  • the assembly comprises a pole 42 which is attached to the foundation 20 similarly to the legs 30 of the pump unit 10. In practise the surface at the end of the pole 42 in the figure 9 is attached to the foundation.
  • the pole extends upwardly from the foundation into the plane of the base plate 20 between its structural beams.
  • the body part 48 is provided with a pusher screw 50 by means of which the position of the wedge part 46 can be changed. Movement of the wedge part 46 tightens the wedge-shaped space between the support block 44 and the body part 48, and this way effects on the stiffness and/or damping of support of the base plate 20.
  • the contact may be arranged as a gliding contact by arranging a suitable glide part to either one, or both of the surface.
  • FIG 11 discloses a view of a pump unit 10 from beneath the pump unit 10 according to another embodiment of the invention.
  • the pump unit 10 comprises an alternative assembly 26 for attenuation of vibration of a pump unit to selectably effect on the resilient support 24 in the base plate 20 and vibration characteristics of the pump unit 10.
  • the assembly 26 comprises four retainer means 28 for increasing stiffness and/or damping of support of the base plate of the pump unit on the foundation.
  • vibration of the pump unit is analysed during the transient state operation and if at least one direction of vibration, which has vibration amplitude greater than a pre-set limit value of the amplitude, is determined, stiffness and/or damping of the base plate of the pump unit is increased in at least the determined direction of vibration.
  • stiffness and/or damping of support of the base plate of the pump unit on the foundation is increased by arranging a mechanical retainer means to suppress relative movement between the base plate and the foundation in the determined direction of vibration.
  • Change of the fluid characteristics is change of temperature and operation is steady state operation when the temperature has reached a predetermined temperature level.
