Description

Hydraulic power pack
Technical field
The application requires the preference of the U. S. application sequence number 61/229,298 of proposition on July 29th, 2009, and its content is incorporated at this by reference.
Background technique
Being used to control the hydraulic power pack that fluid distributes knows with other device.
Disclosure of the Invention
The objective of the invention is to produce with thoroughly improving control, increase mechanical life, use the design simplified, cutting down the consumption of energy, reduce the hydraulic power pack that cooling required and reduced noise level.
Hydraulic power pack of the present invention is by 1) hydraulic fluid is passed to the hydraulic pressure manifold, 2 in correct zone) hold the hydraulic pressure storage, 3 of hydraulic fluid) oil hydraulic pump, 4) DC servomotor, 5) directional control valve, 6) cooling system and 7) integrated filter housing, 8) electronic device-the be used to motor controller of controlling the DC servomotor forms.
Hydraulic power pack (HPM) running is with the oil hydraulic cylinder of supplying hydraulic fluid with the various configurations that turn round.The DC servomotor is directly connected to oil hydraulic pump through hydraulic pressure manifold.When motor rotated, pump was sent to directional control valve through manifold with hydraulic fluid.HPM sends signal so that circulate to the either side of oil hydraulic cylinder to directional control valve.HPM together with sensor (example: the flowmeter in the fluid line, the linear transducer that is associated with oil hydraulic cylinder, or the like) with the piston speed in the accurate control oil hydraulic cylinder so than hydraulic fluid is provided.Also can resist opposite power and make the position of hydraulic cylinder piston keep fixing.This causes accurate flow rate or constant dynamic pressure and static pressure.
System of the present invention has many advantages, such as through utilizing DC servomotor and motor controller to strengthen control consumingly.Another result is the system mechanics life-span of improving, and promptly in the time need not flowing, all parts stop to move, and this can cause less wearing and tearing.
The present invention has reduced the hydraulic pressure cooling requirement through in the time need not flowing, allowing to stop to flow.
Compare with traditional AC power supplies group system, the present invention causes the Machine Design simplified.The dynamic response of HPM has been eliminated the demand of electric storage means.
HPM control allows with the full moment of torsion output of zero velocity.This system that makes makes almost response (though constitute pressure, not having delay) at once to flow demand.
The dynamic response of HPM allows to make hydraulic power pack to produce than the more compensation of constant compression force and/or mobile system change of traditional AC technology.HPM control allows to change pressure and has no mechanical adjustment (pressure-compensated pump, dump valve or the like) with flowing.HPM controls motor torsional moment, speed and position, and common AC power supplies group control rate only, and this causes the control that improves.
Noise level is lower than traditional AC power supplies group design.Design and control help to provide the energy consumption of reduction.System only utilizes energy as required.Closed-loop path FLOW CONTROL based on linear transducer provides equal control with lower cost point.Algorithm will be effective to any oil hydraulic pump.When the new pressure of needs and/or when mobile, only need the replacement pump.
Find out that from the description of carrying out below in conjunction with accompanying drawing of the present invention these will manifest with other purpose and advantage more fully, wherein in whole some width of cloth figure, similar fixed reference feature refers to identical or similar parts.
The accompanying drawing summary
Fig. 1 has shown the front view of HPM of the present invention.
Fig. 2 has shown the rear view of HPM of the present invention.
Fig. 3 has shown the figure that removes storage of the pump of showing HPM of the present invention.

The invention preferred forms
Hydraulic power pack 10 of the present invention is made up of following: electronic device-be used to the control motor controller 28 of DC servomotor 20 integrated filter housing 26 and 8 cooling system 24,7 directional control valve 22,6 DC servomotor 20,5 oil hydraulic pump 18, the 4 hydraulic pressure storage 14,3 that the hydraulic pressure manifold 12,2 that 1) hydraulic fluid is passed to correct zone) holds hydraulic fluid 16)))))).
Hydraulic power pack (HPM) 10 runnings are with the oil hydraulic cylinder 30 of supplying hydraulic fluid 16 with the various configurations that turn round.DC servomotor 20 is directly connected to oil hydraulic pump 18 through hydraulic pressure manifold 12.When motor 20 rotations, pump 18 is sent to directional control valve 22 through manifold 12 with hydraulic fluid 16.HPM 10 sends signal so that circulate to the either side of oil hydraulic cylinder 30 to directional control valve 22.HPM 10 together with sensor 32 (example: the flowmeter in the fluid line, the linear transducer 34 that is connected with oil hydraulic cylinder, or the like) with the piston speed in the accurate control oil hydraulic cylinder 30 so than hydraulic fluid 16 is provided.HPM 10 also can resist opposite power together with sensor 32 and make the position of piston of oil hydraulic cylinder 30 keep fixing.This causes accurate flow rate or constant dynamic pressure and static pressure.
Think and to carry out variations and modifications and not depart from the spirit and scope of the present invention that limit following claim hydraulic power pack.
