Abstract
The utility model relates to an energy saving hydraulic power source. The utility model is that an electric motor, a hydraulic pump, and other components such as an oil storage tank, a controller, a fan, a cooler, etc. are integrated. The ac electric motor driven by a frequency changing controller directly drives a dosing pump, and the variation of the hydraulic pump can be realized. Compared with an existing separating hydraulic power source, the utility model uses integration, low noise, energy saving, and digitization as the technological progresses, and the utility model has the advantages of hydraulic power source structure simplification, low vibration, low noise, and good energy saving effect. The moving components in the hydraulic power source are in self lubrication, and no leakage for the outside exists, and the digital variable control of the hydraulic power source can be realized.
Description
The utility model relates to a kind of hydraulic power that pressure oil is provided for hydraulic motor (motor, oil cylinder).
Characteristics such as with pressure oil be that the hydraulic motor that drives is little with volume, stable drive, transferring power are big, easy to control are used widely in fields such as process equipment, engineering machinery, military equipments.The drive part of traditional hydraulic system adopts the standard base parts to combine, promptly by motor, oil hydraulic pump, fuel reserve tank and control unit through simple combination, constitute the hydraulic power that satisfies particular requirement.This hydraulic power that constitutes through simple combination can satisfy the requirement of application to the hydraulic power function aspects basically, but on performance, then there is bigger defective, mainly show following five aspects: first volume weight is big, the hydraulic power volume that combines with standardized element is big, makes the physical dimension of final products too huge; It two is that transmission is not steady, because the connection of separation criterion part exists certain elasticity and gap, makes transmission not steady, is easy to generate vibration and noise; It three is energy consumption height, adopt standard motor to link to each other with metering pump or variable displacement pump, corresponding adjusting input power when hydraulic power is difficult in work loads and changes, the result causes system effectiveness decline, hydraulic system temperature rise aggravation or power of motor factor are descended, produce meaningless energy consumption; It four is that fault hidden danger is many, and the used component of hydraulic power are many, has increased the link that produces fault; It five is that control is difficult, is the control that realizes hydraulic motor pressure and flow, and conventional hydraulic power need adopt variable displacement pump and variable controlling device, is difficult to realize Digital Control.The above-mentioned defective in conventional hydraulic source makes hydraulic power itself and relevant final products answer technology content few and lack competitiveness.
The purpose of this utility model is to propose to solve the existing problem of present hydraulic power, reduce the hydraulic power volume and weight, simplify general arrangement and component number, improved controllability (realization Digital Control) to the hydraulic motor flow, reduce energy consumption, solve transmission not steadily and the many defectives of fault, with highly integrated, low noise, energy-conservation and be digitized as technological progress, the quality of raising hydraulic power product and relevant final products.
Basic design of the present utility model is with motor, oil hydraulic pump and other parts, become one as parts such as fuel reserve tank, controller, fan and coolers, hydraulic power can directly drive metering pump by the frequency-variable controller drive electric motor, regulate motor speed by digital control approach, realize the hydraulic power variable, also can directly drive variable displacement pump, realize the hydraulic power variable in the hydraulic control mode by deciding the rotating speed motor.
Compare with existing parting liquid potential source, the utility model hydraulic power mainly contains the outstanding advantage of following several respects: the one, simplify the structure, integrated by height to used unit, simplified hydraulic power general arrangement, no connection pipe fitting, used component number reduces 40%, and hydraulic power overall geometry size reduces half, and quality reduces more than 60%; The 2nd, the system vibration noise is little, because of having cancelled connecting link, has reduced the vibration and the noise that cause because of the elasticity in the drive path, gap and decentraction; The 3rd, good energy-conserving effect, because adopt frequency control motor directly to drive fixed displacement motor, the hydraulic power system can change power input to a machine according to the variation of work loads or artificial requirement better, reduces unnecessary energy consumption.The 4th, moving parts is selflubricating in the hydraulic power, does not externally have and leaks, and system can reach thermal equilibrium fast; The 5th, easy to control, with frequency control way control motor driving fixed displacement motor, both simplified pump structure, improved digital control ability and precision again to hydraulic motor pressure and flow.
Accompanying drawing 1 is the utility model sectional view.
Accompanying drawing 2 is hydraulic pressure graphical diagrams of the present utility model.
Below in conjunction with accompanying drawing the utility model is elaborated.As shown in Figure 1, the utility model by Wechselstrommotor 8, vane pump 2, frequency-variable controller 12, axle 7, the pump housing connect dish 3, a left side is joined elements such as oily end cap 1, right end cap 9, pressure transducer 13, seal ring 4, casing (fuel reserve tank of holding concurrently) 6, cooling fan 10, radiator 11, oil suction filter cleaner 5 and is formed.Vane pump 2 connects dish 3 by the pump housing and motor 8 is integrated in the housing 6 of double as fuel reserve tank, vane pump 2 is directly installed on AC motor 8 output shafts one end, Wechselstrommotor 8 is driven by frequency-variable controller 12, realizes the requirement of hydraulic power variable by the rotating speed that changes motor 8.Cooling fan 10 and radiator 11 are installed in the outside of fuel reserve tank housing 6, and cooling fan is directly installed on the outside output axle head of motor.Outside oil return and the inner oil return spill port of flowing through flows to radiator 11, gets back in the hydraulic power casing 6 of double as fuel reserve tank after the cooling of liquid stream.Rotating part adopts high pressure sealing ring 4 to seal between vane pump 2 and the motor 8, and a small amount of internal leakage can be lubricated bearing.The trigger switch signal was in time controlled the rotating speed of 12 pairs of motors 8 of frequency-variable controller when pressure transducer 13 can reach qualification pressure in system, realized overload protection.5 pairs of filter cleaners that are installed in filler opening enter circuit liquid stream and filter, and guarantee liquid stream cleaning.
The used oil hydraulic pump of the utility model can be vane pump, gear pump or plunger pump.Vane pump, gear pump and plunger pump with metered dose are the hydraulic power driven pump, and system will control motor speed by the digital frequency conversion mode, thereby realize flow control; If adopt variable displacement pump, then motor can be to decide the rotating speed motor, realizes the hydraulic power variable by hydraulic control.
