Background technique:
Original hydraulic system is according to the performance analysis of equipment, and promptly the Changing Pattern of the speed of each executive component and load requires to calculate, and obtains the parameters such as pressure, flow in the hydraulic system, thereby selects suitable oil hydraulic pump and motor for use.But in the actual job environment, often exist the pump and the rating of electric machine bigger than normal, power of motor is higher; Make essential high pressure of system held for a long time and need pump to continue to keep, and increased the pump wearing and tearing; Valve opens or in pipe-line system, constantly produces vibration when commutating cutting out rapidly, and plunger pump or membrane pump continue to produce situation such as vibration, thereby make system pressure unstable, energy waste, and the damage increase expense of instrument etc. raises the cost.When hydraulic pressure installation breaks down, termination of pumping or when having a power failure runs out of steam the source suddenly and the problem of security incident or a work cycle of completion that can't safety occurs.And because plunger pump or membrane pump continuous firing also can produce the high-decibel noise pollution.
The model utility content:
The purpose of the utility model is exactly the deficiency to existing technology; And a kind of hydraulic pressure low energy consumption system is provided, and it has introduced absorption and the storage device of bladder type hydropneumatic accumulator as excess energy in the hydraulic system, and we still can keep the flow and the pressure of whole hydraulic system under the situation of the power that reduces oil hydraulic pump like this; Can play the effect of environmental protection and energy saving; And it has also relaxed system shock, makes that the working pressure of whole hydraulic system is more stable, has so also just reduced the loss of each hydraulic system element; Reduced cost, the stable of working pressure makes that also operating noise reduces simultaneously.
The technological solution of the utility model is following:
Hydraulic pressure low energy consumption system; Comprise fuel reserve tank, oil hydraulic pump and HYDRAULIC CONTROL SYSTEM valve; The two ends of fuel tank oil outlet tube connect respectively at the oil outlet of fuel reserve tank and the filler opening of oil hydraulic pump; The two ends of oil pump outlet line connect the filler opening at the oil outlet of oil hydraulic pump and HYDRAULIC CONTROL SYSTEM valve respectively, and the oil outlet of HYDRAULIC CONTROL SYSTEM valve connects the return opening of load and fuel reserve tank, and the oil pipe of bladder type hydropneumatic accumulator connects on the flowline of HYDRAULIC CONTROL SYSTEM valve.
Said bladder type hydropneumatic accumulator is made up of tank body, capsule bag that nitrogen is housed, and the capsule bag places tank body, and oil pipe connects tank body.
Said fuel reserve tank is provided with scaffold, and bladder type hydropneumatic accumulator is fixed on the scaffold.
Said scaffold is made up of upper bracket and lower support frame.
Said upper bracket is formed through bolt by the two ends of elastic component.
The core of said lower support frame forms one and places the through hole of bladder type hydropneumatic accumulator bottom
The beneficial effect of the utility model is: it has introduced absorption and the storage device of bladder type hydropneumatic accumulator as excess energy in the hydraulic system; We still can keep the flow and the pressure of whole hydraulic system under the situation of the power that reduces oil hydraulic pump like this; Can play the effect of environmental protection and energy saving; And it has also relaxed system shock, makes that the working pressure of whole hydraulic system is more stable, has so also just reduced the loss of each hydraulic system element; Reduced cost, the stable of working pressure makes that also operating noise reduces simultaneously.

Embodiment:
Embodiment: see shown in Fig. 1 to 3; Hydraulic pressure low energy consumption system; Comprise fuel reserve tank 1, oil hydraulic pump 2 and HYDRAULIC CONTROL SYSTEM valve 5; The two ends of fuel tank oil outlet tube 4 connect the filler opening at the oil outlet of fuel reserve tank 1 and oil hydraulic pump 2 respectively; The two ends of oil pump outlet line 3 connect the filler opening at the oil outlet of oil hydraulic pump 2 and HYDRAULIC CONTROL SYSTEM valve 5 respectively, and the oil outlet of HYDRAULIC CONTROL SYSTEM valve 5 connects the return opening of load 8 and fuel reserve tank 1, and the oil pipe 6 of bladder type hydropneumatic accumulator 7 connects on the flowline of HYDRAULIC CONTROL SYSTEM valve 5.
Said bladder type hydropneumatic accumulator 7 is made up of tank body 71, capsule bag 72 that nitrogen is housed, and capsule bag 72 places tank body 71, and oil pipe 6 connects tank body 71.
Said fuel reserve tank 1 is provided with scaffold 11, and bladder type hydropneumatic accumulator 7 is fixed on the scaffold 11.
Said scaffold 11 is made up of upper bracket 111 and lower support frame 112.
Said upper bracket 111 is formed through bolt by the two ends of elastic component.
The core of said lower support frame 112 forms one and places the through hole of bladder type hydropneumatic accumulator 7 bottoms.
Working principle: the two ends of fuel tank oil outlet tube 4 connect the filler opening at the oil outlet of fuel reserve tank 1 and oil hydraulic pump 2 respectively; The two ends of oil pump outlet line 3 connect the filler opening at the oil outlet of oil hydraulic pump 2 and HYDRAULIC CONTROL SYSTEM valve 5 respectively; The oil outlet of HYDRAULIC CONTROL SYSTEM valve 5 connects the return opening of load 8 and fuel reserve tank 1, and the oil pipe 6 of bladder type hydropneumatic accumulator 7 connects on the flowline of HYDRAULIC CONTROL SYSTEM valve 5.
