A kind of energy-efficient double-output portable hydraulic power station
Technical field
The present invention relates to a kind of hydraulic power unit, especially relate to a kind of energy-saving double loop output portable hydraulic power station.
Background technique
Hydraulic power station is the power source of hand-held hydraulic instrument, and wherein the most frequently used Hydraulic power tools is broken instrument such as Hydraulic pick, and hydraulic power station drives the fragmentation work that Hydraulic pick is finished road pavement.The fluid pressure drive device of the broken instrument of the hand-held hydraulic of domestic present use is from external import mostly.U.S. Stanley company proposed model commonly used is a HP08 type hydraulic power station, and this hydraulic power station drives oil hydraulic pump by 9 horsepowers petrol engine, and output flow is 19L/min, and delivery pressure is 140Bar.Fuel tank, oil pump and wind-cooling heat dissipating apparatus structure layout are reasonable inadequately; the design of intake grill baffle arrangement is not good enough; greatly influenced air output, caused radiating effect poor, continuous operation was above 3 hours; hydraulic oil temperature just can reach more than 70 ℃; must shut down this moment, treats that the hydraulic oil temperature prize to just often, just can work on; thereby stream time is short, influences working efficiency.
Chinese patent discloses a kind of portable hydraulic power station No. 200820001084.0, this hydraulic power station comprises base, hydraulic oil container, oil hydraulic pump, wind-cooling heat dissipating device, external frame and petrol engine, described base bottom is provided with two and moves wheel, the base side is by the fixing external frame of screw, the external frame left side handle that is coupling; Described base left end front is fixed with hydraulic oil container, hydraulic oil container rear side welding wind-cooling heat dissipating device, the upper cover plate bottom of hydraulic oil container and wind-cooling heat dissipating device is provided with the control valve piece that filter is housed, oil hydraulic pump is equipped with in described wind-cooling heat dissipating device bottom, oil hydraulic pump connects cancellated intake grill baffle plate, oil hydraulic pump is connected with petrol engine by coupling, drives oil hydraulic pump during engine operation and can drive the interior hydraulic oil periodic duty of hydraulic oil container.This compact equipment moves more convenient; Hydraulic oil container, wind-cooling heat dissipating device layout are more reasonable, and intake grill baffle plate incoming air area is bigger, has strengthened radiating effect, for a long time continuous firing.But still have following defective: (1) has only an output port, can only be with a kind of Hydraulic power tools work at every turn, and efficient is lower; (2) motor does not have the load feedback speed control system, energy consumption height: in general, the operating time of the external pressure oil output in hydraulic power station starting back is less than 50%, though the other times motor is still at high speed operation, but actual is to flog a dead horse, and idle gasoline engine work oil consumption 25% below when the time only needing proper functioning, one side consumes a large amount of energy (consuming more than 35%) more like this; The temperature of hydraulic oil is raise rapidly, quicken it and wear out; (3) hydraulic oil container does not have liquid level to take into account hydraulic oil oil starvation warning device, causes the oil temperature sharply to raise easily and makes system failure; (4) return filter does not have obstruction alarm device, often is difficult for when taking place to stop up finding that also can work on, cause the accident this moment easily; (5) base contacts with ground, does not have vibration damping equipment, and this can make whole system be in the vibrating fatigue state for a long time always, and lifetime of system can shorten greatly because of excessive fatigue; (6) the output hydraulic pressure can not be adjusted according to the required optimum working pressure of Hydraulic power tools, thereby, the not high even damage system with some tool system matching degrees sometimes.
