Energy-efficient double-output portable hydraulic power station

Abstract

An energy-efficient double-output portable hydraulic power station comprises a base, a hydraulic control valve seat assembly, an air-cooling heat dissipation system assembly and a gasoline engine assembly. The hydraulic control valve seat assembly comprises a hydraulic valve seat provided with a high pressure oil inlet and a hydraulic oil reflux inlet. Both sides of the hydraulic valve seat are respectively provided with a first high pressure oil output connector, a second high pressure oil output connector, a first hydraulic oil return connector and a second hydraulic oil return connector. The upper part of the hydraulic valve seat is provided with a relief valve, a pressure gauge and a manually rotating switch valve. The gasoline engine assembly comprises a gasoline engine and a hydraulic control cylinder. The gasoline engine is provided with a throttle control lever and the hydraulic control cylinder is provided with a push lever. An outlet oil filter is installed at an oil outlet on the lower part of an oil tank of a hydraulic oil tank assembly and a level gauge is installed at one side of the oil tank. The bottom inside the oil tank is provided with an oil starvation alarm and the upper part of the oil tank is provided with a hydraulic oil return filter and a clogging alarm device. The hydraulic power station is used as a power source of handheld hydraulic tools and features low energy consumption, reliable working and long service life.

Description

technical field [0001] The invention relates to a hydraulic power device, in particular to an energy-saving double-circuit output portable hydraulic power station. Background technique [0002] The hydraulic power station is the power source of the hand-held hydraulic tools. The most commonly used hydraulic tools are crushing tools such as hydraulic picks. The hydraulic power station drives the hydraulic picks to complete the crushing work on the road surface. Most of the hydraulic drive devices of the hand-held hydraulic breaking tools currently used in China are imported from abroad. The commonly used and recommended model of Stanley in the United States is the HP08 hydraulic power station, which is driven by a 9-horsepower gasoline engine with a hydraulic pump, the output flow is 19L / min, and the output pressure is 140Bar. The structural layout of the oil tank, oil pump and air-cooled heat dissipation device is not reasonable enough, and the structural design of the air ...

Problems solved by technology

But there are still the following defects: (1) there is only one output port, and only one hydraulic tool can be used for work at a time, and the efficiency is low; After the station is started, the working time of outputting pressure oil to the outside is less than 50%. Although the engine is still working at high speed at other times, it is actually doing useless work. When the gasoline engine is idling, it only needs 25% of the fuel consumption of normal work. In this way, Consumes a lot of energy (more than 35% more); on the other hand, the temperature of the hydraulic oil rises rapidly, accelerating its aging; (3) The hydraulic oil tank does not have a liquid level gauge and a hydraulic oil shortage alarm device, which may easily cause a sharp rise in oil temperature (4) The oil return filter does not have a clogging alarm device, and it is often difficult to find when it is clogged, and it will continue to work, which is likely to cause accidents at this time; The whole system has been in a state of vibration fatigue for a long time, and the life of the system will be greatly shortened due to excessive fatigue; (6) The output hydraulic pressure cannot be adjusted according to the optimal working pressure required by the hydraulic tool, so sometimes it will match with some tool systems Not high or even damage the system
