Problems solved by technology

[0003] The pressure of the existing hydraulic power station is 14MPa, the flow range is 30-40L / min, and the weight of the whole machine is more than 150kg. Due to the use of traditional materials, the integration of parts and components is low, the weight of the whole machine is large, it is inconvenient to carry, and it cannot be used for long-term heavy-duty work. In addition, the output flow of the existing models is too small, which cannot meet the needs of large input flow of some hydraulic tools, and the types of suitable hydraulic tools are limited.

[0004] At the same time, the existing hydraulic power station models cannot cool the high-temperature hydraulic oil for a long time, that is, it is not enough to reduce and maintain the oil temperature of the high-temperature hydraulic oil below the desired 80°C, and the oil temperature can exceed 120°C when working for a long time , when the oil temperature is above 100°C, the executive components connected to the hydraulic oil circuit, such as hydraulic shears, demolition tools, road excavation tools, hydraulic picks, wire hydraulic crimping pliers, hydraulic tree trimmers, etc., often Unable to work, and even cause safety accidents, because the higher the temperature of the hydraulic oil, the greater the pressure of the hydraulic oil, which may cause the pipeline to burst, or cause the executive components to collapse

If the hydraulic cooling capacity is increased on the basis of the original model, the engine power needs to be increased, which will inevitably lead to a substantial increase in the weight of the whole machine

[0005] At the same time, the output flow of the existing models is relatively small, which cannot meet the needs of large input flow of some hydraulic tools, and the types of suitable hydraulic tools are limited.
