Abstract
The invention provides a power source applicable to an ultrahigh-pressure liquid system. According to certain hydraulic systems, the force required by a unit area is quite large, so that the requirement for liquid pressure is quite high, and ordinary power sources cannot meet the requirement. A traditional ultrahigh-pressure liquid generation method is achieved in the mode that a small-section high-pressure cylinder is pushed by a large-section low-pressure cylinder according to the Boyle law p1V1=p2V2, and accordingly the overall size of equipment is large, the fault rate is large, and the liquid in the ultrahigh-pressure system is polluted once hydraulic oil leaks. According to a device used for generating ultrahigh pressure through direct mechanical driving, no hydraulic oil is needed; and by the adoption of the device, the equipment size can be reduced and the fault rate can be decreased to the greatest extent, and the liquid in the ultrahigh-pressure system is prevented from being polluted. The power source device of the ultrahigh-pressure liquid systems is simple in structure, high in practicability and high in application and popularization value.
