Zusammenfassung: | The utility model relates to a double-valve-set power system which is applied to the logging process of an oil survey. The double-valve-set power system resolves the technical problem that the existing hydraulic power system is difficult to be applied to small sites. The system comprises a double-acting cylinder, a first chamber and a second chamber, wherein the first camber and the second chamber are installed inside the double-acting cylinder. The system further comprises a pump, a safety valve, a first one-way valve, and a first reversing valve, wherein the pump, the safety valve, the first one-way valve, the first reversing valve and the first chamber are sequentially communicated. The system also comprises an outlet end of a second one-way valve, a second reversing valve and a second chamber, wherein the outlet of the second one-way valve, the second reversing valve and the second chamber are sequentially communicated. The inlet end of the second one-way valve is arranged between the first one-way valve |
