Abstract

The invention discloses a hydraulic power source system which comprises a hydraulic system and an auxiliary hydraulic device. The hydraulic system comprises an oil pump, a one-way valve, a first oil filter, a second oil filter, a switch, a scavenge filter and a radiator which are sequentially connected to form a loop; the auxiliary hydraulic device comprises an oil tank and a low-pressure oil transfer pump unit; the oil tank is connected between the oil pump and the radiator of the hydraulic system by a one-way counterbalance valve; and the low-pressure oil transfer pump unit is connected between the first oil filter and the one-way valve of the hydraulic system by an oil supply one-way valve. The invention has the advantages that a switching device in an open-close mode in a common hydraulic power source system is canceled and replaced by a hydraulic auxiliary system, thereby improving the reliability and the safety of the hydraulic power source system and decreasing the production cost. When the hydraulic system works, the auxiliary hydraulic device does not work, and the common characteristics and respective independence of the two systems are fully ensured.

Description

technical field [0001] The invention relates to a hydraulic power source system. Background technique [0002] A large number of hydraulic equipment, devices, and working systems require external hydraulic power sources, such as ground inspection and maintenance of aircraft, deep sea, hydraulic working equipment for underground operations, and so on. Generally speaking, the hydraulic power source has a complete hydraulic circuit and unit, through which the pressure oil source is supplied to the external hydraulic working equipment connected to it, and the return oil is formed by actuation or driving to return the oil to the hydraulic power source equipment. To form a circuit, this circuit system requires the formation of a closed circuit, that is, it is required to keep the amount of oil in the entire circuit of the two devices connected to work without changing, and the oil return pressure in the circuit remains unchanged. This requires at least the oil tank of the hydraul...
