Can realize bifrequency open hydraulic pressure vibration system

The utility model discloses a can realize bifrequency open hydraulic pressure vibration system, including oil tank, automatically controlled confluence pump, vibration switching -over valve, motor, filter, the oil tank is connected to the S mouth of automatically controlled confluence pump, and the oil -out P1 of automatically controlled confluence pump connects the entry P2 of vibration switching -over valve, and vibration switching -over valve is connected with the motor, and the oil return opening T of vibration switching -over valve is connected with the oil tank. The utility model discloses in automatically controlled confluence pump can press needs repositions of redundant personnel or confluence, realize the output flow rate of two differences, in the vibrated roller field, can realize the dual -frenquency vibration. This system can replace the closed hydraulic pressure vibration system of road roller adoption both at home and abroad at present, forms all components of system and can all realize the production domesticization to the cycle that does not receive the import piece restricts, simultaneously can the greatly reduced cost. This system also can use the various equipment at two output speed of needs.
