Transformer Hydraulic Suspension Oil Pump
The hydraulic suspension oil pump solves the problem of unstable operation of the existing oil pump. The hydraulic suspension oil pump comprises a casing, wherein the casing is provided with a rotating shaft and an impeller, and the impeller is fixedly connected to the connecting end of the rotating shaft, the rotating shaft has a through axial passage therein, the impeller has a circulation passage, and the oil inlet passage passes through the axial passage and The circulation passage is connected with the oil outlet, and the housing has a mounting seat, and the first stabilizer is fixed on the mounting seat for positioning the impeller, and the first lubricating passage and the impeller have a first lubrication passage, and the impeller and the mounting seat There is a balance chamber, and the balance chamber communicates with the inner cavity of the casing through the first lubrication passage. The center of the impeller has a pressure relief hole for communicating the balance chamber with the inlet end of the flow passage, and the balance chamber has the balance chamber and the outlet. Balance hole with oil ports connected. The hydraulic suspension oil pump has the advantages of stable operation and long service life.
