Description

Technical Field

[0001] The utility model relates to the technical field of motor jacking oil systems, in particular to a perspective structure of a motor high-pressure jacking oil system. Background Art

[0002] Due to the weight of the rotor of a high-power high-voltage motor, when not in operation, the rotor will contact the bearing bush. If it is started directly, the bearing bush will be worn. Before starting the motor, the rotor needs to be lifted by the high-pressure jacking oil system before starting the motor.

[0003] The jacking oil system needs to be filled with oil for the first time before it is put into operation. The jacking oil system can only be put into operation after the oil filter is filled with oil. In order to determine whether the oil filter is full of oil, a perspective mirror is generally installed on the oil filter to observe whether the inside is full of oil. However, the pressure of the jacking oil system is high, and the pressure of each oil filling will be different. It is difficult to configure a perspective mirror with the corresponding pressure level on the market. If a perspective mirror with an incompatible level is installed, the perspective mirror will rupture and cause injuries to the inspector. If a perspective mirror is not configured, it is impossible to determine whether the oil filter is full of oil during the first oil filling. Utility Model Content

[0004] The technical problem to be solved by the utility model is that the existing top shaft oil system is difficult to match and install a suitable perspective mirror.

[0005] In order to solve the above technical problems, the technical solution of the utility model is to provide a perspective structure of a motor high-pressure top shaft oil system, including an oil filling pipe, an oil filter, an oil outlet pipe and an oil tank, the oil filling pipe is connected to the oil filter inlet, the oil filter outlet is connected to the oil tank through the oil outlet pipe, and the oil outlet pipe is provided with a perforated box and a perspective pipe, the perforated box is close to the oil filter, and the perspective pipe is close to the oil tank.

[0006] Optionally, a perspective mirror is provided on the perspective tube, and a perforated plate is provided in the perforated plate box.

[0007] Optionally, a normally closed valve is provided between the orifice box and the oil filter.

[0008] In summary, the present invention sets the perspective mirror on the oil outlet pipeline and sets a perforated box for reducing the pressure, so as to avoid the perspective mirror from breaking due to excessive oil pressure and reduce the risk of injury to workers.

[0011] The following combination Figure 1 The utility model is described in further detail.

[0012] The utility model discloses a perspective structure of a motor high-pressure top shaft oil system, referring to Figure 1 , including an oil filling pipe 1, an oil filter 2, an oil outlet pipe 6 and an oil tank 5. The oil filling pipe 1 is connected to the inlet of the oil filter 2, and the outlet of the oil filter 2 is connected to the oil tank 5 through the oil outlet pipe 6. An orifice box 3 and a perspective tube 4 are provided on the oil outlet pipe 6. The orifice box 3 is close to the oil filter 2, and the perspective tube 4 is close to the oil tank 5. A perspective mirror 7 is provided on the perspective tube 4. An orifice plate is provided in the orifice box 3, and a normally closed valve 8 is provided between the orifice box 3 and the oil filter 2.

[0013] In the utility model, the perspective mirror 7 is not necessary to match the top shaft oil system, and a perspective mirror 7 with a smaller pressure bearing can be used, which can be selected according to the pressure reduction capacity of the orifice box 3. When the oil filter 2 is filled with oil for the first time, the normally closed valve 8 is opened, and the high-pressure top shaft oil enters the oil filter 2 from the oil filling pipeline 1. After the oil filter 2 is full, the high-pressure top shaft oil flows through the normally closed valve 8 at the outlet of the oil filter 2, and then flows into the orifice box 3 from the normally closed valve 8. After the orifice box 3 is decompressed, it passes through the perspective pipe 4 and flows back to the oil tank. If the oil flow can be seen from the perspective mirror 7, it means that the oil filter 2 is full of oil, the air in the pipeline has been completely discharged, and the normally closed valve 8 is closed, and the top shaft oil system can be put into use.

[0014] The utility model arranges a orifice box 3 in front of the perspective mirror 7 to limit flow and reduce pressure. The pressure at the rear end of the orifice box 3 has been reduced to the operating pressure of the perspective mirror 7. The perspective mirror 7 will not be broken due to excessive pressure in the top shaft oil system, thereby reducing the risk of injury to inspectors.

[0015] It should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
