Background
As is well known, the submersible full-through-flow pump is one of the traditional submersible axial-flow pumps, the submersible axial-flow pump is one of the large drainage and irrigation devices used in China at present, the motor structure of the submersible axial-flow pump with the built-in impeller is of a wet structure, a motor stator is arranged in a pump body cavity, a water pump impeller is inlaid in a motor rotor cavity and forms a whole with a rotor, and the motor rotor rotates to drive the internal impeller to rotate in the running process of the device, so that the drainage effect is achieved. The Chinese patent No. 2013104233646 discloses a submerged axial flow pump with built-in impeller. Comprises a water sucking chamber, an impeller hub and a water outlet chamber which are coaxially communicated; the motor also comprises a motor rotor and a motor stator; the motor rotor is fixedly arranged on the outer circumference of the impeller shell, one ends of more than three blades are uniformly distributed on the inner circumference of the impeller shell, the other ends of more than three blades are respectively connected with the impeller hub to form an impeller, and the impeller is positioned in the middle of the motor rotor, so that the motor rotor and the impeller form a whole; the motor stator is sleeved outside the motor rotor to form a water-filled submersible motor, so that the axial length of the submersible axial flow pump is greatly shortened, and the structure is compact; on the other hand, the strength and rigidity requirements on the rotating shaft are reduced; the submersible motor is arranged outside the runner, pumping water flow of the submersible pump is not influenced, and efficiency of the submersible pump and safety and reliability of the motor are improved. The bearing chamber is sealed by adopting a cartridge type mechanical seal, so that the requirement on installation precision is reduced, and the floatability is good.
However, the existing equipment cannot monitor vibration of a water pump motor and a pump shaft in the running process, and cannot monitor leakage of a sealed bearing chamber. If the motor is disturbed by external factors or the vibration of the water pump is increased along with the time, the rotor is affected by the vibration to cause unbalance in operation, and the vibration of the fixed pump shaft of the water pump is increased, so that the service life of the equipment is reduced, even the internal bearing is damaged or directly broken, the balance degree of the motor rotor is reduced to cause the occurrence of a canteen phenomenon of the motor, and the motor is burnt. Or the sealing performance of the bearing chamber is reduced due to overlarge vibration, so that external media enter the bearing chamber to damage parts such as a bearing and the like.
Moreover, in the bearing chamber of the inner cavity of the motor rotor, the lubrication grease or the lubricating oil is generally smeared for bearing lubrication, which is unreliable in long term, because the smearing of the lubricating grease or the lubricating oil can help to increase the lubrication effect of the bearing in a short time, but the lubrication effect can be gradually reduced or even lost after long-time operation, and once the bearing chamber has leakage condition of external medium due to sealing problem, the lubrication effect of the bearing can be reduced linearly and rusted, and bearing breakage condition can occur, thereby leading to equipment damage.
The rotor bearing chamber should be the space that the seal is good under the prior art, as described above, if outside liquid medium or impurity get into the bearing chamber because of sealed problem under the prior art, then can't monitor and judge, can't timely make effective pair to also can lead to bearing lubrication degree straight line reduction and increase corrosion, lead to bearing or other parts damage.
