Technical Field
The utility model relates to a pump class product field, concretely relates to submersible sewage pump of area vibration monitoring.
Background
The submersible sewage pump is submerged in water when in normal operation, so the operation state of the electric pump needs to be monitored. Parameters such as water leakage of a motor cavity, water leakage of an oil chamber, winding temperature, bearing temperature and the like are usually monitored, but the monitoring is not enough and cannot reflect the vibration condition when the pump runs. If the field electric pump is unreasonably installed, the coupling surface of the water outlet pipe seat is not sealed during self-coupling installation, the pump runs under a deviated working condition, a bearing is abraded, pump cavitation and the like can vibrate, and if the vibration of the pump can be monitored, measures are taken in advance before a fault occurs, so that the fault can be reduced, the running reliability of the pump can be improved, and the service life of the pump can be prolonged.
Disclosure of Invention
The utility model aims at providing a but submersible sewage pump of area vibration monitoring of real-time supervision vibration.
In order to achieve the above purpose, the utility model adopts the following technical scheme: the utility model provides a take submersible sewage pump of vibration monitoring, submersible sewage pump includes the pump body, and the upper end of the pump body is connected with the motor, is provided with the terminal box that is used for holding the various wiring of motor on the motor, the terminal box be cavity box body form, submersible sewage pump on still be provided with the vibration sensor who is used for gathering submersible sewage pump vibration signal, the signal transmission to submersible sewage pump's switch board that vibration sensor will gather.
Due to the adoption of the technical scheme, the control cabinet can monitor the vibration condition of the submersible sewage pump in real time, and can timely check and effectively solve the problem once the submersible sewage pump is found to have abnormal vibration, so that the occurrence of major faults is avoided, and the operation reliability of the pump is improved.

Detailed Description
The utility model provides a take submersible sewage pump of vibration monitoring, submersible sewage pump 100 includes the pump body 110, and submersible sewage pump 110's upper end is connected with motor 120, is provided with the terminal box 130 that is used for holding the various wiring of motor on the motor 120, terminal box 130 be cavity box body form, submersible sewage pump 100 on still be provided with the vibration sensor 140 that is used for gathering submersible sewage pump 100 vibration signal, the switch board of signal transmission to submersible sewage pump 100 that vibration sensor 140 will gather. The vibration condition that the switch board can real-time supervision dive dredge pump, in case find that there is the vibration anomaly in dive dredge pump, just can in time investigate, effectual solution to avoid the emergence of major failure, improve the operational reliability of pump.
The vibration sensor 140 is located inside the submersible sewage pump 100. Since submersible sewage pump 100 is operated in water, if vibration sensor 140 is also mounted outside submersible sewage pump 100, the protection level requirements for vibration sensor 140 are high, and must reach IP68, which is not possible with common sensors. On the other hand, the sewage is corrosive to a certain extent and contains a lot of impurities, which also influences the working reliability of the sensor. In this regard, the present invention takes the approach of installing the vibration sensor 140 inside the submersible sewage pump 100.
The vibration sensor 140 is located in the terminal block 130.
The vibration sensor 140 is located within the housing of the motor 120.
The junction box 130 is fixed on the motor end cover 121 of the motor 120, a closed cavity is formed between the junction box 130 and the motor end cover 121, and the vibration sensor 140 is located in the cavity.
The motor end cover 121 is provided with a threaded hole for fixing the vibration sensor 140.
The vibration signal collected by the vibration sensor 140 is transmitted to the control cabinet of the submersible sewage pump 100 through the signal line cable 150.
The signal line cable 150 is a shielded cable that is resistant to interference.
The vibration sensor 140 is a piezoelectric velocity sensor.
The piezoelectric speed sensor converts the vibration signal into a current signal of 4-20ma and then transmits the current signal to the control cabinet. Signals are input into a PLC programmable controller in the control cabinet to read data, and real-time data display and alarm value setting are realized through a liquid crystal display screen of the control cabinet. In order to prevent signal interference, the signal wire of the vibration sensor 140 adopts an anti-interference shielded cable
The utility model discloses well vibration sensor 140 can set up in the inside of the pump body 110, also can set up in the casing of motor 120, also can set up in terminal box 130. The utility model discloses preferentially install vibration sensor 140 in the vibration condition of most ability reaction pump, in the terminal box 130 of the installation wiring of can being convenient for again, the vibration condition of reaction submersible sewage pump 100 that this position can be more accurate. The vibration sensor 140 is disposed in a junction box cavity formed by the junction box cover 130 and the motor end cover 121, and is not affected by sewage, and the installation of wiring is very convenient. The utility model discloses simple structure, assembly are convenient, add the repacking slightly on current submersible sewage pump and just can realize the real-time supervision pump body vibration condition. And the utility model discloses preferred can reflect the position installation vibration sensor 140 of the pump body vibration condition the most, its monitoring data's reliability is very high.
