TABLE 1
Fig. 2 is a schematic diagram of data transmission according to the present invention. Forebay liquid level monitoring device is floater level gauge or ultrasonic wave level gauge, through the monitoring to the forebay liquid level, with concrete data transmission to switch board or integrated terminal case, the forebay liquid level data has been set up in advance according to water pump stop pump water level requirement among the control system, when the data that liquid level detection device acquireed are less than water pump stop pump water level, control system stops the pump automatically, avoided because unmanned supervision current pond water level when having fallen to must stop the pump water level, the condition of operation is still drawing water to the water pump, avoid the water pump to produce the cavitation.
The vibration monitoring device is mainly divided into two parts: one is vibration monitoring of the pump head itself. Mainly by detecting vibration data at the position of the guide bearing; and secondly, monitoring the vibration of the motor. Mainly through the vibration data that detects flange and motor cabinet mounted position under the motor. The vibration body data is transmitted to the control cabinet or the integrated terminal box through the vibration monitoring device. The vibration data of the water pump can be gradually increased along with the increase of the service time of the water pump and the abrasion of the wearing parts. Because the service condition of the water pump and the wearing condition of the wearing parts cannot be judged under the condition of not disassembling the water pump, the operation quality of the water pump unit can be reflected only through vibration data. And similarly, the maximum allowable vibration data for normal operation of the unit is set in the control system in advance, and when the data acquired by the vibration detection device is greater than the maximum allowable vibration data, the control system automatically stops the pump to give an alarm to remind an operation and maintenance unit of repairing the water pump unit. The water pump and motor bearing temperature monitoring device mainly monitors the temperature of all rolling bearings used by a unit through temperature sensors such as PT100 and the like, transmits temperature data to a control cabinet or an integrated terminal box, has been set according to the alarm temperature and the shutdown temperature allowed by different bearings in a control system, alarms when the temperature of the bearings reaches the alarm temperature, and automatically stops the pump when the temperature continues to rise to reach the shutdown temperature.
The pressure monitoring device at the outlet of the water pump mainly transmits the pressure of the outlet pipe to the control cabinet or the integrated terminal box through the pressure sensor at the water outlet bent pipe of the water pump unit, and is used for judging whether the water pump runs near the design working condition or not. Because the outlet pipeline of the axial-mixed flow pump unit is not provided with a regulating valve or the valve is fully opened, and the function of regulating parameters is not provided, the judgment that the water pump runs near the designed working condition can be only carried out by the liquid level of the forebay and the outlet pressure of the water pump. If the water pump is operated under the partial working condition, the service life of the water pump is influenced, the efficiency of the unit is low, and waste is caused. The method can provide powerful basis for the later-stage old pump station transformation or energy-saving transformation.
