The vibration monitor system of existing vertical major axis sea water pump exists integrated inadequately, and when being input to user's DPS data processing system, it is low supporting efficient often to occur.
The model utility content
Unreasonable at existing position, vertical major axis sea water pump monitoring point, problems such as system integration is low, the utility model aim to provide a kind of vertical major axis sea water pump, and this sea water pump is by rationally arranging the monitoring point, the vibration values of reaction pump is convenient to real-time monitoring truly.
To achieve these goals, the technological scheme that adopts of the utility model is:
A kind of vertical major axis sea water pump comprises the pump housing, is contained in the motor on the pump housing, is contained in the pump housing and the main shaft that connects with the output shaft of motor, and the described pump housing has outlet(discharge) flange; Its structural feature is, on the bearing support of described main shaft sensor stand is housed, and is equipped with on this sensor stand for the monitoring main shaft axially and the current vortex sensor of radial displacement; The signal output part of described current vortex sensor links to each other with the signal input part of transducer on being contained in the pump housing, and the signal output part of this transducer links to each other with the signal input part of monitor on being contained in the pump housing.
Below be the technological scheme of further improvement of the utility model:
According to embodiment of the present utility model, described current vortex sensor has two, and one of them is used for the axial displacement of monitoring main shaft, and another is used for the radial displacement of monitoring main shaft, and the radial displacement value of main shaft i.e. the vibration amplitude of axle
Further, the probe of described current vortex sensor and the distance between the main shaft are preferably 1.15mm ~ 1.35mm.
For convenience of sensor probe testing pump vibration values, the probe of described current vortex sensor links to each other with the body of current vortex sensor by conduit.
On the bearing shell of described motor velocity transducer is housed, the signal output part of described velocity transducer links to each other with the signal input part of transducer on being contained in the pump housing.Further, described velocity transducer has two, described bearing shell a speed measuring point axially and radially respectively is set.Because the vibration data of pump is reflected in the bearing shell of motor really, it is more reasonable therefore to install on the motor.
As a kind of concrete data transfer mode, the signal output part of described monitor links to each other with the signal input part of DPS data processing system.
By said structure, the utility model is installed on motor bearing by changing the shell measuring instrument mounting point that shakes with sensor, and a measuring point axially and radially respectively is installed.Increase the current vortex sensor that the monitoring axle shakes, be installed on the sensor stand on the bearing support.Being radially (diverging 90 °) centered by the pump shaft external diameter distributes.This sensor is used for axially and the radially shift value of both direction of the monitoring main shaft diameter of axle, and the radial displacement value of main shaft i.e. the vibration amplitude of axle.The voltage signal of current vortex sensor output changes to the current signal of 0 ~ 20mA, Input Monitor Connector device again through transducer.Monitor focuses on all vibration datas, imports in the user DPS data processing system again.
Compared with prior art, the beneficial effects of the utility model are: the utility model has detected the vibration values of sea water pump truly by the monitoring point reasonably is set, and is convenient to the real-time monitoring to the sea water pump vibration values.
