Bearing outer ring raceway is spherical shape, with a self-aligning feature, the inner circle at the center line and the center line to the relative tilt does not exceed 2.50, the bearing can still work. The guide on the most commonly used pump deep groove ball bearings, the same size spherical roller bearings compared to the impact of intolerance, not suitable to withstand heavy loads, poor self-aligning capability, when compared to shell hole tilt 0.20, will affect bearing life. Installation of measuring point: the rack X, Y, Z direction vibration; the lower frame X, Y, Z direction vibration; coupling motor side X, Y direction swing; key phase; the pump guide at the X, Y, Z direction vibration; guide at the pump X, Y direction swing (specifically see Figure 1); outlet valve opening; after pressure pump outlet valve; pump outlet valve before the water pressure; pump inlet pressure.
SJ90 swing vibration function Structure 2.1 Functions SJ90 mainly provides real-time online monitoring and alerting to abnormal pump condition monitoring, using a standard 19 inches and a half wide indeed inserted box structure, the use of embedded hardware and embedded LINUX operating system. The modular hardware design, including the CPU module, power module, function module and so on. Selected according to the type of measurement points corresponding function modules, and supports hot plug, color LCD, not only has an amplitude display, alarm function, but also has a bar graph, measuring point time domain waveform diagram, spectrum analysis, waterfall, trend analysis diagram, Orbit analyzed patterns.
Monitoring types include speed, vibration, swing, pressure pulsation, with a high degree of integration, functional, etc., corrosion resistant matte pump also has some scalability and configuration flexibility is a real pump ideal condition monitoring equipment management. Structure of the device structure of the device is as follows: Chassis: SJ90 standard 19-inch, half-width plug-in box, mainly by the plug-in box, slots, backplane, panels and other components, including the LCD panel, shield, function keys, warning lights and USB interface.
