Description

Technical Field

[0001] The utility model belongs to the technical field of oil monitoring, and in particular relates to an integrated bypass type online oil monitoring station. Background Art

[0002] The rotating parts (bearings, gears, etc.) of large-scale power machinery and equipment use lubricating oil to reduce friction, reduce drag, lubricate and cool. Abrasive wear is the most common and main failure form of rotating parts, and the size ranges from a few microns to hundreds of microns. The larger the abrasive particles, the more serious the loss of the rotating parts; the larger the accumulated amount of abrasive particles, the more serious the wear of the rotating parts. Abrasive particles flow out of the rotating parts under the flushing of lubricating oil. Therefore, online monitoring of the size and accumulated amount of abrasive particles in the oil can indirectly realize online monitoring of the wear status of the rotating parts of large-scale power machinery and equipment, which is very important for improving the reliability and safety of the operation of large-scale power machinery and equipment.

[0003] Existing online monitoring equipment for wear particles is generally connected to the main pipeline. The oil to be measured needs to flow through the sensor at a very fast speed for measurement, and it is unable to measure wear particles below 100 microns. Many equipments that cannot flow quickly or have less wear cannot be used. Summary of the invention

[0024] Bypass oil monitoring station operation process:

[0025] When the oil inlet pipeline 8 and the oil outlet pipeline 2 of the bypass oil monitoring station are connected to the main oil circuit, a bypass channel is formed. Since there is almost no pressure difference and the oil viscosity is relatively high, the oil in the bypass channel hardly flows and cannot be measured. At this time, after the oil pump assembly 22 is powered on, the oil pump starts to suck oil, and the oil in the bypass channel starts to flow: the oil enters the oil sensor 15 through the oil pipe 1 13 from the oil inlet pipeline 8, flows through the oil pipe 2 16 after coming out of the oil sensor 15, passes through the oil pipe 3 20 after passing through the filter 21 at the oil pump inlet, and then passes through the buffer 19 to reach the oil outlet pipeline 2 and flow back to the main pipeline. After the oil flows through the oil sensor 15, the abrasive particles, moisture and viscosity parameters can be measured. Inside the equipment, all wires are connected to the corresponding equipment through the wire trough 12 and the side wire trough 17. All equipment grounding wires are connected to the grounding bar 11, and the oil pump assembly 22 wires are connected to the motor drive controller 23. After the antenna 10 receives the control command, the gateway 18 performs signal processing. After the gateway converts the signal, it sends an instruction to the motor drive controller 23, and the motor drives the oil pump assembly to control the switch speed. The abrasive information collected by the sensor will be converted into a signal through the gateway after internal processing and transmitted to the designated location by the antenna.
