[0011] Figure 1 It is a schematic structural diagram of an embodiment of the present utility model. Detailed implementation manners

[0012] A dynamic adjustment fan bearing lubrication device includes a parallel dual-pump oil circuit communicated with an oil tank 1. Each oil circuit of the parallel dual-pump oil circuit includes an oil pump 2. A check valve 3 is connected behind the oil pump, and a throttle valve 4 is connected behind the check valve. One oil pump in the parallel dual-pump oil circuit is in use and the other is in standby. The parallel dual-pump oil circuit is connected to a double-barrel filter 5 behind, and the double-barrel filter is connected to a parallel dual-cooler oil circuit. Each oil circuit in the parallel dual-cooler oil circuit includes a ball valve 6. A plate cooler 7 is connected behind the ball valve, and a control valve 8 is connected behind the plate cooler. The parallel dual-cooler oil circuit is connected to an oil outlet oil circuit. A temperature detection instrument 9, a pressure transmitter 10, and a throttle valve 11 are sequentially arranged on the oil outlet oil circuit. The throttle valve leads to an oil outlet 12, and a flow switch 13 is connected between the throttle valve and the oil outlet.

[0013] An oil throttle circuit 14 directly leading to the oil tank is connected in front of the throttle valve on the oil outlet oil circuit, and a throttle valve 15 is arranged on the oil throttle circuit.

[0014] Oil return ports 16 and 17 communicate with the oil tank 1 through an oil return oil circuit, and the oil return oil circuit communicates with an air balance port 18.

[0015] The present utility model can integrate the dynamic adjustment fan bearing and the motor bearing. Through the adjustment of the high-precision mechanical flow switch at the oil supply port and the throttle valve, the oil flow required for entering the bearing can be accurately adjusted, so that the bearing reaches the most ideal lubrication and cooling effect. Features: The mechanical flow switch is provided with a supporting piston. When the oil passes through the flow switch, the piston is extruded and the spring is compressed at the same time. While the spring is compressed, the pointer on the flow switch is driven to move. On-site, the throttle valve can be adjusted to move the pointer of the flow switch to the required flow scale position, so that the oil flow required for entering the bearing can be accurately adjusted, and the bearing reaches the most ideal lubrication and cooling effect.

[0016] A pressure transmitter is installed at the oil supply port of the lubrication device. According to the data fed back by the pressure transmitter, the system can be reasonably maintained to ensure the more effective long-term operation of the lubrication device.

[0017] The dual-cooler is adopted to cool the oil. Two coolers are designed in the system to cool the oil. When the system is running, it can be adjusted in real time according to the on-site ambient temperature and the cooling water temperature. When the ambient temperature is low, a single cooler is used to cool the oil. When the ambient temperature is high, the two coolers are used simultaneously to ensure that the oil temperature of the system meets the operation requirements.
