Description

Technical Field

[0001] This utility model relates to the field of mechanical engineering technology, specifically a high-pressure load shearing device. Background Technology

[0002] The existing water pump thrust bearings all use oil pans to hold lubricating oil. After a long period of shutdown, the lubricating oil in the oil pan is in a static state, and there is no lubricating oil between the thrust bearing and the mirror plate. Direct startup will cause the unit to burn the bearing.

[0003] To address the aforementioned issues, we propose a high-pressure load shedding device. This device injects high-pressure oil into the thrust bearing surface during pump startup and shutdown, creating an oil film between the thrust bearing and the mirror plate to prevent dry friction that could lead to bearing burnout and ensure safe pump operation.

[0029] Instructions for use

[0030] When using the thrust bearing high-pressure unloading device for the first time, run the device first when starting the water pump, then start the water pump. First, pour the high-pressure oil into the inside of the inlet flange 11. Then, through the connection between the inlet flange 11 and the filter connection pipe 2 7, the high-pressure oil will enter the inside of the filter 6 along the filter connection pipe 2 7. After being filtered by the filter 6, start the motor 1. The rotation of the motor 1 will drive the oil pump 4 fixedly connected to its bottom to start. The oil pump 4 is connected to the filter 6 through the filter connection pipe 1 5, thereby drawing the filtered high-pressure oil into the inside of the oil pump 4. Then, through the other end of the oil pump 4... The one-way valve connecting pipe 15, which is fixedly connected to the side, introduces high-pressure oil into the interior of the one-way valve 9. When the pressure raised by the high-pressure oil reaches the specified requirements, it will enter the interior of the thrust bearing and then establish an oil film to prevent bearing burnout. After the water pump finishes running, the one-way valve 9 will close, thereby discharging excess oil through the overflow port 12 via the connection between the one-way valve 9 and the oil outlet pipe 8. The remaining excess oil can also be discharged through the connection between the overflow valve 10 and the overflow pipe 14. When used again, the start and stop of the thrust bearing high-pressure unloading device can be controlled by remotely controlling the start and stop of the motor 1 and the oil pump 4.
