Description

Technical Field

[0001] This utility model relates to a hydraulic lubrication device for a dynamically adjustable fan. Background Technology

[0002] The existing hydraulic lubrication system for dynamically adjustable fans cannot operate independently; the hydraulic and lubrication pumps affect each other, impacting performance and efficiency. Furthermore, the oil tank temperature in existing dynamically adjustable fans is prone to overheating. Utility Model Content

[0003] The purpose of this utility model is to provide a dynamic adjustment fan hydraulic lubrication combined device that allows hydraulic and lubrication processes to operate independently, with the hydraulic and lubrication oil pumps not affecting each other, and prevents the oil tank temperature from getting too high and ensures the oil temperature in the tank.

[0004] The technical solution of this utility model is:

[0005] A hydraulic lubrication system for a dynamically adjustable fan, employing a throttle valve for flow diversion, includes an oil tank. The oil tank is connected to an independent hydraulic oil supply system and an independent lubrication oil supply system. The independent hydraulic oil supply system comprises two parallel hydraulic oil pumps, one in operation and one on standby. A filter device, consisting of two parallel filters, is connected after each hydraulic oil pump. A pipeline following the filter device leads to an oil outlet, and a high-pressure ball valve is installed on this pipeline. The independent lubrication oil supply system comprises two parallel lubrication oil pumps, one in operation and one on standby. A filter device, consisting of two parallel filters, is connected after each lubrication oil pump. A cooling device, consisting of two parallel water coolers, is connected after each cooling device, and a pipeline following the cooling device leads to an oil supply port. A throttle valve is installed at the cooler outlet to divert excess circulating cooling oil back to the oil tank.

[0006] Two hydraulic oil pumps connected in parallel are connected to parallel pressure regulating valves. Two lubricating oil pumps connected in parallel are connected to parallel pressure regulating valves.

[0007] This invention employs independent hydraulic and lubrication oil pumps for oil supply, each equipped with its own electric motor. The hydraulic and lubrication oil pumps operate independently, allowing each to be maintained online separately, ensuring continuous system operation and facilitating fan blade angle adjustment and bearing lubrication and cooling. A throttle valve at the cooler outlet diverts excess circulating cooling oil back to the oil tank to neutralize the oil temperature, preventing overheating and maintaining optimal oil temperature.
