Description

Technical Field

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

[0002] Existing hydraulic lubrication systems for dynamically adjustable fans cannot operate independently in terms of hydraulic pressure and lubrication; the hydraulic and lubrication oil pumps affect each other, impacting performance and efficiency. Furthermore, existing hydraulic lubrication systems for dynamically adjustable fans cannot precisely adjust the oil supply, affecting lubrication and cooling effectiveness. Utility Model Content

[0003] The purpose of this utility model is to provide a hydraulic lubrication combined device for a dynamic fan that allows for independent hydraulic and lubrication processes, with the hydraulic and lubrication oil pumps not affecting each other, and enables precise adjustment of the oil supply.

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

[0005] A hydraulic lubrication system for a dynamically adjustable fan includes an oil tank, characterized in that: 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 includes two hydraulic oil pumps connected in parallel, one in operation and one on standby, a filter device is connected after the hydraulic oil pumps, the filter device consists of two filters connected in parallel, the pipeline after the filter device leads to the oil outlet, and a high-pressure ball valve is installed on the pipeline after the filter device; the independent lubrication oil supply system includes two lubrication oil pumps connected in parallel, one in operation and one on standby, a filter device is connected after the lubrication oil pumps, the filter device consists of two filters connected in parallel, a cooling device is connected after the filter device, the cooling device consists of two water coolers connected in parallel, the pipeline after the cooling device leads to the oil supply port, and a flow meter is installed on the pipeline after the cooling device.

[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 flow meter precisely monitors the oil supply flow at the lubrication oil outlet; this flow meter allows for real-time monitoring of the actual flow rate provided by the equipment. Precise adjustment of the oil supply volume ensures optimal lubrication and cooling of the bearings. Attached Figure Description
