Description

Technical Field

[0001] This utility model belongs to the field of lubrication, specifically relating to an automatic oil supply device for gearboxes used in large cooling towers. Background Technology

[0002] Cooling towers are large-scale devices widely used in industrial production, primarily for lowering water temperature to meet cooling requirements. Due to their enormous size, the gearboxes of cooling towers are correspondingly very tall. Regular inspection and maintenance are essential to ensure efficient operation and long-term stability.

[0003] Currently, gearboxes in cooling towers often require lubricant changes during maintenance, which are mostly done manually. This not only poses a safety risk to workers but also requires machine shutdown each time, disrupting production. Therefore, designing an automatic gearbox lubrication system capable of replenishing the gearbox lubricant from the ground is essential. Utility Model Content

[0004] To address the problems mentioned in the background, this utility model provides an automatic gearbox oil supply device for large cooling towers, which can automatically replenish the gearbox lubricating oil inside the cooling tower, reducing maintenance difficulty and ensuring the personal safety of workers.

[0005] To achieve the above objectives, the specific technical solution of this utility model is as follows:

[0006] An automatic oil supply device for a gearbox in a large cooling tower includes a lubricating oil tank. A control box and a lubricating oil supply tank are installed at the upper end of the lubricating oil tank. A controller is installed inside the control box, and an explosion-proof junction box is connected to the control box. A plunger pump is installed inside the lubricating oil supply tank and extends downward into the lubricating oil tank. An air intake device and a lubricating oil output device are installed on the plunger pump. The plunger pump is electrically connected to the controller.

[0007] As a further feature of the above solution, the lubricating oil output device is equipped with a control valve and a pressure gauge. The control valve can control the oil output of the lubricating oil output device, and the pressure gauge can detect the working pressure of the lubricating oil output device to ensure the stable operation of the device.

[0008] As a further feature of the above scheme, the lubricating oil tank is equipped with a visual level gauge and an inspection port, and an oil drain valve is provided at the bottom of the lubricating oil tank.

[0009] As a further provision of the above scheme, the lubricating oil tank is equipped with a heating device and a level gauge. The heating device includes a thermocouple, which is inserted vertically downward into the lubricating oil tank. The lower end of the thermocouple is connected to a heater. The thermocouple controls the heater to heat the lubricating oil in the lubricating oil tank. The level gauge is used to detect and assist in controlling the lubricating oil level.

[0010] This utility model has the following beneficial effects:

[0011] By installing a lubrication supply tank and control box on the lubrication oil tank, and in conjunction with a plunger pump, lubricating oil is automatically supplied to the gearbox through the lubrication oil output device, avoiding manual replacement of lubricating oil during maintenance, reducing maintenance difficulty, and ensuring the personal safety of workers.
