Oil level monitoring and oil recharging device for gear box of cooling tower

Abstract

The invention discloses an oil level monitoring and oil recharging device for a gear box of a cooling tower, belongs to the field of common large cooling tower equipment, and specifically relates to an oil level monitoring and oil recharging device of a cooling fan gear box for a large counter flow cooling tower. The oil level monitoring and oil recharging device is characterized in that the oil level monitoring and oil recharging device is mounted in an inspection channel at the top of the cooling tower and comprises an oil pipe (9), an oil cup (7) and a fixing bracket (8), wherein the oil cup (7) and the oil pipe (9) are mounted through the fixing bracket (8); and one end of the oil pipe (9) is communicated with an oil outlet of the oil cup (7), while the other end of the oil pipe (9) is communicated with an oil drain hole (403) of the gear box (4) of the cooling tower. The principle that liquid levels of two communicated appliances are equal is ingeniously utilized, a maintenance worker can judge the height of the liquid level of an operating oil level in the gear box by observing the liquid level of the oil level in the oil cup and can safely and conveniently lubricate and maintain the gear box, the gear box is not required to halt no matter whether monitoring or oil recharging is performed, the normal operation of the device is not influenced, and the production efficiency and the production schedule are not influenced.

Description

technical field [0001] An oil level monitoring and oil replenishing device for a cooling tower gearbox belongs to the field of general large-scale cooling tower equipment, and specifically relates to an oil level monitoring and oil replenishing device for a cooling fan gearbox used in a large counterflow cooling tower. Background technique [0002] The cooling fan used in cooling towers for large-scale industrial circulating water systems is usually composed of fan blades, gearboxes, connecting shafts and motors. The gearbox of the cooling fan is installed on the structural frame in the center of the cooling tower, and the upper part of the gearbox is connected to the cooling The blades of the fan, the fan blade group and the gear box are located in the center of the cooling tower shroud, and the motor is installed outside the shroud. The motor drives the gear box to rotate through the connecting shaft, and finally drives the fan blade group to rotate to accelerate the rise ...

AI Technical Summary

Problems solved by technology

[0003] In addition, the cooling tower cavity is harassed by rising hot air flow, the structural frame is relatively narrow, and it is inconvenient for maintenance personnel to stand up, making maintenance work very difficult; moreover, the body of the maintenance personnel is within the rotation range of the cooling fan blades, once the equipment There is a control failure, the fan rotates without starting, and the maintenance personnel are very likely to be mechanically injured

Therefore, the oil replenishment and oil level monitoring work of the gear box of the current cooling tower is relatively cumbersome.
