Speed-adjustable cooling device for lubricating oil of agricultural water pump

Abstract

The invention discloses a speed-adjustable cooling device for lubricating oil of an agricultural water pump. The speed-adjustable cooling device comprises a temperature detection system, a cooling device and a control system. The cooling device is arranged at the outer portion of a lubricating oil storage device of the water pump and communicates with the lubricating oil storage device of the water pump. The control system is electrically connected with the temperature detection system and the cooling device. By means of the cooling device for the lubricating oil of the agricultural water pump, the temperature of the lubricating oil is detected through a temperature sensor, a single-chip microcomputer can judge whether cooling needs to be conducted or not in a control manner according to the temperature of the lubricating oil, meanwhile, the rotating speed of an output shaft of a servo motor is adjusted according to the temperature of the lubricating oil, energy conservation and environment friendliness are achieved, meanwhile, the temperature of the lubricating oil is reduced, the rigidity of a bearing is improved, and therefore the service life of the water pump is prolonged.

Description

technical field [0001] The invention relates to the technical field of agricultural water pumps, in particular to an adjustable-speed cooling device for lubricating oil of agricultural water pumps. Background technique [0002] Water pumps are commonly used pumping tools in farmland, but the working environment is harsh, which reduces the service life of water pumps. As one of the important substances to reduce friction and improve the service life of water pumps, lubricating oil plays a very important role. But working for a long time, the lubricating oil will generate heat due to friction, which will affect the work efficiency. During the operation of the water pump, the temperature of the bearing is up to 85 degrees, and generally runs at about 60 degrees. If the temperature of the lubricating oil is too high, it will affect the strength and rigidity of the bearing. Contents of the invention [0003] Aiming at the problems existing in the above-mentioned prior art, the...
