Description

Technical Field

[0001] This utility model relates to a thin oil lubrication system. Background Technology

[0002] Conventional thin oil lubrication systems use bypass or overflow methods to regulate oil supply flow, resulting in significant power loss, especially when the required flow rate of the main unit differs greatly from the actual oil supply flow rate. Furthermore, the amount of thin oil lubrication required by the main unit varies under different operating conditions, such as high and low loads or high and low speeds. Conventional thin oil lubrication systems cannot achieve online adjustment of the oil supply flow rate to match the lubrication flow rate required by the main unit under different operating conditions, thus leading to over-lubrication and power waste. Utility Model Content

[0003] The purpose of this invention is to provide an intelligent thin oil lubrication system that ensures accurate flow output and has precise temperature control, thereby regulating flow and maintaining constant temperature.

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

[0005] A smart thin oil lubrication system with servo-controlled flow rate and constant temperature control includes an oil tank. The system is characterized by: the oil tank being connected to a servo motor-controlled oil pump; a filter being connected after the oil pump; a water cooler being connected after the filter; and an oil supply line leading to the oil supply port being connected after the water cooler. A flow transmitter and an oil supply temperature sensor are installed on the oil supply line. The cooling water for the water cooler comes from a water tank, which is connected to a cooling water inlet. A servo motor-controlled servo water pump is connected after the water tank, and the servo water pump is connected to the water inlet of the water cooler.

[0006] The oil pump outlet is connected to a safety valve that connects to the oil tank; the servo water pump outlet is connected to a safety valve that connects to the water tank.

[0007] This utility model's lubrication system is equipped with a flow transmitter, using flow detection instead of pressure detection in conventional thin oil lubrication devices. The servo oil pump flow regulation employs closed-loop control to ensure accurate flow output. The lubrication system also includes a servo water pump, whose oil supply temperature is controlled using closed-loop control. Feedback from an oil supply temperature sensor controls the amount of cooling water entering the cooler from the servo water pump, achieving precise temperature control and reducing water and electricity waste caused by excessive cooling.
