Description

Technical Field

[0001] This invention 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. Summary of the Invention

[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 invention is: An intelligent 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 following the oil pump; a water cooler following the filter; and an oil supply line leading to the oil supply port following 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 originates from a water tank, which is connected to a cooling water inlet. A servo motor-controlled servo water pump is connected to the water inlet of the water cooler. Through a programmable logic controller (PLC), a touchscreen, and a 4G communication module, the system achieves intelligent, visual, and 4G remote transmission functions for servo-controlled flow rate and constant temperature control in the thin oil lubrication system. The system detects temperature, pressure, flow rate, and liquid level parameters by controlling the components. When the set values ​​are reached, a signal is sent to the electrical control cabinet, which then controls a main component of the system to work or issues an audible and visual alarm signal. The electrical control cabinet is used to operate the electrical components of the system and communicate with the main control system. The cabinet is equipped with a servo driver to adjust the oil and water volume to achieve pressure, flow, and temperature control. During operation, the metering water pump draws cooling water from the water tank. The drawn-in cooling water is pressurized by the metering water pump and then transported to the oil tank cooler inlet through the pipeline. The water station section of the intelligent thin oil lubrication system with servo-regulated flow and constant temperature control has a servo metering water pump device. At the same time, the servo metering water pump automatically adjusts its speed according to the deviation of the oil supply temperature of the oil system, thereby increasing or decreasing the cooling water volume to achieve a constant oil supply temperature.

[0005] 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.

[0006] This invention'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.
