Description

Technical Field

[0001] This utility model relates to the field of rinsing equipment technology, specifically a variable flow high-precision rinsing equipment. Background Technology

[0002] In recent years, wind energy has been widely used as a clean energy source, and wind turbines and related equipment have been manufactured and installed in large quantities. As an important component of wind turbines, the lifespan and performance of the gearbox directly affect the operating cost of wind turbines, so it is necessary to develop a flushing device.

[0003] Currently, existing flushing equipment uses conventional motors to drive pumps, which cannot directly change the pump's output flow rate and cannot meet the different flushing flow requirements of different gearboxes. Furthermore, existing technology uses conventional motors with pressure sensors, which can only detect the pump's output pressure and cannot achieve closed-loop control of the output pressure. In addition, existing technology does not include electric heaters and temperature sensors, so it cannot detect and control the temperature of the flushing medium. Moreover, existing equipment uses multi-stage small-sized filters to filter the flushing medium, resulting in frequent filter replacements and affecting work efficiency. At the same time, existing equipment uses solenoid valves with small diameters, which limit the maximum flushing flow rate. Therefore, we propose a variable flow rate high-precision flushing device. Utility Model Content

[0004] The purpose of this invention is to provide a variable flow, high-precision flushing device. It features a continuous, variable flow flushing medium and is equipped with a high-precision filter. This allows for efficient flushing and filtration of various gearbox models, restoring them to optimal working condition, effectively extending their lifespan, and reducing costs. It solves the problems of existing flushing devices that use conventional motors to drive pumps, which cannot directly change the pump's output flow rate and cannot meet the different flushing flow requirements of different gearbox specifications. Furthermore, existing technologies use conventional motors with pressure sensors, which can only detect the pump's output pressure and cannot achieve closed-loop control of the output pressure. Moreover, existing technologies lack electric heaters and temperature sensors, making it impossible to detect and control the temperature of the flushing medium. Additionally, existing equipment uses multi-stage small-diameter filters to filter the flushing medium, resulting in frequent filter replacements and reduced work efficiency. Finally, existing equipment uses solenoid valves with small diameters, limiting the maximum flushing flow rate.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a variable flow high-precision flushing device, comprising a pump device and a second pneumatic three-way valve.

A second check valve is connected to the bottom of the flow meter through a pipe. The bottom of the second check valve is connected to a first oil filter and a second oil filter through pipes respectively.

[0006] Preferably, the output ends of the first oil filter and the second oil filter are connected to a first check valve via a pipeline, and the output end of the first check valve is connected to the upper end of the pump device via a pipeline.

[0007] Preferably, an electrical control cabinet is provided on the right side of the pump device, and the output end of the electrical control cabinet is electrically connected to the input ends of the pump device, the frequency converter motor, the pressure sensor, the electric heater, the first temperature sensor, the first pneumatic three-way ball valve, the flow meter, the second pneumatic three-way valve, and the second temperature sensor respectively via wires.

[0023] Please see Figures 1-4 As shown, this utility model provides a technical solution: a variable flow high-precision flushing device, including a pump device 1 and a second pneumatic three-way valve 12. A variable frequency motor 2 is fixedly installed on the top of the pump device 1. The output end of the pump device 1 is connected to an electric heater 4 through a pipe.

[0025] Through the above technical solutions, such as Figures 1-4 As shown, by setting the first check valve 14, the medium filtered by the first oil filter 6 and the second oil filter 11 can be diverted back into the pump device 1.

Then, the filtered medium returns to the pump device 1 through the first check valve 14.
