Description

Technical Field

[0001] This utility model relates to a compressor lubrication regulating oil station. Background Technology

[0002] The existing compressor lubrication regulating oil station has two independent systems for lubricating oil and regulating oil, which are large in size. In addition, it has defects such as unstable pressure, poor flow stability and poor temperature stability during operation. Further improvements are needed. Utility Model Content

[0003] The purpose of this invention is to provide a compressor lubrication regulating oil station that provides stable pressure, smooth flow, and good temperature stability during operation.

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

[0005] A compressor lubrication regulating oil station includes an oil tank, characterized in that: the oil tank is connected to a main oil pump and an auxiliary oil pump; the main oil pump is connected to a lubricating oil cooler; the lubricating oil cooler is connected to a filter; the oil path after the filter is divided into two paths, one of which is connected to an oil supply port and is equipped with a first self-regulating pressure regulating valve; the other path is a branch path directly connected to a high-pressure lubrication oil supply port; a self-regulating temperature control valve is connected between the lubricating oil cooler and the filter; the outlet of the auxiliary oil pump is divided into two paths, one of which is connected to the self-regulating temperature control valve, and the other path is connected to the oil path after the filter through a second self-regulating pressure regulating valve; the oil tank is connected to an exhaust fan.

[0006] A first maintenance valve is connected in parallel between the first and second ends of the self-operated temperature control valve, and a second maintenance valve is connected in parallel between the first and third ends of the self-operated temperature control valve.

[0007] This utility model integrates the lubricating oil and regulating oil systems into one unit, resulting in a smaller and more compact lubrication and regulating oil station. A self-regulating pressure regulating valve automatically adjusts the oil pressure by changing the valve opening, ensuring stable pressure and flow during operation. Similarly, a self-regulating temperature control valve automatically adjusts the temperature by changing the valve opening, ensuring stable temperature during operation. An exhaust fan is included to prevent secondary environmental pollution, significantly reduce lubricating oil consumption, and maintain a slight negative pressure inside the oil tank, ensuring normal oil return from the main unit. Attached Figure Description

[0008] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0009] Figure 1 This is a structural schematic diagram of one embodiment of the present invention. Detailed Implementation

[0010] A compressor lubrication regulating oil station includes an oil tank 1, which is connected to main and auxiliary oil pumps 2 and 3. The main oil pump is connected to a lubricating oil cooler 4, which is connected to a filter 5. The oil path after the filter is divided into two paths. One path is connected to an oil supply port 6, which is equipped with a first self-regulating pressure regulating valve 7. The other path is a branch path 8 that directly leads to a high-pressure lubrication oil supply port. A self-regulating temperature control valve 10 is connected between the lubricating oil cooler and the filter. The outlet of the auxiliary oil pump is divided into two paths. One path is connected to the self-regulating temperature control valve 10, and the other path is connected to the oil path after the filter through a second self-regulating pressure regulating valve 9. An exhaust fan 11 is connected to the oil tank.

[0011] A first maintenance valve 12 is connected in parallel between the first and second ends of the self-operated temperature control valve, and a second maintenance valve 13 is connected in parallel between the first and third ends of the self-operated temperature control valve.

[0012] The compressor lubrication regulating oil station uses two self-operated pressure regulating valves to control the oil pressure at the oil pump outlet and the oil station outlet. This ensures that the lubrication regulating oil station can maintain stable pressure and steady flow during operation, thus improving the safety and stability of the equipment.

[0013] The self-regulating temperature control valve regulates the temperature. The lubrication regulating oil station uses a self-regulating temperature control valve to control the oil supply temperature. The regulating valve will automatically adjust by the change of its own opening degree, so that the lubrication regulating oil station can always maintain a stable temperature during operation, which improves the safety and stability of the equipment.

[0014] The exhaust fan not only effectively removes particulate impurities, atomized oil fumes, and water vapor from the oil tank exhaust, preventing secondary environmental pollution and significantly reducing lubricating oil consumption, but also maintains a slight negative pressure inside the oil tank, ensuring normal oil return from the main unit.
