Description

Technical Field

[0001] The utility model relates to the field of compressor unit technical processing, in particular to a compressor unit oil fume separation, recovery and utilization system. Background Art

[0002] Generally speaking, for the operation of expansion units in production equipment, the biggest factor affecting the safe operation of the unit is the damage to the bearings, and the bearing temperature directly affects the stability and reliability of the bearings. Lubricating oil is commonly used to cool the unit, and the lubricating oil adopts a lubrication circulation circuit during the operation of the unit. The lubricating oil also needs to be cooled by water. However, impurities such as scale and solid foreign matter exist in the circulating water pipes. After running for a period of time, the heat exchange channel will be blocked, thereby causing the lubricating oil temperature to rise, affecting the safe and stable operation of the unit, and the normally operating unit does not have the conditions for shutdown and maintenance. Utility Model Content

[0003] The utility model proposes a temporary cooling system for the oil cooler of a unit, which adds an external cooling system and can temporarily cool the lubricating oil when a problem occurs in the heat exchange device, thereby ensuring that the unit does not stop and operates stably.

[0004] The specific plan is as follows:

[0005] A temporary cooling system for an oil cooler of a unit includes a lubricating oil tank, which is connected to the unit via an oil pump through a heat exchanger, and the heat exchanger is connected to a circulating water loop; the heat exchanger outlet pipeline is connected to a temporary cooling pipeline, and the temporary cooling pipeline is connected to an oil pump inlet pipeline; the temporary cooling pipeline includes a valve A and a cooler.

[0006] A pressure gauge and a temperature gauge are provided on the inlet pipeline of the unit to monitor the pressure and temperature of the lubricating oil when it enters the unit.

[0007] A temporary cooling water pipe is also connected to the heat exchanger to increase the cooling effect of the lubricating oil.

[0008] When the circulating water pipe in the heat exchanger is blocked, it is necessary to remove impurities in the circulating water pipe, start the temporary cooling pipeline to cool the lubricating oil, and then replenish the lubricating oil to ensure that the unit does not stop and operates stably. BRIEF DESCRIPTION OF THE DRAWINGS

[0009] Figure 1 .Schematic diagram of the structure of the utility model. DETAILED DESCRIPTION

[0010] like Figure 1As shown, a temporary cooling system for the oil cooler of a unit includes a lubricating oil tank 1, which is connected to the unit 4 through an oil pump 2 via a heat exchanger 3, and the heat exchanger 3 is connected to a circulating water loop 17; the outlet pipe of the heat exchanger 3 is connected to a temporary cooling pipe 5, and the temporary cooling pipe 5 is connected to the inlet pipe of the oil pump 2; the temporary cooling pipe 5 includes a valve A6 and a cooler 7.

[0011] A pressure gauge 8 and a temperature gauge 9 are provided on the inlet pipeline of the unit 4 to monitor the pressure and temperature of the lubricating oil when it enters the unit 4 .

[0012] The heat exchanger 3 is also connected to a temporary cooling water pipe 10 to increase the cooling effect of the lubricating oil.

[0013] When the circulating water pipes in the heat exchanger's circulating water loop 17 become clogged, impurities within the pipes need to be cleared. This can be done by closing valves C11 and D12 of the circulating water loop 17, closing valve B13 on the inlet pipe of unit 4, opening valve A6 on the temporary cooling pipe 5, and closing valve E14 on the outlet pipe of the oil tank 1. Cooler 7 in the temporary cooling pipe 5 and valves F15 and G16 on the temporary cooling water pipe 10 are then activated to circulate and cool the lubricating oil. Valve A6 is then closed, and valve B13 is opened to replenish lubricating oil to unit 4, ensuring stable operation without shutting down. Valve B13 is then closed, and valves A6 and E14 are opened. After replenishing lubricating oil in the temporary cooling pipe 5, valve E14 is closed, and circulating and cooling the lubricating oil is continued before replenishing lubricating oil to unit 4. Cleaning the circulating water pipes in the heat exchanger typically takes about 30 minutes, and the temporary cooling pipe only needs to remain operational for about 30 minutes.

[0014] The above description is only a part of the preferred embodiments of the present invention and does not constitute any form of limitation to the present invention. Any simple modification, equivalent change and modification made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention shall still fall within the scope of the technical solution of the present invention.
