Description

Technical Field

[0001] The utility model relates to the technical field of thin oil lubrication, in particular to a constant temperature output type thin oil lubrication cooling device. Background Art

[0002] The thin oil lubrication system is usually equipped with a cooling device for cooling the lubricating oil. Usually, we configure a water cooling device for the thin oil lubrication system. With the increasing attention to the environment and the serious water shortage at many equipment sites, air cooling systems have become the first choice for most new projects in recent years. In the currently equipped air cooling device, a safety valve is often used between the oil inlet pipeline and the cooling pipeline to set the maximum system pressure. The set pressure is slightly higher than the opening pressure of the bypass valve on the air cooler 6. When the system pressure is too high, the lubricating oil in the oil inlet pipeline first passes through the bypass valve, and then overflows to the cooling pipeline through the safety valve, which plays a role in protecting the air cooling device.

[0003] When designing an air cooling device, the average maximum summer temperature over the years at the equipment site is generally used as a calculation parameter to determine the number and specifications of the air cooler 6. When the temperature is relatively low in winter, the cooling power of the air cooler 6 will be relatively large. In this way, when the oil temperature reaches a high set value and the air cooler 6 is turned on to cool the lubricating oil, the oil temperature will drop a lot instantly, exceeding the low set value and shutting down the air cooler 6, causing the air cooler 6 to start and stop repeatedly. At the same time, low oil temperature will also cause a sudden increase in the viscosity of the lubricating oil, a sudden increase in the pressure of the lubricating oil, and further cause the safety valve of the thin oil lubrication station to open and the oil flow to drop sharply. Under such working conditions, it is easy for pipeline connectors, shunt motors and flow meters to be damaged, and the flow to the mechanical equipment to be lower than the set value, causing the mechanical equipment to trip and shut down.

[0024] The present invention is further described in detail below in conjunction with the embodiments and with reference to the accompanying drawings.

[0025] Embodiment 1:

[0026] The utility model discloses a constant temperature output type thin oil lubrication cooling device. Figure 1As shown, Example 1 mainly includes a base 1, two air coolers 6 and a temperature control valve 8, an oil inlet pipeline 3.1, a cooling pipeline 3.2 and an oil outlet pipeline 3.3. Generally, the average maximum temperature in summer over the years at the equipment site is used as a calculation parameter to determine the number and specifications of the air coolers 6. Example 1 takes two air coolers 6 as an example. A bypass valve is installed on the air cooler 6, and the opening pressure of the bypass valve is 5 bar. Valves B5 are installed on the oil inlet and oil outlet of the air cooler 6. The two air coolers 6 and the valves B5 on the oil inlet and outlet are connected in parallel to form an air cooling component.

[0027] The temperature control valve 8 is designed with a temperature control valve oil inlet B18, a temperature control valve oil inlet C19 and a temperature control valve oil outlet A17. The temperature control valve 8 is designed with a thermal sensitive component and a slide valve inside. The sensor inside the thermal sensitive component is very sensitive to temperature changes. The expansion generates stroke and thrust to push the slide valve to move, thereby adjusting the lubricating oil flow through the temperature control valve oil inlet B18 and the temperature control valve oil inlet C19. After the hot oil and the cold oil are mixed, the lubricating oil in a fixed temperature range can be output to achieve the effect of constant temperature output.

[0028] The oil inlet pipeline 3.1 is connected to the oil inlet valve B5 of the air cooling component and the oil inlet B18 of the temperature control valve. The valve A4 and the thermometer 7 are installed on the oil inlet pipeline 3.1. One end of the oil inlet pipeline 3.1 is the oil inlet P13, and the other end is the spare oil port 16, which is blocked with a plug. The cooling pipeline 3.2 is connected to the oil outlet valve B5 of the air cooling component and the oil inlet C19 of the temperature control valve.

[0029] The oil outlet pipeline 3.3 is installed with a valve A4 and an instrument assembly. One end of the oil outlet pipeline 3.3 is connected to the oil outlet A17 of the temperature control valve, and the other end is the oil outlet P14. The oil inlet P13 is connected to the oil outlet pipeline of the lubrication pump of the thin oil lubrication station, and the oil outlet P14 is connected to the oil inlet pipeline of the mechanical equipment. The instrument assembly is installed with a pressure gauge 9, a pressure sensor 10, a thermometer 7, a temperature sensor 11 and a flow meter 12, which can perform manual observation and electrical detection of the pressure, temperature and flow of the output lubricating oil.

[0030] All the above parts are installed on the base 1, and valve A4 and valve B5 are manual valves.

[0031] During operation, valve A4 and valve B5 are fully opened, and the lubricating oil at the oil outlet of the lubricating pump of the thin oil lubrication station flows through valve A4 and oil inlet pipeline 3.1 through oil inlet P13, and the oil inlet temperature can be read by thermometer 7; part of the lubricating oil flows to the oil inlet B18 of the temperature control valve, and part of the lubricating oil flows to valve B5 and enters the air cooler 6 for cooling. The cooled lubricating oil flows out to the cooling pipeline 3.2 through valve B5, and then flows to the oil inlet C19 of the temperature control valve. The cooling oil temperature can be read by thermometer 7. The hot oil flowing into the oil inlet B18 of the temperature control valve and the cold oil flowing into the oil inlet C19 are mixed through the temperature control valve 8 and flow out from the oil outlet A17 to the oil outlet pipeline 3.3. The lubricating oil on the oil outlet pipeline 3.3 flows out from the oil outlet P14 through the instrument assembly and valve A4, and flows to the oil inlet pipeline of the mechanical equipment.

[0032] The pressure gauge 9, pressure sensor 10, thermometer 7, temperature sensor 11 and flow meter 12 on the instrument assembly can perform manual observation and electrical detection on the pressure, temperature and flow of the output lubricating oil.

[0033] By comparing the values ​​of the thermometers 7, the cooling effect of the air cooling component and the working state of the temperature control valve can be determined.

[0034] When the temperature is low in winter, under the premise of ensuring the cooling effect, in order to save electricity, the power supply and the oil inlet and outlet valves of one of the air coolers 6 can be turned off.

[0035] When the temperature is high in summer, or when the heat generated by mechanical equipment is too high, the cooling power may be insufficient. At this time, the plug on the spare oil port 16 can be removed, and a newly added air cooler 6 or water cooler can be connected in parallel to the existing equipment. The spare oil port 16 provides convenience for subsequent equipment modification.

[0036] Embodiment 2:

[0037] The difference between this embodiment and embodiment 1 is that an oil collecting groove 2 is installed around the base 1 for collecting the overflowed lubricating oil. The oil collecting groove 2 has a certain slope. A drain outlet 15 is designed on the lowest oil collecting groove 2 for discharging the collected lubricating oil. The number of drain outlets 15 is generally 2, and the specific number is determined according to the length of the oil collecting groove 2. The drain outlet 15 is blocked with a plug. When a large amount of lubricating oil is collected, the plug is opened for discharge.

[0038] It should be noted that the parts not described in detail in the above embodiments are all prior art.

[0039] The above is only a preferred embodiment of the present invention and does not constitute any form of limitation to the present invention. Although the present invention has been disclosed as a preferred embodiment as above, it is not intended to limit the present invention. Any technician familiar with the profession can make some changes or modify the technical contents disclosed above into equivalent embodiments without departing from the scope of the technical solution of the present invention. However, 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 be included in the protection scope of the present invention.
