[0002] Invista's BDO technology, a large flow rate (6500NM 3 During operation, the drive-end and non-drive-end bearings of acetylene cycle compressors are prone to failure, causing bearing temperatures to rise. In severe cases, this can cause compressor vibration and seal leakage.

[0003] In actual use, acetylene compressors use acetylene gas as the working medium. Currently, the drive-end and non-drive-end bearings of acetylene compressors in the acetylene-aldehyde process are not equipped with temperature monitoring instruments, making online monitoring of bearing temperatures impossible. Similar processes have previously resulted in emergency shutdowns of acetylene compressors due to bearing damage, abnormal bearing temperature rise, and overheating. Utility Model Content

[0004] To address the existing INVISTA BDO process acetylene cycle compressor's drawback of being unable to monitor the bearing temperatures of the drive and non-drive ends in real time, potentially leading to accidents due to high temperatures, the present utility model aims to provide a high-flow acetylene cycle compressor bearing temperature control system. This system enables real-time monitoring of the compressor's drive and non-drive end bearing temperatures, and automatically performs cooling and oiling operations based on changes in the compressor's drive and non-drive end bearing temperatures, thereby preventing compressor accidents due to high temperatures.

[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a large-flow acetylene cycle compressor bearing temperature control system, including an oil tank 1, an oil pump 2, a regulating valve I3, a compressor 4, a regulating valve II5, a temperature sensor 6, a regulating valve III7, a blower 8, a regulating valve IV9, a bearing housing 10, a controller 11, an oil supply pipeline 12, and an oil return pipeline 13.

[0007] The blower 8 is connected to the bearing housing 10 through an air supply pipe. The bearing housing 10 is provided with an air inlet. The regulating valve III 7 and the regulating valve IV 9 are located on the air supply pipe.

[0008] The controller 11 is connected to the oil pump 2 , the regulating valve I 3 , the regulating valve II 5 , the temperature sensor 6 , the regulating valve III 7 , the blower 8 , and the regulating valve IV 9 through signal lines.

[0009] Furthermore, a dustproof net is installed inside the bearing housing 10.

[0010] Furthermore, an oil filter is installed inside the oil tank 1.

[0011] Furthermore, the oil supply port of the oil supply pipeline 12 is located inside the bearing housing 10 , and the oil return port of the oil return pipeline 13 is located outside the bearing housing 10 .

[0012] Furthermore, the temperature sensor 6 is a patch temperature sensor.

[0013] Furthermore, the controller 11 is a programmable logic controller.

[0014] Compared with the existing INVISTA BDO process acetylene cycle compressor drive end and non-drive end bearings, the utility model has the following advantages.

[0015] 1. The utility model discloses a bearing temperature control system for a large-flow acetylene cycle compressor. The system can monitor the temperature of the bearing housing 10 in real time through the temperature sensor 6, indirectly monitor the bearing temperature of the compressor 4, and control the bearing temperature according to the real-time temperature change of the bearing housing 10.

The controller 11 controls the oil pump 2 to supply oil to the bearing housing 10 according to the temperature of the bearing housing 10, which can automatically replenish the lubricating oil evaporated due to high temperature in the bearing. At the same time, the lubricating oil is continuously taken away from the bearing through the oil supply pipeline 12 and the oil return pipeline 13.

[0017] 3. The utility model provides a bearing temperature control system for a large-flow acetylene cycle compressor. The controller 11 controls the blower 8 to supply air to the inside of the bearing housing 10 through the air supply pipe according to the temperature of the bearing housing 10 to reduce the bearing temperature.

For those skilled in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0021] The present invention will be described in further detail below with reference to the accompanying drawings.

[0023] The oil pump 2 is connected to the oil tank 1 through a pipeline. The regulating valve I3 and the regulating valve II5 are located on the oil supply pipeline 12. The oil supply port of the oil supply pipeline 12 is located on the inner side of the bearing housing 10.

[0026] The working process of this system is as follows: in spring and autumn, when the temperature signal sent by the temperature sensor 6 received by the controller 11 exceeds 70 degrees Celsius, it is first determined which side of the bearing of the compressor 4 is overheated. The controller 11 controls the oil pump 2, the blower 8 and the corresponding regulating valve to supply air and inject oil to the bearing housing 10 at the corresponding position and reduce the temperature value to the normal working range; in summer, the above operation is performed when the temperature signal exceeds 80 degrees Celsius; in winter, the above operation is performed when the temperature signal exceeds 60 degrees Celsius.
