By adopting the technical scheme, the high-speed motor direct-drive turbine and the compressor have any abnormal conditions in the operation process, and the sliding bearing of the high-speed motor can be normally lubricated, so that the service life of the sliding bearing of the high-speed motor is well ensured. The main electric oil pump (8) and the auxiliary electric pump (9) on the oil tank (6) are arranged in the oil tank (6), and when the main electric oil pump (8) operates, the main electric pump (8) sucks lubricating oil and conveys the lubricating oil into the high-speed motor (10) through the oil pipe fitting group (3). The outlet of the main electric oil pump (8) is provided with a temperature control valve (5), the temperature control valve (5) is in a three-way form, when the temperature of lubricating oil is higher than a set value (40 ℃) of the temperature control valve (5), the valve inside the temperature control valve (5) is automatically closed, and the lubricating oil can enter the high-speed motor (10) after being cooled by a cooler (7); when the temperature of the lubricating oil is lower than the set value (40 ℃) of the temperature control valve (5), the valve inside the temperature control valve (5) is automatically opened, and the lubricating oil can directly enter the high-speed motor (10) without passing through the cooler (7); meanwhile, lubricating oil reaches the oil inlet of the motor through the filtration of the oil filter (4), and the high-speed motor sliding bearing is ensured to be in an optimal lubrication state through the control of the temperature of the lubricating oil and the removal of impurities in the oil. The oil pressure transmitter (11) and the temperature sensor (12) are arranged at the oil inlet of the high-speed motor, the oil pressure transmitter (11) can detect the pressure of lubricating oil, the temperature sensor (12) detects the temperature of the lubricating oil, when the pressure of the lubricating oil is lower than a set value (such as 0.1MPa/0.08 MPa), the control program carries out interlocking alarm or stop, when the temperature of the lubricating oil is higher than the set value (such as 50 ℃), the control program carries out interlocking alarm, and the high-speed motor sliding bearing is well protected through interlocking alarm or stop, so that the influence of severe lubricating oil working conditions on the service life of the high-speed motor sliding bearing is avoided. The auxiliary electric pump (9) is used as a standby state of the standby pump when the main electric oil pump (8) is operated; when the main electric oil pump (8) is in fault and stops, the oil pressure transmitter (11) can detect the pressure drop of lubricating oil, and when the pressure drop is reduced to a set value (0.12 MPa), the control program enables the auxiliary electric pump (9) to be started in an interlocking way, so that the oil supply pressure is ensured to be increased to be in a normal range, and the sliding bearing of the high-speed motor (10) is subjected to continuous lubrication and cooling. The electric oil pump (8) supplies oil to the energy accumulator (2) to ensure that a certain amount of lubricating oil is stored in the energy accumulator (2), and the stored oil can be continuously supplied for 30 seconds; when emergency such as power failure occurs, the main electric oil pump (8) and the auxiliary electric pump (9) can not run at the same time, the lubricating oil stored in the accumulator (2) can continuously lubricate the sliding bearing of the high-speed motor (10) in a short time, and the phenomenon that the sliding bearing is burnt out due to high temperature generated by dry grinding of the motor rotor and the bearing in the process of stopping rotation when the rotation speed of the motor rotor is reduced is avoided, so that the sliding bearing of the high-speed motor is well protected.
Therefore, the utility model is a safe and reliable high-speed motor direct-drive turbine lubrication system with few fault points.
