Problems solved by technology

[0003] The current turbine compressor oil system cannot realize the self-starting of the auxiliary oil pump. In the event of a failure, the auxiliary oil pump is artificially started, and the time lags, causing fluctuations in the lubricating oil pressure system, resulting in compressor shutdown accidents from time to time

Embodiment Construction

[0013] In order to ensure the long-term safe operation of the compressor, the control circuit of the present invention realizes the intelligent self-starting function of the oil system, and the main purpose is to regulate the oil system of the turbine compressor under various operating modes of the turbine compressor. Start-stop operation, and in abnormal or faulty state, the interlock system can act timely and accurately and handle emergency accidents instead of operators, so as to ensure equipment and personal safety, effectively handle faults, and avoid accidental parking or accident expansion.

[0014] The present invention first collects the compressor start-stop signal of the main oil pump and the low pressure signal of the oil pump; when the oil system is in normal circulation, the control circuit controls the auxiliary oil pump to stop automatically when the main oil pump is running and there is no low oil pressure alarm; when the main oil pump of the compressor is norma...

Abstract

The invention discloses a control circuit of a turbocompressor oil system. The control circuit is characterized in that firstly the control circuit collects compressor starting and stopping signals and lower-pressure oil pump signals of a main oil pump; when the oil system is in normal circulation, the control circuit can control an auxiliary oil pump to automatically stop when the main oil pump is in operation and a low oil pressure alarm is not given out; the control circuit can start the auxiliary oil pump immediately when the main oil pump of the compressor runs normally and the low oil pressure alarm is given out; and when the main oil pump stops, the control circuit controls the auxiliary oil pump to be automatically started immediately. As the structure is adopted, the control circuit disclosed by the invention has the advantages that the auxiliary oil pump can be automatically started immediately under the condition of faults; a manual starting/stopping function can be added, so that the whole system can be relatively safe and reliable; the starting and stopping operations of the turbocompressor oil system can be normalized; and the safety of equipment and persons can be guaranteed, and the mis-parking or the accident expansion can be avoided.

Description

technical field [0001] The invention relates to a turbine compressor oil system, in particular to a control circuit of the turbine compressor oil system. Background technique [0002] The function of the turbine compressor oil system is to supply oil to each bearing of the unit, reduce the friction loss of the bearing contact surface and take away the heat generated by friction and the heat transmitted by the rotor; supply the speed regulating system and protection device with stable and sufficient pressure Oil to make it work normally; supply lubricating oil to each transmission mechanism. Therefore, the stable operation of the oil system is very important for the long-term safe operation of the turbocompressor. [0003] The current turbine compressor oil system cannot realize the self-starting of the auxiliary oil pump. In the case of a fault, the auxiliary oil pump is manually started, and the time lags, causing fluctuations in the lubricating oil pressure system, result...
