Abstract

The invention discloses a compressor start control method. According to the control timing sequence of a lubricating oil system, an oil pump in the lubricating oil system is made to be in a normal state; when the oil pump in the lubricating oil system is in the normal state, an air cooling motor is started; after the air cooling motor is started, a valve control timing sequence is started, so that an inlet valve, an outlet valve, a loading valve, an isolation valve and an air release valve are controlled; after the loading valve is closed, high-voltage valve closing control is conducted; after high-voltage valve closing control is successful, a high-voltage frequency conversion motor is operated; after the high-voltage frequency conversion motor is normally operated, the rotating speed of the high-voltage frequency conversion motor is adjusted and controlled, so that a compressor works in an optimal state; an anti-surge control valve is closed, so that the compressor is in a normal work state. By the adoption of the compressor start control method, the compressor is safely started, a large amount of labor cost is saved, and malfunction, operation delay and the like which are caused by manual operation are avoided.

Description

technical field [0001] The invention relates to the technical field of industrial automatic control, in particular to a compressor startup control method. Background technique [0002] During the application process of the compressor, the control of the compressor body, motor unit, dry gas sealing system and electrical system all adopt independent manual or automatic control of each unit. Sometimes the operations between the systems are not closely related to the on-site process, resulting in Each system cannot give full play to its advantages, so that each system cannot work in an optimal state. Each system needs someone to be on duty to perform real-time manual operation, which wastes a lot of manpower, and if it is not operated in time during normal operation, it will endanger the safety of each system unit. [0003] In the prior art, when the unit is started, the start-up process is usually manually operated by humans. Once an operation error occurs in a certain link, t...
