What are the Inspection Contents of Hitachi Screw Compressor？
Apr 15, 2023
The inspection content of Hitachi screw compressor usually includes the following aspects:
1. Exhaust capacity: Check whether the exhaust volume of the compressor meets the design requirements, whether there is air leakage or unstable pressure, etc.
2. Start-up performance: Check the start-up time of the compressor, whether the start-up current is normal, and whether there are problems such as difficulty in starting.
3. Vibration and noise: Check whether the vibration level of the compressor is lower than the standard requirement, and whether the noise level meets the national standard.
4. Running current: Check whether the current of the compressor is stable during operation, and whether there are problems such as current overload or insufficient current.
The specific detection steps and methods can refer to the following aspects:
1. Exhaust capacity detection: During the operation of the compressor, the displacement of the compressor is calculated by detecting the difference between the outlet pressure and the inlet pressure. If the displacement does not meet the design requirements, it is necessary to check whether there is gas leakage, etc. question.
2. Start-up performance test: By checking the start-up time, start-up current and start-up difficulty of the compressor, it can be judged whether the start-up performance of the compressor is normal. If there is a problem, it is necessary to find out the cause and carry out corresponding maintenance.
3. Vibration and noise detection: By using vibration and noise detection instruments, it is possible to detect whether the vibration and noise levels of the compressor meet the standard requirements. If there is a problem, it is necessary to adjust the equipment or replace the corresponding parts.
4. Running current detection: By detecting the current level of the compressor during operation, it can be judged whether it is running normally. If the current is unstable or too high, corresponding maintenance or replacement of relevant parts is required.
