Vibration of reciprocating compressors
Thread Content
1 The vibration in the inlet pipeline of a reciprocating compressor is mainly caused by airflow pulsations. So what are the reasons for these airflow pulsations? (High inlet pressure. Can a clogged inlet filter cause this?) 2 What are the reasons for pulsations in the airflow at the outlet of a reciprocating compressor?
Some say it is caused by an excessive processing volume. Why does a high processing volume lead to vibrations, and does a low processing volume not cause them?
The vibration in the inlet pipeline of a reciprocating compressor is mainly caused by airflow pulsations. The reasons for these airflow pulsations include: 1. An unreasonable design of the inlet pipeline； 2. The pipe clamps on the inlet pipeline are not properly secured ； 3. Liquid in the inlet pipeline ； 4. Large fluctuations in intake air flow ； What are the reasons for the pulsation of the airflow at the outlet of a reciprocating compressor? 1. The design of the outlet pipeline is unreasonable ； 2. The outlet pipeline clamps are not properly secured ； 3. The buffer tank at the unit outlet is undersized ； 4. Large pressure fluctuations in the exhaust path ； 5. The inter-stage tank is designed to be small ； 6. The inter-stage piping design is unreasonable, preventing the condensate from being discharged in a timely manner.
Vibration in the inlet and outlet pipelines is a characteristic of reciprocating machines; the key is to minimize it as much as possible. The answer provided above covers this aspect quite comprehensively; please refer to it.
Can insufficient air intake caused by a clogged inlet filter lead to vibrations?
The sound from the pipes is different; the pipelines vibrate, but not too much.
The first-stage cylinder of our compressor experiences high vibration; recently, throttle orifice plates were installed in the first-stage suction buffer tank and the first-stage discharge buffer tank. Things have gotten a bit better.
There are many factors at play; sometimes the layout of the pipelines plays a significant role. Vibration can occur if the volume of the outlet buffer tank is too small, or if there isn’t enough support for the pipelines. In short, there are many reasons
Another reason is that the piston head isn’t properly installed, which is really fatal
