Gas flows in reciprocating compressors | Flow Control …

Although cylinder valves of a reciprocating compressor may act like a check valve, independent check valves are still needed. One or two check valves should be provided at the discharge line to ensure that gas cannot flow back to the compressor when it shuts down after it has been compressed into the downstream system.

Reciprocating Compressors: A Brief Presentation – What …

In a reciprocating compressor, a volume of gas is drawn into a cylinder; it is trapped, and compressed by piston and then discharged into the discharge line. The cylinder valves control the flow of gas through the cylinder; these valves act as check valves. There are two types of a reciprocating compressors. Fig. 1 shows the classification of Compressors.

Discharge Valve - an overview | ScienceDirect Topics

The suction and discharge valve operation models are given in Fig. 3.Pressure difference between the piston bore and the suction or discharge chamber opens or closes the valves. There are three types of stresses on the valves: (1) a bending stress on the root of the valves when the valves open, (2) a bending stress on the centre of the ports when the valves close, and (3) an impact stress ...

Malfunctions and repair of a reciprocating compressor ...

If an air leak is detected in the discharge tube after stopping - it is necessary to clean the valve, most likely, the check valve is clogged there. When increasing the heating of the compressor head, it is necessary to tighten the norm, replace the piston rings with the detected defect, clean the contaminated surfaces, change the oil to the one indicated in the technical documentation.

Reciprocating Compressors: Startup and Capacity Control ...

(Page 1) There are two main reasons why compressor capacity regulation is used. The most prevalent reason is to adjust the suction flow to match the process demand. The second reason is to save energy. As a rule, capacity control is determined by the compressor discharge pressure. Compressor capacity-control methods are utilized to maintain a required delivery under variable process conditions.

Check Valves for Reciprocating Compressors - …

Compared to fluid sealing and discharge, the media flow isn’t steady; instead, gas “pulses” (through a pipeline) from a reciprocating compressor. This pulsating flow created by the compressor causes the discharge valves to chatter, and while the sound may not be high on your daily list of concerns, the resulting wear or damage to your check valve and downstream components can eventually ...
