How to adjust the two-stage one-regulation valve of a reciprocating compressor
Thread Content
How to use two pressure regulators and one controller to properly manage system pressure and the compressor? What are the key points for control and adjustment, and what are the criteria for doing so? I ask the experienced expert Hai Chuan to provide a detailed explanation
I’m not sure whether your press returns stage by stage or directly from the outlet to the inlet The key point for control is stable system pressure ； 2 ensures that the outlet of each stage of the press does not experience overpressure or overheating.
Backflow control is a method of compressors’ pressure regulation, which involves adjusting the pressure within the range controlled by the process conditions. Furthermore, depending on the type of compression machinery, pressure regulation methods include suction regulation, discharge regulation, backflow regulation, outlet valve regulation, and speed regulation.
What type of compressor? Level 2 compression? When making adjustments, attention should be paid to the exhaust temperature at various levels, the compression ratio, and by adjusting these two factors, the flow rate – as well as the pressure in the subsequent system – can be controlled. It is recommended to check the materials provided by the equipment manufacturer; performance parameters and such are quite important
For a reciprocating machine with two-stage compression, the flow is from the second-stage outlet to the first-stage outlet, and from the first-stage outlet to the inlet buffer tank. That’s what it should be
Control the compressor outlet pressure: reduce it if there is a risk of overcurrent, and increase it if the outlet pressure is high. Increasing it lowers the compression ratio; in emergency situations, turn it off completely to prevent pressure surges
It should be considered a step-by-step return, with two circuits
Returning from the second-level export to the first-level export doesn’t make any practical sense, right?
The primary outlet return buffer tank is used to regulate the exhaust temperature. The 2-to-1 ratio is used to regulate the system pressure
Erfan Er also can control the secondary exhaust temperature
Yes, as for temperature, it’s a bit inferior; there won’t be large fluctuations in temperature, unless affected by external factors. The key is still to control the pressure
