High-pressure plunger pump piping
Thread Content
Issues related to the piping design of high-pressure three-plunger pumps; in order to eliminate pump vibration, can high-pressure flexible connectors be used in the pipe section between the pump outlet and the check valve? Is there a theoretical basis? Where is that theoretical basis? See the schematic diagram below.
Basic physical knowledge: in a rigid connection, energy is transmitted directly with minimal losses at intermediate stages； The energy of the flexible connection has been exhausted. It’s like what your car would be like if it didn’t have springs for shock absorption.
This can’t eliminate pump vibration, right? . It is simply to reduce the stress at the pipe connections, thereby preventing leaks or damage at those connections due to vibrations. . It’s the same principle as using flexible connections at the inlet and outlet of many pumps and compressors
Thank you for the attention from 2# and 3#. The reason for doing this is to transmit pump vibrations to the process pipelines. The key question is: is there any basis for arranging the pipes in this way? Where can I find the basis for this? Thank you!
Is there a damper at the outlet of the plunger pump? And this is a plunger pump with how many cylinders. The design of high-pressure hoses is rare.
Expansion joints are installed at the pump’s inlet and outlet to reduce vibration

It is a 3-plunger 27MP pump whose hydraulic end has a damper (accumulator) added
