Horizontal pumping systmes - high pressur einjector or pipeline booster in the new high-intake pressure application

摘要

Horizontal Pumping System (HPS) is a surface application of a Multistage Centrifugal Pump originally designed for submersible service. HPS's are highly flexible in operation. Suction pressures can vary from 50 to 2500 PSi and the standard design discharge pressure can be up to 5000PSI. Variable flow rates can be achieved with a flow control valve without changing the operating speed, which eliminates the expensive Variable Speed Controller, Re-circulation lines and isolation valves are not required so the required piping is very simple compared to Positive Displacement (PD) pump installations. Unlike PD pumps. HPS can be deadheaded for a short time without damage. If a line plugs or a valve closes there is little danger of having the line or pump burst. HPS can be started against full system back pressure or with no back pressure at all. HPS's operate very quietly with very low line vibrations, as the HPS's are not generating lfuid pulsation typical to PD installations.It can be easily designed as a Zero Emission system for operation in hazardous fluids with double seals with blocking fluids and control systems to ensure tha tthe produced fluid will not escape to the environemnt. PLC can be easily tied into the HPS to control flow, pressure, tank level, speed, etc. Units can be run in parallel or series configuration.Heavy foundations are not required and it can configuration. Heavy foundations are not required and it can be used as a portable unit. There is a significant reduction in maintenance cost, as there is little field maintenance required. Pump repair time can be as little as one day. Modular components allow for easy field retrofit. Due to the simple design of HPS, it can be operated remotely.
