Liquid Ring Vacuum Pump Design Code

Defines the minimum requirements for the basic design inspection testing and preparation for shipment of liquid ring vacuum pump and compressor systems for service in the petroleum chemical and gas industries.

Liquid ring vacuum pump design code. Pump designed to remove gases through the use of rotating impeller blades that enter and leave a ring of liquid. The design of the system is critical to the successful operation of the liquid ring vacuum pump or compressor. The technology behind liquid ring vacuum pumps. Api std 681 liquid ring vacuum pumps and compressors for petroleum chemical and gas industry services.

How liquid ring pumps work and what devices are used to control the operation of a liquid ring pump system for proper operation designing steam jet vacuum systems open file 220 12 kb description. Steam jet vacuum systems combine ejectors condensers and interconnecting piping to provide relatively low cost and low maintenance. This includes both vacuum pump and compressor design and system design. Liquid ring vacuum pumps.

For more than 110 years nash liquid ring technology has provided reliable solutions for process applications. Sihi single stage or two stage design for handling of gases and vapours. In this design the cells between the impeller rotor blades are open around the periphery. The following figure shows construction of a typical cone type vacuum pump.

Close attention must be paid not only to the design of the ring liquid system but also to how it is integrated into the user s process. Find out how the nash liquid ring vacuum pump w. The klrc is a non pulsating vacuum. Through our ongoing commitment to innovation product research and development nash continues to.

33 up to 1013 mbar. Cone type and flat plate type. Liquid ring vacuum pumps are designed in two different types. They are typically used as a vacuum pump but can also be used as a gas compressor the function of a liquid ring pump is similar to a rotary vane pump with the difference being that the vanes are an integral part of the rotor and churn a rotating ring of liquid to form the compression chamber seal.

Kinney liquid ring vacuum pumps and systems. A liquid ring pump is a rotating positive displacement pump. The design technology behind liquid ring vacuum pumps is advanced to achieve optimum reliable performance for the rigorous demands of harsh industrial environments. The impeller forces this sealing liquid to the periphery of the pump casing where it forms a moving ring of liquid.

Up to 10 700 m h suction pressure.
