Liquid Ring Pump Impeller

Liquid ring pumps have been designed for transferring and handling clean fluids and fluids without any suspended solid particles.

Liquid ring pump impeller.

Liquid ring vacuum pumps and systems. Liquid ring vacuum pump consists of pump cover pump body disc impeller mechanical seal motor and other parts. Based on the actual operating cycle of suction compression discharge expansion a universal theoretical model for performance of liquid ring pump was established in this study to solve the problem that the theoretical models deviated. The intake pipe and exhaust pipe are connected with the pump cavity through the suction hole and exhaust hole on the disk installed on the pump cover.

Liquid ring pump is widely applied in many industry fields due to the advantages of isothermal compression process simple structure and liquid sealing. The klrc is a non pulsating vacuum. Pump designed to remove gases through the use of rotating impeller blades that enter and leave a ring of liquid. Liquid ring pumps are available in single and dual stage designs and also configured as compressors for even more versatility.

The pump impeller is mounted eccentrically to the axis of the pump casing when the impeller is rotated at the appropriate speed and a supply of liquid is introduced into the pump chamber the liquid ring is created concentrically to the pump casing. As the impeller rotates a chamber is formed by the impeller blades and the inside of the liquid. The impeller forces this sealing liquid to the periphery of the pump casing where it forms a moving ring of liquid around a center void. This feature makes the fzx more efficient for complete evacuation of tanks and lines during normal process or cip.

This kind of self priming reversible pump can work with a wide range of products and fields such as the wine and oil industries wines must vinegar and olive oil dairy products industry milk whey etc and chemical industry acids solvents detergents. 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. By using a specially designed impeller and housing the fzx maintains its prime when other pumps become air bound. The space in the cells is largest at the lower vertex as these cells are virtually free of operating liquid.

The seal liquid forms the ring inside a pump body as the impeller spins creating small chambers for gas to be trapped.
