Benefits of technology

"The present invention provides a pumping system that uses a diaphragm pump and a pressure intensifier to increase the pressure of the driving fluid and generate pumping strokes that produce a higher output pressure than the supply pressure. The pressure intensifier is preferably a two times intensifier, and the pump has a 1:1 input to output pressure ratio. The pressure intensifier can be incorporated into the diaphragm pump or a spool valve controlling the supply of drive fluid to the diaphragms. The technical effect of this invention is to provide a more powerful and efficient pumping system for various applications."

Problems solved by technology

However, although such diaphragm pumps are significantly larger and more expensive to produce than are pumps which have a 1:1 ratio, their use in systems in accordance with the present invention is not excluded.

Embodiment Construction

[0014] Referring to the drawings, FIGS. 1, 2 and 3 illustrate a known form of diaphragm pump in which a generally cylindrical central metal body 11 has an axial through bore 12 and is fitted, at its opposite ends respectively, with first and second end plates 13, 14. The face of the body 11 presented to the end plate 13 is concave, and the face of the end plate 13 presented towards the body 11 is also concave. The concavities of the end plate 13 and body 11 define an internal chamber which is divided into a drive chamber 15 and a pumping chamber 16 by a flexible metal diaphragm 17 having its periphery trapped between peripheral regions of the end plate 13 and the body 11. The arrangement at the opposite axial end of the body 11 is similar in that an internal chamber is divided into a drive chamber 15a and a pumping chamber 16a by means of a diaphragm 17a. A link rod 18 is slidably received in the bore 12 of the body and is connected at its opposite axial ends respectively to the dia...

Abstract

A pumping system incorporating a diaphragm pump and in association therewith a pressure intensifier receiving pressurised driving fluid from a supply, said intensifier boosting the pressure of the drive fluid beyond its supply pressure and supplying the drive fluid, at said increased pressure, to said diaphragm pump, to generate pumping strokes of the pump producing a pump output pressure in excess of the drive fluid supply pressure.

Description

TECHNICAL FIELD [0001] This invention relates to a pumping system incorporating a diaphragm pump, particularly but not exclusively for supplying liquid paint to a paint spraying system. BACKGROUND ART [0002] Diaphragm pumps are well known and generally comprise a pumping chamber bounded in part by a moveable diaphragm, the diaphragm being moveable by the application of fluid under pressure to reduce the volume of the pumping chamber and so expel fluid, usually liquid, from the pumping chamber. Generally diaphragm pumps are constructed as double-acting pumps in that there are two pumping chambers each having an associated diaphragm, the two diaphragms being physically interconnected so that when one is moving to reduce the size of its pumping chamber to expel fluid from the pumping chamber the opposite diaphragm is moving in a direction to increase the volume of the pumping chamber and so draw fluid from a fluid supply into the pumping chamber. It is to be understood however that in ...
