Definitions

the present invention relates to positive displacement positive displacement pumps or vacuum compressors.
the pump according to the invention which is self-priming, applies, in general, to the transport by pumping of a fluid at high flow rate, in a conduit which may have a small diameter, while consuming little d energy and without the material subjected to pumping being abused, and while remaining highly reliable in operation even in the event of water hammer.
the subject of the invention is therefore a pump formed of a sealed envelope having a suction pipe and a delivery pipe, of two membrane walls and seat, inside the envelope, which delimit between them a compartment.
a pump formed of a sealed envelope having a suction pipe and a delivery pipe, of two membrane walls and seat, inside the envelope, which delimit between them a compartment.
intermediate between two suction and discharge compartments communicating respectively with the pipes and which allow the passage of a fluid only from the suction compartment to the intermediate one and only from the latter to the discharge compartment, and means for alternately move the walls apart and bring them closer together, characterized in that a membrane is locally retained at its seat.
the flow of the fluid is not interrupted.
the suction and discharge pipes unlike known positive displacement pumps, open freely in their compartment and are not provided with any fluid retention system. This saves a lot on the power consumed for the operation of the pump.
the seat is rigid and the membrane is retained at the seat. The membrane then serves both as a valve and as a member for modifying the volume of the intermediate compartment.
the seat comprises a rigid grid, on the periphery of which is fixed an elastic skirt whose outer periphery is fixed to the envelope. It is then the skirt which serves as said organ.
Figures 1 and 2 are two diagrams, seen in section, illustrating the operation of a pump according to the invention.
Figure 3 is a diagram of another variant.
Figure 4 is a top view of the mem brane, fixed at two points, of the variant of FIG. 4.
the pump comprises a metal casing 1, of generally parallelepiped shape.
the interior of the casing 1 is subdivided into three compartments, one 4, suction, where the tubing 2 opens, another 5, discharge, or the tubing 3 opens and a third 6, intermediate by two walls A and B suction and discharge.
Each partition comprises a waterproof membrane or skirt 7 and 7B fixed at 10 around the periphery of the envelope 1.
the membrane 7 is connected by a grid 11 forming a seat to a wall 12 and the membrane 7B to a wall 12B by a grid of the same type. These walls 12 and 12B are provided with an opening.
the bulkhead assembly A (membrane 7, valve 16 and cup 14) is integral with a rod 15 and the bulkhead assembly B (membrane 7B, valve 16B and cup 14B) is integral with a rod 15B.
compartments 4, 6 and 5 the walls 12 and 12B have no connection between them, they are simply joined together by the fasteners 10 of the envelope 1.
valve 16 is located in the intermediate chamber 6 and for the partition B, the valve 16B is located in the discharge chamber 5.
the rods 15 and 15B pass through the casing 1 via a flexible element 18 and 18B.
the flexible element 18 is integral with the envelope 1 and the rod 15 and the flexible element 18B of the envelope 1 and the rod 15B.
a recess 17 of the envelope is provided between the points 10 for fixing the membranes 7 and 7B, so as to reduce the volume of the compartment 6 comprised between these two membranes when they are brought together.
the rods 15 and 15B are driven in an alternating movement by a motor 19.
the device operates in the following manner: the two walls are driven in an alternating movement in opposition.
the vacuum in compartment 4 increases.
the fluid of the tubing 2 is thus sucked towards the compartment 4.
the fluid in compartment 5 is thus discharged towards the discharge pipe 3.
the seats 20 come from the casing 1. On these seats apply membranes 21, 22 secured to the pistons 15 and 15B and retained at two points 23, 24 diametrically opposite their seats 20.
the two points 23, 24 also make it possible to ensure the guiding of the piston 15 and facilitate obtaining the seal upon closing.
