Definitions

  • the present invention relates to positive displacement positive displacement pumps or vacuum compressors of the type defined in the preamble to the main claim.
  • FR-A-1 503 605 a pump of this type is described.
  • the dead volume is important.
  • several unit pumps are mounted in parallel, the suction compartments, on the one hand, and the discharge compartments, on the other hand, communicating with each other and the means for bringing the membranes together being out of phase in the time from one unit pump to another.
  • the pump according to the invention which is self-priming, generally applies to the transport by pumping of a fluid at high flow rate, in a duct which can have a small diameter, while consuming little d 'energy and without the material subjected to pumping is mistreated, and while remaining very reliable in operation even in the event of a ram cup.
  • the invention aims to reduce the dead volume of a pump of this type.
  • Figures 1 and 2 are two diagrams, seen in section, illustrating the operation of a pump according to the invention.
  • the pump comprises a metal casing 1, of generally parallelepiped shape.
  • a suction tubing 2 In the casing 1, open a suction tubing 2 and a delivery tubing 3.
  • 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. On these walls is fixed a valve (16) and (16B), held by a cup 14 and 14B.
  • the bulkhead assembly A membrane 7, valve 16 and cup 14
  • the bulkhead assembly B membrane 7B, valve 16B and cup 14B
  • the walls 12 and 12B have no connection between them, they are simply secured by the fasteners 10 of the casing 1.
  • valve 16 is located in the intermediate chamber 6 and for the partition B, the valve 16B is located in the discharge compartment 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 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.
