Description
Technical field
The invention belongs to a kind of pump configuration more particularly to a kind of jet pump structures.
Background technology
Jet pump feature is so that impeller 2 is generated centrifugal force by 1 wheel rotor 2 of main shaft as shown in Figure 1, promotes liquid from water pump
The process that import A is moved to exit of pump B, the conveyed liquid of pump are entered in impeller 2 through jet pipe 10 by unit fixed on water pump suction A,
Centrifugal force through motor drive main shaft 1 accelerates pressurized flow.
Liquid, through deflector water conservancy diversion, enters in pump chamber 7 that (pump chamber 7 is by being arranged from the hole of deflector after the outflow of impeller 2
The 0 type sealing ring 11 on jet pipe 10 obtains sealing), then flow out exit of pump B.
Under the effect of the pressure, partially liq enters in nozzle 12 exit of pump B, and (liquid is defeated for the outlet height of water outlet B
Pressurization pressure) it is bigger, bigger to the pressure of pump chamber 7 reaction force to nozzle 12, pressure increases, and the flow velocity of nozzle 12 pushes jet pipe
Flow velocity enhances shown in the arrow of 10 pump inlet A, to increase pump lift and vacuum pressure (suction).
However just because wanting lossy when fluid is converted into axial jet motion from radial centrifugal movement in the course of injection,
Material deformation etc. can generate interior leakage loss in the conversion of baffle compression direction, therefore realize that correct water conservancy diversion is that jet pump improves efficiency
Key, baffle be exactly jet pump reliability quality efficiency promoted core component.
It is complex-shaped at present because the structure of jet pump baffle is all integral type, it is multiple that it can only be completed with plastic injection
Miscellaneous structure, plastic products have its soft change and interior leakage caused by compressive deformation, are always that the injection efficiency of pump is low, poor reliability main
Reason.
