Description

1 Claim.
My invention relates to pumps, particularly the suction pipe thereof, and has among its objects and advantages the provision of an improved water inlet device operating to eliminate agitation of the water at the well bottom so as to preclude the entry of sand and the like into the suction pipe.
In the accompanying drawing:
Figure 1 is an elevational view;
Figure 2 is a longitudinal sectional View; and
Figure 3 is a transverse sectional view along the line 3-3 of Figure 2.
In the embodiment selected for illustration, I
make use of a tubular member l0 having a neck I2 provided with a threaded opening Hl for threaded connection with the bottom end of the suction pipe I6 of the pump (not shown). Member I is somewhat larger in diameter than the neck i2, and the neck is bent so as to bring the axis of the member I0 coincident with the axis of the pipe I6.
Neck I2 is narrowed at i3 so that one side of the member IB projects beyond this wall of the neck substantially half its diameter, and this end of the projection is provided with an inlet opening 20. This opening is covered by a grill or strainer 22 arranged at an angle of about forty-five degrees to the aXis of the member IB. A partition 24 is provided inside the member l@ to divide the member into passages 2S and 2S. The partition terminates short of the closed end 3 of the member l0 so that water flowing downwardly in the passage 26 may reverse its ow as it passes underneath the partition 24 and upwardly into the suction pipe i6.
In operation, the invention prevents the entry of sand into the suction pipe l5 in that the well water remains undisturbed at the bottom of the well. The inlet opening is located near the upper end of the member iii and water entering the member ows downwardly so as to eliminate water disturbances close to the well bottom. Water is caused to flow downwardly as it enters the opening 2@ which eliminates disturbances peculiar to upward movement of water close to the well bottom, as is peculiar to ordinary openended suction pipes. The grill 22 prevents large objects from being blown into the member i il.
Without further elaboration, the foregoing will so fully illustrate my invention, that others may,
by applying current knowledge, readily adapt the same for use under Various conditions of service.
I claim:
A sand eliminator i'or connection with the water inlet end of a pump suction pipe comprising a one piece tubular member closed at its bottom end and having a connection at its upper end for attachment to the pump suction pipe, said tubular member having a neck constrcted at one side to project approximately half the diameter of said member laterally of said neck, said member being provided with a partition constituting a continuation of one side of said neck at the oonstricted side thereof to divide the member into a downwardly flowing passage and an upwardly flowing passage, the portion of the member projecting beyond said neck having an inlet opening in its upper end, and a grill extending across said inlet opening.
