Description

"VIBRATORY PUMP IMPROVEMENT"

The present descriptive report is referred to a pioneer

patent for vibratory pump, related to the hydraulic equipment field, which

pump has been improved for being better adapted to tubular wells.

A vibratory pump is already known, substantially

comprised: by a frame; a solenoid housed in the lower part of the frame; by a

moving transmission member, axial to the frame, capable of axially oscilla

ting, an end of which is subject to the solenoid, the intermediate section of

which is assembled upon flexible support assembled in the frame and the

upper end subjects parts of a pumping device composed: of a membrane with

a central region assembled in the transmission member and periphery assem

bled amongst frame parts and with such defining an auxiliary pumping

chamber; such pumping device is still comprised of pumping outlets derived

from mentioned auxiliary pumping chamber; by cupping assembled in the

transmission member end, subject to the same and that operates in a commu

nication seat of such auxiliary pumping chamber with an upper admission

chamber; by system of opening and closing valves of the admission chamber

and subject to the cupping moving; amongst others.

This type of pump, in its usual construction, is purpo

sed to be used in regular wells. An inconvenience noted in such type of re

gular pump is concerned to the heating of the solenoid pump to undesirable levels. In order to solve such inconvenience several proposals have been ma

de, which, however, have not yet met all success intended.

Thus, the vibratory pump improvement's purpose,

object of the present pioneer patent, is providing a pump that could be

adapted to tubular well-

Other objective of the present improvement is

providing the pump with proper cooling means of the solenoid coil.

Another objective of the present improvement is

providing the pump with means such that make possible using it in many

ways, in order to comply with different requirements.

Having in view the hereinbefore mentioned problems,

and with the purpose of overcoming the same and aiming at fulfilling the

listed objectives, it has been developed the vibratory pump improvement,

object of the present pioneer patent, whose construction, operation and ad

vantages are hereinafter described, based upon the attached drawings, in

which:

igure 1 shows the pump both laterally and in section;

Figure 2 shows an accessory of the pump, purposed

adapting the same to be used as a suction pump; Figure 3 shows a detail of the pump by having adapte

bly of two pumps in series;

Figure 5 shows a detail of the pump by having adapted

the accessory of the previous figure; and

Figure 6 shows the pump into a version with frame -

made of plastic.

In compliance with the illustrations stated in the

figures hereinbelow listed, the vibratory pump, object of the present pioneer

patent, is addressed to the water pumping and it is comprised, in its essence,

of a set of frame 1; by a driving solenoid 10 housed in the frame; by a set of

moving transmission, composed of a member 20, axial to the frame, capable

of axially oscillating, an end of which has assembled a base 21 subject to the

driving solenoid 10, the intermediate section of said member 20 is assembled

upon flexible support block 22 and the opposite end of said member subject

to parts of the pumping set 30, formed by a set of oscillating cover 31 with

smaller base assembled in the member 20 and larger base that houses the su

pport block 22 and assembled amongst the fixed parts of the frame set 1; by

auxiliary pumping chamber 32 defined by said oscillating cover 31 and parts

of the frame set 1; by pumping outlets 33 derived from mentioned auxiliary pumping chamber 32; by cupping 34 assembled in the opposite end of the

transmission member 20, by seat 35, in which the cupping 34 operates and

that communicates said auxiliary pumping chamber 32 with an admission

chamber 36; and by system of valve of vane type 37 of opening and closing

of the admission chamber 36 inlets 38 and subject to pressure in the inner

part of the same provided by the cupping 34 moving; amongst others.

The present improvement, consists, essentially, of

providing the pump of diameter smaller than the diameter normally observed,

proper for housing the same inside the tubular well, to which purpose its

frame 1 and all mechanism have been radially reduced and compensated, so

as to be adapted to the tubular well and keeping the pump output within the

proper standards.

Another improvement consists in providing pump of

the driving solenoid set 10 cooling device, that comprises inverting the me

chanism position, so that mentioned solenoid 10 is located in the upper regi

on of the pump and housed within the inverted tubular cup 40; and the

transmission member 20, subject to the solenoid; and the pumping set 30,

subject to the transmission member 20; and the water intakes 38, are dispo

sed in the lower region of the pump; said inverted tubular cup 40 defines an

annular pass 41 in connection with the frame wall 1, whose upper end com

municates with the upper pumping outlet 2 of the frame 1 and the lower end of said pass 41 communicates with the pumping outlets 33 communicant

with the auxiliary pumping chamber 32 of the pumping set 30; said pass 41;

the circulating water in the same; the cup wall 40, that encloses the driving

solenoid 10 constitute mediums of heat exchange, that provides the driving

solenoid 10 cooling, in order to be possible to incorporate the improvement

hereinbelow mentioned, the pump's construction has been completely

reformulated, as more in details hereinafter described.

Thus, the frame set 1 is composed, essentially, of : an

external cylindrical frame 1 with external diameter selected to be received

inside the tubular well and provided with conical upper end, that ends in the

pumping outlet 2 and lower end that has assembled a nozzle 4 of the pump

accessories fitting. In the inner part of the external cylindrical frame 1 and by

keeping an space in connection with the same, which constitutes the pass 41,

it is foreseen the inverted cup 40, that houses the solenoid 10, which is cylin

drical and escalated and foresees a narrower upper section, in which it is as

sembled the end of the solenoid core 10 and wider lower section, extended by

the major part of the cup height, in which it is housed section of the core and

the coil winded in the same, that constitute the solenoid 10; below these it is

disposed the base 21 of the transmission member 20 subject to the solenoid

and under mentioned base 21 and around the transmission member 21 it is

foresee the pumping set 30, which besides its pumping function provides the

insulation amongst the wet and dry parts of the pump. The pumping set 30 it is housed into a set of cylindri

cal wall 40' assembled in continuation to the cup 40 upper end, which defi

nes a pair of upper backstops, between which are fastened a peripheral tur

ned edge of the upper base of the cover 31 and the seal ring of a seal set 39,

that still foresees an upper 0-ring, inserted between the base of the cover 31

and the set of wall 40'; in the intermediate region of said set of wall 40' are

foreseen the pumping outlets 33 radially placed and in the upper end, menti

oned set of wall 40' has assembled a first closing under substantial shape of

cup 40", whose upper end foresees an assembly flange slightly conical with

concave upper end, which defines the seat 35, in which the cupping 34 ope

rates and in continuation to such flange it is foreseen a cylindrical section,

that defines the admission chamber 36, in whose bottom are foreseen the

water intakes 38 and is assembled the vane valve 37, that controls the latter;

under mentioned first closing in shape of external cup 40" it is foreseen a

second closing in the shape of external cup 40'" provided with turned edge

of upper assembly placed under the flange of the first closing 40" and whose

bottom is projected outside the nozzle 4 of the accessories fitting, supports

the first closing 40" and foresees holes of water intake 38', lined up with

holes 38 of the admission chamber 36; the mentioned first 40" and second

40'" closings are assembled so as they can be disassembled by means of de

vice that includes radial tightening devices 5.

The core 11 of the solenoid 10 is cylindrical and fore sees a lower diametrical crack, which defines double-split section extended

for almost all core height and where the coil 12 is winded with enameled vvi

re; the core base, of laying in the upper narrow section of the cup 40, does

not foresee the crack and is proyided with through axial hole, in which it is

located the coil's electric feeding cable 13, which is extended outside of the

bottom of .cup 4.0 and .of the .upper conipal wall of the external frame 1 , so as

not be located beyond the projection of the external frame 1 perimeter and

thus making easy the pump installation in .tubular well. The base 21 of the

ansmission member 20, that is subject to i ^ solenoid 1.0, is also cylindrical

and composed of an aggregate of material subject to magnetic attraction and

is fastened to the member 20 by means of pins, welding and aluminum.

The pump, constructed as hereinbefore described, has

three diverse ways of use. In one of the possibilities, (Figure 1) the pump is

used without the auxiliary .accessories, assembled in the middle .of the tubular

well and the water collection is directly made by the inlet openings 38, 38'.

in other possibility, the pump receives in its nozzle 4

.of .accessories fitting .a base 5.0 (Figures 3 and 4) to be used supported in the

base as a suction pump. The base 50 is a tubular body comprised by a cou

pling -cylindrical upper section 51 in the nozzle 4 of the pump .and by a coni

cal-tubular trunk lower section 52, which is extended and widened as from

that, of support in the bottom of the well .and provided with a water intakes

53 lining up, placed close to the upper end of the mentioned conical-tubular trunk section 52.

In another possibility' of use, the pump receives a

coupling 60 nozzle 4 (Figures 4 and 5), purposed to connect the pump inlet

to the outlet of a second pump, in order to assemble various pumps in series

vertically placed, for reaching biggest depths or horizontally placed for pres

surization of the pumping lines. The coupling 60 is a tubular body comprised

by a coupling cylindrical end 61 in the pump nozzle 4, intermediate conical

section 62 and cylindrical extreme section of lower diameter 63 of receiving

and fastening of the connection nipple (64) to a pump outlet. In this way of

use, at least the pumps following to the last upstream pump, receive external

belts made of rubber-type material 70, purposed to fasten the main electrical

feeding cable 13', from which are derived the cables 13 that reach the

pumps.

In this way, the pump, object of the present pioneer

patent, can be properly applied in tubular well, by taking into account that

has dimensioning proper to such purpose, without however have its efficien

cy reduced.

The cooling device of the present pump, as

hereinbefore conceived and described, solves in proper way the solenoid-

heating problem, by improving both the pump output and useful life.

And, yet, the possibility of connecting the pump to

different accessories will make possible a wide flexibility' of its use, by more completely fulfilling the requirements of the consumer market.

Within the basic conception hereinbefore described, it

is being pled the possibility of presenting the pump, object of this pioneer

patent, changes relating to materials, dimensions and constmctive details

without leaving the sphere of the requested protection. For this purpose, the

pump might have its frame made of stainless steel or aluminum (Figures 1 to

5) or of engineering plastic (Figure 6), solutions which are substantially

preserving the same characteristics, yet incorporating only some constmctive

differences, however related to the possibilities of arrangements resulting

from the materials utilized in its construction. Thus, the pump with plastic

frame has substantially the same construction of that one made of steel or

aluminum, except that foresees a second lower closing 40'", which

corresponds to the second closing 40" of the other version, comprised by a

cup that is coupled to nozzle 4, whose bottom has grate shape and supports

the valve 37' admission chamber 36' and is able to receive accessory for

connection to the second pump inlet.

The pump, object of the present pioneer patent, is to

be used in the field of the hydraulic installations, particularly those purposed

to water pumping, preferably water pumping from tubular well and is yet

used for pressurization of pumping lines.
