Description
Technical field
This utility model relates to axial-flow pump technical field, more particularly, it relates to a kind of axial-flow pump bend pipe structure.
Background technology
Axial-flow pump is the pump that the active force that liquid produces is made liquid carry in the axial direction by the blade by spinning roller impeller.The impeller of common axial-flow pump includes following several parts: impeller boss, 2～7 blades being arranged on impeller boss, is arranged on the movable vane head of impeller boss end.Impeller boss, blade and movable vane head collectively constitute impeller.Impeller rotates in tubular pump case.Equipped with fixed guide vane on the pump case of upper impeller, in order to eliminate the rotary motion of liquid, so as to become axially-movable, and the kinetic energy of rotary motion is changed into pressure energy.Axial-flow pump is absorbed water by the water-inlet horn of bottom, is axially exported via Discharging bent-tube by water after being carried by impeller.Discharging bent-tube is for changing the outbound course of water so that the water outlet of axial-flow pump can carry out along desired direction.
In use, its water outlet end can arrange bend pipe structure to existing axial-flow pump, thus water outlet direction is adjusted.And the bend pipe arranged its only have adjustment effect, and not there is observation effect so that operator can not understand the ruuning situation of axial-flow pump in time.And it is not provided with filtration, it is impossible to stop the impurity in trickle.
Accordingly, because prior art exists above-mentioned technological deficiency, it is those skilled in that art's technical problems urgently to be resolved hurrily.
Utility model content
The purpose of this utility model is for providing a kind of axial-flow pump bend pipe structure, it is intended to the bend pipe structure solving to exist in prior art is simple, the problem without overview function and filtering function.
For achieving the above object, this utility model provides following technical scheme:
A kind of axial-flow pump bend pipe structure, including bend pipe, extra heavy pipe, water inlet, outlet, first flange, second flange, glass vision panel, groove and drainage screen, described bend pipe connects extra heavy pipe, described extra heavy pipe diameter is the twice of described bend pipe diameter, described bend pipe end is water inlet, described extra heavy pipe end is outlet, described water inlet is provided with the first flange, described outlet is provided with the second flange, described elbow sidewall is provided with glass vision panel, it is provided with groove in the middle part of described second flange, described groove is toroidal cavity, described groove diameter is more than described extra heavy pipe diameter, it is provided with drainage screen in described groove.
Preferably, also including brace rod, described brace rod is located on rear side of described first flange and between described elbow sidewall, described brace rod is for being welded and fixed.
Preferably, also being provided with described brace rod between described second flange and described extra heavy pipe, described brace rod is for being welded and fixed.
Of the present utility model have the beneficial effect that by bend pipe connect extra heavy pipe such that it is able to when liquid is discharged, reduce its flow velocity, and the second flange in extra heavy pipe end be provided with drainage screen such that it is able to on axial-flow pump outflow liquid be filtered remove impurity；And on bend pipe, it being provided with glass vision panel, it is possible to the liquid observing axial-flow pump in time flows out situation, thus judging the operation conditions of axial-flow pump；The brace rod arranged, it is possible to strengthen the mechanical performance between the first flange and bend pipe or the second flange and extra heavy pipe, extend its service life.This utility model simple in construction, convenient observation, there is filtering function, mechanical strength is high, long service life.
