Abstract
The invention is a double-casing volute pump, comprising a pump body, where a spiral extruding chamber is arranged in the pump body and connected with a spiral flow channel, the upper side of the flow channel is provided with an inward-projecting spacing tongue, the middle of the flow channel is provided with a baffle in the axial direction of the flow channel, the baffle extends spirally into the extruding chamber, a vane is arranged in the extruding chamber, the connecting line of the bottom end point of the baffle and the rotating center of the vane makes an included angle of 160-180 deg. with that of the spacing tongue and the rotating center of the vane; a first cavity forms between the baffle and the vanes, a second cavity forms between the vanes and the pump casing, and the two cavities are symmetrical with respect to the rotating center of the vanes. And it makes the pressures on two sides of the vane balanced all the time, able to largely reduce radial force and prolong the service life.
Description
Technical field
The present invention relates to mechanical field, relate in particular to fluid varactor machine, particularly pump, concrete is a kind of double volute pump.
Background technique
In the prior art, volute pump is used widely because of having the characteristics that flow is big, lift is high.Traditional single volute pump adopts the spirality delivery chamber, the spirality delivery chamber is by the design discharge design, and when being in Design Theory work, the speed and the pressure of the liquid around the impeller are uniform, axisymmetric, therefore acting on making a concerted effort on the impeller is zero, does not have the effect of radial force in theory.But because the spirality delivery chamber has dissymmetrical structure, when water pump operation off-design operating mode, then destroyed the condition that pressure is symmetrically distributed along impeller shaft, thereby produced radial force, the radial force that is produced mainly relies on bearing to bear, will cause the bearing wear aggravation like this, have a strong impact on the working life of volute pump.
Summary of the invention
The purpose of this invention is to provide a kind of double volute pump, described this double volute pump will solve the technical problem that single volute pump impeller shaft radial force causes bearing wear to aggravate in the prior art.
This double volute pump of the present invention is made of a pump housing, be provided with a spirality delivery chamber in the described pump housing, described delivery chamber is connected with spiral flow channel, the upside of described runner has one to the projecting inward cut water of runner, wherein, the longshore current road, middle part of described runner axially be provided with a dividing plate, described dividing plate extends in described delivery chamber with zigzag shape, be provided with blade in the described delivery chamber, the angle of the line between line between the lower extreme point of described dividing plate and the blade rotating center and described cut water and the blade rotating center is between 160～180 degree.
Further, form first cavity between described dividing plate and the blade, form second cavity between described blade and the pump housing inner walls, described first cavity and second cavity are about the rotating center symmetry of blade.
The present invention and prior art compare, and its effect is actively with tangible.The present invention utilizes dividing plate that the delivery chamber of blade both sides has been divided into the first symmetrical cavity and second cavity, makes the pressure balance all the time of blade both sides can significantly reduce radial force, prolongs the working life of pump.
Description of drawings
Fig. 1 is the structural representation of double volute pump of the present invention.
Embodiment
