Abstract
The invention belongs to the efficient liquid feedway.
This device is that the conical pump housing two parts are formed by conical spiral shaft and inner cavity.Screw axis is made of around the spiral plate that axle connects continuously an axle and a few circle.Spiral plate outer surface on the screw axis is identical with the cone angle of pump housing inner cavity.When screw axis placed in the pump housing, the adjustable gaps between screw axis and pump housing conical surface was to minimum, and liquid can not produce tangible axial leakage by the gap between the conical surface.When screw axis rotated, the liquid in the spiral axial trough can be all promoted to move vertically by screw inclined plane, and it is outer and no liquid is detained in the pump to be transferred out pump, thereby realized that efficient liquid carries.
Description
The invention belongs to the efficient liquid feedway.
Volume the versions in 1984 " mechanical technique handbook " that clear from China's " China Machine Press " translation " Japanese mechanology meeting " and " mechanical engineering brief guide " that changed in 50 years publishes, the 9th piece of 9-22 page or leaf, 372, recognize among the C " helical type pump " that " helical type pump " is to cut out spiral chute on running shaft, axle is rotated in the axle sleeve of this cooperation, realize the effect of pump.The running shaft of this device and axle sleeve are cylindrical, and its matching gap is fixed.
It is whole to minimum to the purpose of this invention is to provide between a kind of conveyor member and the pump housing adjustable gaps.In course of conveying, liquid can not produce by the gap and obviously leak the efficient feedway that is detained in the pump.
This device is that the conical pump housing (hereinafter to be referred as the pump housing) is formed by tapered auger axle (hereinafter to be referred as screw axis) and inner cavity mainly.As shown in drawings, screw axis (1) is made of around the spiral plate that axle connects continuously an axle and a few circle.Spiral plate outer surface on the screw axis (1) and the pump housing (2) inner cavity are the taper shape of identical cone angle.When screw axis (1) placed the pump housing (2) inner chamber, the adjustable gaps between the screw axis (1) and the pump housing (2) conical surface was whole to minimum.Make the liquid in screw axis (1) groove not produce tangible axial leakage, and be detained in the pump by gap between the conical surface.When screw axis (1) rotated, the liquid in the spiral chute was all promoted to move vertically by the spiral plate inclined-plane, and is transferred out outside the pump, thereby realized the efficient conveying of liquid.
Because adjustable gaps is to minimum between the screw axis and the pump housing conical surface, liquid does not produce tangible axial leakage, and the liquid that enters in the pump all is transferred out pump, and does not produce conveyance loss.Except that bearing friction loss, this device does not almost have other useless power consumption, thereby realizes the efficient liquid conveying.For carrying the various liquid that do not contain solid particle, the centrifugal infusion pump efficient that this device is commonly used at present exceeds about 20%.Remarkable energy saving effect is arranged.
Claims (6)
1, a kind of efficient liquid feedway.Feature of the present invention is that spiral plate outer surface and the associated pump housing inner cavity on the screw axis is the identical taper shape of cone angle, and adjustable gaps is to minimum between the screw axis and the pump housing conical surface, and liquid can not produce tangible axial leakage by the gap between the conical surface.When screw axis rotated, the liquid in spiral chute can all be transferred out outside the pump, and no liquid is detained in the pump, thereby realized the efficient conveying of liquid.
2, according to claim 1, described device is characterized in that the spiral plate outer surface cone angle on the conical spiral shaft is identical with the cone angle of pump housing inner cavity.Cone angle can for greater than 0 ° less than any angle in 45 ° of scopes.
3, according to claim 1, described device is characterized in that the rotation direction of the spiral plate on the conical spiral shaft, can be left-handed or dextrorotation.
4, according to claim 1,3 described devices is characterized in that the lead angle of spiral plate can be for greater than 0 ° of arbitrarily angled less than in 45 ° of scopes.
5, device according to claim 1 is characterized in that spiral plate can be single head or bull on the conical spiral shaft.
6, device according to claim 1 is characterized in that screw axis and pump housing available metal material or nonmetallic material manufacturing.
