Abstract
The utility model discloses a disc pump, comprising a disc impeller, which is characterized in that a pumping chamber is annular and the axes of the pump chamber and the impeller are collinear. The beneficial effect of the utility model: proved by tests that the pumping efficiency of the disc pump can be improved greatly and the wear between the impeller and the pumping chamber is reduced and the service life of the disc pump is lengthened by limiting the shape, the size of the pumping chamber of the disc pump and the installation site position of the impeller in the pumping chamber.
Description
Technical field
The utility model relates to a kind of water pump, is a kind of disk pump of boundary layer flow effect and structure of pumping chamber thereof utilized specifically.
Background technique
Existing FLUID TRANSPORTATION pump mostly is centrifugal pump, its blade wheel structure has two kinds of double shrouded wheel and unshrouded impellers, but the subject matter of existing FLUID TRANSPORTATION is that material must contact with impeller, cause damage in impeller big, and cavitation phenomenons is serious, causes when containing the high solid particle of hardness in the pump case of centrifugal pump and the impeller surface heavy wear, particularly material, this phenomenon is more outstanding, causes the material efficient of transfer of highly viscous, high concentration lower.
Water pump pumping chamber structure rationally whether bigger to the pump performance influence.If adopt annular pumping chamber, each cross-sectional area of longshore current road equates that mixed solution is mobile inhomogeneous in the annular pumping chamber, and flow velocity is become greatly gradually by the cut water Way out, and hydraulic loss is big, and the efficient of pump is reduced, and wastes energy.Therefore, traditional water pump all adopts involute pumping chamber or helix pumping chamber to improve the efficient of pump.
The disk pump is a kind of pump that utilizes boundary layer laminar flow effect to carry high concentration, high viscosity, high hardness material.At the Chinese utility model patent specification of bulletin on October 13rd, 2004, describe in the notification number " CN 2648129Y ".Exist the not high problem of liquid efficient of carrying in disk pump and the involute pumping chamber fit applications, and in course of conveying, liquid pressure is higher between impeller outer edge and pumping chamber inwall, the high concentration liquid that causes easily carrying leaks into the impeller outside, because the stickiness of high concentration liquid is bigger, therefore greatly increased between the impeller outside and pumping chamber and worn and torn, obviously reduced efficient.
Summary of the invention
The purpose of this utility model is: provide a kind of efficient higher, the disk pump that the life-span is long.
The technical solution of the utility model is:
A kind of disk pump includes the plate-like impeller, it is characterized in that, its pumping chamber is an annular, and the axis of the axis of annular pumping chamber and impeller is on the same straight line.
According to the described disk pump of claim 1, it is characterized in that the ratio of annular pumping chamber diameter and impeller diameter is 1.04-1.35.
The beneficial effects of the utility model are: by shape, size and the impeller mounting point in pumping chamber of rational qualification disk water-pumping chamber, through experimental results show that the efficient that can obviously improve the disk pump, reduce the wearing and tearing of impeller and pumping chamber, prolonged the life-span of disk pump.
Description of drawings
Fig. 1 is a schematic representation of the present utility model.
Wherein, reference character: 1 is pumping chamber, and 2 is impeller, and 3 is suction port, and 4 is exhaust port.
Embodiment
Below in conjunction with drawings and Examples the utility model is further specified.
Specific embodiment of the utility model, as shown in Figure 1, a kind of disk pump, include plate-like impeller 2, pumping chamber 1 and be positioned at the suction port 3 of pumping chamber 1 side and be positioned at the exhaust port 4 of pumping chamber 1 outer rim, it is characterized in that: its pumping chamber 1 is annular, and the axis of the axis of annular pumping chamber 1 and impeller 2 is on the same straight line.
Adopt annular pumping chamber can obtain the efficient higher through experimental results show that than involute pumping chamber.
Again owing to liquid pressure between impeller 2 outer rims and pumping chamber 1 inwall is higher, the high concentration liquid that causes easily carrying leaks into impeller 2 outsides, because the stickiness of high concentration liquid is bigger, therefore greatly increased impeller 2 outsides and 1 wearing and tearing of pumping chamber, obviously reduced efficient; And the distance of 1 of impeller 2 and pumping chamber is excessive, also can cause flow losses to increase, and therefore the distance that rationally limits between impeller and the pumping chamber can reduce wearing and tearing, improves the efficient of pump.
Recording through experiment, the ratio of annular pumping chamber 1 diameter and impeller 2 diameters can obtain efficient preferably during for 1.04-1.35, alleviates wearing and tearing, improves the life-span of pump.
Claims (2)
1. disk pump, include plate-like impeller (2), pumping chamber (1) and be positioned at the suction port (3) of pumping chamber (1) side and be positioned at the exhaust port (4) of pumping chamber (1) outer rim, it is characterized in that: its pumping chamber (1) is annular, and the axis of the axis of annular pumping chamber (1) and impeller (2) is on the same straight line.
2. according to the described disk pump of claim 1, it is characterized in that the ratio of annular pumping chamber (1) diameter and impeller (2) diameter is 1.04-1.35.
