Abstract
The utility model discloses a constant-pressure tangent pump which is characterized by comprising a base (11), a pump body (1) and a driving motor (12). The pump body (1) is mounted on the base and is provided with an impeller operating chamber, the impeller operating chamber is defined by a shell, an impeller (4) is arranged in the impeller operating chamber, a shaft of the impeller is rotatably and horizontally mounted on a pump cover (10) which can close the impeller operating chamber, a mechanical seal (9) is arranged between the shaft and the pump cover, the impeller operating chamber is provided with an inlet end and an outlet end, the inlet end is communicated with the impeller operating chamber and is arranged horizontally, the outlet end is communicated with the impeller operating chamber and is arranged vertically, and a drainage cavity is arranged on the lower portion of the impeller operating chamber and is provided with a drainage cock (2); the driving motor (12) is mounted on the base, and a power output shaft of the driving motor (12) is connected with the impeller (4) of the pump body. The constant-pressure tangent pump has the advantages that the pressure of the pump keeps constant under the condition that water current changes, and the constant-pressure tangent pump is simple in structure, low in cost and high in work efficiency.
Description
Technical field
The utility model relates to a kind of constant voltage tangent pump.
Background technique
For now, common pump can't satisfy can guarantee under the operating mode of unsteady flow amount that pressure changes and fluctuate that the pump that can satisfy this requirement is structurally comparatively complicated usually, and working efficiency is lower in small range.
Summary of the invention
The purpose of this utility model is exactly in order to address the above problem, and a kind of constant voltage tangent pump is provided.
To achieve these goals, the utility model adopts following technological scheme:
A kind of constant voltage tangent pump is characterized in that, comprising:
Base (11);
Be installed on the pump housing (1) of base, it has the impeller working room that is limited by housing, be positioned at this impeller working room and be provided with impeller (4), the axle of described impeller level rotationally is installed on the pump cover (10) of closed impeller working room, be provided with mechanical seal (9) between this axle and pump cover, described impeller working room has one and communicates with it and horizontally disposed entry end and one communicate and vertically disposed outlet end with it, bottom, described impeller working room is provided with the chamber that discharges water, and the described chamber that discharges water is provided with drain cock (2);
Be installed on the drive motor (12) of base, its pto is connected in the impeller (4) of the pump housing.
Further, the bore of the set outlet pipe of described outlet end is and enlarges shape gradually.
Further, described drive motor adopts threephase asynchronous machine.
Compared with prior art, the beneficial effects of the utility model are: (1) this pump has in the situation downforce maintenance that becomes current constant; (2) simple in structure, cost is low, high working efficiency.
Description of drawings
Fig. 1 is constant voltage tangent pump structural representation.
Fig. 2 is the phase diagram of constant voltage tangent pump broken section.
Embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.
As shown in Figure 1 and Figure 2, a kind of constant voltage tangent pump, it comprises: base 11; Be installed on the pump housing 1 of base, it has the impeller working room that is limited by housing, the spacing of impeller working room substantially horizontal is less than the distance of vertical direction, being convenient to impeller is in the vertical plane in this working room and rotates, be positioned at this impeller working room and be provided with impeller 4, the axle of described impeller level rotationally is installed on the pump cover 10 of closed impeller working room, pump cover stud 5, hexagon nut 6, spring washer 7 is installed on the pump housing, impeller is installed on impeller shaft by impeller nut 3, pump cover is located at and is matched with mounting hole that impeller shaft is installed and this mounting hole and has the part annular projection and increase the impeller shaft mounting stability with this, and be positioned at mounting hole and be provided with annular seal groove, between sealing groove and impeller shaft, seal ring is installed, be provided with mechanical seal 9 between this axle and pump cover, this mechanical seal is positioned at the inboard and adjacent with the seal ring position of pump cover, described impeller working room has one and communicates with it and horizontally disposed entry end and one communicate and vertically disposed outlet end with it, bottom, described impeller working room is provided with the impeller chamber that discharges water that is beyond one's reach, the chamber that discharges water is in outside the impeller turning radius with this and avoids disturbing, the described chamber that discharges water is provided with drain cock 2, and the bottom in the chamber that discharges water is located on the base and is supported the whole pump housing with this; Be installed on the drive motor 12 of base, described drive motor adopts threephase asynchronous machine, its pto is connected in the impeller 4 of the pump housing, the pto of drive motor and impeller shaft are in coaxial state, and all adopt horizontal mode to arrange, drive motor is whole to link to each other with the pump housing by hexagon head plug screw 8, hexagon nut 6, spring washer 7, and the link position of the pump housing and drive motor is on the pump cover, make the two be in an integral body, keep stability and the high efficiency of work.
The bore of the outlet pipe that described outlet end is set is and enlarges shape gradually, the outlet pipe end has adpting flange, the pipeline of entrance point also is the gradual change shape, outlet pipe is in bore away from impeller working room direction and increases gradually, and still being in bore away from impeller working room direction, the pipeline of entrance point increases gradually, yet the bore of outlet end is less than the bore with entrance point.
Can install with bearing for impeller shaft, this mounting type does not repeat them here as the common means of mechanical field.
The above only is preferred implementation of the present utility model, and protection domain of the present utility model is not limited in above-mentioned mode of execution, and every technological scheme that belongs to the utility model principle all belongs to protection domain of the present utility model.For a person skilled in the art, some improvement of under the prerequisite that does not break away from principle of the present utility model, carrying out, these improvement also should be considered as protection domain of the present utility model.
