Abstract
The utility model discloses a liquid pump which aims at providing a liquid pump with high work efficiency and long service life. The technic proposal is realized by that a shell is formed by a pump shell, the inlet seat, the outlet seat and the two ends of the inlet and the outlet of which are respectively connected with and moveably matched with the inlet seat and the outlet seat; the inlet seat and the outlet seat are respectively provided with sealing bearing seats; the two ends of the pump shaft which is provided with a spiral impeller are respectively arranged on the bearing seat; the edge of the spiral impeller is cast into a whole with the internal wall of the pump shell; the joint between the pump shell and the inlet seat and the outlet seat is provided with a mechanical sealing device.
Description
Technical field
The utility model relates to a kind of liquid pump.
Background technique
The traditional liquid pump mainly is made up of impeller and liquid pump housing, because rotating another, one of impeller and housing do not change, therefore, must leave certain interval between impeller and the liquid pump inner walls, two flow processs in the working procedure of pump, have objectively been formed, one is the normal workflow from impeller inlet to outlet, another then is that gap between impeller and liquid pump housing produces, reverse natural flow process from impeller outlet to import, this phenomenon has reduced the flow and the lift of pump to a certain extent, and the working efficiency of pump also decreases.Liquid pump is after use after a while, because wearing and tearing and corrosion, the gap between impeller and housing can constantly become big, and flow and lift progressively reduce, until using.Therefore, when selecting liquid pump, often all to select flow and lift, cause waste virtually than the actual high liquid pump of required index that uses.
Summary of the invention
In order to overcome the defective that above-mentioned prior art exists, the utility model provides a kind of high working efficiency, the liquid pump of long service life.
The utility model is achieved in that it comprises housing and the pump shaft that impeller is housed, and described housing is joined with inlet port and outlet port respectively by inlet port, outlet port and its two ends and the movable pump case that cooperates is formed; Be respectively equipped with sealed bearing on inlet port and the outlet port, the two ends that the pump shaft of helical runner is housed are contained on the bearing support respectively; The edge of helical runner and pump case inwall are cast as one; Pump case and inlet port and outlet port connecting part are provided with mechanical seal device.
The structure that the utility model adopts the edge of pump case inwall and helical runner to be cast as one makes between helical runner and the pump case inwall very close to each otherly, has stopped reverse natural flow process, and working efficiency is improved, simultaneously the prolongation in working life.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is a structural representation of the present utility model.
Embodiment
Shown in Figure 1, it comprises housing and the pump shaft 5 that impeller is housed the utility model.Described housing is joined with inlet port 6 and outlet port 4 respectively by inlet port 6, outlet port 4 and its two ends and the movable pump case 3 that cooperates is formed.Be respectively equipped with sealed bearing on inlet port 6 and the outlet port 4, the two ends that the pump shaft 5 of helical runner 2 is housed are contained on the sealed bearing respectively.The edge of helical runner 2 and pump case 3 inwalls are cast as one.Pump case 3 is provided with mechanical seal 1 device with inlet port 6 and outlet port 4 connecting parts, and the sealing device is a prior art, and known to industry those of ordinary skill, its concrete structure and installation process no longer describe in detail.During work, 5 rotations of driven by motor pump shaft, with helical runner 2 and pump case 3 companion rotations that pump shaft 5 is connected as a single entity, liquid enters from inlet port 6, pumps from outlet port 4.Because there is not the gap between helical runner 2 and pump case 3 inwalls, so, there is not reverse natural flow process, working efficiency is further enhanced, and prolong working life.Because pump shaft 5 two ends are contained in respectively on the stuffing box bearing of inlet port 6 and outlet port 4, pump case 3 is except that with mechanical seal device 1 contacts, do not contact with other any parts, therefore wearout parts only limits to mechanical seal device 1 and stuffing box bearing, the part replacement cost is low, and greatly improve the working life of complete machine critical piece.
