Abstract
The utility model discloses a protective device of a submersible pump. The protective device of the submersible pump comprises an upper slim pipe, a thick pipe and a three-section type stepped reducer of a lower slim pipe from top to bottom, wherein the thick pipe comprises an upper thick pipe and a lower thick pipe which are in detachable connection, the upper thick pipe and the upper slim pipe are in integral connection, the lower thick pipe and the lower slim pipe are in integral connection, a turning plate which can turn up and down is arranged on the connection joint of the lower thick pipe and the lower slim pipe, the turning plate is capable of covering the integral upper opening of the lower slim pipe, the lower surface of the turning plate is provided with a seal ring which is coaxial with the lower slim pipe, and the external diameter is larger than the internal diameter of the lower slim pipe. The protective device of the submersible pump is installed between a water outlet of the submersible pump and a pump pipe, water in the pump pipe is not regurgitant, so that friction and wear caused by an inverse pump body between a stator and a rotor of the pump body and the bearing seats of a water wheel thrust plate are avoided, the working life of the pump body is prolonged, rapid water outlet when the submersible pump is restarted is achieved, and the energy saving purpose is achieved.
Description
Technical field
The utility model relates to a kind of counterpart of submersible pump, relates in particular to a kind of submersible pump protective gear.
Background technique
At present a lot of rural areas of China also do not have tap water, usefulness be that submersible pump is taken out underground water and used.Existing submersible pump in use, self-supporting electricity flows out to water needs 2-3 minute, cause the waste of electric energy, the water that resides in after the outage in the pump line probably has 50-60 rice high, reflux downwards automatically from a high position in the capital, backflow can cause friction unnecessary between the stator of submersible pump and rotor and the unnecessary wearing and tearing of water wheels thrust collar bearing seat, has reduced the Acceptable life of submersible pump.
Summary of the invention
For the problem that above-mentioned prior art exists, the utility model purpose is to provide a kind of submersible pump protective gear, can effectively protect submersible pump, prolongs its working life.
The technical solution of the utility model is: a kind of submersible pump protective gear; comprise the 3 stops ladder reducer pipe that is respectively tubule, extra heavy pipe and lower tubule from top to bottom; described extra heavy pipe is removably connected by upper extra heavy pipe and lower extra heavy pipe and forms; described upper extra heavy pipe is connected with upper tubule one; described lower extra heavy pipe is connected with lower tubule one; the joint of lower extra heavy pipe and lower tubule is provided with the turnover panel that can stir up and down; described turnover panel covers the whole suitable for reading of lower tubule; the lower surface of described turnover panel is provided with the seal ring coaxial with lower tubule, and the external diameter of seal ring is greater than the internal diameter of lower tubule.
As preferably, the place suitable for reading of described upper tubule is provided with the flange that is connected with pump line, and the end opening place of described lower tubule is provided with the flange that is connected with the water outlet of submersible pump.
As preferably, the upper end of the lower end of described upper extra heavy pipe and lower extra heavy pipe is respectively equipped with interconnective flange.
As preferably, described upper tubule and lower tubule are consistent with the diameter of pump line.
The beneficial effects of the utility model are: be installed between the water outlet and pump line of submersible pump, after the submersible pump outage, water in the pump line does not reflux, the friction, the wearing and tearing that avoid between pump housing stator and rotor, water wheels thrust collar bearing seat cause because of pump housing reversing, thereby prolong the working life of the pump housing, also can rapid water outlet when again starting submersible pump, reach energy-conservation purpose.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Among the figure: 1, upper tubule; 2, lower tubule; 3, upper extra heavy pipe; 4, lower extra heavy pipe; 5, turnover panel; 6, seal ring.
Embodiment
As a kind of mode of execution of the present utility model; as shown in Figure 1; a kind of submersible pump protective gear; comprise the 3 stops ladder reducer pipe that is respectively tubule 1, extra heavy pipe and lower tubule 2 from top to bottom; described extra heavy pipe is combined by upper extra heavy pipe 3 and lower extra heavy pipe 4; the upper end of the lower end of described upper extra heavy pipe 3 and lower extra heavy pipe 4 is respectively equipped with interconnective flange, and upper extra heavy pipe 3 and lower extra heavy pipe 4 removably connect by flange.Described upper extra heavy pipe 3 is connected with upper tubule 1 one, described lower extra heavy pipe 4 is connected with lower tubule 2 one, lower extra heavy pipe 4 is provided with the turnover panel 5 that can stir up and down with the joint of lower tubule 2, described turnover panel 5 covers the whole suitable for reading of lower tubule 2, the lower surface of described turnover panel 5 is provided with the seal ring 6 coaxial with lower tubule 2, and the external diameter of seal ring 6 is greater than the internal diameter of lower tubule 2.Described upper tubule 1 and lower tubule 2 are consistent with the diameter of pump line, and the place suitable for reading of described upper tubule 1 is provided with the flange that is connected with pump line, and the end opening place of described lower tubule 2 is provided with the flange that is connected with the water outlet of submersible pump.
The utility model is installed between the water outlet and pump line of submersible pump, when submersible pump is worked, current are washed turnover panel 5 open and are outputed to ground through pump line, after the submersible pump outage, the water of pump line the inside is because of earth attraction, the meeting adverse current, and through upper tubule 1, extra heavy pipe is got back to turnover panel 5 places, turnover panel 5 is already by the refunds original position simultaneously, seal ring 6 is with the sealing suitable for reading of lower tubule 2, water no longer is back in the submersible pump, thereby avoids between pump housing stator and rotor, the friction that water wheels thrust collar bearing seat causes because of pump housing reversing, wearing and tearing, thereby the working life of the prolongation pump housing, also can rapid water outlet when again starting submersible pump, reach energy-conservation purpose.Upper extra heavy pipe 3 and lower extra heavy pipe 4 can split and come, and conveniently keep in repair when turnover panel 5 damages.
