Abstract
The utility model provides a semi-closed energy-saving submersible pump. The semi-closed energy-saving submersible pump comprises a pump shell (3), a rotor (4), a stator coil (5), an impeller (9), a water inlet (10) and a water outlet (11), wherein a closed chamber (6) is formed between an impeller cavity (8) and a pump body cavity; and two mechanical seals (7) are arranged on a rotating shaft in the closed chamber (6). The semi-closed energy-saving submersible pump is characterized in that the pump body cavity is divided into upper and lower sections; the middle part of the pump body cavity is fixed and sealed; binding posts (2) are arranged on the pump shell (3), are obtained by sintering ceramic, and are sealed with the pump shell (3) in an insulating mode; and the outer side of the pump shell (3) where the binding posts (2) are positioned is provided with a sealed junction box (1). The major structure of the conventional submersible pump is not changed, only the pump body cavity is divided into two sections and is sealed, and one mechanical seal is added between the impeller and the closed cavity, so the submersible pump has a simple structure, is a semi-closed hollow body, and has a good sealing effect, and the service life of the submersible pump is effectively prolonged.
Description
Technical field
The utility model belongs to a kind of water pump, mainly proposes a kind of semi-enclosed energy-saving submersible pump of good sealing effect.
Background technique
Existing submersible pump is general main to be made up of pump case, stator coil, rotor bearing, water wheels etc., joint sealing everywhere, and the rotor axis mechanical sealing, water wheels are fixed on the rotating shaft lower end.Because its pump case segmentation is many, the shaft sealing weak effect, lead directly gets into the pump housing in addition, and the time one is long, and the water capacity is prone to penetrate in the pump case chamber from sealing part, causes the motor electric leakage, burns out, and influences its working life.
Summary of the invention
The purpose of the utility model promptly is to propose a kind of good sealing effect, the semi-enclosed energy-saving submersible pump of long service life.It mainly comprises between pump case, rotor, stator iron core coil, impeller, the empty chamber of leaf willow and the pump block sky has a closed chamber; Have two mechanical shaft seal in it, pump housing chamber is divided into upper and lower two sections, the middle part fixing seal; In point of incoming cables, housing top wiring terminal is set; Wiring terminal adopts the porcelain sintering, with the pump case insulated enclosure, and in the hull outside at wiring terminal housing place one sealed terminal box is set.One mechanical seal is set in the rotating shaft between impeller and the closed chamber.
The purpose of the utility model is realized by following technological scheme, has developed a kind of semi-enclosed energy-saving submersible pump, and this semi-enclosed energy-saving submersible pump comprises pump case 3, rotor 4, stator coil 5, impeller 9, water intake 10 and water outlet 11; Between impeller cavity 8 and the pump housing chamber closed chamber 6 is set; In the rotating shaft in it two mechanical seals 7 are set, it is characterized in that described pump housing chamber is divided into upper and lower two sections; The fixing seal at the middle part; Cut open the anchoring wire place on the pump case 3 wiring terminal 2 be set, wiring terminal 2 adopt the porcelain sintering and with pump case 3 insulated enclosures, at wiring terminal 2 place pump case 3 arranged outside one sealed terminal box 1.
A mechanical seal 7 is set in the rotating shaft between described impeller 9 and the closed chamber 6.
Described wiring terminal 2 adopts gluing back and pump case 3 insulated enclosures of connecing of epoxy type.
The utility model does not change the agent structure of existing submersible pump, just is divided into two sections sealings at the pump case body cavity, and between impeller and closed chamber, has increased by a mechanical seal; So it is simple in structure; Whole form semi-enclosed month empty body, good sealing effect has prolonged working life of submersible pump effectively.
Description of drawings
Accompanying drawing 1 is the utility model overall structure schematic representation.
Among the figure, 1, sealed terminal box, 2, wiring terminal, 3, pump case, 4, rotor, 5, stator coil, 6, closed chamber, 7, play the tool sealing, 8, impeller cavity, 9, impeller, 10, water intake, 11, water outlet.
Embodiment
The accompanying drawing that provides in conjunction with embodiment further specifies its structure:
Shown in accompanying drawing 1; This semi-enclosed energy-saving submersible pump comprises pump case 3, rotor 4, stator coil 5, impeller 9, water intake 10 and water outlet 11; Between impeller cavity 8 and the pump housing chamber closed chamber 6 is set, in the rotating shaft in it two mechanical seals 7 is set, it is characterized in that: described pump housing chamber is divided into upper and lower two sections; The fixing seal at the middle part; Cut open the anchoring wire place on the pump case 3 wiring terminal 2 be set, wiring terminal 2 adopt the porcelain sintering and with pump case 3 insulated enclosures, at wiring terminal 2 place pump case 3 arranged outside one sealed terminal box 1.
A mechanical seal 7 is set in the rotating shaft between described impeller 9 and the closed chamber 6.
Described wiring terminal 2 adopts gluing back and pump case 3 insulated enclosures of connecing of epoxy type.
In addition, the utility model and not meaning that by schematic representation and specification limits to, and under the prerequisite that does not break away from design aim and principle thereof, can change to some extent.
