一般に、上記のような水中ポンプ用モータは絶縁性が低下するとステータコイ ル２の電気回路以外に電気的な回り込み回路が生じて電流の一部が水中に流れ、 水中のイオン増加により電気伝導度が上昇するために水中ポンプにおける接水部 の腐食促進、モータの性能低下、水中ポンプとの接触に伴う感電等の不具合が発 生する。 Generally, when the insulation of a submersible pump motor as described above deteriorates, an electric sneak circuit occurs in addition to the electric circuit of the stator coil 2 and a part of the current flows into the water, and the electrical conductivity increases due to the increase of ions in the water. As the temperature rises, problems such as accelerated corrosion of the water contact part of the submersible pump, deterioration of motor performance, and electric shock due to contact with the submersible pump will occur.

図１および図２は本考案の一実施例に係る水中ポンプ用モータの説明図である 。図において、本実施例に係る水中ポンプ用モータは送水などに使用されるもの で、水中ポンプと一体に組込まれて内部に通水される自己冷却式になっており、 ステータコイル２は予め表面を例えばエポキシ樹脂やエナメル等の絶縁材で覆っ て絶縁処理を施された上で、ケーシング６内に挿入されて固定されるようになっ ている。一般に、例えば水道水などの水は電気的に伝導性を有しており、本モー タのように内部に通水される自己冷却式のモータは接水部に取付けられるステー タコイル２などの通電部品に対して絶縁材をコーティングすることにより絶縁処 理を施している。この絶縁処理における絶縁性は絶縁層が厚いほど良好な特性と なるが、部分的に絶縁層の薄い欠陥があっても絶縁不良を引き起こすため、本モ ータはケーシング６を絶縁層の欠陥が生じる可能性のある組立て作業が完了した 後に再度ステータコイル２に絶縁処理を施すことができるように分割構造として おき、ステータコイル２の組立後にも再度ステータコイル２の表面にケーシング ６の前後から絶縁処理を施すことにより絶縁性に対する信頼の向上を計ることが できる。なお、符号１はインペラ、３はマグネットロータ、４は制御部、５はボ ルト、７は後蓋、８は前蓋、９は回転軸、１０はベアリングである。 1 and 2 are explanatory views of a motor for a submersible pump according to an embodiment of the present invention. In the figure, the submersible pump motor according to the present embodiment is used for water supply, etc., and is a self-cooling type that is integrated with the submersible pump and allows water to pass inside. After being covered with an insulating material such as epoxy resin or enamel for insulation treatment, the casing 6 is inserted and fixed in the casing 6. Generally, water such as tap water is electrically conductive, and a self-cooling motor such as this motor that allows water to flow inside is energized by the status coil 2 attached to the water contact part. The parts are insulated by coating them with an insulating material. The insulating property in this insulation treatment becomes better as the insulating layer is thicker. However, even if there is a partial defect in the insulating layer, defective insulation occurs. The stator coil 2 has a divided structure so that it can be insulated again after the assembly work that may occur is completed. Even after the stator coil 2 is assembled, the surface of the stator coil 2 is again insulated from the front and back of the casing 6. By applying the treatment, the reliability of insulation can be improved. Reference numeral 1 is an impeller, 3 is a magnet rotor, 4 is a control unit, 5 is a bolt, 7 is a rear lid, 8 is a front lid, 9 is a rotary shaft, and 10 is a bearing.
【０００７】 即ち、図１に示すように本モータはステータコイル２をケーシング６内に挿入 して固定した状態でステータコイル２全体の再絶縁処理を施すことができるよう に、ケーシング６の前部もケーシング６と前蓋８とに分割されており、前蓋８は ボルト５でケーシング６に固定される構造になっていてボルト５により着脱が可 能である。従って、ステータコイル２の組立て段階ではケーシング６の前蓋８及 び後蓋７を取外した状態で組立てた後、再度ステータコイル２の表面全体にケー シング６の前後から絶縁処理を施すことができるようになっている。That is, as shown in FIG. 1, in the present motor, the stator coil 2 is inserted into the casing 6 and fixed to the front portion of the casing 6 so that the stator coil 2 can be reinsulated. Is also divided into a casing 6 and a front lid 8. The front lid 8 is fixed to the casing 6 with bolts 5, and can be attached and detached with the bolts 5. Therefore, at the assembly stage of the stator coil 2, after the casing 6 is assembled with the front cover 8 and the rear cover 7 removed, the entire surface of the stator coil 2 can be subjected to insulation treatment before and after the casing 6. It is like this.
【０００８】 ステータコイル２を組立てる場合は、図２に示すように先ずステータコイル２ 単体を組立てた状態で低粘度エポキシ樹脂等の絶縁用ワニス１２により表面を覆 い、次にポリパラキシレン（ＭＩＬ−１−４６０５８規格品) 等のコーティング を施し、その上でステータコイル２をケーシング６内に組込む。そして、ステー タコイル２の表面及びケーシング６との合わせ面などに再度上述と同様に絶縁処 理を施すことにより、ステータコイル２組込み作業時における絶縁層の傷などに よる絶縁低下を防ぐとともに、ステータコイル２全体の絶縁性を向上させること ができ、絶縁性に対する信頼の高い水中ポンプ用モータにすることができる。When assembling the stator coil 2, as shown in FIG. 2, first, the surface of the stator coil 2 is assembled with an insulating varnish 12 such as a low-viscosity epoxy resin in the assembled state, and then the polyparaxylene (MIL) is used. -1-46058 standard product) and the like, and the stator coil 2 is assembled in the casing 6 on it. Then, the surface of the stator coil 2 and the mating surface with the casing 6 are again subjected to the insulation treatment in the same manner as described above to prevent the insulation from being deteriorated due to the damage of the insulation layer during the assembling work of the stator coil 2 and the stator. The insulation of the coil 2 as a whole can be improved, and the motor for a submersible pump with high reliability can be obtained.
【０００９】[0009]
本考案に係る水中ポンプ用モータは前記のように構成されており、ケーシング 内にステータコイルを組込んだ後でも再度ステータコイルに絶縁処理を施すこと ができるので絶縁性に関して高い信頼が得られ、水中ポンプにおける接水部の腐 食促進、モータの性能低下、水中ポンプとの接触に伴う感電等が未然に防止され る。 The motor for a submersible pump according to the present invention is configured as described above, and since the stator coil can be subjected to the insulation treatment again even after the stator coil is assembled in the casing, high reliability can be obtained with respect to the insulation property. Acceleration of corrosion of the water contact part of the submersible pump, deterioration of motor performance, and electric shock due to contact with the submersible pump are prevented in advance.
