【発明の詳細な説明】 〔産業上の利用分野〕 本発明は、液化天然ガス等を圧送する立軸サブマージ
ブルポンプに係り、特にその分解・組立方法に関するも
のである。TECHNICAL FIELD The present invention relates to a vertical submerged pump for pumping liquefied natural gas or the like, and more particularly to a disassembly / assembly method thereof.
従来、立軸サブマージブルポンプについては、特開昭

58-183892. When disassembling the pump, lift the head cover that is integral with the hydrodynamic part and the motor part, pull it out from the suction port and carry it to the maintenance building where it is separated from the hydrodynamic part and the motor part. It had a structure to disassemble and inspect the force section and the motor section. The saxion pot is left at the installation site as it is.
上記従来技術は、重くて形状の複雑なヘツドカバーを
メインテナンス建屋に運ぶことから、以下のような問題
があつた。The above-mentioned conventional technique has the following problems because it carries a heavy and complicated head cover to the maintenance building.
メインテナンス建屋に運びこむ重量が重くなり、特に
大形ポンプではその重量が建屋クレーンの容量をこえて
しまうため、屋外で作業をしなければならない。Since the weight to be carried into the maintenance building becomes heavy, especially for large pumps, the weight exceeds the capacity of the building crane, so it is necessary to work outdoors.
吐出ノズルやケーブルノズルの突起物のついたヘツド
カバーをつけたまま、ポンプ本体の横倒し、反転・運搬
作業をしなければならず、作業性が非常にわるい。The workability is extremely poor because the pump body must be laid down, inverted, and transported while the head cover with protrusions of the discharge nozzle and cable nozzle is attached.
サクシヨンポツト養生のため、ポンプ閉止板を用意し
なければならないが、この閉止板は圧力容器ふたとなる
ため厚く重くなり、かつ高価である。A pump closing plate must be prepared for curing the pot, but this closing plate becomes a pressure vessel lid, which makes it thick and heavy and expensive.
同時に複数台のポンプをメインテナンスすることがあ
るため、閉止板は設備にあるポンプ台数分準備しておく
必要があつた。このため広い保管スペースが必要であつ
た。Since multiple pumps may be maintained at the same time, it is necessary to prepare the closing plates for the number of pumps in the equipment. Therefore, a large storage space is required.
本発明の目的は、メインテナンス建屋に運びこむ部品
数と重量をへらしてメインテナンス性を向上させると共
に、閉止板を不要とすることにある。An object of the present invention is to improve the maintainability by reducing the number and weight of the components carried into the maintenance building, and to eliminate the need for a closing plate.
上記目的を達成するため本発明は、サクシヨンポツト

部部品のみを、メインテナンス建屋に運び込むようにし
たものである。In order to achieve the above object, the present invention is such that a head cover and a pump main body including a fluid force portion and a motor portion are separated from each other on a suction pot. That is,
The pressure pot and the head cover that make up the pressure vessel and do not have bearings or various sliding parts and do not require replacement of parts are left at the pump installation place, and only necessary parts for maintenance are carried into the maintenance building. It was done.
そのために、ポンプメインテナンス装置として、ヘツ

時、ヘツドカバーはサクシヨンポツトの閉止板として使
用できる。Since the present invention is provided with the head cover separating frame, the head cover and the pump main body can be separated on the suction pot. Therefore, at the time of maintenance, only the necessary parts can be carried into the maintenance building. At that time, the head cover can be used as a closing plate for the suction pot.

ツト３には、再度ヘツドカバー４を被せて養生する。As shown in FIG. 2, after the head cover 4 and the stage case 1 containing the hydrodynamic part and the motor case 2 containing the motor part are lifted, as shown in FIG. 3, the upper flange 3a of the suction pot 3 is shown. The head cover separation frame A is inserted and placed on the upper side to support the upper flange 2a of the motor case 2. In this state, the bolt 5 connecting the head cover 4 and the motor case 2 is loosened and pulled out in the lateral direction. Next, as shown in FIG. 4, only the head cover 4 is lifted and temporarily placed on the side of the suction pot, and then, as shown in FIG.
Lift the pump body consisting of the power cable 2b, etc., pull it out, place it horizontally on a truck prepared nearby, and carry it to the maintenance building. The succession pot 3 is again covered with a head cover 4 for curing.

狭くて良いなどの効果がある。As described above, according to the present invention, the cable nozzle 4b
Also, the shape of the discharge nozzle 4a and other projections is complicated, and the weight is heavy, accounting for about 50% of the pump body. There is no need to bring the head cover 4 to the maintenance building. Further, since the head cover 4 can be used as it is as a closing plate, it is not necessary to separately carry an expensive closing plate which requires a large storage space. Even if there are a large number of pumps in the equipment, only one head cover support base A or several head cover support bases A may be provided according to the size of the suction pot, so that the storage space may be small.

That is, the crane in the maintenance building has a small capacity, there is no need to prepare a closing plate, and the number of maintenance work steps is reduced. Also, there is no need to worry about damaging the nozzle of the head cover when the pump is laid down sideways, which is a safety effect.
