【発明の詳細な説明】 ［発明の技術分野］ 本発明は、ストレーナー外周からポンプ吸込口に至る
吸込路の構成に特徴を有する水中ポンプに関するもので
ある。Description: TECHNICAL FIELD [0001] The present invention relates to a submersible pump characterized by the configuration of a suction path from the outer periphery of a strainer to a pump suction port.

3 ‥‥ 3 are a number of ribs radially provided on the outer peripheral surface of the pump casing 1; 4 ‥‥ 4 are a number of vertical grooves which are recessed between the ribs 3 ‥‥ 3; Is a suction cover having a pump suction port 6 opened in the center, 7 is an annular strainer formed so that an inner peripheral surface thereof is in contact with the outer edge of the rib 3 リ ブ 3, 8 is its bottom plate, and 9 ‥‥ 9 is annular. A large number of long holes formed in the peripheral wall of the strainer 7, which are orthogonal to the outer edges of the ribs 3 # 3 when opened horizontally in the horizontal direction along the peripheral wall as shown in the drawings of the embodiment. When they are opened in an inclined manner, they intersect obliquely with the ribs 3 ‥‥ 3.

連通することになる。If the inner peripheral surface of the annular strainer 7 is fitted along the outer end surface of the ribs 3 # 3, each of the slots 9 # 9 has a plurality of ribs 3 # 3.
# 3 intersect with each other, whereby each long hole 9 # is connected to the vertical groove 4 # 4 in a manner divided into short holes, and the area where the strainer sucks the liquid is the upper edge of the pump casing 1. If a slight space S is provided between the lower surface of the suction cover 5 and the opposing surface of the bottom plate 8, the lower end of the vertical groove 4 ‥‥ 4 will allow The suction passage 10 that reaches the pump suction port 6 via the bottom surface communicates.
