SUCTION COVER HORIZONTAL SHAFT PUMP PUMP GATE AND PUMP GATE OPERATING METHOD
The present invention relates to an inlet cover, a horizontal shaft pump, a pump gate, and a method of operating the pump gate to reduce the amount of fluctuation in power consumption of a motor. The inlet cover includes a cover body (31) covering the front of a pump inlet with a lower portion open, wherein the cover body (31) has a rear wall (33) attachable to the pump inlet, a pair of side walls (35) and an upper wall (37); a cover inlet (39) that opens downwardly is formed between the lower edges of the side walls (35) one both sides as well as between the lower edge of the rear wall (33) and the leading edge of the upper wall (37); and a through portion (44) is formed on the rear wall (33) to penetrate the inside of the cover body (31), the outside of the cover body and the outside of a horizontal shaft pump. When the cover body (31) is attached to the pump inlet, the upper part of the through portion is positioned above the position of the cover inlet (39).
펌프 흡입구의 전방을 하부가 개구된 상태에서 덮는 커버 본체(31)를 갖고, 커버 본체(31)는 펌프 흡입구에 부착 가능한 후부벽(33)과 한 쌍의 측부벽(35)과 상부벽(37)을 갖고, 양방의 측부벽(35)의 하부 가장자리 사이이고 또한 후부벽(33)의 하부 가장자리와 상부벽(37)의 선단 가장자리 사이에, 하향으로 개구된 커버 흡입구(39)가 형성되고, 후부벽(33)에 커버 본체(31)의 내부와 커버 본체의 외부 및 횡축 펌프의 외부로 관통하는 관통부(44)가 형성되고, 커버 본체(31)를 펌프 흡입구에 부착한 상태에서, 관통부(44)의 상부가 커버 흡입구(39)의 위치보다 상방에 위치한다.
