水工闸门用于挡水和泄水,经常进行启闭操作。对于螺杆式启闭机.只要选择具有足够启闭吨位的启闭机,正常启闭不存在问题。然而,对于卷扬式启闭机,由于绳索只能传递拉力而不能传递压力,启闭机本身对闸门只产生启门力而不产生闭门力。这样就可能出现因闭门力不足,造成闸门无法关闭的问题。作者根据多年的实践,总结出了解决问题的办法。

Water gate for water and drainage, often open and close operation. For screw hoist.Only select hoist with enough open tonnage, the normal opening and closing there is no problem. However, for a winch hoist, since the rope can only transmit tension and can not transmit pressure, the hoist itself generates a gate force without generating a gate force. This may be due to lack of door closures, resulting in the problem of the gate can not be closed. According to many years of practice, the author summed up the solution to the problem.
