The invention relates to an automatic water diversion device which belongs to an auxiliary facility of a water pump. The automatic water diversion device comprises a water inlet pipe (1) of a centrifugal water pump, a water storage tank (2) and a water storage tank water diversion pipe (3), wherein the water inlet pipe (1) of the centrifugal water pump is communicated with the bottom side of the water storage tank (2); the water storage tank water diversion pipe (3) is communicated with the higher end of the water storage tank (2); the top of the water storage tank (2) is communicated with a water injection pipe (4); and the water injection pipe is provided with a control valve (5). The invention solves the problem that water injection is needed before the centrifugal water pump is started, and can fully inject the water storage tank when the centrifugal water pump is used for the first time, thereby enhancing the vacuum degree of a working system and increasing the water diversion height of the water diversion pipe.
Description
technical field [0001] The invention belongs to auxiliary facilities of water pumps, in particular to an automatic water diversion device. Background technique [0002] The water pump is filled with water in advance. When the pump is started, the impeller rotates to throw the water out of the pump casing, enters the outlet pipe and sends it to a high place, and generates a certain flow rate and lift. The water in the water pipe of the pump is replenished into the pump casing in time. , At this time, a vacuum will appear in the water diversion pipe, that is, a negative pressure state, that is, the pressure in the water diversion pipe is lower than atmospheric pressure. Therefore, the water in the pool, in the lake in the river, and in the canal flows into the center of the pump casing through the water pump pipe under the action of atmospheric pressure. At this time, the pressure in the pump casing is lower, and the water pump leads The water in the water pipe will continuou...
