Description

TECHNICAL FIELD

[0001] The present application relates to the field of water supply and drainage, in particular to a continuous water suction vacuum water guiding unit. BACKGROUND

[0002] The existing vacuum water guiding unit needs to fill water into the interior of the vacuum water guiding tank through the water filling opening on the vacuum water guiding tank until the liquid level reaches the height of the water suction pipe connection before use, and then the water pump is started to pump water. In the actual pumping process, the air in the water is released into the interior of the vacuum water guiding tank, so that the liquid level of the vacuum water pump continues to drop. When it drops to a certain height, it needs to be stopped and water is injected into the vacuum water guiding tank again, so that the pumping process is interrupted, which affects the pumping efficiency. CONTENT OF THE UTILITY MODEL

[0008] By adopting the technical scheme, the liquid level in the vacuum water guide tank is measured by the static pressure differential liquid level meter, when the liquid level in the vacuum water guide tank is less than one third, the control cabinet controls the electromagnetic valve to open, the water in the water storage tank enters the air suction tank through the second communication pipe and enters the third communication pipe, at this time, the air suction tank generates a flow rate, the pressure of the air suction tank is reduced, the gas in the vacuum water guide pump enters the air suction tank through the air suction pipe and is discharged through the third communication pipe, so that the air pressure of the vacuum water guide tank is reduced, at this time, in order to maintain the internal pressure of the vacuum water guide tank, the liquid level height rises.

[0009] Optionally, the upper portion of the third communication pipe is in the shape of a bell mouth, and the upper end of the third communication pipe and the lower end of the second communication pipe have a gap.

[0010] By adopting the technical scheme, the upper portion of the third communication pipe is in the shape of a bell mouth, so that the diameter of the end of the third communication pipe close to the second communication pipe is larger, and the water in the water storage tank is more easily discharged from the second communication pipe and enters the third communication pipe.

[0011] Optionally, the upper portion of the vacuum water guide tank is provided with an air outlet.

[0012] By adopting the technical scheme, the upper portion of the vacuum water guide tank is provided with an air outlet, so that when water is introduced into the vacuum water guide tank through the water guide opening, the air in the vacuum water guide tank can be discharged through the air outlet, so as to facilitate the water to enter the vacuum water guide tank smoothly.

[0016] By adopting the above technical solution, a first bending portion is provided, the outlet of the first bending portion is facing upward, and the third connecting pipe is provided with a second bending portion, the outlet of the second bending portion is facing obliquely upward, so that the bubbles coming out of the third connecting pipe are not easily returned to the vacuum water tank.

[0017] Optionally, a speaker cover is provided at one end of the second straight portion away from the second bending portion, and the opening of the speaker cover faces the side away from the second bending portion.

[0018] By adopting the above technical solution, a trumpet cover is further provided at the tail end of the second straight portion, and the trumpet cover faces the direction of the water pump, thereby further reducing the possibility of bubbles coming out of the second straight portion returning to the vacuum water tank.

[0019] Optionally, the air suction tank is located below the vacuum water induction tank.

[0020] In summary, this application includes at least one of the following beneficial technical effects:

[0021] 1. During the water diversion process, the internal water level of the vacuum water diversion tank will gradually drop. When the water level of the vacuum water diversion pump drops to a certain height, the static pressure differential level gauge detects the liquid level height and transmits an electrical signal to the control cabinet. The control cabinet controls the suction component to suck air, so that the upper air pressure of the vacuum water diversion pump is reduced. At this time, in order to balance the position air pressure and under the action of water diversion from the suction pipe, the liquid level in the vacuum water diversion tank will rise, so there is no need to stop the machine for water replenishment, which can improve the pumping efficiency;

[0022] 2.
