Abstract
The utility model relates to a positive negative pressure conversion equipment, the device include the barrel, are provided with the delivery port in the upper end of barrel, are provided with the water inlet that is used for with negative pressure jar intercommunication at the middle part of barrel, are provided with the immersible pump in the barrel, and the immersible pump enters into the device that the water in the barrel was caught through the delivery port for following the water inlet. It makes negative pressure jar and the suction pump can to arrange in the coplanar that construction convenience has saved the engineering time greatly, has improved the efficiency of construction, and has saved the cost of construction greatly, also can not receive the restriction in place, and its cubical space occupancy is extremely low, and its application range is wider, more nimble.
Description
Technical field
The utility model relates to a kind of water pump, i.e. the water pump of positive/negative-pressure conversion.
Background technique
When extracting the water in negative-pressure cup, traditional water pump has air inlet or gas leak phenomenon, and using effect is not good.General all by negative-pressure cup high position layout, suction pump low position, potential difference is generally greater than 10m, utilizes the static pressure of water to eliminate negative pressure, makes the entry end of pump be malleation.Make construction get up so very inconvenient, take solid space comparatively large, very easily by the impact in place.
Summary of the invention
Goal of the invention:
The invention provides a kind of positive/negative-pressure conversion equipment, its object solves the problem existing for equipment in the past.
Technological scheme:
A kind of positive/negative-pressure conversion equipment, it is characterized in that: this device comprises cylindrical shell, the upper end of cylindrical shell is provided with water outlet, the middle part of cylindrical shell is provided with the water intake for being communicated with negative-pressure cup, in cylindrical shell, be provided with submersible pump, submersible pump is the device water entered into from water intake in cylindrical shell can got by water outlet.
The position of submersible pump is lower than water intake.
Cylindrical shell top is provided with electrical wire interface, and its interior waterproof seals, and the electric wire of submersible pump is connected through the outer general power of this interface and equipment.
Be connected with negative-pressure cup when cylindrical shell top is provided with use, make the pressure interface that the pressure in cylindrical shell is identical with negative-pressure cup.
There is upper cover sealing flange on cylindrical shell top, ensure the sealing completely of upper cover.
Advantage and effect
The present invention is a kind of positive/negative-pressure conversion equipment, it makes negative-pressure cup and suction pump can arrange in same plane, easy construction, greatly save the engineering time, improve efficiency of construction, and greatly save the cost of construction, also can not be subject to the restriction in place, its solid space occupancy rate is extremely low, its using scope more extensively, more flexible.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure 1, cylindrical shell; 2, submersible pump; 3, water intake; 4, water outlet; 5, electrical wire interface; 6, upper cover sealing flange; 7, pressure interface; 8, water outlet direction; 9, pressure communication pipe; 10, negative-pressure cup; 11, intake direction.
Embodiment
Below in conjunction with accompanying drawing, the present invention is described further:
As shown in the figure, the present invention proposes a kind of positive/negative-pressure conversion equipment, this device comprises cylindrical shell 1, the upper end of cylindrical shell 1 is provided with water outlet 4, the water intake 3 for being communicated with negative-pressure cup is provided with at the middle part of cylindrical shell 1, in cylindrical shell 1, be provided with submersible pump 2, submersible pump 2 is the device water entered into from water intake in cylindrical shell can got by water outlet.
Cylindrical shell top is provided with electrical wire interface 5, and its interior waterproof seals, and the electric wire of submersible pump is connected through the outer general power of this interface and equipment.
Be connected with negative-pressure cup when cylindrical shell top is provided with use, make the pressure interface 7 that the pressure in cylindrical shell is identical with negative-pressure cup.
There is upper cover sealing flange 6 on cylindrical shell top, ensure the sealing completely of upper cover, ne-leakage.
When model utility uses, the water intake 3 of cylindrical shell is communicated with negative-pressure cup 10, and the pressure communication pipe 9 be communicated with pressure interface 7 communicates with negative-pressure cup 10, and pressure interface 7 makes the pressure in cylindrical shell identical with negative-pressure cup, the each interface of equipment or flange seal all completely, ensure ne-leakage.Water in negative-pressure cup enters in cylindrical shell by water intake, and negative pressure water is got by water outlet by submersible pump.
The utility model well solves in the past existing problem, is more suitable for applying on a large scale.
