Abstract
The utility model relates to an improved vertical self-sucking pump anti-siphonage device, mainly comprising a pump body, a pump cavity and a vane wheel which are arranged inside the pump body, and a water inlet pipe and a water outlet pipe which are fixedly connected with the pump cavity. An elbow which runs through the water inlet pipe and the water outlet pipe is fixedly arranged between the water inlet pipe and the pump cavity. The port position where the elbow is positioned inside the water inlet pipe is lower than the port position where the elbow is positioned inside the pump cavity. With the anti-siphonage device with above structure, the vertical self-sucking pump no longer reduce the working efficiency to overcome the solution sucking resistance which is produced by the check valve or electronic valve adopted by the prior art, thereby saving the energy consumption of the vertical self-sucking pump, and the utility model has the advantages of simple structure, safe and reliable performance and greatly reducing the maintaining cost. The port position where the elbow is positioned inside the pump cavity is higher then the end surface of the vane wheel, which achieves the watering one time, self-sucking for life demand of the vertical self-sucking pump.
Description
Technical field
The utility model relates to a kind of anti-siphon means, especially refers to a kind of anti-siphon means that is used on the vertical self-sucking pump.
Background technique
At present, vertical self-sucking pump is installed again plurality of advantages such as convenient owing to both had self-absorption function, is widely used in many occasions.Vertical self-sucking pump commonly used adopts the working principle of vacuum self-priming; the pump housing is designed to seal pot type; the pump chamber part is installed in the pump housing with middle wheel; just can directly get liquid after filling liquid; features simple structure; reliable operation, but there is a fatal weakness in it is exactly because during water pump operation; be in bigger negative pressure state in the inlet pipeline; after the shutdown, the water in the pump chamber can be back to liquid storage tank from inlet pipeline because of negative-pressure siphon, till the negative pressure in inlet pipeline disappears; though the water in the pump housing can all not missed at this moment; but the water level in the pump housing can descend and be lower than impeller, just can not get liquid when starting shooting again, must add some liquid again in the pump housing; impeller is immersed in the liquid; just can get liquid during start, therefore the vertical self-sucking pump of this structure can not stop oversize, though it is simple in structure; the energy self-priming; and do not need self-priming time, but it can not realize that self-priming is necessary " once add water, the performance requirement of lifelong self-priming.In order to prevent above-mentioned siphonage, need to set up the device that destroys siphonage on the pump.Thereby make to shut down still to have in the pump chamber of back and start needed drainage liquid next time.And prior art mainly contains two kinds, and is a kind of, at pump water inlet pipe place safety check is installed, and the shortcoming of this structure is: safety check poor reliability on the one hand, and damage easily and still occur siphonage easily; Increase the imbibition resistance on the other hand, influenced the efficient of pump.Another kind is as shown in Figure 2: at inlet pipeline electronics valve 5 is installed, the shortcoming of this structure is: electronic valve 5 valve blocks are not closed completely easily, especially when high-risk occasion is used, because electromagnetic action, initiation fire or blast easily.
Summary of the invention
The utility model provides a kind of improved vertical self-sucking pump anti-siphon means, its purpose is the deficiency at above existence, and a kind of reliability height is provided, and is difficult for corrupted, lower maintenance cost greatly, energy efficient and vertical self-sucking pump anti-siphon means simple in structure.
For achieving the above object, technical solutions of the utility model are:
Improved vertical self-sucking pump anti-siphon means, mainly comprise: the pump housing, pump chamber and impeller are installed in the pump housing, intake pipe and the outlet pipe pump chamber that is fixedly connected, it is characterized in that: fixedly install the bend pipe of a perforation intake pipe and pump chamber between described intake pipe and the pump chamber, the port position that described bend pipe is arranged in intake pipe is lower than the port position that it is positioned at pump chamber.
A port of described bend pipe is positioned at pump chamber, and the position of this port of bend pipe is higher than the position of impeller end face.
The part of bend pipe is within the pump chamber, and its shape is " U " type.
The part of bend pipe is within the intake pipe, and its end is bent downwardly.
The usefulness of technique scheme is:
The bend pipe of one perforation intake pipe and pump chamber is set between intake pipe and the pump chamber, and the port position that bend pipe is arranged in intake pipe is lower than the port position that it is positioned at pump chamber.The anti-siphon means that structure like this is provided with is simple in structure and performance is safe and reliable, because of bend pipe is difficult for corrupted, maintenance cost reduces greatly, and the imbibition resistance that vertical self-sucking pump can not produce because of the safety check of available technology adopting reduces its working efficiency, has saved vertical self-priming pump work energy consumption.
Description of drawings
Fig. 1 is the utility model vertical self-sucking pump structural representation;
Fig. 2 is a prior art vertical self-sucking pump structural representation.
Embodiment
The utility model now is described in conjunction with the accompanying drawings and embodiments.
As shown in Figure 1: improved vertical self-sucking pump anti-siphon means, mainly comprise: the pump housing 1, pump chamber 11 is installed in the pump housing 1 with impeller 12, intake pipe 2 and outlet pipe 4 pump chamber 11 that is fixedly connected, fixedly install the bend pipe 3 of a perforation intake pipe 2 and pump chamber 11 between described intake pipe 2 and the pump chamber 11, port 31 positions that described bend pipe 3 is arranged in intake pipe 2 are lower than its port that is positioned at pump chamber 11 32 positions.The shape that is positioned at pump chamber 11 of bend pipe 3 is " U " type, and the end that is arranged in intake pipe 2 is bent downwardly.The anti-siphon means that structure like this is provided with is simple in structure and performance is safe and reliable, because of bend pipe is difficult for corrupted, maintenance cost reduces greatly, vertical self-sucking pump needn't reduce its working efficiency because of the imbibition resistance of safety check that overcomes available technology adopting or generation, saved vertical self-priming pump work energy consumption, in addition, a port 32 of described bend pipe 3 is positioned at pump chamber 11, the position of this port 32 of bend pipe 3 is higher than the position of impeller 12 end faces, can realize the vertical self-sucking pump performance requirement of necessary " once adding water, lifelong self-priming ".
