Description
Technical field
The utility model relates to the submersible pump technical field, relates in particular to the entrance guiding submersible pump.
Background technique
Present disclosed permanent magnet synchronous motor submersible pump does not all adopt the entrance guiding structure.For example, the disclosed a kind of submersible pump of Chinese patent literature CN 202381343U, its structure as shown in Figure 1, comprise water pump stator 101, water cavity 1011, water outlet 1012, rotor shaft 106, rotor chamber 1013, rotor 102, impeller 103, water cavity lid 104 and water inlet cover 105, wherein, water cavity lid 104 is provided with the center and goes into discharge orifice 1041, water cavity 1011 is positioned at an end of water pump stator 101,104 pairs of water cavities 1011 of water cavity lid seal press fit, rotor 102 cooperates installation with water pump stator 101 by rotor chamber 1013, rotor 102 1 ends are equipped with the impeller 103 that cooperates with water cavity 1011 to water outlet 1012 pump water, water outlet 1012 is communicated with water cavity 1011, water inlet is covered 105 and is used to seal water cavity lid 104, and its end face was provided with the grid mouth 1051 of water.
The working principle of above-mentioned submersible pump is: submersible pump is immersed in the water, under the condition of energising, permanent-magnet synchronous motor rotor 102 impeller 103 rotate, current covers 105 grid mouth 1051 from water inlet and enter submersible pump and cover 104 center through water cavity to go into discharge orifice 1041 and flow to water cavity 1011, by 103 pairs of current actings of impeller, current are flowed out from water outlet 1012, and so circulation realizes the drain function of submersible pump.Though this submersible pump is simple in structure, be easy to use, but it is consistent with impeller height that the discharge orifice height is gone at the center of water cavity lid, highly higher, when the environment water level drops to when being not enough to flood whole center and going into discharge orifice, the center is gone into the discharge orifice place and will be existed air stream and two kinds of fluids mixing of current to be inhaled into phenomenon, produces tangible noise and the not smooth phenomenon of suction water; Go into discharge orifice when following when the environment water level drops to the center, submersible pump can't draining, and water can't be drained only.
The model utility content
The entrance guiding submersible pump that the purpose of this utility model is to provide a kind of effective lifting suction water effect and obviously reduces noise.
The purpose of this utility model is realized by following technological scheme:
A kind of entrance guiding submersible pump, comprise water wheels snail lid, discharge orifice is gone at the water wheels snail center of being covered with, it is characterized in that: the front end that discharge orifice is gone at described center is provided with and is used to guide current to enter the guide channel that discharge orifice is gone at described center, the guide channel inlet apart from the distance of water wheels snail lid bottom less than the become a mandarin distance of pitch-row water wheels snail lid bottom of center.
As concrete technological scheme, described water wheels snail lid comprises snail lid body and the fairing cap that is attached thereto, fairing cap is positioned at the front end that discharge orifice is gone at the center, its direction towards water wheels snail lid bottom is provided with opening, discharge orifice is gone at all the other direction centers of enclosing, and forms guide channel between fairing cap inwall and the snail lid body; The opening of offering on the direction of water wheels snail lid bottom on the fairing cap is the guide channel inlet.
As concrete technological scheme, described fairing cap and snail are covered this body by integral forming.
As concrete technological scheme, described water wheels snail is covered in the one side that is provided with fairing cap and is provided with the fairing cap receiving groove, and described fairing cap is positioned at the fairing cap receiving groove.
As concrete technological scheme, the corresponding direction of described fairing cap receiving groove and water wheels snail lid bottom has water intake, and water intake is relative with the guide channel inlet.
As concrete technological scheme, described fairing cap is a square, its left and right, on three direction centers of enclosing go into discharge orifice, its downside opening.
The beneficial effect of the entrance guiding submersible pump that the utility model provides is: be provided with and be used to guide current to enter the guide channel that discharge orifice is gone at the center owing to go into the discharge orifice front end at the center of water wheels snail lid, guide channel inlet apart from the distance of water wheels snail lid bottom less than the become a mandarin distance of pitch-row water wheels snail lid bottom of center, its effect has been equivalent to reduce the height that discharge orifice is gone at the center, like this, be not enough to flood whole center and go into discharge orifice but still flood guide channel when inlet when the environment water level drops to, by the water cavity place by the rotatablely move pumping action of the negative pressure that forms of impeller, guarantee that current still go into discharge orifice through the center swimmingly and enter water cavity, avoided the center to go into the discharge orifice place because obvious noise and the not smooth phenomenon of suction water that the mixing suction of air stream and current causes; Simultaneously, drop to that the center is gone into below the discharge orifice but still when flooding the guide channel inlet, owing to reduced the water inlet height of submersible pump, entrance guiding submersible pump of the present utility model still can continue draining, gets cleaner to the water pump drainage of environment when the environment water level.
Especially, owing to increase by a fairing cap in the water wheels snail lid that guide channel only needs in prior art, make simple in structure, the realization and safe and reliable easily of entrance guiding submersible pump of the present utility model.
Especially,, do not need to make separately fairing cap and increase assembly process, the water wheels snail lid of entrance guiding submersible pump of the present utility model is made easily, hardly with increasing cost because fairing cap and snail are covered this body by integral forming.
Especially, owing to the fairing cap receiving groove is set and has and the relative water intake of guide channel inlet at its downside at water wheels snail lid front end, it is more smooth and easy to make the current of entrance guiding submersible pump of the present utility model enter the guide channel inlet.
