Problems solved by technology

After the pump is turned on, the impeller rotates at a high speed, and the liquid in it rotates with the blades. Under the action of centrifugal force, it flies away from the impeller and shoots out. The speed of the injected liquid gradually slows down in the diffusion chamber of the pump casing, and the pressure gradually increases. The outlet is discharged, and a vacuum low-pressure area without air and liquid is formed at the center of the blade because the liquid is thrown to the surroundings. The liquid in the liquid pool flows into the pump through the suction pipe under the action of the atmospheric pressure on the pool surface, and the liquid is continuous like this It is continuously sucked up from the liquid pool

Example Embodiment

[0023] Example 1:

[0024] Such as figure 1 , figure 2 , image 3 As shown, the low-suction water pump provided by the present invention includes a pump housing 1, a first water outlet 2, a water inlet 3, a motor 4 and an impeller 5. The first water outlet 2 is provided on one side of the pump housing 1. The impeller 5 is fixed on the shaft 7 of the motor 4, and a base 6 is fixed at the bottom of the pump housing 1, and the base 6 and the pump housing 1 form a pump cavity 8. The motor 4 and the impeller 5 are both placed in the pump cavity In 8, an exhaust valve device 9 with a steel ball is provided on the pump housing 1, the water inlet 3 is provided on the base 6 below the position of the impeller 5, and a flow deflector 10 is provided on the upper part of the impeller 5. Such as Figure 4 Said, the deflector 10 passes through the rotating shaft 7 and is sealed with the rotating shaft 7 through a sealing ring 19, and the deflector 10 and the base 6 form an inner cavity 11, an...

Example Embodiment

[0026] Example 2:

[0027] Such as Figure 5 As shown, the general structure of this embodiment is the same as that of embodiment 1, except that a controller 13 is provided in the pump cavity 8 above the motor 4, and a water level sensing head 14 is provided on the pump housing 1. The water level sensor head 14 is electrically connected to the controller 13; on one side of the pump housing 1 are provided an sensor head socket 15 that can be matched with the water level sensor head 14 and three sensor head positioning sockets 16, and the sensor head socket 15 A stainless steel sheet 20 for short-circuiting the induction head is provided inside, and the induction head positioning socket 16 can be determined according to the requirements in the specific embodiment.

[0028] When the water pump needs to be operated manually during work, the water level sensor head 14 can be plugged into the sensor head socket 15 to manually control the start of the water pump. When the water pump nee...

Example Embodiment

[0029] Example 3:

[0030] Such as Image 6 , Figure 7 As shown, the general structure of this embodiment is the same as that of Embodiment 2, but the difference is: in order to make the water flow can be quickly thrown out of the deflector 10, the inner wall of the deflector 10 is provided with a first vortex groove 17 The opening at one end of the first vortex groove 17 corresponds to the water inlet 3 to form a volute. The opening at the other end of the first vortex groove 17 is the second water outlet 12, and is smaller than the diameter of the opening at one end corresponding to the water inlet 3. The other end corresponding to the second water outlet 12 is open.

Abstract

The invention discloses a low-water-sucking water pump, which comprises a pump shell, a first water outlet, a water inlet, a motor and an impeller, wherein the first water outlet is arranged on one side of the pump shell; the impeller is fixedly arranged on the spindle of the motor; the bottom of the pump shell is fixedly provided with a base; a pump cavity is formed by the base and the pump shell; the motor and the impeller are both arranged in the pump cavity; the pump shell is provided with a vent valve device with a steel ball; the water inlet is arranged on the position relatively below the impeller on the base; the upper part of the impeller is provided with a fairing; the fairing passes through the spindle and is in sealing with the spindle by a sealing ring; an inner cavity is formed by the fairing and the base; and the fairing is provided with a second water outlet from which conveying liquid can freely enter and leave. The invention aims to provide the low-water-sucking water pump which has the characteristics of high pumping speed, good effect and long service life, can be automatically started and quickly pumped, can be used for pumping or dewatering water pools, basements or other occasions with the lower water level.

Description

technical field [0001] The invention relates to a submersible pump, in particular to a low water suction pump. Background technique [0002] The submersible pump is a widely used water treatment tool in daily life. The shadow of the submersible pump can be seen in both agricultural production and industrial processing. The difference from ordinary water pumps is that it works underwater. When used, the whole The unit dives into the water and extracts groundwater to the surface. It is an indispensable tool in domestic water, mine rescue, industrial cooling, farmland irrigation, seawater lifting, ship load adjustment and fountain landscape. Before starting the pump, the suction pipe and the pump must be full liquid. After the pump is turned on, the impeller rotates at a high speed, and the liquid in it rotates with the blades. Under the action of centrifugal force, it flies away from the impeller and shoots out. The speed of the injected liquid gradually slows down in the dif...
