Abstract
The utility model belongs to pump technology field, refer in particular to a kind of water inlet structure of pump, including water inlet pipe, described water inlet pipe is the S-shaped structure droped to the ground, the axis of water inlet and the axis perpendicular of delivery port and delivery port are upward, the outline of the water inlet bottom of the tube of delivery port side is circular arc of one section of central angle less than 90 degree, and the starting point of circular arc is the peak of the outline of the water inlet bottom of the tube of delivery port side, the minimum point that terminal is water inlet bottom of the tube outline, and advantage is：Water flows through water supply connector and enters into water inlet pipe, entered into the pump housing along the S-shaped intake tunnel of water inlet pipe, current are unobstructed in water inlet Bottomhole pressure, because the area in the section in the S-shaped chamber in water inlet pipe uniformly increases from water inlet to delivery port, this structure causes that current will not produce collision and be vortexed in the bottom (middle part) of water inlet pipe, the loss of flow energy is reduced, the emptying effectiveness of water pump is improve, while the noise produced during water pump water delivery also greatly reduces.
Description
Technical field
The utility model belongs to pump technology field, refers in particular to a kind of water inlet structure of pump.
Background technology
At present, water inlet pipe typically is connected with traditional water pump, the other end of water inlet is connected with water supply connector, and water inlet pipe is in
S-shaped structure, the arc of the internal diameter more than the water inlet pipe at water pump end of the curved channel in the arc fold bending portion of the water inlet pipe at water supply connector end
The internal diameter of the curved channel of shape bending part, the bottom of the curved channel in the arc fold bending portion of the water inlet pipe at water supply connector end is flat
Structure, in the course of the work, current produce whirlpool to water pump in the curved channel in the arc fold bending portion of the water inlet pipe at water supply connector end
Stream, current flowing is not smooth, disorderly, and the energy loss of current is big, reduces the emptying effectiveness of water pump, and in addition, current pass through
Water inlet pipe can also produce larger noise during entering in the pump housing.
The content of the invention
The purpose of this utility model is to provide a kind of emptying effectiveness for improving pump, substantially reduces the water inlet knot of the pump of noise
Structure.
What the purpose of this utility model was realized in：
A kind of water inlet structure of pump, including water inlet pipe, the water inlet of water inlet pipe one end are connected with water supply connector, the other end
The delivery port connection pump housing, described water inlet pipe is the S-shaped structure droped to the ground, the axis of water inlet and the axis perpendicular of delivery port
And delivery port is upward, the outline of the water inlet bottom of the tube of delivery port side is circular arc of one section of central angle less than 90 degree, circular arc
Peak, minimum point that terminal be water inlet bottom of the tube outline of the point for the outline of the water inlet bottom of the tube of delivery port side.
In the above-mentioned technical solutions, the central angle of described circular arc is 70 ° -80 °.
In the above-mentioned technical solutions, the central angle of described circular arc is 73 °.
In the above-mentioned technical solutions, described delivery port higher than water inlet minimum point and less than the peak of water inlet.
In the above-mentioned technical solutions, rounding off between the terminal and water inlet of the circular arc.
In the above-mentioned technical solutions, the area in the section in the S-shaped chamber in the water inlet pipe is uniform to delivery port from water inlet
Increase.
The utility model is prominent and beneficial compared to existing technology to be had the technical effect that：
1st, during pump working of the present utility model, water flows through water supply connector and enters into water inlet pipe, along the S-shaped of water inlet pipe
Intake tunnel is entered into the pump housing, current water inlet Bottomhole pressure it is unobstructed, due to the S-shaped chamber in water inlet pipe section area from
Water inlet to delivery port uniformly increases, and this structure causes that current will not produce collision and whirlpool in the bottom (middle part) of water inlet pipe
Stream, reduces the loss of flow energy, the emptying effectiveness of water pump is improve, while also greatly reducing what is produced during water pump water delivery
Noise.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the structural representation of water inlet pipe of the present utility model
Specific embodiment
The utility model is further described with specific embodiment below in conjunction with the accompanying drawings, referring to Fig. 1-2：
A kind of water inlet structure of pump, including water inlet pipe 1, the water inlet 4 of the one end of water inlet pipe 1 are connected with water supply connector 5, another
The connection pump housing 3 of delivery port 2 of one end, described water inlet pipe 1 is the S-shaped structure droped to the ground, axis and the delivery port 2 of water inlet 4
Axis perpendicular and delivery port 2 is upward, the outline of the bottom of water inlet pipe 1 of the side of delivery port 2 is that one section of central angle is less than 90 degree
Circular arc, the starting point of circular arc is the peak of the outline of the bottom of water inlet pipe 1 of delivery port side, terminal is the bottom foreign steamer of water inlet pipe 1
Wide minimum point, compared with traditional water inlet pipe, greatly reducing current and exists with the shock of the wall of water inlet pipe 1 and reduction current
Vortex is produced in water inlet pipe 1, current flowing in water inlet pipe 1 is unobstructed, and energy loss is small, improves the emptying effectiveness of water pump, together
The noise that Shi Shuiliu is produced in water inlet pipe is smaller.
The central angle ∠ A of above-mentioned circular arc are 70 ° -80 °.
The central angle ∠ A of above-mentioned circular arc are 73 °.
Above-mentioned delivery port 2 higher than water inlet 4 minimum point and less than the peak of water inlet 4.
Rounding off between the terminal and water inlet 4 of above-mentioned circular arc.
The uniform increase from water inlet 4 to delivery port 2 of the area in the section in the S-shaped chamber 6 in above-mentioned water inlet pipe 1.
Above-described embodiment is only preferred embodiment of the present utility model, and protection model of the present utility model is not limited according to this
Enclose, therefore：All equivalence changes done according to structure of the present utility model, shape, principle, all should be covered by protection of the present utility model
